What Is Accoya Wood?
Exceptional Timber Solutions for Commercial & Residential Applications
Accoya wood is a structurally-modified timber product that offers superior durability and strength. Through a unique acetylated process using acetic anhydride and real-world testing, Accoy timber supplies are known to withstand varying environmental conditions.
It is manufactured and tested not to visibly swell, shrink or distort and can be expected to last a lifetime in both above-ground and in water conditions, making it the ideal choice for even the most extreme climate.
The acetylation process works by altering the wood’s chemical structure, making it:
- Resistant to moisture absorption
- Highly stable with minimal movement
- Virtually immune to fungal decay
- Naturally resistant to insect attacks
Unlike traditional timber treatments that rely on chemicals to protect the wood, Accoya’s modification process creates a material that’s naturally resistant to the elements. This means it maintains its strength and appearance for decades!

The Benefits Of Accoya Timber
The Accoya Timber Difference
Exceptional Durability
Accoya timber achieves the highest durability classification (Class 1), outperforming even naturally durable hardwoods. This translates to a 50-year above-ground warranty and 25-year in-ground warranty, giving you confidence in your investment.
Outstanding Dimensional Stability
With up to 80% reduction in swelling and shrinkage compared to untreated timber, Accoya maintains its shape and fit regardless of humidity changes or exposure to water. This means less maintenance and longer-lasting results for your project.
Insect & Rot Resistance
The proprietary, non-toxic acetylation process makes Accoya timber indigestible to a wide range of insects and highly resistant to fungal decay. This makes it particularly valuable in areas prone to termites and other wood-boring insects.
Natural Beauty & Versatility
Despite its advanced modification, Accoya retains the natural beauty and workability of timber. It can be machined, finished and painted just like traditional timber, giving you complete design flexibility.
Reduced Maintenance Requirements
Accoya’s stability and durability mean less frequent maintenance is required. Coatings last up to twice as long on Accoya compared to untreated timber, reducing lifetime costs and effort.
