Acoustical Pads are designed for those who seek perfection in their soundproofing project. Electrical outlet boxes are a commonly overlooked area, and if not properly secured, soundwaves can easily penetrate the boxes and drastically compromise the soundproof properties of the wall. These pads are molded around the boxes to ensure your wall retains its proper STC performance.

Putty pads are UL fire rate and can be used in fire rated walls. The intumescent fire stop properties which will prevent the spread of fire, up to 2 hours. See Technical Data Sheet for more details.

Pads dimensions are 7" x 7" x 1/8" and are peel and stick. Simply peel the paper off the pads and attach around the outlet, cutting where necessary to allow for wire penetrations.
