Accoya® can be left natural or finished to suit any design, providing lasting performance in any climate or application.

WHY ACCOYA® WINDOWS AND DOORS?
Thanks to its exceptional dimensional stability, Accoya® windows and doors resist swelling, shrinking and warping — so frames continue to open and close effortlessly all year round, season after season.
Their highly stable structure also provides an ideal surface for coatings, meaning finishes stay looking pristine for longer and require far fewer repainting cycles than traditional timber.
Accoya’s natural thermal insulation helps keep homes cosy and reduces energy costs, while the superior durability backed by a 50 year above-ground warranty gives you decades of reliable performance.
