Thermowood Cladding

(16 Items)

Create beautiful, longer-lasting structures with our thermood cladding, designed to upgrade the look and quality of your walls, whether that’s for a home, shed, or sauna. 

Thermood exterior cladding is designed to be placed on the outside of buildings, protecting the material underneath from degradation while improving the appearance of the property. Since it undergoes thermal modification, which changes the chemistry of the wood, it’s one of the highest classes of wood available. 

When used for your home, it can protect the integrity of exterior walls by improving resistance to fungi and rot, promising high-quality walls for a longer time. Thermowood is typically made from fast-growing, FSC®/PEFC™ softwoods, such as pine, and is modified using heat and steam only, with no added biocides.

Its natural versatility also means it’s the most stable wood for areas that experience every type of weather, from harsh winds to rain and blazing heat; it has great insulation, keeping homes cool in the summer and warm in the winter. 

As trusted thermowood cladding suppliers, we offer a range of products, from tongue-and-groove to rainscreen cladding, available in beautiful tones like deep red and warm brown. 

With lower equilibrium moisture content and reduced swelling and shrinkage, you won’t have to worry about cupping and gapping issues, as they provide tighter joints and straighter boards for better durability. 

Thermood cladding installation is super simple because it’s easier to cut, fix, and detail on site compared to hardwoods and some modified woods. It’s also quite cheap for large projects and is a sustainable choice for eco-conscious buyers!

Our thermowood cladding takes oils, saturators, and vapour-open stains well if you want to preserve colour and keep your cladding looking fresher for longer. You should expect natural greying when installed outdoors, unless you apply and maintain a UV-resistant finish.
