Accoya® wood is a modified wood.  Manufactured using a non-toxic treatment and timber sourced from sustainable forests, Accoya® wood has properties that match those of the best tropical hardwoods.

Accoya® wood is modified all the way through, not just at the surface layer like many alternative treatments. This modification technique has two key advantages:

  • Users of Accoya® wood can have absolute confidence in the wood's durability in a way that has not previously been possible. Accoya® wood's durability is validated in a laboratory after the process has taken place. Using an array of sophisticated and proven analytical techniques, Accoya® wood's producers ensure that every batch is of consistent quality and reaches the highest possible performance standards.

  • When Accoya® wood is cut or jointed there are no exposed non-acetylated surfaces in any dimension. This completely negates the need to apply additional chemical preservatives on-site, as is necessary with unmodified or envelope-treated woods.


All exterior applications including windows, doors, decking and cladding.

Accoya®  wood's high strength to weight ratio also makes it suitable for challenging external applications, such as road traffic bridges.
