Rise of timber driven by carbon reduction and improving building performance 

 

High performance timber windows and doors manufacturer, NorDan UK Ltd, has announced a record 34 percent increase in turnover for a single year for 2022.

NorDan’s turnover has increased year-on-year since 2016 and has grown more than 85 percent in the last five years.

Sustained growth across private and public customers is further evidence of changing priorities in the construction industry, with an increasing focus now on the whole life carbon reduction of buildings and the lengthening the lifespan of products and materials.

Originally conceived to withstand the harsh rigours of a Nordic maritime winter, NorDan’s timber and aluminum-clad timber windows and doors have been known as a niche product, offering some of the industry’s highest standards in thermal performance and durability.

But with architects and specifiers now seeking materials that meet the changing demands of developers and housebuilders, NorDan’s products are now becoming a mainstream in UK building.

This is being heavily influenced by the Future Homes Standard (set to come into force in 2025), with numerous big social landlords and local authorities already specifying and building to that standard – including the likes of NorDan customers Reading Council and Clarion Housing Group.

The sale of timber products has also been driven by an increasing need to reduce whole life carbon of buildings, including the embodied carbon emissions generated from the manufacture, transport, installation, and eventual disposal of building materials.

NorDan is one of the few construction suppliers that has Environmental Product Declarations (or EPDs) on virtually its entire product range, proving third-party validated audits of all the carbon in its products.

 

 

Alex Brown, NorDan UK Managing Director said: “Last year’s record growth is obviously very pleasing, but 100% consistent with the wider direction of travel in construction and the built environment.

“People have long known that NorDan’s timber products are carbon negative and offer a 60-year lifespan but have maybe in the past needed a reason to specify what were perceived premium windows or doors.

“What we now see is low carbon, durability, and high-thermal performance becoming the new mainstream, and this is taking NorDan’s and other quality timber products with it.

“Architects and developers are now seeking incremental gains across buildings to meet raising industry standards, as well as the expectations of the public, and NorDan can give them the low-carbon, high-performance guarantees sought.

Alex concludes: “Looking ahead, NorDan UK’s priority is to continue developing its people and infrastructure to maintain anticipated accelerated growth over the coming years.”

 

Mat Clarke, Contracts Manager at contractor Henry Boot Construction comments:

 

“Sustainability, and reducing the whole life carbon impact of building, has become an increasing priority for Henry Boot Construction in recent years, and we now routinely seek out sustainable suppliers and partners.

“As a result, we are increasing the amount of timber we use in our construction projects, and this has made NorDan a natural choice, as it places sustainability at the heart of its operations and products.

Mat continues: “A recent example of this can be found at our marquee development at The Cocoa Works in York, where NorDan’s products have the specification to achieve a high environmental and energy performance.”

 

Ayo Allu, Director of Design, Technical & Innovation at NorDan customer Clarion Housing Group comments:

 

“Material costs and the impact of embodied carbon calculations on business performance is increasingly driving the way Clarion is constructing its buildings, as is our familiarity with the timber products on the market, and the vast increase in testing data compared to previous years.

“Embodied carbon is already a development consideration within major cities, and the GLA how has an embodied carbon tool which has to be completed for each new development – with other cities set to follow suit.”

Ayo concludes: “As a development business, we’re now benchmarking our embodied carbon for development and construction activities for the second year running, so we can set reduction targets for ourselves and our supply chain.”

 

 

 

 

 

 

Both Henry Boot Construction and Clarion Housing Group are working with NorDan on the iconic Cocoa Works refurbishment project in York.

 

 

NorDan UK is the British arm of the Norwegian founded NorDan Group, a multinational business that operates in seven European countries, employing 2,200 people across 12 factories and 35 sales offices.

Caerphilly-based social enterprise, Celtic Offsite, has teamed up with one of the UK’s leading timber suppliers, Premier Forest Products, as part of their ambitious plan to develop a Welsh supply chain to reduce its carbon footprint and support the local economy.

