80 mil 36 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

Product is excellent in noise reduction, thermal reductions, and it’s easy to work with. It is aluminum backed so when cutting you can create sharp edges, just be mindful of that. The adhesive side is great as it sticks well but is also forgiving if you need to adjust. Very pleased with the results.

This is perfect for my needs. Priced right easy install.

Very easy to install and made a big difference in the sounds and road noise inside my vehicle.

this stuff is great, the price hikes SUCK, if the price goes up much more it will be time to switch brands again, MULTIPLE installations and ZERO issues, works better than you would expect, sticks and holds better than dynamat, seals up TIGHT, works well in sub enclosures as well as doors, roofs, trunks floors, puts more fun in driving and removes noise fatigue for a much more comfortable drive if you have complaints about the product then you did NOT prep your surface

Good quality stuff, at first I was very skeptical, but after installing the material the panels are hard as a rock no more rattles or panel flex. My muffler and exhaust system was flexing and rattling and I had cracked my previous muffler but after this it silenced everything. The bass funnels into the cabin more. The mat stuck on easily but it did have a slight tar smell hopefully it doesn’t get worse when it’s gets hot. 36 sq feet was enough to do 2 layers on my trunk lid and to do the trunk. It is a nice flexible material and I had no issues getting it to bond to the contours of my trunk.

Sticks well. Not as nice as Siless version. If I were buying again I would just buy extras Siless 120 mil, they are around the same price but the value is better with Siless's thicker panels even though you get less total coverage per pack. Can be cut to size easily, we used a box cutter which got a little gummed but but not too bad. we were able to get it in and around everywhere we needed to put it and it held up well as we were mashing it into weird spots. It doesn't smell hardly at all while being applied and once its on there is no smell whatsoever The product is good for what it is. 4 stars only because I think it gets oversold for how much this alone can do. We did notice a slight reduction in noise but nowhere near the multiple decibels we see claimed everywhere. If your vehicle is mostly quiet but just has that little bit getting through this will probably do wonders, If you have a vehicle where there's significant engine noise in the cabin you'll need more than just this to bring that down.

Worked well. I would buy these again. I have a loud exhaust and used these from the rear seat back. They are easy to work with. I cut to fit, peel the backing, set it on top of the kerosene heater to warm up. Then they just worked right into place. They are an aluminum backed tar substance that is fairly easy to work with. I would recommend these and would buy these again.

Awesome product. I lined the cab of my RV to cut down the road noise. Removed the seats and door panels, the job did take some time but well worth the effort. Good value and easy to apply.
