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.

The media could not be loaded. 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 what I was thinking. I've used insulation like this that was composed of heavy material, this one is not. This product must be for boats or airplanes where weight is a primary consideration and noise is not a problem. This is too light to have an effect on vibration or road noise. Absolutely zero difference. Anyways, I have both front doors full of the stuff and I'd pass if I were you.

I had a heavy duty stainless steel sink installed as part of a new countertop. However when they install the sink They used a silicone adhesive for the sound deadening mat under them sink but forgot to remove the silicone facing. So the sound deadening Mat did not adhere and stay attached. When removed there was a noticeable difference between the side of the sink with them deadening mat and the side without the deadening mat. I tried every glue instant grab possible to no avail. Then I found this item on Amazon. $14 for 6 or 8 pieces but I only needed the one and it was worth the price many times over if I had just had it to begin with. I use the old Matt as a pattern cut it out with a good pair of seamstress scissors tested the fit. Remove them film from the glue halfway touch the deadening mat under the sink then remove the rest of the mat and attached just by pushing it tight to the under sink. What an amazing difference in sound hearing the water hit the stainless steel sink in just a nice soft sound. That whole process took about 1 year with no help from the countertop firm. They offered no help or suggestions. It's one of the few products like other products you can find on Amazon. Fast delivery to boot. That's one thing we could never do without the internet.
