Accoya

Accoya stands as the global leader in high-performance wood. Our patented modification process enables wood to withstand the harshest exterior elements while enhancing its natural beauty, strength, and character.

Powered by proven acetylation science, Accoya wood is permanently transformed at the cellular level, creating a material that is virtually unaffected by water uptake. This results in exceptional dimensional stability, durability, and resistance to rot and decay.

Backed by a leading warranty—50 years above ground and 25 years in ground or freshwater—Accoya is FSC® accredited, Cradle to Cradle Certified® Gold, and the only construction material worldwide to achieve C2C Platinum™ for Material Health. Setting the benchmark for high-performance building materials, Accoya delivers exceptional longevity, sustainability, and confidence in every application.
