Solid Structure. Lasting Strength.
PROSAUNAS Thermo-Aspen 3×3 S4SEE SHP is a premium sauna support timber designed for bench framing and structural components. With its square profile and smooth eased edges, it provides dependable strength while maintaining a clean and refined appearance within the sauna interior.
Thermally modified Aspen enhances durability and dimensional stability, making it ideal for demanding sauna conditions. The heat treatment process reduces moisture movement and deepens the wood’s natural tone, ensuring reliable performance under high temperatures and humidity.

Why Choose Thermo-Aspen Support Timber for Your Sauna Interior?
Three reasons sauna builders depend on this material for strong framing and reliable support.
Built for Sauna Heat
Thermally modified Aspen performs in high temperatures. Its improved stability reduces expansion and contraction - helping structures remain solid and aligned.
Resists Moisture Movement
The heat-treatment process limits moisture absorption. This helps prevent warping or shifting, ensuring long-term durability in humid sauna conditions.
