Sauna Wood, Thermally-Modified, Tongue & Groove, STP Profile, Medium-Gap, Wall Material
Thermally modified wood is crafted through an eco-friendly process using heat, steam, and pressure. This natural modification enhances the wood's stability, moisture resistance, and durability, making it more resistant to warping, decay, pests, and fungi. With optimized moisture content, Thermo-Aspen outperforms untreated wood in sauna applications, offering unparalleled quality and longevity.
The STP profile combines narrow grooves with broad cladding boards featuring rounded edges, resulting in a refined and cohesive appearance. This profile is perfect for creating seamless sauna walls and ceilings. For a personalized design, it can also be paired with other profiles to achieve a unique and striking look.
At Premium Saunas, we prioritize quality by sourcing only the finest Thermo-Aspen from Northern Europe and Canada. Our team’s 55+ years of experience in sauna craftsmanship ensures that every piece meets rigorous quality standards, providing you with wood that enhances both the functionality and aesthetics of your sauna.
