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

It works well

This product was very easy to work with. This is my third vehicle Ive installed sound dampening on. Ive used dynamat which works fine, but why pay more for essentially the same thing? This product comes in thin sheets. not a roll and can be cut with scissors. I preferred using a box cutter. Adhesion was great without Gavin to use a heat gun. I did use a roller though. This was installed on 2020 Cadillac xt5 on all four doors and the rear lift gate.

Ive installed in my 87 s10 blazer, made a huge difference from what It had before. Took the vibrations out and did quite down a bit. Which is why i also installed in my 82 c10, I installed with a closed cell foam and i feel this combination worked the best . for a truck with a blown 383 3inch straight thru turn down exhaust set up , it made a big difference. Just recently did half my new silverado , definitely a must if youre doing any audio. Plan on installing closed cell foam also. Also sticks well so far, after you roll it I dont expect it to come back off easily.

You get a lot for what you pay for. Noise is cut down by at least 60%. Highly recommended. Nice product. Will definitely use again.

VALUE: I used Dynamat Xtreme (~67mil thickness) on my outer door skins on my 2012 Mustang, but I wanted to try something less expensive for the roof. While Dynamat Xtreme costs about $4.44 per square foot, a 50 square foot box of 50Mil Kilmat is $1/SF. I feel like Kilmat gives you about 60-70% of the effectiveness of Dynamat, but for 23% of the price. SMELL: The material had a pretty noticeable odor after just opening the box. I installed this on sunny 95°F day, which created a very strong smell with the doors and windows closed. The smell was gone after airing out the car for about 3 hot days. It didnt seem to linger in my cloth seats either. INSTALLATION: I really enjoyed working with Kilmat. The embossed rectangles make it very easy to cut out specific shapes without measuring. It also makes it very easy to see where you need to use your roller tool to press down the material. Its thin enough to bend into tight spaces and the foil stays well attached to the butyl. WORD OF CAUTION: Whatever product you go with, make sure to avoid asphalt containing products. They give off a horrible smell and they have potential health risks. As far as I can tell, Kilmat *does not* contain asphalt. UNDERSTANDING DEADENING SHEETS: - Layering butyl sheets isnt effective. 2 sheets of 50mil thickness is much worse than a single sheet of 100mil. - Kilmat and similar products mainly dampen the vibrations of whatever its applied to. It doesnt do a great job of blocking sound waves or as thermal insulation. Its best applied to large, thin sheet metal thats prone to vibration.

Installed in a 2021 Dodge Challenger and has helped with rattles and hollow sounds from all locations in the car. Easy to install. Make sure you measure several times and cut once. Save all your scraps they will come in handy for those hard to reach locations.

1993 gmc yukon 2 door interior refresh project. 2 boxes of this product will get you the roof, side panels and 90% of the passenger cabin. Kilmat estimates 130 sqft for this project so they are pretty close. Ill buy another box to finish, then cover it with Noico 315mm closed cell foam sheets. This will be so much quieter and warmer in the Montana winters! Pointers: scrub the surfaces then go over with an alcohol rag then a tack cloth. Make sure its really clean. After laying down a sheet use a roller to really smash this stuff into the seams. No really, go over it again until all the little squares have been smoothed out. If you want, mommas rolling pin will work for the big areas. Next I suggest laying closed cell foam over the top. This will increase the sound deadening and help keep your car comfortable.

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

It removed almost all of the resonances inside my TrailBlazer SS and quieted the ride overall. I did use two boxes to get everything, including the inside of the car roof and inside wheel wells and door banels. Lining the overhead made a huge difference, I definitely recommend doing this. My AC seems to work so much better now and the car just does not get as hot inside, at least not anywhere near as bad as it used to when left sitting in the sun all day.

I used these in my 2009 Jeep Wrangler all on the interior and it actually did a great job reducing noise. I used about half of the whole box covering the tub of it and the inside of the doors. It made the ride quiet and my sound system better because of the change of the acoustics. Takes time to install but is easy to cut with a stiff sharp knife. Buy a set of rollers with this though to make installation easier. Also, it takes about a whole day to install it. I have some left over I will probably use in a second car.
