100% natural heat process with steam and water

ThermoWood® is the result of an innovative process in heat treatment is the main factor. The ThermoWood® production process uses heat, steam, and water. The timber undergoes prolonged heating at temperatures up to around 208°C. This treatment causes certain chemical changes to the timber, creating a hard-wearing and stable product that is resistant to insects and wood rot.
