Product Overview
Durable and low maintenance Thermowood
ThermoWood® is produced by heat-treating Finnish-grown pine and spruce to temperatures in excess of 200 degrees centigrade. During the heat treatment, chemical and structural changes occur within the timber which alters and improve some of its basic characteristics. The resulting product is an altogether more durable and stable timber, an ideal cladding material for use in exposed areas such as external walls.
Visual quality
The colour of ThermoWood-D (pine) is affected by the treatment temperature and time. The higher the temperature, the darker the appearance.
30-year service life
Uncoated ThermoWood-D (pine) exterior cladding can provide a 30-year desired service life. This calculation is based on a number of conditions including the quality of the workmanship at the time of installation, and the exposure of cladding to the weather including location, elevation, and design. If coated, over the life of the product, ThermoWood-D will have a 60-year desired service life, providing the coating is maintained in line with the coating manufacturer's recommendations over the service life of the product.
Environment
The timber used to produce ThermoWood® is grown in our own Finnish forests which are fully certified under the Finnish Forestry Certification System and Pan-European Forestry Certification. As such you can be sure ThermoWood® is sourced from well-managed and sustainable forests. The heat treatment process requires no chemical additives. The improved performance is achieved simply by the controlled application of heat and steam.
