Foreword

07

Joined up timber I have had the pleasure of being a member of the TRADA Board of Directors for the past four years and have always been impressed by the strength of leadership represented by our Chairmen and the enormous commitment of Andrew Abbott and the staff of TRADA Technology.

I look forward to the next two years working with them as Chairman and hope we can serve our members well – for they (you) are our lifeblood.

During 2010, Simon Fineman and the Board worked hard with Andrew and TRADA Technology to develop a Vision1 that expresses our aims for the future. It is clear and ambitious. This will be our guide and inspiration for the coming years and it ensures that the Board and I will expect to see some new ground covered in the coming year.

It is no coincidence that the Board has chosen to depart from the tradition that the Chair is chosen from Corporate Membership and has gone with a Professional Member from a practice of engineering consultants – Buro Happold. I am delighted that they have made this move, recognising that TRADA’s importance now stretches right across the spectrum of the timber industry. I am looking forward to doing what I can to help see TRADA achieve its goals.

Timber is a phenomenal material. It is a serious contender for construction – used alone and used compositely; used simply or used in complex, highly processed forms. A material that takes in carbon while it grows – taking sun, water and some soil nutrients to make itself. It starts off carbon negative when it enters the material supply chain. The greatest carbon cost is in processing and transport from where it grows to where it is needed.

But the rebirth we’d all expect to see as the world starts to take carbon seriously has not yet materialised. What is holding us back?

One explanation has to be the disconnection between the people who grow wood, the people who make things from wood and the people who build buildings.

Personally I found a chance to use timber on projects such as Norwich Cathedral Refectory, Alnwick Garden Centre and Douai Abbey. This showed me how different the industry is from the more conventional steel and concrete industries so beloved of the construction industry. To put it simply, it is not joined up. It can be hard to get things built in timber.

TRADA is a ‘knowledge organisation’ and it has the potential, through its membership, to be a vital connector between the parts of the industry.

This is a role we want to focus on strongly in the future to help make a more joined up industry.

We also need to ensure that timber takes its rightful place in the minds of teachers and students so that it is considered equally alongside steel and concrete as a key construction option for designers and specifiers.

This is a special focus for TRADA right now.

The coming year will be interesting and I hope you will find the work of TRADA helping your own business. Certainly I’d like to take this opportunity to wish you a successful year whatever your interest in the world of wood.

Timber Expo aims to inform and inspire The UK timber sector’s premier exhibition continues to go from strength to strength as the industry gets right behind it “If the timber industry can act together, it can achieve big things.”

That is the consistent mantra from TRADA Marketing Manager Rupert Scott as he continues to urge timber businesses to back the new Timber Expo show and realise the collective benefits of conveying the strengths and innovative nature of the timber industry.

• • • • • • • • • •

27 & 28 September 2011 Venue The Ricoh Arena, Coventry 6,000m2 Jaguar Exhibition Halls At least 100 exhibitors Target 5,000 visitors from the UK and overseas In Touch with Timber conference integral to the show The Wood Awards 2011 co-located at the Ricoh Timber Buyers Forum launched FREE Timber Talk seminars Timber Tours hourly

Timber Expo is backed by TRADA Technology with International Timber and The American Hardwood Export Council announced as major sponsors – and B&K Structures, Grainger Sawmills, Swift Training School and Timbmet all taking gold sponsor packages too. Add to this the silver sponsors – Coillte, GangNail, Norbord, and Lathams – and you can see that the event is really gaining momentum and gravitas.

products, from flooring, cladding and decking, to timber frame, SIPs, glulam, LVL, cross-laminated and timber protection products.” He added, “Visitors are to be offered tours of the show tailored to their requirements, so they could see cutting-edge products most relevant to their business. “

Numerous companies have taken bronze sponsor packages and many more companies have taken standard exhibition space and taken advantage of the competitive and comprehensive packages on offer.

An added visitor attraction will be TRADA’s annual In Touch With Timber (ITWT) Conference, which is being relocated to the Ricoh from its established London venue.

“We see Timber Expo presenting a vision for timber in construction – and without a vision businesses perish,” Mr Scott said. “But we need the industry to be engaged. It needs the timber industry to be with us and will only succeed if it’s a show for the industry, with the industry.”

“The conference will be an integral component,” said Mr Scott, adding that TRADA aims to have some big name architects and engineers among the speakers. The format for the Conference is being invigorated too. ITWT will be modular, permitting delegates to choose key modules/themes that they wish to attend and dip in and out to suit their requirements, thereby permitting plenty of time to view the exhibition in parallel.

TRADA chief executive Andrew Abbott said the show is needed to provide face-to-face contact between the timber supply chain and its customers across the building sector. “The aim is to provide a forum for easy knowledge transfer, to show the best the timber industry can offer; the products and services that can help bring building projects to life and persuade the sector to use timber more often.”

Timber Expo is also aiming for 5,000 visitors from across the timber using and specifying sectors – both in the UK and internationally. To hit that target, it will need to be “more than an event where people walk up and down corridors putting product leaflets in a carrier bag”, said Mr Scott.

“We must have an event with breadth and depth that both informs and inspires the audience,” he said. “We need it to be a showcase for innovative

In another major step forward for the industry, The Wood Awards will now be co-located with Timber Expo – providing a celebration of timber in architecture and ground-breaking structural engineering. Add to this the Timber Talks seminar programme and the dynamic Timber Buyers Forum, designed to facilitate B2B transactional meetings, and you begin to get a flavour for the stimulating event that Timber Expo will be.

The venue for the event – the Ricoh Arena in Coventry – has been selected for its modern facilities, central location and easy access by road and rail. Exhibitors will have a wide choice of meeting and seminar rooms and the option of having an exhibit in a product showcase area. Exhibitors are even provided a Literature Consolidation service and a Stand Graphic

Pack option to make the planning and build up to the show as smooth and as hassle-free as possible. Add to that the radical, by conventional exhibition benchmarks, stand package option and you begin to see how competitive and attractive the event is to the timber industry.

The fully finished stands, which range 6-24m², cost £300/m² – significantly less than the UK’s exhibition average, when you consider that the price includes electrics, furniture, literature racks, lighting, wi-fi connection and refreshments for exhibitors throughout the show. The aim is to make the show cost transparent – with no hidden extras and great value for money.

Timber Expo will provide marketing support to help exhibitors make the most of the event through the ‘How to exhibit’ guide and an exhibitor briefing day. Additional support includes an online digital magazine – Timber Expozine – giving show updates and a unique interactive website where exhibitors can book or reserve a stand, and update details of what they’ll be showcasing.

A marketing booster pack option gives exhibitors added profile and a range of sponsorship opportunities, from branding exhibition signage to

17

sponsoring shuttle buses from the station, all providing additional means of standing out from the crowd.

Timber Expo has formed an exhibitor steering group to help shape the event planning and to ensure that the needs of exhibitors are met. “The best industry events develop through working in conjunction with those who get the most out of them,” said Mr Abbott.

Timber Expo looks set to be a success, but Event Director Loretta Sales stressed, “we are keen that potential exhibitors get on board as early as possible to take advantage of our pre-event marketing programme. Their marketing begins the minute they commit to the event. We also need to make certain that our visitor profile and numbers continue to develop at a pace and we have opened the visitor registration online right from the launch event.”

Visiting Timber Expo is FREE. Registration is online and early registration means that visitors will be constantly updated with new information ahead of the show.

Timber frame

Zero-carbon Passivhaus is timber frame Joe Martoccia, director of the UK Timber Frame Association, explains why timber frame is the preferred system for achieving the onerous Passivhaus standard for low-energy housing Timber frame is now regarded as the most efficient way of building truly sustainable, energy efficient homes and, while the traditional build sector plays catch up, timber frame continues to push the boundaries of every aspect of housing innovation and sets the standard by which zero carbon homes will be achieved by 2016.

Figures from independent timber research company timbertrends reveal that one in four new homes built in the UK is timber frame and, despite the economic recession, timber frame continues to take market share and is expected to lead the housing market out of recession.

While timber frame continues to form the housing landscape of the future in both the private and social housing sectors, it cannot be ignored that it also forms the fabric of the UK’s most exemplar housing schemes that will define the way the housing community achieves zero carbon housing. This is best demonstrated at this development that achieves Passivhaus standard.

Designed by bere:architects and with timber frame provided by UKTFA member Holbrook Timber Frame, these houses form the central feature of Future Homes, a demonstration centre for sustainable development and construction, part of the 2010 National Eisteddfod festival of Wales.

Future Homes is a joint initiative by the United Welsh Housing Association, BRE, Blaenau Gwent County Borough Council and the Welsh Assembly Government which saw the appointment of bere:architects to design low-cost houses that showcase the Passivhaus concept.

The completed houses feature a range of innovative measures for energy efficiency and eco excellence and are sited next to each other at The Works, Ebbw Vale, a disused steelworks that is the site of the 2010 National Eisteddfod.

Neil Smith of Holbrook Timber Frame explains why timber frame is the natural choice to achieve Passivhaus standard: “Achieving Passivhaus standard, and Code Level 6, is a very real issue for the housing

community and this scheme demonstrates that low-cost housing can be achieved with excellent sustainability credentials, superb thermal efficiency and excellent design. With increasing pressure to deliver more social housing over the next four years under the Coalition Government’s Spending Review, the real significance of The Lime House and The Larch House, could not have been anticipated. They represent a blueprint to which all future housing should adhere.”

Sited next to each other, the houses are certified Passivhaus. Their energy needs are met by harvesting heat from sunshine via extensive glazing and thermal and photovoltaic panels, and by using heat from the bodies and the electrical appliances of the occupants. Hardly any fossil fuel energy is used and The Larch House generates enough energy from the sun in the summer to fulfil all its energy requirements throughout the year. Neil Smith continues: “In order for the low-energy, renewable sources to heat and cool at their optimum, the building fabric has to perform extremely well, preventing generated heat from escaping during the winter, yet allowing cooling in the summer. Getting the fabric right in any home is critical to achieving an energy-efficient environment – you can add as many environmental bolt-ons as you like but if the fabric of the building isn’t performing efficiently then any advantages achieved through the addition of add-on systems will be compromised.”

The Lime House – Simple yet one of the UK’s most energy efficient houses The two-bedroomed Lime House – named after the lime render on the outside walls – follows the unfussy form of a traditional Welsh cottage. Its simple, compact shape minimises the surface area from which it can lose heat, as well as the amount of insulation it needs, which means a greater share of the budget can be spent on the quality of other elements.

The Larch House – A Zero Carbon Passivhaus The Larch House earns credits for criteria Ene 1,2 & 7, and it meets Level 6 in the Code for Sustainable Homes1. This the first time that all three criteria have been achieved in a single house in the UK and Code 6 classifies The Larch House as ‘zero carbon’.

The three-bedroom Larch House is a classic Passivhaus, but one specifically designed to perform passively in the harsh climate and misty winters of a Welsh heads-of-valley location. Large amounts of glazing capture all the available heat from the sun – even from an overcast winter sky. The extra glazing also creates a brighter, lighter living environment and fantastic views. Solar thermal and photovoltaic panels on the roof generate energy from the sun.

The Larch House – named after its Pembrokeshire larch cladding – is built of Welsh materials and features a Welsh timber frame structure at its heart. “The timber panels must fit together very tightly to satisfy Passivhaus draught-proofing and moisture control standards,” explains Neil Smith. To achieve this Holbrook and bere:architects designed the panels to include draught-minimizing details originally developed on Passivhaus developments in Germany and Austria. The final air test of 0.19m3 per hour per m2 at 50Pa achieved one of the UK’s best ever results: almost three times better than the air change rate actually required for Passivhaus certification.

Supporting Services The UK Timber Frame Association (UKTFA) is the trade association representing over 85% of UK timber frame manufacturers and the sector’s key suppliers UKTFA assists the UK construction industry in exploiting the benefits of timber frame - high thermal efficiency, cost effectiveness, sustainability, acoustic excellence, durability, speed of build and design flexibility Visit www.uktfa.com or telephone 01259 272140

Lime House uses locally sourced and manufactured goods and materials wherever possible. Welsh skills, suppliers and products have made the Lime House one of the most energy efficient and cost effective houses ever built in the UK. All of the windows and front door use Welsh larch timber, thermally modified in Anglesey. Developed and taken through certification by bere:architects, these are Passivhaus certified doors and windows; most of the timber for the doors, wall panels, floor slabs and roof elements is from Welsh forests; most of the insulation is made in Wales, and the roof tiles come from a factory only two miles away. The staircase, the stonework and even the solar panels have all been made in Wales.

The timber frame system adapts framing techniques from German and Austrian Passivhaus dwellings for use with faster-growing, softer Welsh timber. The panels are filled with Welsh-produced insulation off-site then clad with two further coats: a thick layer of natural loose-fill wood fibre on the inside, and the same depth of rigid wood fibreboard on the outside, rendered with a thin coating of lime render.

Passivhaus design relies on a high quality ‘tea cosy’ effect maximising the use of super insulation and stringent draught free construction and paying meticulous attention to the removal of thermal bridges. bere:architects collaborated closely with Holbrook’s technical department in developing the extremely rigorous thermal bridge elimination details. All details were thermally modelled by bere:architects with most junctions achieving negative psi values. Timber frame construction, together with the technical expertise within the timber frame sector, has proven itself to be perfectly suited to these highest standards.

The zero-carbon challenge Robin Lancashire, head of TRADA Technology’s Building Performance Section, discusses how timber frame is responding to demanding thermal regulations As thermal performance requirements get ever tighter, the construction industry is grappling with new SAP calculations, psi values and novel construction products, to achieve reduced CO2 emission requirements. The need to construct buildings with zerocarbon emissions is now only a few years away, but innovation in construction historically moves at a snail’s pace. Timber frame construction already has many of the answers needed to meet the bold zero-carbon goal, which is why it continues to improve its market share as building regulations tighten.

