Alder Wall Paneling 1×5 STS4

Sauna Alder Wall Paneling 1×5 STS4 is a medium modified profile, giving it a balance of stability and the classic warmth of alder. While built for sauna wall applications, its clean tongue-and-groove profile and hidden staple installation also make it a strong fit for interior builds outside the sauna, such as accent walls or ceilings. The smooth texture and light, even grain provide a versatile, natural look. Medium modification preserves more of the wood’s natural character while still improving stability and moisture performance compared to unmodified stock.
