Thanks to its superb efficiency performance, timber can help to reduce the lifetime costs of a building, resulting in reduced energy costs. It can also help to achieve faster delivery, thanks to the level of offsite construction possible when building in timber. And finally, timber is - as we all know the most carbon neutral material available.

staff in timber frame and truss manufacturers and across the CLT and SIPS sectors too.”

STA Chief Executive Andrew Carpenter believes that STA members are reaping the benefits of the hard work they put in during the leaner years. “This is definitely the proof of the pudding,” he says. “In the difficult times, the timber sector revolutionised many of its products, offering new systems to meet the needs of a changing industry, while also ensuring that staff and resources would be fully equipped for the economy to turn full circle. The timber sector has never been in a better place, and the rest of the industry is finally recognising that timber is the way forward in terms of sustainability, speed of build and high performance. It’s no wonder that the time for timber has finally come, and the

The Government continues to support the housing industry through the provision of finance for large scale projects, which is extremely welcome. Significant funding for large scale housing schemes offers the UK Government the chance to set standards for the future and further commit to off-site construction as the way forward.

Developments such as the 10,000 homes in Northstowe, would give the Government the chance to demonstrate how mass market sustainable and energy efficient homes can be built quickly and efficiently, through the use of offsite timber construction methods.

With its flexibility in design, inherent strength and environmental performance, ideal for both housing and commercial construction, a complete garden city could be built in timber – the case study of a lifetime.

ANDREW CARPENTER – Chief Executive, Structural Timber Association The announcement of new developments at Northstowe and Bicester are a positive step, but much more needs to be done if we are to end the housing crisis within a generation. The government needs to works with experts and local communities to deliver sustainable proposals. Short term value for money is not the only criteria of success for major new development, any government funding for house building must ensure that the houses and communities that are created are built to the highest standards. We need be building 300,000 new homes a year for the foreseeable future if we want to reverse the housing crisis. A new generation of towns designed upon the principles of the Garden Cities movement are only part of the solution. Freeing up public land for homes, supporting a greater diversity of developers including self and custom build and supporting institutional investment in housing should all be measures any future government should consider to really tackle the housing crisis.

STEPHEN HODDER – President, RIBA The Autumn Statement is both a shot in the arm – and a call to arms – for the construction industry. But the Chancellor has fired the starting gun as the industry is already sprinting at close to top speed. The scale and length of the contraction forced Britain’s builders to cut ruthlessly and shed thousands of skilled people. The players that survived the tough times did so by becoming leaner and smarter than ever before. With cranes once again dotting the skyline of cities across the UK, the construction industry’s contribution to Britain’s economic resurgence is more tangible than ever. But to continue the great strides it has made, it must do more to attract the brightest and best at all levels of the industry.”

JON WHITE – UK Managing Director, Turner & Townsend We welcome the increase in infrastructure spending, which will help boost the construction industry and promote future economic growth when the projects are completed. However, we are already seeing shortages of skilled labour and long lead-times for building materials, partly as a result of measures to stimulate the residential property market and the strong recovery in commercial property construction. These shortages may make infrastructure targets difficult to deliver on time and on budget. In addition to spending on infrastructure, we therefore need long-term investment in giving young people the skills required to enter the construction industry.

DAVID MANN – Executive partner, Tuffin Ferraby Taylor The National Infrastructure Plan will spend £466 billion on projects across the UK which could create over 2.3million construction jobs according to government estimates. While this type of investment is fantastic news for UK plc, we at the coalface know that finding skilled labour to build these projects is going to be exceptionally challenging. Alongside this investment in our infrastructure we need to see a recruitment drive to show people that construction is not a vocation but a respected career which is instrumental in shaping Britain’s future. This is something that we are committed to within our business model.

MARK ROBINSON – Chief Executive, Scape Group

TALL TIMBER GROWING IN POPULARITY

WE ARE VERY EXCITED ABOUT THE FUTURE OF TALL TIMBER BUILDINGS.

JAPAN The Japanese Forestry Agency and Land Ministry has created a roadmap to produce an annual 500,000 cubic meters of cross laminated timber (CLT) by 2024 with the aim of promoting the use of wood in buildings of ‘medium’ height. Japan is expected to use the material mainly for buildings with three or four storeys. According to the roadmap, production capacity will be increased from the current 10,000 cubic meters per year to 50,000 by the beginning of 2016.

The government plans to reduce costs by mass production and will also encourage the use of timber by developing related building standards and supporting model projects. Technologies to utilise the material in the flooring and walls of steel-framed housing will also be developed.

