KILMAT 80 mil 36 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

Worked pretty well for quieting my car down. It’s easy to cut to size and to apply, and I didn’t notice any smell. Id say I went for about 60% coverage and ended up using about 1.5 of the 3 boxes I ordered.

Works as advertised!

I bought these for my noisy 79 Trans Am and they are great! Easy to apply and easy to cut. Drastically improved the noise level inside my car. Would definitely recommend.

First time using this and was very pleased. I made sure to degrease the floor and make sure floor was dry. I liked how the sheets were in manageable sizes and this was so easy to cut when I needed to trim off pieces. I didn’t cover every inch of the floor and figured even if there are small gaps it would be better than before. Very easy to use. One box completely covered the floor of my crew cab.

I just applied this to my 3rd Gen 2018 Toyota Tundra Crewmax, which has a big cab you should know and it sounds better and I can see some noise cancelling coming from this. I used 2 packages total and for my all my door interior panels, back seating and back panels and I need to order another set. There was a smell that lingers for a couple of days but it literally disappears after that! Every review made it seem like it was unbearable but truth is that once you get it applied just apply some air freshening deodorizer and itll go away within a few days. It sounds fuller and quieter. Everything on any new car, except a rolls royce I guess, gets a ton of exterior noise level! The adhesion is good as long as you got a reliable roller too by the way. I have yet to do my firewall, driver side and transmission/center console hump so thats next. If Im doing the headliner, Im going to consider doing a insulator and sound Deadened for that instead of the kilmat. And a note for anyone with open and spacious big cab or interior, please consider ordering more than just what they recommend on their sizing. I followed that suggestion and I really recommend ordering a couple more than expected. For Tundras probably a good 4 packages if you are doing all everything. And if youre on a budget so far this is the best way to do it.

Installed in all four doors of my double cab Toyota Tacoma. I covered as much surface area as I could reasonably reach, so probably 70% of the entire door since there are side impact bars, body lines, window mechanisms, etc. inside the door. I like very much that the back foil has bumps to make it easy to tell when it’s properly rolled down or not. In my case, I installed in the Texas summer so adhesion and flexibility were no issue. I also like that it didn’t leave black goo on my fingers as another brand did. The adhesive seems to be really good, too. The biggest (only?) challenge was getting it rolled into place because there’s not much room inside the doors. My hands were all banged up and bloody from sharp edges and screws and whatever all is hiding in there, but that’s not the mat’s fault. Once all was reassembled I went for a drive. All the way from idle up to 75mph there’s a definite reduction in road, tire and engine noise. It’s not magically silent, but you hear music better and can speak more easily with one another. I’m convinced enough that Im going to sweat my ears off to put this on the back wall of the cab and then put it into my other vehicle as well.

I completed a full replacement of the interior of my 86 K20. Once I had everything out of the cab, I cleaned the painted floor and put these squares down. I did not get meticulous and cover every single square inch of the cab floor but definitely got 99% of it just to the back wall of the cab. This box was more than enough and I still have about 1/3 or more of the box left. I went from a rubber mat to new carpet on top of this stuff and there is a noticeable difference in the sound level. Hard to say how much is from this and how much is from the carpet itself but the interior is much more comfortable now.

Used this to deaden some of the noise in my 2023 Polaris Ranger XP. Easy to use and it deadened some of the sound. I would buy again.

Being the first time I have used this I didnt know what to expect. Was it going to be hard to install? Would I hear a sound improvement? I was watching videos of people installing it and they said to let it heat up in the sun. There is a point when it gets a bit to hot and it flops around and is super sticky. I was putting this in the door panels of a 2019 Honda Civic 2dr. Not a lot of room to work with and it wants to stick to every little thing it touches. Not a bad thing but just takes more care to get it in there. I did the bottom 2/3 of the doors. Now when you tap on the doors its just a thud. Overall sound from the stereo was improved. The low notes are now MUCH cleaner! The bass guitar sounds like a bass guitar and not just some humming low note. Same goes for the bass drum. Much more defined and musical. I cant say anything about noise reduction from outside the car yet because I just havent driven the car enough. So for under $50 its worth it in my opinion.

This was really great quality insulation - stripped my car to the frame (removed trim and chairs etc) and adhered it to the frame itself. Easy to cut the pieces down to size with a simple box cutter (though will get gunked up over time with the black stuff inside). Put it down, kinda use a flat surface thingy (I used an old name tag from work) and then went over it with my hands (the heat from your hands helps). Now my car is clean, quiet and warm in this cold front were all having. Highly recommend if youre looking to quiet your car from outside or engine noises (Id say a good 20-30% decrease from before I did this). Very happy with how it turned out.
