Thermally modified wood: The sustainable choice for beauty, quality, purity and durability, without the cost of exotic hardwoods.

What is Thermally Modified Wood?

• Thermal modification is the process by which wood is heated (>356°F) with steam in a controlled environment in the absence of oxygen. Low oxygen content prevents the wood from burning at this high temperature.
• Thermal Modification both transforms and enhances the structural properties of wood without the use of harsh or toxic chemicals. Thermal modification induces structural changes to the cell wall components, making the wood highly resistant to rot while greatly reducing expansion and contraction.
• Since Thermally Modified wood does not absorb or hold moisture as it would prior to treatment, species that typically do not perform well in outdoor or wet environments can now be used for decking and siding.
• Thermal modification brings out a natural refined darker richer color in the wood. If not properly finished with Penofin for Thermally Modified Wood, this unique dark rich color will fade to a silver-grey when exposed to rain and sun.
