Review: TRY ITTT!!!! - OK, first of all I've been professionally taking cars apart and putting them back together for the last 7 years as an autobody/refinish tech. You see some cars with little to no sound deadner and some higher end cars with lots of it. Eventually you come to see/hear/feel the difference this stuff actually makes for cars that didn't have it at all or have very much of it. We've always used the 3M sound deadner pads that are shiny, black, and come 10 large (19"x19") squares in a box. Did a 2008 Crown Vic with those, they worked well. Those are much thicker than this stuff and weigh a fair amount more. (NO, I'm not complaining about weight) I just always thought that if it was heavier it HAD to be better. Well, I'm working at a different larger shop now, and it would've been harder/more expensive to get the 3M pads, so I gave these a shot. I had to do a 2011 Hyundai Santa Fe for noisy/hollow sounding doors, a couple of which pinged like a drum head when they closed, thanks to the foam/adhesive breaking down on the diagonal support inside the door that the door-skin is bonded to. So, I did a few big strips, (it does not need to be completely covered!!) inside all 4 passenger doors, and rear gate. The stuff cuts good with a sharp box-cutter (watch the foil edges) Also, it sticks very well when pressed or rolled into place. I then added some Noico red foam to help with additional road noise dampening and insulation. I know some people complain about the "smell" but I never noticed it at all in the Hyundai or my 2018 F-150. This stuff worked great! got rid of all of the pinging/hollow sounding doors and it also gives you a pleasant increase in sound quality/bass response even with stock speakers! The Hyundai doors now sound like closing the doors on a car 3x its price tag with by doing that. They sound nice and solid now when they close. I also did all the doors on my 2018 F-150 with the other half of the box of this and the Noico foam, good results there too!! I will still have a small amount leftover that will go somewhere in the F-150 cab. Good price! Definitely recommend to get rid of hollow/cheap sounding doors or added for those looking for better sound!
Review: Good product - This material works great and is easy to install. I used a heat gun to heat it before applying to my 75 chevy floor, which made it plyable and easy to mold to the shape of the floor. Holds down great.

## Features

- Very sticky self-adhesive 80 mil automotive butyl and foil sound deadening. It is user-friendly viable material suitable for DIY installation. KILMAT is really efficient and easy-to-install
- Now the material is 1,5 times thicker that will get you 1,5 times more effective insulation. The thicker the material the more performance you get
- Automotive self-adhesive insulation consists of butyl. KILMAT sound deadening has a total weight of 0.5 pounds/1 square feet. This weight ensures optimum efficiency and sound insulation that could be possibly gained from 80 mil thickness material. KILMAT 80 mil is light weighted sound deadening material
- Audio insulation KILMAT has a special indicator as to if it is installed correctly. The special embossing on the foil must be rolled out till it is plain smooth, then you'll be 100% sure that the soundproofing is set correctly and professionally. The sound dampening material comes in handy size sheets which make it easier in terms of cutting and installation process

## Questions & Answers

**Q: Could anyone post a picture of the installed insulation?**
A: I'm pure sure anyone could do it

**Q: How many boxes i need to cover my ford transit 350 extended cargo van, but in a very strategic way.**
A: You would need 5 boxes of material to cover the floor (apply long narrow strips in between the ribs), double the layer on the rear wheel wells (from interior side), apply long narrow strips to the roof from the interior side and apply some to the wall panels, specifically to the sheet metal tiles in between the ribs-columns. You would need an additional box for the cab if you decide to soundproof it as well.  It is worth mentioning that you'd need to do 100% coverage on the floor, roof if you are after maximum effect as those are the most important areas.
Make sure to roll every piece of it with a roller and clean/degrease the surface prior to installation. Wear gloves!

**Q: Would this work under the hood?**
A: Kilmat has a working temperature from - 49 degrees to 212 degrees F with allowance for only short term heating of up to 392 degrees F.  
We recommend using our material when installed under the hood in combination with a hood liner type of material (acoustic foam) to protect it from excessive heat (if any) and to add the additional insulation.
The first layer that goes on a hood metal would be Kilmat 80 mil material
The second layer on top of Kilmat 80 mil would be hood liner type of material.
We are sorry, but we do not carry hood liner materials.

**Q: I have a 1968 Mustang the exhaust is pretty loud can I double the insulation how much less noise will this have on exhaust**
A: The exhaust on my '79 Camaro is pretty loud too behind 400hp. This 80mil should be thick enough. You'll want to cover 100% of the floor board and make sure you cover under and behind the back seat and also up the sides of the inner quarter panels. I used a precut heavy underlayment layer on top of this Kilmat, then the carpet of course. The layers I have tamed the exhaust decibels inside the car tremendously. My car's interior was never this quiet before the restoration.

### ⭐⭐⭐⭐⭐ Great Alternative to More Expessive Brands
*by D***N on March 2, 2026*

Excellent sound deadening with a good thickness. Made a huge difference in the sound inside my Silverado Crew Cab. The thinkness is easy to work with, and the quality of the adhesive backing is amazing. Once it's attached, good luck removing it. No smell that I could detect. The size of each sheet is perfect for door speakers.
