KILMAT 50 mil 50 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

The road noise and overall tinny sound of closing the doors, trunk, etc. on a 2008 Accord Coupe got me to searching for a solution. Installed this stuff everywhere - on the floor, inside the doors, inside the trunk, on the ceiling, and on the rear-fenders (from inside; theres an opening under the trim). We also added Noico adhesive foam to further control road noise. It made a huge difference and the car is much more pleasant to drive on the highway now. Also, closing the doors now makes a reassuring, solid thump. Note: Handling the headliner to remove it killed the foam under the cloth. :-( 11 years of baking under a black roof, in the Texas sun, had weakened the foam. It crumbled from the handling and the liner started to sag in just a couple of days. Ugh! Pulled out the headliner and had it recovered at a local shop. Had I known this was a possibility, I might have left the ceiling alone! That ended up costing an extra $125 ($250 if the shop also did the remove and install of the headliner).

Great product definitely helped quite the cabin! Even put some under my hood still need to do the front! (2015 ford focus hatch back)

Love this stuff, so much cheaper than dynamat and no difference in quality. Super easy to cut, easy to roll down(with the right rollers), molds amazingly well around anything, and deadening quality is awesome. No complaints what so ever. There’s a reason why it has thousands of good reviews. Also 50sq ft did my entire trunk even to sides and double layers on my trunk lid and still had a bunch leftover. My trunk is kinda small it’s a 2013 Cadillac ATS but considering how much I had leftover 50sqft will cover the biggest of trunks and I assume be able to double layer the main parts of the lid too. Even did my license plate!

Bought this to sound deaden a few things around the house, ive used Fatmat in the past and this seems to be just as good i also like that it has those rectangular bumps to let you know if it was applied with enough pressure. Used to sound deaden metal cart for 3d printer, my kitchen sink and my stainless steel trash can would defiantly recommend to put some on the bottom and sides under kitchen sink it kills the cheap tinny sound when doing dishes

This product likely sat in a hot warehouse, and does not work as intentioned. It has an adhesive side, with a covering paper, and then it has a paper that you should be able to peel off the front side of it, but only one sheet out of the entire box worked like that. The rest were all stuck together

I almost went the poor mans way and bought Frost King Foam Duct Insulation, but then I saw this Kilmat sound deadening was about the same price as the Duct Insulation. Using prime, I ordered and received the package the same day. I found it was easier to work with this material with my bare hands as using gloves the adhesive stuck to the gloves making it difficult to install - once I took the gloves off it was much easier to work with the material. I also found it to be easier to use a good pair of scissors instead of a straight edge razor - the material is thin enough to use scissors. It was a cold day outside and when the temp dropped below about 42 degrees the kilmat material became much harder, so recommend installing on a day between 50-70 degrees outside. Also, the foil liner wasnt too sharp, I didnt have to worry too much about cutting myself using my bare hands. As far as it doing its job as a sound deadening material? I installed these in a 2018 Jeep Grand Cherokee, and I can definitely tell a difference on the road noise, especially on the highway. Its probably a good 25% quieter, if not more. My doors feel heaver, have a nice THUNK when I shut them, and sound solid when I tap the doors with my knuckles. I replaced my speakers in my doors at the same time and I am very happy with the results - no rattles and great sound. I did two layers - one on the outside panel and one on the inside panel - maybe overkill, but I received 50 square feet, which was enough to do all four of my doors doing double layers. This is A+ material.

This product worked great and allowed for ample time to make fine tune adjustments before adhering and the dimpled grid pattern helped with cutting so as not to waste time marking lines as well as allowing for expansion on curves and contours. This size works out perfect on hitting the sweet spot for efficiency and minimal scraps that will also get used along the way.

Looks great and works great. Husband loves his Christmas gift!

Ive used other products before - Dynamat, second skin, etc. They worked well, but were $$. This product is cheaper, perhaps just slightly less thick - though, not by much. It also sticks well and seems to quiet things down quiet a bit. Frankly, you can almost double it up and stay under the price of the other leading brands. I would suggest wearing gloves. The adhesive doesnt come off, but the material will slice your hands up - like paper cuts. Not a lot of fun. Aside from that minor gripe, the product really is a great value!

This stuff worked as good as or even better than the stuff costing 5x this amount..
