Accoya is not a species of wood. It’s a specially modified timber known for its outstanding performance. Made from fast-growing, sustainable pine, it goes through a patented acetylation process that makes it one of the most durable, stable, and sustainable woods available. It delivers the beauty of real wood without the usual problems of swelling, warping, or rot.
As an accredited Accoya manufacturer, Foden Joinery can craft bespoke windows and doors from this high-performance material. We can also supply Accoya timber direct to customers for their own projects.

Accoya is real wood that’s been engineered to perform better. It’s made by modifying sustainably sourced timber all the way through, not just at the surface. This process changes the wood on a cellular level, making it extremely durable, stable, and long-lasting.
Accoya is rated Class 1 for durability – the highest rating possible. It outperforms even the best hardwoods like oak or teak. It won’t swell, shrink, twist, or warp as temperatures or humidity change. That means windows and doors made from Accoya stay smooth and easy to operate, with paint or varnish finishes that last far longer.
Accoya is also non-toxic and eco-friendly. It’s made from renewable wood, contains no harmful chemicals, and is 100% recyclable. It’s natural wood, built to last.
Exceptionally Durable
Accoya comes with a 50-year warranty above ground and 25 years below ground or in contact with water. It’s rot-proof and insect-resistant, making it ideal for external joinery that must stand up to the British weather year after year.
Highly Stable
Accoya doesn’t warp, swell, or stick. Frames stay true through every season, so windows open and close easily and doors fit perfectly. Its stability also means paint coatings last longer, needing less maintenance over time.
Low Maintenance
Accoya resists rot and moisture, so it doesn’t need frequent treatment or sealing. Paint adheres better and stays intact, keeping your joinery looking fresh for longer with less effort.
Sustainable
Accoya is made from certified sustainable forests and uses a non-toxic modification process. No harmful chemicals are added, and all by-products are reused. The timber is long-lasting, recyclable, and carbon negative over its lifecycle. It’s the responsible choice for modern homes.
Beautiful Finish
Accoya combines performance with natural beauty. It has a smooth, consistent grain and can be painted or stained any colour. Its light tone takes coatings evenly, and because the wood doesn’t move, the finish stays sharp for years.
Being an Accoya Approved Manufacturer means Foden Joinery meets strict quality standards for working with this specialist timber. Our team is fully trained in its use, ensuring precise joinery and a perfect finish every time.
We can supply and fit bespoke Accoya windows, doors, and gates, or provide the timber direct if you prefer to handle the build yourself.
