Accoya is the world’s leading high-performance wood. Non-toxic processes with natural acetic acid are used to treat sustainable and fast-growing pinus radiata, modifying its structure from the surface to its core. The method produces permanent, stable and enchantingly solid wood that adheres to even the strictest environmental standards (DIN EN 350-2 durability class 1).

Excellent performance

After extensive testing, Accoya timber has received the building inspectorate approval from the German Institute for Construction Technology (DIBt) in Berlin.

Low build-up of heat

Accoya is the perfect floorboard for barefoot enthusiasts because it does not splinter and accumulates far less heat than the tested alternatives, as shown clearly in the thermograms. During testing, the ambient temperature around all floorboards was 32 °C, and the dimensions of all three board types were comparable.

One-year weathering test

To show you the durability and resistance of Accoya, we have done a weathering test over a year, which you can find here.
