Accoya® – An Innovation in Wood
Accoya® is the world’s leading high technology long life wood. Created via acetylated wood modification, using sustainably grown timber, the Accoya® process is non-toxic. It enables nature and creates a modified wood that matches or exceeds the durability, stability and beauty of the very best tropical hardwoods.
Acetylation is a process which increases the amount of 'acetyl' molecules in wood, thereby changing its physical properties. The process protects wood from rot by making it "inedible" to most micro-organisms and fungi, without - unlike conventional treatments - making it toxic. It also greatly reduces the wood's tendency to swell and shrink, making it less prone to cracking and ensuring that, when painted, it requires dramatically reduced maintenance.
Accoya opens up new opportunities
A new world of high performance wood, sustainable, low maintenance products – including windows, doors, decking, cladding and glulam structural beams – is opened up by Accoya wood. Accoya wood is guaranteed for 50 years in exterior use and 25 years when used in the ground.
By significantly enhancing the durability and dimensional stability of fast-growing and abundantly available FSC or PEFC certified wood, Accoya® wood provides compelling environmental advantages over slow-growing hardwoods (which are often unsustainably sourced), woods treated with toxic chemicals, and non-renewable carbon-intensive materials such as plastics, metals and concrete.
Extensive laboratory and field testing by leading institutes around the world (including in New Zealand, USA, UK, Sweden, Malaysia, Indonesia, Russia, the Netherlands and Japan) has shown the performance of Accoya wood to be extremely reliable.
