Frequently Asked Questions

What is Accoya wood made from?
Accoya wood is made from radiata pine trees. These are sourced and taken to our production facilities in the Netherlands where they undergo a modification process, more specifically known as Acetylation. This process turns the radiata pine wood into the worlds most stable wood, Accoya.
Where is Accoya wood grown?
Accoya wood begins life in sustainably managed forests in New Zealand as a tree species called Radiata Pine. These forests are all FSC approved. The Radiata Pine is fast-growing and is shipped from here to the Netherlands for the modification process. We then ship across the world to our approved distribution partners.
Does the process affect the colour of the wood?
Acetylation causes no meaningful change to the colour of wood. There is a slight bleaching of red colours and a slight darkening of the outer surface of other wood. This is, however, insignificant compared to other processes such as thermal modification which deepens the colour of wood to dark brown.
Is Accoya Hardwood or Softwood?
Accoya is a modified wood. Accoya begins life as a softwood known as radiata pine but it is modified through the Acetylation process. This makes it much stronger, yet it remains real wood and is non-toxic. It is class 1 durability, extremely stable and structurally certified.
What paint to use on Accoya?
Multiple finishing options are available for Accoya, from natural-looking oils to high performance paint systems, all in an infinite variety of colours. There is not one specific brand of paint to use. Although, within each brand there may be some products that are better suited for use on Accoya than others in certain situations. It is also important to follow the correct procedures for preparation and application of the paints and stains.
What makes Accoya so special?
We constantly refine and improve our processes to improve quality and efficiency, and research the effects with different wood species.
