Sauna Wood, Thermally-Modified, Tongue & Groove, STP Profile, Medium Gap, Wall Material
Prosaunas Thermo-Spruce tongue and groove 1x4 STP profile creates an attractive surface, and is recommended for sauna walls and ceilings. Thermo-Spruce wood has a smooth refined finish and a traditional rustic charm with its characteristic rich amber color and highly figured knotty look.
Thermally modified wood is highly desirable for use in saunas. Thermal modification is a completely organic process that uses heat, steam, and pressure to physically enhance the properties of the wood. Sauna wood that is thermally modified is more dimensionally stable, more water-resistant, has an ideal moisture content, and is far superior to untreated wood for resisting decay, pests, and harmful fungi.
STP is an elegant profile that produces a refined and attractive wall surface for your sauna with its narrow grooves between broad cladding boards with rounded edges. It can be combined with other wood profiles for a contrasting appearance and to create your own unique, personalized look.
