Changing times Although the coming year may have its challenges, the timber industry continues to offer the chance to build better and more sustainably.


he past year has been a time of change for many, with Brexit still present in every other headline. What the timber industry needs most at this time is certainty – Government leadership that is strong and focused – so that we can plan for a sustainable future, however Brexit may ultimately impact our economy.

Despite the odds, the construction industry thrived throughout 2018, with continued healthy projections for 2019 – especially in the residential sector. Brexit has provoked change, but also provides new opportunities. As an industry, timber offers three key fundamentals, which it can offer in unison. These are: • a digital delivery platform (BIM) • off-site manufacturing (DfMA) • the use of green, sustainable technologies. This enables the timber industry to support the Government’s initiative for off-site construction in a way that no other form of construction material can.

Combustible materials and cross-laminated timber The main challenge in 2019 for both timber products and structural timber building systems is the UK Government’s ban on the use of combustible materials in residential buildings above 18m. We must embrace it and put in the work necessary to reassess how we design our buildings and how we product test for specific use in external walls. Above all, this is something that we must undergo collaboratively, with knowledge that must be shared throughout the industry. Never has it been so important that we unite as one voice. I am therefore pleased to advise that TRADA will be supporting the UK CLT hub led by Waugh Thistleton Architects, which aims to bring industry stakeholders together with the intention of collaborating and addressing key issues such as durability, fire and cost. As TRADA, we can create specific and robust technical publications fit for consumer guidance and confidence.

our deepest appreciation for the time and commitment he has shown during his reign as both Chief Executive and Director. We welcomed David Hopkins, Managing Director of the Timber Trade Federation (TTF), to the Board of Directors. David’s experience, talent and passion will undoubtedly strengthen TRADA’s position as the go-to centre of timber excellence for both research and technical guidance within the UK timber industry. We are excited to see how TRADA can work together with the TTF to expand on our University Engagement Programme. I would also like to take this opportunity to thank Charlie Law, a long-standing Director on the TRADA Board, who has stepped up to the role of Vice-Chairman. His support will be essential as TRADA expands on its current offering both domestically and internationally.

Better Timber Buildings Another 2018 highlight for TRADA was our Better Timber Buildings conference, held at the Royal Geographical Society, London, in partnership with our service provider BM TRADA. With around 200 delegates and exhibitors, this well-attended event was our first since 2008 – and we will certainly be looking at doing the same again in 2019. An expanding community TRADA’s reach has experienced tremendous growth over the past year. Not only have we seen an increased number of publication sales to the US, Canada, Singapore, Australia and New Zealand, but TRADA staff have been requested at conferences around the world. In line with this, I am also delighted to share that we have seen an increase in our UK membership numbers – a reflection of the hard work put in by the TRADA team – which supports the growth we have witnessed of the UK timber industry as a whole. n

TRADA news Board changes In keeping with the theme of change, 2018 saw the departure of Andrew Abbott, who stepped down from his role as Director at TRADA. On behalf of the TRADA Board, we would like to express www.trada.co.uk

TRADA Review of the year

Will we rise to the opportunity? Rupert Scott reflects on a year of switching tack at TRADA.


here is something to be said for looking back. If you spend too much time looking forwards, you forget how far you’ve come. Here at TRADA, it’s easy to forget how far we’ve come – especially when we started our journey in 1934 as the Timber Development Association (TDA).

Some of our recent bestsellers, including Structural timber elements: a pre-scheme design guide and Crosslaminated timber: design and performance, have been added to the Books Online area on the TRADA website, which means the total amount of technical information we can offer is growing.

Since then we’ve developed software, written books and produced thousands of online publications, all in the name of sharing our love for timber. Just as the timber industry has changed and matured since then, so has TRADA: our goal remains the same, but we’re no longer standing on the same pitch.

Publications The TRADA publishing team has been hard at work over the past year, delivering a programme of guidance that combines the necessary updates to existing publications – among them the Timber decking book, which had its 3rd edition released in October 2018 – and the production of new ones that have become increasingly necessary as a result of a changing market. Site check: the timber frame pocket guide was released in February 2018 and equips site managers with illustrated best practice checklists that empower them to ensure subcontracted work is carried out to the highest standard.

TRADA held three stands at the 2018 Timber Expo as part of UK Construction Week


TRADA’s latest publications


We believe that exhibitions are an irreplaceable tool for any sector. After all, they allow us to share our enthusiasm for timber, demonstrate our expertise and interact with members of the timber industry all in one place. We are planning on maintaining our conspicuous presence at both Futurebuild (formerly Ecobuild) and Timber Expo going forwards. Despite the broad spectrum of information at our fingertips on the internet, nothing beats the connection and the dialogue that comes from human interaction. >> Timber 2019 Industry Yearbook

TRADA Review of the year

There was a strong furniture category in the 2018 Wood Awards

Wood Awards


We now have more than 100 case studies on the TRADA website, many of them winners at the prestigious annual Wood Awards. Each year we are behind the scenes answering your questions, processing your entries and creating the judging packs – enabling the judges to choose the Wood Awards shortlists with as much ease as possible. This opportunity, alongside co-manning the Wood Awards stand at the London Design Fair, allows us to see every project entered in detail; this year we were pleased to see an incredibly strong furniture category.

November saw the success of our Better Timber Buildings conference which was inspired by our belief that we need everyone’s contribution to mature the timber industry. The conference encapsulated the values we hold as an association. Not only did we draw a varied crowd across the whole construction supply chain, indicative of our broad appeal, the speakers we invited spoke on topics we are fiercely passionate about – including priorities for the sector in the 2020s, fire performance of timber cladding, designing for durability and so much more. We wanted to provide a conference of utmost value, where every component was designed to enthuse or educate. We hope those who attended agree that we succeeded. n

Urban Buzz 2018 also saw us rejuvenate our annual student design competition by introducing a brand new format. Students were split up into multidisciplinary teams of five and challenged to design a timber multi-storey car park within 36 hours to a clear but comprehensive brief. The resulting designs impressed our judges, with Matt Caldwell, Senior Structural Engineer at BuroHappold, hailing them ‘a credit to our next generation of designers’, while others commended the students’ passion for timber. Our goal remains unchanged: we seek to raise the profile of timber and see it represented fairly alongside other mainstream construction materials in engineering and architectural courses. Clearly we’ve made progress, but there is still more to be done. www.trada.co.uk

TRADA Timber Expo

Highlights from the 2018 event TRADA’s Timber Focus Theatre offered a platform from which to showcase the best of timber.


imber Expo provides the perfect opportunity to engage with TRADA members and meet others across the timber industry. With the Timber Focus Theatre, University Engagement stand and a range of activities (some with prizes!), we are perfectly poised to chat to people of various backgrounds, interests and expertise. Challenges set by TRADA’s timber experts, such as ‘Guess the species’, lead naturally into deeper discussions and firmer relationships between industry professionals.

Timber Focus Theatre TRADA’s main event in the construction calendar has long been Timber Expo and the highlight is, of course, the seminar programme in the Timber Focus Theatre, which runs every year and for which the planning commences many months earlier. The 2018 event featured a slight change in format, with more emphasis placed on specific areas where guidance is needed and regularly asked for. The hope – to showcase beautiful timber with carefully integrated guidance and discussion.

We interviewed multiple panels, which included PLP Architecture’s Kevin Flanagan, Gardiner & Theobald’s Oliver Booth, Smith and Wallwork’s Simon Smith, and Changebuilding’s Adrian Campbell. Stage highlights involved necessary changes to specification, procurement and research exchange to progress the timber agenda – innovations suggested by forerunners of the industry. We also held two daily CPD sessions to cover an abundance of crucial topics, including connections, tall timber, and designing for durability and repairability. Timber cladding and fire-resistant doorsets sessions ran on a daily basis, following a heightened awareness post-Grenfell.

Daily CPD sessions were held at the event

The Timber Focus Theatre was the highlight of Timber Expo

MawsonKerr Architects’ Will Mawson, KnoxBhavan’s Sasha Bhavan and Rogers Stirk Harbour + Partners’ Toby Jeavons, together with Arup’s Paul Edwards, looked behind the scenes at several awe-inspiring timber case studies, including the Sunbeams Music Centre and the Macallan Distillery – two exquisite examples of timber buildings.

From anecdotes about the first time Waugh Thistleton Architects’ Anthony Thistleton was exposed to cross-laminated timber, to larger ideas repeatedly highlighted by speakers – such as the importance of collaboration, particularly in the design stage – the seminars demonstrate that the Timber Focus Theatre continues to be an excellent platform for understanding exactly what’s going on in the industry. We also welcomed Andrew Woolcock and his stunning rosewood marimba to the Timber Focus Theatre. Andrew, who won BBC Young Musician for Percussion in 2016, absolutely delighted attendees with his terrific blend of contemporary selections, giving lucky enquirers a go at playing the larger-than-life instrument.

The installation – State 2 – from the Royal College of Art Earlier on in 2018, TRADA joined forces with Hanson Plywood, Timber Expo, Grymsdyke Farm and the Royal College of Art’s Manja van de Worp to investigate flexible construction systems for housing using plywood panels.

The initial multidisciplinary workshop at Grymsdyke Farm, which encouraged both individual abstract exploration and collaboration, led to the conception of an ‘alphabet of elements’. Constructed of 9mm plywood, each ‘letter’ handles a specific condition within the construction system based on geometry, configuration and location. The structure on display at Timber Expo was an expanded version of the more closed, compact structure initially assembled at Grymsdyke Farm, and was discussed by Manja van de Worp at length when she took the Timber Focus Theatre stage on the final day.

University Engagement Programme Tabitha Binding, TRADA’s University Engagement Manager, manned her own stand dedicated to the programme while armed with Learning Resources. The programme, which seeks to instil a love for timber while students are still attending university, provides free academic access to a selection of our research and supports the annual TRADA University Challenge. Tabitha took the opportunity at Timber Expo to highlight the TRADA University Challenge 2019, which took place in Sheffield in February. n

TRADA Education

Teaching timber Tabitha Binding, TRADA’s University Engagement Manager, addresses the need to engage with students to help the growth of the timber industry.


imber, as a growing renewable resource that absorbs CO2 and sequesters it into buildings, is the construction and building material of the 21st century. Available in a wide variety of species, timber can address a full range of design situations, from salt water to arid climates. If we are to capitalise on the advantages that timber brings, students leaving higher education must know how to design, engineer, specify, construct and price projects that include timber and timber products, elegantly, economically and effectively. After taking over the University Engagement role for TRADA in 2018, I am only just scratching the surface of all the higher education institutions. However, I have so far found that, apart from a few pockets of real knowledge, timber is hardly taught at all. The majority of current students now leave higher education never having handled a piece of timber, let alone understanding the difference between a hardwood and a softwood, or that durability can be innate to a species or conferred by different methods of preservation. TRADA aims to address this lack of knowledge by working closely with the timber industry and professional partners, building on and expanding its current engagement with both lecturers and students.

TRADA’s resources University membership Many of TRADA’s resources are available free to students and lecturers who sign up online via the TRADA website. Full university membership is a cost-effective way to provide both students and academics with the full range of TRADA’s resources, including an intranet link, direct course support and lectures, dedicated competitions and lecturer training opportunities. If you are interested in working with TRADA, please contact either Kathryn Macneil (kathryn.macneil@trada.co.uk) or myself. Learning resources Available free online to all students and lecturers, these resources can be used for self-study or incorporated into courses. The eight sections and 64 modules, starting with ‘Timber as a material’ lead you through timber characteristics, environmental aspects, connections, www.trada.co.uk

engineering, construction principles, and fire resistance and timber buildings. Several ‘Question and Answer’ sections are currently in development to help you test your knowledge.

Case studies With more than 100 examples of timber in construction, from bridges to high-rise residential buildings, each case study is populated with architectural drawings, images and engineering details. The case studies also include project information, background information and construction methodology. Timber lectures Free to full TRADA member universities, we work with individual lecturers and departments to make each lecture relevant to the year and course. Spending up to a day onsite, we supplement the talks with relevant timber samples, competitions and books.

Student competitions Multidisciplinary competition In 2018, TRADA ran its first multidisciplinary competition – Urban Buzz. The competition brief – to design a car park from timber – saw 30 universities and 60 students from the disciplines of architecture, architectural technology, landscape architecture and engineering compete for cash prizes. The twoday charrette-style competition, held at The Diamond building at the University of Sheffield, was sponsored by industry partners Arnold Laver, Timber Trade Federation (TTF), Stora Enso, OSC Fasteners and Hanson Plywood. Representatives of each company engaged directly with the students during the competition, greatly improving their product knowledge. >>

TRADA Education

Judges from Cullinan Studio, Waugh Thistleton Architects, Arup, BuroHappold, ARES and HLM Architects were on hand to guide and offer advice prior to judging the teams’ outputs, providing critical feedback. Building on the success of Urban Buzz and now badged as TRADA’s University Challenge 2019, this year quantity surveying students were added to the mix. Sponsored by Steico, TTF, Stora Enso, PEFC and Wood for Good, and held on 8–9 February 2019 in Sheffield, the results and review are available online at www.trada.co.uk/academic-competitions/ university-challenge-2019. The competition will be moving venues in 2020 and TRADA is seeking a new host. If you would like to offer your university facilities, please get in touch.

TTJ university research competition Acknowledging work that university students carry out at both undergraduate and postgraduate level, breaking boundaries and demonstrating a measurable impact on the timber sector, TRADA and Timber Expo jointly sponsor the TTJ Timber Innovation Award for Innovative University Timber Research.

The project was an investigation into the limits of smallsection timber under tension, which involved an intricate and lightweight anticlastic timber net, and the resulting structure serves as a full-scale prototype for later builds by consecutive students at Hooke Park. Runner-up of the University Research category was Joshua Mudie from the University of Bristol with his research insight into the mechanics of externally indeterminate hardwood–concrete composite beams, detailing how concrete and timber can be made to work together. Research from both projects is available to view at www.trada.co.uk/ research-projects. Entry for the 2019 competition opened in February. For further details, or an application form, please get in touch.

Who teaches the teachers? TRADA is collaborating on a five-year education plan with the East Anglia Timber Trade Association (EATTA) and industry sponsors to update lecturers from the region’s universities on their knowledge of today’s timber production.

Open to third-year undergraduate or postgraduate (Masters or PhD) students, the judges are looking to find the entry that demonstrates the maximum degree of innovation applied, backed up by evidence. In 2018, Rolando Madrigal Torres, Evgenia Spyridonos, En-Kai Kuo and Eleni McKirahan, four students from the Architectural Association’s innovative Design + Make programme, won the University Research category for their work on the Sawmill Shelter.

SCA explain how their Swedish forests are managed

Invited and accompanied by myself, three key university lecturers from the Universities of Anglia Ruskin, Suffolk and Hertfordshire travelled to Sweden in September 2018. The visit was arranged by EATTA as part of its new ‘Who teaches the teachers?’ programme and was hosted by the Industrial Solutions operations of Timber Trade Federation member SCA Wood.

The three-day trip involved visits to: • SCA’s tree nursery where 100 million tree seedlings are produced each year • SCA’s sustainable forests, of which SCA owns 2.6 million hectares in northern Sweden • Tunadal Sawmill – one of five sawmills owned by SCA in Sweden.

TRADA Education

Stephen King, Sales Director of SCA Wood Industrial Solutions, comments: ‘We were delighted to be asked to host this visit by the EATTA. SCA has always been dedicated to sharing our wealth of timber knowledge with our customers, but the education we provide shouldn’t stop there. We are firmly rooting our commitment to the timber industry to help engage those responsible for inspiring the engineers and architects of tomorrow. Seeing our operations first-hand will hopefully provide lecturers with the experiential knowledge they need to impart enthusiasm for wood use in construction to the next generation.’ The lecturers came from both architectural and engineering disciplines. ‘The aim is for each lecturer to enliven students’ and colleagues’ interest in the timber business and in timber as a sustainable building material,’ says EATTA Chairman Chris James of Nason Davis. Planning is underway for the next educational trip with industry sponsor VIDA hosting our visit this year. It will take place in early September 2019 and we have three lecturer places available. If you would like to get involved, please get in touch.

Hands-on learning As part of my role, I plan to engage with, encourage and promote more hands-on learning. Kate Darby, a part-time lecturer at Cardiff University’s Welsh School of Architecture, invited me to attend Studio in the Woods 2018 to see how one group of practitioners has developed this concept. Established in 2005, Studio in the Woods is an ongoing education and research project, founded and convened by Piers Taylor (Invisible Studio) with Kate Darby (Kate Darby Architects), Meredith Bowles (Mole) and Gianni Botsford (Gianni Botsford Architects), designed as a vehicle to test ideas through making at 1:1. Each year, the founders are joined by several practitioners and academics in leading workshops for participants over three or four days. The 2018 studio ran from 5–8 July and was hosted by the Wyre Community Land Trust and the Guild of St George in Ruskin Land, Shropshire. The woodland is 99% oak and sits on land originally gifted to John Ruskin, and is where he established the Guild of St George in the 1870s. The founding aim of the Guild was to acquire land and – through labour, wind and water power – bring it into useful production. The focus of the studio was the exploration of future uses for the timber of the Wyre Forest, which is predominately oak and has been unmanaged for several years. Participants split into six groups, and over the three-and-a-half days selected their building materials, conceived their designs and then www.trada.co.uk

constructed them. Critical feedback on the six designs was given on the last day by architects Niall McLaughlin, Robert Mull, Peter Clegg and Ted Cullinan. The 60 participants from varied backgrounds included several university students. Jamie Rest, who is returning to the University of Sheffield to study for his RIBA part 2 after his year out in practise with Architype, commented: ‘Making is an essential skill in architecture yet we rarely physically engage in the act of building at 1:1. Making by hand and at full-scale forces us to understand materials and how they come together in a way that is perhaps difficult to be taught in an academic context. By seeing making as part of the design process as opposed to "making the design", projects are often enhanced as a result of the happy accidents and discoveries that are made along the way.’

2019/2020 During the coming year TRADA is exploring other engagement activities with material libraries, site visits, dedicated lecturer days and further competitions in the pipeline. If you would like to get involved, or have any queries or requests, please get in touch. n

This eye-catching pink pavilion sits in the centre of the 18th-century walled garden originally designed by Georgian landscaper Lancelot ‘Capability’ Brown. The structure is made from birch ply and fabric, and is based on a rectangle of paper that has been folded in a way that gives it structural stability and creates a sense of shelter. Engineered ply was cut using a five-axis CNC. It won the Small Project category at the 2018 Wood Awards and more information can be found at woodawards.com/look-look-look

Curved cladding4 Charred timber clads the tiered balconies in Sydney’s redeveloped Barangaroo South precinct. The cladding is made from concentric timber dowels, which were individually steam bent and laminated. The dowels, constructed from Accoya, were charred using the traditional Japanese Shou Sugi Ban technique, creating a dark finish. For more information, go to www.dezeen.com

Timber structures Wood Awards winner

“The building has been designed as an exemplar of sustainability and timber has been used throughout, both inside and outside, to achieve this.”


torey’s Field Community Centre and Eddington Nursery is a building of rare quality; shortlisted for RIBA’s Stirling Prize, it is cited as demonstrating ‘how an architect can add joy, an enhanced experience of materials and human dimension to every part of a building’.

It sits at the heart of the new village of Eddington, in north-west Cambridge, part of the university’s new town and only recently populated with residents – Cambridge postgraduates and key workers, together with their families.

Multi-purpose space The architect, MUMA, was deeply involved in the briefing process from the start, which evolved into two requirements: • a community hall large enough to seat 180 people, to act as a civic centre and a place for weddings, concert performances, local groups and parties • a nursery for 100 children. The architect has integrated the two together in a plan similar to a Cambridge college; the vertical volume of the hall – like a college dining hall – forms one side of an expansive courtyard that is enclosed on the other three sides by the single-storey nursery, together with staff offices and public toilets. >>

The generous volume of the main hall, inspired by the dining halls and chapels of Cambridge colleges, is large enough to accommodate a wide range of activities and acoustic performances, from chamber music to film screenings. Timber is used to create a unique sense of place, with oak, ash and spruce establishing layers of soft, warm tones appropriate for a dignified community gathering space. Each layer of timber is designed to modulate the scale of the hall, and the tones of the material are progressively lightened as they rise to upper levels. The choice of timber was also vital to achieve the quality of acoustics within the space. The lower parts of the north and south walls are lined with carved solid oak ‘linenfold’ panels, providing a surface of varying depths to scatter sound waves and so enhance the quality of sound. Within them are sets of bespoke concealed acoustic doors.

The courtyard is a children’s play space and a sheltered cloister runs along its edges. The three nursery classrooms open directly on to the courtyard so that children can play freely outside in privacy and safety. The three classrooms have lofty inclined ceilings, expressed externally by three pitched turret roofs clad with cedar shingles. All of the public spaces are adaptable; the walled garden next to the main hall can be part of a wedding celebration, but can also be used for quiet reading for nursery pupils. The main hall, 10m high, acts as the focal point to the new village centre and its main entrance is set back to create a communal gathering space, with stone benches inset into the walls for locals to sit and chat. The external walls are buffcoloured brick to match the requirements of the masterplan, but profiled with projecting bands of header and stretcher courses to create depth and shadow.

The use of timber in the main hall

The building has been designed as an exemplar of sustainability and timber has been used throughout, both inside and outside, to achieve this. The use of timber in the main hall has also been key to creating a warm and welcoming environment with a high-quality acoustic performance. www.trada.co.uk

Above the panels a series of slender spruce glulam portal frame columns emerge, which rise in front of a backdrop of ashveneered wall panels and, higher up, a glazed clerestory. The glulam frames stand proud of the glazed clerestory to create a zone where acoustic banners have been installed; they can be raised or lowered to provide different acoustic qualities to suit different performances. The glulam frames are spaced at irregular intervals, within a range of 600mm, 900mm and 1200m, to break up sound reflection and create a warm, smooth sound. The west wall has an open mezzanine, clad with timber, and the brick wall above is profiled with projecting brick courses, creating a surface of depth and shadow that helps to soften the acoustic. The east wall is fully glazed at low level with sliding glazed doors that open on to a garden. The upper level is of profiled brickwork to match the west wall. The ceiling is a lattice of solid ash joists on battens that conceals air extract routes for the hall’s passive ventilation strategy. Above this is a series of deep timber trusses that act as an acoustic attenuation zone, controlling noise break-in and break-out. During the day, natural light floods through the clerestory and glazed openings, while at night, lit from within, the hall acts as a lantern to the new village. >>

The timber structure

The main hall structure is a series of remarkably slender glulam portal frames, 500mm wide but only 80mm thick, yet with columns that reach 7.5m in height and beams that span more than 10m. Drawing of the main hall. Drawing: Neue Holzbau To achieve such slenderness, the Swiss manufacturer Neue Holzbau selected spruce lamellas that were of the highest quality of strength class, as well as the highest visual grade (the frames are finished with a white translucent stain). The portal frames support paired edge beams, each 450mm x 200mm, which in turn support the roof structure, a set of deep glulam trusses, spaced at irregular intervals to achieve the necessary openings for the acoustics and ventilation strategies. Four 480mm x 240mm glulam columns stand at the corners of the structure to reduce horizontal deflection. The glulam portal frame beam and columns are connected by concealed joints using GSA® Technology, a proprietary connection system developed by Neue Holzbau. The system uses threaded rods glued to the timber and secured with epoxy resin, resulting in a concealed, protected and fire-proofed connection. Neue Holzbau designed, supplied, delivered and installed the timber structure.

The spiral staircase

A timber spiral staircase rises more than 8m from the mezzanine to give access to the roof. It has a diameter of 1580mm and the treads are constructed of steel plate overlaid with ash veneer. The balustrade is of 25mm-thick ash veneered plywood with a solid ash handrail. At the base of the staircase is a stair gate in ash veneer with concealed hinges and lock.

