Lunawood Spruce is a natural wood siding material made from thermally modified Nordic spruce in Finland. Through a chemical-free thermal modification process, ThermoWood® achieves a lower moisture content and reduced moisture absorption, resulting in exceptional dimensional stability. The Wood Source Caribou finish is inspired by the ghost town of Caribou in Boulder County, Colorado.

Suitable for exterior siding and soffit applications, Lunawood Spruce performs exceptionally well in high-altitude mountain climates. Its enhanced stability makes it resilient to temperature swings, providing reliable long-term performance with little maintenance required.

Featuring a natural wood appearance with subtle knots and rich color tones, Lunawood Spruce offers a refined yet organic look. The thermal modification process also gives the wood a distinctive, pleasant wood aroma.
