The company Ets Röthlisberger SA install in 2006 in Glovelier a heat treatment plant. To amend specific properties of wood, our THERMO-treatment (also known as thermal or heat treatment) expose Hard- or Softwood to high temperatures (150 bis 200°C) for a definite duration in a special process. Our VAPO-treatment also occurs in a satured steam, but with lower temperatures, to insure the perpetuation of structural properties of timber. These are very ecological processes: they don't use any treatment product and allow new valorisations for our local wood species.
Main advantages of heat treated timber (also called thermowood, or heat treated wood):
-
Thermowood has stabile dimensions: the humidity of timber is consequently reduced, and also the possible water absorbtion. Schrinkage and swelling are decreased up to 60%
-
Thermowood is durable: the heat treatment achieve a degradation of the hemicellulose. So becomes the timber much less attractive for wood destructing micro-organisms, and therefore much more durable. Heat treated timber can be used for outside uses, but without ground contact.
-
Thermowood is noble: The heat treatment confere our home-grown wood species noble and precious character. New exotic wood tones are given to all the timber thickness.
Applications of heat treated wood (Thermowood):
-
Wellness- and wet areas, swimming pools and saunas
-
Outdoor flooring
-
Windows, shuters and outer doors,
-
Claddings and clapboards
-
Garden furniture, Carports

Playground equipments
