Better than Kilmat
Material Type: 157mil Closed Cell Foam, Style: 157 mil 36 SqFt
Great adhesion, and you can immediately see the sound difference when you rap the area and compared it to another area without it. Also, very easy to cut and apply. Once on, you may not be able to peel it and reposition it, so be sure where you want it.
