ThermoWood Charred / Burnt Timber Cladding

Our ThermoChar range follows a specialist and bespoke process. We are the only UK producers of Charring Thermally Modified Hardwood and Softwood.
This process takes previously Thermally Modified hardwoods and softwoods produced at our factory and then charring/burning the outer surface in a variety of ways. Therefore, this process makes the boards far more fire-resistant than standard charred/burnt timbers such as larch and cedar etc. All the resins, sugars and tannins that are normally present in timbers like larch and cedar have been removed. With this in mind, by applying the additional process of charring/burning the surface, the result is a much improved charred surface. Overall, eliminates the risks of the timber igniting when exposed to sparks or flames. Only Heavy charring becomes 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 ongoing maintenance is required.

Our ThermoChar® collection is sealed using our specially formulated: QFlex® - A flexible, UV, Sealer.

Only Heavy charring becomes UV resistant to fading.

Please note: The charring/burning process is not an exact science and therefore there will be slight surface burn variations throughout the board length which adds to the unique charring/burning characteristics of each board and species. In fact, ThermoWood is 30% more fire-resistant than regular wood. Also bear in mind that the softwood char on Pine and Ayous is more delicate than the hardwood Ash and should be handled with more care prior to and during installation to prevent any compromising of the surface finish. All delivered material has a protective layer between the boards, this should be utilised onsite until and during installation. Stacking and carrying several boards will rub the surface together and may compromise the finish. The timber itself will be unaffected in terms of durability.
