Premium Aspen 1X4 T&G STP Wall Cladding

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.

Note that lumber sizes are nominal, with actual sizes being slightly smaller after drying and surfacing.
