Classrooms - When adjacent to a music room, mechanical room, or cafeteria, the wall STC rating should be a minimum STC 60 per ANSI S12.60-2002. The same applies to floor/ceiling STC ratings.
Band rooms, music practice, music rehearsal spaces and auditoriums require high STC walls and, depending on location, may need floor/ceiling isolation.
Floors - Model RIM roll-out isolation material for isolating a concrete slab or a heavy built-up composite floor. Note: In some cases where low-frequency vibration intrusion is a concern, the Model LSM spring liftslab system is utilized.
Walls - The Model IsoMax single stud wall design can meet requirements by boosting the STC to 57-65 depending on the thickness of the drywall. The IsoMax system is also an excellent way to finish a masonry wall with furring-mounted gypsum wallboard on the isolation clips. The combination of grout-filled masonry and sound-isolated gypsum board on one side produces a high-performance wall across a broad frequency range.
Ceilings - Model ICC spring and neoprene ceiling isolation hangers for suspended gypsum board ceilings attached to the deck above. For lower profile, compact assembly, see Model KSCH hangers. For the most economical hanger, see Model IsoGrid.
Note: Controlling sound reflections and reverberation levels is critical in auditoriums, rehearsal spaces, gymnasiums, and classrooms. Kinetics Room Acoustic Materials can contribute points to LEED classification in schools based on meeting the requirements of ANSI S12.60-2002.
