Clean Edges. Smooth Finishes.
PROSAUNAS Thermo-Aspen 2×2 S4SEE SHP is a high-quality sauna trim moulding designed to refine edges and cover transitions between wall or ceiling panels. With its square profile and eased edges, it delivers a clean, continuous look while enhancing the overall detail of the sauna interior.
Thermally modified Aspen provides improved durability and dimensional stability, making it well-suited for sauna environments. The heat treatment process reduces moisture movement and enriches the wood’s natural tone, ensuring dependable performance under heat and humidity.
Each piece is precision-milled for consistent sizing and straightforward installation. The S4SEE profile ensures all sides are smoothly planed with softened edges, offering both a polished appearance and safe handling during installation.
PROSAUNAS selects quality Aspen to achieve uniform color, fine grain, and long-lasting reliability. This makes it an excellent choice for finishing work in both residential and commercial sauna designs.
