TRADA Foreword

An unprecedented year

How continuously changing circumstances have brought challenges and opportunities.


ovid-19 dominated 2020, overthrowing all previously made plans. TRADA has adapted fast and continues to do so as Government guidelines adjust to meet changing circumstances. In spite of the pandemic, I am thankful that there are several other updates to be made – be them industry developments or opportunities, comments on our personal fight against climate change, and updates on changes to the TRADA Board of Directors.

Industry opportunities The impact of the shutdown of building sites that occurred in spring 2020 directly resulted in a boost for the off-site technologies market, with more developers, local authorities and contractors focusing on integrating both panelised and modular housing solutions to speed up delivery. This shift change was last experienced post-World War II, which led to the prefab solution. Therefore, in the coming years we should expect higher demand and anticipate how timber can play its part. There is an increase in structural steel and cross-laminated timber hybrid office construction, especially in high-rise office designs, as the major UK developers move towards a more climate-friendly solution that proves to be both quicker in delivery and cost neutral.

Climate emergency TRADA has been broadcasting the environmental benefits of timber since 1934, so I won’t repeat what hundreds of pages of our resources already tell you. However, while organisations continue to rally against climate change on a wider scale, TRADA is now focusing its discussions on the critical role of climate literacy within university courses across the UK. Tabitha Binding, TRADA’s University Engagement Manager, continues to create excellent opportunities for students and lecturers – both to become more climate literate, and to incorporate it more fully into their educational curricula. TRADA is pleased to be working with – among others – Architects Climate Action Network and Anthropocene Architecture School, to bring discussions and decisive action to the people who matter. Many TRADA members are signatories of Architects Declare and Construction Declares, among others, which is fantastic. I cannot overstate how critical it is that we design buildings that


function as part of a larger self-sustaining system. It is one thing for individuals to challenge their behaviour, but we must also call for systemic change.

New appointees I am delighted to formally welcome Kelly Harrison, Associate Director at Whitby Wood, to the TRADA Board as a Director. It is a much-deserved position; her aspirations for and commitment to timber have seen her through more than 14 years in the industry, and a further year on the TRADA Advisory Committee (AC). I would also like to thank Alex Abbey, Partner at Cullinan Studio and supportive member of the AC, for stepping up to the role of AC Chair, a position left open by Simon Smith’s departure.

TRADA and the Timber Trade Federation In October 2020, the TRADA Board signed a memorandum of understanding to form a strategic merger of both TRADA and the Timber Trade Federation (TTF) in 2021. This is an historic step forward for timber in the UK and brings together two of the oldest and biggest names in timber. It will combine the lobbying and communications power of the TTF with the technical know-how, insight and design guidance from TRADA to make timber the first-choice product for designers across the country. I am looking forward to working with David Hopkins and other colleagues to make this a success from day one.

Summary 2020 was a pivotal year and I’m sure there will be many more challenges to come. We have not yet seen the end of Covid-19, nor the long-term impacts of Brexit, but – as Chairman of TRADA – I remain hopeful that the timber industry may seize the opportunity to grow and take root. n

TRADA Review of the year

2020: A year for online events Rupert Scott delivers a round-up of TRADA’s activities from the past 12 months.

3It would be TRADA's last in-person event was Futurebuild in March 2020

impossible to review the past year without mentioning Covid-19 and how it has changed the way we work. As a result of the restrictions, TRADA’s last in-person event was Futurebuild in March 2020, which marked the release of the long-awaited Manual for the design of timber building structures to Eurocode 5 2nd edition.

3When Covid-19 relegated many construction professionals to furlough or self-isolation, we began work on the Learn with TRADA email series. Over several months, we released emails focused on varying subjects, each collating relevant reading, free downloads and handy discounts in the TRADA Bookshop. We have delivered 18 Learn with TRADA emails, and have had tremendous feedback. These emails have continued into 2021, with further goodies to be added.

TRADA University Engagement Programme

Challenges, the curriculum and climate literacy: a bright future for timber and engagement Tabitha Binding, TRADA’s University Engagement Manager, reports. TRADA University Challenge 2020 Supported by major sponsors STEICO and Arnold Laver, sponsor Stora Enso, and supporters Programme for the Endorsement of Forest Certification UK, Passivhaus Trust, Western Timber Trade Association and Wood for Good, the 48-hour competition, which took place 17–19 February 2020, saw 58 students from universities across the UK gather at Cardiff University to compete to design, cost and engineer new homes. The brief given by Wales & West Housing Association for a large rural site at Adams Drive, Narberth, Pembrokeshire, laid out real-life constraints for the students to address: affordable housing that is low-carbon, energy and water efficient, climate resilient, healthy and desirable. Each team consisted of student engineers, architects, architectural technologists, quantity surveyors and landscape architects, and received hands-on support from pioneering design professionals and industry members, including judges from Mikhail Riches, Cullinan Studio, Stride Treglown, Ramboll, Buro Happold, Entuitive, Gardiner & Theobald and PLAN:design. Posters and models from the four winning teams displayed at Futurebuild in March attracted lots of attention and so lectures, talks and live projects were talked about, booked and then... Covid-19 took everything from on site to online almost overnight.

The curriculum New curriculum guidelines for the development of engineering degree programmes, issued by the Joint Board of Moderators in March 2020, included a requirement to integrate sustainable development into existing teaching and learning, and stipulated that students must graduate aware of climate change, the low-carbon agenda and the effect of material choices. This has opened the door to timber being taught on a par with other construction materials. TRADA has consequently drawn together an online working group of engineering lecturers and professionals from across the UK to address the teaching of timber.

Prior to the engineering working group being set up, a pilot of the module Structural tests on timber beams – developed by Dr Zhongwei Guan and Dr Jürgen Hackl at the University of Liverpool’s School of Engineering – took place. Working in small teams, 130 second-year engineering students undertook the module enabling them to understand the structural behaviour of timber beams with different grades and to learn how to conduct a structural test to obtain key parameters and characterise structural performance. Timber was donated by the North West Timber Trade Association and James Jones & Sons Limited. The architecture curriculum is in the process of being updated with tensions developing around the call for more technical climate literate knowledge integration. Students, tutors, lecturers and professionals under the umbrella of Architects Climate Action Network (ACAN) are campaigning to embed three aims into the curriculum: decarbonisation, ecological regeneration, cultural transformation.

Climate literacy To encourage design students and their lecturers to become climate literate and understand how they have the power to greatly

TRADA University Engagement Programme

reduce the emissions of greenhouse gases in the construction sector, TRADA ran a series of sold-out online workshops with the Anthropocene Architecture School, about Climate Literacy and the Built Environment, supported by ACAN student members. Participants from 47 universities took part, which led to a significant increase in TRADA membership and a big increase in students incorporating timber into their design projects.

A bright future Covid-19 brought about uncomfortable changes, eroded certainties and challenged preconceptions. And yet 2020 was hugely positive, with increased collaboration and a willingness for academia, industry, professionals and associations to come together, to encourage, enthuse and educate. n


Designing timber structures builds knowledge incrementally in a series of chapters and begins by exploring the material of timber itself, including its sustainable credentials. Chapters

Timber structures Wood Awards winner

Outstanding and sustainable new homes Winning both the Gold Award and the Private Award in the 2020 Wood Awards, The Rye Apartments showcase how timber can be used to create efficient, high-quality and low-carbon buildings.


acing Peckham Rye Park in South London is a new development of ten apartments which demonstrate how the use of timber can create homes that are sustainable, efficient to build and with interior spaces of exceptional quality. The apartments have a structure of cross-laminated timber (CLT) which is exposed on the internal walls of the apartments, creating warm and tactile interiors filled with light from generous windows. Tikari Works acted as architect and – unusually – as both client and main contractor for the project. Practice partners Ty and Nicola Tikari had previously acted as client, developer and main contractor for their own home, the award-winning Pocket House, subject of a TRADA Case Study in July 2020.

The project The practice acquired the prominent corner site, containing a dilapidated two-storey building and four garages, with the intention to create, as the architect explains: ‘exciting, sustainable homes full of detail, craft and delight. The project was driven by two key considerations – how to design spaces which resisted standardised or default positions within housing design, and how to create an efficient building with the minimum amount of material, embodied carbon and cost. To this end, the choice of timber as a primary material within the project was key to achieving these objectives.’ The ten apartments are set in two blocks, one of three storeys and one of four storeys, which face each other on a corner site opposite the popular park. Red brick Victorian houses and larger apartment buildings lie alongside, and the two blocks relate to this neighbouring context in form and scale. They are clad with red clay shingles that reflect the colour and texture of adjoining brickwork yet, because they extend seamlessly over both walls and roof, the shingles create an urban composition that appears both new and familiar. A concrete plinth at the base resolves changes in level and encloses bin and bike stores. >>

The timber structure Richard Mayo, structural engineer and associate at Webb Yates Engineers, describes the structure: ‘The use of CLT as the primary superstructure material had a number of benefits for the scheme. It enabled us to take advantage of its lightweight nature and provide a reduced foundation scheme which wouldn’t have been achievable with a heavier structure. The construction programme of the superstructure was also very short, with each block being built in a couple of weeks using a mobile crane positioned between the blocks to lift all the panels into place. With the sloping topography of the site, the concept design was to use a concrete substructure to provide a ground slab and external retaining walls. These walls were then used as a plinth for the superstructure to launch the perimeter CLT walls above ground, with internal CLT walls extending down to ground floor. The concrete faces have been left exposed which provide an aesthetic contrast with the also exposed CLT walls and soffits.

Photo: Jack Hobhouse

The accommodation ranges from one-bedroom apartments with garden plots in the space between the blocks, twobedroom apartments with terraces facing the park and three-bedroom two-storey apartments on the upper floors and within the pitched roof spaces; the rooms open out to terraces on both sides.

Timber 2021 Industry Yearbook

The internal layouts and geometry of the two apartment blocks enabled the CLT to be used in an efficient way with a clear primary span between the perimeter walls and the spine/party wall, while the internal walls within the apartments were also used as loadbearing and provided additional support to the floor panels. This resulted in 200mmthick floor panels and 100mm-thick wall panels throughout both blocks. The apartment layouts also gave an opportunity to show how CLT can be used effectively with changing floor plans either by utilising the walls as deep beams, or with light transfer framing. Where transfer structures were required, the use of glulam beams and columns was prioritised, and working with Tikari Works we developed a design solution to suit each apartment

Timber structures Wood Awards winner

which incorporated these elements into the internal walls to avoid compromising the spaces with additional structure. As a result of the use of CLT, the primary structure has a net negative embodied carbon with the sequestered carbon in the timber offsetting the amount of carbon produced for the materials used in the substructure and superstructure.’

The design of the interior spaces The apartments’ interiors are designed to be clean and simple, using a limited palette of natural materials to minimise visual clutter and create spaces that act as a backdrop to furniture and daily life. Internal walls, ceilings and staircases are all of visual quality spruce CLT. The internal walls and ceiling surfaces were treated with a site-applied coating that achieves Class 1 and Class 0 fire resistance and spread of flame; it has a 10% white tint to prevent the timber yellowing over time due to UV light. The CLT floor panels – which are exposed on the underside as the ceiling of the apartment below – are overlaid with underfloor heating and floating floors for acoustic deadening between apartments. The floors are finished with white-lacquered ash boards and terrazzo tiles. Bathrooms and halls are floored with red quarry tiles and services are housed in dropped ceilings

lined with delicate spruce timber strips. Other services were co-ordinated into pre-routed channels in the prefabricated CLT structure or routed within the floor space. Within the timber-lined living spaces are cupboards, shelves, cooker hoods and kitchen units made of CNC grooved 18mm three-layer spruce ply boards and worktops made from recycled paper. The apartments on ground and first floors are divided by the staircase/lift core and by a central CLT party wall comprising twin 100mm CLT wall panels; the air gap between them is filled with a mineral wool acoustic barrier.

Sustainability The extensive use of timber as a renewable resource and carbon store was a key consideration in minimising the embodied carbon of the development, allowing the building to satisfy cradle-to-cradle principles of sustainability. A total of 227 tonnes of carbon dioxide has been removed from the atmosphere and stored in the timber structure over its lifetime. The length of time required to grow the same timber again in the Austrian forest is less than two minutes. The thermally efficient ‘fabric first’ CLT superstructure is close to Passive House standards of airtightness; this was achieved by careful detailing and rigorous management on site by the in-house design and construction team. The CLT frame is wrapped with 150mm of non-toxic and non-combustible mineral wool insulation overclad with the rainscreen of red masonry shingles. The use of CLT prefabricated components reduced construction time, minimised waste and enabled dry construction techniques to be used extensively. In addition to the use of timber, energy-saving features include photovoltaic panels, whole-house heat recovery mechanical ventilation and high-performance solar control glazing, all set within a highly airtight envelope. n

Timber structures Spotlight on: Sustainability

“Using wood in construction to displace high-carbon materials such as cement and steel is one of the most effective ways to use limited biomass resources to mitigate climate change.”


n an attempt to slow climate change, the Government has set targets for the UK to reach net zero by 2050.1 If we are to have any realistic chance of reaching these goals in time, we must act now.

While there is no quick fix to addressing the climate emergency, the forest and wood-based industries have a crucial role to play. For the UK to reach net zero, we must prioritise and promote increased tree planting and greater use of wood products. Indeed, in its 2019 UK housing: Fit for the future? report,2 the Committee on Climate Change said: ‘...Using wood in construction to displace high-carbon materials such as cement and steel is one of the most effective ways to use limited biomass resources to mitigate climate change...’ It also stated that the construction industry must focus on the whole-life carbon impact of new homes, including embodied and sequestered carbon.

How timber can achieve net zero Using timber in construction helps to reduce carbon dioxide (CO2) levels in the atmosphere and slows climate change in three simple ways: • Trees capture harmful CO2 from the atmosphere and store it as carbon. • Sustainable forest management with timely harvesting and restocking leads to continued capture of CO2 . • Using timber for construction instead of more CO2 -intensive materials means carbon is stored for at least the lifetime of the building, and often longer when reclaimed wood is used for ‘second life’ products.

