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

The product quantity was more that enough to cover 4 doors on a 2008 Tacoma and still had enough to cover probably another 4, had plenty left over. Did install on a 85° day and they adhere really well. Tried using gloves but its hard, easier if you dont use them. It did leave a light smell of tar for a day or two only. The doors do feel as if they close tighter but didt really notice a great difference in outside backgound noise. Speaker sound does sound better. Definetly not to be used as insulation, they feel hot to the touch as metal does but still do recommend.

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.

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.

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 :)

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.

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.

Covered a truck floor and back wall. Went on easy and made a noticeable difference in interior noise when knocking on panels. Project isnt drivable yet, so I cant comment on driving noise. Happy so far

1993 gmc yukon 2 door interior refresh project. 2 boxes of this product will get you the roof, side panels and 90% of the passenger cabin. Kilmat estimates 130 sqft for this project so they are pretty close. Ill buy another box to finish, then cover it with Noico 315mm closed cell foam sheets. This will be so much quieter and warmer in the Montana winters! Pointers: scrub the surfaces then go over with an alcohol rag then a tack cloth. Make sure its really clean. After laying down a sheet use a roller to really smash this stuff into the seams. No really, go over it again until all the little squares have been smoothed out. If you want, mommas rolling pin will work for the big areas. Next I suggest laying closed cell foam over the top. This will increase the sound deadening and help keep your car comfortable.

I really like this product, it was super easy to lay out and trim to fit pieces where full sheets wouldnt fit. I could of taken more time and fit it a Bit better but in less than 30 minutes I did the entire floor of a 06 crew cab gmc 2500hd. I have not driven yet for noise test but just tapping on the floor you can instantly tell it will be helpful. My factory mass backing had water damage so I liked this for noise reduction and getting rid of the padding.

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.
