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

I had the rollup door on my Step Van removed, and replaced with diamond plate aluminum on steel studs, as you might imagine, this transmits sound pretty well. So I had Kilmat installed between the studs. If you knock on the back wall with your fist, it sounds like a dull thud on the inside rather than a tinny clang. Perfect.

This product worked great and allowed for ample time to make fine tune adjustments before adhering and the dimpled grid pattern helped with cutting so as not to waste time marking lines as well as allowing for expansion on curves and contours. This size works out perfect on hitting the sweet spot for efficiency and minimal scraps that will also get used along the way.

Wifes 2015 jeep wrangler unlimited always felt a bit overly rough. Not much has changed for jeeps since the 60s... ride is rough, noise levels are off the chart. Nothing about the jeep felt like a modern vehicle. After a recent drive we decided to change that. I ordered this product to try to reduce some road noise. Install was easy, cutting the product with a simple utility knife. Place and roll. The rubber under the aluminum reminds me of what you find inside door panels, holding the plastic film in place. Super sticky, forever flexible and messy... if you find it on your knees afterwards lacquer thinner will remove it. Overall install was easy, rolling all of it made my hands sore the next day. Loved the look of all the foil lined floor. I have not driven it since install, but the wife reports great improvements. Stating it feels like it rides smoother. Sounds much quieter. Shes happy, so Im happy.

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

***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....

Used this on the inner firewall, front floorboards and then sparingly under the seats and middle row of my 2000 Excursion, 7.3L diesel. The beast is now tamed slightly and reduced my noise by 6-10 db in various driving conditions, measured using phone noise apps. There is enough to do two Excursions if you buy this kit...

Girlfriend and are I doing a mild camper build in our 06 E350. Were not going to really be living in it and most trips will just be 1-3 day ventures or for concerts. I also have everything easily removable so I can still use it to haul stuff. With all that I couldnt really be bothered for the 80mil for the large price difference. This does a great job. Its also incredibly easy to work with to cut around corners. We also used it to go over holes in the sheet metal on the sides after we packed them with insulation. The floor in the van has the kilmat down first then furring strips to balance the ribs with the foam board insulation then the plywood base to vinyl. With so much else going on top - the 50mil is the perfect thickness in my opinion for a van floor if thats your purpose with it. If you have the extra money and are super concerned with outside noise then Im sure the 80mil is just as nice to work with.

Excellent product I would buy it again

Easy to apply. Works as well as higher priced butyl sound deadener. Make sure to use a roller for best results.

Works amazing just some places needed too be doubled up
