Thermo-Alder STS4 Sauna Wood - Wall Paneling T&G 1x5 is crafted from natural European alder, a hardy and resin-free wood prized for its smooth texture, low heat conductivity, and warm reddish-honey tones. This wider 1x5 profile utilizes the STS4 tongue-and-groove design to create a bold 4mm shadow line, offering a sophisticated, modern linear look with fewer visible joints than narrower boards.

This wood is sold in a bundle of six boards.
