TRAPEZOIDAL PAVILION ROOFS AND FACADES, CLAD IN AURUBIS’ NORDIC ROYAL GOLDEN COPPER ALLOY, DEFINE THE WELCOMING CHARACTER OF A NEW CHILDREN’S NURSERY BUILDING.
Arcadia Nursery brings together two existing University of Edinburgh nursery facilities, into a single, purposebuilt complex. Although conceived as a free-flowing series of interconnected spaces internally, externally each age group’s playroom is clearly expressed as an inviting and domestic – but also contemporary – form, creating a sense of belonging and ownership for each age group. The resulting three pavilion roofs are clad in Nordic Royal golden copper alloy, as well as some facades complementing adjacent timber cladding.
Malcolm Fraser Architects selected Nordic Royal for its warm and friendly persona, so crucial to a nursery setting. Having used bronze on other projects, the designers felt that this would become too dark, whereas Nordic Royal will stay light, both in terms of the colour and visual weight, sitting well alongside the timber cladding. Double lock, standing seam joints were used to give structure to the pitched roofs but the Nordic Royal wall cladding is installed with a reverse coulisseau joint, avoiding projections that children might catch themselves on at low level.
Nordic Royal is produced by Aurubis, part of the world’s leading integrated copper group and largest copper recycler. Other copper alloys include Nordic Bronze and Nordic Brass – now also available pre-weathered. In addition to Nordic Standard copper, other Aurubis Architectural surfaces include Nordic Green and Nordic Blue factory-applied patinas developed with properties and colours based on the same brochantite mineralogy found in natural patinas all over the world. Nordic Brown pre-oxidised copper gives either light or dark brown oxidisation that otherwise takes time to develop in the environment.

Paul Groves reveals what this month’s articles have in store
THIS MONTH WE TAKE A LOOK AT A WIDE VARIETY OF PRODUCT AREAS, INCLUDING ONE THAT IS BECOMING INCREASINGLY IMPORTANT FOR TAKING A LONGTERM VIEW OF A BUILDING’S USEFUL LIFE - ACOUSTICS.
In practice the noise coming from pipe systems is usually from two sources: first from the sound energy from water and air turbulence in the pipe, but the most noise will be generated from vibration of the pipe as a result of the water flow. This latter source can be transmitted through the wall by the pipe supports or the seals as the pipes pass through different floors.
For the specifier the simplest answer is to use the quietest material possible for the pipes, which independent studies continue to show is cast iron, performing significantly better than the best “acoustic” plastic systems.
“You can reduce the noise from vibration transfer by using special pipe clips, dampners and clamps, all manufacturer’s offer bracket solutions for this purpose, enclose the pipework within a mass of 15Kg/m2 and lag the pipes with 25mm unfaced mineral fibre as described in Building Regulations Doc E,” explains Mike Rawlings, Marketing Manager for Saint Gobain PAM UK.
To find out by how much you can reduce the noise using these solutions, an independent consultancy TVVL in Holland conducted 200 tests on different waste water systems and combinations of noise reduction factors. The tests first measured the noise from bare pipe made from a number of different materials, including cast iron and a number of plastic and acoustic plastic systems without insulation. They used a flow rate of 3l/s, which they deemed comparable to the flow generated by a WC being flushed.
The differences in noise ranged from 61.0dB(A) for the worst performer down to 51.0 dB(A) for a vertical pipe and from 64.5 dB(A) to 50.5 dB(A) for a horizontal pipe. Measurements were taken at offset points and changes in direction. In all cases the best performing or quietest material was cast iron.
TVVL then extended the tests to include the effects of external acoustic insulation and other noise reduction measures.
The tests concluded that if you used both glass wool plus an enclosure constructed from gypsum board you could reduce the noise (or sound pressure level) by up to 30dB(A) in walls. Using acoustic heavy sound proofing in the ceiling can reduce noise by up to 25dB(A).
The report demonstrated that pipe systems can get down to the acoustic levels required for most buildings, but for materials other than cast iron it requires significantly more insulation to do so.
