Acoustical Putty Pads - Moldable Soundproofing Pad - Fire Stop for Electrical Boxes Outlet Putty Pad, Highest UL and STC Rating - Size 7 x 7 - Pack of 3 Putty Pads - Made in USA

These worked great! I used them on new outlet boxes to help reduce noise, and they performed well. They’re incredibly easy to install—just wrap them around the electrical box, and they stick securely in place. I highly recommend them, especially if you’re looking to soundproof a wall, office, or any space.

When the idea of sound proofing is the issue…these cover the outlet boxes. That’s not for everyone, but for me, my application, they come in handy when I was attempting to seal sound into one space. Work as designed and easy, if not sticky, to install. Commercial electrical folks hadn’t really seen this in home design. Easy to install on a new build.

Very useful

I haven't run any tests to see if it made a difference since the room was just finished, so I had nothing to compare it to.Does give me piece of mind that if any sound does come through the outlets, it's not for a lack of trying.

Easy to use. HVAC, plumbers, and electrical trades all needed this product at one point or another. The inspector is happy with it too.

Easy to work with and cut u can also overlap multiple

Work as described. Hope I never need to review post-fire! Can’t really say if they reduce noise. I can say I don’t hear anything so they probably help but I over-built this project so hard to say what was the key. When spending this much money on a wall, this was cheap piece of mind!

No noticeable difference, plus 2-day shipping (Saturday arrival) turning into 4-day shipping. Disappointed in both aspects.