AUSTRALIA Timber buildings up to 25 metres tall could be a reality in Australia if a proposal under development comes to fruition. Forest and Wood Products Australia is working with industry groups and fire engineers to include a ‘deemed-to-satisfy’ requirement for the use of wood up to 25 metres, subject to the use of sprinklers for projects above three storeys as well as fire-resistant plasterboard on all exposed wood. FWPA Managing Director Ric Sinclair says the idea is not just to increase the height up to which lightweight timber construction is allowed but also to introduce engineered timber into the building code. “What we want to do is take lightweight timber construction, which can be used up to three storeys for both Class 2 and Class 3 buildings, much higher, but also introduce mass timber construction like cross laminated timber (CLT) [into the building code.”

If approved, Sinclair says the changes would reduce construction costs of tall timber buildings, which in turn would make timber accessible as an option to second and third tier developers. If the proposal is ready by the due date (February 1, 2015) and subsequently approved, the new rules will be implemented in 2016.

SOURCE: http://sourceable.net/timber-buildings-could-rise-to25-meters/#sthash.yVB1WjZ5.dpuf CANADA North America’s tallest modern timber building recently opened its doors in Prince George, British Columbia (BC). The $25 million Wood Innovation and Design Centre (WIDC) was built to LEED Gold status. Designed by Michael Green Architecture, the 50,000 square foot, 30 metre high landmark is located at the corner of 5th Avenue and George Street.

The building program includes demonstration space on the main level with classrooms, a 75-seat lecture theatre and research facilities for the University of Northern BC’s new master’s programs in wood engineering. More than 1,700 cubic metres of wood was used for the primary structure, exterior cladding and interior finishes. The building relies almost exclusively on engineered wood components including glulam columns and beams, cross-laminated timber (CLT) for the floor assemblies and core vertical panels and laminated veneer lumber (LVL) for areas such as the feature stairs and canopy.

With the BC building code currently limiting wood structures to six storeys, this project required a special exemption in the form of a site specific regulation (SSR) issued by the province. The centre is defined as a six-storey building but stands taller because of a double height mezzanine at the first level and a high floor-to-floor ratio. PCL Constructors started major construction in the summer of 2013 and achieved near completion by the end of August, 2014.

The building opened at the end of October 2014.

NEC BIRMINGHAM The Structural Timber Association (STA) had a high profile at the event and used Timber Expo as the launch platform for their new Structural Timber magazine. With an objective to engage and inform, the magazine features in-depth case studies, introductions to structural timber solutions and feature articles. The STA also saw a huge increase in membership interest that was a direct result of being at the show.

Once again the Timber Buyers & Specifiers Forum was hailed as a great success and acted as an excellent way to explore ideas, innovations and network with serious business potential on offer. Atit Kumar, Architecture Business Owner, Tesco Stores Ltd said: “It’s a great event. A lot to get out at a personal level and the Buyers & Specifiers Forum is the best use of my time.

BIG BOOST FOR TRADA TRADA was delighted to report another successful Timber Expo, with an excellent level of enquiries and a steady stream of interested individuals on its stand – all wanting to know more about wood.

The leading authority on wood

With a busy seminar programme reflecting some of the industry’s leading names talking about the hottest topics, interactive quizzes and seminars on its own stand, it was a busy two days for the TRADA team. The Timber Focus seminars featured over 50 renowned speakers from across the built environment. The format went down well with visitors and all chairmen have reported lively and engaging Q & A sessions because of the great content that was delivered by people who knew their subject well.

ADVERTORIAL

TENMAT Cavity Fire Barriers out perform cavity socks in more ways than one Tenmat have simplified the whole process of installing cavity fire barriers into one simple and cost effective product, the TENMAT Firefly Cavity Fire Barrier on a Roll.

This intumescent cavity fire barrier is only 4mm thick leaving the external wall cavity open resulting in cavity trays, weep holes and vent slots not being required at each floor level. This saves on installation costs as well as giving the building a “clean” finish, significantly improving the aesthetics of the building.

The Firefly Cavity Fire Barrier on a Roll is simply stapled, screwed or nailed in position and the 6.3 metre length ensures that bulk for shipping and on site is kept to a minimum.

Traditional cavity barriers and associated accessories can be prone to gaps and imperfections due to poor installation or building irregularities. This has been shown by test to lead to premature fire spread, as well as potentially leading to costly insurance claims if moisture bridges the cavity causing damage on the inner wall.

The benefit of a thin intumescent cavity fire barrier is that the cavity is not bridged and so moisture cannot be transmitted from one side to the other. The product is also supplied in longer lengths which minimises the potential for gaps to be evident.