Sustainability The project is part of the North West Cambridge Development commissioned by the University of Cambridge. The university undertook to make the development an exemplar of sustainability. As part of that brief all projects in the development had strict criteria to uphold, including sustainably sourced products. In addition, the project was to achieve BREEAM Excellent. The project has surpassed this goal and achieved BREEAM Outstanding for the Community Centre and Excellent for the Nursery, with the extensive use of timber contributing to the result. All the timber used is PEFC and FSC certified. The volume of the hall allowed a passive ventilation strategy to be incorporated using a stack effect. Fresh air is drawn through a labyrinth below the floor and extracted at high level through openings in the timber ceiling.

Timber structures Housing

“Build-to-rent developers and investors are in the market for the long haul; choosing higher-end materials both within the building’s fabric and the fit and finish that will stand the test of time.”


uild-to-rent, the market for privately rented residential schemes that are specifically designed and built for rent rather than sale, is gathering momentum. In April 2018, the British Property Federation estimated there were almost 120,000 build-to-rent units already built, under construction or in planning across the UK; a 30% increase over the previous year, and this number is expected to grow.1

What is build-to-rent, what role can it play in addressing housing needs across the country and what are the opportunities for the timber industry?

What is build-to-rent? Build-to-rent properties are primarily owned by institutional investors who require a long-term rental growth for pension savings. The properties are usually located in urban city centres and managed by specialist operators such as Moda Living, Dandara Living, Greystar and LIV Consult. Typically, build-to-rent schemes target young professionals, students and downsizers who buy into the lifestyle and convenience of well-built properties with a superior fit and finish, offering extra services such as gyms and concierge, and that are close to local amenities. However, build-to-rent schemes are also ideally placed to provide families with children longer term, stable rentals. Build-to-rent developers and investors are in the market for the long haul; choosing higher-end materials both within the building’s fabric and the fit and finish that will stand the test of time. This is in stark contrast to those properties built for sale where cheaper materials and finishes are frequently specified to maximise profits for the developer.

The public sector and affordable housing Build-to-rent isn’t just for the private sector; housing associations and local authorities are now also entering the market, helping to ease the pressure on the private rental market and keep rents at a manageable level. In early 2018, Clarion Housing Group and Places for People announced plans to develop build-to-rent >> www.trada.co.uk

Delivered by CCG and constructed quickly using closed-panel timber frame, the new properties offer energy savings to residents, helping to tackle the issue of fuel poverty.

portfolios. Their aim is to help relieve the housing shortage while also generating revenue to fund further housing developments. Frequently, as part of a new build-to-rent development, planners stipulate that a proportion of the properties should be for affordable private rent, usually using the discount market rate model. The Government proposes that, in these cases, a minimum of 20% of the homes should be provided at a minimum of 20% discount.2

The Government expects that family-friendly tenancies of three years or more will become the norm (for those tenants who want one) in the build-to-rent sector.2

The benefits of build-to-rent According to the Ministry of Housing, Communities & Local Government2 there are four main benefits of build-to-rent.

In March 2018, Prime Minister Theresa May pledged to tackle the housing crisis head-on, with one key area being a shakeup of the rental market, introducing longer-term tenancies that are more suitable for families.

Boosting supply Build-to-rent developers often prefer town centre sites for higher density housing that can be less attractive for traditional housebuilders. Modern methods of construction lend themselves well to the build-to-rent model, as housing can be built faster, providing revenue streams for investors more quickly.

As a business model based on a long-term income stream, build-to-rent lends itself well to offering longer tenancies if required, especially for families with children. Meeting this need has become more important as 38% of households in the privately rented sector have dependent children, a proportion that is steadily increasing every year.3 Build-to-rent also offers a long-term housing solution for the large proportion of millennials who are not ever expected to make it onto the housing ladder as prices continue to rise.4

Quality and choice Build-to-rent schemes are built and professionally managed on a scale that typically allows a higher level of services and amenities such as an on-site concierge and communal space. The investor is incentivised to maintain not only the apartment itself, but also the building and the wider public area. As the build-to-rent business model is primarily based on income rather than capital gains, landlords will aim to attract and retain customers by offering a good service. >>

Dalston Works in Hackney, London. By Waugh Thistleton for Regal Homes. Photo: Daniel Shearing Designed by Waugh Thistleton Architects and managed by Regal London, the 121-apartment Dalston Works development in Hackney was constructed entirely using CLT, from the external, party and core walls, through to the floors and stairs. At the time of building, it was the largest load-bearing timber structure in the world.

Economic growth Build-to-rent schemes can contribute to town centre regeneration and accelerate local authority revenues in the form of council tax, new homes bonus and business rates, in addition to creating value from surplus public sector land. Several cities have seen build-to-rent as a way to attract and retain the skilled mobile labour force that their local economy needs. Investment appetite Once completed, build-to-rent schemes provide a relatively low-risk and predictable income stream, which is well suited to the needs of investors such as pension funds seeking to match their inflation-linked pension liabilities.

What benefit does timber construction bring? Cross-laminated timber (CLT) and timber frame buildings are fast to construct and lightweight, meaning they can be used for sites where loads may be an issue. Materials can be combined to offer a range of off-site solutions and speed up construction. The timber engineering used to create CLT ensures greater energy efficiency, strength, durability and acoustic qualities if designed correctly. www.trada.co.uk

In addition, interiors can be manufactured off-site and, when combined with processes such as Building Information Modelling (BIM), can be designed to fit an exact space. These processes reduce waste and make installation easier for kitchen and bathroom pods.

Health, well-being and build-to-rent The aspiration for a healthy lifestyle sits well with the build-torent model. Many developments are built with on-site gyms, are close to public transport, and often provide links and landscaping to encourage people to walk or cycle. Building with timber not only enables developers to create sustainable buildings, but also to offer homes that are aesthetically pleasing, increase health and well-being, and instil a sense of calm in tenants. Both timber frame and CLT structures can provide airtight solutions and natural ventilation, and often result in lower energy bills for the occupiers. >> Timber 2019 Industry Yearbook

The future of build-to-rent

Further information

With the challenges of both availability and affordability, the build-to-rent sector can help to provide more much-needed homes in our towns and cities. In the 2017 housing White Paper5, the Government welcomed build-to-rent as a desirable and enduring feature of the UK housing market.

For more information about build-to-rent and the timber industry, visit www.woodforgood.com and sign up for a regular monthly newsletter.

However, build-to-rent is still a fledgling market with major challenges being the availability of land, achieving planning permission and the competition for land among developers. Build-to-rent developments also need to tread a fine line between being affordable for renters and delivering reasonable profits for the investment institutions that are funding them.

“Building quicker and building sustainably means the enhanced use of timber as a building material, from timber frames to cladding, internal joinery and kitchens to single-ply roofs and landscaping.”


f anyone in Britain is going to come close to building the Government’s target of 250,000 homes per annum in the next 15 years, the housebuilding market needs to change. No amount of political rhetoric will kick-start a housebuilding programme of any shape, size, design or scale until the system that dictates the market is fundamentally addressed.

Three of the many obstacles to overcome are: • the demise of the small- and medium-sized (SME) builder / developer in the market • the difficulty of embracing modern methods of construction (MMC) • building better and more sustainably.

Why are we facing these challenges? There is very little incentive for independent varied housebuilding development in the UK. SME businesses are often described as the backbone of the UK economy and yet the number of SME developers reduces each year and is always decimated after every recession, as proved by the figures since the 1980s. This has to change. But that change is unlikely to come from the industry due to too many vested interests. This could be a Government issue, but it cuts across all political, national and council boundaries. The politicians and the industry have to come together, recognise their own failings and try to promote highquality, varied architecture from SME developers and builders. The national developers have proved resistant to change. This is due partly to the difficulty of change when building at their scale, but more importantly because they see no need to change when their share prices are soaring and bonuses are flowing – build the same and don’t change the model if it works.

Finding solutions A possible increase in supply and housing variety can come from SME developers and the promotion of the old-fashioned >> www.trada.co.uk

builder / developer model over the whole country. After the Second World War, such firms used to build the majority of houses in the UK. Quality and innovation flows from this sector as often they are firms rooted in the local community and want to build for local people and build well; if you see your clients in the local shops you want to make sure they are happy in their homes. Building quicker and building sustainably also means the enhanced use of timber as a building material, from timber frames to cladding, internal joinery and kitchens to single-ply roofs and landscaping. Timber needs to play an increasing role in the sector and the ease with which the industry can step up and gear up before other MMC materials come online means its promotion is paramount to the future of housing supply in the UK.

Housing development process The housing development process consists of different stages. The list below is not exhaustive, but it does show the difficulties encountered by SME builders / developers.

The planning process All too often this is ‘anti any development’ and not ‘pro good development’; this could be due to inbuilt scepticism in council planning departments having seen awful development in the past and the psychology of departments to expect more of the same. This makes it harder to push through an innovative, sustainable, high-quality scheme as the door needs to be pushed harder from the beginning. Not all councils are the same and some are better than others, but you can spend years building up a reputation for good development in an area only for the officers to move on or retire, taking you back to

square one. The actual process of a planning decision should be structured around good development and firms who want to build better – it needs to be systematic. One idea could be for local councils to have a planning tsar to sit above the statutory consultees and be senior enough to promote particular development that the council thinks will add value and benefit the community. Sustainable and good-quality development could then be promoted and given planning decisions quicker, helping small firms’ cash flow and risk profiles.

The development loan The residential development loan industry has dramatically changed and reduced in size since the last recession with many high street banks now completely pulling out of all loans under £5m, the exact tranche size for SMEs. Many people would not recognise the international banks and boutique finance institutions who are in this sector now; the loans are scarce, expensive in fees and rates, and need very high levels of security. Even if you do manage to apply and pass the initial vetting, the fact that you are looking to build differently or use MMC will make the process more difficult. The finance world is driven by the ‘comparable’ world – if there is no proven comparable to value against, the risk is too high – so no loan. The Government must do more to encourage banks to help communities and promote finance options for builders and developers who want to build houses. The Government could also help or fund banks to have more time to look into MMC methods and materials, and talk to small developers – try to make the process less of a tick-box exercise. So the land has been bought, the planning permission granted and the loan agreed ... easy ... no.

The construction phase The difficulty with building differently and using MMC is that firms are still not used to it. Using a main contractor would give price certainty, but any contractor looking at a different specification will price in a buffer just in case. Hence any deviation from normal construction will cost more. Also, if firms can find work doing what they always do, why waste time learning about a new method of construction. After all, time is money, either to the client or the contractor. It becomes harder to have competitive tendering if your housing model is different in any way; it either costs more or firms are not interested. Timber frame construction is now accepted in the industry as being standard. However, if you add timber thermowood cladding to the exterior, airtight buildings, heat pumps and mechanical ventilation with heat recovery, and top it all off with a sedum roof, you are suddenly catapulted into the unknown.

driven. This means that banks do not have enough time to delve into the scheme and see why it is different. Why is there no boiler in a Passive House? Why is there grass on the roof? The difficulty of gaining a mortgage, even with a structural warranty in place, when your construction method is new or modern or different, is astounding. Banks and the Government are trying to change this and promote quicker and different ways of building, but it needs to happen faster, and housebuilders must be more adventurous by embracing different types of building materials. n

Finally, you have your development scheme, your dreams and plans have been realised, and all you have to do now is sell it to make a profit and move on to the next site, but wait ...

Mortgage finance Mortgage finance is probably one of the largest obstacles in the sector to building differently commercially. If all your home buyers were cash buyers then no problem, but as soon anyone needs a mortgage you need the approval of banks. Currently the sector is based on very low-margin and high-volume business, so it is very much process and tick-box www.trada.co.uk

Timber structures Well-being/off-site construction

“I expect that the users of our buildings will come to expect the same standards in sustainable construction as they are starting to demand in the supermarket aisles and at the local pub.”


ver the past ten years or so, the UK property development and construction industries have taken a greater interest in timber. For those who have a predisposition towards sustainable products, timber as a construction material is an obvious choice. It is positive to see both clients and contractors embrace timber with increasing confidence, as incumbents and new starters alike look towards mass timber and new methods for the delivery of buildings.

Sustainability and well-being There has been a noticeable change in attitudes towards natural products and the pursuit of wellness in everyday life and consumer products. There has also been a huge shift in consciousness regarding plastic and plastic waste since the airing of David Attenborough’s Blue Planet II documentary in 2017. Single-use plastic, particularly plastic bottles and drinking straws, has become a public enemy. The long-term impact of this material awareness on architecture is as yet unknown, but clients and designers should take heed of the general public sentiment. I expect that the users of our buildings will come to expect the same standards in sustainable construction as they are starting to demand in the supermarket aisles and at the local pub. This trend has also been growing in workplaces for some time. Many employers have identified staff wellness as a priority and are aware of the benefits that natural materials and indoor vegetation have on the productivity and general morale of staff. Timber’s natural tactile surface and organic patterns provide a warmth to building interiors that is conducive to creating a calming environment. This is supported in numerous research studies and much anecdotal evidence of workplaces that address staff wellness – where workplaces that use timber elements in construction consistently report positive effects on the building occupants. Documented improvements range from: • increased productivity • calming effect on building occupants • reduced absenteeism and office illnesses.1 >> www.trada.co.uk

Creating a healthy building was at the fore of the design process of dRMM’s Maggie’s Centre in Oldham, Greater Manchester. Funded by the Stoller Charitable Trust, the project is one of the series of Maggie’s Centre facilities that provides practical and emotional support to those affected by cancer. The building is a direct reversal of the institutionalised environments so typical of healthcare architecture and instead creates a space defined by hope, humanity, scale and warmth.

The use of timber was considered at every opportunity; from the structural tulipwood CLT and the fluted timber external cladding to the ceiling formed from tulipwood offcuts. The smallest of details were considered from the perspective of the building users; because those undergoing chemotherapy sometimes feel pain on touching cold objects, oak rather than metal door handles have been used. Wood fibre insulation ensures a breathable, healthy environment, while the huge window frames are American white oak. The ceiling is formed from tulipwood offcuts. Photo: Jasmin Sohi

Maggie’s Oldham is the first permanent building anywhere to use tulipwood CLT, CNC-fabricated at ZÜBLIN Timber in Germany. As a hardwood that is often used for the non-visible parts of furniture, the timber combines robustness with a striking visual appearance. dRMM first developed the material in collaboration with Arup and the American Hardwood Export Council for the 2013 London Design Week ‘Endless Stair’ installation, sited temporarily in front of Tate Modern.

Off-site and modular construction

About the author

Over the past few years there has been an increase in mass timber fabrication processes being set up in the UK, particularly with the import of computer numerical control (CNC) machines – used for cutting and profiling for crosslaminated timber (CLT) panels. Modular factories have led the way in this, with several having emerged recently to serve development projects nearby. This is a step change for the construction industry. These modular producers employ production lines that are not dissimilar to those of car manufacturing plants, with large hulks of pre-finished building moving through the factory to emerge ready to be delivered to site and installed in location. By employing just-in-time delivery processes, modular construction methods are well suited to tight urban sites and fast construction programmes, and are likely to lead the way with improving productivity across the construction industry. For many reasons, engineered timber is a natural bedfellow with modular construction. The design of modular buildings tends to follow a systems-led approach, using a kit of parts that are stacked and repeated for maximum efficiency. The automated fabrication process of CLT has long been famed for achieving a tolerance of mere millimetres, and this combination of engineered timber and the production line assembly process allows for a high-quality product with less production wastage and greater efficiency.

Better-quality buildings While mass timber modular systems are still in their infancy in the UK, timber construction of all forms is well suited to take advantage of the movement away from materials reliant on mineral extraction and chemical processes towards a cleaner, healthier approach. Public awareness of the lifetime impacts of materials appears to be increasing, and timber is the ideal material to address these concerns. Coupled with the emerging trend of off-site and modular systems, there is a profound possibility of linking the current public perceptions around material sourcing, health and wellness with producing better-quality buildings that are made faster and cheaper than the current alternatives. n

Timber structures Off-site construction

“The social aspects of off-site timber construction are not limited to the built system, with the factory environment offering clean, safe places of work capable of providing improved job security and flexible shift patterns.”


lobal construction is on an upward trajectory with a predicted output of $15.5 trillion worldwide by 2030 despite its inherent productivity challenges.1 Unfortunately, given that around half of all non-renewable resources mankind consumes are used in construction, this is likely to exacerbate its negative environmental impact, making it one of the least sustainable industries in the world. The amount of time we spend in the built environment ranges from 80% to 90%2 and ensuring that the built environment is healthy and is delivered responsibly is a major challenge. Off-site timber construction is well positioned to be the clean technology solution to this challenge.

Manufactured timber The creation of a sustainably built environment at the required level of productivity necessitates a manufacturing approach. It needs to be resource efficient, with timber being the natural choice given its ability to sequester carbon and produce energyefficient building envelopes that can be repurposed at end of life. Beyond the aesthetic appeal of timber there is evidence demonstrating that timber buildings are inherently healthier places to live, with several studies revealing a positive impact on occupant stress levels when the material is left exposed.3 >>

The role of cross-laminated timber Maggie’s Centre in Oldham is the world’s first hardwood cross-laminated timber building and is a great example of timber being used within a healthcare building in the UK. The American Hardwood Export Council (AHEC) supported this project and its creation was informed by previous pilot demonstration projects for the London Design Festival, ‘The Endless Stair’ and ‘The Smile’. Technical information was extrapolated from these sculptures to inform building design. Most recently, AHEC has partnered with Waugh Thistleton Architects, Arup and the Construction Scotland Innovation Centre to design and manufacture ‘MultiPly’. Glenalmond Timber in Scotland pre-processed the material and Edinburgh Napier University conducted all the necessary quality assurance structural test work. The objective of this 2018 London Design Festival project was to demonstrate innovate methods of modular construction with a view to future uses in off-site manufacture.

Timber structures Off-site construction

Building the construction workforce of the future The social aspects of off-site timber construction are not limited to the built system, with the factory environment offering clean, safe places of work capable of providing improved job security and flexible shift patterns. This type of work environment improves workforce diversification and allows the implementation of improved career pathways. The workforce of the future may be less interested in a career on a cold, damp construction site working in an adversarial framework. The next generation can, however, be inspired towards a career in manufacturing, particularly when it offers the opportunity to deliver a more sustainably built environment. The skills required for this will be different to the skills used in current construction practice, with the need to develop more holistic knowledge sets. Workers will also need an improved understanding of project management, scheduling and planning requirements, all geared towards efficient delivery. On this basis, Edinburgh Napier University has established the Built Environment Exchange (beX). beX is a platform approach to accelerating change in construction culture, developing dynamic talent and delivering experiential learning and funding opportunities for students. Created to address the challenges of the construction sector, which is adversarial by structure, overly complicated by design and flawed on delivery – ‘snagging’ as it is universally known, beX offers an alternative collaborative approach to education capable of harnessing top talent and providing the skills needed to deliver a more sustainable built environment. One of the activities was a joint learning week with Harvard Graduate School of Design (GSD) students visiting timber industry partners in Scotland.

Digitisation and economic advantages In the future, a digital thread will be capable of running from forest floor to built solution. This digitisation of the built environment is happening in what is regarded as the fourth Industrial Revolution. Buildings will become intelligent assets, creating new opportunities for innovation. Offsite timber construction is well positioned for this modern context given the sector’s early adoption of enterprise resource planning, computer-aided design and computeraided manufacture. Building Information Modelling (BIM) will facilitate the interoperability and visualisation of these processes, as well as the further augmentation of structure, thermal and environmental performance content. Harnessing digitisation will present the opportunity to better demonstrate the holistic value proposition of off-site timber construction and its sustainable credentials socially, environmentally and economically. The economic arguments do, however, need to be better structured. There are wider economic impacts to be created through improved upskilling pathways for localised labour adding value to localised supply chains. The economic advantages that can be gained through enhanced levels of productivity improving construction delivery programmes and corresponding financing costs need to be better evidenced. The whole life cycle cost of off-site timber construction must be demonstrated given its ability to reduce the performance gap in terms of less standard deviation, addressing built-as-designed and better assurance towards the fabric performance.

Performance requirements Regulations have in many respects helped to move the needle on off-site timber construction uptake. Environmental and energy performance requirements are now more easily ascertained relative to traditional forms. Higher levels of insulation, airtightness and reduced cold bridging, combined with limited embodied carbon as standard. Regulation will largely drive future performance requirements and, with enhanced levels of post-occupancy evaluation going forward, captured via a feedback loop to the digital model, the evidence base can be created. Performance in fire has often been a limiting criteria, particularly when considering medium to high rise. The recent UK Government consultation to consider banning the use of combustible materials in the external walls of high-rise residential buildings following the findings of the Hackitt Report4 was an example of this. The outcome of this type of process could undermine the strides being made >> Timber 2019 Industry Yearbook

in this segment of the market, largely driven by engineered and mass timber products. Going forward there is therefore a need to ensure the information from available research and the growing number of successful test cases of timber highrise systems is captured and used to best effect, ensuring any future regulatory changes are influenced by a robust evidence base.

Structural challenges The resilience and robustness of structural timber systems is worth exploring with respect to climate change. More extreme weather conditions will have to be accounted for going forward, affecting both structural and thermal requirements. For example, higher winds place more demands on system stability, particularly for taller structures, and more extreme temperatures and humidity levels will necessitate changes to the climate control of buildings. Innovations in timber connections, combined with engineered timber products and the use of analytical design approaches, such as Eurocode 5, and software simulation models with finite element analysis capability, can help overcome such structural challenges. Timber can also assist with moderating the internal environment – exposed timber can provide moisture buffering as a result of its hygroscopic nature. As a material, timber has a better a strength-to-weight ratio than many other materials used for structural purposes, which www.trada.co.uk

helps reduce foundation requirements and improves logistical operations, for example by reducing transport carbon emissions and extending the allowable reach of cranes onsite. Light weight does mean lower thermal mass, however, but thermal mass can be achieved as necessary through the use of solid laminate timber systems (glued and non-glued), and combining timber systems with other higher density materials such as concrete (for example, timber-concrete composites), or via the inclusion of smart or phase change materials.

Design life and sustainability There will be a growing emphasis on design skills to deliver such holistic solutions while ensuring compatibility with manufacturing, logistical and assembly arrangements. Design for manufacture and assembly and disassembly (DfMA+D) will ensure that material utilisation will be maximised throughout the whole life cycle. Upon disassembly, the timber resource can be upcycled into new engineered products, thereby further extending the sequestration of carbon while providing continued economic benefits. Ideally the wood will be burned at the end of life to create biomass energy, or biomass energy will be created as by-product of the manufacturing process. It is worth noting that material waste from construction and demolition waste accounts for approximately 25% to 30% of all waste generated in the EU; however, removing construction to factory environment results in material optimisation yields of 98% (that is, 2% waste).5 >> Timber 2019 Industry Yearbook

Timber structures Off-site construction

Material utilisation will be key in the future, as will sustainable forest practices, given that the increase in timber use will put further pressure on the supply chain and available resources, leading to rising demand, with new uses having the potential to significantly affect price. It will therefore be necessary to add value to the local UK resource to complement what is imported. According to the WWF, ‘sustainable timber markets are a means to mitigating and adapting to climate change, which has significant implications for the global economy’ (see ‘100% Sustainable Timber Markets: the Economic and Business Case’, www.wwf.org). Combining environmental and economic benefits in this manner is compatible with the paradigm of the circular economy. Improving productivity, reducing cost and limiting environmental impact is regarded from an industrial perspective as clean technology.

Off-site timber technology Internationally, there is growing recognition of clean technology, as exemplified by a Scottsdale, Arizona-based start-up Katerra – a company believed to be valued at more than $3bn. Founded in 2015 by Michael Marks, ex-CEO of technological manufacturer Flextronics, Katerra is a technology-driven company set up to defragment the delivery of buildings to provide cost-certainty with environmental efficiency.

