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

1995 jeep yj, covered the entire floor front to back, covered rear finder wells. I did not leave any uncovered areas. covered with a new carpet kit. I honestly cant tell one bit of difference, sometimes it actually seems louder. adding jute padding over it next to see if that helps.

I have been in the miserable world of custom cars for over 25 years. i only found a couple honest knowledgeable reviews. I doubt this qualifies as knowledgeable but, I do have some feedback. Does it work? Yes, it does function as sound deadener fairly well. For what you pay this is pretty good. Is it Roadkill or Dynamat ? Nope, that in my opinion is another class of product. I used this on a 77 Toyota land cruiser that has a total budget for upgrades and has a must have list. To cover the same square footage would have been nearly double the money in my preferred brand. I sat down and read the reviews on Amazon and a few other sites. After I hadthe cargo area done I was overall happy with the purchase and continued to finish out the entire vehicle. The first big difference is the adhesion. It is noticeably less than a name brand and requires a bit more surface prep and cleaning to get the maximum sound deadening. That is one of the biggest mistakes you can make with any brand sound deadening product is to not get it stuck to the surface with as few and as small of an air gap as possible. Getting this to stick in all the little cracks without some release takes a bit more work. Is it as dense as a name brand ? Nope again. It is about 80-85% as dense as a name brand . You can hear it after it is applied and feel it when it comes out of the box in weight. The weight is a bonus as it is lighter and i would use it again in a hot rod or go fast project where you were trying to bring down sound while not trying to turn the vehicle into a brick. i did not have a way to compare the heat loss from the application against another brand at the time of this review. I would suspect it to be about the same in that aspect as well in being well sufficient but, not quite as good as a name brand. It does seem like I am hating on the product but, in fact I am not. i would use it again and will for the price. Overall it is a 3.5-4 star product. If value it on price equal to performance it would easily be 5 stars. I gave t the review and rating I did based from use of top tier brands compared to this product. If you are looking for the maximum sound control and heat loss buy a name brand and apply it properly but, have deep pockets. For a budget minded person looking for significant results and still have some money for other parts of your project buy with confidence. I will reiterate This product does take a little more elbow grease to get proper adhesion, buy a good set of rollers and wedges and make sure it is stuck down. No replacement for good prep and proper installation.

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.

Works great if installed properly. USE A ROLLER

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

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

Decent for what it is…. Not as thick as 80mil I believe but it does the trick. If you do 2 to 3 layers you will be sold just 1 layer might not do it for a big audio build.

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.

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.
