Aspen (genus Populus) is a white and soft wood, but fairly strong, and has low flammability. It has a density of 28 lbs/ft3 (450 kg/m3). It has a number of uses, notably for making matches and paper where its low flammability makes it safer to use than most other woods. Heat-treated aspen is a popular material for the interiors of a sauna.
