Thermowood uses a modification method using heat / high temperatures and steam to change the properties of the wood e.g the durability against wood destroying fungi, dimensional stability, and appearance. We supply Thermowood Redwood D Pine, Thermowood Ash, Thermowood Poplar, Thermowood Ayous Clear Cedar and Thermowood Radiata Pine
It is considered an environmentally friendly way of wood treatment as no chemicals are added during the process. The level and intensity of heat used during the thermal modification will result in differing properties.
Thermowood D is classified as durable having been treated to higher temperatures and can be used for both internal and external applications whilst Thermowood S is treated at lower temperatures is classified as stable and used for internal applications.
Using heat for thermal modification has been known to have existed since the Viking period but has become popular in the last 10-15 years with large-scale commercial production plants being set up across the globe, mainly in Scandinavia and Estonia.
The process is used to enhance the durability and stability of timber products for both internal and external applications for example decking boards, floorings, timber cladding, wood shingles saunas, hot tubs for both internal and external applications.
Recently we have seen the rise in hardwoods and clearer high-quality Thermowoods being readily available and an increase in factory finished pre-painted and fire retardant treated Thermowoods.
Some of the leading brands of thermal modification include Thermowood D, Thermowood S, Thermory, Lunawood, Abodo Vulcan. Several major producers such as Thermory and VTT /YTI in cooperation with the Finnish wood product industry have developed industrial scale heat-treatment processes for wood. The ThermoWood process developed by VTT is licensed to the members of the International Thermowood Association.
In addition to carrying lines from members of the association, we also stock some of the largest quality brands of thermo treated timber from independent companies. They have produced a diverse and innovative range of thermal treated timber products with some of the highest certification standards and test data verified by independent laboratories. We have a large customer base for modular and garden building manufacturers. We supply Thermowood in various forms of decking, cladding (TGV, PMV, Shiplap) and sawn timber.