Within certain parameters, designers have freedom to choose how they achieve the CO2 emission requirements of the Building Regulations. By specifying well-insulated key elements such as walls, they have greater freedom and the ability to relax other areas of energy saving or energy producing building specification – or go on to achieve a building that far exceeds current target CO2 reductions. For a building designer, the choice of a timber frame wall, with excellent thermal performance, is an obvious way to deliver that design freedom.

Timber frame construction can offer external walls with high thermal insulation for a relatively slender thickness – and timber frame walls do meet their theoretic U-value. Over recent years, we have seen the timber frame industry moving from 90mm to 140mm external wall studs. This provides additional space for installing insulation. Reflective breather membranes have also been introduced to effectively block infrared radiation, enhance the thermal performance of the airspace and consequently increase the overall U-value of the construction.

Nobody wants thicker walls: firstly, they reduce the useable floor area of a building, secondly, they cost more to construct and, thirdly, more energy is used to manufacture more materials. Novel insulation products, reflective vapour control layers and airtight membranes all deliver better thermal performance. With the insulation and the timber structure of your typical timber frame house sharing the same sectional space within a wall, brick clad timber frame external walls’ thickness can be kept below 300mm,

while delivering U-values of 0.20 W/m2K or less and maintain a cavity.

Choose a cladding such as timber, brick slips, or render on battens instead of brickwork and external wall thickness can be reduced still further along with the amount of embodied energy used.

The requirement to test the air permeability of new dwellings was a major change in Approved Document L 2006. The air that we warm up in our houses during the winter leaks out at an alarming rate. By reducing air permeability, we reduce the amount of warm air escaping, so reducing the volume of air we need to heat, reducing our fossil fuel bills and reducing CO2 emissions.

Learning from really cold countries Canada and Scandinavia are places that suffer extreme winter conditions and their choice of building systems must therefore address the issue of keeping a howling gale of minus 30o outside, while maintaining a comfortable environment inside, without using vast quantities of carbon-based fuel. Those countries that have championed the benefits of airtight buildings for many years also happen to be those that have championed timber frame for just as long. This is not a coincidence. Tried and tested techniques and details from overseas are now becoming commonplace in the UK. The polythene vapour control layer which is typically used in timber frame construction now fulfils a second important role in the UK, that of an air barrier. The current default of 10 air changes per hour/m2 of external wall area at 50Pa pressure difference can easily be achieved with timber frame construction. Indeed, the Canadian R2000 timber frame house system prides itself on achieving just 1.5 air changes per hour. The UK construction industry has a lot to learn, although some manufacturers are rising to the zero-carbon challenge.

When air tightness levels below 5 changes an hour are anticipated, it is recommended that a mechanical ventilation heat recovery system (MVHR) be installed as part of the construction process. Warm air extracted from rooms such as kitchens and bathrooms is ducted through a heat exchanger, which collects the heat from outgoing air and uses it to heat fresh incoming air. This allows plenty of fresh air for the building occupants and moist stale air is extracted at source. It takes less than 100W to run a system, considerably less than the heat energy it recovers.

Timber frame

Well-insulated, airtight timber frame buildings work well in summer, keeping daytime heat out – as proved in certain areas of Canada and the US where summer temperatures are stifling. Unlike their traditional masonry equivalents, their lightweight structure does not absorb heat well, so it cannot contribute to the excessive and uncomfortable night time temperatures many people experience in summer as masonry walls release their stored up daytime heat. In winter, timber frame building’s quick heating response time can be appreciated. Without a heavy energy-absorbing internal structure to heat up first, occupants benefit from a fast heating response, on demand, while benefiting from low heating bills too.

Meeting new 2010 regulations The 2010 edition of Approved Document L came into effect from 1st October 2010. For the first time, calculations for thermal bridges are required, otherwise poor backstop values have to be assumed. Thermal bridging occurs in all construction types and is caused by areas of reduced insulation, or where an element passes through the insulation.

Thermal bridging increases space heating requirements by allowing heat to flow more easily through the thermal envelope. In winter, this creates low surface temperatures around the thermal bridge, leading to an increased risk of surface condensation.

Wood has a lower thermal resistance than the insulating materials placed between the framing members. Therefore greater heat flow occurs through studs, plates, rails and joists than in other areas of the external wall or roof structures. This increase in thermal conductivity is referred to as thermal bridging. In general, thermal bridges can occur at any junction between building elements or where the building structure changes. Many other building materials have lower thermal resistance than timber and could be significant factors in thermal performance. For example, a steel post within a timber frame external wall would create a significant thermal bridge unless it was detailed not to bridge from the warm side to the cold side.

Party walls partly sheathed

27

The property that describes the heat loss associated with a thermal bridge is its linear thermal transmittance ψ. This is a property of the thermal bridge and is the rate of heat flow per degree per unit length of the thermal bridge that is not accounted for in the U-value of the plain building element or elements containing the thermal bridge.

TRADA Technology provides publications and consultancy to help the construction industry understand and apply these new considerations to exceed minimum Building Regulation requirements.

Old thinking challenged The new Part L also brings party walls under the microscope for the first time. Previously, they were assumed to have ‘perfect’ thermal performance, achieving a notional U-value of 0 W/m2K. This was because both sides of the wall are within the heated envelope of a building, so there should be no temperature differential from one side to the other, and therefore no heat loss.

However, research conducted in 2005 – 2007 by a team at Leeds Metropolitan University, as part of the Stamford Brook field trials, showed that masonry cavity party walls allow a significant amount of air movement with the cavity. This air movement can transfer heat from the party wall cavity to the outside, leading to far greater than predicted heat loss from the building.

The project went on to calculate the actual thermal performance of the party wall based on the excess heat loss and concluded that the U-value of the party wall was between 0.5 and 0.7 W/m2K. In a terraced house, where the area of party wall could be as large if not larger than the external wall, this represents a significant excess heat loss.

Further research then showed that by closing the party wall cavity with insulated cavity barriers, the effective U-value could be reduced to 0.2 W/m2K, and by fully filling the cavity with mineral wool insulation, the U-value was reduced down to 0 W/m2K, ie zero heat loss.

The revised SAP 2009 software includes Table 3.5 covering U-values for party walls based on this research. The table states that a solid party wall can assume a U-value of 0 W/m2K because there is no cavity to allow the movement of air. An unfilled open cavity will be assigned a U-value of 0.5 W/m2K, an unfilled cavity that is sealed against air infiltration will be assigned a U-value of 0.2 W/m2K and a fully filled and sealed cavity will assume a perfect 0 W/m2K.

More insulation in party walls So what does this mean for timber frame buildings? Currently timber frame party walls contain acoustic insulation in both leaves between the timber studs, and insulated cavity barriers around the perimeter of the party wall cavity. This should allow a U-value of 0.2 W/m2K to be assumed for the party walls, based on the criteria set out in SAP 2009. However, this is not a particularly desirable option, because it is still far worse than a perfect wall

The simplest solution to these potential problems will be to use unsheathed party walls or only sheathe one leaf. With open or partially open party walls, the insulation can be easily installed once the building is made weathertight. It is also possible to perform site checks. As with masonry cavity walls, if fully sheathed timber frame walls are used and the insulation installed during erection, subsequent checking and snagging would be very difficult.

Timber frame is ideally suited to buildings with repetitive layouts such as flats and care homes, so the new Part L requirements may bring some changes in detailing and order of work, but it will also bring valuable overall improvements that occupants will benefit from, not least valuable savings on fuel costs.

Because much of a timber frame building is constructed offsite on a clean, efficient and well-managed production line, the quality of the end product can be enviable. This helps on site by reducing material waste, simplifying and speeding construction methods, and delivering a building to the client that performs well against the new regulations. Using a truly sustainable material, offering high insulation values, quality construction and good air tightness, new timber frame buildings are well placed to meet the evolving needs of planet earth and its occupants.

Party walls unsheathed for ease of insulation

with no assumed heat loss. Therefore, it is likely that thermal insulation will need to be installed between the studs as well as in the cavity between the two leaves of the wall, allowing zero heat loss to be assumed.

Achieving this on site may require some changes to current practices.

Installation of the insulation between fully sheathed party walls during erection may slow the build progress, as additional time would be needed. Also, ensuring that the insulation remains dry and does not become dislodged during the rest of the build may be difficult.

Timber frame: modern and truly sustainable Dr Robert Hairstans, Head of the Centre for Off-site Construction & Innovative Structures at Edinburgh Napier University, outlines the advantages of off-site construction techniques with sustainability in mind Timber, in many respects, is the ideal construction material. It is strong in both tension and compression, it has a high strength to weight ratio and can be relatively easily worked. If appropriately sourced, timber can be considered truly sustainable. Primarily, however, man has used timber as a building material because it tends to be readily available in most habitable regions of the world.

The climate and conditions of each region have had a bearing on the nature and species of tree growing, which in turn have influenced the end form of construction. These too have evolved over time, through mechanisation, the invention of new timber products and different connection methods. Furthermore, modern market specifics such as procurement methods and local building regulation requirements have also influenced the finished building form.

location. Modern methods of construction (MMC) are about better products and processes. They aim to improve business efficiency, quality, customer satisfaction, environmental performance, sustainability and the predictability of delivery timescales. MMC, therefore, engages people to seek improvement, through better processes, in the delivery and performance of construction.

From production to construction Many of the improvements in manufacturing production systems can be adopted or adapted for off-site construction. These ‘borrowed’ lean production principles include: • Reducing non-value adding activities (eliminating waste) • Reducing the lead time (bringing projects on stream more quickly) • Reducing variability (improving quality) • Reducing complexity (making buildings easier to construct) • Increasing flexibility (adapting designs for different requirements) • Increasing transparency (making it easier to see how processes work).

Lean principles can also be applied during the on-site construction conversion process applying available tools and management techniques: • Last planner – a planning system that converts ‘should achieve’ thinking to ‘will achieve’ by enabling multi-trade collaboration to enhance project predictability and work flow • Visualisation – making construction processes transparent by communicating key information effectively • Daily huddle meetings – engaging the work force in lean construction via two-way communication in the workplace, which includes activities such as project progress discussion and tool box talks • 5S – a Japanese system for maintaining a clean and efficient workplace.

Industrialised processes require accurate and reliable information.

Therefore, modern information and communication technology (ICT) is essential for monitoring and improving production-focused construction processes. The requirements of total quality management (TQM) and business process engineering (BPE) are considered the key drivers behind the use of increased levels of ICT for key business functions.

An example of this is the use of Enterprise Resource Planning (ERP), regarded as one of the most innovative developments in ICT of the 1990s, as it implements best practice procedures, standardises business processes and systems and provides an ideal platform for transparency.

Despite its traditional roots, the timber industry is embracing technology to re-engineer timber for purposes beyond the limits of sawn timber. Timber composites overcome the dimensional limitations of sawn timber and improve performance, structural properties and stability, and transform the natural orthotropic product into one with more consistency. Composites also optimise the use of material and correspondingly minimise waste.

Re-engineering timber for sustainable construction Sustainability is a key theme of MMC and timber has advantages when considering environmental impact. Forests can provide an ‘income’ to meet our present needs whilst being ‘built’ to act as ‘capital’ for the next generation. Timber methods of construction are also more readily adaptable, allowing the building envelope performance to be improved through increased air-tightness, and reduced thermal conductivity and cold bridging.

The dominant form of timber construction in the UK is platform frame, a panelised system derived from balloon framing. Timber platform frame accounts for some 25% of new build housing construction and is normally externally clad with a masonry skin. The more modern methods of this form of construction have a higher level of finishing carried out off-site including the pre-installation of insulation, services and external lightweight cladding.

Many prefer the versatility of timber frame for panelised, volumetric and hybrid ‘built off-site’ systems. Other suitable formats include timber post and beam, and ‘massive’ construction using solid timber panels. The common thread making all these systems more efficient – and therefore more sustainable – is moving the bulk of the construction processes into well managed, factory conditions and performing minimum installation work on site.

Supporting Services TRADA Technology has several publications on timber building systems:

Examples of timber composites used extensively in structural applications are glue-laminated timber (glulam), laminated veneer timber (LVL), laminated strand lumber (LSL), parallel strand timber (PSL), crosslaminated timber (CL) and oriented strand board (OSB). Massive timber is pushing the boundaries of timber engineering with CL panels that enable rapid construction in timber high-rise, tested so far up to nine storeys.

Composite forms also see timber working in combination with other materials in order to improve performance: • Flitch beams – a timber-steel-timber sandwich configuration with enhanced strength and stiffness, which is particularly useful when depth and width of section is limited • Timber-concrete composites – utilised primarily for floor slabs to improve fire resistance and acoustic separation, as well as enhancing strength and stiffness performance and the thermal mass of the building envelope • Structural insulated panels – a form of wall and roof construction with increased insulation and reduced cold bridging, acting compositely to perform structurally.

Timber construction forms have evolved over the centuries and will continue to do so in order to meet future industry challenges. Facilitating this process is the new European Code of Practice for structural design (Eurocode 5 for timber), which is more transparent and provides more scope for deriving technical solutions and incorporation of innovative products.

Timber is therefore well placed to achieve the requirements of the future through the adoption of a MMC approach: suppliers become vendors, workers become team players and clients become partners within a continuous improvement cycle where applied research and development maintains an evolutionary process.

Volumetric building: idea to realisation David Jenkins, Director of the Welsh woodland management partnership Coed Cymru, describes a unique manufacturing system that maximises the use of indigenous UK timber components Ty Unnos translates into English as “House in one Night” and this is was the origin of many rural dwellings in Wales until the late 19th century. It was believed then that, if a house could be built on common land in one night and smoke rose from the chimney at dawn, then the freehold of the land belonged to that person who constructed the property on it.