Choosing structural timber to reduce embodied carbon According to the Institute of Structural Engineers, embodied carbon can contribute 10% to 20% of a building’s total carbon footprint.3 In a typical new office building, 50% of the embodied carbon is in the structure alone. This can be reduced by choosing timber for a building’s structure. >> www.trada.co.uk

Timber 2021 Industry Yearbook

Timber structures Spotlight on: Sustainability

Embodied, operational and sequestered carbon Embodied carbon, also known as embedded carbon or

carbon capital, is defined by the UK Green Building Council as ‘the total greenhouse gas emissions generated to produce a built asset’.4 This means knowing how much CO2 is emitted from extraction, processing, manufacturing, transportation and assembly of every building product used.

Operational carbon is often measured alongside embodied carbon. It is the collective CO2 emissions produced for a building to run, from the energy, heating, cooling and ventilation systems through to IT equipment and lighting.4 Sequestered carbon is the amount of CO2 that is stored in the earth, in oceans, in trees and in plants. Trees ‘capture’ carbon during photosynthesis as they grow and this remains stored inside them even when they are felled and turned into wood products and materials. This means that buildings become a carbon store when their structural frame, insulation and interiors are made from wood.

One example is at Republic in East India Dock.5 Two office buildings, the Import Building and the Export Building were extended and refurbished together with the surrounding public realm. Architect Studio RHE worked with structural engineers Heyne Tillett Steel to expand both buildings with internal timber frame structures constructed from exposed glued laminated timber and cross-laminated timber (CLT). The carbon stored in the new structures equates to 404 tonnes at the Export Building and 460 tonnes at the Import Building. This means that for the buildings’ lifetimes until demolition, the new structures store more than 1.5 times carbon than used in their construction.5

Ways to reduce embodied carbon include: • specifying natural and renewable materials such as timber, particularly for the structure • specifying alternatives to cement mix such as lime and fly ash • checking the Environmental Product Declarations (EPDs) of a product for details on its carbon footprint (wood products can be checked using the Lifecycle Database)6 • using off-site construction to minimise waste, reduce build time and improve quality • applying circular economy thinking, particularly reusing materials or using fewer materials. This is key for the end of a building’s life.

The challenge of reducing operational carbon When we think about creating more energy-efficient, environmentally friendly buildings, we often focus on switching to renewable energy sources. Although this is one part of the solution, if we continue to build poorly insulated and ventilated homes, the demand on renewable energy sources to heat and cool them will in itself be unsustainable. Homes also need to be as fabric efficient as possible.

To become more fabric efficient, Passivhaus principles are a good place to start. By designing airtight homes to Passivhaus or near-Passivhaus standards, houses are naturally heated and ventilated using air and ground source heat pumps and mechanical ventilation systems. >> Timber 2021 Industry Yearbook

Timber structures Spotlight on: Sustainability

A report published by the BioComposites Centre at Bangor University concluded that using timber frames rather than masonry can reduce carbon embodied emissions by around 20% per building.9 When CLT is chosen in place of concrete structures the effect is even greater, with carbon embodied emissions reduced by around 60%. As an industry, we already have the technology, knowledge and skills to make a dramatic difference to the impact that the built environment has on climate change. While the move will not always be easy, the negative impacts of doing nothing, adapting too slowly or merely tinkering around the edges will remain with us for generations to come. n

Passivhaus is not just for self-builders, as demonstrated by the RIBA 2019 Stirling Prize winning Goldsmith Street.7 Architect Mikhail Riches designed a mix of houses and flats for this Norwich City Council social housing development. Constructed from insulated timber frame panels that were manufactured off site, the homes were built to Passivhaus standards, with the result that the occupants enjoy sunny, light-filled homes and fuel bills of just £150 per year. Another award-winning example is the Leeds Climate Innovation District.8 Designed by White Arkitekter and developed by sustainable property company Citu, it combines sustainable design and construction techniques to deliver low-carbon living for city-centre residents. The properties are ten times more airtight than UK Building Regulations require, coming close to Passivhaus standards.

Why wood CO2ts less Those working in the built environment are aware of the impact the construction industry has on the planet. Drawing on limited resources, labour-intensive practices and creating buildings that are high in embodied and operational carbon are having longterm effects. Therefore, opting for more sustainable building materials that capture and store carbon, such as wood, needs to become normal practice. www.trada.co.uk

Timber structures Spotlight on: Sustainability

“During its life a tree will capture and store carbon in its structure. If the timber is used in construction after it is felled, this carbon remains locked away rather than being released during the process of decay.”


he overriding benefits of using timber in construction have increased its recent use in the UK construction sector. A combination of climate action groups and rising carbon dioxide (CO2) pollution levels have influenced governments worldwide to consider more sustainable construction methods and many are now issuing targets on how to achieve zero carbon within very restrictive time frames. Globally, building and construction are responsible for 39% of carbon emissions.1 In France it has been announced that all new public-funded buildings must contain at least 50% wood or bio-based materials by 2022 in an ambitious plan for a greener urban life. Why wood? Wood is multifunctional, strong and insulating; it sequesters carbon, helps to reduce operational carbon and is a beautiful natural product.

Wood as a raw material While the majority of European-sourced timber comes from well-managed forests, offering sustainable and recyclable products, even timber is a precious resource. It is therefore critical that the whole tree is used at some point during the manufacturing process. Wood fibre insulation is produced from trees that are felled either from forest thinning or coppicing programmes that were never destined to grow to full size, which is a great example of how ‘waste’ wood can be valuable. The bark is removed and used as a biomass energy source while the rest of the tree is ground to produce wood fibres for insulation (or for other products such as fibreboard).

Thermal performance and wood Thermal performance is often explained as how well a home retains heat. This can be the defining factor between a freezing cold home in the winter or a warm and cosy one. However, that statement only defines thermal performance in terms of retaining heat, with no mention of the need to keep excessive heat from entering a building and overheating it. It takes more energy to cool a building using air-conditioning units than it does to heat it. >> www.trada.co.uk

Timber structures Spotlight on: Sustainability

Insulation should be designed so that it allows a building to provide year-round thermal comfort. The natural properties of wood make it an excellent insulant; it has low thermal conductivity, high density and high specific heat capacity. The UK Building Regulations focus on the U-values achieved as the main measure for efficiency. However, heat can travel by convection, radiation and conduction. Conduction is the focus on the building fabric. Do two walls or roofs with the same U-value perform the same way when considering other factors of thermal performance? No. By using the right materials for the fabric of the building, summer overheating can be controlled, better indoor air quality can be achieved and occupants receive better year-round comfort, as well as reduced energy consumption and bills. The control of summer overheating is commonly known as ‘phase shift’.1 A correctly designed timber structure, incorporating wood fibre sheathings and insulations, is just one way of achieving a better-performing building. This technology is already widely used in other countries, so how can its use be increased in the UK?

Breathability / vapour open All buildings should offer a comfortable indoor environment and ensuring good indoor air quality requires the right balance between airtightness, vapour control and breathability. It is possible for a building to be both airtight and achieve acceptable air-exchange levels as well as being ‘vapour open’ and breathable.

STEICO Zell air injected wood fibre insulation to a timber frame structure. Photo: STEICO

Correctly detailed building fabrics using wood fibre materials allow moisture, which can be detrimental to human health, to pass through the structure of a building without affecting its integrity. A vapour open external layer ensures that no moisture is trapped within the frame, which is good for both the wellbeing of the homeowner and the structure of the building.

Passivhaus principles Passivhaus is the leading international design standard for low-energy, comfortable, high-quality and affordable buildings. By using timber as part or all of the main structure and incorporating wood fibre insulation, some of the key Passivhaus principles such as super-insulation and thermalbridge-free construction can be achieved while also ensuring the lowest possible impact on the environment.

Sequestered carbon Carbon sequestration or carbon dioxide removal (CDR) is the long-term removal, capture or storage of CO2 from the atmosphere. This means that during its life a tree will capture and store carbon in its structure. If the timber is used in construction after it is felled, this carbon remains locked away rather than being released during the process of decay.

Instead of carbon offsetting, why not use more of the materials that can have ‘negative’ carbon when calculations are made? Using more timber products in construction automatically removes CO2 from the atmosphere, if you ensure those >> Timber 2021 Industry Yearbook

products come from a sustainable source where felled trees are replaced at least 1:1. If the UK implemented the same legislation as the French Government, an immediate impact would be made in sequestering more carbon in buildings, creating a positive impact on the climate crisis.

Operational carbon If a dwelling is designed with energy efficiency in mind, using the principles of a fabric-first approach, which considers the components and materials that make up the building fabric before the use of mechanical or electrical services, timber-based products can have a double effect when it comes to carbon. When a building is designed and built using natural materials that offer good year-round thermal comfort, there are not only benefits from the ‘locked in’ carbon of the structure but also energy consumption, which assists in the operational carbon produced in the everyday running of the building. With the probability that from 2025, new homes in the UK will not be permitted to use gas as a primary source for heating, combined with the rise of electric vehicles, there will be a huge burden on the electrical grid. Therefore, anything that can be done to reduce energy dependency, such as an efficient fabric-first approach in construction, will play a key role in future housing solutions. www.trada.co.uk

Summary The natural properties of wood-based materials, be it in construction or insulation applications, should make them an automatic choice for the UK construction sector. They provide strong, versatile and resilient structures that ensure high levels of year-round thermal comfort. Wood is also sustainable, recyclable, well-resourced and managed, and stores carbon at source. n

Changing the narrative: Biodiversity, Forestry and Wood report

Eleanor Harris outlines the findings from the Confederation of Forest Industries (Confor).


ntil now the forestry industry has had few resources to counter accusations that conifer forests planted for softwood production are ‘barren’, ‘lifeless’ or ‘biodiversity deserts’. Therefore, to draw together the evidence that forestry is essential and sustainable, and assess the gaps in research, Confor prepared its new report Biodiversity, Forestry and Wood.1

and spiders from pitfall traps, or shaking them onto sheets; crunching data on woodcock or dormice submitted by thousands of volunteers. Hundreds of comparative plots – old, young, native, exotic, managed, unmanaged, open, afforested – reveal the difference forests and their management make to wildlife. Previously, none of this work was in the public domain to inform policy and practice.

How the results were acquired and what they mean

The UK’s wood-producing forests are far from lifeless and harvesting far from disastrous. Working conifers support abundant life, and have allowed threatened forest specialists such as wood ant, crossbill, ferns, fungi and lichens to expand. Some forest species only live on native trees, which is why it is important that all working forests include a native component. Yet the difference between native and nonnative was far less marked than expected. For most wildlife, it is the presence of a forest that is important (generally the bigger the better) and sustainable, professional management matters more than tree species.

The results cited in the report represent thousands of hours spent by ecologists listening for birdsong and bats; counting plants in squares and butterflies along lines; fishing beetles

Standardisation Many of the studies cited in the report played an important policy role in informing and assessing the development of the sustainable forestry framework – the UK Forestry Standard (UKFS).2 This standard ensures that woodland creation and management benefits biodiversity as rapidly and deeply as possible. Pockets of native broadleaves and open space among the conifer crop increase habitat value of the whole forest, as does retention of deadwood and unharvested areas.

Timber 2021 Industry Yearbook

Standards for drainage and harvesting ensure forest management improves rather than damages freshwater habitats, and avoids undue disturbance to wildlife. UK-planted forests have always delivered biodiversity gain, although in the past mistakes could also cause loss. For the past 30 years the UKFS has ensured that siting, design and management of forests delivers resounding biodiversity benefits.

Timber structures Spotlight on: Sustainability

favourable policy environments that encourage landowners to plant trees on better land than in the past, carbon capture is accelerated through faster tree growth – off the scale of current carbon calculators. The importance of wood use to replace carbon-emitting materials such as steel, concrete and plastic is increasingly well understood. So, too, is the importance of growing sufficient timber in forests planted to meet this need. Otherwise, pressure to exploit undisturbed natural forests, damaging their valuable carbon and biodiversity stores, will increase. The report cites figures showing that globally, wood produced from planted forests reduces harvesting of natural forests by 26%, and planted forests are very efficient: they comprise around 7% of global forest cover but contribute 46% of the wood we use. Future timber demand is expected to quadruple by 2050, so the need to increase our supply is urgent.

Report findings Biodiversity case studies Biodiversity, Forestry and Wood is not just a literature review. It also incorporates case studies from Confor members, giving a voice to woodland owners, managers and contractors who work in the forests across the UK, and who see and appreciate its wildlife on a daily basis. John Little, for example, is an experienced Forest Manager with Tilhill who has worked in Argyll for 30 years. He has seen hen harriers and sea eagles colonise as forests mature, along with red squirrels and signs of their predators, pine marten and wildcat. Walking forest fence lines he is struck by the contrast in birdsong between forest and the rough grazing it replaced. His new woodland schemes and harvesting/restocking plans ensure microhabitats such as ancient woodland, wetland and species-rich grassland are identified, protected and expanded in forest designs.

Timber production The report also explores the wider context for growing timber. Evidence of the carbon benefits of the UK’s woodproducing forests is increasing. With better silviculture and genetics, and healthy timber markets and more www.trada.co.uk

The UK, with its low forest cover, strong demand for wood and excellent climate for growing trees, is well placed to tackle this global hunger for the green gold. In the past, this has often been perceived as a choice involving sacrificing forest biodiversity for the sake of an essential commodity. But not only can a working forest sustain a rich ecosystem of forest wildlife, the active management paid for by its timber production is also intrinsic to its health and resilience. Timber doesn’t just build homes for people, it sustains habitat for biodiversity. n

Architects Declare: one year on

Kat Scott provides an update on the progress so far.


n 2019, 17 Stirling prizewinning architecture practices acted as founding signatories to UK Architects Declare Climate and Biodiversity Emergency. There are now more than 1,000 signatories and the list continues to grow. Each of these companies has committed to enact change in line with the initiative’s 11 declaration points.1 The underlying problem the architecture profession faces is that, while knowledge and skills already exist to make the change necessary to mitigate these crises, there has not been a collective urgency to incite that change. Accelerating this recognition can be achieved by sharing knowledge in a non-competitive manner across the profession, by changing mindsets in the public and industry alike, and by recalibrating the goals of the system.

