Thermowood Product

ThermoWood®

Backegards has successfully for several years produced high-quality products from ThermoWood in various types of wood. The production method of ThermoWood® is a result of extensive development work and it is based on the controlled modification of timber with heat, steam and water. The modification phases are high-temperature drying, thermal modification and cooling, and moisture conditioning. The process results in permanent physical and chemical changes in the wood. The new properties remain unchanged, even when the timber is processed with methods such as sawing or planing. This also applies to the colour of the product (through-stained). There are two classes of ThermoWood®: Thermo-S (185-190°C) and Thermo-D (212°C).

Thermowood® has the following features:

  • Reduced swelling and shrinkage due to moisture
  • Enhanced dimensional stability
  • Better biological durability
  • Darker colour
  • No resin
  • Lower thermal conductivity
