Accoya wood windows are engineered to withstand challenging conditions. Thanks to their improved dimensional stability and resistance to swelling, shrinking and rot, Accoya outperforms many conventional timbers. This is achieved through a natural acetylation process that permanently modifies the wood, enhancing its durability and making it highly resistant to moisture and decay.

As a result, Accoya windows maintain their shape, appearance and performance even in coastal, high-humidity or harsh weather environments, providing  long-lasting beauty and reliability.
