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

For those looking for a good low-cost alternative to Dynamat, this is acceptable. I used both Dynamat and Kilmat on the same build. The Dynamat product was the Dynamat Xtreme. In contrast, the aluminum on the Kilmat is thinner and the butyl material smells A LOT like roofing felt... like EXACTLY like roofing felt -- definitely a bituminous odor. It is not overwhelming. I could only smell it with from about 2 away at normal temperatures By comparison the Dynamat Xtreme has ZERO odor. Nothing. The good thing about the Kilmat is that it sticks very quickly (used a heat gun to promote adhesion due to cooler outdoor temps but really did not need to) and the embossed aluminum makes it simple cut straight with one mark. Also, the packaging says it is made in the Russian Federation... so, those folks have a lot of experience silencing things so this will likely work very well. I just hope its not made out of Chernobyl chunks else my build will put a new meaning on the term radioactive.

This is a lot of material and it goes a long way. I did the back wall of my truck and have at least 35 sheets left. I may add more elsewhere. It cuts super easy with scissors or a razor knife and molds into place. I got the roller tool which was great for flat areas and found a screwdriver handle worked great for smaller, hard to reach areas.

My 2016 GMC Yukon XL has over 153K miles and was starting to exhibit a lot of unwanted creaks, rattles, and other unwanted noises. I applied about 10 sheets to the floor pan in the rear cargo area and under the second and third row seats and WOW, what a difference!! It tamed almost all of the rattles and quieted the ride overall. Im going to order another box or two and get to work on my Transit van (350HD,) 2014 Prius, and 2019 Tesla Model 3 next! Absolutely 1000% recommended!!

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.

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.

Honestly works better than expected, adheres good once you use the correct roller. For better sound deadening you will want to double it up but 1 box gives you quite a bit. Thanks!

Great product! I use it in all of my cars!!

was amazed at how much one box can cover, the parts I covered on my car definitely make it feel more solid and less like a tin can. For noise cancellation, I do not notice much of a difference but I love how solid it makes my car feel, and when lowering the hood it is definitely canceling all the noise of a thin piece of metal shed door closing noise that happened before, now it sounds sturdy and silent. some weird rubber smell at first but did not linger. easy to cut with scissors or with a razor, I am living in a desert environment so the heat of summer helped the stickiness/ adhesion. would recommend.

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!

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.
