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

Ive done all sorts of upgrades/enhancements to my cars over the years, and installing sound deadener has been the most transformative. Sure, upgrading the stereo/amp/speakers all at once is hugely transformative, but its also expected to make a huge difference. The reason I say sound deadener is more transformative is that it improved things in many unexpected ways, on top of the expected reduction in road & mechanical noise. Background on my vehicle: - Medium sized pickup truck with extended cab - 2006 but only 40,000 miles, so enough miles to develop some rattles - 4 doors (2 normal, 2 smaller) - Smaller doors provide access to extended area for storage or jump seats I took the driver/passenger and jump seats out but only moved the carpeting out of the way vs fully removing. This, and because I didnt remove the center console, meant that I was able to cover the sides of the drivetrain well but not the top . In my truck, most of the mechanical noise comes from the engine, not the drivetrain. What I covered with 72 sq ft of 80 mil mats (i.e. purchased 2 boxes of 36 sq ft): - 4 doors - Rear of extended cab (area facing bed) down to the floor - Ceiling - Driver/passenger footwell up thru firewall - 3-4 wide area running between seats and doors from front to back - 2/3 of area below drivers seat (was too lazy to remove passenger seat again just to apply a single sheet) - 1 sheet of mat leftover I was very thorough. I removed the speakers in the doors and covered the area behind them (I also installed speaker baffles, which improve the sound quality and provide some sound deadening qualities). The rear doors have built-in pocket storage areas so I ended up covering the exterior metal panels of the doors and the some of the interior metal panels. Maybe overkill, but those doors were also the source for a lot of road noise. Expected improvement: significant reduction of road and engine noise. This stuff delivered the goods. My 9 y/o immediately noticed the difference and said something before I could tell her I was done. And this was on city streets, so not even highway. Its that noticeable. Hands-free phone calls, music, talk radio, you name it, all sound much cleaner, crisper and without having to crank it up as much. Unexpected improvements: - Doors close with a more solid feel - Near silence when going over potholes and changes in pavement - Sensation of that I installed a new, more sophisticated suspension because everything feels tighter and smoother All in all, money well and one weekend well spent. Installation tips: - Run a small heater if installing in temps below 60 degrees. The mats will adhere better. - Buy the metal rollers to make sure the mats are completely flat and fully adhered. - Before removing the paper backing, put the mat into the desired location and press hard on the areas that need to be accessible (screw holes, wiring, etc) to create an impression. Then use exacto knife or razor blade to make the opening marked by the impression. Be sure to double check all access points twice so you dont find yourself all ready to put everything back together and you have to find the one you covered. For rubber gasket access points, I cut a path around the edges so you can remove the gasket, but theres still mat on the bulk (center) of the gasket.

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.

I used this for sound deadening in a 1965 Mustang restoration. The sheets are somewhat compliant and very easy to install. I immediately notice the deadening effect as the metal drum effect at sheet metal panels was well damped. I have not run the car yet, so do not know about lasting adhesion, but it seems pretty tight.

We ended up buying 6 boxes total of this and used on the inside of a Tahoe that is being restored

Very easy to work with and great adhesion. You will need the Norsmic roller to make this job a success. No smell at all. Installed in the rear trunk of a 2015 Kia Forte which sits low to the ground and absorbs a lot of road noise. This quieted things down I would say 90%. Makes for a quiet ride and helped with sound quality as having a subwoofer in the trunk it kept any rattling from happening. Perfect purchase, I am very happy

OK, first of all Ive 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 didnt have it at all or have very much of it. Weve always used the 3M sound deadner pads that are shiny, black, and come 10 large (19x19) 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, Im not complaining about weight) I just always thought that if it was heavier it HAD to be better. Well, Im working at a different larger shop now, and it wouldve 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!

Great Product. I was replacing the headliner in my Monte Carlo SS and replaced the original thin felt with the Kilmer 80 mil Mats.

Easy to use

I was doing 4 doors and the liftgate, so I only bought 1 box. I didn’t do 100% coverage on the liftgate, but fairly complete single layer coverage on the inside of the door panels (backside of the exterior panel) as well as some of the interior part of the door panel for the 4 doors and had 1/2 a box left over. Used a utility knife and cutting board to cut the material easily. It was a warm FL day so it was easy to roll the material onto the panel with good adhesion. To help cut pieces for odd shapes areas, I put a piece of backing paper in the space and folded or marked it for the right shape like a template. Sound deadening was immediately noticeable, reducing road noise, making the speakers sound much better, and the doors sound more solid when closing them. For even better sound reduction i would suggest pulling the headliner and do the roof too which is thin sheet metal. Maybe I’ll do it in the future. Overall, happy!

Got this to reduce trunk vibrations from bass. Wasnt expecting it to cancel it completely. I was surprised with how well it actually did though. After reading reviews of other more expensive products like Dmat and 2ndSkin. But this product also had good reciews as well so bit the bullet to save some cash and glad I did. I got enough to do my whole trunk and rear deck lid were my 6x9s are by the rear window and had 3 sheets left over. Thinking of getting another box so I can do all 4 of my door but would have a lot left ober after that. So thats still uo in the air but I am going to use whats left from the 1st box on certain rattle poins on the doors for sure. If Youre up in the air about getting this or the more expensive brands just go for it. I know people that have each if the 2 high end brand I for mentioned and Killmat does just as good of a job for about half the price.
