BXISoundproofing Closed Cell Foam - Self-adhesive - Great for Noise & Thermal Insulation - 16'' X 12'' X 1.8'' - 2 pack (Gray)

These look exactly like the pictures and work as described! I am using these for both soundproofing and reducing noise pollution inside a room. I placed these as a top layer (I had a few more underneath it) on my hollowed steel apt door, and it blocks out the outside. In the music room, I used them on the wall by itself, and it blocks out all reverberation; removing the echoes like it's supposed to and absorbs the sound easily. They're expensive and worth it, and one of the few foams out there that is multi-use. The material is strong, very dense and of superior quality construction. Did I mention how much I love these and can't stop buying them and trying to redecorate my whole room with them only? :) Hope this helps. Stay safe everyone.

Foam breaks apart, not a solid product at all. Would advise staying away

The two pack (together) stopped all the vibrations and noises made by my sub-woofer. Best purchase for my issue.

My room have a sliding door in my new apartment, and there was a huge gap which basically let through any sound coming from the kitchen. I bought this product and was skeptical that it could change anything, but oh my did it work! It now block sounds like if I had a real, sealed door. Cutting it was messy and it is by no means a clean finish, but it functions very well (I'll paint it white eventually).

Easy to use, good adhesive that you can remove and read attach to window or wall and it will still stick without leaving behind adhesive.The issue is they dont sound proof as well as I had expected.
