Exterior Siding & Interior Paneling

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.

Endless Versatility

The uniquely durable properties of Accoya®, created using an all-natural process, allow the wood to be utilized for a variety of purposes. Our sales representatives can customize your order to fit your precise needs and use-case scenarios.

Acetylated wood, at-scale.

Acetylation has been studied and practiced in the wood industry for more than 70 years. The process, by which wood is effectively “pickled” in an all-natural vinegar-like substance, was once considered impossible to produce in large quantities. With Accoya®, however, these barriers have been eliminated, and this durable real-wood non-toxic product can be produced and purchased at-scale.

And with Hewn’s expertise in coloring and finishing, Accoya® can be elevated to the next level, creating a timeless look and feel perfect for your next commercial or residential project.

Optional Custom Rainscreen

Hewn has partnered with Nova USA Wood to pair their industry-leading Rainscreen Siding ecosystem with our Hewn product offerings. Nova’s QuickClip Rainscreen Siding System is engineered by nature to withstand the test of time and the elements. Professional builders favor their products for their high quality, high performance and consistency.
