Sauna Wood, Tongue & Groove, Fluted Slat, Wall Material PROSAUNAS Aspen Groove-S 1x3 Wall Cladding brings personality and is recommended for sauna walls and ceilings. Its dramatic, precision-milled fluted slats add an upscale appearance. Aspen is an excellent choice when creating an upscale, contemporary looking sauna. Aspen is a perfect sauna material for many reasons. It has very good dimensional stability, does not split when nailed, and its thermal properties are ideal in a sauna. Because of Aspen's low heat conductivity, it will remain comfortable to the touch even in the extreme heat of a sauna. PROSAUNAS carefully selects only the finest wood from Northern Europe and Canada, assuring that the quality and consistency of our wood selection is the best available. Our team has more than 55 years of experience crafting premium sauna rooms across North America, and we only offer wood that meets our stringent standards. Because of our total commitment to quality, we can ensure your wood order will arrive to your satisfaction.
