Thermal Treatment
Craft and benefits
Thermal treatment heats wood in a chamber to 180–240 °C with no chemicals. The fiber structure changes: the floor becomes more stable with humidity changes, resists warping and shrinking, and gains a deep dark tone (brown, caramel, graphite). Suited for use over underfloor heating, in variable climates, and where predictable long-term behavior matters.
How it works
Thermal treatment heats wood to 180–240 °C in a special chamber (often with inert gas or reduced oxygen), with no chemical additives. The fiber structure changes: moisture resistance and dimensional stability improve sharply—the material barely warps or shrinks with humidity. The wood also darkens to deep brown, caramel, or graphite. It is an eco-friendly alternative to chemical staining. Thermally modified wood suits floors over underfloor heating, in variable climates, and where long life and predictable behavior matter.
