Accoya decking is real timber, reimagined. Through a proprietary acetylation process, Accoya transforms timber at the molecular level, which permanently alters the wood’s cell structure, dramatically reducing the impact of water and improving long‑term stability. This innovation delivers the world’s best-performing real timber deck boards - minimising swelling, cracking, splitting, and splintering.
It’s this performance that underpins Accoya’s transferable 50‑year above‑ground warranty for boards installed 200 mm and above; boards under 200 mm are covered by a 25‑year warranty (maximum span 400 mm).
Why Accoya?
The Decking Collection by Accoya delivers the warmth, texture, and character of natural wood, without the usual maintenance headaches. Made from responsibly sourced, FSC®‑certified timber, Accoya combines sustainability with advanced engineering to create a product that performs reliably year after year—without chemical preservatives or surface treatments.
Its exceptional dimensional stability means boards stay flatter and more consistent over time, helping maintain clean lines, tight gaps, and a premium finish long after installation.
What Makes Accoya Different?
- 100% Real Wood: Responsibly sourced timber, precision-engineered for performance.
- Natural Appeal, No Compromise: Warmth, texture, and character of timber -without drawbacks.
- Two Stunning Choices:
- Slate Grey: Fully infused colour throughout the board for rich, lasting tone. No recoating or refinishing needed.
- Natural: Ages gracefully to a unique silver-grey patina. Prefer colour? Coat the boards in a colour of your choice for a custom finish that lasts.

Performance You Can Trust
Accoya decking resists rot, fungi, and wood-destroying organisms like termites. Maintenance is minimal - just clean with water and mild detergent once or twice a year. No coatings required. Even uncoated, Accoya retains its warranty and turns a beautiful natural grey over time.
Plus, have peace of mind, guaranteed. Every Accoya deck board is backed a strong warranty: 50 years for decking 200mm above ground and high, or 25 years for ground clearance under 200mm (with a recommended span of 400mm). You can trust Accoya to deliver lasting performance in any environment.