A year of Architects Declare

Inaugural event

In the 18 months since Architects Declare was founded, this landmark initiative has inspired other disciplines and countries to establish sister campaigns under a wider banner of Construction Declares Climate and Biodiversity Emergency. Under the UK Construction Declares umbrella there are now declarations for structural engineers, building service engineers, civil engineers, contractors, landscape architects and project managers.

In November 2019, before anyone had heard of Covid-19 and when it was still possible to meet in large numbers, Architects Declare held an inaugural event at the Battersea Arts Centre with more than 350 attendees. Here, exemplary speakers such as Kate Raworth, author of Doughnut Economics, and Jeremy Lent, author of the Patterning Instinct, shared their knowledge with attendees, after which group discussions were facilitated with the support of Architects Climate Action Network (ACAN) volunteers. A live ‘slido’ was held to gauge opinions on a range of topics, from supporting a Green New Deal, to working with clients who may not operate in line with the declaration commitments. All of the day’s events were video recorded and are now part of a range of resources on the Architects Declare website.2 >>

Globally, other countries have set up their own iterations of these initiatives, with a total of 5,800+ companies worldwide now part of this movement. This includes declarations in Australia, Canada, the US, Ireland, Singapore, South Africa and Germany, to name just a few. www.trada.co.uk

Timber structures Spotlight on: Sustainability

Feedback survey In spring 2020, Architects Declare conducted a survey of signatory practices to gauge how they felt they were faring with enacting the level of change the declaration commitments imply. The survey also sought to receive feedback on what the signatories wanted the initiative to become in the future. Pleasingly, 80% had significantly or somewhat changed; although it was clear there were particular areas of the declaration for which practitioners felt they needed more support. From this, more resources were developed for signatories targeting these challenging areas. These resources are: 1. Running meetings across ten UK regions for practices to share ways of implementing the declaration and practical knowledge with each other. These ten regions are now meeting regularly. The frequency and agenda for those ongoing meetings are self-led. 2. A soon-to-be launched practice guide that has been developed by the Architects Declare working group of volunteers, with expert review and input. 3. A new website that has resources from all Architects Declare events, including videos of the Battersea Arts Centre conference and the embodied carbon event.

The Steering Group also tries to tie links across to other initiatives, such as the London Energy Transformation Initiative (LETI), the Architects Climate Action Network (ACAN), the Edge3 and a range of professional institutions. As the Architects Declare signatory list has expanded, so too have the administrative efforts required to keep the communications between signatories flowing and to create the kinds of resources and support that the signatory practices highlighted they needed in the first survey. The Steering Group has tried to grow the organisation’s structure, establishing a working group of volunteers to help with the generation of resources (including a guide for practices who have declared a climate emergency to enact the declaration through their daily work), helping to write consultation responses and supporting the work of the initiative.

Increasing support Architects Declare has relied on support from those working closely to it, but has now issued a plea for contributions from its signatories, asking for £20 per qualified architect working in any signatory practice as a suggested amount. There are plans for the initiative to become a charitable organisation to make this a more formal part of the structure in the future.

The Steering Group The Architects Declare Steering Group meets on a fortnightly basis as a whole team, forming sub groups to progress work on priority tasks in between meetings. Much of the work involved in setting up sister initiatives both here in the UK for other professions, as well as internationally, has been undertaken by this group – in particular by Jacqueline Wheeler of Haworth Tompkins. The original instigators of Architects Declare are endeavouring for the Steering Group to be as diverse as possible in terms of age, gender, background, race and profession, and continue to work to improve this.

Regional meetings In addition to the working group, there are now regular regional meetings, where signatory practices from across the Construction Declares family are invited to form groups based on where they live or work. The first of these events has commenced, with the North East and North West discussing engaging with clients and the Midlands discussing easy wins in sustainable design, with each regional group establishing its own agenda for the event. It is hoped that professionals will benefit from meeting likeminded individuals to galvanise local initiatives and to form support networks to help meet the declaration commitments.

Actions in 2021


For Architects Declare, the next major milestone will be the postponed UN Climate Change Conference (COP 26), where it is hoped that construction and the built environment will be integral to the discussions. This is particularly important given the large impact these aspects have on the industry meeting its climate targets, with 40% of carbon emissions arising from the built environment. n

Structural timber: delivering quality and sustainability assurances The Committee on Climate Change has advised the Government to use the coronavirus crisis as a catalyst for reducing the construction industry’s carbon emissions and called for ministers to seize the opportunity to make the industry greener. Andrew Carpenter discusses how structural timber systems can help the UK construction industry deliver both quality and sustainability assurances.


he world has woken up to the detrimental impact that we are having on the planet. Now is the time to invest in building in timber for not only safeguarding the environment and reaching net zero carbon targets, but also to deliver predictability of quality and performance. This is a massive opportunity for the UK to make a sizable change and opt for more sustainable building technologies. There is now real positivity around our sector. Structural timber systems are acknowledged as one of the optimum construction solutions in the battle to reduce carbon emissions.

Reducing carbon emissions Trees are at the heart of the climate change debate. Once carbon sequestration was a natural phenomenon only understood by scientists, but this has changed and terms such as ‘carbon sink’ are commonly used in construction. Commercially managed woodlands sequester a third more carbon dioxide than wild forests – so the growing of timber for use in construction is vital in the battle to reduce carbon emissions.

Build process Modern timber frame structures are precision-engineered, strong and durable. The build method relies on a factory-manufactured timber frame as a means of structural support – carrying the loads imposed by the floors and roofs – before transmitting them to the foundations. The foundations for timber frame structures can be built at a lower cost and less environmental impact due to the lightweight nature of the structure. www.trada.co.uk

Timber frame construction uses factory-manufactured wall panels, floor panels and roof panels. The systems used are classified as either open panel, closed panel or structural insulated panels (SIPS). In open panel timber frame structures, the open panel system provides the structural frame, to which site-installed insulation, services and plasterboard elements are added. In closed panel timber frame buildings, the structural frame is the same as an ‘open panel’ construction, but includes factory-fitted insulation and inner sheathing boards to close off the panel. Finally, the SIPs building method uses timber panels, which are bonded to insulation to provide structural strength.

Progress Around three quarters of all new homes in Scotland are built using structural timber, but England is lagging behind with just a quarter of all new homes being built using structural timber. >> Timber 2021 Industry Yearbook

“The past 20 years has seen a welcome return of timber being used in modern building design, and this is accelerating. Engineered timber allows large spans, and an infinite variety of forms, for both public buildings and domestic architecture.”


n the Middle Ages, cathedral builders acted as their own engineers, and the master mason and master carpenter would be wholly responsible for the execution of the build. They learned from their mistakes and we have the benefit of learning from their success – the failures didn’t survive. The lantern tower at Ely Cathedral, completed in 1334, is one of the greatest engineering feats of its time. The structural design principles for such historic timber frames clearly pre-date modern building regulations. A tried and tested design can be proved on the basis of precedent, and a Certificate of Approval from a specialist engineer is perfectly acceptable. This method is widely used in the design of such structures, such as this crown post roof for a Buddhist monastery.

Timber today Tradition aside, the past 20 years has seen a welcome return of timber being used in modern building design and this is accelerating. Engineered timber allows large spans, and an infinite variety of forms, for both public buildings and domestic architecture. It is promising to see that there are increasing numbers of structural engineers and architects who specialise in working with timber and encourage its use. This article explores the ways in which timber designers and engineers can work together by outlining the main factors in that relationship. Most successful projects are forged by teamwork and collaboration.

1. The fundamentals There are three principles that inform a successful project: design, structure and buildability. If the architect and engineer speak for the first two, the timber designer can offer other allimportant elements: • value for money • eliminating redundancy • making it buildable. Now that most designers use 3D modelling it is easy to forget that building in this way has limitations not always evident on a screen. It is then that the timber frame designer can help. >> www.trada.co.uk

an idea of the form, scale and content of the structure, and a conversation that concludes, ‘Yes, that works’. The team can then move forward, get the consultants properly appointed and begin the second stage. If the conversation concludes that it does not work, it is time to rethink.

5. Specification

2. Off-piste It is not uncommon for the carpentry team to make suggestions that depart from the specification of the project engineer. However, engineers (or more correctly their professional indemnity insurers) understandably don’t like sharing design responsibility. It is therefore important to draw a line between the two disciplines and agree who does what. Typically, the carpentry team would be subcontracted to design the timber element of the building and engage their own engineer to justify it.

It is important to forge a relationship with the consultant engineer at an early stage. The engineer might come up with specifications that demand a certain performance from the material, but the carpenters’ experience may tell them it would be unachievable. In this case, a series of conversations can quickly narrow down the options and come up with a workable specification. Solid timber is anisotropic in its nature, which is to say that it behaves differently in its three planes: radially, tangentially and along the grain. An engineer may choose the option not to use solid timber but prefer to specify engineered timber because this is more predictable. However, nothing should be ruled out when selecting the right material.

6. Procurement

Structural timber frame design is usually a straightforward process – it is the interface with the rest of the building that causes the most discussion, for example the specification for the building envelope. Although not in the remit of the structural team, it affects the design and performance of the structure, and engineers must allow for the dynamic loads. In addition to structural calculations, engineers need to check serviceability – the effects of creep, deflection and movement must be accounted for if they create the possibility of damage to surface materials or finishes.

When supplying a batch of solid timber, particularly of unusual specification, any good timber merchant should always ask what the material is to be used for. The end use of the material is critical if the right species, grade and quality is to be offered, and feedback from the producer is invaluable. It is tempting for the architect or engineer to specify a high grade of timber, just because such grades are listed. However, it might not be suitable, or even available, and it takes experience from the carpenters to manage the procurement. Timber selection is a certain skill that can make or break the success of a project. It may be considered a poor use of resources to specify the highest grade of timber where a lower grade would do perfectly well.

4. Intuition

7. Grading

In terms of specialist timber engineering, a two-phase approach works well. The first stage begins early in the process, when the design intent is known but no details are developed. An early meeting should establish the general structural principles, along with buildability and affordability. ‘Intuitive engineering’ means you have an outline sketch,

There is more to grading and specifying timber than the table of mechanical properties used by the structural engineer, and the carpentry team can inform this process. They know that timber conversion has a big effect on strength, durability and movement, and can predict the likely shrinkage and movement of each component. The rate of growth can be specified, >>

3. Interface

Timber structures Timber frame

but in the mainstream this rarely happens. Rate of growth is influenced by the geographical origin of the timber, but also by forestry practice, length of the felling cycle and local terroir. Softwood with narrow growth rings is stronger than softwood of the same species with wide apart rings, but, counter-intuitively, the opposite can be expected for structural grade temperate hardwoods, such as oak.

8. Creativity As original and exciting structures are developed, the input from the structural engineer is critical. With long spans, or unusual shapes and new engineered wood products, there is a great demand for ingenious solutions. Some projects might require a purpose-made connector, for example, and it is particularly satisfying if the connection is invisible, although there is still a place for the display of visible fixings so that the load paths and the building’s function are easily interpreted. As another example, while checking for adequacy for a 30-minute fire rating, the simple device of upsizing the sections will allow for charring and ensure the residual section is structurally adequate.

9. The golden triangle This is a term used for three aspects of any project that need scrutiny: cost, time and quality. Two of these can usually be achieved, but sometimes the third will suffer. It might be quick and cheap, but of low quality. It might be a sensible programme and specification, but at higher cost. To balance all three

is a challenge, and the structural engineer has a key role. Keeping abreast of new engineered products and methods of construction, combined with a bit of lateral thinking, can make a big contribution. Main contractors can help by encouraging teamwork and avoiding delays. The client can also help by being clear about what they want, decisive when necessary and patient. Good buildings need good clients.

10. Case study: St Edward’s School This project is an excellent example of engineer and designer collaboration: a new three-storey academic centre, dressed in stone, surrounded by the Victorian architecture of an independent school in Oxford. Designed Academic Centre West Elevation, St Edward’s School. by TSH Architects, with main Photo: Duncan McNicol contractor Gilbert-Ash, the top floor is the new reading room. The structure comprises a series of 19 identical portal frames and a diagrid roof plane with diagonal members. The roof pitch is steep (50°), to mirror the surrounding architecture, and the walls and roof are lined with veneered plywood panels. A distinctive feature is that the glulam columns and beams are all in oak as opposed to the more widely specified whitewood. Much attention was given to the lighting design, supplemented by a clerestory of roof lights. >>

One challenge was the requirement that no fixings should be visible from inside the building and another was the narrow section (120mm), limiting the size of connectors to maintain permissible edge distance. To achieve a moment connection at the column base was straightforward, using bonded rods, but connections between columns and beams, and at the apex, were another matter. A joint was devised using a solid billet of milled steel, with a tight 1mm tolerance, to act in shear, creating stiffness at the ‘knuckle’, likewise at the ridge. Consultant engineers at Andrew Waring Associates proved that a single M20 bolt on each side was adequate, provided that the threaded rod was secured with a 20mm-thick plate washer.

Another innovation was the use of tapered dovetail housings for connecting the primary roof members, instead of a steel connection plate, saving the cost of more than 250 connectors. The narrow section limited the housing depth, but this was deemed adequate, making use of the fact that these were in oak and not a softer spruce. n

Stacking up off-site timber construction financials

Dr Mila Duncheva analyses the effects of Covid-19 on economic sustainability.


peculation abounds about the negative impact of the pandemic on the construction industry, such as challenges created in the supply chain and managing labour on site. Others have seen the brighter side thanks to off-site construction, with suggestions that building in the factory is the only viable option for the continuous growth of the construction sector, as it provides a more socially distanced environment with fewer changes in the number of people and trades involved dayto-day than traditional on-site construction.

