Alder STS4 Sauna Wood - Wall Paneling T&G 1x4 is crafted from natural European alder, a hardy and resin-free wood prized for its smooth texture, low heat conductivity, and beautiful reddish-honey tones. This profile features a modern STS4 tongue-and-groove design that creates a precise 4mm shadow line, providing a clean, architectural linear aesthetic for high-end sauna and interior walls.
