Finnforest ThermoWood
® is available in a variety of finished profiles:
Durability
The improved durability of Finnforest ThermoWood ® makes it an excellent material to use in the production of timber claddings and rain screens. The heat treatment process enables the use of Scandinavian Redwood in areas requiring a service life of up to 30 years without the need for a chemical preservative.
Stability
Finnforest ThermoWood ® is more stable than untreated softwood. The changes that occur within the timber during heat tratment make it less able to absorb or lose moisture. This restriction of moisture movement limits any potential for swelling, shrinkage or distortion of ThermoWood ® cladding boards.
Maintenance
Heat treatment removes resin from redwood timber. As a result there is no resin leakage or "bleed" through the surface coatings. The combined effect of this together with the improved stability can lead to a lower maintenance requirement.
