Its improved stability reduces the risk of warping, cracking, or shrinking, ensuring a long-lasting and visually appealing finish. The thermal modification process also leads to a darker coloration, giving the wood a rich and natural appearance. Additionally, the increased resistance to decay and insects makes Thermowood cladding suitable for various climates and environments.

Installation of Thermowood cladding is similar to other wood cladding systems, typically involving fixing the boards to a substructure using screws or nails. It can be used for both residential and commercial applications, adding an attractive and sustainable aesthetic to the building’s exterior.
