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

Ive built motors, done extensive bodywork and made all kinds of modifications to vehicles. Sound deadening is by far my favorite. The install isnt fun by metric. First, uninstall your entire interior. Clean the inside of every panel with isopropyl alcohol. Grab a rolling pin (they make specific tools for this), cut your acoustic mat and be prepared to spend the next 8 hours in a sweaty and cramped position. Cover every square inch you can- it really does make a difference. Put in the hours here, and enjoy it for the rest of your vehicles ownership. Not only does this make your ride quieter, but it feels more luxurious, too, since the deadening material has the additional effect of quieting down interior trim rattles. My old Ford Ranger is now quieter on the highway than my BMW 5 series (seriously!). The 50mil Kilmat is not the thickest option, but it is an outstanding value when Dynamat will sell you the same basic product (foil-layered tar) for twice the price.

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.

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

Ive bought this twice now for two separate restore jobs. Its pretty easy to apply to the metal. Its pretty easy to position where you want it and then cut out the areas for the seat bolts and seat belt bolts. If you prewire the stereo wires to the back, this stuff will also cover up those wires pretty well. buying the roller was a waste of money. I stopped using it and just used my hand to press this stuff down since the floor of the truck isnt smooth and the back is that shiny slick foil stuff. I also noticed that when I had small areas of over lap, like when I was setting in an inside corner with two pieces, if you press a little harder you can hardly tell its double thick-just in case youre wondering if it could make the carpet bulge a bit, it doesnt.

Used one kit to completely cover the floor of a Sierra extended cab truck. Covered floor and up back of cab. Still had about 4-6 sheets left over. Throughly cleaned the metal and this stuff stuck right on. Doing it in the sunlight let’s you contour the sheets to fit exactly how you need. Overall pretty good noise reduction. My truck is a duramax with 5in straight pipe and axle dump and the drone is significantly less than before.

Great product! Like the results

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

Wear gloves. Very sharp edges will cut you.. not may, but will. Easy to work with, very malleable. Not so sure it improves the sound insulation that well, but adequate.

Covered a truck floor and back wall. Went on easy and made a noticeable difference in interior noise when knocking on panels. Project isnt drivable yet, so I cant comment on driving noise. Happy so far

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.