Harnessing the light fantastic
INTEGRATED SYSTEMS ARE THE WAY FORWARD FOR PV TECHNOLOGY. SPECIFICATION TAKES A LOOK AT SOME INNOVATIVE PV PRODUCTS NOW ON THE MARKET
As a fast-growing proportion of the UK population is now realising, you don’t need to live somewhere warm and sunny to benefit from the energy producing potential of solar photovoltaic (PV) panels.
PV systems require light rather than heat, and the UK receives 60% of the amount of sunlight (or solar radiation) that shines down at the equator. And while it’s true that the more light PV panels receive, the more electricity they can generate, just like solarpowered calculators, they still work on cloudy days.
In a single hour, the sun transmits more energy to the earth's surface than the world uses in a year. PV panels and tiles convert this energy into electricity, making it a simple, clean, cost-effective and dependable way to power our lives. PV technology is fast-moving and the range of ingenious and increasingly cost-effective integrated PV products is hard to keep up with.
Solarcentury’s new Sunstation, for example, is building-integrated photovoltaic (BIPV) solar roof system designed to meet customer demand for an aesthetically pleasing yet competitively priced on-roof system.
It has been designed, says Solarcentury, with expert input from engineers, installers and architects. Sunstation “is the result of Solarcentury’s extensive BIPV technical knowledge, together with feedback from installers, accrued over the last 10 years since the launch of the company’s previous award-winning BIPV product”.
Sunstation’s sleek black panels sit low to the roof battens so they’re completely flush with the roof. It is quick and easy to install, Solarcentury explains: “The system clicks together, there’s no unwieldy sub-frame,and it comprises just seven elements; so it can be installed in a day”
An average-sized Sunstation system comprises around half the number of parts
required for a typical on-roof system, the company says, and it is the first BIPV module available on the market that is manufactured on the main PV factory line, rather than assembled by hand. It is this, combined with its low part count, that makes Sunstation cost competitive with on-roof solar systems. “Our research tells us that 90% of installers believe there will be considerably more adoption of BIPV if the price matches on-roof systems,” says Jon Sturgeon, Solarcentury’s head of product development. “We also know that homeowners have always wanted a solar option that preserves the look of their roof,” he adds. Sunstation is tested and certified to the same industry standards as the roofing it will replace.
Polysolar develops, designs, and projectmanages building integrated photovoltaic (BIPV) solutions. The award-winning Cambridge-based developer and producer of innovative low-cost solar PV glass for the BIPV market, describes its unique thin-film solar PV glass as the first truly transparent alternative for conventional architectural building materials, generating renewable energy and a return on investment.
Polysolar’s products provide an attractive finish to a building while enabling environmental targets and building and planning regulations to be met, the company says. “Indeed our contribution to BREEAM environmental assessment method can be sufficient to extend classification by a whole category”.
The Polysolar product range is enhanced by an all black higher powered micromoprh unit (PS-D series). It is also introducing a range of BIPV products that address different architectural requirements, including a new range of high performance transparent glazing panels, facade cladding panels and flexible roofing panels.
Everything you need to know about
Our research tells us that 90% of installers believe there will “ be considerably more adoption of BIPV if the price matches on-roof systems. We also know that homeowners have always wanted a solar option that preserves the look of their roof. “
Installations such as the Willmott Dixon building at the Building Research Establishment in Watford provide the company with an opportunity to showcase the virtues of its transparent product. From this, strategic supply chain links were created, which now places Polysolar as one of the country’s and the world's leading providers of BIPV solutions.
Colour-coordinated PV innovation
Glass and solar products manufacturer Romag recently installed its newly developed terracotta-coloured Intecto integrated solar tile at Gentoo Homes’ Beechbrooke site in South Shields.
The Intecto tile has been designed with aesthetics in mind, to blend seamlessly with terracotta concrete and clay tiles. It is also available in black, grey and brown “and can be tailored to work with almost all tiling systems". “At Gentoo we are always striving to be innovative and deliver high environmental standard across our developments,” says managing director Barry Walker. "Our customers have been asking whether solar can be incorporated into our housing developments as they recognise the value of renewable energy and the financial benefit this technology can deliver. We are delighted to be the first to install Romag's innovative Intetco system here at Beechbrooke."
PV technology explained
Photovoltaic technology is the term used to describe the hardware that converts solar energy into usable power, by generating electricity from light.
