Car Sound Deadening Mat, 197mil (5mm) 8.7 sqft Closed-Cell Foam Car Insulation Material, Aluminum Foil Heat Shield, Waterproof Self-Adhesive Sound Deadener, 8 Pcs

Really nice quality. There are strings woven into the top along the foil. Easy to work with. The backing peels off smooth and usually in one piece. Great value

For $14 for 8.7 square feet, this was more than enough to cover the important parts of the trunk of my 944. You DON'T need a roller to apply this, just strong hands and a well prepped surface. I vacuumed, lightly washed, then used 90% alcohol to clean the surface before applying. I could have used more and covered every inch, but there is diminishing returns in doing so (especially on a budget, or with a lower wattage sound system in my opinion). If this stuck as well as it did for me in a 45° garage, then it should stick just fine for you too. I will say, it is a little cheap feeling, but for the price I can't complain. There is an audible difference when knocking on the panels this material is applied to. I'm not a professional though, and if you're an audiophile, there are better options (but prepare to empty your wallet). Not sure I would do an entire vehicle with this material, but it is a great supplement.

I wanted this product for heat and sound installation. Worked well for my application of insulating Jeep floorboards. Easy to work with. Good adhesion. I may have went for a little thicker material. But it's better than only carpet. That's what Jeeps have so it worked great for me. Good value for the money, I like the size of the squares since I needed to do a lot of trimming anyway.

Was almost enough to do my full trunk on my 2012 civic si. I have exhaust and a subwoofer that were making a lot of rattles and drones in the trunk. Took everything out and covered about 70% of everything including the wheel wells and the rear deck support, even put some under my spoiler and behind my license plate. Now, quieter ride and no vibration from the trunk inside OR outside the car even with bass cranked up. This is a great product and I would definitely recommend.

Not exactly sound deadening but rather foam, good cutting. Not sure about heat isolation.

Simple and effective.

Performed as promised

Has a good thickness to not cause any clearance issues in the door panels during installation, provided a good amount of sound deadening, atleast for the cost. The amount came with enough to cover both front doors, on my small truck, with some to spare.

Lo usé para aislar la pared trasera de una pick up por cuestiones de audio

Very sticky. So far it absorbs loud noises in the car very well. Thought I wouldn’t have enough sheets but I actually have one left over.

Hace el trabajo, sin esperar mucho.

Works well. Easy to apply. Achieved a significant noise reduction in my work van and even the insulating factor to keep the cold out is an added bonus.

It's actually a pretty good sound absorber and vibration absorber for its thickness It sticks well it peels well You might want to order two packs I found this stuff easier to use than anything else when it came to stuffing small areas in the car because if it's flexibility and ran out of it faster than I expected
