framing the perimeter track into shape, infilling the acoustical substrate and then stretching and tucking the fabric into the perimeter frame system. On-site wall panels can be constructed to accommodate door frames, baseboard, or any other intrusion. Large panels (generally, greater than 50 square feet (4.6 m)) can be created on walls and

Prefabricated panels are limited to the size of the substrate ranging from 2 by 4 feet (0.61 m Ă— 1.22 m) to 4 by 10 feet (1.2 m Ă— 3.0 m). Fabric retained in a wall-mounted perimeter track system, is referred to as "on-site acoustical wall panels". This is constructed by