This is all well and good, but if the numbers don’t stack up, the social distancefriendly working conditions won’t be enough to convince off-site sceptics – and the opportunity to enhance environmental and social sustainability by building off-site with timber will be missed too. Construction output contracted by 40% at the start of the pandemic and looking at the economic sustainability of offsite construction is more pressing than ever. We need to bust the myth that off-site construction is not financially viable.

Off-site timber economic sustainability: Scotland The Increasing Offsite Housing Construction in Scotland project – funded by the Scottish Government More Homes Division, Scottish Enterprise and the Construction Scotland Innovation Centre – mapped the capacity and productivity of 15 off-site timber manufacturers in Scotland and also investigated the publicly available financial metrics of 31 off-site product manufacturers in Scotland. The project concluded that, in 2018, the off-site sector in Scotland had an estimated £275m turnover and 1,686 employees with projections to reach £317m turnover with 1,724 employees by 2023. Most interesting were the results from the business model analysis, which used the available financial records of nine of these businesses who had consistently submitted full financial accounts for four years. All of the nine businesses produced off-site timber products – the predominant material used in off-site manufacturing in Scotland. The businesses outperformed the average statistics for the construction industry regarding: • profit • debtor and creditor payments • liquidity. Among these, the profitability of construction businesses is often the main sticking point in conversations about the financial viability of off-site construction in the boom-and-bust property cycles. The mean performance of the businesses in the latest available financial year analysed, 2018, can be assessed using three key performance indicators: • Gross profit – the ratio of the difference between sales and the cost of goods sold to total revenue expressed as a percentage. • Profit margin – the ratio of profit (loss) before tax to total revenue expressed as a percentage. • Return on Capital Employed (ROCE) – the comparison of net operating profit (loss) to capital employed expressed as a percentage. >> Timber 2021 Industry Yearbook

The Scottish off-site manufacturers sample outperformed the available benchmark data for the UK-wide construction and manufacturing businesses in all three indicators. The results were quite close for the gross margin. Yet for the profit margin, which takes into account not only Profit analysis adapted from Duncheva, Calcagno and the difference Hairstans (2019). Credit: Mila Duncheva between sales and the cost of goods, but also subtractions for interests paid such as bank loans and leases before tax, the Scottish off-site manufacturers were nearly twice as profitable as the average UK construction businesses. Some may argue that these numbers are less important than ROCE, which measures the profits you earn relevant to investments. Even here, Scottish off-site manufacturers were nearly 7% ahead of the average UK manufacturing business.

Multi-material off-site economic sustainability: UK The positive financial performance picture does not stop at Hadrian’s Wall. A quick analysis of the publicly available financial records of 13 UK businesses working in off-site construction, who won or were commended in the Offsite Awards 2020, revealed their combined annual turnover for the financial year ending in 2019 was £6.9bn and they employed 25,586 people in total. The sample included business who worked with all three main material types: • precast concrete • timber • light gauge steel. This analysis does not hold the same scientific rigour as the one for Scotland, but it is useful to paint a picture of the UK off-site sector’s financial performance. The results build the case for the financial viability of off-site manufacturing in the UK – the UK sample outperformed both the Scottish www.trada.co.uk

off-site businesses and the available UK construction and manufacturing benchmarks by more than twice according to profit margins and ROCE indicators, and by more than 7% according to the gross margin indicator.

What next? The construction industry is facing unforeseen economic sustainability challenges alongside other UK industries, but was hit particularly hard by the pandemic, resulting in twice as big of a reduction in GDP contribution than the UK average. The economic sustainability of businesses depends on their ability to continue operations. Others have already made the case for the socially distanced working conditions more easily available in off-site manufacturing facilities compared to on-site construction. The financial profitability analysis of off-site construction businesses in Scotland and across the UK shows that off-site construction can provide more economically sustainable business models than the construction and manufacturing industry benchmarks. This should be included as a consideration by businesses in their post-Covid-19 recovery plans to enable sustainable growth. n

Mass Timber Office Forum Oliver Hartley-Booth outlines the topics discussed by this focus group to help increase the use of mass timber in the commercial office market.


n January 2020, as a member of the TRADA Advisory Committee, I was approached by several industry leading developers with an idea to set up a forum focusing on mass timber and hybrid construction, specifically relating to the commercial office market. Popularity and uptake of mass timber and hybrid structures has been rapidly increasing in the past five years for many reasons. More recently the urgency to address the climate change crisis and increased focus on improving the health and well-being of the end-user has propelled this form of office construction to the forefront of commercial developments across the UK. The embodied carbon credentials of timber have an incredibly important role in reaching the ambitious targets that the UK and many countries around the world have set to achieve net zero carbon by 2050 or before, to begin to tackle the effects of climate change.

Structure and aims The team at Gardiner & Theobald (G&T) set about structuring the forum’s sessions into the following categories:

The main purpose of the Mass Timber Office Forum is to bring together experts and stakeholders from across the industry to discuss and debate the barriers to using mass timber in office construction. Originally due to be held in person at G&T’s headquarters, the series had to pivot and reorganise digitally due to the impact of Covid-19 and the national lockdown implemented in March 2020. However, this challenge presented a fantastic opportunity to host these sessions as webinars that could be www.trada.co.uk

recorded and then distributed to a larger audience to share knowledge and experiences. TRADA, the Timber Trade Federation and the Structural Timber Association are part of the forum audience, and are actively collaborating to ensure the lessons from these sessions are disseminated across the wider industry. The forum is co-hosted by G&T’s Matt Holman (the Chair) and myself, and the monthly sessions focus on hot topics to help share knowledge and information that can be referred to when considering mass timber for commercial office projects. To date, eight successful webinars have taken place, discussing key topics such as insurance, fire, sustainability, capacity, best practice in construction and cost.

The insurance forum Voted by the audience to be the number one barrier to market for mass timber office buildings, the first session discussed: • the value of the mass timber industry1 • current barriers to market • the way forward with the insurance of mass timber offices both during and post-construction. The use of mass timber across the industry is increasing, generating a wider debate in the insurance industry on the assessment of timber buildings to evaluate the insurance premium requirements against the differing risks to concrete and steel structure frames. Some of these risks don’t fit easily into long-established construction classes and comparatively little statistical data exists to help insurers when underwriting mass timber buildings. Experts included: Andy Desmond of Marsh, Dominic Lion of Gallaghers, Caroline Hairsine and Oliver Wright from Aviva, Andy Penny and Robert Innes of Zurich, Nick Tilley from AXA, and David Lyle from Lockton. The panel discussed how these challenges also present opportunities for the sector, and how increased collaboration across the supply chain, data sharing and early initial engagement with the insurance industry could help mitigate these risks. >> Timber 2021 Industry Yearbook

The fire, testing and building control forum The second session discussed the issue of fire in mass timber2 in both pre- and post-construction, as well as the work currently being done by stakeholders on the behaviour of mass timber buildings in the event of fire. The panel of experts included: Sam Liptrott, Director at OFR Consultants; Judith Schulz, Director at Arup; Mark Pundsack, Assistant District Surveyor for City of London and Building Control; and Prof Jose Torero, Professor of Civil Engineering and Head of the Department of Civil, Environmental and Geomatic Engineering at University College London. The group spoke about the importance of design when using mass timber products and how a few small changes could help to mitigate the risk of fire during construction. The forum audience were asked which elements of the design would be affected by the inclusion of mass timber and, as shown in Figure 1, although many answers were given the overriding message from the panel was that all elements of a development can be affected by the inclusion of mass timber making the design phase of a mass timber development extremely important. The panel also responded to questions raised during the previous forum on insurance and how the industry can work together, sharing knowledge to mitigate risk and reduce insurance premiums for mass timber developments. www.trada.co.uk

The group agreed that there is much that can be learned from other countries; examples from the Netherlands and the US provide inspiration on how to incorporate greater use of mass timber within our developments. There was also an appreciation from the panel of differing approaches to risk and suggestions for how we could take the principles and processes adopted by these regions and apply them to our own UK standards and guidance.

The sustainability forum The third session discussed the role that mass timber commercial office buildings can and will play in contributing towards the global net zero and sustainability agenda,3 as well as improving the health and well-being of a building’s occupants. The panellists, including Simon Sturgis, Managing Partner at Targeting Zero, Anna Denell, Sustainability Director at Vasakronan and G&T’s Environment and Sustainability Director, Richard Francis, also discussed the potential impact mass timber can have on achieving net zero by 2050, with the audience being asked whether they thought the health benefits of mass timber will accelerate the transition to net zero – the overall majority voted ‘Yes’ (85%).

Representatives from GRAHAM, Kier, Lendlease, Mace and Mid Group shared their experiences and lessons learned from using mass timber on recent projects. The group all felt positive about working with mass timber and cited that preventing and dealing with water ingress is one of the key challenges, albeit they all agreed this risk can be mitigated in a variety of ways at the procurement stage. They also agreed that collaboration was important, not just within the UK but also when learning from international projects.

The cost and programme forum In the fifth session the panel of experts focused on what implications using mass timber for office construction may have on a project’s cost, programme and the procurement approach,5 from the design phase right through to construction.

Collaboration was highlighted to be vital for the success of a mass timber project and, following a live poll (as shown in Figure 2 ), the audience voted 95% in favour of collaborating with other firms and key stakeholders to create a bespoke testing programme for these materials.

Remaining sessions The series has examined the impact that using mass timber may have on the cost and programme of a project, as well as the capacity of the supply chain for mass timber and the considerations needed for the structure, MEP and acoustics. The programme will conclude with a final session on architecture and design in April and culminate in a White Paper documenting the key considerations and learnings from each discussion, due for release in spring 2021. n

About the author

Comprising five G&T experts, Matt Holman, Steve Bennett, Paul Robinson, Jess Pennell and myself, the panel discussed the various steps and considerations that need to be made when choosing mass timber solutions. Not only did the group consider pre-construction and the design phase of a project, but also the team that would need to be selected to deliver a mass timber project successfully and the stakeholders that would need to be consulted throughout the duration of a project.

Kelly Harrison discusses how engineered timber offers solutions to the challenges of adapting existing buildings, and highlights lessons learned. Glulam column baseplate on RC slab

ith climate targets and deadlines closing in, adapting and retrofitting buildings is a brilliant way of achieving low-impact developments. But how can this be achieved if the existing building does not have the required layout, enough net floor area or is generally an unknown?


The fact is, existing buildings often have built-in excess capacity. With thorough research to find the original drawings and investigations to expose and test structure on site, it is possible to adapt and extend to suit a new market, rather than demolish and start again.

Refurbishment brings challenges: • Strengthening existing foundations is difficult and costly. • Existing superstructure may not be laid out in an optimum arrangement. • The buildability in and around an existing building and site, especially when some areas are occupied, can create logistical and viability issues.

Engineered timber has solutions to many of these issues. Its high strength-to-weight ratio means that it has the capacity to support the required loads while adding much less weight to the existing structure and its foundations than other materials. Strengthening and work in the ground are therefore significantly reduced. Its off-site factory production, and minimal weight, are also ideal if you need the surrounding existing building to remain in use duringCLT construction, or if bolted steel there is any below-ground infrastructurethrough such as rail tunnels shoe plate, or services – the use of engineered timber can help reduce anchored to the programme time and minimise risk and disruption. concrete

Acoustic separation is a challenge with CLT; its lightweight nature means that it has little mass to stop noise transfer. This must be addressed early on, as the acoustic build-up can add to the floor thickness and therefore increase the floor-to-floor height of the building. In some situations it can also cancel out the weight saving gained by using CLT in the first place, and detrimentally increase the strengthening required to the existing structure below. Products and details are available that provide a relatively heavy finish over a raised floor, which can increase the performance. There are no building regulations for acoustic separation between office floors and so clients should understand what they are requesting and its impact on the carbon footprint of the building.

Waterproofing details, temporary for the build and proposed for the design, should be considered carefully. If the existing building is occupied at lower floor levels or in part, a temporary roof may be appropriate. A detailed water management plan should be provided by the main contractor to manage the water by all trades until the building is completely watertight. A temporary watershedding drainage solution must be in place during Think and about the reinforcement construction which ensures that water is routed away from you cannot see. areas that may be susceptible to ponding or other surface wetting so there is no water damage to the timber.

Timber structures Engineered timber

Expanding into the airspace: why engineered timber is a good fit Lee Murphy assesses the challenges and the overall benefits of using mass timber in roof top construction. he new Permitted Development Right (PDR), which came into effect on 1 August 2020, enables property owners and freeholders to extend upward into the airspace by two storeys without the need for planning permission. The value of extending into the airspace is increasingly being recognised by developers, and the sale, lease or transfer of ‘airspace rights’ is becoming big business.


This is an important trend, particularly for major cities where available land is limited and values tend to be high. The 2017 Greater London Authority’s London Strategic Housing Market Assessment identified a need for 66,000 new homes a year in London, but the reality is that this need is not being met. Airspace developments can help to meet the shortfall in new housing, also addressing issues of high-density living and the efficient reuse and adaption of existing structures.

Benefits and challenges Expanding into the airspace is a good way for building owners to maximise the return on their investment. However, there will be some issues for project teams to be aware of that are specific to airspace developments, including the questions of weight and how to interface with the existing structure.

As a mass timber and hybrid construction specialist we have recently delivered several cross-laminated timber (CLT) airspace schemes and there are generally logistical constraints around site access, material deliveries to site and working on the rooftop of a potentially occupied residential building. This is where CLT comes into its own; CLT is a lightweight material, highly accurate and efficient due to prefabrication, and its use ensures speed and ease of construction with zero waste. Operating on just-in-time principles, the number of deliveries with CLT is minimised, as is disturbance to neighbours and the pre-cut panels can be lifted on by crane, which is a major benefit due to the constrained nature of many rooftop sites.

