SterlingOSB Zero family uses a methylene diphenyl diisocyanate (poly-urethane MDI) resin to bind the thousands of strands that make up each board. This pMDI binder cures at a lower temperature than UF/MUF resins so less heat energy is consumed during manufacture. It is also safer to produce since pMDI resin uses water as a catalyst in the curing process rather than the ammonium nitrate require to harden UF/MUF resins.

SterlingOSB Zero is made from forest thinnings taken from sustainably managed forests. All

promotes wood benefits to see the timber industry

Södra, the sustainable timber supplier is supporting Swedish Wood and Wood for Good’s Wood Co2

ts less campaign. The

campaign, which launched last month, is an industry-wide initiative developed for UK timber associations and member companies. Its aim is to promote the use of all wood products as low carbon materials and illustrate how using wood can help reduce CO2

in the

atmosphere and contribute to slowing climate heating. Jeremy English, Södra Sales Director, said: “It’s heartening

rallying around one common goal: to raise awareness of timber’s environmental benefits. It’s a brilliant campaign and as a member of both Swedish Wood and Wood for Good – and a passionate advocate for the benefits of building with responsibly-sourced timber – we’re of course proud to support it.” Four key facts form the staple of the Wood Co2

ts less campaign:

• Using wood from sustainably managed forests instead of other materials is one of the simplest ways to reduce the carbon

emissions generated by the construction industry. • Wood captures and stores carbon for the life of the wood product.

• Using wood instead of other materials saves CO2


both through the carbon captured and stored in the wood product and the avoidance of using alternative CO2

• Using wood in construction is a cost-effective solution to carbon capture.

“To those in the industry, the benefits of building with timber are no secret,” explains Jeremy. “But part of this campaign’s aim is to reach those beyond the timber industry. Unfortunately, many out there still believe that cutting down trees must be bad for the environment. In reality, if timber is responsibly sourced from suppliers like Södra, then this couldn’t be further from the truth. For example, for every tree we cut down we plant another three in its place.”

-intensive materials.

The facts certainly bring Jeremy’s comments sharply into focus. Between 2005 and 2015 the average annual sequestration of carbon in forest biomass reached 719 million tonnes in the European region, corresponding to about 9% of the region’s net greenhouse gas emissions (according to the United Nations). The Committee on Climate Change has also said that using wood in construction to displace high-carbon materials such as cement and steel is one of the most effective ways to use limited biomass resources to mitigate climate change. “It’s a well-known fact that cement-making is one of the world’s biggest carbon emission culprits, accounting for 8% the global total,” concludes Jeremy. “Alternatively, responsibly managed forests have always been the earth’s air cleaners and will continue to be so forever. And a by-product of responsibly managed forests? High-quality, sustainable timber; timber that has already taken from the air and locked away decades’ worth of harmful CO2.”
