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

The mats were very easy to cut up and install inside the interior of my car. Road noises sound muffled which is very nice and vibrations from the subwoofers have less rattle which adds thump and tonality to the music. This stuff is really great and idk if it’s just me but I love the smell of the adhesive, it made installing this very pleasant :)

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.

***update*** I updated rating from 1 star to 4. The smell was faint but did seem to go away. Car is in garage and hasnt been exposed to sunlight yet, but hoping there is no smell. So based upon reviews I decided to purchase the 50 mil x 50 sf package. My main concern prior to purchasing was a chemical / asphalt smell, and most people stated there was zero smell. Well, thats not true at all, there is an asphalt smell. I havent even peeled the liner off and I can smell asphalt coming off the sheets. After spending hours scraping off the old sound deadener and prepping the panels, do I really want to stick on this stuff? Also had a bad experience in the past using Fatmat about 10yrs ago, and that smell never entirely went away and was extremely strong after installation and actually gave me headaches for weeks. That purchase was also made based upon price. So now, trying to decide if I should send this back or not. Im leaning towards sending back, I cant deal with that situation again Id rather just spend a little more and get a real true high quality Butyl product instead of asphalt. You get what you pay for....

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.

The hardest part of the whole install was removing the headliner.

Work just as advertised and will definitely recommend 2 boxes and still need one more to finish my floor to have the whole truck done

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.

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 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.

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.
