Produced in Finland and the United States from locally sourced wood, Lunawood ThermoWood® products are manufactured without the addition of chemical preservatives and are designed for use in environments subject to temperature and moisture variations.

Its dimensional stability, durability, and resin-free structure support consistent performance under repeated heat and humidity exposure.