In 2007 the name Ty Unnos, with its roots deep in Welsh folk history and associations with self reliance and making best use of local materials, was chosen to describe a collaborative research programme undertaken by a consortium of public private and academic partners.

The 21st Century Ty Unnos came about when the Countryside Council for Wales asked Coed Cymru to investigate how to produce affordable rural homes using homegrown softwood. Coed Cymru used its longestablished partnership with The Welsh School of Architecture and Bangor University to develop the project, funded by the Countryside Council for Wales, Wood Knowledge Wales, the Environment Agency and Powys County Council. Consultants Cowleytimberwork and Burroughs provided engineering expertise.

Coed Cymru started producing products with Welsh timber in 1990 and has successfully developed outdoor furniture, laminated flooring, windows, doors, cladding and wood chips for fuel, and now Ty Unnos.

After the initial study, they secured further investment from the Technology Strategy Board and new partners: Pontrilas Timber, Kenton Jones Ltd and Blaenau Gwent County Borough Council.

The Ty Unnos system, which is now being manufactured and marketed for affordable housing by the Oswestry company Elements Europe, has won a string of major awards for innovation including TRADA 75th Anniversary Award.

Renewable source Builders have traditionally preferred Scandinavian or Baltic timbers due to their stability in comparison to the locally sourced timber, which grows faster in the UK’s environmental conditions.

Spruce grows very quickly in the mild, wet Welsh climate and this produces timber of low density with a tendency to twist as it dries. These disadvantages can be overcome by compounding small sections into larger components that fit well with the need to provide wide voids for insulation.

The building system comprises a series of portal frames made from Welsh spruce beams. Secondary ladder beams span between these frames to form floor and ceiling joists and wall studs before pre-insulated infill panels with voids for windows and doors are attached.

Ty Unnos Modular Elements Europe saw the opportunity to develop Ty Unnos ModularTM, a volumetric housing system based on the original concept, using locally sourced materials and local labour wherever possible. The system is designed to reduce site, labour and waste costs whilst improving thermal performance.

So far, Elements Europe has developed 15 house types from onebedroom apartments to luxury four-bedroom homes, all made in a factory. The modular system is capable of providing accommodation up to three storeys, in various arrangements, to maximise site density.

Their layouts comply with various Registered Social Landlord spatial requirements, Welsh Assembly Government, Homes and Communities Agency and Lifetime Homes standards.

The unique configuration of structural components provides an internal wall cavity with the potential to be filled with a range of insulation materials – recycled paper is the environmentally preferred insulation – providing a wall U-value of 0.17 W/m2K and exceptional thermal performance levels. Allied to the thermal performance is an exceptional air-tightness standard, all helping to reduce carbon emissions.

This combination of thermal performance, air-tightness and a mechanical ventilation heat recovery system provides a residential solution that is exceptionally economical to run while maintaining a comfortable room temperature.

It has been inspiring to work with this very dynamic company to bring what was a very interesting research project to a commercial reality.

Designed primarily for the low-rise residential market, Ty Unnos ModularTM is set to radically change established house construction methods, by maximising the use of indigenous UK timber components uniquely manufactured to form the building superstructure.

The use of ‘home-grown’ timber in the structure of the Ty Unnos ModularTM system ensures that the carbon footprint is kept to a minimum.

Timber is procured from local forests with Forestry Stewardship Council approval to maintain a locally sourced product. It is graded, machine cut, kiln dried then treated and fabricated into structural components for assembly into a volumetric housing solution.

The UK has 1.6 million hectares of softwood plantations, producing some 9.8 million tonnes of timber annually. This plentiful supply ensures timber can be used in construction industry for the foreseeable future.

By enforcing a tree re-planting policy, stock can be maintained, allowing timber supply for Ty Unnos into perpetuity.

Sustainable technology The unique structure, and integrated supply-chain, epitomises ‘lean’ construction principles by addressing waste in a number of ways, primarily by components manufactured from a single standard timber component dimension. Off-cuts are fed back into the manufacturing process for re-work and integration into the next structural component.

Ty Unnos ModularTM achieves Code for Sustainable Homes (CSH) Level 4, which exceeds the standard required by the 2010 revision of Approved Document L for England and Wales. Code Levels 5 and 6 are attainable using additional bolt-on features.

Although finish quality and the energy performance are substantially improved, costs are still comparable with traditional construction methods. Cost is contained due to the abundant nature of the raw materials and efficient fabrication methods in its volumetric construction.

Realisation: the roll out In order to control the application of the technology, Ty Unnos ModularTM will be rolled out via a select number of developers within the UK residential market, strategically selected and located to satisfy the UK demand. These developers are selected according to their approach to the model, the technology, and above all their determination to help to provide sustainable affordable residential accommodation within the framework developed.

TRADA Technology is assisting Coed Cymru to obtain the European Technical Approval needed for this timber frame building kit to be offered to developers.

THE ONLY OAK FRAME SPECIALIST WITH BM TRADA Q-MARK CERTIFICATION For centuries, oak has been the heart and soul of Britain’s most beautiful buildings but under pressure from new building materials, the use of oak was under threat during the beginning of the 20th century.

Thankfully, English Heritage Buildings, now with the BM TRADA Q-Mark seal of approval, has led the way in reviving oak frame construction, ensuring the survival of a beautiful, sustainable building material and centuries-old carpentry skills.

From humble beginnings, English Heritage Buildings has grown to become the UK’s leading manufacturer of oak frame buildings and is now the first and only producer of oak frame building systems to achieve BM TRADA Q-Mark certification. The highly respected certification gives independent verification that English Heritage Buildings continues to provide a high quality product on a consistent basis and in a controlled manner. It covers both the systems and processes used within the company, as well as the quality of design, manufacture and construction of the buildings.

The BM TRADA Building Systems Q-Mark certification ensures that incoming materials and components are correctly specified and that processes are in place to control their purchase. The scheme also gives specifiers, regulators and inspection authorities the assurance that the product is fit for purpose and meets the requirements of the European guidelines for timber frame building kits (ETAG 007), as well as all relevant Building Regulations requirements within the UK. English Heritage Buildings uses only finest quality, green, unseasoned oak. The strength of the material allows for the construction of light-filled, open living spaces without the need for internal, load bearing walls and it is also a ‘green choice’. All of the timber comes from managed woodlands, where two or more trees are planted for every one felled and quality is assured at every stage of the building process.

English Heritage Buildings intimately understands its craft; how the timber is best shaped and orientated, how the wood is best joined together, and the wide variety of possibilities that green oak permits. Furthermore as part of the careful oak selection process, English Heritage Buildings employs graders trained and certified by BM TRADA in the science of grading oak for structural purposes.

Timber frame: low energy, high performance Author Geoffrey Pitts and advisory editor TRADA Technology’s Robin Lancashire introduce TRADA’s new book about best practices in site planning and building design to achieve energy efficiency

The external climatic conditions which influence energy consumption are the daily and average seasonal temperature (winter and/or summer), the daily and seasonal solar radiation, the winter and summer wind (speed and prevailing direction) and, to a lesser extent, the precipitation.

Energy efficiency in buildings comes at a cost. Energy is another word for fuel - most commonly electricity, gas, oil or solid (coal) fuel. All fuel costs money in some form and the more fuel that can be saved with energy efficient buildings, the lower the running costs for building users and owners.

Internally, air temperature is the major internal environmental factor which affects energy consumption as the building heat loss is directly proportional to the inside/outside temperature difference. While the internal comfort air temperature may vary between 15°C and 30°C, this will normally be between 18°C to 22°C during the heating season.

There are four key indices which determine the comfort of occupants in buildings: thermal, air movement, ventilation & relative humidity.

Climate type The climate type under consideration can be broadly described as cool temperate, where winter heat loss is the major energy efficiency design criterion. Within the general cool temperate climate, a number of variations occur. In terms of macro-climate there are the cold dry winters and hot dry summers typical of inland continental areas (north central USA, central Canada and inland northern and central Europe) and cool wet winters with moderate, humid summers typical of maritime regions (UK, Ireland, Denmark, Netherlands Belgium and Atlantic coastal France). In terms of micro-climate, there are variations caused by local topography and vegetation or existing buildings. All these variations must be considered in the design to reduce energy consumption.

Planning Site planning decisions are taken early in the design process and have a significant effect on overall energy efficiency. Orientation is closely linked to all other site planning decisions.

One of the particular benefits of energy-efficient planning is that there is little or no cost penalty associated with the decisions, while the potential energy benefits can be high. For a given residential building density there are few additional costs for efficient layout and southerly orientation, and landscaping costs are typically low in relation to overall development costs.

50

The Timber Industry Yearbook 2011 Timber Research And Development Association www.trada.co.uk

Section Heading.

Timber frame

The energy considerations for site layout are orientation, minimum overshading and wind protection. Other site considerations are view, privacy, minimum roadworks (length, width and specification) and minimal service runs and the relationship of landscaping and gardens to the buildings. While these considerations can affect the energy decisions, they would not normally be expected to compromise them. The target site density, however, might be expected to affect energy efficiency decisions adversely, but at even high density (say up to 200 persons per hectare) good orientation with minimum over-shading for passive solar gain can be achieved with careful layout and grouping. There is another issue associated with site density: high density implies a greater number of shared party elements, which reduces fabric heat loss that might offset reduced passive solar gains.

Building envelope It is the building envelope that utilises and/or controls the natural elements to assist in providing economic thermal comfort. For cool temperate climates some level of additional space heating will be required but, in most cases, mechanical cooling will not be necessary.

The building envelope decisions which affect the ‘economic comfort’ requirement are the thermal resistance, thermal mass and thermal response of the roof, walls and floor, and the thermal performance, natural lighting and ventilation characteristics of the windows and doors. These decisions are the major influences on the overall level of building heat loss, on the amount of solar energy collected and on the usefulness of this energy, that is on the space heating requirement. They also influence the level of direct power consumption for lighting and appliances.

Adding a convenient 50mm service zone to a conventional 140mm stud wall increases the insulation depth to 190mm

And it is in the building envelope where the particular energy saving advantages of timber frame construction can be found. Frequently, the decision to build in timber frame is taken for reasons other than energy efficiency; for example, speed of erection, reduced site labour, dry construction, precision and accuracy of finished building or even cost. However, as energy efficiency continually becomes more and more important to clients and designers, this will become one of the major reasons for choosing timber frame simply because the system has the ability to incorporate very high levels of thermal insulation.

Thermal insulation is not the only energy criterion, however, and a view which is often expressed is that the low thermal mass of a timber frame fabric is such that solar gain cannot be effectively utilised. However, high thermal mass is not necessarily beneficial; but rather, the important factor is the provision of the right level of thermal mass in the right place to utilise solar gain. This can be achieved in timber frame without compromising the structural integrity of the system.

Designers need to consider all of these potentially conflicting issues for optimum energy efficiency, but with buildings responsible for up to half the total national energy consumption in industrialised countries, surely that extra work at the drawing board is more than justified.

Low carbon: how does timber fit the bill?

TRADA Technology research officer Miles Brown argues that timber can play a significant role in helping the construction industry reach its energy target

Figure 1 Estimated percentage of GHG emissions for different stages in the construction life cycle

The UK Government has ambitious plans to transform the energy efficiency of construction, acknowledging the oft-quoted words of Norway’s Gro Harlem Brundtland, that “sustainable development is that which meets the needs of the present without compromising the ability of future generations to meet their own needs”.

Residential homes alone account for nearly one-third of the UK’s carbon emissions, so the construction sector is right at the heart of Government strategy. Sustainability is the single most important future trend in the construction industry.

The 2008 Climate Change Act is an important tool. It creates a new approach to managing and responding to climate change in the UK, by setting legally binding targets to reduce greenhouse gas (GHG) emissions (compared with 1990 levels) by 34% by 2020 and by 80% by 2050.

The Low Carbon Transition Plan was rolled out in 2009 as a route map to achieving the 2020 target. The wide-ranging plans have significant implications for the construction sector.

Residential buildings • 2020 – heating emissions to be down 29% compared with 2008 • 2016 – all homes to be zero carbon • a major retrofit to increase the efficiency of existing stock.

Non-residential buildings • 2020 – emissions to fall by 13% compared with 2008 • 2019 – private sector buildings to be zero carbon • 2018 – public sector buildings to be zero carbon.

An innovation and growth team drawn from the construction sector and from the Government, operating under the Department for Business Innovation & Skills, estimates that for UK construction by far the greatest part of GHG emissions associated with a building’s life cycle occur as a result of occupation and use (83.5%), followed by the manufacture of the building components (13%) (Figure 1).

The message is clear: energy emissions associated with building use must come down, but so too must the emissions associated with producing the components used in construction.

Timber has unique properties compared with other materials. Through photosynthesis, trees trap large amounts of carbon dioxide, store it as wood and release oxygen. Every cubic metre of sustainably produced timber used instead of other typical building materials reduces CO2 emissions. Timber can therefore contribute hugely to the reduction of GHG emissions, both from the construction phase of a building and during its service life.

Figure 3 Wood fuel, a source of low-carbon heating

Low thermal conductivity As timber does not tend to transmit heat, it is an efficient thermal barrier; hence timber window frames and timber studwork ensure that a building remains well insulated. In addition, wood fibres make efficient insulation products in their own right, both as insulation boards and insulation batts.

The insulation qualities of timber means that less energy is required for space heating, and so timber can assist in reducing GHG emissions from fossil fuels.

Low-carbon heating If grown sustainably, woody biomass can be a source of low-carbon heating, either in the form of traditional logs, or increasingly as pellets in more sophisticated boilers. When combustion takes place the CO2 in timber is released. However, if new growth is planted to replace it, CO2 becomes reabsorbed (Figure 3). The only emissions to accumulate in the atmosphere are those associated with processing and transport. This is in contrast to fossil fuels, where all of the CO2 released from combustion accumulates in the atmosphere.

