The proven superior performance, delivered by the wood improvement method, has long been used as the “gold standard” against which other methods are measured.
It is also believed that enzymes’ digestion of wood initiates at the free hydroxyl sites – which is one of the principal reasons why wood is prone to decay.
The transformation from the free hydroxyl group to an acetyl group, greatly reduces the water absorption ability of the wood, and render the wood more dimensionally stable and extremely durable.
Accoya® wood, the end product, has no toxins in itself, moreover it releases none toxins to the environment.
Accoya® wood is modified right through the cross section . Whereas, by contrast, virtually all other treatments merely insert chemicals (such as oils, ammonia or metal compounds) into the wood, to improve durability to a degree, but without dimensional stability.
