Accoya® timber is produced by Accsys in its factory in Arnhem in the Netherlands. Accsys transforms certified sustainable, fast growing timber into Accoya® through its proprietary acetylation process.
Acetylation applies a modification at the molecular level which changes the structure of the timber itself, improving many of its performance characteristics, above all natural durability and dimensional stability. Modification of the timber (chemical, thermal or impregnation) such as acetylation, improves timber’s physical, mechanical or aesthetic properties. This process produces a material that can be disposed of at the end of the life cycle of a product without presenting greater environmental risks than those associated with the disposal of natural timber.
