It is primarily used in theaters, sound studios, public concourses, and other areas where acoustical treatment is needed. It is intended to be mechanically fastened to walls, or suspended above liner metal and metal pan ceiling systems to serve as both a visual and acoustical treatment. In addition, it can be covered with fabric or draping.