During the process of photosynthesis, CO2 from the atmosphere is combined with water which is absorbed via the roots. The carbon from the CO2 is incorporated or sequestered into carbohydrates which form the fabric of the tree. Wood is made from approximately 50% carbon and every tonne of wood that grows absorbs the carbon from approximately 1.8 tonnes of atmospheric CO2. The carbon will remain sequestered until the wood is burned or decays, when it re-combines with oxygen to release the CO2 back to the atmosphere.

Sequestration is not a permanent solution to the absorption of CO2 from the atmosphere, because in time the CO2 will be re-released. However, use of wood in construction provides a reservoir of stored carbon; so the longer the wood is in service, the longer the atmospheric CO2 remains sequestered. It is estimated that in 2009 timber in the UK housing stock held 19 million tonnes of absorbed carbon (representing nearly 70 million tonnes of CO2) and has potential to increase to 29 million tonnes of carbon by 2019.

Embodied carbon To bring a building material to site will require an investment in energy for extraction, processing, manufacture and distribution. Much of this energy will have been derived from fossil fuels, so all construction and other products will be responsible for the release of GHG before they are incorporated into a building. In the interest of these emissions, consideration should be given to the materials used. The University of Bath has collected data on embodied carbon and energy for a comprehensive range of construction materials, and the findings have

been published as their Inventory of Carbon and Energy (ICE). Ramboll, a leading structural engineering organisation, has applied the ICE figures to similar sized buildings constructed from different materials. The results indicate that a timber-based construction contains considerably less embodied carbon than one built from competing materials (Figure 4). If carbon sequestration is counted, the embodied carbon of the building falls below zero.

End of life options At the end of its service life there are various options that can avoid disposal and the immediate release of the sequestered carbon. It is often possible to reuse or recycle wood. Over a million tonnes per year of recycled wood is used in the UK to manufacture chipboard, for example, offering the potential for the carbon to remain sequestered in a further construction project.

The market for biomass fuel is growing rapidly in the UK. Electricity generated using recycled wood is eligible to contribute towards the UK’s renewable energy targets. Burnt wood will inevitably release its sequestered carbon as CO2 back to the atmosphere.

However, much of this near carbonneutral energy can replace highly carbon-intensive fossil fuels.

Timber frame walls – sound performance Chiltern Dynamics’ technical coordinator, Barry Cope, comments on why timber frame walls can offer excellent acoustic test results Based on Chiltern Dynamics’ sound insulation test results last year, timber frame party walls are exceeding Approved Document E requirements more than 95% of the time, while nine out of ten timber frame walls achieved more than 50 dBDntw + Ctr, 5dB better than legislation requires. This can be used to gain valuable Code for Sustainable Homes credits.

The following seeks to explain why timber frame construction is able to achieve good sound insulation performance.

Testing frequencies Sound insulation is tested across a range of frequencies that can be heard by the human ear. It is good practice however to measure beyond the range of human hearing. To achieve good overall sound insulation performance, it is important to perform well across all of the frequencies.

Measurements are taken in third octave bands, which show and give data broken down into separate frequencies. This means we are able to distinguish between low frequencies (base), mid frequencies (typically voice) and high frequencies (high pitch whistling).

Testing When conducting an airborne sound test, a speaker is placed in the ‘source room’ (the room that will be used for the loudspeaker) and pink noise (like the noise from an untuned TV, but controlled) is played out, at around 100 Decibels, depending on room conditions. The exact noise is measured in the source room and then measured in the ‘receive room’ (the room on the other side of the wall being tested). In simple terms, the noise in the source room, minus the noise in the receive room equals the sound insulation performance of the wall.

The resulting measured figures are displayed on a graph.

The lighter line represents the measured sound pressure level. The darker line represents the sound reference curve, which is used to calculate the final sound insulation figure. This is done by adding up the measured figures below the reference curve until they reach 32dB. The reference curve will be moved up and down until the sum of all figures lower than the reference curve is as close to 32dB as possible.

Timber frame walls perform well across the majority of spectrum.

Typically, lower performance is concentrated into the lower frequency bands so measurements below the reference curve are typically taken from the lowest three octave bands. This means the position of the reference curve is high in comparison to the measure figures and the final sound insulation test result therefore is also good.

Acoustics

Panel stiffness Timber frame performs well because of a number of factors. Part of the performance is affected by panel stiffness. Within timber frame, the first part of the construction is a combination of the plasterboard and plank which is dense and strong but flexible enough not to pass all of the sound energy into the core structure of the wall.

Transmission and damping Another factor is the damping of sound. It is linked closely with panel stiffness. Damping of sound is where the sound that is transmitted cannot continue through the structure, much in the way the suspension on a vehicle works, but on a much smaller scale.

65

The following is a list of preparations that need to take place before the acoustic testing can be carried out and will ultimately affect the performance of the wall: • Windows are fitted without any gaps around the windows and trickle vents are fitted.

• Internal and external doors are fitted – internal doors will allow an increase in sound pressure and give a more accurate result; external doors will stop sound travelling out of the building and into the plot being measured.

• Socket covers are fitted and skirting boards are in place.

• Quiet conditions – the sound level meter used is only a machine and cannot differentiate between site noise and noise that is being measured as part of the sound test.

Void depth and mass One of the most important factors is a combination of void depth and mass in the party wall. A larger void and greater, isolated mass will both improve the sound insulation. Common Robust Detail EWT-1 (which is typically made up of 2x100mm studs with a 40mm gap, a layer of plasterboard and gypsum plank on each room face and a minimum of 2x60mm sound absorbing insulation within the cavity) has a large void between the structural materials. The void benefits the wall, meaning when the sound energy impacts the plasterboard wall linings, the resonant frequency of the cavity is sufficiently low that it is not measured on the standard sound insulation test. As mentioned before, the low frequencies that travel through are not within the human range of hearing.

Timber frame construction can attribute its good performance down to a combination of materials being put together in the right way. The balance of materials, voids and joints combine in a way that can give a high performance.

Sound absorption Higher frequencies are a lot more complicated exhibiting increases and decreases in sound pressure level, which causes vibrations that are passed on through the wall. Within timber frame, these are partially stopped with the insulation in the wall, which not only acts to avoid heat loss but absorbs higher frequency sound that resonates within the cavity by turning the sound energy into heat energy.

Barry Cope says to achieve good overall sound insulation performance, it is important to perform well across all of the frequencies.

Timber frame is not without its problems, albeit they are rare. If foundations are not built exactly to specification, the resulting foundations can be too small. The result of which means the timber frame party wall cavities will not be wide enough. Resonance within the cavities will therefore occur at a slightly higher frequency and become measurable during the sound insulation test, reducing the overall performance of the wall.

Cladding

Case study of cladding at Stonebridge Hillside Hub, West London: TRADA Technology’s marketing manager, Rupert Scott, describes the use of the softwood larch as cladding in this extract from a detailed case study published in 2010 The Stonebridge Hillside Hub is a key scheme in the continuing regeneration of the Stonebridge Estate in West London. It is a major resource for the 4,000 strong culturally diverse local community; it aims to bring people together, improve local health, enable educational, leisure and community initiatives, encourage investment in the local housing market, provide much-needed retail space and give a new focus to a previously deprived part of the borough.

Building description The building is formed of two six-storey wings joined by a three-storey community centre – a strongly articulated central building with a curved zinc roof and a private landscaped garden at the rear. The lower three storeys of the west wing contain a Primary Care Trust health centre. The lower two storeys of the east wing house a convenience store with a twostorey car park at the rear. The four upper floors of both wings contain a tenure blind mix of shared ownership and privately owned apartments.

External timber cladding The larch cladding was designed to achieve three scales of grain: • Firstly, Siberian larch was specified for its tight, uniform grain.

Sapwood was excluded and the untreated wood should weather to a consistent silver grey.

• Secondly, the elevation was separated into bands of horizontal boards separated from each other by zones containing vertically fixed boards and windows. The horizontal timbers run around the cantilevered balconies wrapping them into the composition and the overall effect is of large-scale vertical and horizontal grains woven together.

• Thirdly, two differing sizes of horizontal cladding board were used.

Again, this gives the façade a textured ‘corduroy’ feel of light and shade when viewed from the surrounding streets. Both board types

have thirty degree chamfered tops and bases to aid shedding of water and to prevent staining and warping. The boards are fixed with a gap between them small enough to prevent water ingress but large enough to allow air to circulate around the timber. A subtle detail occurs when the horizontal timbers wrap around the balconies where the thinner boards are omitted to allow a greater degree of transparency to these outdoor living areas.

The project was procured under a design and build contract with the contractor having a significant influence on specification. A typical result of this is to be seen in the apartment windows that have a very high performance specification but are aesthetically disappointing, in this case because of the very chunky frames. This shortcoming resulted in a particular timber detail being formulated where the vertical and horizontal boards sit in front of the windows, overlapping the thick frames so that, looking at the building, an elegant juxtaposition of glass against timber is seen.

The timber envelope achieves a U-value in excess of 20% above Building Regulations and all timber is from FSC certified sources.

The Stonebridge Hillside Hub uses softwood cladding. What if tropical hardwood cladding were specified? In this extract from TRADA Technology’s book External timber cladding, senior consultant architect Patrick Hislop outlines what to consider when using tropical hardwoods as cladding.

In the past, there has been a wide range of tropical hardwoods used for timber cladding, although less frequently used than softwood and generally limited to more prestigious buildings. Concern about the sustainability of many of these has limited their use. However, there are now tropical timbers being imported with full certification of sustainable management whether plantation grown or ‘secondary’ species. These secondary species are less well known but have similar characteristics of durability, strength and hardness as the better-known timbers. Some of the traditional tropical hardwoods may be grown in plantations that are not in their indigenous countries that may affect some of their basic properties of density, colour and durability. Confirmation may need to be sought that they are still suitable when used for cladding.

As it is not possible to include a full range of tropical hardwoods that are suitable for cladding, it is necessary to generalise on the typical features relevant to their use. Generally, tropical hardwoods are stronger, more robust and more durable than softwoods and may be a preferable choice if there is a high risk of mechanical damage.

Because of their density, they are less absorbent and will react more slowly to any variations in moisture but it is still preferable to use a species referred to as a small or medium movement wood. Tropical woods are usually supplied kiln dried rather than “green”. While many tropical timbers are rated as durable or very durable, this only applies to the heartwood and all sapwood should be excluded. Most tropical hardwoods are highly resistant to any treatment with preservative.

Further information on this is given in BS EN 350-2 and in the TRADA Wood Information Sheet, Timbers their properties and uses.

All the tropical hardwoods, whatever their original colour, will eventually weather to grey when exposed unfinished, although some will darken initially. While tropical hardwoods can be satisfactorily finished with coatings, care must be taken with the oilier woods, such as iroko and teak. It is likely that coatings on hardwoods may require more frequent maintenance than when used on softwoods, as they do not absorb penetrating stains as readily. If the bleached colour is acceptable, they are better left unfinished and should not then require any maintenance for the lifetime of the building. Other than bleaching out the natural colour, exposure to ultraviolet light will not significantly affect the surface of these hardwoods but the increased uptake or loss of moisture in unfinished wood can lead to some surface checking.

Because these woods are denser and stronger than softwoods, thinner sections can be used and tongued or rebated profiles are less likely to be damaged during construction or in use.

The layer of thinner horizontal boards are omitted at balconies to increase transparency

Fire doors: seeing the end game Mark Cummings, deputy technical manager of Chiltern International Fire, discusses the role of fire testing in the overall design of a building Understanding the logistics of how components come together to make an end product, whether it’s a fire-rated doorset or a finished building, is an important part of fire resistance testing. Contrary to popular perception, testing is not solely an end in itself and the test process could contribute so much more if the project team were to consider fire testing as integral to the whole build process, almost a ‘necessary evil’.

Firefighters tackle a blaze in a heritage building

Building owners and developers are often faced with a legal requirement to ensure products such as partitions, ceilings, fire curtains, penetration seals, glazing and fire retardant coatings will resist the passage of fire and/or control its spread. Fire performance for individual construction products is proven through destructive fire testing and assessment, while their required location and level of fire performance is determined by legislation, codes of practice or the accepting authority.

Testing and fire safety Fire testing of individual products is and will remain absolutely essential. We as a company have welcomed a change in mindset among manufacturers and others who are looking beyond the narrow parameters of a prescriptive fire test for more all-encompassing evidence of product performance. Increasingly, it is no longer satisfactory for a fire door simply to work at building handover. It needs to come with evidence that it will continue to perform well into the warranty period of the building and beyond.

There are a number of reasons for this, but for project managers one of the most important is the way the Regulatory Reform (Fire Safety) Order 2005 (RRFSO) has changed quite significantly the approach to fire safety in buildings since it came into effect four years ago. Now, all premises must have a Fire Risk Assessment (FRA) encompassing all aspects of fire safety within a building, carried out by a designated responsible person. It will report back any significant findings and it will be the duty of the responsible person to ensure that the findings are acted on and implemented. However, it will not detail exactly how to mitigate any particular perceived risk or problem with respect to substandard active and passive fire protection measures.

It is our observation that the frequency of which the question “does this provide satisfactory protection in the event of a fire?” is asked has increased dramatically. Products are generally tested in a certain number of configurations in order to cover as many of the expected end uses as possible, but inevitably not everything can be covered. In the past, it was generally our experience that specifiers and controlling authorities were often prepared to accept ‘best match’ evidence.

However, increasingly, this is not the case. As the complexity of the problem grows then manufacturers and installers more frequently have to step outside the bounds of their direct test evidence and use their products in non-standard applications.

Demonstration of double fire door testing

Additional evidence is increasingly required

Changes on site

One of the areas of fire protection where this will often occur is in the field of fire stopping and fire sealing around penetration seals.

