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

If you have ever had a rattle trap fbody, you understand that the road noise is horrific, and theres alot of squeaks . In an effort to make the car more enjoyable on a highway drive, I figured Id try it out. I got way more product than I had figured I would get so thats a plus. The key is to hit the main areas of noise, not every single square inch. Thats just added weight with no real benefit. It did help the road noise a good bit and I still have like 6 sheets left to install in my trunk pan. I took the car on a 1600 mile trip shortly after and enjoyed it so much. Buy the $10 rolly tool they recommend, its very worth it, and wear gloves. That foil is sharp! Ill be ordering some more in the future for my door skins and up in the headliner area.

I applied this to the roof on the inside of my car. It went on easily and stuck very well with little effort. I liked the pattern in the foil that helps you see how well you have rolled it. This was also priced well - a great value.

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.

My truck is just about as noisey as they come, while I wasnt jumping for joy to do the actual job of installing these, ill tell ya - pretty big difference. After the install i remember my first drive thinking whats wrong with my truck? it sounds... weird - what was weird was that it was quiet! Installing these is a labor of love. Find a nice fair weather day, some shade and put on some tunes and just get it done, if your car is noisy this is your solution. It goes on easy and has so far (1 year+) held up great, I have had to remove my door panels to install new mirrors and took a peek inside and its all held up the same as the day I put it on. I ended up doing nearly my whole SUV, interior, firewall, all 4 doors, the back bed/trunk. Made a huge difference, would do it all over again if I had to. 5/5

I used this on the rear deck of a 2019 acura tlx with a kicker 8 inch sub driven by 200 watts rms. The metal was flexing very badly and the noise from vibration was horrendous. One layer of killmat completely silenced it.

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.

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 have used several products like this. being on a budget for the latest project this was the way to go. It works well and was easy to install.

It does work good but doesn’t cancel as much noise as I expected. In my Polaris Northstar it helped a good bit on noise canceling but still a bit louder than I wanted. Where the Kilmat knocks a home run is vibration from the subwoofer and sound system.

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.
