Our thermally modified spruce products offer a softwood solution with exceptional rot resistance (Class 1 durability rating of 25 + years) and longevity combined with rustic knots and a naturally light colour.
Thermally modified spruce gives a facade a natural rustic look that will last for decades. Spruce wood acquires excellent weather resistance and biological durability as a result of thermal modification as well as a naturally beautiful light golden tone.
Thermal modification gives spruce the highest durability class (class 1) which means it will last for decades in all climate conditions. The treatment process also adds a beautiful golden brown tone to the wood.
The moisture absorption capability of spruce is reduced as a result of thermal modification, dramatically reducing its ability to rot.