It is rare to see a site configuration of service penetrations that has comprehensive, equivalent test evidence. There is a growing trend among regulating authorities to ask for additional evidence to support the application. If the trends we have seen continue, this will commonly mean specialised tests will be set up to replicate site conditions.

Another misconception that we as an industry have to address is the expectation that fire protection products can simply be bought off the shelf when you’re ready to install them. That might work in some instances, but architects in this country are more likely to require doorsets to be adapted to fit the design of the building.

Before embarking on product testing, therefore, it is important to look at the bigger picture. We have to see beyond the fire-resistance performance of the individual product, to test how it will work in conjunction with other components and above all how it will behave in situ. Fire resistance testing should not be carried out almost as an afterthought during a build project – it needs to take place early enough to ensure that fire protection products and systems are able to work efficiently.

To make the design work in practice, it often falls to the contractor to make changes on site, when problems come to light that the architect could not have envisaged at concept stage. Sometimes this will impact on the fire prevention systems and in extreme cases can lead to missed deadlines and swingeing penalty clauses.

From our point of view as a test body, therefore, it is only once the wider picture has been sketched in, can we assist in offering a test programme the client actually needs, at a stage in the project that is most beneficial to all concerned.

The customer is king Project manager Ian Makins of Hazlin of Ludlow Ltd talks about weathering the recession, market trends and the importance of an all encompassing Global Assessment for its fire doors and doorsets Hazlin products have found their way into a wide range of projects, including quality domestic residences, schools, hospitals, major financial institutions and many other prestigious projects, such as The Queens Gallery, The Royal Society and the John Radcliffe Hospital. Our clients ask for many variations and configurations of the fire doors and door sets we manufacture.

We work exceptionally hard to meet the needs of our customers and this has enabled us to weather the recession better perhaps than some others.

It has been harder work, more challenging, to win business. The market was, and still is, extremely price sensitive.

Hazlin aims to differentiate itself from competitors in other ways too.

We are able to offer BM TRADA Q-Mark certification for our fire doors and where required BM TRADA-Trak, FSC and PEFC chain of custody certification, something for which demand is definitely growing. Above all, over the years, drawing on our own test evidence and evidence supplied by door blank, glass and hardware manufacturers, we have built up a wide-ranging Global Assessment for fire doorsets which enables us to tender for most projects.

Even with this huge flexibility, clients can specify specialist products that fall outside the scope of the Global Assessment. In those cases, we will approach a test and consultancy body like Chiltern International Fire who will carry out further assessments and discuss the options with us. Often there is a simple compromise to be made, such as supplying a 54mm instead of a 45mm door or changing the glazing configuration. Very occasionally it might be necessary to run a full-scale fire test.

More and more nowadays, clients want fire doors which perform additional functions. Clients for example are asking for a very high level of acoustic performance, often in excess of 35 Rw dB. I am at pains to understand why acoustic performance is being set so high, higher perhaps than necessary. This may be because there is no guidance for higher values within regulations. Whatever the reason, following an extensive acoustic test programme, we can now supply single, double, glazed and flush doors doors that can achieve: • 36 – 38Rw dB (Building Bulletin 93 requires 35 Rw dB in schools for music rooms and assembly rooms) but which at 44mm thick are no heavier than normal solid core doors • Up to 46Rw dB with other core types.

The next step will be to submit these doors for fire testing at Chiltern International Fire, as part of our ongoing product development.

Flooring

77

Don’t shoot yourself in the foot with a silver bullet TRADA’s flooring expert Peter Kaczmar discusses the pros and cons of modified wood products for flooring The use of new, modified timber products as alternatives to natural wood floor coverings is growing, if recent trends are anything to go by. However, these alternative substrates have penetrated the flooring market only relatively slowly, as manufacturers have worked to overcome the natural scepticism shown by long-standing users of solid wood in the face of innovation. Nevertheless, these alternatives – products such as Accoya®, Kebony®, Indura Wood, VECOwood®, LigniaTM, Lunawood®, FloTermo© and Thermowood® – are starting to take root, to the point where they are being considered for even large flooring installations. But what are they and what are their benefits over unmodified wood?

The term ‘modified’ in this context means that the natural wood has been treated with a chemical, biological or physical agent to enhance its performance. It excludes wood treated with wood preservatives.

There are three main types of wood modification process: chemical modification, impregnation treatment and thermal modification.

Accoya® can be used for decking

Chemical modification Chemical modification involves the impregnation of permeable species of wood with chemicals. These react with water-binding sites present in the wood cell wall with the result that the wood becomes much more stable and resistant to distortion. Of the modified woods which can be used in the flooring sector, Accoya® is the main example where the chemical process (known as acetylation) produces a hard, resilient and stable material from a softwood species with virtually no cupping. The main drawbacks are the slight smell of vinegar and the limited species and colour choice (the process can only be used on permeable wood species).

Hardness values for Accoya® are similar to those of mahogany, black cherry or African walnut, wood species often used for flooring.

Similarly, furfurylation (impregnation with furfuryl alcohol) by the Kebony® process has little influence on wood strength properties.

Hardness was shown to be increased with level of substitution with Kebony® significantly harder than unmodified wood of the same species.

Hardness levels attained are significantly higher than for other wood species used in flooring and furniture applications such as maple.

Impregnation modification Impregnation treatments are responsible for products such as VECOwood®, LigniaTM and Indura Wood which can all be used for flooring installations. The VECOwood®, Fibre7 and Osmose Indurite processes impregnate wood with chemicals fine enough to fully penetrate dry wood when applied under pressure. These compounds polymerise (bind together) and fill voids normally filled with air in dry wood, increasing wood density and hardness.

In addition, dyes may be added in both processes, which change the colour of the wood throughout its section. This can be used to enhance the aesthetics of softwoods and permits repeated sanding without loss of colour. Again, species that are normally permeable are selected to enable modification to occur throughout the section. The main in-service benefits of the impregnation processes is that they improve surface hardness and dimensional stability.

79

A number of these modification processes may change or enhance the appearance of wood. Thermal modification darkens lighter coloured woods and different shades can be achieved with different thermal regimes. The colour extends throughout the wood section, which is desirable for flooring where maintenance including sanding is anticipated. Similar benefits can be obtained with the impregnation processes where pigments may be added specially to enhance or change the appearance of products such as with Vecowood® and Indura Wood.

Specifying for appropriate uses As with most products, it is important to exercise some caution when specifying modified wood substrates for specific situations given that some may have attendant disadvantages that may be overlooked. For example, the use of thermally treated woods for flooring should be carefully considered, bearing in mind that in certain species of thermally treated products, there may be a tendency for the surface to become softer and less capable of withstanding high levels of trafficking. There may also be a tendency for some reduction in splitting resistance and glue performance, which may influence the type of installation that is proposed.

LigniaTM makes an attractive floor

Thermal modification ThermalIy modified woods such as Thermowood®, FloTermo© and Lunawood® are produced by heating the wood to temperatures of 160-230ºC for several hours to several days. Heating wood to these temperatures and holding the temperature for these periods alters the chemistries of a number of structural and non-structural polymers that make up wood, thus changing its properties. This can mean an increase in dimensional stability, although in many thermal modification processes there is a reduction in the amounts of some structural polymers, resulting in a reduction in density, strength and surface hardness.

Supporting Services TRADA Technology’s Technical consultancy (Materials Division) offers an investigative and diagnostic service for all aspects of wood, including on-site problems arising from inappropriate use. Visit www.trada.co.uk or telephone the advisory line 01494 569601.

On the other hand, the use of modified woods as floor coverings has much to offer in terms of improvements in dimensional stability and resistance to distortion. This may allow for greater flexibility in terms of the dimensions of board or plank widths used in specific circumstances. Improved hardness achieved with some forms of modification may also extend the range of circumstances in which species otherwise considered unsuitable for use in heavily trafficked environments may be used.

There is no doubt that these product innovations offer greater flexibility within the wood flooring sector to extend the use and improve the overall perception of wood as a floor covering. However, specifiers must take care not to shoot themselves in the foot by using this innovation as a ‘silver bullet’ to solve all installation problems. Modified woods can improve on the natural product in many ways, but like wood itself they do not offer a ‘one size fits all’ solution. They must be weighed up on their individual merits when selecting for specific contracts.

Long span structures

Glulam leads eco-store race Chris Hopkinson, design manager at B&K Structures, sees a bright future for timber in longspan structures, particularly for glulam With the increased focus on sustainability and the environment very much on the radar, it is only natural that clients will look at building structures with far greater ‘green credentials’ than those currently being constructed for large scale retail stores.

For many years steel has been the primary building material used for structural frames of long span retail structures in the UK. This approach, however, has not been the case across much of continental Europe. In recent years, these traditional designs have begun to give way to the more eco-friendly concept of using engineered timber in the form of glued laminated timber (glulam).

Why timber has gained favour In the past, many assumed that timber members would be unable to span the required distances. Specifying timber would therefore result in unwelcome compromises in store layout, it was believed.

Recent experience, however, has demonstrated that such assumptions are incorrect. The new breed of eco-store is proving to be an environmentally and aesthetically pleasing alternative to the more industrial and energy-hungry steel stores of yesteryear.

In recent years, Tesco, Sainsbury’s and Asda have all constructed eco-stores, while Waitrose, Lidl, and Marks and Spencer have started to develop eco-stores for the near future. Since its first eco-store in Cheetham Hill, Manchester, the number of eco-stores constructed by Tesco is now well into double figures, with many more stores to rollout over the coming months.

Sainsbury’s flagship eco-store at Dartmouth

warmth to a structure. Also, where a steel or concrete frame would normally have the additional expense of having to be hidden from view, timber frames are often intentionally left visible.

Another key driver is that of cost. Glulam structures in the UK are subject to market forces, which dictate the price of raw materials, (timber), however, they are also subject to currency fluctuations between the Euro and pound sterling. As much of the engineered timber used in large projects is imported, a strong pound makes the cost more attractive. A strong Euro, conversely, makes fabrication and erection by experienced UK firms more cost effective, even if the engineered timber is imported.

Fire Glulam’s main environmental advantage over steel and concrete is that it requires much less energy to produce, is sustainable, renewable and is a biodegradable material. In the long term, decommissioned structures can be dismantled and rebuilt elsewhere or can be used as raw material to produce energy.

Timber has an inherent natural beauty that steel and concrete cannot compete with, and is often specified to provide a feel of quality and

One initial concern of those unfamiliar with the performance of timber structures is how they perform in a fire. However, the fire resistance qualities of glulam are excellent compared to those of other unprotected non-combustible materials. When subject to fire the outer faces of the glulam char at a predictable rate and this charring acts as a thermal insulator, protecting the inner timber. As long as the timber is correctly sized, specific fire ratings can be achieved without the requirement for any additional protective treatment.

Long span structures

Durability A further concern often voiced is that of durability, yet, so long as they are maintained correctly, glulam structures are highly durable.

The adhesives used in the production of glulam have been proven to be stable in the long term, while the timber itself suffers no adverse effects if kept dry. Typically, internal glulam tends to be manufactured from whitewood spruce while the more inherently durable larch is sometimes used in external situations. By use of careful detailing issues of durability can be avoided.

Where glulam is to be used internally the only protective treatment required is a clear breathable finish intended to simply prevent mud stains occurring during construction. This is applied during manufacture as a standard procedure. When used externally, additional protective attention may be required, depending on the detailing and exposure to the elements. For example, the external columns to the front of Sainsbury’s new eco-store at Dartmouth utilises glulam formed from larch. These columns, with the standard clear treatment applied, needed no further protective measures.

Sustainability

The specialist process used to manufacture glulam members ensures that virtually any structural forms can be achieved (limitations of member sizes are based on transport restrictions rather than limitations of manufacture).

Single members spanning 40m have been produced, though something more in the region of 18m is the norm for a standard retail store.

A hybrid bowstring truss offers several advantages, not least the reduction in depth of the glulam roof support member that forms the top boom. Visual impact is reduced even further by the small diameter of the steel bowstring tie rods.

Curved or arched members are easy to produce and can provide the additional visual impact that architects may be seeking to achieve.

Typical examples of this can be seen at Sainsbury’s new flagship eco-store at Dartmouth, and hybrid design of the four span 12,000m2 arched structure at West Ham that forms the largest bus garage in Europe and is to be used for the Olympic transport infrastructure.

Using installation companies with full chain of custody, who are accredited by schemes such as the Programme for the Endorsement of Forest Certification (PEFC) and Forest Stewardship Council (FSC), will ensure that all timber used is sourced from legal and sustainable sources.

For example, when a hidden connection is required with all steel plates set within the timber member and bolts/dowels recessed and plugged, the member size may need to be increased to accommodate this. However, smaller members can often be used where plates or bolts can be visible.

Construction It is often, though not always, the case that roof bracing and vertical bracing is formed in steel. This is so that slender members can be incorporated into the timber frame. Vertical bracing to the sales floor areas of stores are made from architecturally attractive tie rods.

Although the back of house can be constructed in engineered timber, steel is usually the favoured option. This is because the back of house is often subject to large plant loadings and a steel structure helps to obtain a shallower structural zone. In addition, this is somewhere that can take advantage of less expensive steel and thus ensure that the overall cost of the hybrid eco-store is reduced.

Structural forms A variety of structural forms are possible to provide the large spans typically required for a retail store. These include solid glulam rafters, hybrid bowstring trusses, varying depth members, curved members and arches.

It is important to prevent the bases of the glulam columns from being in direct contact with freestanding water during construction and therefore the base of each glulam column is seated on a specially designed steel stub. Other than preventing the glulam column from sitting in water, the stub allows the columns to be lined and levelled in exactly the same way as would be done for a steel column.

Hybrid structures typically consist of glulam forming the entrance canopy and main sales floor with steel members forming the roof and vertical bracing. Steel is also often used to form the back of house. The engineered timber provides a low carbon structure while the structural steelwork is utilised in areas of high load.

