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

I used this material to line the cab of my RV. Cab noise was so loud before installing this, that trying to listen to the radio was pointless. Pulled up my carpeting, and installed these sheets on floors, inside the doors and inside the dog-house, and what a difference. The RV cab stays comfortably cool, no more hot foot on the passenger side. The road noise is markedly improved, and we can carry on a conversation without having to shout over the motor. Would highly recommend this product. Very easy to use and definitely worth it if you want to improve a hot, noisy area in your vehicle.

I prefer this to thicker offerings because it allows for flexibility. I can double up layers in more resonant spots and do single layers in spots that don’t need much help, or where I just want heat isolation. This product is not a noise isolation product, it is a damping material for panel resonance. It will do a little but if you are looking to substantially lower road noise level, this is not the product to use. With that said, it is the best damping material per sqft and price on the market.

updated. i tried partial coverage. one box 50 sq. ft. and put it on all the biggest metal panels. it was somewhat effective but i was not 100% happy with it. for best results go full coverage. at least 90%. i keep buying more and tearing my car apart again lol! just buy 150 sq. ft. and go nuts and cover everything! not just metal, on the back of all the plastic interior panels too. put a couple extra sheets in the middle of big panels to double up. i have a big 4 door camry so a hatchback could do 100 sq. ft. you can definitely have too little. but you cant have too much! the more you put on the better it works! i will likely buy another box to do the hood and front fenders in the future. i also found that it works great inside plastic speaker enclosures around the house.

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

I put this on my 78 F150 to reduce noise in the passenger compartment. I installed in the doors and on the floorboards. It is easy to install, high quality, and a fraction of the price compared to the big names in the industry. My doors now sound like a high end vehicle when they close and cabin noise has reduced significantly. Dont waste your money on the more expensive brands. This is just as good for a more reasonable price.

This product is very easy to install and adheres very well. My car has about 1/2 the road noise it did before. Its also one of the least expensive products that actually does what it says. Very happy with the purchase.

One box was more than enough to do an El Camino, including the smugglers box and ceiling. Easy to work with, but it will dull a scissors quickly so he was a good one.

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.

Very impressed with the performance of this mat, especially for the price. I installed it on the floor and rear of the cab on a 2006 F350 6.0 Powerstroke. I still havent finished the job but Ive heard enough to rate the product. I plan on doing the doors and ceiling tomorrow. I started the truck just now. This is without the factory carpet and pad installed. Without the boot on the floor shifter. Without the seat installed. The cab noise has been significantly reduced. Night and day difference. This is the most affordable mat I could find and absolutely will be buying more for two other vehicle projects I have.

Works perfectly
