Sustainable high performance wood

Ideal for windows, doors, cladding, decking and many more applications

Accoya® wood is a high performance wood. Created from sustainably-sourced wood, Accoya® undergoes a proprietary, non-toxic acetylation process that permanently modifies the wood to the core.

The result: an environmentally friendly solid wood with durability, dimensional stability and beauty that matches or exceeds even the best tropic hardwood.

Accoya® wood is sourced from sustainable sources, including FSC® and has class leading environmental credentials such as Cradle to Cradle™ Gold certification by the highly prestigious McDonough Braungart Design Chemistry (MBDC) organization.

Accoya® wood is perfect for demanding applications such as windows and doors, where it is important that tolerances are tight yet regardless of the conditions, they open year round. Accoya® is perfect for siding where wood’s natural beauty is desired, but sustainability and high performance are of the utmost importance. In decking, where it is important that boards do not warp, twist, bow split, Accoya® is up to the challenge.

Features & Benefits

Extensive laboratory and field testing by leading institutes around the world (including in New Zealand, USA, UK, Sweden, Malaysia, Indonesia, the Netherlands and Japan) has shown the performance of acetylated wood to be extremely reliable. Accoya® wood has been thoroughly tested for dimensional stability, durability, paint retention and in-ground conditions to ensure optimal performance. Indeed, it is so reliable that for many years it has been – and continues to be – used by scientists as the benchmark against which other treatments and modifications are measured.
