Ultra-High Performance Sustainable Wood
Tried and Tested in the UKTrusted since 2007 by architects, manufacturers and homeowners alike. With more than 500,000 landmark projects worldwide, Accoya is redefining the potential for wood.
What is Accoya Wood?
Accoya modified wood has become the benchmark in the timber industry for 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 available.
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 carefully controlled heat and pressure—we increase the moisture-resistant acetyl groups and reduce the water-attracting hydroxyl groups. This unique, patented technology transforms fast-growing, sustainable wood into an ultra-high-performance building material.
