The SSP Putty Pad is used to seal through penetrations, construction gaps, and blank openings. These pads 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.
The most common application for the SSP Putty Pad is the back of electrical 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. Putty pads are only required if your wall has more than two single gang outlets within 100 square feet of surface area.
DOORS AND WINDOWS
The space between the door jamb and framing, as well as between the window frame and framing, is best filled with a putty material. Foam gasket is often used in these gaps, but is ineffective when trying to achieve high STC ratings. Putty material is the material of choice in acoustic labs across the country for sealing these types of gaps.
The SSP Putty Pad can also be used for several other applications. Basically, any gap or hole over 1/2" should be filled with the SSP Putty Pad when trying to achieve STC ratings over 50. Tear pieces from the SSP Putty Pad as needed or roll the pad to fill longer gaps.
