Aspen ThermoWood® – also known as ThermoWood® poplar or Thermopoplar for short – is heat treated wood from the poplar or European aspen. It is an excellent alternative to tropical hardwoods, such as Afrormosia and African Padauk.

Thermopoplar undergoes thermal treatment in which the wood is heated under pressure and at high temperatures under inert atmosphere. The wood receives a steam treatment, as it were, in a steam oven without oxygen and at a temperature of around 200°C.
