Discover the enhanced durability and stability of our thermally modified wood selections.
What is Thermally Modified Wood?
Thermal modification utilizes intense heat and steam to transform the wood's chemical properties. By altering the cell structure and reducing moisture movement, the process enhances the wood's stability and durability by making the wood better able to withstand moisture changes without expanding or contracting, as well as resistant to mold, rot, and insects.
The thermal modification process opens the door to new applications of traditional wood species. Domestic wood species, for example, are often not durable enough to withstand outdoor conditions. This process transforms these woods so that they are able to endure weather and heat well enough for outdoor applications like siding or decking. Plus, by choosing domestic species, we’re able to curb our environmental impact by minimizing shipping, while offering our customers a better, stable price that remains unimpacted by tariffs or supply chains.
The thermal modification process is a days-long operation and consists of the following stages:
Details of this process, including the timing, depend mainly on the wood species and the dimensions and moisture content of the raw material.
