What is Thermarich Lumber?
Thermal modification of wood is a natural process of “cooking” the wood in oxygen-free ovens to temperatures over 400 degrees. Thermally modified wood is an excellent alternative to chemically treated lumber. The thermal modification method changes the wood’s cellular and molecular makeup, removing all the wood’s organic compounds.

Common Questions & Answers
Pressure Treated Wood uses fungicidal chemical preservatives to protect the wood.
Thermally Modified Wood has a similar kiln drying process. The moisture content is reduced to nearly zero, and the molecular structure of the wood is changed with the introduction of high heat. The results of thermal modification are similar to pressure treated, where it protects against outdoor elements. However, it only uses heat over 400 degrees to produce natural rot-resistant wood without chemicals.
