  • Perfect!
Material Type: 157mil Closed Cell Foam Style: 157 mil 51 SqFt
I was nervous about doing any of this myself as I had never done it before. I highly recommend buying the rolling tool with it for the edges and seams! Super easy to cut to fit awkward places as well!

  • Easy to use and it works to cut the noise levels down.

  • Works great, note the word "finish".
Material Type: 157mil Closed Cell Foam Style: 157 mil 51 SqFt
Basically a large sticker tile, which makes it awesome. It's closed cell foam, thus great insulation for temperatures and noise. It is just a finish, not a real aluminum foil but more like a thin sprayed on paint. For best result, use on top of a noise decoupler like Dynamat/Kilmat/Amazons Basic. Both of these have properties that have worked well in my old vehicle that did not have anything in the roof, rear quarters, doors and floor. Or was very minimal. Picture is the cargo are for example, showing it bedlined with Kilmat, with some Siless closed cell foam insulation, topped with a 10mm foam rubber mat to protect it. ... show more

  • Worth the money.
Material Type: 157mil Closed Cell Foam Style: 157 mil 51 SqFt
Works really good against heat, light weight, easy to cut, sticks good, stretches a little to conform, definitely worth the money.

  • Super sticky and seems effective. Not exactly for sound.
Material Type: 157mil Closed Cell Foam Style: 157 mil 36 SqFt
Crazy sticky and easy to mold to curves/edges. This isn't that dense heavy weight rubberized mat, this is foam backed with that heat reflective material. Seems to work as intended, but I wouldn't say it dampens sound. This roll is massive and will cover a bunch of surface area. Cuts easy.

This product worked great and can tell the difference with and without it. Just needed to buy more to finish.

  • Siless for the win!!
Material Type: 157mil Closed Cell Foam Style: 157 mil 51 SqFt
I would say that this is a great investment if you’re having issues keeping your car, truck, or work vehicle! We put Siless in our work van and it makes a huge difference. I’ve also utilized similar products in aircraft and the noise reduction is also huge!

  • Sticky but not as bad as others indicated.
Material Type: 157mil Closed Cell Foam Style: 157 mil 51 SqFt
First time using an actual sound deadener product. I am currently in the process of applying. I like how easy it is to cut with scissor or a box cutter type knife. It will stick to your fingers but not so bad that I have had issues applying. My concern is how thin and lite the material appears. I will have to report back if it really helps reduce cabin noise. You really do not need a roller to apply I bought one but hardly used it. ... show more
