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

I upgraded my radio in my 18 Ram Quad Cab. This is one noisy pickup. A lot of sound from the 6x9s was just being canceled out and over powered by the road noise. This makes the treble really harsh and piercing. I could barely get the eq to make up for the noise. I used 38 of 47 sheets on the doors of kilmat. The difference is night and day. The doors feel more solid. They are heftier. The noise reduction is enormously significant. The harshness to my music is gone and the mids and lows are very pronounced now. Ill use the other 9 sheets to put under the carpet where the downward firing sub is and the rest under the carpet of the front seats. Great product with a better value compared to other brands.

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.

Bought this to sound deaden a few things around the house, ive used Fatmat in the past and this seems to be just as good i also like that it has those rectangular bumps to let you know if it was applied with enough pressure. Used to sound deaden metal cart for 3d printer, my kitchen sink and my stainless steel trash can would defiantly recommend to put some on the bottom and sides under kitchen sink it kills the cheap tinny sound when doing dishes

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.

This stuff worked as good as or even better than the stuff costing 5x this amount..

Looks great and works great. Husband loves his Christmas gift!

Used one kit to completely cover the floor of a Sierra extended cab truck. Covered floor and up back of cab. Still had about 4-6 sheets left over. Throughly cleaned the metal and this stuff stuck right on. Doing it in the sunlight let’s you contour the sheets to fit exactly how you need. Overall pretty good noise reduction. My truck is a duramax with 5in straight pipe and axle dump and the drone is significantly less than before.

Seems like it works. Did not check with a meter before or after but I feel as if the difference is somewhat minimal. I decided to buy and install this stuff on a Class C RV cab because of the intense amount of road noise. I realize that an RV is a moving house on wheels and will make all kinds of noise, but I really couldnt have a conversation with my wife when driving without yelling or hear the radio. I found killmat and decided to tear everything out and install these mats on doors and floors. I already had heat/sound resistant material in the doghouse from a previous install and do NOT recommend using this stuff in that heat. Post install drive seems like it reduced noise about 15 to 20 percent. Enough to have a conversation without yelling. My wife and kids say that they can tell the difference but Im a little more critical of my work. I also swapped out the crappy ford speakers with better speakers and can hear the radio fairly clearly. The difference is NOT night and day...it is more like night and early morning. It works but this is still an RV. It may work better in a regular vehicle. Was it worth all of my sweat to install...yeah, I think so.

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.

It works well
