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

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.

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.

Works amazing just some places needed too be doubled up

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

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.

This product was very easy to work with. This is my third vehicle Ive installed sound dampening on. Ive used dynamat which works fine, but why pay more for essentially the same thing? This product comes in thin sheets. not a roll and can be cut with scissors. I preferred using a box cutter. Adhesion was great without Gavin to use a heat gun. I did use a roller though. This was installed on 2020 Cadillac xt5 on all four doors and the rear lift gate.

Decided to go with 50 mil Kilmat roll after doing extensive research and cost comparisons with other well known brands. It was a no brainer on paper. Pros: - Super easy to work with and extremely pliable. Can easily be cut with household scissors. - Does not have super sharp foil edges and can be applied with bare hands - Very well packaged and comes in 50 pre-cut rectangle sheets, which is much easier to manage than a giant roll - ZERO SCENT/VAPORS - Decent adhesiveness when applied to a clean surface prepped with isopropyl alcohol Cons: - Stuff is a bit thin. However, you get plenty of product so I applied double layers to all panels for essentially 100 mil thickness. I noticed a rather noticeable difference in tone when I knocked on the panels with a single layer vs. double layer Probably worth your efforts to double up the first time. - the square pattern application guides on the foil were a little bit difficult to press down fully with a regular roller. So I went over them as best I could with a roller, then used the back of the handle of a large flathead screwdriver which really flattened them out and gave me peace of mind Did 2 layers on both the inner and outer skin of the front doors of my coupe and still have over half of the product leftover. Stuff is really good and made a noticeable difference in my vehicle with just the doors done. Have not even touched the trunk yet. Rattles were cut down substantially and I can hear much more defined and fuller bass notes from my mids and subs. The front stage just feels a lot tighter and envelops the cabin. Tip: you do NOT need 100 percent application with these sound deadning tiles. 60-65% coverage on a panel is all you need. More than that and you are just wasting product and adding unnecessary weight. Would definitely purchase again.

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.

Have used these on multiple vehicles and am very happy with the quality and price point. They stick very well! I recommend getting a set of rollers to really put some pressure when installing. I lined my trunk/hatch area in my 07 Honda Fit and noticed it was quieter (even with the wind noise Fits are know for:) I follow it up with some sound deadening mat. Very happy with this product! Would and have bought again!

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.
