Decking and Siding
Chemical-free durability
Finnforest ThermoWood® is the perfect material for structures that have to withstand continuous changes in temperature and humidity.
Finnforest ThermoWood® is a decking and siding solution that resists insect and water damage like pressure-treated lumber, but no chemicals are used in the production process. Now your customers can have a safe and durable solution for exterior and interior siding and decking.
This all-natural, solid wood product offers greater dimensional stability, along with improved decay and insect resistance. The wood is lighter in weight, resin-free and has an attractive, consistent color.
Made with PEFC-certified Nordic Pine and Spruce from sustainable, managed forests in Finland, it is a naturally carbon-neutral product. The production process uses about the same energy as kiln drying. A patented three-stage treatment process controls heat, time and moisture to close wood fibers and remove natural sugars. No chemicals are used, so it is very eco-friendly.
When left untreated and exposed to UV light, Finnforest ThermoWood weathers from its dark brown color to a soft grey. A clear sealer can be used to keep the original dark brown color. It accepts surface treatments well–both because of its stability and because there is no resin leakage.
Finnforest ThermoWood is available in several profiles for siding and decking. Download product data sheet for all measurements.
