As the first company to produce acetylated wood on a commercial scale, Accoya® is leading the charge in providing durable and dimensionally stable wood for a variety of applications. In the acetylation process, softwood is essentially turned into a hardwood through the introduction of a non-toxic vinegar-like solution, creating a new type of wood that is durable all the way through the board, not just on the surface. In practice, this allows for a wood product that is significantly protected against the elements, making it perfect for installation in exterior environments where a standard sealed wood product would fail after only a short amount of time.
At Hewn, we build upon the extraordinary properties of Accoya® wood by applying our proprietary color and finish techniques to create beautiful, unique, and long-lasting wood products, suitable for a variety of applications, and customizable for the specific needs of your project.
