ThermoWood® is the result of an innovative process in which heat treatment plays a central role. Thermal modifications ensure that the durability of the wood increases and its quality improves.
The first thermally treated wood was produced in the 1930s by the German scientists Stamm and Hansen, and in the 1940s by the American scientist White. Bavendam, Runkel and Buro then continued the research in the 1950s. At the beginning of 1990s the term ThermoWood® was coined for the first time when the VTT (Technical Research Center in Finland) further expanded the research to heat treatment, and thus the ´ThermoWood® method´ was developed.
The ThermoWood® production process uses heat, steam and water. Wood is heated for a long period at temperatures up to 208°C. This heat treatment also produces specific chemical changes of the wood, giving rise to a long-lasting and stable product.
