2 Pack High Density Self-Adhesive Sound Insulation Acoustic Closed Cell Foam, 11.6 sqft x 0.4in Thick, 50+kg/m³ Sound Proof Padding,Fire,Water Resistant Acoustic Treatment Foam

Clean the walls well and be careful...the adhesive is VERY good. Easy to use and the room is almost completely soundproofed. It's great. Be careful.

This is a quality product and does the job that I intended it for most people use it for soundproofing in a car, but I put it underneath my cornhole boards to take away the thud and dead in the sound so I can play a little later at night. it does just that, just remember to use a roller to secure it tightly in the corners and center.

Used on the bottom exterior & interior of an indoor fountain (sits on tile) to help mask the hum of the pump. Not gone but definitely reduced, and the pump noise is now less than the water noise.

foam pad with a sticky backing, the foam is not a solid foam but still enough to hold its rigidity, i use it for sanding and need to keep it flat. So cut the sandpaper to your size stick it on the foam and the area of sanding isn't shaped like your hand or fingers. thats what i'm using it for

I bought this to add to the sound deadening underneath my new double kitchen sink. I cut and installed the whole roll and within hours it was pulling away from the underside of both sinks. I cleaned both sinks with mineral spirits and let it dry completely before I attached this black foam roll. They need to improve the sticky adhesive that they use. I had to use regular duck take to hold it down. The duck tape is the only reason it’s still installed. Without the duck tape it would fall off. Will not buy again.

The product do not block or diminish sound as advertised. If you need it for something else is good it has good material and sticks well .

I purchased this to absorb sound for a generator box I was building. The box was made with 1” foam board and I used this to stick in the inside. The sound db reduction was only 1 decibel in addition to what the foam board did alone (at 6ft). Within 24 hours it started to peel off. The sections that haven’t is because I used spray foam on the corners. I chose it because it not flammable. For my application it was almost a complete failure and didn’t reduce sound as expected. As this is rolled up the inner portion of the roll peeled first.

Really functional! I put them on the side of a loud mini fridge a couple months ago, and they seem to be holding strong except for the corner at the top, wanting to lift a little bit! It’s made a significant difference in the level of noise and I don’t worry about the heat of the side against the wall as much.

Très bon produit et colle très bien

Its ok, quality is good but cannot really say that it does block noise in the Pipe

Just don't buy it, it doesn't work.

Highly recommended for repairs
