This is excellent! I live in a townhouse which shared walls. The walls are very thin. I placed this in corner of wall in room and it blocks noise from adjoining wall. I'm going to try and find larger packages and buy more. I recommend getting this for noisy neighbors sounds.

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.

This stuff is great for clearance lights and making that pesky squeak quiet.

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

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.

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.

Rxcellent product
