Accoya® modified wood cladding
Accoya®
With its unrivalled performance benefits, Accoya® is ideal for projects where a flawless painted finish and clean, crisp lines are desired. Accoya® is created by modifying Radiata Pine, through the use of a non-toxic acetylation process. This uniformly attractive, consistently durable and dimensionally stable product is fully sustainable and will last a lifetime. In addition to standard Accoya®, we offer Accoya Color Grey, a distinct product manufactured to achieve a consistent grey colour throughout the board. While performance remains the same, Accoya Color Grey provides a uniform grey appearance from day one, removing the need to rely on natural weathering to achieve this look.

Origin
New Zealand
Modified timber
Yes. Radiata Pine is modified through a non-toxic acetylation process to create a high-performance timber with superior stability and durability.
Grade
Accoya® wood is available in four grades (A1, A2, A3 and B). We supply only the cleanest grade – A1.
Weathering
Uncoated Accoya® is a cream/light straw colour, which will take on a silvery-grey appearance when left to weather naturally. Accoya Color Grey is grey throughout from initial manufacture, providing a consistent appearance from installation.
Sustainability
Sustainably sourced from well managed forests (FSC® or PEFC certified).
SiOO:X coating
Not suitable for coating with SiOO:X.
Durability
Outstanding durability (Class 1 - 3 BS EN 350-2) due to modification. All Accoya products come with a 50 year Accoya warranty as standard.
Paint coating
Accoya® is the ultimate surface for factory-coating with opaque or translucent paint. Virtually no shelling, cracking, checking or fissuring will occur. Coatings can be expected to last up to three times longer than on unmodified timbers, substantially reducing maintenance requirements. Accoya Color Grey is not suitable for paint coating, as the colour is integral to the timber and designed to be left uncoated.
Appearance
Primarily clear of knots with little figuring. Most commonly supplied painted due to Accoya’s exceptional coating performance. Accoya Color Grey has a consistent grey colour throughout the board, designed to last for the lifetime of the product.
Density
Medium - classified by BS EN 350-2 as approximately 592 Kg/m³ at a moisture content of approximately 8%.
Fire retardant coating
Accoya® can be treated with fire retardant, but Accoya Color Grey is not suitable for fire retardant treatment.
Application
Suits projects where a flawless painted finish and clean, crisp lines are desired. Various lengths, including fixed lengths, available from stock.
Stability
Excellent stability; swelling and shrinkage is virtually eliminated in Accoya®.

Expert View
The dimensional stability properties of Accoya® are unrivalled, making it the ideal substrate for low maintenance, decorative paint finishes. Boards display subtle figuring with very few knots, resulting in a clean and contemporary aesthetic. Our RW119 Performance profile makes Accoya® a viable option for a wider scope of projects.

What is the difference between Accoya® and Accoya Color Grey?
Accoya® and Accoya Color Grey offer the same performance benefits, including durability, stability and long service life.
The key difference is appearance. Standard Accoya has a pale, natural tone that will weather over time to silver/grey and is generally supplied factory-coated with opaque or translucent paint.
Accoya Color Grey is pigmented with colour throughout the board, providing a consistent grey appearance from installation without the need for coatings or reliance on natural weathering. Ideal for projects where a consistent grey finish is desired from the outset, without ongoing maintenance or coating requirements.
