Accoya sustainable wood

Long life rot-resistant wood

Accoya is a revolution in modified dimensionally stable wood, delivering remarkable levels of performance. A product made to last.

The benefits of Accoya mean that timber projects can now be designed with absolute confidence. Accoya is stable wood and warrantied. Our quality mark signals the Accoya difference.

Why Accoya

Accoya wood is made by Accsys at its plant in Arnhem, in the Netherlands. Accsys transforms fast-growing, certified sustainable wood into Accoya wood through its proprietary acetylation process.

The result is a high performing product with sustainability credentials that exceed those of man-made, intensely resource depleting and heavily carbon-polluting alternatives.

This gives the world the choice to build sustainably, offering new opportunities for the built environment.