Celtic Offsite, part of the United Welsh Group, manufactures low carbon homes by producing high quality, sustainable timber frame structures, complete with factory fitted insulation and windows, to build up to 250 low carbon homes a year.

Premier Forest Products was initially approached by Celtic Offsite to supply Oriented Strand Board (OSB) for sheathing for timber frame panels, plywood and chipboard. However, thanks to Premier’s growing product offering, they have recently started supplying roof trusses, engineered floor joists and Laminated Veneer Lumber (LVL) for structural beams, taking Celtic Offsite ever closer to their goal of using Welsh suppliers for more of their manufacturing work.

Neil Robins, Managing Director of Celtic Offsite said: “We are actively committed to making the areas in which we work better and more environmentally sound. We have been certified as a Climate Positive Business by Earthly, meaning we will remove more greenhouse emissions than we produce. One of the ways that we will do this is by working with local suppliers who have a similar mindset to our own.

“We have been so impressed by the service and quality of the products supplied by Premier Forest that we have consistently increased the range of items that we order from them.”

 

Co-founder and CEO of Premier Forest Products Terry Edgell said: “As an organisation, we firmly believe that the use of timber should be at the forefront of sustainable housing development. At the moment, wood in construction is the only commercially viable carbon capture and storage system so, simply by using more wood in construction, we can turn our built environment into a weapon against climate change.

“It is so inspiring to be working with an organisation in Wales that not only recognises the benefits of using timber but is actively working to build a sustainable supply chain, hopefully changing the way that homes are built.”

 

Premier Forest Products is a vertically integrated timber operation engaged in the importation, sawmilling, processing, merchanting, and wholesale distribution of timber and timber products from its 12 sites in the UK.

As part of its commitment to the local community, Celtic Offsite offers an on-site training suite to provide skills development and apprenticeships for green construction jobs.

The factory has been awarded two prestigious International Organization for Standardization (ISO) certifications; ISO 9001 for quality management and ISO 14001 for environmental management. Celtic Offsite has also achieved PEFC certification for the chain of custody of forest-based products and were awarded Gold by the Structural Timber Association in their latest audit.

Construction, property, and facilities company, The Sovini Group, are investing in offsite construction as part of their ongoing Net-Zero Carbon Commitment.

The Group who boasts a unique end-to-end supply chain is supporting their wider environmental strategy with their latest initiative in the form of adapting raw materials for the new build construction arm of business, Sovini Construction. The highly advocated method of construction is set to facilitate the Group’s development framework to deliver 1,000 new high quality and affordable homes within the next four years. Their newest shift in sustainable construction management is the latest in a longline of ecological and biodiverse plans for delivering affordable social housing across the North West.

 

Time for timber

The structurally graded timber is sourced from Scandinavia and delivered to the Group’s independent builders’ merchant, Sovini Trade Supplies.  The climate-smart raw material is then transferred to a local Merseyside-based organisations, timber frame specialist SticX. The award-winning team at SticX use the latest 3D CAD software to integrate the main architectural design of the structures. Once constructed using the PEFC certified timber, the frame is compartmentalised and transported to site where it is erected.

 

The Sovini Group’s timber framed homes provide a significantly lower carbon footprint through its manufacturing, reducing energy consumption throughout its lifetime and locking-away atmospheric CO2 for generations. John Maddock, Director of SticX shares: “Timber Framing is a great solution for The Sovini Group. For a client who’s genuinely concerned about sustainability it scores highly. By partnering with them, we can help develop improved solutions to save money and time. Ultimately, using timber frames means they can provide higher quality houses for their clients. We’re also a local company, so their spend stays local and benefits the Merseyside economy. We’re delighted to share our expertise with such an enlightened and progressive client”.

 

The Group uses recyclable materials which is designed to achieve superior levels of fabric performance, suitable for their projects which are seeking to achieve the very highest fabric efficiency, airtightness standards, and sustainable credentials.  The Sovini Group recently welcomed timber frame specialist SticX to their flagship Morris Meadows development in Merseyside to view the environmentally friendly materials come to life.

