2 Pack High Density Self-Adhesive Sound Insulation Acoustic Closed Cell Foam, 0.4" x 12" x 71", 10 mm Thick,11.6 sqft Sound Proof Padding,Fire,Water Resistant Acoustic Treatment Foam

I used this to put around the motor and part of the piping of my radon mitigation system to suppress the constant annoying hum I could hear in the room closest to it. This stuff did the trick. I can barely hear any sound from the motor now. I will have to wait and see how it lasts, but it did have an immediate effect. The adhesive was very sticky and adhered well to the motor housing and plastic pipes. I did take the precaution of putting on some electrical tape to hold it in place just in case the adhesive starts to loosen. If the material doesn't last, I will update my review, but for now the material couldn't be doing a better job. I would recommend this product and would buy it again if needed.

Why did you pick this product vs others?:Cost and form were right for my application.Ease of installation:Very easy to cut, peel and apply to surfaces. The 1”x1” grid on the peel-off backing was particularly helpful.Works well:I used it to reduce the noise of my dish washer by lining the walls and top of the under-counter space where the unit sits. I didn’t take before / after noise measurements, but the sound reduction is significant.

I used this above the cab headliner in my Sprinter, to cover up the bare metal. Two goals - reduce condensation on cold days, and to reduce sound. It works for the condensation goal. It's hard to tell if it works for the sound reduction goal, as I put a lot of other insulation in the space up there as well. But getting rid of water dripping down from above was worth it.

Trash! Lasted 2 days then they all started peeling and falling off. The back of the pads barely even had any stick adhesive left so couldn’t even put back up. DO NOT WASTE YOUR MONEY!!!

Purchased this for sound equipment, once applied, it shrunk. Very adhesive though, which is nice but just wish it stayed in place.

This stuff is indeed heat tolerant. Tested in my oven to 190F with no issues.

Fast service. very happy with item. Everything as advertised.

I bought these to put on the back of my front door in my condo. There are only a few units in my building and most of my neighbors are single adults, so it’s pretty quiet most of the time. And inside the units you barely notice other people live in the same building.. the problem isn’t being bothered by others noises, it’s that the front doors are like an open window to the hallways and as soon as you open and walk in the very front door of our building, you can hear everything if anything is going on inside a units. The sounds travels crystal clear even if you have tv or music playing at a low volume. It broadcasts your words .. so any one in the hallway can hear every bit of your private conversations.. it’s So quite inside the units, it’s easy to forget how easy the noise travels through the hallway, untilYou’re in the hallway and the neighbor is home just existing and you hear every little sound to remind you.I bought these thinking it would be a great idea to cover my door completely with the pads to block some of the noises from going into the hallway…. Well the 2 rolls weren’t enough to cover the entire door. Had To order another role. Then not even a week later our dog ripped up the entire bottom Half of the padding off… we started putting a Baby gate to keep him away from the front door if we left. Ordered more roll. reapplied more padding….It doesn’t keep any of the sound inside … IWent downstairs to get the mailAnd I could hear the tv. I left my phone playing a video and walked back in the hall, completely closed the door and had a door sweep installed… I hear it all. Perfectly.. it didn’t block any of the noise. Not one bit…This whole experiment was a complete waste of money and didn’t help fix my problem.. I wouldn’t buy any more of this for sound proofing purposes.