Conclusion The challenges and opportunities for off-site timber construction are plentiful, and it is clear that with continued innovation it has the capability to respond to the varying and complex factors required in the delivery of a sustainably built environment. The evidence base for this will also continue to grow with more examples taking shape on the basis that ongoing threats do not undermine its potential. Timber’s attributes as a modern building material alongside the onset of digitisation and continued research will enhance this further. The use of off-site timber construction to deliver the built environment therefore responds to the need to be more resourceful while being adaptable to future climatic conditions. Its compatibility with the circular economy is apparent and its ability to offer a holistic environmental solution makes it the forerunning clean construction technology. n www.trada.co.uk

Is it time to swallow the off-site pill? Katherine Wade and Oliver Neve assess the declining health of the construction industry, and offer some medication for its recovery.


he threatening title of the 2016 Farmer Review of the UK Construction Labour Model, ‘Modernise or Die’, was a stark prognosis for the construction industry likened to a sick or dying patient. The review, commissioned to evaluate the industry’s current and future state, recommended a shift towards pre-manufacture approaches and away from the deep-seated traditional methods. Within a reactionary industry, with little incentive to change, trends such as pre-manufacture or Design for Manufacture and Assembly (DfMA) should be encouraged as they could be the medicine required to relieve or even cure the symptoms of the deteriorating industry.

The Farmer Review of the UK Construction Labour Model: Modernise or Die

The patient There is much uncertainty over the availability of the future construction workforce due to the UK’s impending exit from the European Union. Migrant labour currently accounts for half of the London workforce in the construction industry1, which makes for uneasy reading. In fact, in the UK as a whole, the decline in the available labour force within the next decade can be expected to be 20–25%2, critically undermining the ability to deliver the infrastructure expected and required by other industries to operate. In the housing market specifically, the ageing workforce will be under increasing pressure to produce a growing number of houses. A chronic shortfall of new homes can be expected.

Just what the doctor ordered An antidote to this uncertainty lies with processes such as DfMA, which rely far less on a full site team for the erection of a structure and instead rely increasingly on machinery and technology. Pioneered in the 1970s, optimisation studies were carried out to simplify designs. Numerous industries currently adopt DfMA processes with undeniable success: from Boeing, Hewlett Packard and Ford to many toy manufacturers. This poses the question why the construction industry has not been nearly as receptive to the concept. The answer is probably the stigma attached to the portacabin classrooms that lacked character or thermal control and were merely a product of an excess of factory capacity and available techniques Example of DfMA, www.machinedesign.com following World War II. Since the days of the portacabins, particularly in the past decade, processes and machinery have significantly advanced, and the focus is now on innovating materials to match these technological advancements. Exploration into the use of larger format materials with fewer connections and hence fewer opportunities for error, such as prefabricated cross-laminated timber (CLT) panels, could be the next step towards holistic pre-manufactured design.

Timber structures Off-site construction

Miracle cure Originally, CLT was associated with in-situ construction techniques, which are reliant on site operations and conditions. The industry has since progressed to a hybrid state of using both in-situ techniques with some prefabrication. The obvious evolution is therefore pure prefabrication in controlled factory conditions, with a small number of companies already venturing down this path. The benefits of modular CLT construction are plentiful. Total construction time is shortened but, crucially, time on site is shortened, too. A key advantage of DfMA is therefore reduced health and safety risks during construction, both in factorycontrolled conditions and on site. The nature of traditional on-site construction results in a large scope of opportunity for accidents to occur; use of tools, machinery and site equipment in an uncontrolled environment is difficult to manage and regulate. Conversely, being under factory conditions for fixings, installation and processes, in a controlled environment with standardised procedures, reduces the chance of an accident occurring.

life cycle of the material. Once occupied, CLT modules exhibit impressive energy efficiency due to the airtightness of the structure ensured in factory conditions.

Not only is modular CLT housing an exciting new benchmark, it also has the potential to be applied across a range of typologies including hotels and student residences. This is not to say that the housing typology has reached its full potential. The production line format has the capacity to intertwine with the escalating world of digital design, using parametric tools to prioritise and optimise aspects of the design. n

About the authors

The urgency for more social housing programmes also features in the Farmer Review. Prefabrication streamlines processes resulting in cost efficiency, while consistency in quality can be expected from controlled factory conditions compared to weather-dependent site work.

The production line environment also lends itself to exciting new realms of housing possibilities: customisation of modules including specifying finishes and even room arrangements can be programmed into the production line for new home buyers. The compact programme permits the involvement of buyers and future investors. There are also environmental benefits of CLT: its sequestration of carbon results in approximately half of the CO2 emissions of an equivalent concrete structure when considering the full

The challenges of building defect-free homes Off-site construction can contribute to improvements in delivering better quality buildings, says a report that calls for urgent changes in the culture and processes of housing construction. Ron Alalouff reviews its conclusions.


he Housing Forum brought together experts from across the supply chain to consider the main risks of current methods of developing and refurbishing residential property. Its conclusions cover the whole process from project set up to handover on completion. The report ‘Stopping Building Failures’ The Housing Forum, 2018) identified several key problems: • regulations and guidance that are complex and unclear • a lack of clarity around roles and responsibilities • a race to the bottom in procurement. The Housing Forum study is centred on three key areas: • procuring for quality • harnessing innovation to prevent defects • building defect-free homes.

Procuring for quality: the recommendations Under procuring for quality, recommendation 1 is that projects should be set up to reflect clear value judgements linked to initial cost plans. This ‘vision’ should include aspirations for development, profit and contingency that must be agreed at the outset by the entire project team and should be a ‘golden thread’ that ties in initial (and costed) quality aspirations right through to delivery. Recommendation 2 says clients should procure projects using contracts that support integrated teams, promote value and develop tight performance specifications. This includes adopting fair, simple and transparent procurement processes and enabling early contractor involvement in design, using tender processes that help meet project objectives. The focus is on quality and how it will be delivered, incorporating more prescriptive specifications to avoid a drive down to minimum standards. Recommendation 3 urges industry and clients to work together to develop new materials, techniques and training, to help clients gain a better understanding of the appointment and briefing process. Recommendation 4 calls on the insurance sector, construction industry and government to work together to further develop integrated project insurance procurement, as a means of driving integrated teams and project efficiencies, and to provide sustainable financial margins for firms. Recommendation 5 urges the wider adoption of Building Information Modelling (BIM) to provide a continuous record of decisions, actions and transactions throughout the project, to enable improved co-ordination and provide the opportunity for better facilities management and collaboration.

Key to the timber construction sector is recommendation 6, which calls for early consideration of how Design for Manufacture and Assembly (DfMA) and modern methods of construction can be used to reduce workload and improve productivity and safety on site.

Timber structures Timber frame

Defect-free homes Critical changes that would improve quality assurance processes on site include: • Greater emphasis and training for on-site inspection

methods, particularly for those managing construction projects (recommendation 7).

• More use of clerks of works to provide impartiality and

a quality safety net; more funding to train people for this profession (recommendation 8).

‘Pervasive reports of building failures in both new build and refurbishment and maintenance of existing stock are undermining consumer confidence. In an era when large housing associations and councils Timber roof being lifted into place will be embarking on major housing construction projects ... it is essential the housing construction sector addresses and resolves the issue of quality.’

• Greater use of technology to document construction quality,

Commenting on the report, Nigel Ostime, Project Delivery Director at Hawkins/Brown, said improvements in quality and productivity can be significantly enhanced with off-site manufacture, including the use of timber frame and CLT.

• Clients making the development of skills, such as the training

‘The report sets out 14 recommendations running through the whole project process. A key message is the need for procurement reform, without which it will be difficult to effect change, and in particular the need to design for manufacture and assembly rather than traditional construction. It also highlights the benefits of modern methods of construction and greater use of off-site to improve both quality and productivity. This includes timber frame and cross-laminated timber, which also have benefits in reducing carbon.’ n

such as the use of tablets and software on site; BIM and imaging and sensors to provide evidence that work has been completed to standard (recommendation 9).

of apprentices, part of the selection criteria to help plug the skills gap (recommendation 10).

• Greater clarity about project team roles including the role of clerk of the works to maintain the golden thread of project quality (recommendation 11).

• Greater use of pilots or benchmark samples/mock-ups to assess quality of workmanship when choosing suppliers (recommendation 12).

Longer-term recommendations The report calls for tighter controls on the competencies of the workforce to raise quality. This includes mandatory licensing of people working in life-critical trades, such as passive fire protection and structural systems, and over time, the widening of this requirement to other construction trades. Key to a better inspection regime would be the introduction of ‘hold points’ in the construction process, whereby critical stages would be checked and verified by independent quality inspectors before further work can proceed. This could be tied to the payment process for the main contractor and sub-contractor. ‘The tragic events that unfolded at Grenfell Tower have brought failings across construction into even sharper focus,’ says the introduction to the Housing Forum report. ‘What has become clear is an urgent need to change culture and processes. Grenfell will be the catalyst for changes that many in the sector would say are long overdue. But alongside the regulatory reforms that must ensue, how can we bring about a muchneeded culture change so that all homes get built the way they are designed, to the highest quality standards? www.trada.co.uk

Site checking to ensure high-quality work While modern timber frame buildings are usually factory made, a successful project still requires every aspect of the on-site construction process to be completed to high standards of workmanship.


ite check: The timber frame pocket guide equips site managers and other construction professionals with a reliable resource to supervising and checking subcontractors’ work.

The wiro-bound book has colour-coded sections for each stage of the construction process, and summarises core activities in a checklist format, concentrating on the most important aspects needed to complete the construction process successfully.

Substructure Getting the location and level of the foundation right is one of the most important parts of the process, so it is essential that the tight tolerances required are understood. Poorly laid and inaccurate substructure can lead to other problems further along the build process.

Materials used for levelling sole plates may not be adequate for load transfer. Full support must be provided before construction proceeds beyond ground floor wall panels.

Delivery and storage Materials should be delivered to site ‘just in time’ to minimise the likelihood of damage and ‘double handling’. Panels and ancillary components should be checked against specification to ensure that everything ordered has been delivered and is in a satisfactory condition. Storage tips include: • storing components on level bearers off the ground, ensuring that no panels are distorted • covering the components loosely to protect from moisture, while allowing ventilation.

Sole plates Sole plates must be correctly installed. The setting out and fixing of sole plates can influence the performance of the whole building. Therefore, accurate location, adequate bearing and specified fixing are all crucial. Where packing under a sole plate is required, the option used should be specified by a structural engineer. Common methods are: • permanent structural packers under the sole plate • structural grout under the sole plate. Image 7 - Permanent structural packing under sole plate

Components should be stored off the ground and covered loosely to protect the timber from moisture

Walls All wall panels should be square and dimensionally accurate before following the fixing schedule prepared for the site. The structural engineer’s specification should be followed in all cases; if there is no specification provided, one should be requested. Temporary bracing should be used to maintain alignment of the assembled components. Out of square panels should not be used, as this can cause the overall length of a wall to grow and could lead to wall panels overhanging the sole plates.

Timber structures Timber frame

Cavity barriers need to provide at least 30 minutes’ fire resistance. Elements designed to perform another role – for example, a timber cladding support batten at least 38mm thick – may act as a cavity barrier if suitably located. Cavity barriers should, wherever possible, be tightly fitted to a rigid construction and mechanically fixed in position. If this is not possible, fire‐stopping should be used.

The floor cassette manufacturer lifting method must be followed

Fire‐stopping helps to maintain the fire resistance of a fireseparating element, for example around service penetrations or at junctions with other fire-resisting elements. It should be equal to or better than the fire resistance of the element it is installed against. Fire stopping materials may need reinforcement or support to prevent displacement in the event of a fire. Image 41 - Section of cavity barrier in an external wall

Floors In platform timber frame construction, the floor structure forms an integral part of the building structure, providing horizontal racking resistance as well as tying walls together. Airtightness should be enhanced by using a breathable floor zone air barrier, while floor zones should not overhang into party or external wall cavities or lift shaft/stair openings by more than +/‐10mm.

Breather membrane lapped over cavity tray by at least 100mm Cavity tray Open perpend or equivalent free airflow area Cavity barrier

Breather membrane The breather membrane protects the building from the weather until the cladding is complete, and also provides a second line of defence against wind‐driven rain penetration throughout the life of the building. It is often pre‐installed in the factory, but if applied on-site it should also be fixed and lapped to the manufacturer’s instructions.

Roof framing There are no specific differences in the roof construction of a timber frame structure compared to other types of construction. Any additional roof loads should be tracked down through the building with extra studs. Trusses should be installed and held down according to the structural engineer’s fixing schedule, typically with truss clips.

Cavity barriers and fire-stopping Cavity barriers restrict the spread of smoke and flames through cavities. By closing cavity edges and sub‐dividing large cavity spaces in line with fire-resisting elements, they help to reduce the risk of unseen fire spread. Steel, preservative-treated timber, mineral wool, non‐combustible board and approved intumescent materials can all be used as cavity barriers provided they are of adequate size and comply with the requirements of relevant national standards. www.trada.co.uk

Section of cavity barrier in an external wall

Handover of frame Snagging of the timber frame should be carried out as work proceeds, to ensure the timely handover of the frame and speed of build. All wall panel fixings should be installed as wall panels are erected.

Services installation Notching and drilling of joists and studs can compromise the structural performance of the timber frame, so guidance from joist manufacturers or British Standards should be followed. Cutting, notching or drilling the top and bottom chord of engineered timber joists should be avoided, as this will weaken the floor joist. The order of work must be considered when installing services. Insulation and/or dry linings must not be exposed to the weather, and differential movement must be considered internally when services rise over several storeys and are vertically rigid. >> Timber 2019 Industry Yearbook

Insulation/vapour control layer

Party floors, ceilings and walls

The location and type of insulation must be suitable for use with timber frame, and any gaps or uninsulated areas can reduce the thermal performance of the building envelope. Insulation will be specific to each project and must be carried out according to manufacturers’ guidance.

The acoustic performance of party walls and floors depends on both specification and workmanship, and separation of party wall leafs and floating floor perimeters are paramount. Particular care should be taken at wall/floor junctions, as air paths reduce acoustic performance and can compromise fire resistance.

The durability of a structure is ensured by keeping the timber dry. In most timber frame walls, this is achieved through a combination of a vented cavity between the frame and the external cladding and a protective breather membrane on the ‘cold’ side of the insulation. The vapour control layer prevents interstitial condensation forming within the wall structure and also significantly contributes to airtightness.

Dry lining Plasterboard wall linings help to provide fire resistance and acoustic performance, so correct specification and fitting is critical. Fitting should not occur until the frame is watertight and the timber has been checked to ensure it contains less than 20% moisture. Plasterboard should not be installed Image 62 - Junction of party wall before services in walls have been tested.

Air movement in party wall cavities can lead to significant heat loss and result in what is known as party wall thermal bypass.

Damp‐proof courses Damp‐proof courses (DPC) prevent moisture transmission by separating timber from materials that could transfer moisture to it. DPC cavity trays should be lapped to deflect moisture away from the timber, and windows and doors should be sealed to the timber frame via a DPC to help maintain a weathertight seal. >>

Cladding Providing a drained and vented cavity between masonry cladding and the timber frame structure is vital to ensure the latter’s longevity. Masonry cladding should be constructed using a coursing rod to ensure the right levels are achieved at the openings and eaves levels. The coursing should be pre‐planned to allow for a clearance between elements such as window sills, soffits and balcony structures for differential movement. Other types of cladding, such as wood, lightweight render and metal are sometimes preferable to masonry cladding.

The implications of differential movement are: • Any material or component attached to the timber frame structure that overhangs or projects through masonry cladding must have an adequate gap beneath it to allow differential movement to take place, without damage to the structure or the cladding. • Differential movement is cumulative with masonry cladding and gap sizes should increase with height.


• For services and cladding supported off the timber frame, differential movement should be detailed locally at floor zones.

Labour, materials and access for roofing should be available in good time and the correct specification of roof membrane, adequate ventilation and roof tile overlap should be ensured.

Vertical shrinkage can be reduced by: • using I‐joists, open web joists or super‐dried timbers

Differential movement

• ensuring detailing is correct to allow for settlement

As timber dries out, its cross-section shrinks and the structure settles, so allowances must be made for this movement to avoid damage. Adequate gaps for movement and any compressible filler material should be provided between window sills, roof structures, services and self‐ supporting masonry cladding. Floor zone movement joints in lightweight cladding systems should be considered, as should plasterboard linings that span floor zones. It is good practice to pre‐load the timber frame structure with roof tiles and internal sheathing materials prior to the installation of the masonry cladding, within structural limits. If this practice is adopted, specified differential movement gap sizing should not be reduced.

“There has been a gradual shift from traditional wood preservation to wood protection, which is based not only on the inherent characteristics of the wood itself but also on design, maintenance, exposure and moisture risk.”


imber in construction has undergone something of a renaissance, led by the desire to use more environmentally friendly materials and to reduce construction costs. The development of modified wood and engineered timber, such as glulam and crosslaminated timber (CLT), provides new ways of achieving modern construction goals over a reduced construction time. Compared to aluminium, steel and concrete, most timber is produced using considerably less energy and acts as a carbon sink, reducing CO2 emissions.1 While timber is at risk to biological decay, a combination of appropriate design and material selection will mitigate this risk. National and European projects such as WoodBuild, PerformWood and DuraTB have increased our understanding of the performance of wood in service. This has led to modelling of products during their service life, as well as providing guidance for avoiding risks of decay often associated with prolonged exposure to high moisture levels. Another study2 shows that the use of mass timber construction, such as CLT, led to lower on-site labour costs, a lower environmental impact and the possibility of improved amenity and reduced running costs for owners and occupiers.

Service life The importance of service life is highlighted in the Construction Products Regulation, with its seven basic requirements that should be met by construction products during a ‘reasonable service life’. They are: • mechanical resistance and stability • safety in the case of fire • hygiene, health and the environment • safety and accessibility in use • protection against noise • energy economy and heat retention • sustainable use of natural resources. The performance or service life of wood products is based on a combination of end use and degrading parameters. The concept of ‘use classes’ is related to the susceptibility to >> www.trada.co.uk

biological attack of an element and depends on differences in exposure environments. Use classes are further defined by the time wood is exposed to high moisture levels (often defined as levels of 20% or above).

Outer Bark Inner Bark

Similarly, the design of timber components and structures plays an important role in service life. For example, service life increases when avoiding ground contact, covering end grains and avoiding moisture traps.

Standardisation In Europe, CEN/TC 38, Durability of wood and woodbased products, aims to progress standards for wood preservatives and preservative-treated wood, modified wood and untreated wood. It is developing terminology, analytical methods, biological tests, classifications and specifications in accordance with market needs and European regulations. Its objectives include ensuring quality and satisfying consumer expectations, eliminating trade barriers, harmonising methods used in wood protection and promoting sustainable development by delivering reliable wood products. This has helped lead to a gradual shift from traditional wood preservation to wood protection, which is based not only on the inherent characteristics of the wood itself but also on design, maintenance, exposure and moisture risk. In most countries, building regulations and building control systems govern the fire safety aspects of structures. Meanwhile, ten main Eurocodes and subsequent sub-codes provide a common approach to the design of buildings and construction products, with Eurocode 5 being directly related to timber.

Life cycle Life cycle analysis addresses the entire life cycle of a product and a wide range of environmental impacts, avoiding ‘problem shifting’ – for example, from one life cycle stage to another or from one environmental compartment to another. Service life prediction aims to ensure that the service life of a building will equal or exceed its design life, while taking into account its life cycle costs.

Use classes Biological durability is the key factor determining performance for wood in different use classes. The robust laboratory and field test methods that exist make it possible to assign a durability rating (from non-durable to very durable) to timber linked to the intended use class and assuming a worst-case scenario. www.trada.co.uk

The heartwood of timber

EN 335:2013 classifies wood into five durability classes for heartwood of timber species, from “non-durable” to “very durable”, and the natural durability of a wood species can vary widely. The use of heartwood from more durable timber species, wood preservatives or modified wood can also improve the service life of outdoor products. Despite these, better design must also play a part in ensuring their satisfactory service life. While timber indoors (use classes 1 and 2) would normally be dry, care must be taken during construction to ensure that elements are kept dry or allowed to dry. Internal timber should also be protected from interstitial condensation, such as moisture from wet rooms, or from poor design such as moisture ingress through building elements. Larger elements, for example CLT and glulam, are more susceptible to long-term moisture effects. The risk of decay in these larger elements suggests that the use of preservative treatment or monitoring combined with early warning systems can help ensure their integrity. Preservative treatments could be done ‘in laminae’, prior to the manufacture of CLT elements.

Actions and outcomes Over the past four years, a European Commission funded programme or COST Action, FP1303 Performance of bio-based building materials, has engaged more than 260 scientists from various fields in meetings, conferences, training schools and short-term scientific missions on the following themes: • moisture interactions • performance and maintenance of bio-based building materials influencing the life cycle and LCA (life cycle analysis) • performance testing and testing methodologies >> Timber 2019 Industry Yearbook

• LCA of wood modification processes • hygrothermal performance of buildings and their materials • design, application and aesthetics of bio-based building materials • building with bio-based materials: best practice and performance specification. One outcome of this was a project to collect performance data under climatically different exposure conditions using a specially constructed test table.3 Weather data from the test sites was used to establish relationships between climate conditions and the following regularly determined measures: • decay • discolouration • development of mould and other staining fungi • corrosion of fasteners • formation of cracks • moisture performance. A total of 28 research institutions and universities from 15 countries took part in this assessment.

Conclusion The ability of timber to act as a carbon store during its service life provides a feasible low-carbon construction material. The development of new treatments such as wood modification – as well as an increased use of engineered wood products such as glulam and CLT – provide ways of fulfilling modern construction needs over reduced construction time. It is also evident that

a combination of correct material selection and design meeting use requirements can lower the risk of biological decay. Increased understanding of performance in service has led to modelling of products during their service lives, as well as providing guidance on avoiding decay risks. While work is ongoing in these areas, it is hoped that developments will continue to advance opportunities for timber, and in particular engineered wood products, to meet modern construction needs. n

“In a well-managed environment where workers are properly trained and guidelines are followed precisely, the risk of injury is minimised.”


russed rafters, or roof trusses, probably aren’t the first thing that comes to mind when you think of off-site manufactured products. Spandrel panels and metal web joists – common stablemates of trusses – don’t see much of the limelight, either. Despite languishing in the shadows, these products are becoming increasingly popular with housebuilders. Always produced using the latest timber technology, they are designed and manufactured on a bespoke basis.

Collaborative working Best practice in trussed rafter roof construction dictates that everyone involved with the design, manufacture and installation of the roof’s components must work effectively together. Typically, the first step in the process is for the building designer to provide a design for the roof. This is passed to the trussed rafter designer, who then produces a two-dimensional trussed rafter design. Trussed Rafter Association (TRA) members use the latest software to design trussed rafters to comply with BS EN 1995-1-1 (Eurocode 5).1 The trusses are also fabricated in accordance with BS EN 14250.2 Once the building designer has checked the trussed rafter design for structural compatibility with the roof design, production can begin.

Spandrel panels and gable wall panels Spandrel panels and gable wall panels offer an alternative to traditional masonry gable ends and separating walls within roof spaces. These panels are also manufactured off-site, bringing with them a range of benefits: • improvements to on-site safety, as pre-manufactured panels reduce the need for working at height on site • faster installation times, meaning lower costs • little or no waste left on site • using off-site manufactured products can help to address the shortage of on-site skills. >> www.trada.co.uk

Results from a National House Building Council survey found that 17% of 8,000 sites where new homes are being built were already using spandrel panels. This confirms the commitment many housebuilders are making to off-site construction.

