Accoya Joinery
Natural Timber Craftsmanship.
Engineered to Last.
Accoya® joinery supplied by Britton Timbers brings together the authentic warmth of real wood with advanced performance engineered for Australian conditions. Through its unique acetylation process, Accoya® timber resists decay, warping and movement — making it ideal for external doors, window frames and high-spec joinery where durability and finish matter.
- Exceptional durability & warranty – With a 50-year above-ground warranty on joinery applications, Accoya® gives you long-term peace of mind, even in demanding climates
- Superior stability – Accoya® joinery is highly dimensionally stable, so frames and doors open and close smoothly year-round, even in coastal humidity or intense sunlight
- Low maintenance, lasting finish – Thanks to its stable nature, coatings adhere and last longer on Accoya®. That means fewer repaint/reseal cycles and less upkeep in the Australian environment
- Sustainably sourced & environmentally responsible – Manufactured from FSC® certified forests and processed without toxic preservatives, Accoya® supports green building practices and reduces long-term environmental impact.
Backed by a 50-year above-ground warranty, Accoya® joinery delivers long-term confidence for doors, windows and exterior applications exposed to Australia’s harsh conditions. You can rely on proven performance that stands the test of time.
Accoya® provides an exceptional surface for coatings and stains, ensuring a flawless, lasting finish. Paints and stains adhere more effectively and maintain their colour longer — giving joinery a premium look that endures under Australia’s intense sun and temperature extremes.
Thanks to its remarkable stability and resistance to weathering, Accoya® joinery requires minimal maintenance over its lifetime. Fewer repainting cycles, less swelling and smoother operation mean reduced upkeep and more time between maintenance intervals.
Accoya® joinery is engineered to stay true to form. Doors and windows open and close smoothly year-round without sticking, warping or gaps — even in coastal or humid environments where traditional timbers struggle.
Accoya wood joinery last a lifetime
What is Accoya Wood?
Accoya modified wood has become the lumber industry benchmark when it comes to performance and sustainability. No other wood offers the same combination of durability, stability and versatility. Sustainably sourced, and with a low total lifetime carbon cost, Accoya actively contributes to a circular, bio-based economy and is one of the few truly sustainable building materials.
Accoya is produced in both Kingsport, USA and Arnhem, the Netherlands. In this video, we take a closer look at the groundbreaking science behind Accoya wood. Through a precise acetylation process using acetic anhydride, combined with just the right heat and pressure, we increase moisture-resistant acetyl groups and reduce the water-attracting hydroxyl groups. This unique patented technology turns fast-growing, sustainable wood into an ultra-high performance building material.
