Arbor Wood

Thermally Modified Wood

Arbor Wood Co. produces thermally modified wood for a variety of outdoor and indoor applications including siding, decking, and architectural millwork. Their process starts by using domestically and responsibly sourced wood which is thermally modified using only heat and steam. The result is a high-quality, performance-driven material, which sustains the natural beauty and design element of wood all without the use of harsh chemicals.

Thermal modification is a unique craft which alters wood at the cellular level to create a material that is functionally and visually successful in a range of residential and commercial applications. High heat and steam replace chemicals to fundamentally modify Arbor Wood’s hemicellulose, making it one of the most natural, chemical-free ways to extend the service life of a wood product. The wood is less absorbent, resulting in increased material stability with less warping/cupping and minimal expansion/contraction. Additionally, certain organic compounds are eliminated during modification thus removing the food source for rot and insects. The conversion of sugars to a nonfood source also turns the timber a darker, richer through-color, providing an appealing and refined aesthetic.

The thermal modification process affects wood’s relationship with water by breaking down the hydroxyl groups in the wood and eliminating the bound water, making Arbor Wood less prone to mold, rot, and fungal decay. The wood is also less likely to absorb new moisture and has a reduced equilibrium moisture content, reducing the chance of swelling and shrinking by up to 60%. The lower moisture content reduces the overall weight of the wood and helps support the general workability of Arbor Wood.

Siding

Arbor Wood Co. thermally modified wood siding uses domestically sourced and sustainably harvested timber. Thermal modification allows for wood not naturally suitable for exterior applications to be successful because of its compositional change on a cellular level. A performance-driven and attractive material, Arbor Wood is a sustainable option for your next project. Learn more here.

* Indicates WUI Approved Option

Decking

Arbor Wood is an eco-conscious alternative to composite, chemical-treated or exotic hardwood decking. Because thermally modified wood is less prone to water absorption, expansion/contraction, rot and decay, woods not typically suitable for outdoor applications are able to perform with a long service life.

* Indicates WUI Approved Option.

Dimensional Lumber

Arborwood produces a range of dimensional lumber profiles in all of their thermally modified wood species and finishes. Perfect for architectural millwork, trim or most places where the stability and beauty of Arbor Wood can enhance your project. Learn more here.


Color Change

Thermal modification changes the naturally occurring sugars in the wood resulting in beautiful, rich tones which extend through the full thickness of the material. Since Arbor Wood is still a natural product, the grain and unique characteristics of the wood remain. In an exterior environment, Arbor Wood will move to gray when unfinished and the application of a UV inhibitor helps maintain the original color.
