Dark Thermo-Alder Wall Paneling 1×5 STS4 – Intense Thermal Modification Sauna Wood by Thermory

Thermal modification darkens wood, and intense thermal modification darkens wood even more.  It also takes the benefits of thermal modification to the next level. Wide plank 1×5 thermo-alder is an exceptional sauna wall material that can be installed vertically or horizontally.  The natural brown tone provides a classic, upscale sauna look.  Thermally modified alder is one of the best-performing sauna woods, with a warm tone, unbeatable performance, and timeless appeal.  The minimal expansion and contraction of Dark Thermo-Alder allows for tight, seamless transitions without molding.