 

Sustainable Social Housing

The Sovini Group create thriving and inclusive communities which are well-integrated into wider urban systems.  The offsite construction has proven performance, providing an advantageous construction method for affordable housing and with the Group’s timber frames being produced off site and delivered in a prefabricated form, construction times to make a building ‘wind & watertight’ can save as much as 30% over that of traditional construction.  Employing over 800 colleagues, The Sovini Group is a key contributor to the social, economic, and environmental development and future growth across the North West.

UPM’s ultra-sustainable new technology, WISA BioBond, becomes standard bonding agent in all James Latham Ltd’s collection of UPM WISA-Spruce.
Today, James Latham Ltd (Lathams), one of the UK’s leading independent distributors of panel products, announces the introduction of WISA®’s new BioBond technology to its full range of WISA-Spruce plywood.

WISA BioBond is the latest bonding innovation from UPM, a globally-renowned manufacturer of sustainable architectural plywood, now used in the entire WISA-Spruce range.
A landmark development in plywood adhesive, BioBond replaces at least 50% of standard glue’s fossil-based phenol with lignin, timber’s inherent bonding agent.
Obtained as a by-product of the Kraft Process1, this partial-substitution reduces the carbon footprint of WISA-Spruce by approximately 10%, without compromising technical performance or visual appeal.

No compromise on performance
WISA-Spruce is manufactured using UPM’s proprietary BioBond technology, and mirrors the qualities of plywood produced using the traditional higher-carbon bonding method. This means it offers a like-for-like greener alternative.
As with all WISA’s plywood, WISA-Spruce with BioBond technology has undergone rigorous testing to guarantee its high performance qualities, meeting superior standards of strength, resistance and sustainability.

Forming a strong and sustainable bond
More than just a new form of glue, BioBond has reduced CO2 WISA’s plywood portfolio, Already available for birch, and now spruce, plywood, UPM plans to roll out BioBond across all its plywood mills, gradually covering its entire range.
As one of the UK’s most sustainable materials distributors, Lathams is keen to introduce UK specifiers to the low-carbon advantages of WISA-Spruce with BioBond technology. By incorporating this innovation to its ever-expanding collection of green architectural materials, they are demonstrating their ongoing commitment to supporting sustainable design and build.
Commenting on the introduction of BioBond to the WISA-Spruce range, Nick Widlinski, Panels Director at Lathams says, “There’s no doubt timber and wood-based materials are helping architects and designers tackle global climate change through making lower-emission material choices. However, a question around the carbon intensity of glues and adhesives used in the production of engineered wood persists, and WISA BioBond tackles it head on. Its introduction and standardisation across the brand’s high-performance spruce range is a game-changer, offering the best quality with a reduced carbon footprint. Not only is it helping us to promote more sustainable construction methods, it’s also supporting a wider drive toward a Net Zero society.”
UPM’s VP of Strategy and Business Development, Susanna Rinne, concludes, “Sustainability is at the heart of our ethos and guides our ongoing R&D. We are the first manufacturer in the world to use a lignin-based solution for spruce and birch plywood, offering a no-compromise sustainable material solution. It’s imperative we work with those who have similar values. Due to Lathams’ longstanding reputation for championing sustainable specification make them a great partner to help us introduce BioBond and its unique properties to the UK and Irish markets.”
Providing further confidence in WISA-Spruce’s green credentials and certification, the product category scored one of the best ratings on Lathams’ new Carbon Calculator tool. An academically developed formula which scores the embodied carbon of each Lathams’-stocked timber product from cradle-to-purchase, BioBond WISA-Spruce achieved top ranking across the board, providing third party verifications for the material’s sustainability claims.