In order to limit the number of internal columns, a typical grid layout of a retail store is 18m x 12m, which has been successfully achieved using both timber and timber hybrid designs. Both the Sainsbury store at Dartmouth and the Tesco Store at Tramore utilised solid glulam roof beams to support the roof, while Tesco’s latest eco-stores adopt a timber and steel hybrid bowstring truss design.

Connections used for timber structures can vary greatly and are usually dictated by the aesthetic requirements specific to the structure in question. Some architects like the ‘honesty’ of visual plates and bolts while for other schemes a virtually hidden connection is required. Each structure is considered on its own individual merits and the aesthetics are balanced with the economics to achieve a solution acceptable to all.

Steel plates and bolts/dowels are utilised to achieve the required degree of load transfer in large-scale timber structures. Connections in timber structures are often the critical part of the design. It is often a balance between what is needed to transfer the loads and what is visually acceptable.

Hybrid structures Though it is possible to construct retail stores as solely timber structures, an excellent alternative, which takes account of the properties of different materials, is the use of a hybrid timber and steel structure. This type of store combines materials to achieve the optimum balance of aesthetics, sustainability, strength and cost. A perfect example of mixing different materials to obtain the optimum solution is Tesco’s eco-store in Ramsey, Cambridgeshire, claimed to be the world’s first ‘zero-carbon’ store.

Connections

With modern design and production techniques a steel and timber hybrid store can be detailed as one complete model, fully incorporating both materials. This ensures that there is not an issue with steel detailed in one package not correctly relating to timber detailed in another package. As such, all members and connections can be fully modelled in 3D and the fabrication files directly downloaded to CNC manufacturing lines. This system removes the ‘human error’ factor and ensures that timber is cut, drilled, shaped, rebated etc exactly as required.

One of the key requirements of timber framed stores is that they must compete with the build time of steel framed stores. Due to the sub assembly undertaken before members are erected, construction time of a timber framed store is on a par with that of comparable steel framed design. In the retail world, time is very much money, and it is essential therefore that stores can be quickly constructed and opened for business on time.

Recent Developments One of the most intriguing recent developments is the introduction of X-LAM cross-laminated timber pods for use within existing stores. These are manufactured and fitted out in the factory and then delivered to site, and are designed to be up and running within a day of delivery. The intention is that they can also be moved around the store to suit future store refits.

Examples of such a design can be seen at the Tesco Store at Brighton, where two pods have been installed. The smaller of the two pods, a Tesco Direct store, was delivered to site in two sections, while the larger pod, a pharmacy and optician arrived in five sections. Both were installed and operational within a day of delivery.

Shared wisdom TRADA Technology senior technical consultant John Kirkby explains why the moisture content of timber is a critical factor in any joinery project When you look around at all the beautiful examples of timber wall panels, windows, doors, flooring, staircases and furniture in buildings ancient and modern, it is easy to understand why craftsmen choose to work with wood, and why architects and designers have specified it for centuries. No other material can offer the range of colour, figure and grain that catches the imagination and makes timber so unique.

TRADA has worked with joinery manufacturers on a range of new build and refurbishment projects including stunning buildings such as the Sage International Music Centre in Gateshead, London’s Royal Festival Hall and more recently King’s Place. Timber’s acoustic properties make it especially suited to concert hall venues, but it is equally at home in schools, libraries, visitor centres, offices and private homes, combining functionality with warmth and a pleasing appearance.

Controlling moisture is paramount Timber is hygroscopic, which means that it will absorb or lose moisture in response to changes in the surrounding atmospheric conditions (temperature and relative humidity) until it reaches what is known as the equilibrium moisture content. As timber gains moisture, it will swell and, as it loses moisture, it will shrink. When this occurs in service it is referred to as ‘movement’. Minimising the risk of movement is critical for any project involving timber joinery, and careful planning of the build sequence and close attention to detail at every stage of manufacture, transportation, storage and installation are required.

We are often called upon to provide assistance to joinery manufacturers who are under pressure from building contractors to install joinery products when the conditions in a building are frankly unsuitable – for example, before the heating has been turned on or while wet trades are still under way. Timber joinery needs to be manufactured, possibly stored prior to delivery to site, stored after delivery to site and installed in similar environmental conditions to those that it will experience in service. Such a requirement might mean that the contractor has to ‘bite the bullet’ and invest in a temporary heating system if the in-service system has not been commissioned when the joinery is delivered to site and installed. He might balk at the expense – but the remedial costs, should movement-related defects develop in the joinery in service, could be significantly higher.

Know the environmental conditions when tendering Normally, the tendering package for the joinery elements of the project should specify the temperature levels there will be in service, for example ’18-22oC, with 45-75% humidity’, or ‘Temperature range in accordance with BS EN 942’, the timber and joinery standard which provides guidance on this subject. If this information were not provided, the onus would be on the joinery manufacturer to confirm with the relevant party the environmental conditions that are likely to be present in the building in service. We would also recommend that the manufacturer monitor temperature and humidity levels within the building before installing the joinery to ensure that the conditions are as specified or predicted.

Once armed with the likely in-service environmental conditions, the joinery manufacturer will be able to identify the appropriate moisture content at which the joinery needs to be manufactured, which with today’s heating systems could be as low as 6-8%. (However, in some cases the moisture content of the joinery may actually be specified in the tendering package.)

BS EN 942 gives guidance regarding appropriate moisture contents for a range of internal temperatures. The manufacturer will then have to ensure that the temperature and humidity levels in the workshop matches the specified in-service levels for the end product – which might mean installing a temporary heating system. No one can afford to cut corners at this stage. While there is a little leeway in dimensional requirements for wood flooring, there is absolutely none for made-to-measure products such as windows and doors. They have to fit.

With any project of this type, it is important to understand the nature of the timber species in question as well as what the project would entail – in this instance the demolition of the existing pools and the replacement of the original heating system. There would be a significant period during the 22-month project where the building would be unheated and open to external conditions. The drying process of the concrete used to form new pools would also release large amounts of moisture into the building.

Above: Shrinkage in Cumaru flooring

Left: Shrinkage in Douglas fir bar top

In order to ensure that temperature and relative humidity are at the appropriate levels, continuous monitoring of conditions should be carried out. Moisture content levels in the joinery should also be monitored.

Effect of other works Similar stringent monitoring is also essential where existing joinery has to be protected during refurbishment. Some three years ago, TRADA was commissioned to provide guidance on the storage, protection, cleaning and redecoration of existing iroko ceilings and glazed screens at the Royal Commonwealth Pool in Edinburgh.

Shrinkage in pine flooring

What the contractors therefore had to appreciate was that environmental conditions within the building would be significantly different from when the building was in service, which in turn could have a significant effect on the moisture content of the timber components in the ceiling panels and in the glazed screens if they were retained in the building during the course of the project. Our recommendation was to remove certain components to safe storage while the refurbishment was under way.

In our view, there is a fine line between getting it right and getting it wrong. However, taking time at the start of a project to understand the overall programme of works and to confirm the temperature and humidity levels that are likely to present in the building will allow the joinery manufacturer to minimise the risk of movement-related problems developing in the joinery after installation.

John Kirkby says it is important to know the in-service environmental conditions prior to joinery installation

Form and function in window design TRADA Technology’s senior consultant architect Patrick Hislop RIBA discusses the balance between appearance and function of high performance wood windows As well achieving satisfactory appearance, a window must also meet the functional requirements of weather resistance, insulation, strength, safety, security, durability and economy. The detail design of the window profiles, components and accessories influences the appearance and overall performance of the complete window. It is important to ensure both satisfactory visual and functional performance.

There are various ways of meeting these criteria and the choice will often depend on a balance of visual and cost decisions, as well as the performance requirements. The dimensions of some parts of a window are quite critical to satisfactory performance and window frame design will need to conform to certain limits of size and shape.

Achieving high performance TRADA’s recommendations can be used either in the basic design of a window or act as a checklist when assessing a commercial design. It is important to realise that, although a particular design may not conform to all these recommendations, the windows may still achieve the required performance. Manufacturers should, however, be able to demonstrate that their windows meet the required performance when subjected to standard tests such as those for weather resistance and for security.

Our stance, however, is not to put forward proposals for any single standard profile to achieve the required performance, although this approach has been accepted in other European countries such as Norway and Germany, where the Rosenheim design for inward opening windows is used by all the German window manufacturers, as well as in Belgium, Switzerland, Italy and Austria. However, UK manufacturers tend to promote the differences in their individual window designs, rather than the similarities, and will probably continue to do so.

The final appearance of the assembled window is an important constraint on the design of window profiles. Enlarging the window, or omitting the subdivisions, often affects the scale of the windows in relation to the building as a whole. The large single pane pivot wood windows, frequently

used in the 1970s and 1980s, were not always suited to a UK style of house and this is largely the reason for their current reduced popularity, when a more ‘traditional’ appearance is preferred.

Popular window styles in the UK Windows in UK houses are generally subdivided into a number of smaller casements rather than existing as a single large opening light. Top or side-hung windows are therefore more popular than pivots, but the use of reversible and inward opening tilt-and-turn windows is increasing, particularly for individual house designs. Manufacturers have developed various methods of visually simulating small panes because it is expensive to subdivide large casements into a number of small insulated glass panels.

Surface applied glazing bars can be added to the inside and outside of the window and subdivisions by spacers can be enclosed between the panes of the glazed unit. These bars need to be firmly fixed to resist thermal movement of the glass as well as the activities of window cleaners.

If small panes are essential for visual reasons, for instance in a conservation area, it is often preferable to use a double window in which the outer frame is separately hinged and glazed conventionally with single glass panes in glazing bars, while the inner frame holds an insulated glass unit (IGU). These double windows need some ventilation to the outside behind the outer glazing in order to avoid condensation forming between the windows. A double window of this type, with the glazing spaced well apart, can achieve a better acoustic performance than an IGU alone Improvements in the thermal performance of IGUs are now encouraging the use of larger windows, particularly for non-domestic building. This is

because large windows can be designed to contribute to the overall passive solar gain of a building, as well as reducing dependence on artificial lighting.

Covered joint window design ‘Flush joint’ or ‘covered joint’ windows, however, look quite different. In covered joint design, a projecting nib on the casement conceals the joint between the casement and frame. In the flush joint design, the faces of the casement and sub-frames are flush and the joint is exposed. An internally stepped version of the flush joint casement has the advantage of allowing the glazing to be in the same plane in both the opening and fixed light. Some recent window designs have a stepped external face, as in a storm-proof design, but the sub-frame is rebated so that the nib on the opening light is still flush with the sub-frame when the window is closed.

With most covered joint designs, the glass is in a different plane in the fixed and opening lights. This difference in the plane of the glass is much more noticeable with IGUs than single glass panes, particularly where highly reflective low energy glass is used. Windows of flush joint design often have the fixed light glass set directly into the sub-frame, so that the plane of the glass is common to the fixed light and opening casement.

Although ‘stormproof’ joint design windows are still typical for houses in the UK, the flush joint design is in fact far more typical of traditional casement windows. Virtually all outward opening windows elsewhere in Europe are of flush joint design. The majority of UK windows consist of a sub-frame divided into panels by mullions and transoms. These panels comprise standard size opening casements and different size panes of fixed glass to make up the overall size of the window. This is referred to as the ‘equal divide’ type of window in BS 644. In this case, the sight lines vary between opening casements and fixed glazing.

Coupled-light windows The ‘coupled-light’ window is a common feature common elsewhere in Europe and is now offered by some UK manufacturers. In this case,

the fixed light is fitted in the same way as an opening casement but is not hinged. The sub-frames, coupled together, support the opening or fixed casements. This system has the visual advantage that opening and fixed casements are of the same size, with the same sight lines and with the glass in the same plane. This is particularly suited to pre-glazed casements that can be added after the sub-frame is installed, but it may be a more expensive solution than the ‘equal divide’ frame. It also increases the visual width of the mullions and transoms considerably.

Aluminium trims and facings Aluminium trim affects the appearance of wood windows. Many Scandinavian windows now use aluminium bottom beads, or even aluminium beads all round. These aluminium beads can be coated to match the colour of the wood finish, making them less obvious. If the windows are to be left unfinished, the wood will bleach out to grey and the natural grey of unfinished aluminium will match the eventual colour of the wood.

Several imported and UK-made window systems offer full aluminium facings which are clipped to the wood casements and sub frames, leaving a clear ventilated space behind the aluminium facings. Although these windows do not look like wood externally, the wood is visible on the inside and provides good thermal and acoustic insulation as well as a good appearance. There are also some systems using aluminium-framed opening casements in conjunction with wood sub-frames. Such composite windows are becoming more common, particularly for non-domestic applications, as they eliminate the need to repaint the wood frames externally.

Internal appearance Internally, junctions between reveals and soffits and window frames are important for the overall appearance of windows but are often unsatisfactorily resolved. Devices such as quadrant mouldings are often used to conceal the junction (between plastered reveals and soffits and the window sub-frame) where shrinkage cracks will inevitably occur.

Dry-lined or plastered reveals can obscure much of the internal face of the frame and, in conjunction with surface mounted mouldings, can spoil the internal appearance of the window. It also risks window frames being directly exposed to wet plaster which may adhere to the surface, requiring subsequent removal and possible damage to prefinished surfaces.

Providing more space between the frame and surround to accommodate the thickness of plaster or dry lining, or forming a rebate in the back of the frame into which the reveal can be inserted, can eliminate the need for additional mouldings and improve the internal appearance of the window.

Patrick Hislop doesn’t propose any single standard profile to achieve the required performance

Appearances can be deceptive Philip O’Leary, head of TRADA Technology’s Structural Investigations team, highlights his concerns about a lack of understanding in the industry about timber strength grading issues Timber, as a natural material, is inherently variable, even within a single species. Strength grading of softwood and hardwood overcomes this, by assessing the strength and stiffness of individual pieces intended for structural use and assigning them to a strength grade and/or strength class. Specifiers can then work with known and dependable mechanical properties.