The intumescent nature of the Firefly Cavity Fire Barrier on a Roll means that it only operates in a fire situation which causes the material to expand rapidly to create an active seal to fire and smoke in the cavity. The added benefit is that as the material expands it takes up all of the changes in cavity width and building irregularities which a standard cavity barrier does not. Once again, this has been proven by test to outperform traditional cavity barriers.

The Firefly Cavity Barrier on a Roll is fully third party fire tested and suited to a wide range of cavity sizes, with and without common cavity insulation and in combustible and non-combustible cavities.

GROWING OUR LOW CARBON ECONOMY The £8.5bn timber industry has a significant role in promoting the UK’s low-carbon economy and a report by the Timber Accord - an alliance of the UK’s timber trade associations – picks out several areas the timber industry can help UK Government focus upon to boost the economy as well as reducing carbon emissions. David Hopkins, executive director of Wood for Good explains.

TIMBER FRAME – THE RIGHT APPROACH TO FIRE RISK After the devastating fire at The University of Nottingham’s £20 million GlaxoSmithKline Carbon Neutral Laboratory for Sustainable Chemistry last year, doubts were once again cast over the vulnerabilities of timber during the construction phase.

SIPS TECHNICAL BULLETINS Structural insulated panels (SIPS) are one of the leading ways to construct energy efficient, cost-effective and sustainable buildings.

This bulletin covers all aspects of the building phase from walls, floors, roofing cladding and services to tolerances for walls and sole plates. There are two fundamental applications for SIPs – full structural and infill for a concrete, steel or engineered timber frame. In all cases the product will be engineered for loadbearing capability, racking resistance and wind loading. SIP buildings can be designed and built as either a platform or balloon framed structure. Platform framed buildings consist of room height panels with intermediate floors bearing onto the head of the walls panels.

Balloon framed buildings consist of storey or building height panels with the intermediate floors hung from the inside of the walls.

All forms of construction need to comply with the fire performance requirements laid down by national Building Regulations. There is no difficulty in SIP- based structures meeting the required levels, given correct design, standards of manufacture and workmanship.

The fire resistance of a SIP structure is primarily achieved by the use of fire resistant lining materials. All forms of construction need to comply with the fire performance requirements laid down by national Building Regulations and there is no difficulty in SIP based structures meeting the required levels, given correct design, standards of manufacture and workmanship. In considering the complex phenomenon of fires, two main stages are recognised and these are reflected particularly in the testing carried out to determine the fire performance of buildings.

This bulletin covers the improved sound performance levels that can be delivered by SIP panels. SIPs contribute to improved airborne sound insulation for floors roofs, external, internal and separating/party/compartment walls. Much like timber studwork, SIP panels rely on the mass and continuity of plasterboard linings to provide the majority of the sound insulation performance. SIPS, much like timber studwork, relies on the mass and continuity of plasterboard linings to provide the majority of the sound insulation performance. If the sound insulation performance of the wall needs to be improved, the use of acoustic rated plasterboard in multiple layers is normal. Remember an acoustic consultant would need to be involved to determine specification and performance requirements.

• Ignition and fire growth: The behaviour of a material in this stage is termed its ‘reaction to fire’ and covers aspects such as ignitability, non-combustibility, and the contribution that a material makes to the development of a fire. SIP structures do not contribute to the growth of a fire because they are normally protected with non-combustible wall linings.

• The fully developed fire: At this stage a material contributes to the fire resistance of an element of building structure (such as a wall or floor). Fire resistance can be defined as the ability of an element to carry on performing a building function in spite of being subjected to a fully developed fire. The fire resistance of a SIP structure is primarily achieved by the use of fire resistant lining materials. SIP construction can be designed to meet Class O surface spread of flame and up to 60 minutes fire resistance.

6. Sustainability

‘Fabric First’ is a popular ethos that has grown from the German Passivhaus standard. This is where energy efficient buildings are created by focusing on the performance of the external envelope of the building before using or ‘bolt on’ renewable energy technologies.

With SIP structures excellent U-Values can be achieved. Learn more about U-Values, thermal bridging, air permeability and SAP Assessments.

The long term performance of a SIPs building will be largely dependent on repair and maintenance. During construction the SIP structure may be exposed to the prevailing weather conditions and may be exposed to rain. This is not an issue for SIPs as long as a number of general precautions are followed. Cladding systems can take the form of masonry such as brick, rendered block work or stone or lightweight systems such as timber, metal or proprietary render systems. SIP external wall sections are clad and lined in a similar way to timber studwork buildings. The SIP structure itself is protected from moisture by both the cladding and the breather membrane on the outside of the panel, as well as a cavity. Cladding would normally take the form of masonry such as brick, rendered block work or stone or lightweight systems such as timber, metal or proprietary render systems.