1. The method used to convert wood into wood pulp

Sleek, sustainable and striking, the recent development by Haslob Kruse + Partners fuses past and present with an expansive wooden exterior made with sustainable leader, Kebony wood, which was selected to house over 60,000 precious maritime artefacts at Germany’s National Maritime Museum in Bremerhaven.

Clad entirely in sustainably sourced Kebony Character wood and containing 2,300 square metres of depot space, the German Maritime Museum houses an extensive collection of archival materials and museum objects: preserving Germany’s maritime heritage with a forward-thinking and eco-conscious approach to architecture.

Designed with a focus on modernity and eco-conscious construction, the German Maritime Museum has harnessed the latest developments in warehousing, air conditioning, and technology, whilst simultaneously making use of sustainable materials in the construction process. The result is a museum depot which is vast in size, but grounded in environmentally-sound practice, which also offers a solution to concerns about limitations in space to contain this precious historical collection.

Created to enable future generations to better understand the relationship between man and the sea, the depot contains an extensive collection of 380,000 archival materials and 60,000 museum objects. This unique maritime vision is realised by the joint pattern of Kebony wood, which resembles the hull of a wooden ship, creating a unique sense of place which is both striking and recognisable.

Kebony’s modified timber is dimensionally stable, long-lasting, and preserves its natural aesthetic for many years. The durability of the material means it will require as little maintenance as possible and withstand the high stresses on the building from wind, weather, and salt water.

A global leader in the production of environmentally friendly wood, Kebony’s pioneering wood-processing technology sees sustainably sourced softwoods heated with furfuryl alcohol, an agricultural by-product, modifying it to maintain the same durable properties of industrial hardwoods without the need for extensive deforestation. Kebony wood is both cost-effective and visually attractive, retaining a natural aesthetic in keeping with the maritime theme of the museum.

 

Jens Kruse, Architect at Haslob Kruse + Partner Architekten BDA, commented: “We discussed for a long-time which material would be suitable here on the water with the salty air and the strong wind. In the end, together with the client, we opted for Kebony wood because it is a very durable and easy-care wood and is also produced sustainably.”

 

Nina Landbø, International Sales Manager at Kebony, commented: “The German Maritime Museum in Bremerhaven is the perfect setting for preserving the rich maritime history of the area. We are pleased to have been involved in such an exciting and important project, which has a long-life guarantee for future generations to enjoy.”

 

 

 

As the UK Construction industry works towards reducing carbon emissions, John Smith, technical director at Donaldson Timber Systems, discusses why embodied carbon is critical to its success.

 

 

The journey to Net Zero Carbon homes is well underway, with the first Building Regulations changes already in effect as we work towards the Future Homes Standard.

From 2025, newly built homes will need to be ‘zero carbon ready’, with a 75% reduction in carbon emissions to 2021 levels in England and Wales, and a 57% reduction in Scotland.

Reducing the requirement for energy in the home is the first step, before introducing low and zero carbon energy sources to provide heating and power. Fossil fuel heating is likely to be banned – or at least carry a significant penalty – in new homes, with a shift to new heating systems like air source heat pumps. These heating systems are only efficient with a high performing building envelope, so the introduction of a Fabric Energy Efficiency measure within these latest changes is a necessary, and welcome step.

At Donaldson Timber Systems (formerly Stewart Milne Timber Systems), we’ve been advocating for this build method for over 15 years. Our BOPAS Plus accredited and BBA certified Sigma® II Build System is designed to achieve superior levels of fabric performance, suitable for projects which are seeking to achieve the very highest fabric efficiency and airtightness standards.

 

Embodied carbon

While the Future Homes Standard is a much-needed step in the right direction, more clarity is required on what it means to be carbon neutral. When we talk about ‘zero carbon’, we should really be thinking about the cradle to grave impact of the build and the unintended consequences along the way.

For us, the most crucial factor when it comes to reaching true zero carbon, is embodied carbon. Embodied carbon is the total greenhouse gas emissions generated in production and manufacturing of an asset. It can be calculated in two separate elements: from raw material extraction through to construction of the building on site, including fuel and power for transport, factories and plant; and end-of-life emissions from demolition, transport from site and recycling / landfill.

