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

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.

Before purchasing, I researched several manufacturers of Sound Deadening material. I drive a truck with off-road tires and enjoy quality sound from my radio without road noise interference. All of the leading manufacturers of sound deadening material use butyl rubber in various thicknesses. I bought the .80 ml thickness from Kilmat because of the positive reviews and the price. I installed the Kilmat material in all four doors and on the back firewall. While I don’t have a decibel meter to provide firm data, the decrease in road and tire noise after installation was noticeable and, in fact, I would say surprising and significant. I definitely enjoy driving on the highway more in a quiet vehicle. My guess is that it decreased road noise level by 30% or perhaps more. The key is to buy enough material to line the “inside” metal skin of your “outer” door as shown in the photos. In summary, the purchase was well worth the effort and cost.

Car is noticeably quieter

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 am in the midst of upgrading the audio system in my (new to me) 2009 Acura RDX. Six of the ten factory installed speakers had seen better days. The voice coils were shot in several of them found in the driver and passenger, front and back doors. There is a lot of great information available on you tube videos on steps to take to improve the sound quality of your auto sound system. Of course, replacing the speakers with some quality aftermarket models is an obvious first choice. I learned that another item to consider is Kilmat Car Sound Deadening Mat, available in 80mil and 50mil thickness. The thicker the better is good to consider installing when possible. Cut out paper templates of the various shapes and sizes of the mat for good fitment. Disposable surgical trauma scissors do a good job of cutting the mat to desired size. Be sure to also purchase the 3-pack of installation rollers. It is important to roll over the mat with the rollers to ensure proper adhesion of the sound deadening sheets to the metal door panels. Kilmats waffled aluminum top sheep product design easy shows where the mats have been rolled. The installed mats do add some weight to the vehicle. However, the marked decrease in sound reasonance is a welcome trade-off. Even installing mat to ~25% of the door panel will result in considerable sound deadening.

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.

Had no issues. Has been as advertised, applied but yet to road test for sound.

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.

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…

8 mil thickness (same as dynamat), super sticky adhesive side, easy to cut and shape. Covered the inside roof of my 56 Chev. I used a short, hard urethane roller and a medium firm long-handled roller to roll it out. Its a bit of work to roll it out over head, but it sure is good when its done. A noticeable difference in cabin temperature and noise. I will be buying more for the floor and doors. Great product and a great price.
