The science behind Accoya windows and doors
Accoya wood is the result of more than 80 years’ research and development that has brought together a long-established and extensively proven wood modification technique. As part of them process, Accoya undergoes a leading-edge proprietary technology, which is known as non-toxic acetylation.