The strength class is based on grade, timber species and where the timber was grown. There are 18 strength classes – groups of species/ strength grade combinations with similar properties – 12 for softwoods, prefixed C, and 6 for hardwoods, prefixed D. The most commonly used in the UK are C16/C24. The numbers represent the characteristic bending stress of the timber, a value which is called up in Eurocode 5 (EC5). So far so good.

pockets and insect attack, as well as slope of grain, distortion and even rate of growth, all of which may have to be considered. Note, however, that there are differences in the manner in which defects are measured for softwood, hardwood and scaffold boards.

In the UK, all structural timber, whether hardwood or softwood, should be strength graded in accordance with the umbrella standard BS EN 14081 Timber structures. Strength-graded structural timber with rectangular cross section. A Notified Body should oversee the training and certification of graders and the operation of grading machines. The UK national standards which comply with BS EN 14081 are: BS 4978: 2007 Visual strength grading of softwood - Specification and BS 5756: 2007 Specification for visual strength grading of hardwood.

And some of the rules are open to interpretation, for example on insect damage. The softwood grading standard BS 4978:2007 excludes active infestation and wasp holes, but other insect damage is permitted, provided it “conforms to the requirements of Clause 5”, the gist of which is that any piece which contains “abnormal defects” such as compression wood, insect damage or fungal decay that “could cause a decrease in strength properties to an amount which threatens the serviceability of the piece” must be excluded from the grades.

Another way of meeting BS EN 14081 is to CE mark, which might, but not necessarily, include grading to the British Standards – other European national standards could be called up instead. CE marking is a whole new topic, however, and best left for another day.

We have run visual strength grading courses for many years and our advice to candidates is not to be led too much by the general appearance of a piece of timber.

There is a limit, too, to how much time a grader can spend on an individual board, so graders have to learn to draw from their experience and trust their own judgement to make quick, accurate decisions.

Suppliers should bear this in mind when a customer is challenging a parcel that may not look the best, but has been correctly graded and, above all, will meet the requirements of its designated strength class.

Appearance is also a consideration Correctly strength-graded timber will fulfil its structural purpose, but it may not be pretty. Visual grading of structural timber relies on a correlation between the size of strength-reducing characteristics (defects) as observed on the surface of the piece and its effect on mechanical properties. The characteristics include knots, fissures, wane, resin-bark

Knowing what to look for

Re-machining and re-grading

To ensure that specifiers, inspectors and site staff are able to identify immediately the strength class and moisture content of the timber supplied, the rules dictate that each piece of strength graded timber must be stamped ‘clearly and indelibly’ on one face Another tricky issue for buyers, however, is that grade stamps can be falsified or applied incorrectly, so they need to know what to look for.

Just as there are rules governing marking, there are also rules governing re-machining. If graded timber has been re-machined, it will usually have to be re-graded. The limits for strength-reducing characteristics as stated in the rules may at times be open to interpretation, but the rules governing re-machining – which are the same for visually or machine graded timber – are very clear and the limits are quite tight. Take a piece of timber measuring 47mm x 138mm. If more than 10mm is taken off the width, the piece must be re-graded.

If in doubt, keep it dry Lack of care on site can also affect the grade. Timber, sadly, is often one of the least respected materials on a building site and bad handling or poorly organised storage are major causes of damage and wastage. The grading rules take account of this and clearly state: “Graded timber shall be protected in storage and transport to the extent necessary to minimise downgrading of the timber.” This may be open to interpretation, but commonsense should prevail – if in doubt keep it dry!

Using qualified graders The stamp must include the name or identifying mark of the producer, the strength class (or, if not included, the strength grade and grading standard), the words ‘dry graded’ if appropriate and the Notified Body. In some situations, marking may be omitted for aesthetic reasons, as long as a commercial document can be issued for each batch of a single grade of hardwood/softwood. This document must bear all the information that would otherwise be marked on the product and/or in other accompanying documentation. Buyers therefore need to check the paperwork if a consignment of supposedly strength graded lumber arrives unmarked.

Moisture content has a direct effect on strength; therefore, it is a vital factor in designing and specifying timber for structural use. TRADA Technology recommends that, wherever possible, ‘dry graded’ timber is specified, that is with an average moisture content of 20% or less, with no single reading exceeding 24%. Timber sections over 100mm in thickness can be difficult to dry without degrade, so are normally graded wet, that is at a moisture content above 20%.

Under BS EN 14081, wet graded timber is not required to be marked as such, which is an important clue for the designer or user – assume that the timber has been wet graded unless the stamp says otherwise.

Engineers will have applied modification factors if the timber being used is wet, because wet timber is weaker than dry timber. While it would be safe to install dry graded timber instead of wet, the opposite is not necessarily true – wet wood might not be strong enough. If dry graded timber has been specified, but the grading stamp does not clearly state that, then alarm bells should ring. If unsure, the contractor or builder must check the documentation and go back down the supply chain.

When TRADA Technology technical consultants have been called in to check the grading of timber, the outcome has varied hugely, from more than half of the consignment being rejected, to the parcel being totally in keeping with the rules. With grading generally, much of it comes down to the grader’s knowledge and experience. Companies that employ qualified graders know how valuable they can be, if the grading of timber coming into the yard or perhaps, more critically, going out comes into question.

Philip O’Leary says graders have to learn to draw from their experience and trust their own judgement to make quick, accurate decisions

Investigating timber in historic buildings There is a paradox that the older the building, and the more important it is, the more vital it is to get the work right. Yet at the same time, the more difficult it is, says architectural journalist Ruth Slavid

Infrared thermography is another useful tool. It can identify cold spots by creating a visual image of the temperatures within a building. These will show up areas of dampness within timbers, and can also be used to follow the course of a leak. It is essential, though, that the imaging is done at the right time of day, so that solar gain does not cause confusion.

If a building is really precious, conservation officers may be loathe to allow any meaningful investigation at all. To get a detailed reliable understanding of the properties of the structural timber, it is vital to make a thorough detailed examination, to probe it, and to take small bits away for laboratory investigations. But where you are dealing with important historic fabric that may be exactly what you are prevented from doing – at least at first.

Another technique, offered by specialist GBG Consulting, is vibration analysis. This is a method of modelling a structure, such as a staircase, and working out how it should behave. By then measuring the vibrations that can be induced, it is possible to discover not only if there is a problem, but also exactly where that problem is. “Timber is one of the most exciting areas we are working on at the moment,” David Wilson of GBG Consulting explained. “There are advances in software, and in data modelling.”

The worst situation, for somebody faced with understanding the condition and properties of the structural timber, is to be in a building with an ornate decorated ceiling and a fine, parquet floor. Just how do you get to the timbers sandwiched between? How do you find out if they are damp, or rotting, whether or not they will remain capable of supporting existing loads or of dealing with new loads that may be imposed?

Examining the timbers

This is an issue that John Williams, senior technical consultant at TRADA Technology, deals with regularly. Usually it is easier to lift a floor than to disturb a ceiling, but if neither can be done, it may be possible to examine equivalent timbers used elsewhere in the building – providing one is convinced of the equivalence, meaning that the timber has been constructed in the same way and is in a comparable condition.

In the end, though, there is no substitute for actually examining the timbers, for looking at their condition, and for testing to see if they have suffered damage. Williams emphasises how important it is to examine the right places – not just the beam that you can see, but also the bearing end. Less readily accessible, this is an area where water may be trapped, and also where rot will be most important – it is fine for a beam to be structurally sound in the centre, but if it rots at the bearing that is of no use to anyone. So even if the exposed timber appears to be sound, experience may indicate that one should test the bearing end.

And if there are any problems in the exposed timber, these are likely to be worse in the bearing end.

Non-destructive methods

Probing techniques

But before starting to take any part of the building apart, the first thing is to use non-destructive methods. The simplest one of all is the human eye. There can be tell-tales, just from looking at a building, that something is wrong. If, for example, the roof is sagging, there may be something wrong with the structural timbers.

The way to test the bearing end is with a digital microprobe, commonly known, after the manufacturer, as a Sibert drill. This has a drill bit that is 300mm long, but only 1mm wide. As the drill passes through the timber, it produces a graphical output that can be used to assess its properties.

Healthy timber that contains growth rings will produce a print-out that resembles a human heartbeat with its peaks and troughs. If this rhythm is interrupted, it can be an indication that there is an area of rot or even a void. Expertise is essential, both to ensure that the drill is used at the right angle, and to interpret the results.

But there are more sophisticated methods as well. Impulse radar is a good starting point, as it can identify the position of timbers (or other structural elements) in a building. Radio waves can cross air gaps that would stop acoustic waves, and so offer a good initial way to discover where the structural elements of a building are.

Decision path for investigating timber structures

Sibert drill results

The chart shows a drilling profile through timber 225mm wide. It shows sound timber for the first 5mm or so, decayed timber from a depth of 5mm to 50mm, and then sound timber from 50mm to 225mm timber A more robust tool is the Resistograph drill which will drive a 3mm diameter drill bit up to 440mm into the timber. By using a moisture meter along with the drill, the expert doing the testing can also discover how wet the timber is.

It may also be necessary to take samples of the timber away for testing. If the timber is really precious, the sample may be as small as a matchstick; where appropriate, samples up to the size of a cigarette packet can be taken.

Once the condition of the timber is well understood, it is possible to make key decisions. If the timber is sound, is it fit for its new purpose?

If the timber is wet, can it be dried or treated to prevent any decay? And if there is decay, what are the implications for the building, and how should it be dealt with? All these conditions may occur in one building – there may be some entirely sound timber, some damp but not rotted timber, and some timber that has rotted.

Eurocode 5: the supply chain perspective Senior structural engineer, TRADA Technology Ltd, Dr Keerthi Ranasinghe urges timber and wood products suppliers to consider CE marking or third-party certification to take advantage of the way Eurocode 5 has changed the approach to designing in timber

A key aim of the Eurocodes has been to create a common understanding regarding the design of structures among construction professionals.

This in turn was to lead to common design criteria and methods of meeting regulatory requirements. But the Eurocodes are also part of the drive to harmonise technical specifications and to eliminate technical obstacles to trade between EU member states, which opens up opportunities for timber suppliers prepared to do their homework.

Although Eurocode 5 (EC5) is very much a design code, suppliers should be aware that timber designers working to it need a product’s characteristic values for their calculations. Manufacturers and suppliers, therefore, need to understand what characteristic values are relevant for their product(s) and use approved or codified methods of testing to obtain them. A product certification scheme helps manufacturers and suppliers to obtain these values, as required by EC5.

Eurocode 5, the timber standard, consists of three parts: • Part 1-1: General – common rules and rules for buildings • Part 1-2: General – structural fire design • Part 2: Bridges.

Each part has its own National Annex (NA). All three parts have already been published, along with all the National Annexes, most of the supporting standards and most of the harmonised product standards.

There is little reason, therefore, for either designers or product suppliers to hold back from embracing EC5 wholeheartedly, apart from unfamiliarity.

Construction products and Eurocode The Construction Products Directive (CPD) classifies a “construction product” as a product “which is to be incorporated in a permanent manner in construction works”. The CPD requires EU member states to “take all necessary measures” to ensure that such products are sold “only if the product is fit for its intended purpose”. The CPD is incorporated in UK law

by the Construction Products Regulations 1991 (Amended 1994), which adopts the Essential Requirements (ER) from the CPD. Construction products, when they become part of a building, must conform to the Essential Requirements: • Mechanical resistance and stability • Safety in the case of fire • Hygiene, health and environment • Safety in use • Energy economy and heat retention • Protection against noise

Demonstrating compliance All products will be required to demonstrate that they have the necessary characteristics to achieve at least one, many or all of these ERs, depending on their end use and this is the responsibility of the manufacturer/supplier.

Although CE marking is not a legal obligation for construction products in the UK, demonstrating compliance with the CPD is and can most easily be done through CE marking for markets throughout Europe. An alternative is third-party certification under a national quality assurance scheme such as a BM TRADA Q-Mark scheme. The Q-Mark scheme, in fact, requires a higher level of proof of conformity than CE marking.

Although CE marking is not currently obligatory, things are expected to change – albeit slowly – and CE marking is likely to be incorporated into the regulations by 2013. We would suggest that manufacturers who want to steal a march on the competition look into CE marking ahead of time. It demonstrates both compliance with the CPD, and significantly a product’s “fitness for purpose”.

The award of a CE mark requires a specific level of input by a Notified Body, who may operate within and outside Europe to assess products for CE marking for use in Europe. In the UK, notified bodies for construction products include BM TRADA Certification, BRE and BBA. Notified Bodies are not enforcement agencies, and it remains the manufacturer’s responsibility to affix the CE mark to the product correctly. And it is the buyer’s responsibility to check that CE marked products are what they say.

A whole range of construction products and materials are already covered by harmonised product standards or through European Product Approval Guidelines (ETAGs) enabling them to be CE marked easily.

These include structural timber and related products (glued laminated timber, laminated veneer lumber or LVL, I-joists and other engineered wood products), wood-based panel products (plywood, oriented strand

board or OSB, particleboards, fibreboards), fasteners and connectors, trussed rafters and timber frame building ‘kits’.

Notified bodies can also help certify new products that are not yet covered by harmonised standards or ETAGs, a further opportunity for manufacturers to identify niche markets, perhaps.

TRADA’s involvement with Coed Cymru’s much publicised Ty Unnos ‘House in one Night’ project is a case in I-joists may already be CE marked point. The flexibility provided by the Eurocode 5 calculations approach was key to utilising the strength and other favourable properties of Welsh timbers, to develop a novel yet robust building system – with timbers that would otherwise have been used for lesser products.

