Airwalls are no longer produced today. Some time in the middle part of the twentieth century, airwalls transitioned into operable partitions or folding panel partitions. Manufacturers phased out airwall bladders for insulation and other acoustical materials. Operable partition production with better materials meant that moveable walls were lighter and could have better acoutical effects.
Today, some people who work in hotels and schools still refer to operable partitions as airwalls. While the interiors of these two types of walls may differ, they are still essentially the same thing. They provide a versatile way to divide rooms in order to increase the usability of a space.
