Acoustical Putty Pads

Acoustical Putty Pads are UL-classified for both non-metallic and metallic outlet boxes to prevent the spread of smoke, fire, and toxic gases. Putty pads are sized to cover standard-size outlet boxes and are designed to work with sound-rated wall assemblies. UL classified Maintains acoustical ratings per ASTM C 919 and ASTM E 497 Testing to UL 263 (ASTM E119) and UL 1479 (ASTM E814) Outstanding adhesion to outlet boxes and other substrates Non-Hardening, permanently resilient Water-resistant Complies with Section 712.3.2 of 2006 IBC UL listed for metallic and non-metallic outlet boxes Technical Data Unsealed outlet boxes weaken the soundproofing rating (STC) in acoustic assemblies. A wall designed for noise control will not perform to expectations when outlets are unsealed, particularly when outlets are back-to-back in the same stud cavity. Acoustical Putty Pads can be hand-formed around the back of the outlet and lightboxes to prevent this common sound leakage problem in stud wall