Commercial extensions Commercial buildings provide an ideal environment for the addition of two or more storeys. In 2016 Lancelot Homes used CLT to create eight duplex apartments on the roof of a 1970s, threestorey brick built, mixed-use commercial and residential building in Kingston-upon-Thames. Originally purchased by King Street Group in the early days of the permitted development rules, the scheme was designed by Stephen Davy Peter Smith Architects to Level 4 of the Code for Sustainable Homes (now defunct). ‘From the outset the design intent was to develop generously sized residential units that would be compliant with the London Plan should the client wish to sell it on, for example to a housing association,’ says Architect, Stephen Davy. The original owners in fact sold the site to Lancelot Homes and the rooftop apartments were developed for private sale while maintaining the London Plan space standard. ‘Lancelot homes were keen to use CLT for the scheme and we were familiar with CLT and keen to use it, too. The building structure and layout could accommodate CLT and it helped resolved complex roof geometries at the rear of the scheme where a small neighbouring courtyard raised some right of light and sunlight issues. The fact that the panels are formed in highly efficient factory conditions and the elements cut to fit allowed us to get an envelope up quickly, including the complicated roof >> Timber 2021 Industry Yearbook

‘One thing we learned was that if we were to do a similar project we would partner up earlier on in the planning stages with a mass timber specialist like G-frame Structures. There is a lot of thought required and by partnering with a specialist early on you get greater cost certainty.’

pitches which were then overclad. This was far easier than installing a steel frame then having to adjust and work the geometries and fill the gaps between.’ ‘The great thing about this building was that, although only three storeys in height, it was a concrete frame, a pretty solid structure for that scale of building, which meant adding the two storeys on top wasn’t an issue. A commercial building is generally designed to take heavier loads and, by using a lightweight structural material such as CLT, the potential is there to add storeys. However, some more modern commercial buildings may have a substantial frame, but the nature of the build could make it trickier; for example, with a steel frame office building you would have to consider more carefully the detailing and isolation for sound transfer between units.’

Residential extensions The private residential sector is also seeing an increase in the number of airspace schemes, both single and multiple units. ‘There’s a huge opportunity for airspace developments in the private residential sector, as long as they’re done well,’ says Mark Stevens of HASA Architects. ‘The development needs to be responsive to the typology and context. I think we could develop airspace typologies, for example, with modularised systems or a choice of typologies that can work on Edwardian or Victorian terraces. This could certainly address the shortfall in housing, as well as giving people the option to grow instead of having to move.’ HASA has recently completed a 25m2 rooftop extension for a private client in south London. The home is an end-of-terrace house, part of an original boarding school that was converted in 2000 into six semi-detached houses. ‘The client wanted to achieve an en-suite master bedroom with roof terrace and to get the maximum amount of light possible to the property. They had a relatively limited budget and wanted something that would be quick to erect, so we took them through the path of looking at a CLT prefabricated structure that could sit on the existing building. We used CLT in its raw state with a light white wash.’ www.trada.co.uk

Harry Reid, Architect at Fletcher Crane Architects, comments: ‘The majority of new buildings are still using traditional construction, but the question is – is it a responsible piece of architecture in terms of materiality and climate? Architects need to have this at the forefront of their minds and persuade stakeholders and clients down this route, even if it ultimately costs them a bit more.’ Fletcher Crane Architects completed Water Gardens Pod in 2019, delivered after winning a competition held by the Church Commissioners to design a home for private rental at Paddington’s famous brutalist Water Gardens Estate. The innovative new home slots neatly between two existing buildings demonstrating the versatility of CLT, and its ability to overcome tough design and site requirements. The mono-pitched pod, which accommodates three inward-facing bedrooms and three bathrooms, features exposed CLT internally and links to the main building by a glass entranceway.

Summary It is clear that airspace extensions offer a new avenue of opportunity for innovative construction. Lightweight engineered timber solutions are ideal for the versatile and flexible design required to make the most of these sites. Its environmental benefits can only add to its suitability as a construction method for achieving airspace extension. n

What they say about us... Paul and his team were fantastic. they provided us with a great garden room and decked area. I would have welcome him and his team back to work anytime, and strongly recommend TimbaBuild. Extremely reliable, helpful and friendly, did a fantastic job installing a lovely decked area and also some gardening works. We are delighted with the result and would not hesitate to recommend to anybody, thanks. Absolutely brilliant. As I was not able to be there when the work was being carried out, I had to have complete faith that they would carry out what I wanted and to complete on time. They surpassed all expectations and have since been back to do other work. I would highly recommend. They arrived to do exactly as they said they would, very professional and skillful. We found them friendly, reliable, and wouldn’t hesitate to recommend them to anyone, we are delighted with the completed job.

Timber structures Engineered timber

Moisture management Nick Clifford and Lewis Taylor reflect on lessons learned through consultancy work on the importance of accounting for timber’s hygroscopic properties when building with engineered timber.


odular timber building products such as crosslaminated timber (CLT), structural insulated panels (SIPs) and closed panel timber frame cassettes offer significant time savings during construction. Compared to steel, masonry or concrete buildings, the primary structure can be erected quickly using prefabricated or modular timber systems. However, these non-timber forms of construction are largely unaffected when exposed to the prevailing weather unlike prefabricated timber building systems that can absorb and retain rainwater due to timber’s hygroscopic properties. Once the building is complete, timber components will dry out due to these same hygroscopic properties, but if they are enclosed at a very high moisture content, drying can take a sufficiently long period of time that fungal decay becomes a risk. A greater consideration of moisture management is therefore needed for prefabricated timber building systems, starting at the design and project scheduling phase, following through to the construction site. Through BM TRADA’s consultancy work, we have been involved in several projects where ineffective planning and moisture management has led to time-consuming and expensive drying works during construction and defects in newly completed buildings. These types of defects can undermine confidence in timber building systems.

Moisture uptake is much greater at panel perimeters than across the surface. Moisture assessments should focus on the higher risk zones.

Considerations Trapped water within pre-insulated closed panel walls and standing water on flat roofs are particularly concerning; avoiding these issues should be considered in the design, construction and phasing of timber buildings. Small buildings with short build programmes are typically low risk, but large multi-storey residential buildings and extensive commercial and education buildings are at a higher risk due to the extended nature of the build programme. Despite closed panel timber frame walls being factory wrapped with breather membrane and vapour control membranes, there is a risk of water penetration into the panel around window openings or at the top. Traditional open-panel timber frame will also be exposed to wetting during construction, but the open nature of panels allows water to quickly drain away, drying the timbers when conditions allow. However, factory-fitted insulation and vapour control layers to closed panel kits can hold or trap moisture within the panels resulting in a greater risk of elevated timber moisture content.

Reducing risks

Standing water on CLT during construction should be minimised whenever possible.


The risks of trapping water within wall panels can be reduced by ensuring that windows and roof coverings are installed as soon as is practicably possible once the timber structure has been erected. Robust lapping of membranes around window openings and at the top of panels can also help to reduce risks along with consideration of vertical phasing and timely engagement of follow-on trades. >> Timber 2021 Industry Yearbook

Timber structures Engineered timber

Flat roofs can be subject to standing water during construction that can lead to excess water uptake, particularly at the edges of panels. If designing a timber building with a flat roof, it is beneficial to include a fall within the timber elements to encourage drainage during construction, rather than creating falls with insulation. Although creating falls with insulation is reasonable, the difficulty lies in the time between installing horizontal panels and installing insulation and waterproofing. Depending on the size of the building and handover procedure, this period can extend for weeks and in some cases months, resulting in prolonged exposure to standing water. Improved project scheduling can reduce this time, but it may be difficult to achieve a scenario where flat roofs are insulated and waterproofed in rapid succession after panels are installed and it is therefore important to ensure on-site moisture management. Most timber panel manufacturers and suppliers increasingly recognise the need to highlight the importance of moisture management to architects, project managers and contractors.

Best practice Ideally, timber panels should always be protected from prolonged exposure to the prevailing weather and kept free of standing water, but given the maritime climate in the UK, complete avoidance of wetting during construction is not realistic and it is likely that moisture management planning will be needed. For example, correct lapping of membranes to walls and regular removal of standing water from flat roofs.

Moisture content readings Water trapped within closed panel timber walls is often hidden by vapour control layers and other factory-applied finishes and is not easily detectable without taking moisture content readings within the panel. Standing water on flat roofs will eventually dry from the wind and sun but it would be a mistake to assume that roof panels are then dry; using incorrect equipment can lead to the mistaken conclusion that no residual moisture remains. Plywood and oriented strand board (OSB) roof decks and sheathing boards are relatively thin and can be checked for moisture using the 12mm to 15mm prongs in-built to most electrical-resistance moisture meters; fully embedding the prongs will measure moisture through much of the panel thickness. However, this method is not suitable for thicker timbers such as sole plates or solid wood panels such as CLT, where residual moisture can be much deeper. Deep readings are needed to ensure that high moisture levels are not missed; proprietary hammer probes and insulated deep probes are available with measurement depths ranging from 35mm for hammer probes to insulated deep probes up to 250mm long. www.trada.co.uk

The base of vertical CLT panels can be vulnerable to moisture uptake during construction.

Metallised membranes such as reflective vapour control layers can short out the electrical resistance moisture meter pins giving artificially high readings and so insulated deep probes are normally required to ensure measurements are only taken from the timber behind. BM TRADA consultants have seen several cases where moisture content readings taken using insufficient probe lengths and from the wrong areas have incorrectly been used as evidence that panels are dry throughout. To gather meaningful data, moisture must be measured not only with the right equipment, but also where the risk of wetting is highest. Although moisture uptake through panel faces does occur, for CLT, plywood and OSB, moisture uptake is greatest at panel edges, so the 300mm or so at horizontal panel perimeters should always be a focus in moisture checks. Sole plates and the lower 300mm of vertical or pitched panels are also higher risk zones.

Variations Inevitably there will be times when prefabricated timber panels are exposed to prolonged wetting during construction. The effect of wetting on panel performance is dependent on panel type and grade, as well as the panel orientation and the period of exposure. BS EN 636-2 and BS EN 636-3 grade plywood should be able to withstand exposure to moisture during the construction phase and, once dry, should perform as normal. >> Timber 2021 Industry Yearbook

Timber structures Engineered timber

OSB3, a common grade for SIPS panels and closed panel cassettes, has a reasonable resistance to construction moisture and, if swelling in thickness has been avoided (for example after short term exposure), OSB3 should perform as normal once dry. However, if swelling in thickness has occurred, the panel manufacturer should be consulted and/or testing Moisture can be held deep within CLT panels so surface readings are insufficient and the correct undertaken as equipment is required. panel strength may be reduced. This may be of particular concern for SIPs where structural loads are taken solely by the OSB panels. With good ventilation, relatively thin plywood, OSB or chipboard panels typically dry quickly, unless they are in contact with wet mineral wool insulation or where drying is restricted by vapour control membranes. Experience shows that CLT can take considerably longer to dry fully after exposure to construction moisture, and this drying rate may not be fast enough to avoid a decay risk by woodrotting fungi. This highlights the importance of using the right equipment to monitor moisture in CLT, which may be held deep within panels.

are often needed to dry deeply embedded moisture in thicker timber components. Such prolonged drying periods delay project scheduling, which reinforces the importance of moisture management at all stages of design, scheduling and construction.

Conclusion Prefabricated timber building systems, such as closed panel timber frame, SIPs and CLT, can offer considerable advantages in speed of build, cost, environmental impact, in-use energy performance and aesthetics when compared to other forms of construction. However, as higher levels of factory prefabrication occur, moisture management and care of panels during construction becomes of greater importance in ensuring contractors, clients and building users can realise these benefits. BM TRADA encourages all parties involved with the design and construction of prefabricated timber buildings systems to take time to consider moisture management not just as an afterthought if problems arise, but as an important and beneficial exercise. If the industry is to embrace more advanced methods of off-site construction (including non-timber based off-site systems), thinking about moisture management should become a normal part of the building process. n

Drying Where high moisture levels are identified, active in-situ drying is often the only option and this must be carried out before enclosing the panels with insulation and vapour control membranes which severely restrict drying pathways. Where factory-insulated closed panels become wet during construction, it may be necessary to remove internal vapour control layers and wet insulation to aid the drying process. Passive ventilation with ambient air is of some benefit in warm, dry conditions, but is of little benefit in colder months – colder temperatures reduce the rate of water evaporation from the surface of the panels. Active ventilation with warm air is usually required, and drying periods of many weeks or even months www.trada.co.uk

Materials Durability

Service life performance of wood in construction Ed Suttie reveals how a new project is calculating the durability performance of wood.


hen we buy a house, it is rare that we scrutinise durability aspects of performance in relation to how long the whole, or components of the whole, will last or function. We understand a need for upkeep and maintenance, and we may make decisions based on perceptions or experience and avoid surprises by engaging a professional surveyor or take comfort from new home warranties. In the construction industry, we need to understand durability to design a house, which raises the question ‘How long does a house last?’

What is a forever home? Victorian houses, among others, have transitioned into our national conscience as an important part of our urban landscape, many afforded conservation status, and as

such they might last ‘forever’ as we invest significantly in maintaining and upgrading them. However, many house types, and perhaps many new-builds, may never be valued as conservation-worthy, through loss of functionality or undesirableness, and be lost sooner, such as a poorly designed post-war housing development that is demolished after only 40 years in service. More empirically, whole building environmental assessment methodologies, for example BREEAM1 and the former Green Guide to Specification,2 set a lifetime for a home that reflected the study period for the life-cycle assessment (LCA). This lifetime was set as 60 years, a little more than two typical mortgage cycles. This enabled comparison of environmental impact for components that may be used for the same function but which are made of different materials, and with different maintenance and replacement intervals.