Safety first approach Once trussed rafter designs are confirmed, the manufacturing process begins – and so does the issue of health and safety. As is the case for all timber product manufacturers, the machinery used to produce these products can put workers at risk of injury. It’s something the TRA and its members are never complacent about. To manage this risk, the TRA works closely with the Health and Safety Executive (HSE). Most recently, this has involved reviewing the trussed rafters section of the ‘Health and safety in roof work’ guidance produced by the HSE. In addition, the TRA has published several guidance documents (www.tra.org.uk/technical-advice-downloads) for its members, including risk assessments and safety guides for all equipment used in manufacturing trussed rafters, spandrel panels and metal web joists. During the manufacturing process, the dangers facing workers can include: • the loss of fingers or limbs • damage to hearing and eyesight • slip and trip hazards • falling from height or products falling on workers • the presence of wood dust. These hazards are undeniable. But in a well-managed environment where workers are properly trained and guidelines are followed precisely, the risk of injury is minimised.

Haulage policy Loading and unloading trussed rafters presents a significant risk to workers, too. The TRA and HSE joined forces to create a health and safety policy for the loading, haulage, delivery and on-site installation of trussed rafters. Safe haulage begins with the truss fabricator, who is responsible for loading the trusses on to its own vehicles or those of a competent and trained haulier. Before loading, the truss fabricator must make the contractor aware of the size and weight of the load, which should adhere to company policy. Banding is discussed with the driver at this time, to make sure they fully understand the different band colours used to hold together the packs of trusses and those used to secure the packs to the vehicle. This ensures that only the bands being used to secure the packs to the vehicle are cut when the trusses are offloaded. A lift planner should be consulted for any extra requirements or specific load details before the trusses are sent out. All TRA members have designated loading areas within their yards, providing ample space with no overhead cables and clear separation from pedestrian walkways. Members also ensure all those involved in loading have been appropriately trained.

Health and safety notices are essential to maintaining a well-managed working environment. Photo: Pasquill


The trailer used for loading must be suitable for the weight, windage and stability of the trusses so they are safe in transit. The trusses should be loaded against the centre bar to enable even distribution and tight packing. The load should be supported by the forklift or side loader while strapping is secured. This is a critical point in the loading process and loaders should only access the lorry bed if they are completely aware of the company policy in place to protect their safety. >> Timber 2019 Industry Yearbook

| 79

The loader must check the loading sheet before the lorry can leave. Photo: Pasquill

Usual access is via the deck of a modified loader or aircraft steps. Under no circumstances should the loader ever be directly under the extended forks.

Ahead of the driver arriving, the contractor will have cleared the area to provide ample space, making sure there are no overhead cables and that the area is both level and dry.

Once safely on the lorry bed, the trusses can be secured. Each pack should be secured to the centre bar at a minimum of two points above the centre of gravity to avoid trusses falling during transit. The rope or banding used must have a minimum 450kg breaking strain.

Load information, in terms of quantities, weights and sizes, is always provided ahead of delivery so site staff can develop a safe unloading and handling plan. This includes an assessment of the mechanical handling equipment needed to remove the trusses from the vehicle. The contractor must have also considered how the trusses will be stored. As they are made from timber, they cannot be left in an area that is damp or in or near water.

With the roof trusses secured to the lorry, other ancillary items forming part of the order can be added. The driver is responsible for checking the load and will fit transportation straps to ensure that the structural integrity of the trusses is not compromised during transit. This should also take into account any heavy breaking or travelling over rough ground. The designated haulier must be trained in transporting roof trusses and be fully up to speed on the relevant health and safety requirements. Careful management of the loading process in the fabricator’s yard will mean nobody needs to access the lorry bed during unloading at site.

Once the area is clear of other personnel, the driver can release the transport straps. At no point should anyone stand between the unloading equipment and the trailer. It is the responsibility of the equipment operator to ensure no one is in the danger area before attempting to take the weight of the trusses. The driver will then cut the banding securing the pack of trusses to the vehicle. This must be done at a safe distance using a telescopic cutting staff. The forklift or telehandler can then lift the trusses and place them in the designated offloading area.

Once the haulier gets on site, safety is the contractor’s responsibility. However, the delivery driver is well within their rights to refuse to offload the trusses if they deem it unsafe.

TRA members can advise on other procedures, such as using a crane to offload trusses or unloading inverted trusses and turning them around. It is essential that the truss fabricator >>

and the contractor work together to ensure the safety of all involved and minimise the risk of damage to the roof trusses as they are loaded, transported and unloaded.

Installation guide The final stage to consider is the installation of roof trusses. To tackle this, the TRA’s Health and Safety Committee collaborated with safety partner, Paramount Safety Systems, to produce an installation guide (www.tra.org.uk/technical-advice-downloads/ trussed-rafters), which is intended to assist sub-contractors and installers to develop their own site-specific safe system of work. The guide’s mantra is ‘if you fail to prepare, you prepare to fail’. Before installation begins, the following actions must be carried out: • check and read all assembly drawings and information provided by the truss supplier • ensure all personal protective equipment is worn and correctly fitted • ensure scaffolding is in place and signed off • a safe working platform within the structure is strongly recommended • ensure hop-ups and scaffolding edge protection are in place • after reading the truss layout drawings, identify the easiest starting point using the simplest of roof trusses. Once the working area is prepared and safe, the truss pack can be craned in and braced. The trusses can now be released for installation. Lower bracing is fixed, and to allow high-level bracing to be fixed without injury, safe and secure temporary access must be installed. n www.trada.co.uk

“SIPs are manufactured off-site under factory-controlled conditions and hence provide relatively high levels of airtightness. However, attention to detail and quality of workmanship on site is vital and this is more important than claims about faster build speed.”


tructural insulated panels (SIPs), also known as stressed-skin panels, are the basis of modern aircraft wing structures. Millions of people rely on this approach to fly safely every day, hence it is a well-used and proven technology.

Past: ‘What’s past is prologue’[1] The use of SIPs in construction began in the 1930s. In 1937, the US Forest Service (USFS) built a prefabricated house using SIPs in Wisconsin. The SIPs industry was good at public relations – the experimental house was dedicated by the First Lady Eleanor Roosevelt.

After 25 years of service, the house was inspected and found to be in excellent condition. It endured the severe Wisconsin climate (recorded temperature range 46ºC to -48ºC, with significant rain and snowfall) until 1998 when it was removed to make way for a new and larger building. The USFS research paper1 notes that the panels were designed and maintained to control moisture effects. Architect Frank Lloyd Wright was also an early pioneer of SIPs, using them in his Usonian homes in the 1930s. Although Otto Bayer first made polyurethanes in 1937, further development for use in construction was delayed until after the Second World War – self-sealing aircraft fuel tanks became a key military requirement. >> www.trada.co.uk

In 1947, SIP development restarted when buildings using corrugated paperboard cores were tested with various skin materials. They were dismantled in 1978 and most of the panels retained their original strength except for the paperboard, which was unsuitable for outdoor exposure.

Modern-day SIPs Despite the advantages of these early systems, they were characterised by poor insulation performance. In 1952, Alden B Dow (an architect and student of Wright) addressed this with a new panel design using a polystyrene foam insulation core manufactured by his family’s company, Dow Chemicals. He created the first modern-day SIP. The insulation layer in Dow’s SIPs also helped to align the sheets of plywood in a parallel plane. This created a robust structure without the need for rafters and studs. Unlike their predecessors, the first Dow SIP homes were observed to be ‘draught free, easy to heat in winter and easy to keep cool in the summer’.2 Although SIP systems were also used in homes and apartments in California from 1965, the technology really advanced in the 1970s. While Dow’s homes demonstrated the energy-saving benefits of SIPs, the low cost of energy limited early uptake. Following the 1973 oil crisis and the rapid increase in energy prices, many proved that the concept worked and produced durable, long-lasting homes across many climate zones – first in North America and then Europe. The trend in Europe was further accelerated by the development of the fabric-based Passivhaus standard. In comparison, SIPs are relatively new to the UK. After several SIP homes had been imported into the UK, manufacturing in Britain began consistently around 30 years ago. As well as these independent manufacturers, distributors have also been appointed by large-scale manufacturers to service the market.

Present: ‘Happy the man, and happy he alone; He who can call today his own; He who, secure within, can say; Tomorrow, do thy worst, for I have lived today.’[2] Currently, SIPs take the form of a rigid foam insulating core sandwiched between two structural facings. In the UK, most suppliers typically use the same facing – oriented strand board (OSB). The insulating core material can be polyurethane (PUR), polyisocyanurate (PIR) or polystyrene (PS). Panels with a PUR/PIR core achieve the same U-value over a thinner www.trada.co.uk

Typical SIP made from polystyrene and OSB

cross-section than panels with a PS core. PUR typically transmits about 40% less heat for a given thickness. For example, at a U-value of 0.02 W/m2K, a SIP wall using PUR will be about 50mm thinner than one using PS. The difference of internal floor space or plotting efficiency may be significant to some clients. The bonding of the insulation to the facing material allows the whole panel to withstand structural loads. Problems have occurred with this bond in service resulting in structural concerns. The insulation core of PUR panels is autoadhesively bonded to the OSB facings. The PUR is injected in liquid form into the panel, where it expands, and the panels are held at high pressure, making the PUR foam bond to the OSB. It is generally said that this provides better adhesion, rather than relying on glues used in a secondary process as when using PS as the insulation. There are three options of connecting panels: • OSB thin-spline • mini-SIP spline • dimensional timber spline. A University of Birmingham study indicated that dimensional timber splines perform best in structural terms but give more thermal bridging.3 Another University study suggested that this can represent around 25% of building heat loss.4 University studies4 have shown equivalent levels of heat loss through inadvertent air leakage. SIPs are manufactured offsite under factory-controlled conditions and hence provide relatively high levels of airtightness. However, attention to detail and quality of workmanship on site is vital and this is more important than claims about faster build speed. >> Timber 2019 Industry Yearbook

Benefits The benefits of using SIPs are that they: • provide high strength • have good thermal performance • are suitable for most building designs. Their inherent strength allows them to be used for roof and floor panels, as well as walls. For room-in-the-roof applications they provide well-liked vaulted roof spaces. SIPs provide the capability to span from ridge to eaves with, at most, one intervening horizontal purlin. Thus, simple roof shapes can easily and effectively be covered over in hours – for this reason a SIPs roof is often combined with other build methods. SIPs are also growing in popularity as a wrap-around for structural timber frames, combining this system’s airtightness with the charm of internal exposed beam work. Unlike traditional timber frame, the SIP industry has relied heavily on proprietary code evaluation reports, testing and

accreditations specific to a single approach, many being well-proven since the early 1990s. After various US nonproprietary standards that did not address design properties, in 2009 the US-based Structural Insulated Panels Association partnered with NTA Inc, a product certification agency, to produce the first industry-wide code report. This is available to qualifying SIPA members and the provisions are derived from an engineering design methodology.

Future: ‘Your task is not to foresee the future, but to enable it.’[3] SIPs continue to grow market share and the industry does a good job of promoting itself – ever since Mrs Roosevelt! As well as commercial applications, the system is increasingly well accepted in the self-build market, currently estimated at about 8% market share of the self-build market.5 In addition, SIPs are increasingly used with other building systems as a wrap-around, infill panels and roof panels. >>

The technical development of ‘pure’ SIPs has probably plateaued. There may be insulation improvements, but they approach the law of diminishing returns. Similarly, for instance, non-combustible sheathing materials can be used, but the costeffectiveness of OSB has resulted in limited market penetration. SIPs do not perform well in flood situations as it can lead to the OSB or plywood delaminating. However, recent use of non-combustible sheathing materials, which also have good water resilience, coupled with hydrophobic insulation, such as closed-cell PUR and the sealed nature of a SIPs wall, has demonstrated potential for flood mitigation, although admittedly, so far in a limited number of applications.

Hybrid use Most recent product developments are the result of a hybrid approach as the wrap-around method noted earlier. Most blank panels start their life in a 1.2m-wide format and come in various standardised lengths from 2.4m to 7.5m. Hybrid approaches have taken the width to 3.2m and lengths to 10.2m, but more is theoretically possible. Standard SIPs floors and roofs typically can reach spans of up to 4m and hybrid approaches incorporating timber I-beams have been applied up to 10m spans. Although the standard panel width is 142mm, various thicknesses are available. One of the more recent hybrids using a combination of PUR and PIR, totalling 285mm thickness, offers a wall U-value of 0.08 W/m2K, which is claimed to be the best in the world.6 Usually SIPs are made as blanks and then door or window openings are cut in a subsequent process, often in the factory but sometimes on-site. Pre-fitting of windows and doors in the factory has been seen mainly with hybrid approaches but, although popular with some clients, takes much factory time and space, limiting a wider uptake. With the increasing promotion and interest in volumetric and modular buildings, particularly in the north of England, one future that seems assured for SIPs and hybrid SIPs is their use either to replace light gauge steel frame in such buildings or as infill panels. Another interesting hybrid SIPs-type approach is to integrate CLT with the injected insulation approach, normally PUR, to give robust panels that are particularly suited to commercial building requirements.

Conclusion From a fascinating prologue to an exciting present, SIPs offer the brightest of futures for timber in construction and an opportunity for all involved. n www.trada.co.uk

Timber structures Panel products

“The Panel Guide is a valuable source of information for construction professionals who are specifying or using panel products and also for consumers who only occasionally come into contact with panel products.”


he Panel Guide was first published in 2001 and was written by Prof J Dinwoodie, OBE (Building Research Establishment Ltd), David Duke-Evans (Wood Panel Industries Federation (WPIF)), Dr Victor Kearley (BM TRADA) and Alastair Kerr (WPIF), alongside many other contributors. It has since been reviewed four times, with the last major review in 2014. During the last major review, it was also restyled and the drawings reworked for a more contemporary look.

The 2019 revision The 2019 revision (v4.1) focuses on areas highlighted by industry feedback, primarily on how panel products are used in flooring, and reflects the wider range of products now available. Updates have also been made to align with changes in standardisation. Some of the feedback received highlighted that the Panel Guide didn’t specifically address cassette floors and was also lacking information on common issues faced by the industry, in some cases offering conflicting advice. The revised sections are: • the flooring section • the flat roofing section (to bring them in line with the changes to the flooring section) • the WPIF floating floor industry standard, which is published with the Panel Guide as an annex. The WPIF floating floor industry standard has always been a stand-alone document and gets reviewed by the WPIF technical committee; although it is published with the Panel Guide as one of the annexes, it goes through a different review process. The review of the floating floor annex and subsequent changes have been quite extensive, including re-styling and redrawing the original hand-drawn illustrations to modernise the look of the document.

Flooring Summary of the changes to the flooring section: • nogging requirements • how to deal with panels finishing mid-span • allowable overhang of the panel over the joist at the edge of the room >> www.trada.co.uk

Timber 2019 Industry Yearbook

| 93

Timber structures Panel products

• removal of option to fix panels parallel to joists • clarifying expansion gaps, both intermediate and at the perimeter where the floor runs under the wall • changes to resilient floor underlayment specifications (BS 82031 changes) • new panel products, that is ‘glue-only’ floor systems and weather-resistant panel products.

Noggings The Panel Guide mentions that noggings should be present for square-edge panels used in flooring, but it does not specify dimensions or what is considered suitable. Current practice has been reviewed and, together with recommendations from respected bodies in the industry, a nogging minimum size has been specified that will give the minimum bearing and support required.

the figures in Panel Guide shows panels running parallel to the joists over single spans. These two pieces of guidance were in conflict and the decision was made to remove the figure.

Expansion gaps Panel Guide states that there should be expansion gaps around the perimeter of a room between the floor and the wall. This guidance is applicable for a floor that is laid after the joists have been put down, but is not practical where the floor deck is already laid to the edges of a cassette floor and the wall is to be built on top of the floor. In addition, the guidance (or lack of it) was putting the Panel Guide in conflict with other well-respected industry guidance. So current guidance and common practice have been reviewed, the implications have been considered and the Panel Guide now includes guidance on how this situation should be addressed. The amount of expansion needed in intermediate expansion gaps where there are large or long runs of flooring has also been clarified.

Mid-span finishes One issue raised by industry feedback was what should be done when a panel finishes mid-span rather than on a joist. Although this situation is not ideal, one solution is to use an ‘H’ nogging. Allowable overhang Industry feedback also requested guidance on the amount a panel can overhang the first or last joist running parallel to a wall. This was reviewed and, with the long history of use of this practice, it was decided that the Panel Guide should align with the guidance of the National House Building Council standard, clause 6.4.10, which states: construction of timber floors must ‘have a clearance of 25-75mm between the first joist and the wall face to aid the installation of services and the fixing of floor decking’. Fixing panels parallel to joists The guidance in Panel Guide, and most testing on flooring grade panels, is conducted with panels over two spans because this will produce the strongest deck. However, one of

Resilient floor underlayment specifications BS 82031 was revised in 2017, with the involvement of the wood-based panel industry, and resulted in the tightening of the specification for ‘fabricated underlays’. A fabricated underlay is a panel product that overlays an existing wooden floor, but is the underlay to a resilient floor covering. The Panel Guide has therefore been brought into line with BS 82031 and modified to clarify the terminology around the difference between fabricated underlays and floating floor overlays. This could cause confusion as they both overlay, but the fabricated underlay terminology is born from the floor covering sector so it is considered an underlay in that sector. Guidance for the installation of resilient floor coverings has also been aligned with that of BS 82031. New panel products The final change to the flooring section was necessary due to the prevalence in the market of not just raw uncoated panel products but variants and systems developed as a response to customer requirements. These requirements were for weather resistance during construction, cleaning up floors following completion of the building, plus so called ‘glueonly’ floor systems, which are flooring systems with reduced mechanical fixing requirements that can not only speed up installation but primarily aim to reduce noises that can be present in timber floors. While the Panel Guide recognises that these products are available, it doesn’t give detailed information as each system is particular to a manufacturer. It does, however, serve as a good signpost to those products being available to help the users of panel products choose the most appropriate product for their job.

Timber structures Panel products

Roofing and floating floors Summary of the changes to the roofing section: • removal of recommendation to fix panels parallel to joists • addition of missing guidance for square-edged panels and expansion gaps. Summary of the changes to the WPIF floating floor industry standard: • includes fabricated underlays from BS 82031 • updates to building regulation and standard references • includes new information on floating floors over timber bases • acknowledging the lack of deemed-to-satisfy structural solutions for non-domestic flooring • editorial refinements and streamlining • more information on ceramic tiling to floating floors • review of all technical aspects • modernisation of drawings and format. The roofing section had minor changes to bring it in line with the flooring section, while the WPIF floating floor industry standard went through a major review. Even though the review of the floating floor industry standard was thorough, it wasn’t changed significantly, but was brought into line with current requirements – the most significant change being the introduction of information for the installation of floating floors on to timber sub decks. This was added due to a request from the timber frame industry that this practice was becoming much more common and that some guidance on best practice could be helpful to avoid some of the issues that had arisen – the most common being the sub deck sagging between the joists with the floating floor placed above it. This issue has been addressed with some simple guidance and a new illustration on how to avoid such problems.

Conclusion The review process has strengthened the information contained in the Panel Guide. Not only does it serve as a considered source of information but through periodic review it also has completeness, which is invaluable in answering questions or getting people on the right track when trying to make decisions. The Panel Guide is a valuable source of information for construction professionals who are specifying or using panel products and also for consumers who only occasionally come into contact with panel products. n

Timber structures Fire safety

Addressing the fire safety challenges of ambitious timber structures Danny Hopkin, Stephen Dickson and Michael Spearpoint report.


imber structures are undergoing a resurgence due to their aesthetic appeal, environmental credentials and economic speed of construction. Engineered wood technologies have made timber structures viable in markets that have typically been dominated by steel and concrete. As such, the complexity of schemes for which timber is adopted and the scale of building in which it is used is rapidly shifting.

Fire-resistance concept The burgeoning tall timber market polarises opinion. It can be difficult to dispute the aesthetic, environmental and construction programme credentials. Nonetheless, timber is combustible and the perception of its performance in fire is rooted in a long and distressing history. A century or more ago various ‘great fires’, such as London (1666), Chicago (1871), Baltimore (1904) and San Francisco (1906), all devastated neighbourhoods that were constructed of timber buildings. Because of the destructive aftermath of such fires, building resilience in fire began to enter the consciousness of the world’s developed societies. The need for ‘fire-proof’ materials became apparent, which instigated an important and familiar concept – fire resistance. To assess the veracity of a product’s fire-proof credentials, a consistent means of benchmarking was required – a test (Figure 1). The test that came to define the fire resistance of an element of construction is consistent with that which emerged in a period where fire science was in its infancy. The heating regime (Figure 2) was intended to be more severe than any fire that could be reasonably expected using anecdotal evidence from the fire brigades, who were seen as the authority on fire development at the time. However, shortly after the emergence of the standard fire test, it was quickly appreciated that fires did not behave according to the adopted test heating regime. The work by Simon Ingberg in 1928 led to a concept that allowed real fires to be correlated with the idealised test heating regime according to the nonpermanent fire load (furniture, fixtures, stored goods, etc). www.trada.co.uk

This concept allowed fire-resistance durations (or periods) to be defined according to a building’s use, but on the pretence that the structural frame or enclosure does not contribute to the available fuel. The same principles still define what fire resistance is required for elements of structure in different buildings today, with values proposed in various guidance documents and building codes around the world. Ironically, the standard tests are now adopted to assess the fire-resistant performance of building elements constructed from combustible materials, too. The relevance of fire resistance for timber structures is often debated, what cannot be ignored is the influence that the principle has on design today. >> Timber 2019 Industry Yearbook

of the exposed structure has been shown experimentally to potentially significantly impact fire development and fire severity. In doing so, the core assumptions behind fireresistance periods cease to be valid, with alternative fire safety engineering approaches likely to be the only practical route to compliance with statutory fire requirements.

