Accoya is a high-performance wood made using a special acetylation process that changes the wood at the cellular level. Unlike surface treatments or heat modification, this process changes how much water the wood absorbs, which greatly reduces swelling, shrinking, and movement.
The result is real wood that stays stable, is highly durable, and lasts a long time. Accoya resists rot, keeps paint and coatings on much longer than regular wood, and works well even in tough climates like coastal or humid areas.
You can cut, fasten, and install Accoya just like any other wood. However, it performs more like synthetic materials or tropical hardwoods. Accoya gives you the natural look and feel of wood, along with the reliability of an engineered product.
Accoya Decking
Accoya decking stays stable where it counts. Outdoor deck boards face constant changes from wet and dry conditions, sunlight, and temperature shifts. Accoya helps keep boards flat, gaps even, and the structure strong over time.
Accoya is as durable as tropical hardwoods but is lighter and easy to work with. Its surface takes stains and coatings evenly and keeps them looking good for longer, so you don’t have to maintain it as often.
If you’re an architect or builder looking for a sustainable option instead of Ipe or composite decking, Accoya gives you top performance and still looks and feels like real wood.
Accoya Exterior Siding
Accoya cladding stays stable over time, making it a good choice for vertical uses where you want precise lines and a lasting finish. Less movement means tighter lines, cleaner shadows, and joints that stay even.
Because Accoya doesn’t take in much moisture, it helps prevent warping and cupping. Its strong durability means it lasts a long time, even in tough weather. Paint also lasts much longer on Accoya, so it works well for both natural and painted looks.
For high-performance facades, rainscreens, and siding, Accoya gives you the natural warmth of wood along with the reliability of an engineered product.
