Metacaulk FRP Sound Rated Putty Pads stop the transmission of sound through electrical outlet receptacle boxes and light switch boxes.  Sound Rated Putty Pads are commonly used in soundproofing a wall or ceiling to block the passage of sound waves through an electrical outlet or light switch box.  When soundproofing materials are used on or inside a wall structure, the electrical outlet boxes and light switch boxes are usually left untreated and become sound channels which greatly reduces the STC rating of the structure.  Metacaulk STC Sound-Rated Putty Pads when installed properly will maintain an STC sound rating of 60! (UL441 per ASTM E90) 

Metacaulk FRP Putty Pads are also used in firestop applications as well.  During a fire, the Metacaulk Putty Pads will expand into an insulating char (over 220° F) and fill the void in the wall to prevent the passage of smoke and fire. Just one intumescent putty pad will provide a 1 to 2 hour fire rating!

    Easy Soundproofing for Elec Boxes

    Posted by Matthew H. on 7th May 2020

    Bought these to use on switch, outlet and light boxes in a basement recording studio. Very easy to install. Multiple pads can be combined for use on larger boxes such as double/triple gang switches.

    Blocks sound through outlets

    Used these putty pads to seal off the outlets and light switch in soundproof walls. They stuck well and were easy to mold around the box.
