Accoya - heard of the Accoya tree?
So why have you never heard of the Accoya tree? Well that’s because they don’t exist.
Accoya starts life as a fast-growing pine tree (Pinus radiata) grown in managed forests. The pine tree is harvested once it reaches maturity at around the 30 year mark. It’s at this point its journey isn’t the same as other timber. We introduce the raw timber to a modification process as a plank or beam, the so-called acetylation process using acetic acid. This process creates extremely dimensionally stable and durable wood.

Accoya® is the brand name of this modified wood.
Accoya wood is highly rot-resistant and very stable across varying climates. Containing no toxic substances as the process simply increases the levels of already present elements within the molecular structure of the wood.
Every piece of Accoya has been modified through to its core, providing the same performance and protection no matter how the wood is cut, planed, drilled, shaped, or more…
This makes Accoya ideal for many applications including window frames, doors, façades, cladding, decking, all without the use of preservatives. Accoya wood is Class 1 durable and surpasses even the most durable old growth tropical hardwoods The production of Accoya is based on the process of wood acetylation. Scientists have proven that this modification process is an incredibly effective method to improve the technical properties of wood.
How it works
Wood acetylation works by changing the cell structure of the wood whereby the cell walls are “blocked” for moisture absorption. This modification reduces the wood’s ability to absorb water in the cell walls by about 80%, greatly improving dimensional stability, resulting in Accoya requiring less maintenance.
The change in cell walls means that insects and fungi do not recognise Accoya wood as a food source and therefore do not attack. Perfect for those parts of the world with termites or other wood eating critters.
Durable windows & doors
Accoya wood is Class 1 durable even in very challenging use environments. The wood is modified right through to the core. Each batch of Accoya is checked for quality by taking 19 samples in Accsys’ laboratories.
Accoya wood is Cradle to Cradle Gold CertifiedTM. This has been awarded to Accoya because it is fully circular. The process adds nothing to the wood that is not naturally present. An incredible sustainability story is shown in the life of Accoya wood. Supported by a 50 year above ground and 25 year in-ground warranty, effectively giving forests time to regrow across the total life cycle of Accoya, where other timbers have a shorter use life vs time taken to grow into logging maturity.
How we get this unique timber
Accoya long life modified wood has become the timber industry benchmark for performance and sustainability. No other timber can offer this combination of stability, durability and versatility. This modified wood is sustainably sourced with FSC® certification and it has minimal environmental impact throughout its entire life; from production, through its use, right the way to the end of its life.
