Accoya wood, produced under the Accoya trademark, is acetylated radiata pine. Acetylation refers to a process in which wood is treated with acetic anhydride. The treatment primarily affects the wood’s dimensional stability and its bioresistance, i.e. rot resistance. Accoya is naturally renewable, and it is also more durable than many threatened tropical hardwoods. Accoya has been granted numerous environmental certificates, including the Nordic Swan Ecolabel.
Advantages of Accoya covers:
- Durability: Accoya® wood is ideal for demanding conditions where the wood is continuously exposed to moisture and heat. Accoya® is dimensionally stable even when wet: it does not swell or bend.
- Dimensional stability: Thanks to its excellent dimensional stability and hardness, the wood requires less maintenance and does not need to be treated often during the product’s lifetime. Accoya® wood expands and shrinks 75% less than regular wood.
- Perfect for coating: The coating lasts 3 to 4 times longer.
- Sustainably sourced: All Accoya® wood is procured from well-managed forests that meet environmental requirements and which have been granted FSC, PEFC or other regional certification.
- Non-toxic: Accoya® wood is non-toxic, which means the toxins that are normally associated with wood treatment are not released into the environment with Accoya wood.
- Continuously available: Made from abundantly available, fast-growing source species, such as Monterey pine (Pinus radiata).
