ThermoWood Cladding Shadow Gap – A Grade – 20mm


Thermowood cladding refers to a type of exterior wood cladding that has undergone a thermal modification process to enhance its durability, stability, and resistance to decay. It is typically made from softwood species, such as pine or spruce, that have been heated to high temperatures in the absence of oxygen.

During the thermal modification process, the wood is heated to temperatures of around 160-220 degrees Celsius. This heat treatment alters the chemical and physical properties of the wood, resulting in improved dimensional stability and reduced moisture absorption. The process also enhances the wood’s resistance to fungal decay, insects, and weathering.

Thermowood cladding offers several benefits for building exteriors. 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.

Thermowood cladding ShadowGap is a leading product in the modern construction market. It is one of the best natural building materials ideal for sustainable projects. Thermowood is heat (chemical free) treated timber. Because of how it is heated, wood becomes durable in any weather and does not deform, warp, rot or change colour. Secret fixing can be easily used on Thermowood. No treatment is required for this wood, however some may choose to apply some stain or oil if desired.

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.

Overall, thermowood cladding provides a durable and visually appealing solution for external wood cladding, offering improved stability, resistance to decay, and a distinctive appearance.
