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

I ordered 4 boxes for a total of 200 sq ft. I still have half a box left after covering the inside of my entire van with 2 layers. Its heavy but really high quality especially for the price.

It is easy to handle, easy to cut, easy to apply just over all easy. The hardest part is probably the assembly and reassembly of your vehicle. I used this for my 2022 Nissan Altima.

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!

Great product for what I needed for sound deadening the cab of my 1961 Ford Pickup project. Installs easily and quickly with no mess! highly recommend!

I have an old car from the 70’s and it has the normal rattles and such, well it did. I used this in my trunk and in my dash. I’ll be doing more of the car later. My main problem was in the dash, and that is all gone. My subs seem like they have more bass too. I’ll end up doing my doors and package tray with this and I expect to have extra, so I think it was a good purchase. I could smell it a little, but not bad. I sprayed it with some plastidip in areas that I thought might get more heat and maybe smell a little more in the summer. I’m not concerned however because once it has out gassed, it would not be an issue anyway. Really good stuff.

I really like this product, it was super easy to lay out and trim to fit pieces where full sheets wouldnt fit. I could of taken more time and fit it a Bit better but in less than 30 minutes I did the entire floor of a 06 crew cab gmc 2500hd. I have not driven yet for noise test but just tapping on the floor you can instantly tell it will be helpful. My factory mass backing had water damage so I liked this for noise reduction and getting rid of the padding.

I was skeptical about the sound deadning quality, but after i installed it i realized it work. You gotta cover the complete floor and rear wall of a single cab silverado, for it to be effective . Dont try and cut corners, remove everything and clean everything well so it will adhere to what ever your applying it too.

Works well, within its limitations. Its not going to turn your 90s tin can car into a modern lexus, but it was a pleasant change in my 2012 Miata, making everything sound more solid, the stereo sounds better, and marginally less road noise. Make sure to get the application roller tool, as its essential for proper application. One note, you dont need to entirely cover panels. One sheet or a large square on a panel will work 90% as well as covering the whole panel. The purpose of this is to dampen vibrations. It is not sound deadening mat, despite being labeled as such. For proper sound deadening you need something to isolate the sound. This is usually closed cell foam, or something like carpet padding.

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.

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.
