Finnforest Thermowood
The process that converts premium Scandinavian softwood to Finnforest Thermowood® is straightforward: each piece is steam heated in a kiln. The heat goes to the core of the wood, driving out moisture and resin. The result is a timber with reduced moisture content and enhanced physical properties.Finnforest Thermowood® is 50% more stable than untreated softwood. It suffers less shrinkage, swelling, and distortion in response to atmospheric changes. It is easy to work with and lightweight. The improved stability of Finnforest Thermowood® reduces the potential for shrinkage, warp or twist ensuring your deck or cladding looks great for years to come.Thermal conductivity of ThermoWood® is reduced by 20-25% compared with normal softwoods. According to VTT tests the thermal conductivity λ10 of ThermoWood® (D, pine) is 0.099 W/(m K).The corresponding value for untreated sawn timber is 0.12 W/(m K).
Finnforest ThermoWood® is PEFC – certificated which ensures the raw material is sourced from sustainable managed forests.
