Clean Corners. Defined Edges.
PROSAUNAS Thermo-Aspen 2×2 Outside Corner Trim VA is a premium sauna finishing moulding designed to neatly cover and protect external wall corners. With its angled VA profile, it creates sharp, clean transitions while enhancing the overall appearance of the sauna interior.
Thermally modified Aspen offers improved durability and dimensional stability, making it well-suited for sauna environments. The heat treatment process reduces moisture movement and deepens the wood’s natural tone, ensuring consistent performance under high heat and humidity.
Each trim piece is precision-machined for accurate alignment and easy installation. The outside corner design provides both protection for exposed edges and a refined, professional finish that complements surrounding panels.
PROSAUNAS selects high-quality Aspen to ensure uniform color, smooth texture, and long-lasting reliability. This makes it an excellent choice for both residential and commercial sauna finishing applications.
