Thermo-Aspen Sauna Wood - Wall Paneling 1x6 T&G STS4

Thermo-Aspen Sauna Wood - Wall Paneling 1x6 T&G STS4 is crafted from premium Finnish Aspen that has been thermally modified for enhanced durability and a rich, warm brown tone. The heat treatment process uses only heat and water vapor (no chemicals), making the wood harder, more dimensionally stable, and naturally resistant to moisture. This panel features a flat tongue-and-groove (STS4) profile for seamless installation.

Available Lengths: 2-9.8 ft.

This wood is sold as an individual board. The profile and surface appearance of lumber can vary slightly between production runs.
