Accoya wood is chemically modified timber. Natural softwood is put through an acetylation process to enhance its characteristics. Accoya is durable, sustainably sourced, and thermally efficient. Its superior strength and attractive aesthetic make it the perfect material for creating bespoke windows and doors.
The Accoya wood acetylation process
Wood acetylation is a scientifically proven method of improving the properties of natural timber. During the acetylation process, the softwood is treated with acetic anhydride. This alters the cell structure of the softwood, transforming the naturally occurring free hydroxyls into acetyl groups.
Once the process is complete, the Accoya wood is harder, more durable, and more resistant to rot. Its capacity to absorb water is reduced by up to 80% making it far more dimensionally stable. Furthermore, the compositional alteration that occurs means that fungi does not recognise Accoya as a wood and will not attack it. The process also makes Accoya indigestible to insects, eliminating the risk of infestation.