Orientation on the performance of wood, understanding service life of wood in buildings. Photo: Ed Suttie


The service life of the components (windows, doors, floor cassettes etc) therefore became the focus of interest and significantly affected environmental assessments such as LCA, and latterly environmental product declaration (EPD). A component that needs to be replaced twice in the 60-year study period would have a much greater lifetime environmental impact than a component that only had to be replaced once, or even not at all, during the 60 years. >> Timber 2021 Industry Yearbook

The need for service life data Building Information Modelling (BIM) maintains information in a suitable format so that better decisions can be made about planning, design, detailing, occupancy and end of life. The life cycle data management in BIM needs service life data and functionality data for components and assemblies, as well as information on changes to the asset during its lifetime. BIM therefore requires durability service life data and will, in future, determine decision-making regarding component and structure selection based on performance. Service life of components is determined from models of degradation of the component in its exposure and use conditions, often combined into a factor method such as described in ISO 15686.

Wood in construction We have a cultural legacy of wood in construction that reminds us of the enduring possibilities for wood, if knowledge is applied – including species and material qualities, design details and construction skills, knowledge of local conditions, and climatic and other challenges. How long do wood products last? Well, of course, it depends – a block of wood on my desk will last forever if the building around my desk and internal conditions remain the same as they are now. However, durability service life data can be fragmented and complex to analyse. The performance of a wood product in service is the combination of the material resistance (durability, coatings) and the exposure (climate, design, environment). If the exposure dose is less than the material resistance, the product endures until the exposure dose exceeds the material resistance (for example, as it weathers) and onset of decay or significant surface colour change occurs (the limit state). www.trada.co.uk

Performance-based specification Service life planning and performance classification are core issues in construction, underpinning product specification and use. The absence of easily accessible durability and performance-based specifications for wood currently limits opportunity. Concrete, steel and polymeric sectors deliver software to architects and other students of construction, enabling performance-based specification and consistent teaching of design best practice. This does not happen comprehensively in Europe for wood, although specific initiatives do exist, for example: • TRADA’s National Structural Timber Specification (NSTS)3 • UK Structural Timber Association guidance4 • German Carpenter Association’s Guideline on Building Facades, Terrace decking and Balconies.5 But this specification gap, and the fact that technical specifications for performance are increasingly required for BIM and LCA, has driven the development of ForestValue6 project CLICKdesign. The project is developing a performance-based specification protocol for wood in construction and is providing a software tool for service life performance specification for planners and architects.

Service life The established specification of wood durability is not performance based. Service life is referred to as unquantified and in an ambiguous way, using terms such as ‘reasonable working life’ or ‘satisfactory performance’. Timber engineers using Eurocode 57 find that this ineffectual language is of little value. For performance modelling of wood products, biological agents (mould, decay fungi, termites and other insects) need to be considered. First attempts were prepared using various models that had been derived from previous European research projects. Good progress has been made during more recent years in service life planning and performance prediction of wood-based components and structures, but, as repeatedly became evident, the complexity of performance is still not captured in these processes and it remains ‘on the shelf’ rather than in use. The foundation of previous work has now been reviewed and this has enabled a running start to the CLICKdesign >> Timber 2021 Industry Yearbook

Materials Durability

Conclusion Wood is a versatile construction material, which can make a highly significant contribution in tackling the climate emergency – through forest growth and by locking carbon into buildings. This may be achieved by specifying timber products in place of other construction materials that have greater impact on the environment. However, of equal importance is that the wood product must perform its function for a satisfactory period (the service life), ideally the lifespan of the building. Therefore, as we take custodianship of this incredible carbon store, it would make folly of nature’s good work and our endeavours if it were inappropriately specified for the exposure challenge it will face over its lifespan, and as a result failed prematurely with the resulting economic and social consequences.

project, which has generated data on significant missing features related to performance, such as splash water, cracks, vegetation and topography. In addition, project CLICKdesign includes a focus on robust time forecasting of aesthetic changes on wood surfaces – a vital component of functionality for exterior wood cladding and decking.

As data is central to decision-making, the information about the service life for wood products is a foremost question. To fulfil the maximum potential of the contribution of timber in construction to the United Nations Sustainable Development Goal 13 (Climate Action), wood products must deliver long-term carbon storage through performance-based specification. n

CLICKdesign project The tool is based on a numerical model that enables the user to zoom in on the location of their building or structure in Europe and automatically upload average climatic data. This provides default moisture content data for a Norway spruce board and a service life figure at that location. By implementing selections for design details (end grain, moisture traps, joints, shelter from overhangs), topography and shading, further impacts on the moisture content and service life are revealed. If the outcome is not acceptable, different materials of different material resistance can be selected. This helps educate users as they can directly see the impact of their decisions on the moisture content and service life. The aesthetics model that combines with this unfolds the surface of the building to create a UV surface map and, combined with material data, provides a simulation of surface wood appearance for predicted rain cycles. Architects can see how their timber clad design will change in appearance with time. The next step is to integrate a termite and insect measure into the durability and aesthetic functionality, to make the tool pan-European. The tool then be made more widely available in 2021 for piloting with groups of specifiers and architects. www.trada.co.uk

“UK forests already have a number of other tree species that are currently under-managed for the production of wood, but which could potentially be brought into the supply chain in the near future.”


he UK’s commercial forestry is based largely on one species, Sitka spruce, which provides wood fibre for use in a wide range of uses, including construction, pallets and packing, fencing, panel products and paper. There are other important economic species, such as Norway spruce, Scots pine, larches, and Douglas fir, but a little more than half of the total volume is Sitka spruce because this species grows and processes so well.

With more than 15 years of research at Edinburgh Napier University, the properties of these timbers are now well known, but this does not necessarily provide certainty for the future. Just these few species, together with two more pines (Corsican and lodgepole), account for as much as 95% of the total home-grown softwood available for harvest, which raises concerns about the resilience of the forest, and the industries and livelihoods that depend on them, against the effects of climate change, pests and diseases.

Disease and diversity There is now a different, and more personal, perspective on the need to keep a disease outbreak under control, but there is also no shortage of high-profile examples for trees too, such as ash dieback and Phytophthora ramorum, which are causing enormous damage in the UK, and Xylella fastidiosa, pinewood nematode and spruce bark beetles in Europe. One way to protect forests, which also brings many other benefits for modern multipurpose forestry, is to plant a much wider range of tree species – but how can we prepare our wood products industries for a more diverse raw material? UK forests already have a number of other tree species that are currently under-managed for the production of wood, but which could potentially be brought into the supply chain in the near future, though the real challenge is preparing for what is being planted now. There is information in books and databases about these other species when grown in other countries, but data is sparse about what the properties would be like when grown in the UK (except that there is a good chance that they will be different), or how suitable they would be for processing in mills that have optimised their operation for the relatively small list of current species. >> www.trada.co.uk

Research project A study by the Strategic Integrated Research into Timber (SIRT) project took a preliminary look at certain potential alternative species, to gauge what properties could be expected from growth in UK forests, and how they might complement the existing commercial species for the wood processing industries. Initially, seven species with promising forestry potential were selected through consultation with the Forestry Commission (as it was then known), and members of the SIRT project management board and sponsors representing the forestry industries. The study covered Pacific silver fir (Abies amabilis), European silver fir (Abies alba), grand fir (Abies grandis), Japanese red cedar (Cryptomeria japonica), Serbian spruce (Picea omorika), sycamore (Acer pseudoplatanus) and silver birch (Betula pendula). A previous study, with additional funding from the Scottish Forestry Trust, covered Norway spruce (Picea abies), noble fir (Abies procera), western red cedar (Thuja plicata) and western hemlock (Tsuga heterophylla). A Forest Research project also enabled some testing of Nordmann fir (Abies nordmanniana). Some of these species had, so far, only been grown in small amounts, but thanks to the work of the Forestry Commission there were some reasonably representative stands in forest gardens and other experimental plots. Nevertheless, it requires a large amount of testing across several sites to properly characterise a timber species for commercial production from a particular geographical origin, so the data that follows can

only be an indication of potential, pending more comprehensive study. This was especially true, even for the very common species birch, because the available trees, not being managed for timber, were too small to produce many timbers of the 100mm x 50mm size we used for evaluating strength. The European grading system for structural timber is based on density, strength and stiffness (usually in bending), and it is usually one of these that will limit the achievable grades. For example, Sitka grown in the UK tends to be limited by stiffness when grading to standard BS EN 3381 strength classes, but other species can be limited by strength (such as UK-grown Douglas fir) or by density. This preliminary testing is enough to indicate the most likely limiting property, but the strength class estimates are more tentative. >>

Outcomes Softwoods Results of this study indicate that UK-grown Japanese red cedar, which is one of the most economically important species in Japan (where it is known as sugi), would struggle even to make C14, due to low stiffness and a remarkably low mean density of just 310 kg/m3.2 This does not mean that it does not have its uses, where its low weight could come in handy for use as studs in partition walls, or even super-lightweight crosslaminated timber. It is an attractive wood, but also rather soft.

If grown in the UK, four of the North American species – grand fir, western red cedar, noble fir and Nordmann fir – also look like they might not be able to achieve the usual UK market strength class, C16, with high grading yields, the first two due to low stiffness and the second two due to low strength. This, however, might well be due to the limited testing, particularly for grand fir and Nordmann fir. The other properties measured for grand fir showed more promise, with strength suitable for C16 and density suitable for C18, and similarly with Nordman fir, where stiffness was equivalent to C18 and density C30.

The other two North American species look like they would be able to achieve viable C16 yield for grading, if grown in the UK. Pacific silver fir is limited by its density and western hemlock by its stiffness. However, western hemlock, being rather similar to Sitka but with higher density, is a good candidate for blending in with existing British spruce supplies. Pacific silver fir, with strength and stiffness both looking to be around the C18 mark, might have potential for lightweight construction, even compared to Sitka spruce – which was historically favoured for building aircraft. Three UK-grown European species of conifer were included – of these, European silver fir looks limited to C16 by stiffness, but strength and density again far exceeded this grade (C20 and C27 respectively). Serbian spruce looks to be limited to C16 by strength, but had good stiffness (C18) and density (C40). Norway spruce is already known to be similar to Sitka, which grades very well to C16, perhaps with slightly better stiffness and strength. Many of these conifer species look like they could have potential to be blended in to the existing C16 ‘British spruce’ market, ideally by mixed processing, subject to adequate grading approaches. This is encouraging, as relatively small amounts of these species could start entering the mainstream markets with little disruption.

Hardwoods Two hardwood species, sycamore and birch, were looked at to see if they could be the equivalent of and be graded along with the conifers. Both species were found to have good properties; with sycamore, stiffness is the limiting factor and would fit the ‘softwood’ grade of C18. For birch, both the stiffness and strength are limiting factors, but fit the >> Timber 2021 Industry Yearbook

high grade C40. However, it proved difficult to get enough birch of the dimensions required, which not only meant that only limited testing could be carried out but also that it may be difficult to find enough suitable material for processing. Density for both these species is, unsurprisingly, much higher than the softwood grades require, but it is also not enough to grade well into the hardwood D-classes where it would become the limiting property, reducing the declarable design strength and stiffness.

Industry survey At the same time as this research, a survey was carried out asking for the thoughts, opinions and experience of sawmillers with these alternative species. The results showed that, while there is little or no experience of using some of these species, such as Japanese cedar, Pacific silver fir and Serbian spruce, this did not preclude everyone from saying that they would not be open to using them if they became available in the future.

There was some experience of the other conifer species, European silver fir and grand fir, with the latter being the least popular due to the presence of large knots and cracks, for example, which weaken the wood and create processing problems. Birch and sycamore were also known, with both species receiving a favourable opinion.

Thoughts for the future The information gained from this research into the mechanical properties of alternative timber species, together with information from the concurrent survey gathering the thoughts and experiences of professionals using these species and working within the industry, will help to inform future research. This research will feedback to industry to help make informed decisions for new planting and preparing the UK’s timber industry for the future. n

“This installation creates an accessible long-term research and display site in an interesting location where the cladding and joinery can be monitored over many years.”


n 2015 a prototype of thermally modified British hardwood cladding was installed at the Sylva Foundation Wood Centre in Oxfordshire, as part of a feasibility project by Grown in Britain. The Sylva Foundation is an environmental charity, providing silvicultural training and workplaces for woodworking enterprises.

Five years later and, after much testing and refinement to the product, a new batch is being installed by Vastern Timber under the brand name Brimstone. This cladding and joinery at the Sylva Wood Centre is the latest addition to what has become a long-term test site for this innovative material.

The project The aim of promoting under-utilised British timber aligns with Sylva’s goal of ‘helping trees and people grow together’. To create the latest test site at the Sylva Wood Centre, Vastern Timber supplied over 100 square metres of Brimstone cladding in three different species. Windows and a door were produced by George Barnsdale, using thermally modified ash. The front elevation, which faces west, has been designed to look relatively consistent, although it includes three species, three different profiles and three different fixing methods. The three species used are ash, sycamore and poplar, all of which have been thermally modified for external use. This installation of the cladding was the final stage of a large redevelopment project of the old grain store at the Sylva Wood Centre, providing new workspaces for woodworking enterprises and skills training. The remainder of the building was clad in British larch feather-edge, chosen because of its value for money and provenance. Brimstone cladding has been installed on hundreds of commercial and residential buildings, but it is often difficult to gain access regularly and for a long period of time. The installation at the Sylva Wood Centre allows continuous access to view the product and monitor changes. It is also rarely the case that one installation will include different cladding types alongside each other for comparison purposes. All wood looks great on day one, but it is far more relevant to know how the products will perform over time.

be monitored over many years. Brimstone has been tested to destruction in the lab but there is no better evidence than having the product in situ on a building for the long term. The Sylva Wood Centre development adds to the wealth of data covering durability, stability and consistency. Thermal modification can be used to transform under-utilised, locally grown species such as ash, poplar and sycamore into a durable, stable cladding suitable for a wide range of projects. The process uses nothing but extreme heat under controlled conditions to alter the cell structure of the original wood. The effect of the transformation is to make the wood more durable, stable and consistent. Although many wood species respond well to thermal modification, white hardwoods work particularly well. It is also a happy coincidence that these same white hardwoods are currently not in vogue and are consequently hard to sell in their raw form.

