For centuries the Japanese perfected the art of charring/burning wood in order to make the wood resistant to fire, rot, insects and the UV effects from the sun. The process of charring/burning the outer surface brings out the richness of the different wood species grain structure. Also varying the intensity of the burning process produces different finishes.
The benefit of Thermally Modified wood (ThermoWood) is that all the resins, sugars and tannin’s that are normally present in timbers like larch and cedar have been removed so by applying the additional process of charring/burning the surface, the result is a much-improved charred surface, eliminating the risks of the timber igniting when exposed to sparks or flames. Heavy charring is also UV resistant to fading. If the surface is chipped or damaged it does not expose the natural parts of the timber that may lead to surface peel or potential decay and minimal on-going maintenance is required. These days the primary use is for aesthetics and improved performance in exterior applications.
NATURAL WOOD PANELS – WOOD PANELS BY DESIGN
After almost 18 months of experimenting and testing this process, the manufacturer has taken this labour-intensive process a step further by introducing the ThermoWood Charred Cladding Collection which takes previously Thermally Modified hardwood and softwood and then charring/burning the outer surface in a variety of ways. This process makes the boards far more fire resistant than standard charred/burnt timbers such as larch and cedar etc. Please note: that the charring/burning process is not an exact science and there will be slight surface burn variations throughout the board length which adds to the unique charring/burning characteristics of each board and species. ThermoWood is 30% more fire resistant than regular wood.
Species currently available: Thermowood Pine Softwood, Thermowood Ash Hardwood, Thermowood Tulip Hardwood are available in the charred collection. Other species will come online soon once fully tested. Safe.
ThermoWood is 30% more fire resistant than regular wood.
Combined with the charring/burnt process the boards become highly fire resistant.