At the heart of photovoltaic (PV) technology is a semi-conductor material which can be adapted to release electrons, the negatively charged particles that form the basis of electricity. The most common semiconductor material used in photovoltaic cells is silicon, the element most commonly found in sand, which also happens to be the second most abundant of the materials comprising the earth's mass.
PV cells have two layers of semi-conductors, one positively charged and one negatively charged. When light shines on the semiconductor, the electric field across the junction between these two layers causes electricity to flow, generating DC (direct current). The greater the intensity of the light, the greater the flow of electricity.
British-made and built to last
FOR A NUMBER OF YEARS, THE RISE OF OVERSEAS MANUFACTURING HAS BEEN INEVITABLE WITH CHEAPER FOREIGN-MADE GOODS FLOODING VIRTUALLY EVERY UK MARKET. NOW IN THIS AGE OF AUSTERITY, WHEN PRICE TRADITIONALLY BECOMES AN EVEN MORE DECISIVE FACTOR, DOMESTIC MANUFACTURERS ARE ENJOYING A LONG-OVERDUE REVIVAL AMID AN EXPLOSION OF CONSUMER INTEREST IN QUALITY, BRITISH-MADE GOODS.
As our shops, roads and homes have been swamped with foreign imports, this has had a devastating impact on a manufacturing industry that was once the envy of the world. Government after government may have done little to stop this on-going demise, but some British-based manufacturers are fighting back.
Based in North London since 1946, the Lonsdale Metal Company has been supplying patent glazing and rooflights to the commercial and residential sectors for close to 70 years. So where has Lonsdale succeeded where so many others have failed? The family business prides itself on understanding its customers and strives to deliver guaranteed quality and added value with every single product.
Construction has always been ‘price-driven’, but in some sectors – such as glazing and rooflights – this is beginning to change. Driven by the customer demand for quality products and the need for manufacturers to survive the competition, quality has also had to increase against the background of improved standards worldwide.
In the rooflight industry where new technology comes thick and fast, companies must do the same as any other sector with success reliant upon quality, service and product development. Manufacturers have to retain focus on their product, employees and target market if they are to thrive – especially when contending with tightened regulations, the on-going recession and an influx of foreign imports.
“We have been supplying the glazing industry with aluminium systems since the 1940s,” said Stephen Burgess, Managing Director, Lonsdale Metal Company. “Our customers, technology and the industry may have changed but our ethos will always remain the same – to offer well designed, easy to install products at the lowest possible prices without any compromise on quality.” Lonsdale’s customers, rooflight and glazing contractors, rely on suppliers and manufacturers that can deliver quality time and time again. As manufacturers invest a lot of time and effort into delivering design and performance standards to give clients peace of mind, it is vital that contractors utilise this expertise to pass quality on to their customers. And the manufacturer must not forget the end user.
According to a 1998 report by the Construction Task Force, “the construction industry tends not to think about the customer”. Little may have changed over the last 17 years as many construction companies still complete little research on what the end user actually wants, nor attempt to raise customers' aspirations or educate them to be more discerning. But Lonsdale continues to buck the trend.
For building and home owners looking to avoid dreary, cheap and cheerful plastic systems, the aluminium and glass roof from Lonsdale can be a competitive alternative. Combine this with the system’s 40 year design life and low maintenance and Lonsdale delivers exactly what the customer wants – a rooflight that is built to stand the test of time.
Lonsdale rooflights feature on some of UK’s most prestigious, famous and iconic buildings – including 10 Downing Street, Buckingham Palace, Windsor Castle and the British Museum. A quintessentially British company that achieves success against the odds, Lonsdale continues to set the standard for rooflight packages with the system of choice for discerning homeowners, the Royal Family and the Prime Minister.

Single ply: get it right first time
DECADES OF RESEARCH AND DEVELOPMENT HAVE GONE INTO THE DESIGN AND MANUFACTURE OF MODERN WATERPROOFING SYSTEMS, AND SO IT’S VITAL TO GET THE SYSTEM SELECTION AND INSTALLATION RIGHT FIRST TIME. NOW, WITH CONSTRUCTION SITES FACING EVEN SMALLER BUDGETS, TIGHTER DEADLINES AND EVER MORE STRINGENT BUILDING REGULATIONS, THE QUALITY OF THE WATERPROOFING SPECIFICATION HAS NEVER BEEN SO IMPORTANT.