In 2021, the UK Green Building Council (UKGBC) developed the Whole Life Carbon Roadmap for the Built Environment, which indicates that the impact of embodied carbon is set to increase and will form over half of built environment emissions by 2035. Despite this, embodied carbon emissions are currently unregulated in the construction industry, with only voluntary measurement and mitigation required.

In a new home completed to 2021 standards, embodied carbon from the construction and end of life demolition and disposal is around 15% of the whole life carbon emissions, with the rest from the operational heating and power. With a target to reduce emissions by 75% through operational carbon reductions, the embodied carbon becomes much more significant at up to 60% of the whole life emissions.

It is therefore crucial that the embodied carbon of new building fabrics designed for 2025 standards are understood, to ensure that any savings in operational carbon are not offset by the introduction of a building fabric with high embodied carbon.

 

Time for Timber

When we factor embodied carbon into the zero-carbon journey, timber really comes into its own. As the only naturally renewable building material, timber build solutions are undeniably the most sustainable form of construction. Using a timber frame build system for a 2021 new-build home reduces the embodied carbon by around five tonnes, compared to a masonry construction home of the same fabric performance. This carbon saving will undoubtably increase as the building fabric performance is increased to achieve 2025 levels.

Timber frame homes are more environmentally friendly during the build, when the building is in use and throughout its lifetime. Timber can also lower or offset its embodied carbon thanks to sequestration – absorbing atmospheric CO2 while the tree is growing and storing it until the timber is incinerated or goes to landfill at the end of its use. Around one tonne of CO2 is stored in every m³ of timber.

While we’ll continue to campaign for the legislation of embodied carbon, many organisations will reach the conclusion that they need to consider the full process to meet their corporate sustainability goals. In recognition of this, we’re working with our customers to help measure the sequestered and embodied carbon for all our build systems.

Through experience, measurement, and science, we can demonstrate that timber offers an ideal solution to achieve true net zero carbon targets. One day, all homes will be built this way.

The growth of timber frame is changing long-established practices within housebuilding as the construction industry embraces the idea of off-site manufacture. This approach is due mainly to the fact that offsite manufacture means a huge reduction in the site-based activities that define a traditional building firm. The reduction in on-site activity means that, once the building’s foundations are installed, erection of the main structure follows very quickly, typically taking only two or three days to complete. New timber-framed homes can therefore be brought to market at a much faster rate than is possible with traditional brick-and-block. Crucially, this also has the effect of extending the building season which, traditionally, slows significantly during the winter period. Housebuilders can therefore be more productive throughout the year if they build with timber frame.

After land prices, the two biggest cost factors in housebuilding are time and labour. Timber frame scores significantly on both counts since off-site manufacture reduces not only the erection time on site but also the amount of traditional building skills required. The factory processes employed in the manufacture of timber frame cassettes can be largely automated, unlike traditional site-based building trades.

Structural timber technology addresses many government concerns associated with the procurement of housing – including environmental impact and energy efficiency, as well as speed of construction and cost. The materials that go into a timber frame system are generally more sustainable and more energy efficient than traditional masonry.

For example, West Fraser’s oriented strand board, SterlingOSB Zero, is one of the most widely-used components of UK timber frame systems. OSB is an essential component of all timber framed panel systems and a major contributor to their growing popularity. SterlingOSB Zero is manufactured in Scotland from home-grown forest ‘thinnings’ (slender, immature trees harvested as part of sustainable forest management) while its zero-added formaldehyde (ZAF) formula is designed specifically for safer construction and healthier buildings.

Besides ‘traditional’ timber frame construction, newer timber-based off-site technologies, such as cross-laminated timber and structural insulated panel systems (SIPS), are strengthening timber’s share of the housebuilding market. The benefits of these systems, being comparably lower energy intensive and emission producing in their manufacture and possessing greater thermal efficiency in their use, is helping to support their specification in the timber frame market.

