Prosaunas Aspen Midnight Black 1x4 T&G STS4, Nickel-Gap, Wall Material

Prosaunas Aspen Midnight Black tongue and groove 1x4 STS4 profile creates a striking contrast, and is recommended for sauna walls and ceilings. This black-wax finished cladding is perfect for creating a dynamic, contemporary look. When paired as an accent wall with different bench and surface woods, its smooth black appearance will complement the lighter materials.

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.

The narrow, angular grooves of STS4 wall panels produce the modern nickel-gap look. STS4 can create a sophisticated contrast effect when combined with other wood profiles. Prosaunas distinctive nickel-gap panels are precision-milled to our precise specifications, creating a contemporary Scandinavian aesthetic.

Wood Sizing - Nominal vs. Actual Lumber Sizes: In North America, wood sizes are given in "nominal" measurements, which is the lumber’s size when it is cut from moist logs. After shrinkage from drying and surfacing, the actual size of lumber will be less than its nominal size. Please see the diagram for actual dimensions.
