Accoya

Highly durable acetylated wood with no biocides, for outdoor use and façades.

Description

Acetylated wood produced by Accsys, with a plant in Arnhem (Netherlands) and a British parent company. Acetylation modifies radiata pine wood with acetic anhydride, raising its dimensional stability and durability to classes reserved for tropical woods, with no added biocides. It is used in exterior joinery, façades, decking and walkways, with decades-long guarantees for outdoor use. Environmental documentation is yet to be verified for the Spanish market.