Waterproofing typically accounts for only 3 - 5% of a project’s overall budget but it must never be undervalued. With water ingress a key factor in up to 75% of building failures post-construction, the waterproofing membrane is the first line of defence and so should be considered at the earliest possible stage in the design and build process.
How can you be sure that your waterproofing system will deliver proven performance and remain watertight in the long term? With a proven track record and designed with an efficient installation process in mind, SikaTrocal single ply roofing membranes combine long term performance, fast application and an unrivalled freedom of design that make them ideal for virtually any roof application.
Longevity is key
Whether obvious or unforeseen, roof problems cause disruption and are a significant expense to building owners. Unfortunately, problems will be inevitable as the roof ages and deteriorates so it’s vital to choose a roofing membrane that delivers long term performance with an application that is relatively simple, quick and hassle-free.
Single ply can provide one of the best all round solutions to achieve cost effective, durable and sustainable systems. Single ply roofing membranes generally have a design life of in excess of 30 years, ensuring whole life performance is maintained whilst minimising the impact on the environment.
Speed of the essence
Single ply ensures today’s fast track programmes can be met on site. Providing a quick and clean approach, they achieve initial waterproofing rapidly so that the concrete ground works can commence very early and minimise disruption on site by avoiding hot melt adhesives.
Mechanically fastened roofs are generally the fastest and most economical to install and because of their lightweight nature, will often enable savings to be made on the supporting structure. The Sika-Trocal disc fixed method secures both membrane and insulation with one fixing, reducing labour costs and minimising the amount of fasteners by up to 50% when compared with traditional Single Ply mechanical fixing methods. As well as offering speed of installation, single ply membranes offer many other benefits. The selection of a high performance, low maintenance single ply roofing system will help to prevent heat loss, as well as water and air penetration, to create a waterproof, thermally efficient building envelope. This will add value where it matters –on the bottom line.
Proven to perform
Once the single ply membrane and installation method has been specified, the relationship between the manufacturer and the roofing contractor becomes absolutely crucial. Sika-Trocal operates an approved contractor scheme that will assure the client that their roofing system will be installed by a high quality and trusted applicator.
By utilising the expertise of the manufacturer and producing highly detailed plans before the project begins, you can get the job right first time, every time. Whatever the project, specifiers, contractors and their clients must turn to manufacturers and designers they can trust to ensure a quality specification that meets the very highest standards.
Whether mechanically fixed or adhered, coloured or black, lacquered or not, single ply still provides one of the best all round solutions to achieve cost effective, durable and sustainable systems. For high levels of performance, a fast and clean installation, long term guarantee, industry standards and versatility – choose a single ply waterproofing membrane that will always come out on top.
Ahead of its time
WHY IS A CONCRETE INNOVATION DEVELOPED A DECADE AGO EXPERIENCING UNPRECEDENTED GROWTH SINCE THE RECOVERY? GAVIN WHITE, PRODUCT MANAGER AT MARLEY ETERNIT, DISCUSSES THE RISE OF THIN LEADING EDGE CONCRETE SLATES AND WHY THEY ARE HELPING SPECIFERS TO MEET THE BUDGETARY AND AESTHETIC DEMANDS OF TODAY’S PRIVATE HOUSING MARKET.
Thin leading edge interlocking concrete tiles, made to replicate the look of natural slate on a budget, are not a new invention. In fact, one of the first products launched into the market was our own Edgemere slate, over a decade ago. While sales have grown steadily since it was launched, we have seen sudden unprecedented demand since the recovery, particularly in the last year.
With the wider financial recovery and schemes such as Help to Buy giving a significant boost to house building, it is really no surprise that demand for all roofing products has grown significantly in the past couple of years. However, we have noticed that sales of our thin leading edge concrete slates are disproportionately high. Since the start of 2012, demand has more than doubled and we have seen a 46% increase in the last year alone. The biggest increase has been in private housing development, while it still remains popular for both social housing new builds and refurbishment.
