Thermal modification uses heat to change the wood itself, without adding chemical preservatives. The resulting material offers improved dimensional stability, durability, and resistance to moisture and decay.

We start with the application, then discuss the hardwood product, dimensions and volume your production requires. For a manufacturer, the useful question is not simply whether the wood has been treated—it is whether the specified material fits the way the finished product will be made and used.

For production Flooring, decking, siding and furniture applications.

For procurement Product and volume established before a supply quote.
