ACCOYA®
Radiata Pine
WOOD TO CHANGE THE WORLD
Accoya wood is made by Accsys at its Arnhem plant in the Netherlands.
Accsys transforms fast-growing, certified sustainable wood into Accoya wood through its patented acetylation process.
The result is a high-performing product with sustainability credentials that exceed those of man-made and heavily carbon-polluting alternatives.

1
Hyrdoxyl Groups – Hydroxyls are hydrophilic (attract water), causing cellulose to swell (and shrink when subsequently dried) and become more susceptible to attack by biological organisms
3
Acetylation – Reaction of wood with acetic anhydride (concentrated acetic acid) at high temperature to increase the moisture-resistant acetyl groups' level.
2
Acetyl Groups – Wood cellulose contains a small number of naturally occurring acetyl groups, which are hydrophobic (repel water). There are insufficient acetyls in natural wood to provide durable, stable performance.
4
Accoya Acetylated Wood – Contains the same constituents as natural wood, just at enhanced levels. There are now more moisture-resistant groups and less moisture-binding groups. This delivers high performance through increasing dimensional stability and enhanced biological durability.
