Thermowood cladding pack 21mm (5 Boards )
Clad your sauna with the rich tone and lasting durability of Thermowood Pine D cladding. Produced through a specialist heat-treatment process, Thermowood offers enhanced stability, resistance to warping, and a naturally deep colour that adds warmth and style to your sauna.
ThermoPine D is a natural, chemical-free product. Instead of using treatments, the timber is carefully heated to 212°C, a process that transforms its structure and enhances its performance. This heat treatment eliminates the risk of chemical leaching while improving durability, stability, and resistance to decay. As a result, Thermowood cladding is an excellent choice for exterior use, with an expected service life of up to 30 years.
Each board is smooth, precision-cut, and designed with a tongue and groove profile for easy installation and a seamless finish on both walls and ceilings. The heat treatment ensures excellent performance in sauna environments, resisting high temperatures and humidity while maintaining its elegant look.
Sustainably sourced and carefully finished, Thermowood D is a premium choice for both outdoor and indoor, home and commercial saunas,.

ThermoWood D
Thickness, Grain, Texture and Profile. The external cladding is extra thick 21mm ThermoWood, which has a straight grain and fine texture. Our profile has been specifically designed to have a long tongue for secret nailing which gives a modern appearance with clean straight lines.
What is ThermoWood? ThermoWood or more specifically ThermoPine D has not been chemically treated in any way, instead the timber is slowly heated to 212°C so no chemical leaching will occur. The process modifies the characteristics of the timber and provides it with a host of benefits making it highly durable and an ideal choice for exterior cladding. Thermowood cladding should deliver a service life of 30 years.
Stability
ThermoWood has dramatically reduced swelling in humid conditions. In addition the comparison with species such as Western Red Cedar (WRC) and Larch which are typical cladding materials prove to be very positive.
Colour. ThermoWood has an attractive golden brown appearance. ThermoWood cladding if left without any surface coating will start to grey and weather in quite a short period of time, as can be expected with all natural wood products which are exposed to the weather effects.
