QuietRock 525

Easiest, lowest-cost way to meet code for multi-family party walls

QuietRock 525 sound damping drywall provides a simple, reliable, low-cost way to meet building code for multi-family party wall construction, as well as excellent performance for residential and commercial construction. A single sheet of QuietRock 525 on one side of single wood studs exceeds code for STC ratings – which lets you eliminate the added material and labor cost for double-stud construction and gain more sellable floor space.
