Accoya Windows & Doors

Brilliance for generations to come

Accoya Windows and Doors redefine what’s possible with natural timber joinery. Manufactured from acetylated Radiata Pine, Accoya’s cellular structure is permanently enhanced to resist moisture movement, decay, and insect damage. This results in joinery that retains its strength, shape, and finish for decades, offering long-term reliability with minimal maintenance.

Unlike traditional timbers that warp or swell with changing conditions, Accoya remains stable and smooth-operating, ensuring that windows and doors continue to open and close effortlessly over time. The wood’s stability also extends the life of coatings and paints, reducing maintenance costs and enhancing the longevity of finishes in both residential and commercial projects.

Accoya’s environmental credentials are equally impressive. Made from sustainably sourced FSC® certified timber, it is non-toxic, 100% recyclable, and carries a low carbon footprint. Its 60-year service life expectancy in exterior use makes it one of the most sustainable and high-performing choices available for architectural joinery. Duce Architectural Timbers supplies Accoya Windows and Doors for projects across Australia, combining craftsmanship, technical precision, and dependable service.
