What is Accoya Wood?
Accoya modified wood has become the lumber industry benchmark when it comes to performance and sustainability. No other wood offers the same combination of durability, stability and versatility. Sustainably sourced, and with a low total lifetime carbon cost, Accoya actively contributes to a circular, bio-based economy and is one of the few truly sustainable building materials.
Accoya is produced in both Kingsport, USA and Arnhem, the Netherlands. In this video, we take a closer look at the groundbreaking science behind Accoya wood. Through a precise acetylation process using acetic anhydride, combined with just the right heat and pressure, we increase moisture-resistant acetyl groups and reduce the water-attracting hydroxyl groups. This unique patented technology turns fast-growing, sustainable wood into an ultra-high performance building material.