Practical help from TRADA However, TRADA initiatives go beyond the classroom. Towards the end of last year, we initiated a number of projects with key stakeholders to orientate their existing practices to meet the exacting demands of EC5: writing design specifications, guidance documents, information sheets and even software tools for the use of the end users in these larger organisations. One such project was with British Waterways, the largest single end user for bulk timbers in the UK, to re-write all their design guidance and software tools to Eurocode 5.

The message is clear. The market is slowly waking up to all that EC5 can offer. Our advice to manufacturers and suppliers, therefore, would be to forget the grey areas of overlap between BS 5268 and Eurocode 5. The question is no longer when should we start learning about the essential requirements of Eurocode 5, but who will get there first?

Dr Keerthi Ranasinghe says Eurocode 5 offers endless opportunities for innovation

Endless opportunities for timber design Before, under British Standards, new materials could only be permitted in design when the standard was revised, so it could take literally years to have them included. Eurocode 5, however, separates the design method from the material properties, so these can be investigated and certified independently of the structural design codes. It is in our view only a matter of time before everyone involved in the timber industry wakes up to this potential, to make efficient use of existing timber materials and to come up with innovative designs that embrace new materials. With EC5, such opportunities could be endless.

In support of Eurocode 5, TRADA staged a whole series of seminars and workshops all over UK in 2010, to help the industry through this undeniably difficult time of transition. In 2011, we will take our free seminar programme, TRADA in the Regions a step further and include EC5 as a key topic.

Structures

Eurocode 5: a young engineer’s perspective Thomas Martin, graduate structural engineer with Burroughs, believes Eurocode 5 will push out the boundaries of what is possible in timber The engineering profession appealed to me as I was interested in architecture, design and the built environment. I have continued to find it a challenging and rewarding career choice and I am working hard towards gaining my professional qualifications. I have gained wide experience of projects from complex domestic timber-framed properties to large steel and concrete commercial developments. In addition to this work, I was given a key role in the development of a novel timber building system, Ty Unnos, (‘House in One Night’), a collaborative project between Coed Cymru, The Welsh School of Architecture, Gwalia Housing, Pontrilas Timber Group and Kenton Jones Timber.

It aims to develop a timber-framed, modular, affordable housing system using locally sourced lower grade (C16) Sitka spruce, hemlock and larch and which meets high BREEAM standards. This system is the first to use home-grown softwood in this way and has required much research and development.

comparable, there was more information within the Eurocode on dealing with built-up sections, which made it easier to push out the boundaries.

When I started working on Ty Unnos I decided to attend one of TRADA’s EC5 workshops to give me more confidence in using the standard and to have an informed second opinion on whether my interpretation of some of the clauses within it was correct. I had already looked into the Eurocodes for concrete and steel and they are all written in a similar way. One of the big advantages of that is that once you are into mindset of the Eurocodes, it is much easier to work with a new code.

Freedom and flexibility The course certainly helped me to use Eurocode 5 with confidence.

In addition, course tutor Dr Keerthi Ranasinghe, as part of the TRADA Technology engineering team, checked a further set of calculations, which again boosted my confidence in EC5 as the best design code for Ty Unnos.

Eurocode 5, in my view, gives more freedom and flexibility. Some might see the Eurocodes as set up for designing more by computer than by hand - and that is partly true. Some parts of EC5 can be long-winded and laborious, but that is partly down to a lack of familiarity. BS 5268 had more to offer in terms of reference tables, but I am sure these will come with the Eurocodes in time.

I have really enjoyed my work on Ty Unnos and using Eurocode 5 has offered more opportunity for clear sky thinking than might otherwise have been possible.

Eurocodes provide more information My involvement with the project began in 2008 when Burroughs was commissioned to undertake a feasibility study on the structural aspects, which involved carrying out a full set of structural calculations. At that stage we made the decision that using the Eurocodes was the best way forward. I did make comparisons with BS 5268 and although the results were

Thomas Martin graduated from Cardiff University in 2006 with a BEng in Architectural Engineering.

He attended a TRADA workshop to help him to get the most out of the design standard.

Save time with TRADA’s Eurocode design guides Manual for the design of timber building structures to Eurocode 5

timbersizerPro EC5 & timberconnectionsPro EC5

This manual and its accompanying CD provide qualified structural engineers with guidance on the structural design of single and medium-rise multi-storey buildings using common forms of structural timberwork.

timbersizerPro EC5 is a time saving online tool for architects, builders, engineers and other construction professionals.

It will help ensure their designs meet the requirements of Eurocode 5 (EC5), which replaced British Standard 5268 in April 2010, the British code for timber structures.

Structures designed in accordance with the Manual will normally comply with ‘BS EN 1995-1-1 Eurocode 5. Design of timber structures. General.

Common rules and rules for buildings’, together with its National Annex and supporting codes and standards. The manual is primarily intended for carrying out simple calculations and focuses on the design of buildings within the UK. The accompanying CD provides valuable connection design software in addition to more extensive tables of material properties.

Span tables pack: Eurocode 5 & BS 5268 calculations Also available separately, both editions of Span tables contain section sizes and spans for solid timber members in floors, ceilings and roofs (excluding trussed rafter roofs) for dwellings. The calculations apply to buildings up to three storeys in height above ground level. Span tables were originally included in the England and Wales Building Regulations, Approved Document A: Structure and subsequently revised by TRADA. Tables are included for domestic floor joists, ceiling joists and binders, and rafters and purlins supporting rafters for traditional pitched roofs.

Calculations are also given for “canted” purlins supporting roof sheeting or cladding, and for flat roof joists. The tables cover softwood species and grade combinations which satisfy strength classes C16 and C24.

This pack includes the 2nd edition with calculations to BS 5268 plus the new 3rd edition which conforms to the current British Standard supported by the British Standards Institution, BS EN 1995: Eurocode 5, which came into effect in April 2010.

Based on TRADA calculations, timbersizer EC5 covers all domestic structural timber members: • Joists for domestic floors, ceilings or flat roofs • Binders supporting ceiling joists • Rafters • Purlins supporting rafters, sheeting or decking.

timbersizerPro EC5 incorporates additional functionality for professional designers and generates custom reports in PDF format for records and Building Control purposes. Subscribers can further refine their design using advanced controls to adjust more parameters, for example: • The strength class • Breadth or cross section depth • Bearing length • Distributed imposed load • Concentrated imposed load

timberconnectionsPro EC5 is a design tool which calculates the resistance to lateral and axial loads of timber-to-timber, plywoodto-timber or steel-to-timber connections made with nails, wood screws, bolts or dowels inserted at right-angles to the grain. Timber types include solid timber, glulam and structural timber composites. Design loads are calculated to Eurocode 5. Coach screw connections for two-member joints are also included.

Eurocode 5 timberconnectionsPro is available on a subscription basis only. Rates are inline with timbersizerPro, with reductions for both modules together.

Eurocode 5: timber design essentials for engineers The adoption of Eurocodes, in April 2010, was a milestone in harmonising the approach to the design of structures across Europe. Eurocode 5 (EC5) being the current standard for structural design with timber. This pan-European approach will eliminate another obstacle to trade.

The objective of this publication is to pull together TRADA’s engineering guidance documents on EC5 into one, easy-to-use reference. It includes sections on: an overview of EC5; material properties; assessing design loads; calculating deformations (more commonly known as deflections in the UK); limiting vibrations; designing joints using multiple fasteners; designing flitch beams (laminated assemblies of timber and steel plates); designing with cross-laminated timber; plus an example calculation comparing BS5268 and EC5. This publication is only available in an electronic PDF format.

Essential timber frame standard details Saving countless hours of detail design, Essential Timber Frame Standard Details (for single occupancy detached, semi-detached and terraced houses) contains 32 of the most commonly-used drawings from TRADA Technology’s book and CD Timber Frame: Standard Details for Houses and Flats in a ready-to-use electronic format.

The drawings are in DWG (AutoCAD 2005) and PDF (Acrobat 6) formats, offering flexibility of use for designers.

This downloadable application is appropriate for low-rise buildings (up to three storeys) with concrete ground floors. It provides typical details for ‘open’ panel timber frame wall panels constructed using: - 140mm x 38mm timber studs and rails - 9mm or 12mm oriented strand board or plywood sheathing - breather membrane on the outer surface of the sheathing - mineral wool insulation between the studs - a polyethylene vapour control layer on the ‘warm’ side of the insulation - plasterboard as the internal lining surface.

Timber frame: standard and optimised details for thermal performance. Volumes 1 & 2 Mineral wool and Rigid foam insulation Designers following The Code for Sustainable Homes will find the thermal target for Code Level 3 matches the new 2010 Part L of the Building Regulations. Code Levels 4, 5 and 6 will be even harder to achieve. The 2010 Part L requires designers to analyse the entire fabric, with particular emphasis on cold bridging. The measure of heat loss via a cold bridge is the linear thermal transmittance (ψ-value), measured in W/mK. This electronic publication explains what cold bridging is, how to calculate the ψ-value and how to demonstrate compliance when using the standard details with mineral wool and rigid foam insulation. Working out the ψ-values needed to input to The Standard Assessment Procedure (SAP) can be taxing. Fortunately, software now exists to do the calculations. But even with the software, it remains a tedious process. SAP lists the situations in a typical building where cold bridging is likely to have a significant effect on overall thermal performance. TRADA Technology’s Building Performance Service has identified 20 critical details that arise in timber frame construction, and has calculated the ψ-value in each instance. Please note that this publication is only available in an electronic PDF format.

Wood Information Sheets (WIS) Wood Information Sheets are targeted documents providing concise information on a specific topic for designers and specifiers.

With over seventy titles in print they form a comprehensive source of vital information and when read in conjunction provide an invaluable guide on the use and properties of timber and its various uses within construction. Copies can be purchased as printed hard copies or electronic PDF documents via the online TRADA Bookshop.

TRADA members can also download PDF versions for free. The more recent additions include ‘Specifying timber species in marine and freshwater construction’, ‘Improving the thermal performance of existing timber frame buildings’ and ‘Modified wood products’.

New in 2011 Low-energy timber frame buildings: designing for high performance Geoffrey Pitts with Robin Lancashire Matthew Hoad of HTA Architects, London: “This book is refreshingly simple to understand and follows logical arguments on where to best deploy timber construction (and other materials) in high performance buildings.”

The energy consumption associated with buildings has consistently been estimated to be up to 50% of the total national consumption in industrialised countries and, of this proportion, residential buildings account for more than half. Timber frame systems are readily adaptable to the increasingly tough energy-saving regulations needed to cut energy use in buildings.

Firstly the author describes influential factors such as external climate, desirable internal environmental conditions and aspects of site planning.

He then focuses on residential building forms, the significance of internal planning and the construction system in designing low-energy timber frame buildings for high performance.

Low-energy timber frame buildings offers guidance on assessing the thermal resistance of the building envelope, together with a rational approach to thermal capacity and response of timber frame buildings.

This is developed in detail across the various building elements.

The book includes practical advice on choosing fuels and space heating, as well as exploiting renewable energy.

Timber bridges

Christopher Mettem Bridges built in timber are enjoying a significant revival, both for pedestrian and light traffic and increasingly for heavier loadings and longer spans. Timber’s high strength-to-weight ratio, combined with the ease and speed of construction inherent in the offsite prefabrication methods used, make a timber bridge a suitable option in many different scenarios.

This handbook gives technical guidance on forms, materials, structural design and construction techniques suitable for both small and large timber bridges. Eurocode 5 Part 2 (BS EN 1995-2) for the first time provides an international standard for the construction of timber bridges, removing a potential obstacle for engineers where timber construction for bridges has not – in recent centuries at least – been usual.

Clearly illustrated throughout, this guide explains how to make use of this oldest construction material in a modern context to create sustainable, aesthetically pleasing, practical and durable bridges.

Worldwide examples include Tourand Creek Bridge, Canada; Toijala, Finland; Punt la Resgia, Switzerland; Pont de Crest, France; Almorere Pylon Bridge, the Netherlands.

Eurocode 5 design software The new online edition of timbersizer EC5 is a time-saving design tool for engineers, architects, builders and other construction professionals.

It will help to ensure designs meet the requirements of Eurocode 5 (EC5), which replaced British Standard 5268, the code for timber structures, in 2010.

Based on TRADA calculations, timbersizer EC5 covers all domestic structural timber members: • Joists for domestic floors, ceilings or flat roofs • Binders supporting ceiling joists • Rafters • Purlins supporting rafters, sheeting or decking.

HOW DO I USE THIS BENEFIT? Visit the ‘Technical information’ area of the website and select the ‘Design tools’ link. Each program can be accessed from this page.

Users can access the online tool from a PC or MAC, whenever they choose. TRADA engineers maintain timbersizer EC5 to ensure it always reflects the latest version of Eurocode 5.

Construction briefing sheets These briefing sheets summarise the requirements of the main codes and regulations impacting construction. The briefings are regularly updated, with subjects including building regulations (England & Wales, Scotland and Northern Ireland), as well as the main codes such as the Code for Sustainable Homes (CSH), Eurocode 5 and Construction (Design & Management) (CDM) regulations.

timberconnections EC5 calculates the load capacity of individual fasteners based on timber strength classes C16 or C24. You can calculate connection capacities with nails, screws, bolts, dowels and coach screws in two and three member combinations of timber and steel. timbersizer and timberconnections are free to all TRADA members.

HOW DO I USE THIS BENEFIT? Each sheet can be downloaded in a PDF format by visiting the ‘Regulations & Codes’ area of the website and following the links.

This software is available on a subscription basis to members at a discounted rate.

Subscribers can customise and tweak all design parameters with advanced controls to define specific timber sizes and unload values for strength classes in the range C14-D70.

Both products generate custom reports in PDF format for records and Building Control purposes. These reports demonstrate where the design meets or fails to meet the requirements of Eurocode 5, and provide more detailed feedback for the user, including numerical strength stress comparisons of timber performance.
