Exterior Materials

Thermally Modified Spruce

Thermal Modification of wood is a natural process using heat and steam in a vacuum to alter wood at a cellular level. When done right, it makes the wood significantly more durable, stable, and longer lasting. Thermo-Spruce is darker than raw spruce wood, closer in color and performance to Western Red Cedar.
