Sound Deadener for Cars, 157 MIL (4 mm) 36 sqft Sound Deadening Mat,Car Sound Deadening Closed Cell Foam & Heat Insulation Mat - PE Foam Sound Deadener Material & Heat Barrier

good quilaty

The product is of good quality and is true closed cell foam. see my pictures for the thickness. I am installing in my doors and trunk for car stereo. I think it is the best value for the money and the coverage of 36 square feet is amazing! the size is 1 long roll which you can cut to shape any way you need which is good. Installation is a breeze with the sticky backing to it. it makes the install go much faster then having to use your own adhesive. this is decent for noise level but is made for vibrations decoupling to stop rattles from bass. you could paur it with butyl sound deadener and you would have a really quiet cabin! I'm sure the noise level would be quieter just with this, but I'm using it to help stop resonant vibration of plastic trim pieces and smooth out my subwoofers bass. I am also installing butyl sound deadener on the main metal. 50% butyl coverage on metal, 60-70% coverage on inner plastic trim panels as well as the bottom of my false floor and also on top of my butyl pieces as a dual install. this will stop all flexing as well as help with cabin gain and make the interior quiet and your doors won't sound hollow when you shut them. This does also help some with outside ambient noise when used in tandum with the butyl. I'll use 50-72 square feet of this for my glb250 and the same for butyl. for the quality and money you cannot go wrong. you will be extremely happy.

Super easy to work with

Excellent service.

Why did you pick this product vs others?: I’ve used several sound deadening materials over the years — from Noico to Siless — and honestly, this one surprised me. I used it inside my doors and rear panels during a full audio upgrade on my truck, and it made a noticeable difference in road noise and vibration control. What really stood out was how well it sticks. Compared to Siless foam, this adhered way better, especially on slightly curved or uneven metal surfaces. I didn’t have to fight with it or go back and re-press areas — once it was down, it stayed down. Installation was easy with a roller and a heat gun for tighter spots. It's also noticeably cheaper than some of the name-brand options, which is great when you're trying to cover a whole vehicle without spending a fortune. Pros: ✅ Excellent adhesion — better than Siless in my experience ✅ Reduces road noise and vibration effectively ✅ Flexible and easy to work with ✅ Great value for the price Cons: ⚠️ Backing paper can tear if you rush the peel (go slow) ⚠️ Doesn't have brand hype — but still performs like a premium option

It is a very good product with many applications
