According to ProSaunas, aspen has very good dimensional stability, does not split when nailed, and its low heat conductivity keeps it comfortable to the touch in a hot sauna. Aspen is the widest range here, so it suits a room built entirely in one wood, and the black-finished Midnight Black boards give a black wall or bench in the same species. The natural boards are unoiled; for the same wood in golden brown, see Thermo-Aspen.