So, what is driving this growth in specification for a product that has been around for ten years?
Getting a premium aesthetic for a small budget is the driving force behind the surge in specification for thin leading edge concrete slates. Not only are they a cost effective alternative to natural slate but they are also an affordable upgrade to standard concrete interlocking tiles.
One particular trend we have noticed is the use of our Edgemere slates on new private housing developments seeking to differentiate themselves with a contemporary exterior and high internal specification. Using a concrete interlocking slate over a standard tile gives specifiers the chance to elevate the exterior aesthetic, giving a premium slate look without much additional cost, enabling them to maximise the external look on a budget and in turn, spend more on internal specifications.
There has clearly been an aesthetic shift in private housing, where specifers seek a sleeker slate look. Fifteen years ago, it would have been fairly common practice for a development of four bedroom houses to all be roofed in traditional interlocking concrete tiles. However, these days a development like this often has thin concrete or fibre cement slates to give a more contemporary aesthetic.
New innovations over the past couple of years have also made these slate effect tiles even more convincing. For example, we launched a riven version of Edgemere, which has proved popular with specifiers looking for a closer match to natural slate to meet planning requirements.
In addition, the added environmental value they bring is a key factor in their specification. Independent carbon certification, the ability to achieve an A+ rating in the BRE’s Green Guide to Specification and certification to the BES 6001 standard for Responsible Sourcing, means they can help to achieve extra material credits under one of the current UK environmental assessment methods.
With the ability to help specifiers meet the budgetary, sustainability and aesthetic challenges of today’s competitive market, we expect that thin leading edge concrete slates will increasingly become the standard specification for new housing.

Howarth makes waves at Mercia Marina
THERMALLY TREATED REDWOOD CLADDING AND DECKING FROM HOWARTH TIMBER AND BUILDING SUPPLIES HAS BEEN INSTALLED AT MERCIA MARINA IN DERBYSHIRE, TO CREATE A STUNNING FINISH WHICH REMAINS IN KEEPING WITH THE NATURAL SURROUNDINGS OF THE BUILDING.
The marina, in Willington, is Europe’s largest inland marina and boasts a plethora of biodiversity and wildlife. Howarth’s cladding and decking therefore suits the surrounding natural environment whilst ensuring a sleek appearance in its high profile location.
The high quality Thermo-D cladding, which was installed at The Boardwalk - the marina’s retail accommodation - co-ordinates aesthetically with the thermally treated redwood decking which was also selected for the marina.
The Boardwalk boasts a bar and restaurant in which customers can wine and dine, along with a farm shop and a host of boutique retailers.
Not only was the premium thermally treated redwood chosen for its aesthetic properties, it was also specified due to the lack of use of chemicals during production, which enhances the environmental qualities of the building. It was also bespoke to the project, having been UV treated and then brushed to reveal the grain.
Further benefits of the cladding and decking include its ability to maintain the same size and shape, its durability, stability and strength. The timber is PEFC certified has a decreased risk of mould and improved thermal and hygiene qualities.
Along with this, the timber offers improved wood preservation and weather resistance and can be painted, stained and fire treated to class 0.
Robert Neff, partner and general manager at Mercia Marina, said: “To suit the location, we very much wanted a wood cladding that would maintain its natural word colour and be robust. The Howarth Timber wood we used promises both. The building is now a landmark in South Derbyshire and looks fantastic.” Phil Barman of Howarth Timber, said: “Timber cladding and decking is increasingly being specified by local authorities, architects and developers, largely in part for its environmental credentials, but also for its ease of working, natural beauty, performance and competitive price.
“Timber is one building material that has unrivalled pedigree for use in construction, which is why timber is an ideal choice for use as an external cladding and decking.”

Building for the Future
THE UK’S LARGEST UNDERCOVER COAL YARD AND CASH AND CARRY HAS RECENTLY BEEN CONSTRUCTED BY SCM CONSTRUCTION USING RUUKKI COMPOSITE PANELS TO THE ROOF AND WALLS.
Situated near the Pennines in Halifax, West Yorkshire is a new and exciting energy distribution centre serving domestic and industrial customers with solid fuel, bottled gas and air products compressed gasses, seven days a week.
