What is Thermowood?

Thermowood® is a a heat treated timber, suitable for internal and external applications. Thermowood® is strengthened by a unique curing process. This is a natural process which uses only heat and steam - no chemical additives are used. This unique process makes Thermowood®dimensionally stable, resistant to decay and resin free.

Furthermore, It can be used inside or outdoors, in any climate. Dark brown in colour throughout, Thermowood® has all the character and warmth you would come to expect from real timber. If left untreated the colour will turn a silver-grey. Or, treatment can be easily applied for colour protection. Made from carefully selected Northern Scandinavian Redwood (Pinus Sylvestris).
