Solid quality and good price
Size: 10 sqft
I bought this for my custom built camper van and it’s been great so far. For $24, the amount of coverage you get is totally fair, and I’ll probably grab a second box to finish everything. It’s easy to install with just scissors and something to press it down, and making quick cardboard templates really helps for tight spots. The adhesive is insanely strong, so once it sticks, it’s not going anywhere (just don’t let it stick to itself). Keep in mind this is sound deadening, not full soundproofing, but even with partial coverage I can already hear a difference in reduced road noise and vibrations. I’m using this as a base layer and plan to add soundproofing on top, and so far I’m really happy with how it’s turning out.

It's a job but totally worth it
Size: 36 sqft
Pack a lunch when you tackle this project boys.. its a doozy!! Month in going great so far definetly did what I purchased it to do. 2000 chevy with two p3 10s every bass drop sounded like an old firebird with loose trunk bolts. Threw this on the back walls floor underneath the speaker and the doors.. all that energy is now in the cab with me instead of getting lost in rattling metal!! Love it!!! Left a few pieces outside after I was done rained like hell on them so water doesnt hurt this stuff at all or direct sunlight in south mississippi.. good stuff pick this up and make them systems thud instead of rattle!!! You wont regret it!! I didn't!!

This works very well to put down road noise. The difference was immediate in my van. I was shocked it made such a difference.

Reasonably priced sound deadening
Size: 18 sqft
Easy to cut with a carpet knife. I used a heatgun to make it stickier and more moldable. The foil isn't so thick that you risk cutting yourself like some Dynamat variants.