Modern timber buildings and fire design guidance: a divergence Given the aesthetic qualities of timber, there is often an architectural ambition to have the structural elements expressed. Engineered wood products can provide the visual qualities and durability of traditional solid-sawn timber coupled with a greater strength and reduced production time. Products are composed of boards or lamella bonded together in layers. This approach results in an increased strength over solid timber as imperfections such as knots are not as critical to the product performance. Production times are reduced as it is not necessary to wait for a tree to grow to the same extent as required for a solid timber element of the same dimensions. In addition, engineered wood products can be formed into panels of dimensions not possible using single pieces of sawn timber. Typical engineered wood products include crosslaminated timber (CLT), glued laminated timber (glulam) and laminated veneer lumber (LVL). The traditional treatment of timber in fire is through charring rates, with elements sized to accommodate the relevant load combination after accounting for the loss of material as the timber combusts. Conventionally, a fire-resistance period is defined according to some recognised guidance, for example Approved Document B or BS 9999, and subsequently elements are sized to achieve, for example, 90 minutes’ structural fire resistance. This sequential approach de-couples the design of the structural element from its impact on fire development, essentially assuming that the contribution of the structure to the fuel is negligible. This is in conformity with the original work of Ingberg and the resulting fire-resistance period recommendations found throughout the world. Where the structure constitutes a high proportion of an enclosure’s lining, the de-coupling of the combustion of the structural elements from the enclosure fire environment is, at best, crude, and at worst, dangerous. In such a case, the contribution of the structure to the fuel is no longer negligible. The impact

Timber 2019 Industry Yearbook

The starting point for an engineering methodology for structures where enclosures are formed of exposed timber is an acknowledgement that the status quo approach is inappropriate. There must be cognisance of the impact any exposed timber has on the fire development, and subsequently what measures need to be put in place to ensure the structure has an appropriate likelihood of withstanding the burnout of a fire. However, the underlying principle of designing exposed timber buildings that are resilient to fire is not different from more traditional forms of construction. This is to avoid fire spread beyond the compartment of fire origin and provide enough structural resistance until a full burnout of the fire is achieved. Recently, several projects in the UK have included CLT elements as part of the design of the building structure. CLT is made from planks glued together in layers perpendicular to one another and usually manufactured in large panels several metres in each direction. Various configurations are common such as three, five or seven layers, which can have equal or unequal thicknesses, such that total panel thicknesses can range from 40mm to 300mm. In contrast to solid timber, where the charring rate is taken to be constant through the thickness, CLT panels have the potential for layers to fall off due to delamination/debonding. This is possible if the glueline between layers is subjected to increased temperatures so that there is a softening of the adhesive. If delamination occurs, then an increase in the fire’s heat release rate is likely due to virgin wood behind the delaminated portion being exposed to increased temperatures and subsequently igniting. There are many variables that can influence the delamination of CLT layers such as: • the adhesive type • orientation of the panel • grain direction • timber species • number and variability in thickness of the layers. The delamination mechanism of CLT is still not fully understood and research is ongoing into each of the aforementioned variables. However, it is known that if the gluelines are subjected to increased temperatures, delamination is likely. Hence, a key

Timber structures Fire safety

design principle when analysing the fire resistance of CLT slabs is to try to prevent delamination by limiting the prospect of the char interface (commonly adopted as the in-depth penetration isotherm at 300°C) from reaching the first glueline. OFR Consultants, alongside global research institutes, has developed an engineering methodology that provides a robust basis for the design of exposed CLT structures while acknowledging the uncertainty in the causes of delamination. The main foundation of this methodology is to mitigate the prospect of delamination, thus allowing the char that develops to stay in place and insulate the virgin wood below. If the char layer interface does not reach the first glueline, it is assumed that delamination will not occur. As long as this facet holds true, eventually auto-extinction of the timber can be reasonably expected. This methodology has been applied to UK projects (Figure 3) and uses the latest version of the B-RISK fire zone model developed by BRANZ. This is used to simulate fire development in an enclosure and at each point in time computing the heat flow through exposed internal surfaces. In doing so, the depth of char is computed, with this timber mass added to the available fuel. Depending on the design problem, the designer may choose to place more emphasis on the combustion of the extra fuel, leading to external flaming or a prolonging of the fire’s duration. Once full burnout has been simulated, the depth of char to exposed internal faces is determined, and this can be used to inform what minimum internal lamella thickness might be appropriate to obviate delamination, in the process supporting a greater possibility of the fire undergoing auto-extinction. Further, where depths of char are too deep, and the exposed lamella thickness is impractical to achieve, the method can be adopted to inform the extent to which exposed timber is justifiable.

Figure 3: The climate innovation district in Leeds is benefiting from OFR’s CLT research collaborations with BRANZ. Photo: CITU


Adopting the method generally shows that a by-product of the enclosure being constructed of a combustible material is an increase in fire severity. Where it is necessary to have some of the enclosure’s exposed timber encapsulated, any protective linings should be specified to achieve a fire resistance that is capable of withstanding the burnout of the relevant design fire conditions and in consideration of the impact any exposed combustible enclosure material has on fire severity. Armed with charring depths, the extent of protective linings and any constraints on exposed lamella thickness, designers are then in a position to undertake relevant checks on the loadbearing performance of the structural timber elements. n

Fire performance of contemporary timber buildings Wojtek Serwatka and Matt Smith examine the key issues.


n August 2006, two natural historians Chris Atkins and Michael Taylor discovered Hyperion – a giant coast redwood, towering a record-breaking 116m above the Redwood National and State Parks in California. The record was short-lived; in April 2007, it was surpassed by a 153m-tall man-made ‘tree’ – Tianning Pagoda in Changzhou. As of 2018, the temple still holds the title for the tallest timber structure ever created, but it is likely to lose its crown in the upcoming decades.

Architects and developers are becoming increasingly interested in using timber as a main structural material. The primary drivers are: • sustainability • innovation • speed of erection • market demand. Recent developments have proved the solution can also be economical and efficient. Notwithstanding the development in structural timber, the question often asked by the public is: how can tall timber structures be made safe for fire? That is where fire engineers play a role.

Two approaches Even trees can’t grow indefinitely. The maximum height a tree can reach is about 130m.1 Similarly, the height of mass timber buildings is also limited; not only by physics, but also by building regulations. In fire safety design, there are two approaches: prescriptive and performance. The prescriptive path focuses on satisfying the prescriptive (code-based) requirements. There is no requirement to understand the principles of fire dynamics, smoke control or human behaviour – if the clauses of the building regulation are satisfied, the design is deemed to be safe. The ‘magic numbers’ and ‘golden rules’2 embodied in the building regulations are accepted without question, but even a small diversion from the code will require the design team to develop a disproportionately detailed proof that an adequate safety level is achieved. For example, if the distance from the nearest exit door is 10% longer than the maximum allowed by the regulations, it should not be difficult to prove that an improvement in fire safety measures will compensate for the increased travel distance. However, in most cases, the designer will be asked to perform a comprehensive fire safety analysis. The prescriptive approach is limited, and if the project is of unusual shape or incorporates untraditional building materials, it is very difficult to prove code-compliance. That is where the performance-based approach emerges; proving that the structure is safe with a holistic fire engineering analysis.

In North America, the building codes state that tall structures shall be of non-combustible materials (which timber is not), and the exact storey limit depends on the building properties and local codes. Tall timber structures beyond the code limitations require an ‘alternative solution’ – a justification that the structure performs equally well to the ‘acceptable solution’. >> Timber 2019 Industry Yearbook

| 101

Timber structures Fire safety

This alternative solution path creates the opportunity for elements of the performance-based approach to be applied. In the UK, the design needs to meet the performance requirements, for example a certain fire resistance. The path taken to satisfy the ‘functional objectives’ is of lesser importance. However, in the aftermath of Grenfell Tower fire and at the time of writing, the Building Regulations have recently changed and introduced a ban that prohibits the use of materials other than those classified A1 or A2-s0,d0 to BS EN 135011:2007+A1:2009 in the external walls of buildings with a storey above 18m.3 Cross-laminated timber (CLT) does not meet this requirement and it is currently uncertain if CLT will be eventually be exempt from the ban, although there is a great amount of discussion within the industry on this matter.

The reason for this behaviour is charring, a process characteristic of thermosetting polymers and most solid organic compounds. It is a process of an incomplete combustion, leaving a porous residue composed primarily of carbon. In heavy timber members subject to fire, a char layer insulates the virgin material underneath. The protection of timber can be further increased with an application of fire-retardant coatings or impregnated treatments for smaller timber elements. Currently available semi-transparent products allow for an increased fire resistance, while retaining the natural beauty of CLT.

Nevertheless, high-rise timber buildings must also feature conventional fire protection systems. This includes, but is not limited to: • sprinklers • detection and alarm systems • compartmentation • smoke extraction. In the design of mass timber buildings, it is good practice to incorporate passive and active fire protection systems exceeding the regulatory requirements to further demonstrate fire safety.

Demonstrating performance The achieved level of safety can be demonstrated quantitatively with a variety of tools: from simple analytical relationships, through numerical models to full-scale laboratory testing.

Will it burn? Combustibility of Figure 2: T20 – timber high-rise residential tower. Feasibility study for UK and Canada. Source: Entuitive timber depends on many factors, with one being the most important: size. Anyone who has prepared a campfire knows it intuitively – one cannot start a fire with a tree-trunk size log. No matter how long we try to ignite it, the log will not sustain burning once the applied heat is removed. However, if exposured to heat for long enough, eventually even the largest logs will ignite.

Architects and clients often wish to expose large areas of structural timber in bespoke projects. The exposed timber surfaces may continue to burn after the entire fuel load (furniture, stacked paper etc) has been consumed.

Fire behaviour A typical fire can be divided into three phases: • growth • developed fire • decay. Each phase presents a unique challenge to be considered in design.

Figure 4: Three phases of fire development. Source: Entuitive

Timber structures Fire safety

Growth phase is the first stage of a fire and concerns life safety. The fire engineer must consider how the fire growth and smoke development affect the safety of evacuees. It is followed by the developed phase, which concerns the structural safety. The conditions are no longer tenable and are endangering the structural integrity of the building. The last phase, decay, is of special importance in timber buildings; a secondary fire development may occur if the wooden assembly continues to burn.

Growth phase: life safety To ensure evacuation is possible, the Required Safe Egress Time (RSET) must be shorter than the Available Safe Egress Time (ASET). The RSET is the time required for all occupants to evacuate and includes detection, pre-movement and travel time. ASET is the time it takes to reach untenable conditions (toxin concentration, temperature and visibility) in egress paths.

Developed and decay phases: structural capacity While the growth phase of a fire mainly influences life safety and evacuation, the developed and decay phases are those with most impact on the structural capacity of a timber structure.

Figure 5: Visual representation of ASET and RSET. Source: Entuitive

During the growth phase, internally exposed timber can increase the rate of growth of the fire, thus reducing the ASET. It is worth noting that conventional buildings are permitted to have a certain amount of combustible internal finishes, which contribute to the growth phase of the fire in a similar fashion. Fire engineers quantify the time it takes to reach untenable conditions with empirical correlations or computer modelling. Timber construction can lead to a higher uncertainty in ASET. For that reason, mitigation measures to reduce RSET such as improved signage, wider stairs and doors, active fire protection or reduced travel distances are available to fire engineers to design an egress strategy that ensures an adequate performance. www.trada.co.uk

A concern during the decay phase for a timber building is whether the timber actually self-extinguishes after consuming all fuel in a compartment. In severe cases, an exposed timber structure may lead to a secondary flashover. Fire engineers must ensure that the timber structure will self-extinguish after the fire load in the compartment has burnt out. Current research suggests ranges of heat flux and mass-loss rate (rate of fuel consumption) can be used to determine if timber will self-extinguish.4 However, the phenomenon is subject to variables such as: • ventilation • compartment geometry • compartment construction. Currently, the most definitive way to determine if the compartment will extinguish is to perform full-scale tests. In future, it may be possible to use numerical simulations to determine self-extinction without laboratory testing. >> Timber 2019 Industry Yearbook

Timber structures Fire safety

Structural capacity during the developed and decay phases is typically demonstrated by calculating the amount of timber charring that has occurred and the remaining load-carrying capacity of the timber elements. A typically assumed charring rate is 0.65mm/min, although it varies depending on: • material • geometry • fire exposure • fire protection treatment applied. CLT is known to char non-linearly. As the char layer penetrates the material, the lamina may spall off, exposing the virgin material underneath sooner than anticipated.

Nail-laminated timber (NLT) chars linearly due to the vertical alignment of laminae. However, there is an opportunity for the sides of laminae to char if the connection is not robust and the cross-flow upwards is prevented.

Charring of longitudinal members (beams and columns) is slightly different. The heat transfer is no longer one-dimensional and can act on all sides of the member. This results in corner rounding.

Fire engineers must demonstrate that the timber structure has a sufficient loadbearing capacity for the duration of the fire, taking into account the portion of the material lost to charring. In long-span floors, the size of members is likely

to be governed by deflection or vibration, rather than the loadbearing capacity; hence the fire resistance is already provided. In columns and walls, the size is often dictated by the axial stress capacity, thus the ‘protection by oversizing’ in size may be necessary.

Connections Finally, a key consideration in timber buildings is the connections. Conventional connections in the timber assembly use steel as the connector material. Metal parts can conduct heat rapidly into the connections, where the mechanical stresses are the highest.5 Long fire exposure can lead to charring around the connector and separation at the interface of the two materials. Researchers have investigated the use of non-metallic connections in the past, primarily replacing steel with glassfibre-reinforced polymers (GFRPs), with good results.6 Connection performance during a fire can be demonstrated using charring calculations, thermal analysis or laboratory testing. Typically, metal connections are protected with intumescent paint or are fully encapsulated within the timber member.

Engineered timber CLT

“CLT has the structural properties of heavyweight construction materials combined with the lightweight and adaptability benefits of timber. CLT is made from relatively low-quality timber that is manufactured into a solid wood construction product composed of bonded single-layer panels arranged at right angles.�


here are three reasons why now is the right time for cross-laminated timber (CLT) to be used in off-site construction. First, the UK Government has reaffirmed its commitment to off-site modular construction as a key solution to solving the housing crisis. Second, and perhaps less talked about, is the construction skills crisis. With skill shortages looming, combined with an ageing construction workforce, the industry must capitalise on the opportunity to attract new entrants into the sector. Third, the Prime Minister Theresa May has reiterated her pledge to halve new building energy use by 2030 and the construction industry must use this to create a driver for modernisation. To address the significant climate and energy challenges, solutions must filter down into the way we build to make the housing stock fit for the 21st century.

Traditional off-site volumetric assembly Volumetric buildings need to be much stiffer than conventional constructions, and must be able to resist racking and deflection when being lifted into place. Many conventional off-site systems use light gauge steel construction, which is a cold-rolled steel frame without the protection of hot-dip galvanising for durability. These systems require imperforate internal vapour barriers to prevent interstitial condensation inside the frames; this is difficult to achieve, especially within floor voids and around joists. CLT enables the airtightness membrane to be moved to the mid-wall and externally insulated. This creates fully breathable walls akin to Goretex jackets, improving the quality of the internal environment, removing the need for a vapour barrier and letting the building breathe. It also prevents users from being able to pierce the membrane, which gives greater durability and longevity to the initially tested air-tightness levels. Breathable wall systems also prevent issues arising from incorrect user ventilation of the building. >> www.trada.co.uk

Engineered timber CLT

Benefits of using CLT • CLT off-site modular homes are inherently stiff because each wall is a structural plate. • Plates are accurately cut so it is easy to create an airtight structure. • Thermal bridging is minimised by replacing steel with engineered timber. • The structure represents an embodied carbon dioxide sink, rather than having a high carbon footprint.

Structural properties How is CLT different to other timber products? What is new in the way modular construction is using it? CLT has the structural properties of heavyweight construction materials combined with the lightweight and adaptability benefits of timber. CLT is made from relatively lowquality timber that is manufactured into a solid wood construction product composed of bonded single-layer panels arranged at right angles. As such, it is very strong, dimensionally stable and can measure up to 3m x 16m. It is this large panel format that reduces construction processes, saves time in the factory and reduces material interfaces in construction. This simplification and reduction in processes makes CLT a great material to work with for modular house builders. Speed of construction CLT is a fast, dry construction system, which makes it ideally suited to off-site manufacture. Using CLT enables the wall and floor panels of the superstructure to be erected in days under safe and controlled conditions in the factory. The rapid erection enables follow-on trades to commence earlier and the completed unit to still be light enough to transport to sites where it can be erected quickly. This results in an on-site build time measured in days, not weeks and months. Low carbon footprint CLT is an exemplar of the natural cycle, with sunlight converted and carbon dioxide locked up in the trees that are then processed into the final product. Most CLT processes are also closed loop, with waste products used in the production of heat and power. With modern sustainable forestry practices, the security of supply should not be an issue. CLT is therefore a great option for addressing the embodied carbon impacts of building from day one. When considering the properties of CLT that enable the reduced use of high-carbon products such as concrete and steel, the environmental case for CLT is even stronger. www.trada.co.uk

Higher construction standards and environmental performance CLT creates the opportunity to focus on incorporating higher standards of construction and environmental performance into building designs, more so than in traditional construction. By incorporating higher levels of fire-proof insulation, triple glazing, simplified airtight construction, heat recovery ventilation and building integrated photovoltaic roofing and cladding, there is now no excuse for not delivering quick-to-build, low embodied carbon and nearzero operational carbon new buildings. >> Timber 2019 Industry Yearbook

Insulation CLT walls are thinner than traditional brick and block, with space saving an average of 6% to 10%. This means that additional insulation can be incorporated into the same building footprint without compromising on internal space or the number of units planned on site.

Bill Dunster OBE Design Director ZEDpods Ltd

Airtightness Higher levels of airtightness can be achieved through the easy mechanical jointing of CLT panels. As a result, fewer airtight membranes are required, which gives the walls more vapour permeability if combined with the correct insulation and cladding strategy. On-site issues that create difficulties can be eliminated through well-planned, managed and controlled factory processes. Stability CLT is also dimensionally stable with fewer settlement issues than timber frame buildings. Volumetric CLT homes create significantly robust wall and floor structures to enable completely premanufactured pods to be transported to site for fast, factory-quality construction. Is off-site modular housing the solution? CLT certainly has the potential to solve modern-day construction problems, but it relies on clients to raise their expectations and demand a higher-performance product. Above all, the construction industry must have a meaningful debate about quality and durability before engaging in largerscale production. n www.trada.co.uk

“One of the leading UK CLT suppliers, KLH, describes itself as having a ‘zero waste manufacturing process’, with all off-cuts, shavings and sawdust manufactured into biomass pellets.”


here is currently a groundswell of support for reducing waste in our daily lives. The BBC series Blue Planet II is widely credited as being the impetus for many to reconsider single-use plastics; the Environment Secretary describes being ‘haunted’ by the images of plastic pollution1 and is one of many voices now calling for disposable coffee cups to become a thing of the past. The needless use of resources and wilful creation of landfill should be called out and the media support for these campaigns is welcome, but it is worrying how little attention is drawn to the UK’s biggest waste stream – the construction industry. The most recent statistics published by the Department for Environment, Food and Rural Affairs identify construction, demolition and excavation waste as accounting for 59% of all UK waste in 2014.2 By mass, the sector has seen increases of more than 14% in waste generation on 2012 figures, compared with a 7.8% fall in the commercial and industrial sector.3 These are simplistic figures that don’t account for growth in construction output over the same period, but what is indisputable is the scale of the waste produced – 100 million tonnes of construction waste per year, of which 25% goes to landfill.4 It makes the annual 30,000 tonnes of disposable coffee cups5 a figurative (as well as, sadly, literal) drop in the ocean.

Responsible construction and benefits of CLT Not as headline-grabbing as a latte levy, the British Standards Institute is supporting a shift in attitudes through the BS 8895 series – Designing for material efficiency in building projects. It acts as a valuable prompt to designers with a checklist of considerations to optimise material use from the point of resource extraction to the end of building life. Through this lens, solid timber structures offer solutions in abundance and are leading the way for responsible construction. The introduction of cross-laminated timber (CLT) in the early 1990s has opened up new markets for solid timber and it is perhaps not surprising that such a young branch of the industry should be so environmentally savvy. One of the leading UK CLT suppliers, KLH, describes itself as having a ‘zero waste manufacturing process’, with all off-cuts, shavings and sawdust manufactured into biomass pellets.

levels of energy required for its manufacture (just 1% of that required for steel6) and inherent carbon sequestration, CLT offers a near perfect model of efficiency. To create such efficiency in factory conditions is arguably an easier task than managing the same efficiency on a UK building site, but CLT can have a positive knock-on effect beyond a building’s superstructure leading to waste reduction across a whole project.

Saving costs and resources A combined study by Waugh Thistleton Architects, Alinea Consulting and Engenuiti in 2017 ran comparative models for a seven-storey 294-unit residential building in both CLT and concrete. The results identified a significant reduction in pile quantities due to the reduced building weight afforded by CLT with a cost (and resource) saving of 12% over the substructure elements.7 An important differential between CLT and framed structural systems is that CLT provides more than just structure. Used carefully and detailed appropriately, it can also provide a highquality and robust interior finish. For architects this appeals greatly, as it provides an opportunity to add richness and character to interiors without the need for additional finishes.

Reducing plasterboard use Typically in UK projects, gypsum-based plasterboards remain the go-to interior finish for buildings, which is reflected in the levels of waste; it is estimated that plasterboard waste will account for 500,000 tonnes of construction waste by 2020.8 The Construction Resources and Waste roadmap identified 90% of plaster-based products going to landfill and this has now become a target area for improvement.8

Strengthening the argument for reducing plasterboard use (and therefore waste), industry-funded studies suggest that timber finishes offer a benefit to the health and well-being of building occupants.9

Case study Maccreanor Lavington recently tested some assumptions regarding CLT with real-life data after it was appointed to design two of six schools for London’s Borough of Southwark to be built by Morgan Sindall. Both Maccreanor Lavington’s design schemes were constructed from CLT, where the remaining four were a combination of concrete and steel frames. An end of project review by Morgan Sindall’s commercial department ran a comparison of the larger CLT and steel/concrete framed schemes to assess their on‐site efficiency. The study identified an impressive two‐third reduction in the use of plasterboard in the CLT scheme and a 25% reduction in site waste.10

Further research and benefits There is of course an argument that CLT buildings use more timber resources than a timber-framed alternative and are therefore inefficient. Research by Smith and Wallwork engineers suggests CLT buildings use approximately 0.30m3 of timber for every sqm of floor area versus 0.15m3 per sqm for a timberframed building.11 But as seen with the plasterboard example, there are other performance characteristics of CLT buildings that help to reduce the use of other building materials in a project – shifting the balance back in favour of solid timber. CLT structures can: • reduce requirements for external insulation (or enhance overall thermal performance if the same level of insulation is used) • eliminate the need for thermal breaks • offer high levels of air-tightness.

These factors all play a part in reducing overall levels of construction waste. >> Timber 2019 Industry Yearbook

The framed vs solid argument must also sit in the context of timber’s environmental profile; this is an abundant, renewable natural resource, growing in Europe at a rate greater than it can be harvested12 and it is a material that sequesters carbon. Though we should be using all materials prudently, it is tempting to think we should, in fact, use as much timber as possible.

There remains the hurdle of importing the product, which brings with it a loss of efficiency as fossil fuels are burned away transporting the panels across Europe, not to mention financial exposure to fluctuations in exchange rates. All this could change, however, as research at the Centre for Wood Science and Technology at Edinburgh Napier University offers a tantalising glimpse of potential for UK CLT production13, which could further propel solid timber up to the environmental top spot.

Tom was the project architect for two RIBA Award-winning CLT schools (Grange Primary and Charles Dickens Primary schools in London). He is a timber-construction champion and has spoken on the role of CLT in education at Ecobuild (now Futurebuild). He is currently leading the design of a new timber-framed refectory building for Ibstock Place School in Roehampton.

“The benefits of timber in the commercial refurbishment sector, such as lightweight construction, speed on site, wellness credentials for workers and users, and aesthetic appearance, is ten-fold.�


n the UK, most timber-framed buildings are in the residential, educational or public sectors. However, timber can offer an array of solutions for commercial clients.

Timber is a great choice for office refurbishment. Compared to steel and concrete, its lightweight properties are perfect for the addition of storeys to existing buildings, reducing the potential strengthening required to the existing structure and its foundations.

Office refurbishment At 10 Lower James Street, a dramatic double-height mansard extension is constructed solely in cross-laminated timber (CLT). With the demolition of the previous plant room, the use of CLT actually reduced the load on the existing listed 1930s building. An innovative concealed moment connection creates a seamless timber internal space.

Roof extensions such as these are common in London, but more often than not steel and lightweight metal deck solutions are preferred construction methods. Developers and insurers are sceptical of using timber frame, quoting often unfounded concerns such as design life, fire and cost. Much literature exists to dispel these concerns and there are many case studies to support the use of timber in commercial projects. As design detailing evolves for this still relatively new approach, even greater confidence will be provided that design life can match that of conventional construction methods. >> www.trada.co.uk

Engineered timber CLT/Glulam

At East India Dock, as part of the Republic masterplan, 650,000 sq ft of high-quality, low-cost workspace will be created, along with a wide range of amenities and extensive public space. The masterplan will be realised in three phases. The Import Building was completed in 2018, formerly referred to as Anchorage House.

Phase 2 includes the Public Realm elements of the project and is also now complete. The works include partially infilling and re-routing the existing waterway and providing a series of tall CLT pavilions that appear to float above the space. Phase 3 is the Export Building, formerly Capstan House, and it is currently on site. For this phase a two-storey extension to the building is being installed with a glulam and timber frame, designed for a future additional three storeys. The use of such a lightweight construction technique has meant that the existing basement construction and its foundations beneath have been justified for the additional five floors of extension, only four of which were possible in steel and metal deck slab.

