What is Accoya?

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. The raw timber undergoes a patented modification process using non-toxic vinegar.

This acetylation process alters the wood’s cell structure. This modification reduces the wood’s ability to absorb water in the cell walls by about 80%, greatly improving dimensional stability.

The change in cell walls means that insects and fungi do not recognise Accoya wood as a food source and therefore do not attack.

Accoya wood is Class 1 durable and surpasses even the most durable old growth tropical hardwoods such as teak, making it the perfect choice for inground applications such as fence posts.
