Wooden Gates - How is Accoya wood made?
The technology behind Accoya® is based on wood acetylation, a process that has been studied by scientists for more than 90 years. The process alters the cell structure of wood, improving its technical properties and making it much stronger and more durable. Unmodified wood contains ‘free hydroxyl groups’ that absorb and release water as weather conditions change. This makes standard wood susceptible to expansion and contraction, particularly when used outdoors for applications such as cladding, window and door frames.