The SterlingOSB Zero range from West Fraser                                                                                                                     

Manufactured using renewable heat from on-site biomass boilers, West Fraser’s SterlingOSB Zero is a sustainable, low-energy product with excellent physical performance characteristics. West Fraser’s OSB portfolio comprises SterlingOSB Zero 3, SterlingOSB Zero Tongue and Groove, and SterlingOSB Zero StrongFix.

 Work has begun to transform a vacant brownfield site into a landmark, 30 home timber frame housing development – providing much needed affordable properties in Leeds.

 The scheme will deliver a total of 14 one bedroomed apartments, ten two bedroomed houses and six three bedroomed homes – two of which will be located on a satellite site, replacing two old properties that were previously demolished.

The homes to be built at Leeds Meynell, in Holbeck, will be 100% affordable and constructed in less than nine months, with the first residents expected to move in by early summer 2022.

 They will be built using an innovative timber frame construction process, that involves constructing elements of the properties offsite – in a factory-controlled setting – before transporting them to site for assembly. The method uses the same materials, standards and codes as conventionally built homes but the controlled plant conditions ensure the process is completed more quickly than a traditional build.

 They will be constructed using a ‘Fabric first’ approach – which involves maximising performance of the materials and components that make up the very fabric of a building. This will help to achieve a key objective of the project, which is to ensure energy efficiency, lower fuel bills and tackle the fuel poverty problems that some Leeds City Council tenants face. The eco-friendly scheme will also support the council’s commitment to reduce the city’s direct carbon emissions to net-zero by 2030 and make Leeds a greener, fairer and healthier city.

 The project is being delivered through Leeds City Council’s Housing Growth Programme (CHGP), which aims to build around 1500 new, high-quality social housing units over the next five years. Once completed, the new homes will be managed by the council and will become part of its affordable housing stock,

 Mick Holling, Managing Director with United Living New Homes North, said: “Leeds is a thriving and growing city which needs new, good quality housing to meet demand. We look forward to playing a central role in regenerating this area of Leeds and creating much-needed new homes for local people.

 “The timber frame sector is transforming the way new homes are built. It offers a comprehensive, energy-efficient and low carbon solution for social housing that is high-quality, affordable and easily accessible and adaptable”.

 Councillor Helen Hayden, Leeds City Council’s Executive Member for Infrastructure and Climate, said: “One of Leeds’ biggest priorities is to provide enough housing to meet the needs of a growing population. This is why we have developed our programme to build 1,500 new affordable homes over the next 5 years; all of which need to be high quality and accessible. Not only will this scheme positively contribute towards this ambition, it will also help us achieve our climate targets by providing people with energy efficient, low carbon homes.

 “I look forward to following the progress of this scheme and welcoming our first residents later this year.”

 As the principal contractor for the development, United Living will partner with Leeds City Council and William Saunders Architects.

Timber frame specialist, Blue Sky Property Services, of Norfolk, is always mindful of the environmental impact of its building and renovating projects.  This is certainly true of the conversion of an old engineering unit into a luxury two double bedroom eco holiday rental being built in the Norfolk countryside.

“We always specify West Fraser products as they are easy to use and are produced with the environment in mind.  We used CaberShieldPlus on the first floor as we didn’t need to worry about leaving it exposed while we were building.  The non-slip textured finish is not only safe; as the waterproof coating is permanent, it means there’s no plastic to throw away!” said James Carter, Director of Blue Sky Property Services.

All West Fraser panel products produced in the UK are net carbon negative and manufactured in mills that have obtained the coveted environmental ISO 14001 accreditation. Responsibly sourced, the panels are FSC certified and created from locally grown timber, cutting embodied carbon from transportation. Samples of SterlingOSB Zero, and West Fraser’s other construction panels, can be ordered on the website.
