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

Super easy to install! I just cut up the material a bit and applied it with one of the cheap sound deadener rollers that are on Amazon. The noise level went down significantly with only about 30 percent coverage on some of the van panels. Previously, the sound had been so bad, that my husband and I could not hear each other talk even when we were yelling, and I felt like my dental fillings might fall out from the vibrations. After applying the sound deadener, I took a day trip a few states away, and I actually forgot to listen and check on the noise level, because the noise level had reduced so much. I recently replaced a door on my van, and because that door doesnt have sound deadener, you can now hear a lot of rattling but only from that door. Have to get the roller and sound deadener out again.

It’s cut into lots of sheets. It’s easy to install if you lay it in the sun. I don’t have any oil/asphalt smell in the truck. ProjectTwin has great videos on how to install this stuff. I’d recommend watching them and getting MLV sound deadening material to accompany this. It is my next step.

Doing the floors in my 1966 Chevy. POR 15 first then Kilmat. Easy to work with and priced right

I’ll start by mentioning that I’m a professional car audio installer with multiple awards at an international level. I’m not some kid working on his bucket in his parents garage. I first noticed that this material seemed thinner than the claimed 80 mil. So I put a set of digital calipers on it and the mat is closer to 70 mil. Secondly the adhesive backing was less effective than what other products I had worked with the past. But what prompted my return was the fact that unless I applied 3-4 layers the product was ineffective. Check the weight of this product compared to 36 sq ft of a comparable product. You’ll see that Kilmat weighs almost half of what any quality mat weighs. Very misleading. There are plenty of other quality alternatives to Dynamat on the market. Unfortunately this is not one of them…

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!

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.

Its a good product. Am alternative to the dynamat. I only want to write this review because if the way most people use it is wrong. Its not supposed to cover the entirety of the interior panels. You apply this where there are large flat panels or where a piece of metal makes vibrations or resonates. There are more lightweight materials you can use for full coverage but if you add this everywhere its really just dead weight.

My 2nd time using this 80 mil kilmat. First was a 2011 Camry (turned a Toyota into a Lexus. LOL). Put a nice system (Focal speakers, etc) in Camry…. Used the Kilmat inside the doors on the doors skins, under the door panels, trunk floor, trunk sides, trunk lid, license plate, behind and under back seat. It did a great job of isolating the interior from outside…. Knock on the door skins and it sounds like a thud instead of a ring; shut the doors with the music cranked and you barely hear it outside the car! And no rattles from the sub hitting. Now I’m doing a 2011 Tundra crewmax with a very high end system…. Focal utopia components, Focal K2 power components rear, focal flax series subs, Kenwood 1037 head,JL vx800i, JL XD600/1v2,etc Used kilmat inside doors, under door panels, behind rear seat, 4 coats of rubberized undercoating spray under cab, then used 1/4” closed cell foam (siless) over the top of all above listed locations (except outside under cab)… WOW! WHAT A DIFFERENCE! The kilmat isolates and dampens while the closed cell foam adds the acoustic deadening I was looking for. The undercoating sprayed under the cab of the truck added the damping and isolation under the truck without having to pull the seats and carpet to install kilmat.. The sound made from just shutting the doors makes it obvious how much better the listening environment is going to be. I have bought (3) boxes of kilmat 80 mil 36 sq ft, (2) boxes of siless closed cell foam, 3 pack of installation “rollers” …. About 300.00 Spend less on your components and do the above process first. You’ll get much more out of your audio equipment! HIGHLY RECOMMENDED

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.

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.
