QuietPutty® is Class-A fire-resistant acoustical putty designed to preserve the performance of STC rated assemblies. Use QuietPutty on electrical outlet boxes, rocker switches, HVAC ducts, water hookups, cable systems or any other penetration that require an acoustic seal. QuietPutty is clean, easy to use and requires no tools to apply. QuietPutty will not shrink and remains soft over time, ensuring a long-term seal that maximizes STC performance.