Five years of testing and development The first thermally modified British ash and sycamore were installed at the Sylva Centre in 2015 as part of a project with Grown in Britain, the organisation dedicated to supporting the use of British timber. The original batches have weathered nicely and show no signs of decay or distortion. Since the first material was installed, so much has been learnt about the material; how it performs and the best ways to install it. Although thermal modification is now a well-established process, investment in testing has helped to determine physical and performance metrics specifically for these products rather than relying on generic data. The species used have achieved Class 1 Durability for out-of-ground use in lab-based testing and mechanical tests have demonstrated a minimum of 50% improvement in dimensional stability.

Environmental Product Declaration To discover the environmental impact of thermal modification, a detailed life-cycle analysis of Brimstone was commissioned.

Environmental Product Declaration. Source: Sylva Foundation

The Environmental Product Declaration (EPD) was an extensive process, modelling the greenhouse gas removals and emissions in the life cycle of Brimstone, from the growth of the sapling to the eventual disposal of the product at the end of its useful life. This rigorous analysis of Brimstone enables like-for-like comparison with similar products, but the key benefit of the process was gaining a better understanding of the impact at each stage of production and the identification of potential impact reductions in the future. >>

Changes to the tests and requirements for fire and cladding

Mostafa Jafarian explains the regulatory developments and how these affect timber cladding.


lthough timber is historically one of the most commonly used materials for construction, the current climate emergency, and as a result the focus on sustainability and the reduction of carbon dioxide emissions, has prompted an increase in the specification of timber for construction projects.1-3 Advances in timber technology have also enabled designers to use hybrid timber solutions not only for low-rise construction but also for medium-to-high-rise construction (such as the 58m-tall Brock Commons Tallwood House in Vancouver, Canada,4 the 49m-tall The Tree in Bergen, Norway, the 33m-tall Dalston Works in London, UK and several others). Despite their advantages, timber structures are vulnerable when exposed to fire if not adequately protected.5 Fire safety of timber construction and the risks in terms of fire resistance and reaction to fire are specified in fire safety regulations.6, 7

Regulatory changes Following the tragic fire at Grenfell Tower, several standards have been subject to reviews and redevelopment, which has had an impact on the timber industry. In England and Wales this includes an amendment to Building Regulation 7 – Materials and Workmanship, the review of the Approved Document B (AD B),6 BS 84148 and development of BS 9414.9 The review of AD B led to amendments and clarifications. The main part subject to revision was part B4 of AD B dealing with external fire spread and the inclusion of the amendment text from Regulation 7. As a part of those changes, Regulation 7(4) defines so called ‘relevant buildings’, which means a building with a storey height of more than 18m* above ground level that contains one or more dwellings, an institution, or a room for residential purposes**. For this type of construction the external walls or specified attachments must be made from materials

Figure 1: Provision of the materials for external wall systems. Source: Building Regulations, ‘Approved Document B: Volume 2 – Buildings Other than Dwelling Houses’, National Building Specification, MHCLG, 2019

with a reaction-to-fire classification of A2-s1, d0 or better (when classified to EN 13501-110)***. For non-relevant buildings such as hostels, hotels or boarding houses with a storey height over 18m or other buildings with a height under 18m, the external wall can still be constructed with materials that do not achieve class A2-s1, d0 or better, provided that they comply with the recommendations given in paragraphs 12.3 to 12.9 of AD B (which offers guidance for external surfaces, materials and products, cavities and cavity barriers). The provision of the acceptable materials is given in paragraph 12.5 and table 12.1 (see Figure 1). The alternative route, as shown in paragraph 12.3 b, is to meet the performance criteria given in BRE report BR 135 for external walls using full-scale test data from BS 8414-1 or BS 8414-2.11 >>

* This height does not include roof-top plant areas or any storey consisting exclusively of plant rooms. The height is also under review and may be lowered further. ** This article discusses the changes applicable in England and Wales; similar regulations and guidance are published in Scotland with the limit set at 11m. Northern Ireland is likely to follow England and Wales in future. *** Some exemptions exist for component parts that are documented in Regulation 7(3).

How is timber cladding affected? The new recommendations mean that timber cladding, if treated to have an improved flammability performance, can achieve Class B at present but not A1 or A2, and must be tested to BS 8414-1 or BS 8414-2 (if used for construction above 18m for non-relevant buildings); see Figure 2. BS 8414-1 or BS 8414-2 are a series of well-known, largescales tests developed in the UK to determine the performance of non-loadbearing cladding systems under fire conditions. These tests are among the most stringent fire tests, duplicating a post-flashover fire scenario in a room with a total heat output of 4500MJ over 30 minutes at a peak rate of 3±0.5 MW. These standards have been reviewed and the latest versions are currently being applied. Although not subject to fundamental changes, there were some additional points. These include: • fixing the height of the rig (where previously only a minimum was stipulated) • an additional measurement level closer to the top of the rig (that can gather further information and can be used for more detailed classification of the cladding) • specification of the block work required for BS 8414-1 test.

Figure 2: Typical BS 8414-1 and BS 8414-2 arrangement. Photo: Warringtonfire Al-Futtaim


Aside from those points that directly affect technical aspects of the test, the latest version of the standards requires labs to provide more detailed information about the: • observations during and after the fire test • i nstallation and installers of the cladding system. Those points are particularly important because the performance of a cladding system is significantly affected by the detailing and installation of the key elements of the system.12

The new standard While the new regulations do limit the use of timber for construction above 18m, if the recommendations of the fire safety codes are followed (for example treatment of timber to achieve Euroclass B-s3,d0) and if the timber is appropriately and robustly detailed for construction, it could be tested to the relevant part of BS 8414 to demonstrate compliance. However, even within a single structure the detailing and cladding systems could vary. Therefore, as part of the review of the standards, the Government commissioned the development of a new standard BS 9414. BS 9414 was developed with the remit of having harmonised rules for extending the scope of application of cladding systems tested to the BS 8414 test series. It would also ensure that a new system could not record temperatures higher than the tested system. The new test regime will allow for previously tested products to remain valid, while extending the scope of the test to allow testing of newer products with more applications. This approach not only accommodates the need for the practical aspect of the test, but also makes sure that the change in detailing would not have an adverse impact on the overall performance of the system. >> Timber 2021 Industry Yearbook

Conclusion Although the changing regulatory environment has had an impact on the use of timber cladding systems, the new regulations still allow for these to be used where the detailing is robust and fire test evidence is provided. The regulations will ensure the fire safety of the end-use product before they are used as a part of a construction. n

“The substructure (posts, beams and joists) is equally as important as it forms the ‘system’ that supports the whole deck construction.”


he popularity of decking soared last year when circumstances forced people to spend more time at home and outdoor living became increasingly important. The Sunday Times confirmed that ‘Britain has fallen back in love with decking’.1 Readers were told: ‘If you choose timber, look for boards with the DeckMark symbol from the Timber Decking and Cladding Association.’ The article also recommended the Timber Decking and Cladding Association (TDCA) database for finding suitable installers – it is a mandatory condition of TDCA membership that installers are accredited to DeckMark standards, ensuring they are of high calibre and experienced in their craft.

The article focused on wood polymer composite (WPC) deck boards. Whatever material you choose for your decking, it is important to ensure quality verified products are used throughout and manufacturers’ guidelines are adhered to. A decking project consists of several components – going from the ground up; posts support the beams, beams support the joists and joists support the deck boards. Every part of this structure is reliant on the other, but all too often the focus of attention is predominantly on the deck board as it is the most visible part of the deck. The substructure (posts, beams and joists) is equally as important as it forms the ‘system’ that supports the whole deck construction. Whatever deck board you choose, in most cases the substructure will be made from preservative pressure-treated timber. The question is, will it be fit for purpose by being treated to the correct specification according to BS 8417 (the standard for wood preservatives in the UK)? 2

Deck joist specifications: prepare for change It is the role of the TDCA to provide relevant information to ensure decks are installed correctly, to give a long service life. This includes promoting sources of quality materials and services that carry independent accreditation. The TDCA has had to prepare the industry for a change in standards with regards to specification for decks. Going forward, all decking substructure components – not just posts, will be regarded as Use Class 4 application (outdoor, in ground contact) where previously they were Use Class 3 (outdoor, above the ground). The TDCA supports this >> www.trada.co.uk

positive move as it ensures timber used on or very close to the ground (as a lot of decks are set), will be treated to a higher standard. It brings us into line with Sweden, Finland, France and North America, where decks are regarded as safety critical end-use applications. The specification for deck joists will change when BS 8417 is next updated, but the TDCA is urging its members to be prepared and make necessary adjustments now as the changes provide a more robust approach.

The rationale is to create more order and transparency to the market. The scheme will actively endorse good-quality composite deck boards allowing endusers to review product credentials prior to purchase. The funds generated from membership of the scheme will be used to develop further resources to help promote goodquality decking and cladding products and installation practices. n

being reported to the TDCA, it became apparent that not all products are fit for purpose. This resulted in the TDCA working with the industry to develop a Product Approval Scheme (PAS) for wood-fibre based, wood polymer deck boards. A scheme document, based on current European standards, sets out what is needed to achieve accreditation. It features nine testing requirements that sets pass and fail criteria. The requirements include physical and mechanical properties, biological and physical durability, fire performance and slip resistance. The scheme also requires that clear, unambiguous information is given to the buyer in terms of guarantees, recycled content and any infrastructure in place to facilitate recycling. www.trada.co.uk

The Timber Decking and Cladding Association is a not-for-profit, technical and advisory body that exists to help professionals and consumers make the most of wood. It operates DeckMark, a quality scheme for products and for design and build contractors, and has a mission to develop the awareness of and demand for quality timber decks, associated landscape structures and external timber cladding – hand in hand with the best practice workmanship required to produce such projects. Raising awareness about the consequences of cutting corners and educating buyers about the properties of quality decking materials, design and aftercare are core activities.

Protection Preservation

How do you specify preservative-treated wood? Gordon Ewbank emphasises the importance of accuracy in achieving the desired service life for timber.


ember feedback from the Timber Trade Federation (TTF) and Wood Protection Association (WPA) suggests that meaningless generic expressions such as ‘pressure-treated’ and ‘green-treated’ are unfortunately still common. The inaccurate or vague description of preservative-treated wood products inevitably increases the chance of failure in service and subsequent customer complaints, particularly for outdoor applications. This inaccuracy risks damaging the reputation of timber as a reliable and versatile building material, undermining the opportunities to build confidence and grow the demand for treated wood. Additionally, consumer and contract law require that any product offered for sale must be fit for its intended use and a wood product impregnated with preservative is no exception.

Accurate specification and description The WPA and TTF work in partnership on all wood protection matters, and both associations are now focused on one clear priority on behalf of members – to promote the accurate and unambiguous specification and description of treated wood products throughout the UK supply chain. Staff turnover at some merchant outlets and the sheer range of products now handled by many merchants makes the consistent enhancing of product knowledge on one particular material a challenge. The WPA believes that the answer is to keep the message as simple as possible, communicate it through the right channels and keep reinforcing it until it becomes standard practice for both buyers and sellers. The partnership between TTF and WPA, further supported by the Timber Decking and Cladding Association (TDCA), is key to ensuring consistent messaging and maximising the audience reached. www.trada.co.uk

Use classes It is a mistake to assume that all pressure-treated wood is the same. While one piece of treated wood may look much like any other, the level of preservative protection could be quite different. The British Standard for wood preservation, BS 8417,1 requires that the loading and penetration of preservative impregnated into the wood is tailored to the desired end use. Applications for treated wood are therefore grouped into ‘Use Classes’. The challenge is how best to simplify this message while not losing technical accuracy. All three associations have been working together on a two-fold approach, in line with the target markets: • For the fencing, garden and landscaping sector (i.e. for treated wood used in contact with or close to the ground), the focus is on promoting the use of the term Use Class 4 primarily through the WPA’s ‘Make sure it’s Use Class 4’ logo and communications package. • For the broader timber supply chain, the focus also includes differentiating between interior and exterior applications for treated wood – using a bold, colour coded Use Class 2, 3 or 4? message and simplified product descriptions. >>

Protection Preservation

Specification and installation checklist • Establish the Use Class of the timber you need before ordering. • Tell your supplier, in writing, that the wood must be treated to that particular Use Class to comply with BS 8417. Ask them to verify that the wood supplied meets your Use Class specification on the delivery note and invoice or by providing a treatment certificate. • When buying from stock always check to which Use Class the wood has been treated. • NEVER substitute wood that has been treated for an indoor application for use in an external application – failure is inevitable. • Do NOT supply wood that has been treated for external use for internal applications. • For wood in permanent ground or fresh water contact, or providing exterior structural support, Use Class 4 levels of protection MUST be achieved. Anything less and service life, structural safety and customer satisfaction will be compromised. • When cross-cutting, notching or boring treated timber products during installation, ALWAYS apply an end grain preservative treatment to freshly exposed areas – to maintain the integrity of the protection. • NEVER put cut ends in the ground, even if the end-grain has been coated.

For those who need further guidance on what the Use Classes mean in practice, WPA and TTF have also developed three new Guidance Notes on Understanding Use Classes 2, 3 and 4 for Preservative Treated Wood. These include a simple explanation of what national standards require for each end use, which species are most suitable, what preservative penetration to specify for different treated commodities and the necessary quality control criteria.

Protection Fire doors

The role of the passive fire protection installer and maintainer

Ross Newman discusses the importance of installation and maintenance in the protection of buildings.

The workmanship of installers and maintenance teams plays an important role in fire protection.

