Improved Durability

Accoya^®’s wood’s durability is Class 1, matching and even exceeding the performance of nature’s most durable woods. Durability is assessed by measuring weight loss over time in exposed conditions. Acetylation has been shown to improve durability against brown rot, white rot and soft rot significantly, with the percentage reduction in original mass being negligible compared to unmodified wood.

One of Accoya^®’s main advantages is that its key properties can be analysed by standardised scientific measurements after modification, enabling its durability to be guaranteed.
