The SSP Specseal Putty Pad is used to seal through penetrations, construction gaps, and blank openings. These putty pads for electrical boxes are sound and fire tested to maintain maximum sound and fire ratings. Each pad is a 7-1/4” square and 3/16” thick, about double the thickness of most putty pads. The thicker pad increases sound isolation performance as well as the fire rating. These pads are manufactured by Specified Technologies under the model number SpecSeal SSP4S.
The most common application for the SSP Putty Pad is putting the electrical putty on the back of outlets. The loss in mass created by an electrical outlet opening needs to be restored. The SSP Putty Pad is the best product for this because of the high performance in sound isolation and safety in fire rating. Acoustic putty pads for electrical boxes are only required if your wall has more than two single gang outlets within 100 square feet of surface area.