Protection Fire doors

“Fires and smoke are dangerous but they usually become catastrophic when they spread from the room of origin. The point of PFP is to prevent this spread or, at the very least, delay it. All too often, however, fires do spread, often because of faults with the installation and building management/maintenance.”


well-designed passive fire protection (PFP) strategy and specification are not the only considerations in adequately protecting buildings from fire. Of equal importance is the workmanship of installers and, thereafter, the maintenance team. PFP is built into the fabric of a building in the form of walls, floors, ceilings, beams, columns, screens, seals, firestopping, doors and shutters. It performs two essential functions in the event of a fire: 1. It allows the building to remain stable for a specified period to allow people time to escape and firefighters to attend. 2. It resists the spread of fire and smoke between buildings/ dwellings, or between subdivisions within a single building/ dwelling, helping to protect people or valuable contents within.

Installation PFP strategies comprise disparate elements that together make a critical system. Installing a single one of these elements without an understanding of the overall critical system can lead to integration errors, even when that element is correctly installed. The impact of fire and smoke has the potential to be extremely grave. It can kill and severely injure. It will also destroy or write off fixtures, furnishings and equipment, and fatally weaken the structural integrity of assets. In an industrial setting, this sets up a domino effect of negative impacts, interrupting business and leading to financial losses, lawsuits, redundancies and even insolvency or bankruptcy. Although the risk cannot be eliminated altogether, the impact is so detrimental to operations as to demand efforts to minimise it. Fires and smoke are dangerous but they usually become catastrophic when they spread from the room of origin. The point of PFP is to prevent this spread or, at the very least, delay it. All too often, however, fires do spread, often because of faults with the installation and building management/maintenance. >> www.trada.co.uk

Protection Fire doors

Maintenance Certain elements of PFP construction such as masonry walls or timber or steel structures are likely to remain untouched throughout the life of the structure. They are generally low maintenance and require relatively little vigilance from the point of view of fire safety. Therefore, the main risks arise if they are not installed correctly in the first instance. However, other elements of construction, such as doors and partition walls, suffer from wear and tear or are more likely to be altered and are, accordingly, a higher risk factor. Those that are subjected to daily use, such as doors, shutters and so on, will need to have their fire safety role preserved through a routine programme of maintenance. Equally, elements such as partitions are likely to be altered or penetrated (to allow building services to pass through, for example) and will therefore suffer damage and require repair. The new penetrating element will need effective firestopping. All PFP systems both need to be properly installed at the start of their life and subject to a programme of continuous maintenance by competent persons with the necessary expertise.

Fire doors must be properly installed

Passive fire protection Since many PFP solutions are effectively hidden in the building, they are difficult to put right. More importantly, they are very difficult to verify or detect by cursory inspection, even if the structure is visible. It takes skill, experience and competence to accurately identify the fire rating of an element, especially in the absence of any historic documentation. In some instances it may not be possible to assess the fire rating of a particular element of construction or item of PFP without some form of destructive inspection or investigative testing. Retrospective fixing is, of course, unavoidable in some circumstances, especially where a building undergoes a change of use or working practices are introduced that alter the existing fire risks. In instances like this, such remedial works are likely to be carried out years after original completion and often by non-specialist facilities management staff. The resulting risk is that the occupants could end up relying on systems that may not function as expected in the event of a fire.

Doors can suffer from wear and tear and must be maintained properly


Minimum life-safety aspects of PFP are enshrined in legislation and regulated to ensure that buildings are constructed that provide reasonable levels of protection to life safety and continue to be managed and maintained once the building is occupied. However, owners, insurers and other interested parties will often go further than the minimum legislative requirements, if the risks warrant it. >> Timber 2021 Industry Yearbook

Protection Fire doors

The correct installation of all PFP systems is critically important but of equal importance in the ongoing maintenance so they can continue to provide the same level of fire performance. This has been recognised under article 17 of the Regulatory Reform Fire Safety Order. Similar to installation, maintenance of PFP requires specialist knowledge and skills.

Specification Part of the solution to good installation is to get the specification right in the first instance. A comprehensive specification, clearly defined and accompanied by accurate, comparable drawings, goes a long way to mitigating the risk of misunderstanding between the different parties involved in the design and construction of the building. Wherever possible, only third-party certified, and tested products should be specified to provide added assurance. The specification needs to be effectively communicated as part of the overall strategy, with the integration issues clearly expressed. In this respect, working in a contractual Building Information Modelling (BIM) environment helps.

Installation and maintenance Even after handing over comprehensive specification information and clearly communicating the strategy, success still lies in the hands of the installer. It is not enough to rely solely on the installer’s self-declaration of competency. Instead, you should check that that they have relevant recent experience, and that they can back up their claims with evidence of suitable training and skills. Additional confidence can be provided by using installers that are certified under a recognised UKAS-accredited specialist third-party installer scheme. Indeed, for added assurance insurers and fire consultants are increasingly insisting on third-party certificated services. www.trada.co.uk

Fortunately, there are a number of highly reputable third-party certification schemes for installation and maintenance providers. Successful candidates will typically only be awarded their certificate if they have attended a training course, passed an examination and had their practical site work scrutinised by an independent UKAS-accredited third party. Further assurance is provided with regular audits to ensure compliance with the scheme is maintained on an ongoing basis. This gives the highest possible level of confidence that the work will be carried out correctly. Specifying specialist third-party certified contractors will help demonstrate due diligence in the unfortunate event of a fire. Dealing with the damaging effects of fire is bad enough without the additional burden of being the subject of a legal claim.

Summary There is no question that employing third-party certified installers and maintenance contractors are worth the extra cost for the fire risks they mitigate. Furthermore, installing and maintaining PFP elements correctly extends their service life. Retrospective fixes for poorly installed designs are disproportionately difficult and expensive, adding extra motivation to get it right first time round. n

Fire Door Safety Week: why fire door safety can’t be left to chance With fire safety under the spotlight, and strengthening of legislation through the Fire Safety Bill and the Building Safety Bill, Fire Door Safety Week will once again help to educate on the importance of fire door safety. Helen Hewitt reflects on why there is still a need for the national Fire Door Safety Week campaign.


ike many safety devices, fire doors remain fairly anonymous. We walk past dozens of them every day: at work, at home and when we’re out and about in shops and restaurants. How many times do you give them a second thought? The truth is, many of us don’t think about fire doors until we need them. In the event of a fire, we will be glad they perform the task they are intended to do.

What is a fire door? As an effective passive fire protection product, fire doors form part of the structure that divides a building into individual fire compartments. Their role is to prevent fire and dangerous smoke from spreading into additional rooms and floors while allowing crucial time for occupants to evacuate and fire services to tackle the fire.

So much more than a standard door, a fire door is a complex system of components – including the door leaf, frame, ironmongery, intumescent seals and glazing systems – which must work and perform together to protect lives. To perform as intended, fire doors must be correctly specified, installed and maintained. But how do those responsible for fire doors know what’s right and what isn’t? How do we educate everyone on what constitutes good fire door practice?

Fire Door Safety Week These two questions are what led to the launch of Fire Door Safety Week in 2013. Founded and owned by the British Woodworking Federation (BWF), in association with the BWF Fire Door Alliance, the Fire Door Safety Week campaign exists to increase public understanding of the crucial role that fire doors play in protecting life and property. The original campaign objectives still remain true: • To educate the public on the critical role that fire doors play in delaying the spread of fire and smoke. • To encourage best practice in the use of fire doors, especially when it comes to closing propped-open fire doors and reporting suspected damage – an open fire door or one that is damaged won’t perform as intended in the event of a fire and everyone should take responsibility. • To educate on, and promote, best practice in the specification and installation of fire doors.

Protection Fire doors

The specification and installation of fire doors Since its launch, Fire Door Safety Week has emphasised the importance of getting specification and installation right and how everyone plays a part in fire door safety – from the fire door manufacturer to the architect, through procurement to the on-site installer, and to the landlord and the tenant. When it comes to specification, the person responsible for choosing the fire door, whether an architect, a contractor or a facilities manager for example, must specify correctly according to the need of the building and compliance with legislation, and understand what questions to ask of the manufacturer, such as proof of performance. All fire doors must have the appropriate proof of performance for the ratings they carry. This proof is obtained by subjecting the door to testing to BS 476-221 or to the European equivalent BS EN 1634-1.2 The door is tested as a complete assembly, and can only be assured to replicate the performance if the tested design uses the correct compatible components. The BWF has long championed the third-party certification of fire doors through its BWF Fire Door Alliance scheme. By selecting a fire door that has been third-party certificated,

landlords and residents can have confidence that the fire door will perform as designed in the event of a fire. Third-party certification means that the fire door manufacturer or door processer has been audited by an independent third party to confirm the product is tested appropriately and manufactured to a consistent standard. However, it’s important to be aware that the performance of any fire door is also dependent on the quality of installation, ongoing maintenance and inspection. Installation of fire doors is as life critical as the product specification itself and should only be carried out by someone who is competent, has been specifically trained to install fire doors and understands their responsibilities in getting it right. Installation of a fire door is very different to hanging a standard interior door and correct installation, following a manufacturer’s guidance, means that the fire door will perform as designed in the event of a fire.

A focus on inspection and maintenance Too many fire doors fail as a result of poor maintenance and lack of competent inspection. One aspect of fire door failure that was specifically highlighted in Phase 1 of the Grenfell Tower Inquiry was the removal of self-closing devices. >>

Protection Fire doors

However, there are other key factors that need to be inspected regularly such as: • whether the fire door closes tightly to the frame • if the door hinges are in good order • if the fire door has its intumescent strips intact • if any modifications to the door have been made that are not in line with the manufacturer’s recommendations. Regular inspections for damage will help ensure that a fire door remains fit for purpose; if any issues are found they can be promptly fixed using compatible and correct fire-rated components. While Fire Door Safety Week introduced the Five Step Fire Door Check to empower residents to quickly spot faults with fire doors and report these to the responsible person for immediate action, fire doors must be checked regularly and maintained by competent people.

Fire Door Safety Week 2021 Now in its ninth year, Fire Door Safety Week will take place from 20–27 September 2021. The national awareness campaign still exists because of the fact that fire door safety isn’t where it should be. Join us in making the necessary changes happen and help to promote awareness of the life-saving role that a fire door can play. n

Design steps to stair safety Too often design flair can compromise the safety of stairs presenting a risk of injury, or worse. Kevin Underwood looks at the four design characteristics that can make all the difference to stair safety, without compromising the aesthetic appeal.

Timber 2021 Industry Yearbook

Joinery Stairs

“If the going is 30cm or more, users are less likely to overstep. However, for those steps that cannot be as deep as this, surface finishes that offer high slip resistance should be used to reduce the risk of an accident.”


hen we speak of stair design for dwellings, usually the pressing questions relate to budget, time frame and ease of installation. For one-off bespoke staircases, intricate design details and material specification can be added to the list. But all of these should be considered alongside stair safety, which is paramount.

Stairs present a risk of injury through slips, trips and falls. In the UK it is reported that there is a fall on stairs every 90 seconds1 and, on average, there are 665 deaths in England and Wales caused by a fall on or from steps or stairs each year.2 While personal and behavioural factors can certainly play a part, such as decreased balance or carrying objects up the stairs, the risk of accidents can be reduced by attending to those characteristics of a staircase that affect a user’s ability to use the stairs safely.

Consistent rise and going It is important to understand that when climbing or descending stairs, the brain subconsciously determines the movements that the legs and feet need to take based on experience of the first couple of steps. This makes us all vulnerable to trips and falls if the height (rise) and depth (going) of each step is not consistent, as these variations are unexpected and will often not be recognised by the user. To help prevent accidents due to this inherent human instinct, each step’s rise and going should only vary by + or – 1% throughout the staircase. The going of a stair, its depth, can significantly affect a person’s ability to travel up or down the stair safely. If the going is 30cm or more, users are less likely to overstep. However, for those steps that cannot be as deep as this, surface finishes that offer high slip resistance should be used to reduce the risk of an accident.

Handrails Handrails should be provided to offer stair users added support when needed – and when combined with balustrade (guarding), can also be used as an attractive design feature. Often handrails, even when provided, >> www.trada.co.uk

Joinery Stairs

are not used and many stair users even deem them unnecessary. But they are vital for safety – especially for those who are more vulnerable, such as the elderly. If someone loses their balance when climbing stairs the handrail provides a crucial point of contact for them to grasp, to prevent a fall. For this reason, the handrail needs to be positioned so that it can be easily reached from all points on the stair.

Guarding Staircases should also be designed with suitable guarding to protect users from falls from the side of the stair for all steps at a height of 60cm or more from the floor. The material used for the guarding should be strong enough to withstand someone falling into it and the guarding should be high enough to prevent anyone falling over it. To reduce the risk of accidents in environments where children under 5 may be using the stairs, all gaps in the guarding should be less than 10cm to help stop them becoming trapped. The guarding should also be designed to prevent children climbing, for example, they should not have horizontal rails.

Surface finish The finish of a staircase can be the final touch for a breathtaking design, but it can also significantly influence the user’s ability to use it safely. Wet or dusty surfaces, worn or thin carpets and the various types of hard flooring can all play their part. So when designing the staircase, the slip resistance of the material should be considered. If the depth (going) of the step is 30cm or more users are less likely to overstep, but for those steps with less space for the foot, materials with sufficient slip resistance should be specified. >>

Further information Further guidance on the design and specification of domestic stairs can be found in the Design Guide for Domestic Timber Stairs, produced by the BWF Stair Scheme. This design guide not only covers legislation and standards, but also provides authoritative advice on how a staircase in the home should be designed and set out, to ensure safety and to reduce commonplace concerns such as squeaks and bouncy stairs. www.trada.co.uk

In addition to safety in the design of staircases, careful consideration must also be given to installation. The BWF Stair Scheme has published the Installation Guide for Timber Stairs and is soon to launch an interactive learning tool covering stair installation.
