Sustainability

Arbor Wood believes building materials should sustain our lives, our communities, and our planet. That is why they are committed to an ongoing sustainability strategy focused on creating positive impact on our industry as well as our planet. Arbor Wood puts this commitment into action by sourcing wood from responsibly managed American forests, using advanced thermal modification technology, finding productive uses for all byproducts (including waste), partnering with leading sustainability organizations, and supporting local and national reforestation efforts.

Unmatched Durability & Natural Beauty

Arbor Wood is a thermally modified, eco-friendly alternative to composite, synthetic, and chemically treated decking and siding. Because it absorbs less water, it is far less likely to expand, contract, rot, or decay. This process allows native wood species that are not usually suitable for exterior use to meet or exceed performance standards, with a beautiful appearance and long service life.

Arbor Wood thermally modified wood products:

Locally and sustainably harvested from American forests
White Ash, Poplar, and Southern Yellow Pine are carefully sourced from responsibly managed American forests, helping to protect the landscapes we all depend on while delivering an exceptionally low carbon footprint.
Enhanced durability
The Thermowood process changes the wood at the cellular level, increasing its resistance to rot, decay, and insects—much like tropical hardwoods. It is non-toxic and will not leach.
Improved dimensional stability
The process makes the wood highly resistant to water and moisture from severe weather, storms and humid air, greatly reducing the risk of warping or cupping and improving its resistance to expansion and contraction.
Non-toxic and chemical-free
No preservatives are used in the thermal modification process, the treatment relies solely on heat and steam and a proven production process.
Richer color and appealing aesthetics

The process gently darkens the wood, creating a warm, rich tone with a more consistent, uniform appearance.
Low maintenance
Arbor Wood thermally modified siding can be allowed to weather to a natural silver-gray or maintained with exterior oil to preserve its original color. In either case, applying an oil finish during the first season is recommended for best performance.