For construction to be sustainable, the basic principles of sustainable development must be adopted. The UK Government’s strategy for more sustainable construction widens the basic themes to suggest key actions by the construction industry. These include designing for minimum waste, lean construction, minimising energy use in construction and avoiding pollution. SIPs offer a relatively low embodied energy building system with good long term thermal and airtightness performance and are also able to offer a long design and service life. SIPs offer a relatively low embodied energy building system with good long term thermal and airtightness performance and are also able to offer a long design and service life.

They also provide minimum waste, are a lean construction method, minimise energy use in construction and avoid pollution.

Energy efficiency of buildings is generally broken down into three key areas of performance: • U-Values of building elements • Ψ-Values (thermal bridging) of element junctions • Air permeability of the building envelope – heat loss through unplanned air infiltration e.g. around windows or external doors, or air infiltration at service penetrations.

U-Values of building elements deal with the heat loss through the walls, floors, roof, windows and external doors. Ψ-Values (thermal bridging) of element junctions deal with the additional heat loss at junctions in elements, e.g. wall/foundation junction, or at corners.

SIPs are constructed by laminating layers of Oriented Strand Board (OSB) to an insulating foam core. Most OSB used in the manufacture of SIPs will come from manufacturing plants in the UK or Europe and will be made from sustainably sourced softwood timber.

Sustainable timber will come from managed forests and will be certified by an organisation such as FSC or PEFC. A number of UK-based manufacturers of OSB use homegrown timber in the manufacture of their products. It is also possible that the manufacturer has used a proportion of recycled material. Nearly all of the structural softwood used in the UK construction industry will come from certified renewable sources in UK and Europe. SIPs generally achieve BRE Green Guide ratings of A and A+ for wall and roof elements.

BANYAN WHARF TOPS OUT London’s tallest cross laminated timber (CLT) building, designed by architect Hawkins Brown, has topped out in November. The 6,750m2 mixed-use project, for client Regal Homes, is part of the Banyan Wharf development in Hackney and will include office and residential space. The frame of the 10-storey high building is being built by B&K Structures, mostly from cross-laminated timber with a small amount of steel to minimise its environmental impact. The building, which sits on the edge of the Regent’s Canal conservation area, will be covered with a dark brick screen and red cedar cladding when it is completed in 2015.

vapour permeability. George Watson, product manager for Coillte Panel Products takes a look at the introduction of breathable external sheathing panels and how they can be used in timber framing applications.

When considering the thermal efficiency of new buildings, especially when using timber frames to build to Passive House standards, interstitial condensation can pose a particular risk. At best standing moisture results in mould growth, which is not only unsightly but also presents health issues. At worst it erodes building fabric to the point that safety and structural integrity are compromised.

As a result, Coillte Panel Products has launched Medite Vent to its range of Medite products, which is ideally suited to the needs of the timber frame and off site construction industry. Medite Vent suits the need for a breathable panel for use in external

A Media 10 event

Explore the latest innovations in offsite technology

A series of one day conference and exhibitions creating a platform for construction clients and their professional advisers to explore the latest offsite construction solutions, by providing dynamic and interactive learning experience for all attendees.

03 February 2015, London An introduction to Offsite The first in the series focuses on the pioneers that are embracing offsite construction as part of their day to day activity.

21 April 2015, Nottingham Offsite in the Education Sector With only 63% of projects delivered on time and only 49% delivered to budget, traditional build fails to meet the major challenges facing the education sector. Technology leaders discuss the opportunity this presents for offsite construction to play a major role in the coming years.

07 July 2015, Birmingham Offsite in the Housing Sector Discover the challenges facing the housebuilding industry and why offsite construction is likely to be a major component in solving the housing shortage.

24 November 2015, Leeds Offsite in the Commercial Sector With many commercial facilities in use 24/7 with zero down-time, the quick and efficient delivery of new buildings is vital. Find out how Offsite methods can provide faster, leaner and smarter construction solutions to this dynamic sector.

These events will consist of a conference of circa 200 delegates and an exhibition of circa 30 companies from a range of offsite technology providers including; timber frame, light steel frame, precast concrete, bathroom pods, volumetric buildings, building services plus CLT, glulam and a range of hybrid technologies.

Delegate discounts are available for multiple bookings via www.exploreoffsite.co.uk BOOK YOUR EXHIBITION SPACE If you are interested in participating in any of the events as a sponsor or exhibitor contact Julie Richards on 01743 290001 or email: julie.richards@radar-communications.co.uk For all other enquiries please contact hannah.jones@radar-communications.co.uk or call 01743 290048