At Anchorage House, the architect developed an exciting scheme to infill in part the existing atriums with glued laminated timber (glulam) and CLT, creating a dramatic and tactile space while gaining additional floor space and interaction between the floors. It was possible to justify the additional load on the existing reinforced concrete frame due to the availability of extensive archive information, backed up by intrusive investigation, as well as the lightweight nature of the material.

Benefits The benefits of timber in the commercial refurbishment sector, such as lightweight construction, speed on site, wellness credentials for workers and users, and aesthetic appearance, is ten-fold. Existing reinforced concrete frames, from 20 to 30 years ago, tend to have excessive capacity, and there is a growing trend to update office space to allow flexible and co-working spaces. >> Timber 2019 Industry Yearbook

Engineered timber CLT/Glulam

New build commercial There has been extensive research and development into creating the most efficient solution for new build office construction in Borough High Street. Photo: Heyne Tillett Steel steel and metal deck. Lightweight steel beams span long distances with large web openings creating flexible open plan spaces and a zone for services to route through. The beam weights are further reduced by using the metal deck slab as the top flange of the beam via shear studs. The optimum structural and services zone is then provided, reducing building height in restricted planning areas, reducing cladding costs and even potentially squeezing in an extra floor for some instances. It is hard for a timber solution to compete with such a wellrounded, industry standard approach to new build office developments. Currently, timber only comes into its own when: • an even more lightweight solution is needed • the structural zones are not a key driver for the project • the client is keen to use it for its aesthetic and wellness characteristics • the installation programme is key.

Research Heyne Tillett Steel (HTS) has been researching current timber designs. Currently, glulam beams are designed to stand alone with CLT sitting on top, taking no benefit of the CLT top flange. Composite glued-in factory timber panels, brought to site as cassettes, have several disadvantages: • holding up factory time to create the cassettes • potentially creating air spaces in transportation • adding cost to the solution, which may outweigh the depth reduction gain. Searching for a more standard and buildable win, HTS looked at composite action from screwed on-site connections. The theory assumes the CLT spans between secondary beams using its full depth and the central layers only contribute to the composite T along the length of the secondary beam. As the top flange of the T is in compression, it is assumed that any friction between panels and the locked joint is adequate to transfer the forces. www.trada.co.uk

Eurocode 5 (EC5) currently has a clause in Appendix B that partially deals with this situation, yet is mainly based on creating I-beams from softwood, rather than Ts from two different engineered materials. The equation appears conservative and does not account for the type, length or incline of the screws used, giving minor gains on a glulam-only design. HTS partnered up with City University of London to test a series of screwed connection arrangements along with two full-size tests with different screw spacings. The initial small-scale shear tests showed that screws at a 60 degree incline gave the highest screw capacities. The larger tests were then undertaken with 7mm-diameter 260mm-long screws at 60 degrees towards the centre of the span and at varying centres. Initial results show a clear improvement on a glulam-only design and the current EC5 method. Both tests gave a tensile/bending failure in the glulam beam, rather than a failure of the screws as expected. It appears that the mobilisation of the effective width of CLT through its layers is more of an issue than the partial composite action from the screws. HTS is currently working towards finding a solution to calculating the effective width of the CLT and therefore the impact of the partial composite action provided by the screws.

What’s next TS hopes that its work and research will encourage others H to get involved in developing solutions to make timber more efficient for commercial buildings. Further research is being made into other relevant aspects, such as: • plated web openings • composite hard and softwood beams • other composite floor systems. Timber as a material is easy to work with, quick to install, requires no finishes and naturally creates a feel-good environment; it seems a no-brainer to use this in the commercial sector, too. n

Engineered timber Adhesives

Eliminating the use of adhesives and steel connections in engineered wood products Dan Bradley reports on an international research project that hopes to develop an alternative.


lued laminated timber (glulam) and cross-laminated timber (CLT) construction techniques offer significant environmental advantages compared to steel and concrete, both in terms of resource sustainability and wider environmental impacts. However, challenges remain in delivering fully sustainable engineered wood products (EWPs), given the petrochemical adhesives and steel connections inherent to glulam construction.

What are the issues?

and contribute to the cumulative exposure of people living and working in glulam structures, especially in cases where glulam is used as an exposed architectural feature. The embodied energy and associated CO2 emissions of glulam compare very favourably to steel and concrete. The use of adhesives and steel connectors, however, accounts for a large percentage of the energy used in manufacture and consumes finite resources. Eliminating these therefore has the potential to significantly increase the sustainability of EWP production.

Within the EU, some 16 million tonnes of timber waste from construction are sent to landfill each year. This represents 40% of that generated by demolition, refurbishment and building waste. The remaining 60% is reused or recycled, including via incineration for heating and power generation.1 However, reuse of glulam EWPs is not straightforward. The toxicity of the glues generates a chemical hazard when the timber is cut and complicates repurposing as chips or solid fuel. Additionally, the integration of steel connectors results in a mixed demolition product that also hinders ease of recycling.

The project

The inherent toxicity of many of the commonly used adhesives, such as melamine urea formaldehyde and phenol resorcinol formaldehyde, also presents issues during manufacture, use and demolition. Although in concentrations well below legal safety thresholds, volatile organic compounds (VOCs), such as isocyanate and formaldehyde, reduce indoor air quality

Objective one The first is to replace the adhesive in glued EWPs (for example, glulam and CLT) by upgrading 20th-century Brettstapel techniques with highly densified softwoods. Traditionally, Brettstapel uses fully desiccated hardwood dowelling to fix arrays of softwood laminates together to form structural elements. When the moisture content of the dowels equilibrates with the surrounding softwood, it seeks to expand creating a constant pressure at the join, maintaining a tight fit and thus a rigid EWP.

Towards Adhesive Free Timber Buildings (AFTB) is an international research collaboration funded by Interreg NorthWest Europe, an institution of the European Commission, and led by engineers at the University of Liverpool. The aim of the project is to work towards the elimination of adhesives and steel in EWPs by developing an alternative that incorporates both traditional techniques and advanced timber research. There are two main objectives to the work.

By heating softwood timber to c. 130°C, it can be compressed in a hydraulic press to nearly triple its original density without significant damage to its microstructure. This yields a densified wood product with greatly improved properties, for example, a 120 –130% increase in strength and stiffness (based on three-point bending tests). By replacing the desiccated hardwood in Brettstapel with densified softwood dowels, the strength and stiffness >> Timber 2019 Industry Yearbook

of the resultant EWP is increased. Additionally, what has long been perceived as a drawback of densified wood is an advantage here. Once in contact with moisture, an Existing adhesive free timber connection. irreversible springPhoto: Professor Masahiro Inayama, Tokyo University back effect occurs as the densified wood seeks to relax from its compressed form. This provides a permanent tight fit in the EWP regardless of future humidity changes in the operational environment. Additional benefits of this approach are the lower cost and faster regrowth of softwood timber, compared with hardwood.

Objective two The second objective is to provide an alternative to steel, for semi-ductile connections, by combining the dowels with compressed wood plates that bridge connecting timber sections, for example in beam-to-column connections. Such connections exhibit ductile properties resulting from the embedment of the compressed wood dowels in the softwood sections. The research on these connections is being led by National University of Ireland, Galway.

What’s involved The three-year project will take the EWPs and construction techniques through comprehensive, multi-scale structural testing, combined with a programme addressing vibrational serviceability and fire performance, led by Université de Lorraine. Along with its contribution to the wider testing programme, Technische Universität Dresden is seeking to deliver greater innovation by combining adhesive-free techniques with advanced robotics to produce free-form space structures. The technique involves using CAD and numerical models to specify a set of cutting instructions for a robotic saw that can control precisely the angle at which timber is sawn, and can modify this angle as it moves. The resultant planks or laminates are contoured exactly, so that they may be steam-formed into a ribbon of any designed 3D shape. For the AFTB project, these laminates will then be connected via densified wood before being tested or used. Assembling such EWPs allows an architect or designer huge freedom in the design of space structures and aesthetic elements, while offering a fully sustainable product. The collective testing output from the project will be combined with numerical simulation methods developed by the Luxembourg Institute of Science and Technology, which www.trada.co.uk

is also producing a user-friendly structural design tool to allow engineers to specify and optimise adhesive-free EWP designs to fit end-use requirements.

Outcomes In late 2019 the project will deliver three ‘demonstrators’: exemplar buildings near Liverpool, UK and Epinal, France. These will act as test beds to prove the long-term robustness of adhesive-free beams, columns, arches, connections and CLT panels; while in Dresden, Germany, a grid-space structure will be assembled. This artistdesigned installation will demonstrate the feasibility of adhesive-free timber space structures while also promoting timber construction and civil engineering to students and the wider community.

A key requirement of the project funding is that AFTB engages with businesses, regulators and the general public in the north-west Europe area. We are very interested to hear from anyone with an interest in using the technology, or anyone with a comment or question about adhesive-free EWPs. n

Joinery Stairs

“The staircase was made from an engineered timber sheet material, CNC-cut directly from the architectural drawings as a means to budget efficiency while retaining control of design.�


he prefabricated timber staircase at Askham Road formed part of a one-off new-build contemporary house, situated on a modest end-of-garden plot in west London. With issues of privacy and overlooking influencing available fenestration, it was important to design sensitively and introduce light through clerestory glazing, roof lights, a stepped terrace down to the basement and the open stair core at ground-floor level. With such varied fenestration came the decision to treat the interior spaces of the house with a plain, pared-back look and finish, letting the different angles of light provide the interest. With this simple approach to interior space, the staircase became an opportunity to create a striking architectural feature within a plain space, materially distinct from its surroundings and able to permeate light through to different levels and angles.

Aspirations and procurement opportunities The staircase was made from an engineered timber sheet material, CNC-cut directly from the architectural drawings as a means to budget efficiency while retaining control of design. As a result, an entire layer of surveying, drawing and administration was omitted from the construction process. This subtle change in procurement added a new dimension to the design and detailing process, including consideration of the sequencing of installation and physical access, which required the fitting of certain stair elements once others had been installed. Naturally, a great deal of care in establishing survey data and design tolerances was required, all of which would become the responsibility of the architect; a challenge rarely accepted by the profession. The installation is made entirely of 42mm-thick TinTab multiply sheets1, with the exception of screws and handrail brackets. All vertical support is provided by 100mm-wide uprights at 110mm centres, and the same 42mm section is installed as a batten inbetween the open treads, to comply with building regulations. Given the direct procurement approach there was no opportunity to work or finesse the material or joints as might be expected in a joinery workshop, hence a conscious decision >> www.trada.co.uk

was made to express and articulate the raw cutting process with the radii of the CNC machining tool left on show rather than being filled, hidden or squared off. In effect, the limitations of the process were considered at the design stage and expressed in the finished article. The staircase is top-lit via a large window to the street at first floor; this gives a warmth to the light coming off the surface of the wood.

Assembly and completion Assembly of the staircase was somewhat of a puzzle and much effort went into organising all the elements so that none were lost or installed incorrectly (many looked very similar). Each piece has a unique number CNC-etched in an unseen corner, which assisted in correctly identifying where everything went.

Subverting the normal process of procurement, fabrication and installation meant close collaboration between all those involved. The contractor installing the staircase gave essential feedback ahead of fabrication as to how the finishing and completion of the staircase would be tackled. TinTab was chosen in part due to the large format of the sheets available, meaning very few flitch connections were needed, only to the tallest vertical stanchions. However, other physical properties of the chosen TinTab sheet, with softwood block core, required that each tread underwent a simple load test, under the guidance of the structural engineer. The contractor had to work around the installation, as simply taking delivery, sorting and storing the various pieces, some of which only just fitted into the house due to their size and length, required flexibility and care. >> Timber 2019 Industry Yearbook

While the adopted design, procurement and installation route yielded significant savings over a conventional approach to producing the staircase via a specialist joiner, it nonetheless had its challenges: an understanding client was required as, while each and every piece was fitted first time and as intended, an inevitable element of iterative learning happened as part of the successful completion of the project.


The assembly of the staircase was like a jigsaw puzzle. Photo: Anthony Coleman


The delivery of successful architecture relies on an understanding of how buildings are built and used, so there was no better opportunity to learn first-hand the challenges of construction and how they reflect on what happens at the design stage than taking on the responsibility of fabrication ourselves.

There was a conscious decision to reflect certain constraints in the fabrication and assembly process that resulted from not having a specialist or craftsman input in the final design. For this reason, although the finished article was highly pleasing, it could, arguably, be more highly crafted. In this regard, lessons learned can be used to further refine the process for the next design. There are also plans to finesse the line between where our potential fabrication limit ends and others begin, perhaps with larger, more complex installations where we undertake just one element of it rather than the whole. It was an exciting and highly informative design challenge with an outcome that works in function and aesthetic, but one that worked in execution, too. n

Protection Fire doors

Fire door safety and the importance of third-party certification Hannah Mansell on the MHCLG fire door investigation, where the fire door industry is now and whether the standards of fire door safety have improved since the Grenfell tragedy.


n TRADA’s 2017 Industry Yearbook I explored the role of the ‘Responsible Person’, who has the legal responsibility for fire safety in a building. At that time, independent research carried out for Fire Door Safety Week highlighted that almost half of property owners (46.5%) 1 said that they either did not know what their legal obligations were, or admitted they were unclear. Two years on, the unspeakable loss of the Grenfell Tower fire tragedy has pushed building fire safety to the top of the agenda. Unfortunately, the lack of awareness and proactiveness of the Responsible Person is just one of the many issues.

Disasters such as Grenfell happen because multiple things have gone wrong, multiple layers of protections have been breached and multiple mistakes have been made. Focusing on fire doors, the industry must unite and put best practice, certification, traceability and independent scrutiny at the top of its agenda.

Fire door performance If you that have supported the Fire Door Safety Week campaign since its inception seven years ago, you will know that the British Woodworking Federation (BWF) has long called for improvements to fire door safety in social housing2 and the mandatory requirement for third-party certificated fire doors. I was horrified, but sadly not surprised, when in January 2018 the Met Police recovered a composite foam-filled fire door from Grenfell Tower that only achieved 15 minutes fire resistance when furnace tested.3 Fire doors are classified in terms of their ability to resist fire (in minutes) and cold smoke. All fire doors placed on the market in the UK must have test evidence to validate performance claims. But as many who work in the fire door industry know, relying on a snapshot test report that is years out of date can be risky because it’s just a one-off pass; it doesn’t demonstrate repeatability and there’s little or no traceability linking the product supplied to the customer back to the original specification that was tested. Fire doors that are manufactured in isolation without independent scrutiny are unlikely to be subject to a retest programme when the design is changed, or there is a change in the supply chain for raw materials and/or components. Unfortunately this means that there are potentially thousands of fire doors fitted across the UK that will not perform as they claim in the event of an actual fire. For a life-saving product, this is disgraceful and is why independent third-party certification of life safety products is the minimum standard that should be accepted.

Third-party certification of fire doors

Products that are manufactured under independent thirdparty certification must have robust control systems in place to ensure they are made to a consistent specification, have traceability and are supplied with essential product information to allow others in the chain of responsibility to ensure the product remains fit for purpose throughout its service life. >> Timber 2019 Industry Yearbook

On 18 December 2018, the Government announced that it is implementing in full the recommendations of the Hackitt Review through the Building a Safer Future plan. The BWF welcomed this news, with its members manufacturing around three million third-party certificated fire doors in the UK each year. The Building a Safer Future plan is a muchneeded step forward for the fire door industry, providing an effective regulatory framework and more accountability that will be supported by the introduction of clearer standards and guidance. BWF is hopeful that third-party certification will be enforced by legislation at some point over the next 18 months. Following on from the Grenfell tragedy, issues with product performance supplied by certain door manufacturers have been highlighted in the national press. Through responsible third-party certification, the ongoing testing, independent auditing of control systems and product traceability would be a routine task, helping to drive standards within the industry. However, this does pose the question: what should the industry do in the meantime? It should not have taken Grenfell to bring this to the forefront, but now is the time to look forward and make fundamental changes to how the industry operates. The entire fire door industry shouldn’t be waiting for the Government to instruct it instead the industry should be taking the lead. Not only does this affect how fire doors are made, but how they are installed and correctly maintained. For a fire door to perform on site, it should be installed in exact accordance to the complete specification stated within the third-party certification scope detailed on the associated documentation and manufacturer’s instructions. This documentation will detail all limitations of the product (relating to size and configuration), installation instructions and precise specification of all the compatible components that can be used (such as intumescent seals, glazed aperture systems, etc). It’s crucial that this specification is adhered to for correct installation and essential ongoing maintenance.

Promoting an understanding of passive fire protection measures The issues around fire door safety don’t just exist in high-rise, high-risk buildings. They are prevalent in pretty much any sector and building type that you think of: • public and private residential accommodation • educational • specialist housing • defence and secure accommodation. www.trada.co.uk

These places house some of the most vulnerable members of the community. BWF is currently planning for the eighth Fire Door Safety Week. Taking place from the 23–29 September 2019, BWF will continue to raise awareness of the critical role that fire doors play in saving lives and protecting property by using case studies and public feedback to help stamp out future bad practice. Awareness about the critical role of fire doors has certainly grown in the months after Grenfell, but there is still a long way to go and that’s why campaigns such as Fire Door Safety Week are so important. People deserve transparency regarding the performance of their products and have the right to question the performance of existing provision. n

Protection Fire

Enhancing the fire performance of wood as a construction material Gordon Ewbank looks at how flame-retardant treatments enhance the fire performance of wood-based products and what steps specifiers can take to ensure correct specification and verify materials as they arrive on site.


n the critical early stages of a fire, it is the reaction to fire properties of the various materials and substrates exposed that are vital, that is:

• ignitability • heat • smoke • burning particle release • subsequent spread of flame across the surface.

Critical terminology relating to materials and fire Reaction to fire is the measurement of how a material will contribute to the fire development and spread. An EU classification serves as the standard of evaluation for the reaction to fire of construction and building materials, and establishes uniform Europe-wide requirements under EN 13501 Part 1.1 As the fire grows within an enclosure there comes a point when there has been sufficient preheating of all the surfaces that they all ignite within seconds of each other. This is called flashover. At this point the fire becomes developed and containment becomes the top priority, with the use of compartmentation as the common strategy.

Stages of a fire – temperature v time. Source: WPA Flame-retardant treatment will enhance the reaction-to-fire properties of woodbased materials, reducing ignitability and consequent spread of flame. This slows down the development of the fire, allowing significantly more time for the occupants of a building to escape and for the fire to be extinguished.

Flame-retardant treatments

At this stage, it is the fire resistance ratings of building elements such as walls, floors and fire doors that become critical (for example 30-, 60- or 90-minutes’ fire resistance as defined in EN 13501 Part 22).

There are two ways that flame-retardant (FR) properties can be effectively conferred on wood and wood-based materials: 1. The treatment of finished products using either high-pressure impregnation with an FR solution or the application of a suitable FR surface coating, applied under factory-controlled conditions that are independently quality assured. 2. The incorporation of an appropriate flame retardant as an integral part of product manufacture (for example FR MDF, OSB or plywood).

Fire resistance is the measurement of the ability of a building/construction element to resist, and ideally prevent, the passage of fire from one distinct area/building compartment to another.

Note: The brush or spray application of an FR coating on a construction site is not recommended as consistently achieving the loading/thickness of coating required by the coating’s manufacturer cannot be guaranteed or indeed verified. >>

Ensuring the correct specification of flame-retardant treated wood What reaction to fire performance is required? Euroclass B or C in accordance with BS EN 13501. (FRs work by making wood more difficult to ignite and by slowing the rate at which the timber burns, improving its rating from Euroclass D to either Euroclass C or Euroclass B – the highest rating for all organic materials.) Note: Classifications according to the much older BS 476 Part 6 3 or 7 4 (typically class O and class 1) currently appear in Building Regulations as alternatives to Euroclass classifications. However, treated wood and wood-based panels with BS 476 classifications are not now widely available since it is mandatory under current legislation that they conform to the relevant EU product standard, such as EN 13986, which means that a Euroclass performance is required.

What is the service environment? The Wood Protection Association (WPA) categorises FR formulations into three types: INT1 Timber in buildings with heating and protected from damp conditions INT2 Practically all interior and semi-protected external situations EXT Components exposed to the weather. www.trada.co.uk

Each type is distinguished by properties that make them suitable for particular applications. The variation in these properties is largely due to the nature of the chemicals used in the formulations and the complexity and degree of chemical reaction required in formulating them.

Checking compliance with specifications Traceability and communication are the keys to ensuring compliance. This is what the 2018 Independent Review of Building Regulations and Fire Safety led by Dame Judith Hackitt refers to as the ‘golden thread’, extending from project initiation right through to completion. WPA operates a series of interlocking quality schemes to help underpin confidence in the fitness for purpose of FR-treated wood-based products, and to ensure end product performance meets supply chain expectations and regulatory compliance. • The WPA Approval Scheme for FR Products provides independent verification of the efficacy of FR formulations. • The WPA Benchmark FR Quality Scheme provides independent verification that such a flame retardant has been correctly applied. >> Timber 2019 Industry Yearbook

Protection Fire

• The WPA Benchmark FR Quality Scheme also provides independent verification that suppliers of FR-treated wood products accredited under this scheme can trace their products back through their supply chain to verifiable fire test certificates and classification reports. Note: Following this logic through will help ensure that: • the FR system used is effective • the FR system has been applied properly • the specification has not been switched somewhere in the supply chain • the ‘golden thread’ has remained intact. For peace of mind, those responsible for specification compliance should ask for: • Fire test certification and a Euroclass classification report relevant to the service environment (WPA FR type), wood species and thickness in question. • Proof of FR WPA approval status (that is, the approval certificate). • Evidence of treatment, where applicable, and confirmation of specification applied. • Guidance on the safe and effective installation of the FRenhanced wood product.

Always check that the description and scope of the material given in the fire classification report quoted by the manufacturer can be taken to apply to the material to be used in the project. Do not accept approximations or cross references to another species or profile. Only reports from valid Notified Bodies (organisations designated by an EU country as competent to assess the conformity of products) should be relied on to justify specification of a treatment or FR-treated material. n

Prolonged exposure of timber structures The successful use of externally exposed structural timber depends on using the right timber, good design, appropriate maintenance and correct specification of preservative treatments.

Protection Preservation

“Good design includes avoiding overdependence on individual members by using load‐sharing members. It may even mean assembling the structure in such a way that individual members can be more easily replaced.”


raditional timber frame structures (post and beam) are built from large cross-sectional solid timbers. They are typically made using mortice and tenon joints, although some more modern constructions may have concealed steel flitch plate type connections. These structures are often constructed from green (undried) baulks, with European oak the most frequently specified timber. Structural engineered timber products are generally not specified for exposure to wetting, because they are usually made from non‐durable timbers and because manufactured sizes are too big to fit inside wood preservative treatment tanks. Some engineered timbers contain components that cannot be exposed to persistent wetting without the risks of corrosion of metal connections/fixings or timber delamination in service. Glued laminated timber (glulam) components are suitable for long‐term external use, provided they are manufactured from timber with an adequate natural durability, or from less durable species that have been pre‐treated with a wood preservative. Some types of plywoods may be suitable for external use, provided they are treated by means of an appropriate wood preservative schedule before edge‐sealing and coating. For footbridges and access walkways, a wide variety of timber species may be used, ranging from lower‐cost preservative‐ treated softwoods, to higher-value durable or very durable temperate and tropical hardwoods. The majority of such structures will be constructed from solid sections of timber. An option with both pre‐treated, less durable softwoods and more durable hardwoods would be to mechanically laminate them using suitably corrosion‐resistant metal connectors.

