Thermowood Facade Cladding

Thermowood facade cladding combines the warm and natural appearance of timber with improved dimensional stability and exterior performance achieved through thermal modification.

The controlled heat and steam treatment reduces the wood’s tendency to absorb moisture, improves form stability and supports more consistent performance in outdoor applications. For this reason, thermowood is preferred in villas, residential buildings, hotels, offices, commercial projects and social facilities where a natural, warm and prestigious facade appearance is required.

It can be used for vertical or horizontal cladding, timber slat facades, soffit applications, sun shading elements and decorative exterior surfaces. With the right substructure, ventilated facade detail, fixing system and surface protection method, long-lasting and visually refined applications can be achieved.

In thermowood facade systems, proper detailing is as important as the material itself. Exterior timber cladding should be designed by considering rain, sunlight, wind, humidity, expansion and installation tolerances.

Before application, facade orientation, climate conditions, carrier substructure, ventilation gap, screw or clip selection and surface protection method should be evaluated together. Thermowood preserves the natural character of timber while developing a distinctive surface appearance over time. If no protective oil or coating is applied, the material may naturally turn into grey tones.