Future Proof Building
Ace Energy has been trading on the existing site for almost 20 years and decided to make the improvements to future proof the building and to offer a new way to store and distribute its fuel products. The owner wanted to create a legacy for his years in business that he could always be proud of and requested that the contractor SCM approached the project in the same way.
First Class Composite Panels
Two large warehouse facilities have been constructed giving extra capacity to store a total of 8500 tonnes of solid fuel on pallets and 1500 tonnes of loose coal in the undercover coal yard. Ruukki SP2D wall panels and SP2C roof panels were chosen by SCM because of their high quality and good looks, they are also very easy for the contractor to work with on site. SCM appreciated Ruukki’s interest in the project and efforts to ensure deliveries and requirements were met and that time schedules were adhered to. This level of detail helped deliver a superb project on time and to such a high level of execution.
Bespoke Solution
SCM who have over 20 years’ experience in the industry, were recommended to the client. They designed the colour scheme and aesthetics that were bespoke for the client in order to achieve the exact look he was trying to attain. This project is the forth and largest SCM have constructed using Ruukki composite panels and more of similar developments are already in the pipeline.
Access Restrictions
All works were carried out around the day to day operations as the site remained operational throughout. However, there were access issues on this project, that to many people, appeared to be insurmountable. To the rear is a river and at the gable end permission to work on the neighbouring land was rejected. In these areas handling 12m panels safely and efficiently made many back away from the project. The solution was to install the panels from the inside of the building which was done expertly and without causing delays on site.
“The client on this project is absolutely delighted with the end result and I am looking forward to duplicating projects of this nature and can only see that our company success in this regard will be using Ruukki as a partner for materials,” said Nick Beresford, SCM Construction.
Complete Energy Efficiency
Not only is this building aesthetically pleasing on the eye but is energy efficient in itself and the benefits can also be passed on to the consumers. Due thermally efficient and air tight Ruukki composite panel construction customers can save up to 15% moisture content on solid fuel products and therefore receive extra volume of fuel on each purchase.

Levolux shapes up at Mabledon Place
A transformed 1970’s office block at One Mabledon Place in central London has been reborn as ‘The Halo Building’, with the addition of a distinctive roof screening solution, from Levolux. The 80,000ft2 , eleven-storey office building, which is attached to a five-storey annex building, was originally home to the trade union Unison. Following a multi-million pound refurbishment project it has been completely refurbished inside and out, including alterations to its existing facade and extensive roof level works. Located on one of London’s busiest high streets and designed to achieve a BREEAM ‘excellent’ rating by Bennetts Associates, the project demanded meticulous planning and a collaborative approach, particularly when it came to delivering the highly visible roof screening solution. As the UK’s leading solar shading and screening specialist, Levolux was chosen to, supply and install a custom screening solution, comprising vertical mesh panels, topped by extruded aluminium Aerofoil Fins, arranged into horizontal panels. In total, Levolux installed 244m2 of fixed, vertical mesh panels, measuring 2.3 metres high, extending around the perimeter of the roof. The vertical panels are designed to screen unsightly plant and equipment from view. Each panel is formed from galvanised steel for long lasting good looks and features rectangular perforations measuring 76mm by 25mm.
Above the vertical mesh panels are 62 horizontal panels incorporating 12 Aerofoil Fins. Each Fin measures 100mm deep by 23mm thick, and is fixed between aluminium side plates. The horizontal panels are fitted within a steel frame by others, allowing them to project 1.9 metres out across a perimeter walkway and an outer balustrade, extending past the building’s external envelope.

H+H has lowered the density of its High Strength and Super Strength Grade Celcon Blocks from 750 kg/m3 to 700 kg/m3, leading to an improvement in thermal conductivity and lighter weight blocks. The change has been accredited by the British Board of Agrément (BBA) in a new certificate issued to the manufacturer. The thermal conductivity of the blocks is now 0.18 W/mK, down from 0.19, bringing about greater thermal performance, enabling U-Values to be reduced further and diminishing heat loss at junctions. High and Super Strength Grade Celcon Blocks are available in thicknesses of 100mm, 140mm and 150mm.