Designing for exposed structural timber Timber is at risk from fungal decay when its moisture content exceeds 20% for prolonged periods; early symptoms of decay include loss of strength, softening and discolouration. Measures that limit wetting and promote rapid drying will prolong the life of the timber, including: • Protection. Timber members can be protected by using large roof overhangs, capping pieces, flashings, suitably durable and maintained coatings, and end‐grain sealants. >> www.trada.co.uk

• Drainage. Avoid exposing flat, horizontal surfaces or provide an adequate slope for rainwater to drain away. Drip grooves to the underside of horizontal members or anti‐capillary grooves between surfaces in close proximity will reduce water entry into concealed areas. • Separation. Avoid butted joints or overlaps that may allow water to become trapped or drawn in by capillary action. • Ground contact. All timber should be lifted out of ground contact and above the splash zone. Appropriate masonry details, metal ‘shoe’ connectors and damp‐proof courses/ vapour control layers should be considered. • Ventilation. Timber will not decay where there is good ventilation around each of its faces, edges and ends, and where it remains dry. • Maintenance. Regular inspection, maintenance and, where necessary, remedial measures are key to ensuring the desired service life of structural timbers. Good design includes avoiding overdependence on individual members by using load‐sharing members. It may even mean assembling the structure in such a way that individual members can be more easily replaced. This approach can be used with partly exposed timber members, or with structures required to remain in service past their original service life and where repair is more economical than replacement.

Movement and distortion Timber is a ‘hygroscopic’ material, which means that its moisture content will change in response to the relative humidity and temperature of its surroundings. Freshly sawn wet (green) timber will dry out in normal storage, processing and in‐service environments. As timber loses moisture it will shrink across the grain, and as it gains moisture it will swell across the grain. This movement across the grain needs to be accommodated for in the design. Changes in moisture content may also www.trada.co.uk

Timber species vary in their resistance to fungi (the main threat to external timbers) and insects. There are five durability classes under BS EN 350:2016 Durability of wood and wood-based products. Testing and classification of the durability to biological agents of wood and wood-based materials, from 1 (very durable) to 5 (not durable). These classes refer to the heartwood only – the sapwood of any timber species is considered not durable. The heartwood of timbers of an appropriate durability should be specified if the timber is to be used outdoors without preservative treatment.

Use classes and service classes Use classes are used when specifying materials at risk of biological attack by fungi or insects, and are a key consideration when specifying a desired service life for external structural timbers. They are defined in BS EN 335:2013 Durability of wood and wood‐based products. Use classes: definitions, application to solid wood and wood‐based products. When specifying timber for a desired service life, the species, type of preservative, application method and treatment schedule are all determined by the use class. The use class may also be used to determine the required natural durability to achieve the desired service life without preservative treatment. Given the safety‐critical nature and possible consequences of failure of structural timbers, a case‐by‐case assessment of external structural timbers is needed. Site service conditions, design details and maintenance should each be considered when specifying the desired service life.

Preservative treatment Pressure‐applied preservative treatments should be specified for externally exposed structural members if the natural durability of the heartwood is inadequate for the desired service life. Two high‐pressure treatment types are available: copper organic and creosote. Copper organic treatments are resistant to depletion over time due to leaching – they impart a greenish tint to timber though some companies offer a brown dye. The timber will swell and in some cases there may be a risk of distortion. The use of creosote is restricted to industrial applications such as bridge timbers, utility poles and sleepers – creosote should not be specified where there is a risk of skin contact, or contact with food, plant life or clothing. >> Timber 2019 Industry Yearbook

BS 8417:2011+A1:2014 Preservation of wood. Code of practice and the Wood Protection Association’s Manual provide limited recommendations for wood preservative treatments for external structural timbers, amounting to treatment clauses for 15‐year or 30‐year desired service lives for decking joists. The standard also provides ground contact preservative treatment recommendations (use class 4) for sleepers, utility poles, fence posts and other components in ground contact. Treatments for 60-year desired service lives for some end uses may be available by special arrangement with the supplier. Primary structural timber members and load‐sharing timber members for external use will require project‐specific specification. Manufacturers or treatment companies should be consulted as ‘off‐the‐shelf’ treated timber will not be suitable.

Large cross-sectional solid timber It is not commercially viable to kiln‐dry timbers that are more than 100mm thick, so such timbers are likely to be green (undried) or, if air‐dried, available at a moisture content of at best around 18% to 20%. Large cross‐sectional timber is therefore likely to shrink as it dries, which means it also has a higher risk of distorting and may develop large checks in service. Information on the cross‐sectional shrinkage of timbers can be found in TRADA’s WIS 4‐14 Moisture in timber and Green oak in construction book.

Engineered timber

These profiled glulam posts and glulam beams, although exposed, are positioned under a protective canopy, with a wellmaintained finish. The posts are angled inwards, with good drainage, and are supported in ‘shoes’, out of ground contact


Where structural laminated timbers are to be used partially or fully exposed, careful consideration needs to be given to the timber species, adhesive and preservative treatment. Just like solid timber, structural laminated products will need to be made from a suitably durable timber or be treated with a wood preservative. Most standard structural laminated timber is made from whitewood (spruce) or redwood (pine), which are not durable and are

difficult to treat. Pressure‐applied preservatives should be specified, as brush, spray or flood‐coated treatments will not sufficiently penetrate the timber. Glulam beams may be considered unsuitable for pressure treatment with water‐ based preservatives, as wetting carries a risk of surface checking, unless special care is taken with drying. Most glulam timbers, however, are produced using melamine adhesives, which may not be suitable for pressure impregnation with preservatives. Glulam products made using a phenol‐based adhesive may perform better under treatment, though these are not as readily available. If specifying glulam made from a naturally durable timber, it is important to specify heartwood only.

Plywood Plywood for external structural use should have, as a minimum, a class 3 exterior bond to BS EN 314‐2:1993 Plywood. Bonding quality. Requirements. There are two types with a class 3 bond: BS EN 636:2012+A1:2015 Plywood. Specifications and BS 1088-1:2003 Marine plywood. Requirements. Nearly all off‐the‐shelf BS EN 636 plywood is made of low durability timber and will therefore need wood preservation. Marine plywood has specific requirements for durability and for the quality of the face and core veneers used in construction. If marine plywood is to be specified for external use without treatment then standard grade, using timbers that are at least moderately durable, should be used. All plywood used externally, whether treated or untreated, should be suitably edge‐sealed and coated for long‐term exposure, while maintenance should form part of the design and specification process. Design values for structural plywood should be made available by the manufacturer, and all structural plywood should be CE marked under EN 13986:2004+A1:2015 Wood-based panels for use in construction. Characteristics, evaluation of conformity and marking. n

Landscape and exteriors Decking

Are decking installers letting your specification down? You’ve specified the deck. But who should build it? Janet Sycamore reports.

“As a specifier, you’ll no doubt give plenty of attention to the choice of top board. Yet the durability of the substructure is critical to the longevity of the entire deck design, and far harder to rectify should a problem develop over time.”


imber decking is often an integral part of a build. Creative decking designs can add value to your project, transforming and enhancing the exterior landscape.

However, there’s a risk you must address. If you don’t pay sufficient attention to the installation of your deck design, the entire project can be let down. Your reputation can be harmed, and the costs can rack up. The specification might be perfect, considering every component in detail, but that’s pointless without specifying a professional installer, too.

What problems can occur? The key decking installation faults seen tend to fall into the following categories.

Inappropriately specified or installed fixings This is an issue that features time and again, the most common problem being the use of fixings that are not suitable for outdoor use. It might be tempting to cut corners, but the impact can be far greater than the initial cost saving. Galvanised nails not suitable for exterior use should be avoided at all costs. Although coated nails are available that are sold specifically for use in exterior decking, for certain timber species used, due to their acidic nature, only stainless steel fixings are suitable. You should also avoid using dissimilar metals on the same fixing point to minimise the risk of galvanic corrosion. The first sign of a problem tends to be unsightly black stains as the fixings corrode and mark the timber. This is not easy to fix, particularly if nail fixings have been used, as these are hard to remove and replace without damaging the boards. Another common issue is misplacement of fixings; they should be fitted at quarter points across the width and at least 25mm from board ends through the boards and into a supporting joist beneath. If using nails, there are a wide range of nail profiles available, and whether the nail will incur splitting will vary depending upon the application method and the timber used, and so >> www.trada.co.uk

What does the ideal deck installer look like? It is wise to select a deck installer that can deliver your design at every level. Just like a courier company for an online business – they make it happen. If they let you down, you’re the one left picking up the pieces with your customer. The TDCA highlights four ‘must-haves’ when it comes to choosing a reliable deck installer:

Proven track record This might seem obvious. Take some time to review previous work. Go out and see it. Speak to the customers. Focus on decks that were installed some years ago – you want confidence that problems have not developed over time.

some trial and error on spare offcuts may be necessary. If screw fixings are used, care should be taken to avoid overdriving the screw as this can incur a risk of splitting. Drilling pilot holes is best practice, prior to leaving the screw flush with the board, although there are specially designed fixings that negate the need to pre-drill.

No accommodation for the natural movement of timber It is essential that your installer understands the importance of timber moisture content. This can vary throughout the year and the hot summer in 2018 exposed the issue further. A professional installer will know to discuss moisture content with the board supplier, and will also know how to measure it. The Timber Decking and Cladding Association (TDCA) recommends that the decking moisture content should be less than 20% on installation. Sufficient spacing should be left between the boards to allow for movement throughout the year. If you spot deck boards buckling up against each other, moisture content was not managed by the installer. But the negative impact is on your design – and your customer.

Timber knowledge An experienced deck installer knows their timber. They will have worked with a variety of species and will understand the correct techniques to incorporate into your design as you intend. In fact, you’ll want to liaise with your ‘ideal’ deck installer as you specify the project fully. Insurance-backed warranty Not only reassuring for your customer, the existence of a comprehensive warranty protects you, too. What if the installer ceases to trade after you’ve paid a deposit to them? A warranty scheme will put this right. Relevant accreditation Third-party accreditations are worth their weight in gold. Taking the example of the TDCA’s DeckMark scheme, it provides assurance that the installer has a high-quality approach to their work and the capabilities to install a professional deck design. Installers awarded the DeckMark accreditation have been fully audited on-site by independent experts. And this is repeated on an annual basis. No customer testimonial can provide such powerful assurance from experts in their field. n

Poorly specified materials The most common example to quote is the use of internal roofing joists as external deck joists. While timbers sold for this use may be preservative treated, it is unlikely that the preservative treatment will be either of a suitable type or level for exterior use. It’s a poor material specification that will fail. As a specifier, you’ll no doubt give plenty of attention to the choice of top board. Yet the durability of the substructure is critical to the longevity of the entire deck design, and far harder to rectify should a problem develop over time. www.trada.co.uk

“As a general rule, screw penetration into the supports should be at least twice the thickness of the deck board, but considerably more if the timber is particularly dense and strong.�


ne of the most important considerations of timber decking specification is ensuring that deck boards will remain flat in service. When installing decking, the moisture content, the quality of the timber and the fixings are of primary importance.

Specification The risk of boards cupping or twisting in service will be significantly reduced by specifying straight-grained timber, dried to a moisture content of between 12% and 19%. However, using undried timber is sometimes more costeffective, and even if dried timber is used, some risk of distortion will remain and the deck board fixings will play an important role in further minimising the risk of distortion. Hardwoods generally require screw fixings as, relative to softwoods, their greater strength incurs a risk that distortion forces produced by board movement may be great enough to cause nails to shear or pull out, particularly when they are fixed into softwood supports. It is important to ensure that the screw fixings are robust enough to restrain distortion. BM TRADA has come across several instances where hardwood boards have been fixed with screws, which have snapped or sheared in service as the boards distorted, or have been pulled out of the supports. To minimise the risk of screw fixings shearing it is advised to insert screws into pre-drilled oversized holes.

Tropical hardwoods Specifying fixings for dense tropical hardwoods will need particular care given the high strength of these timbers and the risk that some standard decking screws will not be strong enough to restrain board distortion without pull-out from the substructure, or shear or tensile failure of the screw. As a general rule, screw penetration into the supports should be at least twice the thickness of the deck board, but considerably more if the timber is particularly dense and strong. It is also important to consider the gauge of the screw to ensure that it can resist tensile failure. Furthermore, the fixing manufacturer should be consulted on the suitability of its product for the chosen timber species. >> www.trada.co.uk

When fixing hardwood deck boards to treated softwood supports the risk of pull-out must be considered. It should also be noted that if durable hardwoods are used for the deck boards, these would generally be expected to outlast preservative-treated softwood joists, and so it may be preferable to use hardwood supports.

Resistance against corrosion Austenitic stainless steel is the preferred choice for screw fixings. These fixings are available in 304 grade stainless steel, suitable for most external decks, or 316 grade, often referred to as ‘marine grade’, which is typically specified where the deck is exposed to saltwater or other aggressive contaminants.

limits the width between the fixings and therefore reduces stresses induced by any moisture movement in the board. For boards 75mm wide or less, single fixings can be used, but these will offer less resistance to the board distorting. When fixing at quarter points across the board width, screws should be inserted into pre-drilled oversized holes. Because a dense hardwood will not compress as easily as a softwood, additional clearance should be provided between the screw shank and the board by pre-drilling the holes 2mm oversize to allow for any movement. This clearance should also accommodate possible shrinkage of boards up to 150mm in width, if laid at no greater than 20% moisture content.

While the reflectiveness of new stainless steel fixings may make them highly visible on installation, over time the screws will dull and blend in with the weathered decking surface. Alternatively, screws are available with coated heads in various shades designed to match a range of timber colours. However, it should be remembered that the wood itself may change colour over time and the painted heads may suffer from abrasive wear.


Galvanized and epoxy-coated fixings are available and have a good service life. However, a wide variety of coating types are available but not all may be suitable for external decks. Confirmation should be sought from the specific manufacturer on their suitability for use with a particular timber service condition to ensure that the coatings will not deteriorate in the long term.

Risks A particular risk with plated fixings is that, if used with timbers with a high tannin content, such as European oak, there may be a corrosion of mild steel and consequent staining of the wood in the event of the protective plating becoming damaged. The use of salt to avoid icing, or salt from a marine environment, can also cause corrosion with consequent staining. When using coated fixings there is always a risk that the coating will be damaged around the head of the screw during installation. This risk may be reduced (but not eliminated) by torx-headed screws, or similar, which are less likely to incur ‘slip’ as the screw is driven in.

Installation For screw fixing of timber deck boards there are some basic principles of good practice to be followed. For boards above 75mm width, two fixings should always be used, and these are best placed at quarter points across the board width. This reduces the risk of edge splitting, but also www.trada.co.uk

Considerations The countersunk heads of the screws will hold the board down adequately, despite the clearance around the screw shank, but the screw gauge must be sufficient to ensure that the countersunk head overlaps the pre-drilled hole. If the board surface is grooved the fixings should be inserted within the grooves to prevent the fixings from protruding in the event of in-service shrinkage and becoming a trip hazard. Screw heads should be set flush with the base of the groove so that they do not impede the flow of water. If a larger hole is necessary to take up the additional shrinkage of wide or ‘undried’ boards, it may be necessary to fit washers beneath the screw head that are recessed into the board. These washers should be stainless steel with either a hole larger than the screw shank, or a recess in the board that will allow for sufficient lateral movement of the board without the washers binding on the edges of the recess. In this case, round or panheaded screws may be more appropriate than countersunk. Screws have the advantage that, if there is shrinkage in the board thickness, they can be tightened and boards can be removed if necessary. Countersunk screw heads should be slightly recessed below the wearing surface of plain boards, but not to the extent that the holes can accumulate standing water. Fixing screws should preferably be kept at least 25mm from the ends of boards to avoid the risk of end splitting. If boards are butted end-to-end this may mean that they cannot be fixed to a single joist.

Hidden fixings A possible alternative method of fixing hardwood decks is to screw battens to the underside of the boards (allowing an oversize clearance hole in the batten) to form a panel. The panel can then be reversed, laid on the substructure, and the battens fixed to the substructure by screwing through the gaps between boards. Besides eliminating all surface fixings, it is a useful way to either fix a timber deck to a steel substructure, or to provide panels that can be removed for cleaning purposes. This method will give a ‘panelled’ appearance to the deck as the ends of all the boards will coincide. As an alternative to screws, several hidden decking clips are available for use in grooved boards. Deck clips vary considerably in design; some clips are made from plastic or thin steel and are only designed for softwoods, with clips designed for hardwoods being made from stronger materials of sufficient thickness to resist bending or pull-out forces caused by board movement or distortion. High-density, large-movement tropical timbers may require substantial fixings to restrain distortion and most decking clips are not designed for such timbers. www.trada.co.uk

Generally, decking clips are designed to be used with dried timber, and are not designed to accommodate the larger movement expected of ‘green’ or undried boards. Most clips incorporate in their design a method of preventing the boards from being installed too tightly together, typically in the form of pins or ridges that will bend or compress into the timber as the boards swell, but some clips will require careful spacing of the boards during installation to ensure adequate gaps are provided for expansion of the boards. As the design of clips can vary widely, the method of fixing, its suitability for the timber species chosen, and other detailed information should be obtained from the fixing clip manufacturer. n

“Most modification processes enhance the durability of wood against decay fungi. Some modified woods can provide service lives equal to or longer than preservativetreated wood or some naturally durable timber species.”


imber is an excellent choice for an external cladding application. Providing the selected species meet the preferred natural characteristics that benefit the performance of a cladding system, a diverse selection of timber is available. There has been an increase in the range of material choice for external timber cladding in recent years given the growing trend for use of timber in this application. One particular sector of the timber industry that is soaring in popularity is the development of modified woods, which have several benefits that make them a preferred material for external timber cladding.

Benefits of modified woods One of the main drivers for wood modification has been to improve the decay resistance of low-durability timber species, including those grown in Europe. These species normally require preservative treatment to achieve acceptable service lives for many applications. However, apart from improving durability, wood modification may also result in several other beneficial changes to wood properties, including: • improved dimensional stability, and therefore minimal distortion risks • improved aesthetics • increased hardness. These changes have improved both the performance of particular timber species and their range of applications. In particular, the durability and the improved dimensional stability mean that modified woods are well suited to an external cladding application.

Durability Wood durability is the ability of wood to resist attack by wood-destroying organisms. More durable timber species will provide a longer service life. It is an important property to consider when using wood for applications where it is at risk from decay and, since decay fungi are considered the greatest pests of timber in service in the UK, testing the resistance of modified woods against these has received most attention. >> www.trada.co.uk

At present, no European test standards are available to examine the durability of modified wood; tests designed for solid wood are employed, including laboratory and field tests. Some modified species have also been tested for resistance to wood-boring insects and marine borers. Most modification processes enhance the durability of wood against decay fungi. Modification offers an alternative to preservative treatment for some applications. Some modified woods can provide service lives equal to or longer than preservativetreated wood or some naturally durable timber species.

Dimensional stability Improved stability has been demonstrated using all types of modification processes (see Figure 1). Since the cell structure of modified wood products absorbs less water, the equilibrium moisture content of these products is also reduced. Improved dimensional stability reduces movement in service and the risk of cupping and other associated distortion often found in cladding boards. Splitting or checking around fixings over time is also reduced.

Independent tests to evaluate movement characteristics of timbers have shown some modified woods outperform even timbers considered to be very stable, such as western red cedar and teak.

Reaction to fire properties As for unmodified wood, the only practical way to improve performance of thermally and chemically modified wood exposed to fire is to apply a fire-retardant treatment. Effectiveness of fire-retardant treatments applied using conventional techniques has been evaluated. For further information, contact the manufacturers of the modified wood products. Impregnation modification technologies can improve the reaction-to-fire properties significantly. The application of flame retardants is often required for applications, such as cladding, depending on its proximity to a boundary or another building. Further information on the need for fire protection can be found in the Building Regulations.

Modification processes The modification type tends to consist of either a thermal, chemical or impregnation process. Examples of some of these products, suitable for exterior cladding, are presented in Table 1 below.

The enhanced stability of the modified products also improves the quality of finish, particularly if coated. For example, when a high build film-forming surface coating is applied, it will be less likely to be subjected to higher amounts of shrinkage and swelling frequently occurring with natural timber species. Therefore, the elasticity of the coating is less likely to be compromised, which will help improve its service life, and subsequently, increase maintenance intervals. www.trada.co.uk

Appearance Several modification processes change the appearance of wood. Colour post-modification depends on the modification process and the wood species. Thermal modification processes darken lighter coloured woods throughout their entire section. The extent of darkening depends on the timber species, temperature and modification times. This darkening may negate the requirement for staining. Some impregnation technologies include dyes that permanently alter wood colour throughout the section. Where thermally and chemically modified wood products are used for external cladding, the surface will weather to a silver-grey colour, as for unmodified wood. Not all modified woods can be left uncoated externally due to the risk of surface discolouration caused by mould colonisation.

Environmental considerations Another benefit of using modified wood products is the fact that the ‘raw wood’ is sustainably sourced. Most wood species used are obtained from managed plantations in temperate countries (for example, radiata pine, European oak and beech). The chemicals for chemical and impregnation modification processes are often derived from natural materials, often agricultural wastes. These products are designed to remain fixed within the wood on modification and are not released into the environment; they are not biocides and have low ecotoxicity. There are energy costs associated with the production of modified wood products. In some cases, life cycle analyses have compared modified wood products against competing materials, including tropical hardwoods, treated wood products, steel and aluminium. Modified wood products were shown to www.trada.co.uk

perform well against these. Furthermore, unlike preservativetreated wood, there are no special disposal considerations for modified wood products, which may be recycled or used for biomass with energy recovery at the end of their life.

Conclusion The design and installation recommendations of modified timber cladding do not change from that of natural timber cladding installations. Stainless steel fixings are always advised together with provision for adequate drainage and ventilation. However, because of the improved characteristics as a result of the modification process, the overall appearance of the cladding is likely to be uniform, with maintenance inspection intervals and cladding service life extended. These products are a welcome innovation to the modern-day timber cladding sector that compete well with the commonly chosen natural timber species. n

Modified wood floor coverings:

golden opportunity or Pandora’s box?

Peter Kaczmar explains the different modifications available and highlights the importance of correct specification.


ue to recent developments in timber technology and processing innovations, there has been an increase in the use of modified wood substrates as an alternative to natural solid wood floor coverings. Alternative substrates have penetrated the flooring market only relatively slowly as manufacturers have worked to overcome the natural scepticism shown by long-standing users of solid wood in the face of innovative pressures. Now, however, these alternative substrates have taken root to the point where they are increasingly being used for even large flooring installations. Products such as Accoya®, ThermoWood® and Brimstone® are making noticeable inroads into the floor coverings sector. But what are they and what are their benefits over unmodified wood?

What is modified wood? Modified wood is wood that has been treated with a chemical agent, or subjected to a physical process, sometimes involving impregnation, to enhance its performance characteristics. It does not include wood treated with wood preservatives. There are three main types of wood modification process available: • chemical modification • impregnation treatment • thermal modification.

Chemical modification and impregnation treatments Chemical modification involves the impregnation of a permeable species of wood with chemical agents. These react with water-binding sites present in the wood cell wall with the result that the wood becomes much more dimensionally stable and resistant to distortion. Of the modified woods that can be used in the flooring sector, Accoya® is the main example where the chemical modification process (known as acetylation) produces a www.trada.co.uk

hard, resilient and stable material with virtually no cupping, and minimal swelling or shrinkage movement. Accoya® is therefore an ideal candidate for use as interior decorative flooring that can be used in a wide range of interior climatic conditions without fear of the floor buckling or developing shrinkage gaps. Impregnation treatments, such as Lignia®, can also be used for flooring installations. In these cases the wood is impregnated with chemical compounds fine enough to fully penetrate the wood when applied under pressure. These compounds polymerise (that is, bind together in the form of a threedimensional matrix) and fill voids normally filled with air in dry wood. The process increases wood density and hardness. In both processes, dyes may be added that change the colour of the wood throughout its section. This can be used to enhance the aesthetics of softwoods and permits repeated sanding without loss of colour. Again, species that are normally permeable are selected to enable modification to occur throughout the section.

