ThermoWood® Cladding

What is ThermoWood?

Finnish grown European Redwood (Scandinavian Pine) is heat-treated to temperatures in excess of 200 degrees Centigrade creating ThermoWood ‘D’.  This thermal modification process improves the wood’s properties, thereby expanding the range of applications in which it can be used. 

Why choose ThermoWood?

It has been known for centuries that burning the surface of the wood in an open fire will make it more durable in exterior use. 

During the heat treating process, the wood colour darkens, it becomes more stable than normal wood in conditions of changing humidity, and its thermal insulation properties are improved.  The treatment process also makes the wood resistant to decay.

ThermoWood ‘D’ will, therefore, provide a 30-year service life, when installed in accordance with the manufacturer’s recommendations.

Does ThermoWood cladding need protecting?

Although the lifespan of ThermoWood ‘D’ unprotected can reach up to 30 years in optimum environments, by applying a surface coating, you can achieve 60+ years if applied at the outset and maintained periodically.

However, because ThermoWood has a lower water absorption rate than normal wood Silva uses a specially adapted formula of Sansin Enviro Stain – called SDF HT - which has been developed specifically for use on heat-treated wood.

Factory coating service

ThermoWood ‘D’ cladding from Silva can be supplied factory coated enabling it to be installed at any time of year regardless of the weather or temperature.

Is ThermoWood sustainably sourced?

The timber used to produce Silva ThermoWood is sourced from well managed and sustainable forests which are fully certified under the Pan European Forestry Certification (PEFC) scheme. 

Why choose Silva Timber?

Silva Timber stocks a wide range of ThermoWood ‘D’ cladding profiles. Wood has been carefully selected to ensure that it meets the highest standards of quality at the most competitive prices.
