ThermoWood is produced by heat treating Finnish grown pine and spruce to temperatures exceeding 200 degrees centigrade. During the heat treatment, chemical and structural changes occur within the timber which alters and improves some of its basic characteristics. The resulting product is an altogether more durable and stable timber, and is ideal as a cladding material for use in exposed areas such as external walls.