Thermal modification ThermalIy modified woods, such as Thermowood®, Lunawood® or Brimstone®, are produced by thermal modification processes where wood is heated to temperatures of 160ºC to 230ºC for several hours to several days. Heating wood to these temperatures and holding the temperature for these periods alters the chemistries of several natural structural and non-structural polymers that make up the wood, which has a significant impact on the wood, changing its properties. These changes include an increase in dimensional stability, although in many thermal modification processes there is a reduction in the amounts of some structural polymers resulting in a reduction in density, strength and surface hardness. Some of these modification processes may change or enhance the appearance of wood, depending on the process. Thermal modification processes darken lighter coloured woods and >> Timber 2019 Industry Yearbook

different shades can be achieved with different thermal regimes. The colour extends throughout the wood section, which is desirable for flooring where maintenance including sanding is anticipated.

subjected to high footfall, while a third case consisted of a multi-layered floor construction with a 4mm thermally treated oak wear layer used in a domestic environment with low levels of footfall.


In the highly trafficked cases the floor suffered from abnormal levels of fibre loss from the surface, sometimes referred to as ‘fibre-chalking’, to the extent that the floor became heavily pitted after only a few months of service. In the case of the domestic environment, fibre loss resulted in upstanding splinters at the surface that consequently became a hazard to anyone walking over the floor in bare feet.

As with most products it is important to exercise caution when specifying modified wood substrates for specific situations, given that some may have attendant disadvantages that may be overlooked. It is necessary to carefully consider the use of thermally treated woods for flooring, bearing in mind that, for many thermally treated products, there is a tendency for the surface of these products to become softer. Some species may be prone to a reduction in splitting resistance, which may influence the type of installation that is proposed. The use of modified woods as floor coverings has much to offer the wood flooring industry in terms of improvements in dimensional stability and resistance to distortion. These improvements may allow for greater flexibility in terms of the dimensions of board or plank widths used in specific circumstances. Improved hardness achieved with some forms of modification may also extend the range of circumstances in which species otherwise considered as unsuited for use in heavily trafficked environments may be used.

Case studies In two recent cases, solid wood strip flooring made from thermally treated ash and oak was used in public places

At first glance there was not much commonality between the three locations until more detailed microscopic examination revealed that fibre loss occurred wherever the anular rings of the wood were disposed to the surface at a relatively shallow angle. In all three cases the anatomical structure of the species was ‘ring-porous’, which is to say that the individual growth rings were separated by a zone of much larger diameter vessels or pores. The consequence of the arrangement of the pores was such that, where the rings broke the surface of the boards, lines of weakness were created resulting in the fracture and removal of tapered fragments of wood after repeated footfall. In circumstances where non-thermally modified wood is used as flooring, this type of fibre loss is seldom, if ever, encountered. It is the process of thermal modification that brings with it a loss in strength of the fabric of the timber, which can lead to the type of surface erosion described.

Table 1: Current uses for various modified woods

Conclusion It would be short-sighted to curtail the use of thermally modified woods given their characteristics of increased durability and stability. For suitable uses, see Table 1. However, not all innovations are necessarily suited to all types of applications and over-zealous promotion of technological innovations without adequate research-based knowledge may result in damage to consumer confidence. These product innovations present a golden opportunity in the wood floor covering sector to extend the use, versatility and improvement of the overall perception of wood as a floor covering. New ideas are vital for the survival of commercial concerns since they enable industry to better adapt to changes in the marketplace. However, as with all new developments, the industry should be aware that such innovations, without adequate research, may equally become a Pandora’s box fraught with problems borne of rapid change. n www.trada.co.uk

Specifying lesser-used UK/ European timber species, and modified woods Charlie Law assesses the UK’s hardwood consumption and availability, and looks at other available options.


he Grown in Britain (GiB) WoodStock project final report1 illustrates how the UK could make better use of its timber resource. One of the findings highlighted was the UK’s infatuation with one hardwood species, oak.

Hardwood consumption At the time of the report, total UK sawn hardwood consumption was stated as 526,000m3 by the Forestry Commission2, with the UK production element of this estimated at only 47,000m3. From surveys conducted with UK processors, the GiB WoodStock report estimated that oak made up almost 90% of UK production at 42,000m3. For imports of sawn hardwood, the story is much the same. The 2014 Forestry Commission figures3 stated that a total of 496,000m3 of sawn hardwood was imported in 2014, of which 253,000m3 was imported from EU countries, with 168,000m3 of this being oak. Using this data, and including imports from outside the EU (there is no breakdown of species for imports from outside the EU), the GiB WoodStock report estimates that a total of 268,000m3 of oak is likely to have been imported into the UK, which is 54% of all hardwood imports. Looking at the latest import and production data for 2017, the situation does not appear to have changed. Therefore, allowing for a small proportion that is likely to have been exported, oak consumption in the UK is likely to be sitting at around 300,000m3 per annum, which is more than 50% of all hardwood consumption.

Hardwood availability The Forestry Commission has also issued a report on the 50year forecast of hardwood timber availability in the UK.4 The report stated that there was a significant amount of standing timber available for felling, and although many in the UK timber industry believe the quantities quoted are too high, most agree that there is scope to at least double the amount of hardwood timber sourced from UK woodlands. One species likely to increase in availability over the next few years is ash; this is www.trada.co.uk

because of the effects of Chalara (ash dieback). However, further action is required to ensure these quantities are made available, as evidence from sawmills suggests that only a fraction of this timber is making its way to market. This is because there is little or no management of the majority of UK woodland where hardwood species sit, and this must change if the UK is to ensure a continued supply of home-grown timber. The GiB WoodStock study looked at the availability figures and concluded that: • Based on conservative estimates, only 10% of the timber extracted is likely to be suitable for saw quality logs, with the remainder going into the biomass market. • The key species likely to be available are: – ash – beech – oak – poplar – sweet chestnut – sycamore. Based on this data, there is little scope to increase production of oak in the UK, and with one of our key alternative sources of oak being France, Europe’s largest oak producer, already reporting that it is struggling to keep up with demand from countries such as China, continuing to focus on this species is not a sustainable situation. The UK must, therefore, start to promote the use of the other sustainably sourced species to ensure it has a balanced timber market in the future.

Lesser-used species and modified woods Looking at the key species highlighted in the GiB WoodStock study, and assuming other European countries have a similar mix of species, there is significant scope to use lesser-used hardwood, and softwood, species. TRADA’s Wood Species Database contains more than 150 commercial species of timber, with details of their properties and uses.5 In addition, TRADA’s Wood Information >> Timber 2019 Industry Yearbook

Based on this information, GiB carried out a research and development project that demonstrated how thermal modification would work on a range of British hardwood timbers. TRADA member Vastern Timber, based in Royal Wootton Bassett, has taken this research and developed a range of thermally modified ash, sycamore and poplar, which it calls Brimstone.8 This modified timber can be used for cladding, decking and external joinery.

These timbers all have their own unique look and individual properties that can vary between the timber species, so it is always worth consulting with your timber supplier or the TRADA technical team9 if you would like to use a species that you have not previously specified for a project to ensure you can use the species for the intended purpose. One example of where specification changes were made was in the recent fit-out of a Wagamama restaurant. Previously, the specification had called for character French oak for the tables and benches, but due to its rising cost this was changed to GiB ash, which was around half the price. Although the timber species in Table 1 should have good availability, based on the Forestry Commission data, not all will be available in sufficient quantities from UK woodlands certified against the UK Woodland Assurance Standard (UKWAS), which is required for Forest Stewardship Council® (FSC) and Programme for the Endorsement of Forest Certification (PEFC) chain of custody certification. However, an increasing amount of UK Woodland is being licensed under the Grown in Britain (GiB) standard (requiring the woodland to be managed in accordance with the UK Forestry Standard), which allows this timber to be moved under the GiB chain of custody standard. FSC®, PEFC and GiB will all help demonstrate compliance with the EU Timber Regulation requirements, and all are accepted as demonstrating legal and sustainable sourcing under the UK Government’s Timber Procurement Policy. When used for structural applications, the timber will need to meet the requirements of BS EN 1912 Structural Timber. Strength classes. Assignment of visual grades and species. Larch, Douglas fir, sweet chestnut and European oak all meet various strength classes under this standard, so depending on your structural loadings, any of these could be used. >> Timber 2019 Industry Yearbook

As with oak, sweet chestnut and western red cedar both contain tannins that are acidic, so care needs to be taken to avoid iron staining and corrosion of fixings. It is therefore recommended that stainless steel fixings are used for these timbers when used in damp conditions, for example cladding.

There are several actions that need to be taken by the timber supply chain to ensure a continued supply of hardwood for UK projects: • Woodland owners need to ensure their woodlands are managed over the long term to ensure a good supply of quality saw logs in the future. • Designers need to be educated on the alternative species to oak, to enable better specification of timber. • Clients and other specifiers need to have inclusive timber certification policies that allow timber from FSC, PEFC and GiB sources to be used. n

“With new planting rates in general decline, there is an inevitable need, sooner rather than later, to widen our palette of wood. So what are our options?”


alf of the UK’s woodland is conifer and half of that is Sitka spruce (Picea sitchensis). This oft-maligned non-native tree is by far the most important commercial species for the UK’s home-grown forest and timber industry. While available volume will decline over the coming years, as a result of planting rates over the previous decades, it will remain the most important timber species for many decades to come. That is, if we are not unlucky with tree pests and diseases. Recent experiences, especially the disease Phytophthora ramorum in larch, have focused attention on species diversification to improve forest resilience to pests, diseases and climate change. Alongside this there are changing public perceptions about what forests are for, and what kinds of species should be planted. With new planting rates in general decline, there is an inevitable need, sooner rather than later, to widen our palette of wood. So what are our options?

Grading properties Values are given for the three grade-wood properties that are most directly relevant to construction1: • bending strength • bending stiffness • density. The numerical values of these properties are based on fullsize testing to current standards (that is, timber with knots and other defects, not clear wood) at a reference moisture content of 12%. Because wood properties vary from forest to forest, tree to tree and even within a tree, the values are not precise. Where a range of values is given below, Edinburgh Napier University has sufficient data to state what approximate range might typically be found from a single sampling or processing shift. Where extensive test data is not available the values should be considered with the same inherent variability in mind. In line with modern design codes, strength and density are given as characteristic (fifth percentile) values, which is an expectation that overall no more than 1 in 20 boards will have lower values. Stiffness is quoted as the average (mean) value.2 >> www.trada.co.uk

Sitka spruce This comparison takes Sitka spruce (Picea sitchensis) (BS EN 13556 marking code PCST) as the benchmark, a species for which rapid growth and ability to thrive on sites where other trees struggle are distinct advantages. Contrary to popular belief, fast tree growth per se does not cause inferior wood properties, and the assumption that fast growth causes low density leading to low strength is, at best, unhelpfully incorrect. Napier has been researching Sitka since 2003, and now has a great deal of information about its properties, and how they are influenced by forest management and climate.3 The characteristic density of ungraded UKgrown Sitka spruce ranges from about 310 to 350 kg/m3, characteristic strength from about 13 to 18 N/mm2, and mean stiffness from about 7 to 9 kN/mm2. It is therefore the stiffness that tends to limit the structural grading, although when grading to C16 alone the machine reject is minimal. For this C16-graded timber, strength is actually higher than www.trada.co.uk

required for C18 and density is the least critical property (sufficient for C20), but still low enough to make Sitka’s high strength-to-weight ratio another one of its practical advantages. However, the extra strength and density cannot be considered in design without using the bespoke timber grade for UK spruce, C16+, established by Napier. With the right grading machine, yields of about 25% C24 with 75% C16 and minimal machine reject are achievable4, and while likely not economic on an industrial scale for primary processing, this may be viable for one-off projects. Grades of up to C27 and TR26 can be achieved in small amounts, which although impractical, illustrates the range of timber properties within a species from even a relatively small growth area such as the UK. Visual grading to BS 4978 assigns Sitka spruce to C14 and C18. The coefficient of determination (R-squared) between strength and density in UK-grown Sitka is only about 0.2, due partly to this species growing relatively dense but less strong wood in the early years of growth. >> Timber 2019 Industry Yearbook

Materials UK timber

Other species Norway spruce Norway spruce (Picea abies) (PCAB) is grown and processed together with Sitka in the UK and constitutes about 10% of the species combination known as ‘British spruce’ (WPCS). The sawn timber is practically indistinguishable and the wood properties are essentially identical, although the stiffness of Norway spruce is probably a little higher.5 The grading is therefore the same as Sitka. Although Norway spruce’s equivalence to Sitka is an advantage for markets, it does not add much to forest resilience or diversification. Larch Larch in the UK (WLAD) is a mixture of European larch (Larix decidua) (LADC), Japanese larch (Larix kaempferi) (LAKM) and hybrid larch (or Dunkeld larch) (Larix x eurolepis) (LAER). The wood properties of these species may be regarded as the same for home-grown timber, and larch hybridises so readily that distinguishing species on the tree is, anyway, rather tricky. The characteristic density of ungraded UK-grown larch ranges from about 400 to 420 kg/m3, characteristic strength from about 19 to 22 N/mm2, and mean stiffness from about 9 to 11 kN/mm2. As with Sitka and Norway spruce, the stiffness tends to limit the strength grading, but larch can reach C20 or C22 as a single grade with minimal machine reject. With the right grading machine, yields of about 30% C27 with 70% C16 and minimal machine reject are achievable. Grades of up to C35 can be achieved in small amounts. Density

is, again, the least critical property and even in ungraded material it is higher than the C40 requirement, although the R-squared value between strength and density is similar to Sitka at about just 0.2. Visual grading to BS 4978 assigns larch to C16 and C24.

Douglas fir Home-grown Douglas fir (Pseudotsuga menziesii) (PSMN) is, overall, quite similar in properties to UK larch, but is much more variable from stand to stand so the grading must be more conservative. This variability also causes the characteristic properties of the ungraded timber to be very low. The characteristic density of ungraded UK-grown Douglas fir ranges from about 360 to 450 kg/m3, characteristic strength from about 10 to 25 N/mm2, and mean stiffness from about 8 to 13 kN/mm2. For Douglas fir the strength tends to limit the grading and ungraded material does not meet the requirements even for C16. However, because the characteristic strength can be quickly increased by grading, the machine yield of C18 as a single grade is about 95%. With the right grading machine, approximate yields of about 65% C24 with about 25% C16 and 10% machine reject are possible. Grades of up to C40 can be achieved in small amounts. Once again, density is the least critical property, although it is lower than for Douglas fir grown in Europe. The density of UK-grown ungraded timber is at worst higher than the C27 requirement. Visual grading to BS 4978 assigns Douglas fir to C14 and C18, or C24 for large dimensions. The variability in the population means the R-squared value between strength and density is quite high at about 0.5, but the correlation can be non-existent within a batch of timber.

Scots pine Scots pine (Pinus sylvestris) (PNSY) is the only commercial timber conifer native to the UK. It is combined with Corsican pine (Pinus nigra laricio) (PNNL) in the species combination ‘British pine’ (WPNN). It finds good markets in non-structural products so Napier has little mechanical test data for analysis, although Forest Research is preparing a report with its data. Grading settings exist for the old bending type grading machines for C16 and C24, and visual grading assignments are for C14 and C22.

Lesser-used species The properties of species not currently used commercially are hard to state with any certainty since they depend so much on forest management and rotation length. For likely commercial rotations, the following can be expected5: • Noble fir (Abies procera) (ABPR): characteristic density ~320 kg/m3, characteristic strength ~15 N/mm2, mean stiffness ~8 kN/mm2 >> Timber 2019 Industry Yearbook

Materials UK timber

• Western hemlock (Tsuga heterophylla) (TSHT): characteristic density ~380 kg/m3, characteristic strength ~18 N/mm2, mean stiffness ~8 kN/mm2 • Western red cedar (Thuja plicata) (THPL): characteristic density ~320 kg/m3, characteristic strength ~16 N/mm2, mean stiffness ~7 kN/mm2. This makes these species roughly similar to Sitka in grading terms, although the stiffness of western red cedar is likely to be too low for good grading yields. Napier is currently researching some other likely conifer species for diversification: • Serbian spruce (Picea omorika) • Pacific silver fir (or amabilis fir) (Abies amabilis) (ABAM) • Japanese incense cedar (or sugi / Japanese red cedar) (Cryptomeria japonica) (CYJP) • Grand fir (Abies grandis) (ABGR) • European silver fir (Abies alba) (ABAL). These minor species constitute only a small proportion of the home-grown timber resource but could possibly become a minor component of an existing species combination such as ‘British spruce’. So long as the aspects of the timber that are important to manufacturing and construction are similar enough, the actual botanical species or genus is of little relevance to the user, especially considering the within species variability that is already addressed by grading.

Hardwoods The available volumes of hardwood in the near future are very limited compared to the conifers, but Napier is researching sycamore (Acer pseudoplatanus) (ACPS) and birch (Betula pendula/pubescens) (BTXX), which have potential for an eight-fold and a 13-fold increase in available volume respectively by 2045.6 Old visual grading assignments exist for BS 5756 that assign European oak (Quercus petraeaand robur) (QCXE) to D24, D30 and D40, and sweet chestnut (Castanea sativa) (CTST) to D24.

Wider variety needed The changing focus of British forestry, and the increasing demands on wood fibre for energy and as a feedstock for new materials in the desired future bio-based economy, make it inevitable that the timber industry will widen its focus from the present small number of commercial species. The good news is that this does not necessarily lead to significant changes for the end user. It is, after all, the performance of the timber that matters and not the appearance of the tree it came from. n www.trada.co.uk

Materials Metals and timber

“Different species of timber vary in acidity, so it’s important to specify metals with appropriate corrosion resistance and/or provide separating membranes or barriers between metal and timber, and/or specify a less acidic timber.”


etals that are used correctly in conjunction with timber will last the lifetime of a structure under dry conditions. But metals may be at risk from corrosion in wet or damp conditions. This risk can be minimised through correct specification, design, storage, construction and maintenance. The key agents of corrosion of metals by timber are moisture and acetic acid, a naturally occurring compound in all timber. Moisture may be present from rain, snow, condensation or vapour. Moisture content levels of 20% and over present a risk of metal corrosion. While acetic acid in timber can corrode metal, timber itself has good resistance to acids but is degraded by alkalis, which may form as a by-product of the corrosion of metal by timber. The combination of acidic corrosion of metal and alkaline degradation of timber can cause iron and mild steel fasteners and fixings to loosen, with a condition sometimes described as ‘nail sickness’ developing. Salts in seawater and some salts found in wood preservatives and fire retardant treatments will accelerate the corrosion of metals in the presence of moisture. The effects of corrosion of metals by timber are most pronounced where the two materials are in contact under one or more of these circumstances: • where the timber and metal are exposed to the weather, to a damp environment or to intermittent wetting • where the timber has been treated with a wood preservative or a fire retardant in the presence of moisture • where the timber is exposed to seawater or seawater spray. Specifiers should consider whether these situations are likely to arise and make appropriate choices of materials. Different species of timber vary in acidity, so it’s important to specify metals with appropriate corrosion resistance and/or provide separating membranes or barriers between metal and timber, and/or specify a less acidic timber.

Wood preservatives and fire retardants Preservatives containing metals as active ingredients carry a risk of corroding metal fixings. Manufacturers and suppliers of preservatives usually advise leaving the treated timber for at least 14 days before fixing to allow it to dry out. >> www.trada.co.uk

Materials Metals and timber

could cause corrosion problems. All metal fixings should therefore be of appropriate corrosion resistance and should be compatible with the timber species being used and with any preservative treatment specified.

Iron stain Iron stain is the result of a chemical reaction between iron and tannins or tannin-like materials in the timber that contribute to form iron tannin compounds. Commonly described as iron tannate, these compounds form a blue/black stain that can develop in damp timber in contact with ferrous metals Metal connections on Deal Pier. such as iron and mild steel. Photo: Price & Myers Iron stain is most commonly associated with oak, but also with sweet chestnut, makore, idigbo and kapur. Softwood species prone to iron stain include Douglas fir and western red cedar.

Metal connections on Deal Pier. Photo: Price & Myers

Some fire-retardant salts also promote the corrosion of metals and can raise the moisture content of treated timber. The potential of preservatives and fire retardants to corrode metals increases as the moisture content of the timber rises. The manufacturer of the wood treatment product must be consulted about the appropriate fixings to be used. There are other fire retardants with active ingredients that are not corrosive to metal fixings.

Seawater The potential for corrosion by timber of metals increases in the presence of salt water and salt water spray. For example, to counter this effect, austenitic stainless steel fixings for roof battens may be used in locations close to the coast, while galvanised steel fixings may be suitable for low-risk locations away from the coast.

Swimming pool halls Provided the appropriate measures have been taken, the moisture content of timbers in swimming pools will not generally be high enough to be the direct cause of corrosion in metal fixings. However, occasional but repeated wetting, and/ or condensation on glazing and chemicals in the atmosphere, www.trada.co.uk

Iron stain can arise where ironworks have been carried out near to the affected timber. It can be avoided by keeping ironworks and timberworks separate and/or by carrying them out at different times in the building process. >>

Dos and don’ts when using metals with timber • Where possible, use a timber species that is less likely to corrode metals. • Use metals, metal alloys or coated metals (for example, galvanised or powder-coated) that are less likely to be corroded by timber. • Separate metals from timber using drainage and ventilation gaps, inert materials such as plastic and/or impermeable membranes (for example, vapour control layers, dampproof courses impregnated breather membranes, bitumastic coatings and protective paint systems). • Avoid contact or close proximity between different metals. • Consult manufacturers of metal products to ensure the correct procedures are followed and that compatible materials are used. • Consult manufacturers of wood preservatives and fire retardants to ensure correct procedures are followed and compatible materials are used.

Acidity of timbers

Use classes

Some timbers are significantly more acidic than others. pH values range across a scale of 0 to 14, where a value of 7.0 is neutral, less than 7.0 is acidic and more than 7.0 is alkaline. The pH scale is logarithmic, so that a pH value of 4.0, for example, is ten times more acidic than a value of 5.0 and 100 times more acidic than a pH value of 6.0. In general, timbers with a value of 5.0 or more offer the least risk of corrosion to metals. The nominal pH value should only be used as a guide, however, as it can vary by two pH units, being influenced by factors such as soil conditions during growth and by the age of the timber.

Use classes classify timber according to the risk of fungal decay or insect attack resulting from wetting in service, and are defined in BS EN 335:2013 Durability of wood and wood-based products. Use classes: definitions, application to solid wood and wood-based products. These classes provide a useful reference for specifying metals and timber to be used together.

Metals Metals that are less able to form chemical compounds – described as ‘more noble’ – resist oxidisation and are therefore less corrodible. Those that form compounds more easily with other chemicals – known as ‘less noble’ or ‘base’ metals – oxidise and corrode more easily. Metals can be ‘blended’ to form metal alloys, or can be coated, to increase their resistance to corrosion. Austenitic stainless steel generally offers a reliable solution with a good range of products readily available. Often, however, the product may also be available in other metals, in metal alloys or in coated materials. Galvanised products, for example, may be preferred to austenitic stainless steel for shorter desired service lives for cladding fixings. More precisely engineered products such as nuts, bolts and other connectors may be available in more than one material. www.trada.co.uk

Conclusion In summary, there is no reason why metals and timber cannot work in harmony in dry conditions, so long as materials are specified correctly and that the right precautions are taken during design, storage, construction and maintenance. If there is any doubt, the manufacturers of metal components should be consulted when specifying metals for use with timber. n
