USE TREATED TIMBER IN YOUR NEXT PROJECT – THE SUSTAINABLE CHOICE

The environmental benefits of using wood in construction are compelling . Managed properly and from certified sources , trees provide a renewable material that absorbs and stores ( sequesters ) carbon . At the end of its life timber can be reused in a cascading process of uses , recycling or recovery of energy .
Enhancing durability and performance
Using more wood is great – however in terms of longevity or performance , some species may need additional help . By using industrially applied preservative treatments or wood modification , the service life of less durable softwoods can be improved – reducing pressure on the more naturally durable , scarcer and higher value species . And flame retardants for timber , which reduce the surface spread of flame , heat and smoke release in a fire situation , provide vital extra time for a safe escape where required .
The additional energy input of pre-treated wood production is comparatively low . The treatment industry is highly regulated and today ’ s products and processes are better targeted towards the factors we wish to control with less impact on the wider environment .
Ensuring fitness for purpose
Not-for-profit and independent , the Wood Protection Association ( WPA ) acts as a technical and advisory body – providing free guidance to specifiers , contractors , engineers and architects on the best ways to ensure wood is fit for its intended purpose .
