Thermowood is a thermally modified timber. The process typically involves heating lesser durable softwoods at high temperatures in order to remove moisture and resin and permanently enhance them. The timber may also be injected with chemicals. The result is a very durable and stable product.
As a result of the ThermoWood process the typical characteristics of softwoods are improved to levels often found in tropical hardwoods; i.e. high durability and excellent stability. These properties are consistent throughout the entire cross section.
RESISTANCE TO FUNGAL ATTACK
Thermowood also has significantly improved levels of durability against fungi attack. With a durability rating of class 3, Thermowood should be capable of satisfying performance requirements for 30 years of service when used for cladding.
RESISTANT TO INSECT ATTACK
Our Thermowood has proven resistant to attack from the three most common woodboring insects found in Europe – House Longhorn beetles, the common furniture beetle and the powderpost beetle.
ThermoWood has an attractive golden brown appearance which if left without any surface coating will start to grey and weather in quite a short period of time.
As a result of the ThermoWood process there is a reduction in the splitting strength properties of Thermowood compared to the original timber.
As no substances are added during the Thermowood process, no chemical leaching will occur. Also, as the resin is removed during the process the problem of resin leakage through knots or pitch pockets is also removed.
