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

Accurate and fast delivery

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.

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 completed a full replacement of the interior of my 86 K20. Once I had everything out of the cab, I cleaned the painted floor and put these squares down. I did not get meticulous and cover every single square inch of the cab floor but definitely got 99% of it just to the back wall of the cab. This box was more than enough and I still have about 1/3 or more of the box left. I went from a rubber mat to new carpet on top of this stuff and there is a noticeable difference in the sound level. Hard to say how much is from this and how much is from the carpet itself but the interior is much more comfortable now.

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.

The price is right and its easy to apply once youve gained access to the place you want to install. Cuts easily with house hold scissors. The more you apply to a panel the better it works. You need at least 25% of the open panel to be effective. My goal was a minimum of 60% and it worked nicely and finished with some close cell foam in the rest of the panel. I did 100% of my spare tire well in the trunk. Now I hardly hear anything from the area. It can be a little addictive once youve discovered how and where it works best. I plan to do the entire floor (2nd greatest source of noise intrusion into the car) and then the roof panel (pain in the arse) to close out the project. Total cost estimate will be just over $350 to complete a 2012 Toyota Camry LE Hybrid. Keep in mind I require a lot more material for this car as it has the very minimum installed to reduce weight. Ill be introducing 85 lbs of material and a full size space and tool kit (additional 20 lbs) to this hybrid vehicle and it will effect the mpg. The car is usually empty during daily 80 mile city/highway commuting and averages approximately 38 mpg with the eco turned mode off.

The sound difference is minimal with only a single layer applied. I chose to add a second layer at every point where the base layer met and created a seam. That gives the rigidity I expect. This product does not reduce all sound. It simply adds rigidity to the sheet metal and stops rattles and tinny sounds. Adding a layer of acoustic foam padding under the carpet is still advised if total sound reduction is your goal. As measured with a caliper, the material is just over 2mm thick. 80mil = 2.2mm, so it is as thick as advertised. I still wish it was significantly thicker... It is about half as thick as the old factory stuff I peeled out of my truck. It is worth noting that I am working on a 97 F350 pickup. A modern car has considerably thinner metal and a single layer may work better on modern cars. There is a slight asphalt smell on the material. However, I have yet to notice it once installed. It just smells like fresh pavement out of the box. A handy tip, buy a cheap wooden spatula and use that for the initial fit before using a roller. It is much easier to manipulate into folds and reduce air bubbles. My advice, add an extra box to your order and plan to add a second layer at strategic points to achieve the result you desire. Otherwise, just pay the extra money and get a thicker product. But, for the price, adding a second layer is still probably the best value.

Easy to apply and I will recommend it to anyone it does the job and no more rattle thank you kilmat mp

I drive a Ford Excursion and the first project was the four doors, second was the barn doors, third was above the headliner, and finally the rear quarter panels and under the cargo area carpet. Each step yielded an improvement and now that its all done I have to say the interior is so much quieter and the truck feels more solid. Of course it is! Another advantage is the truck doesnt get as hot since the Kilmat is a good insulator even though its inside and the sun still beats on the painted steel body. The a/c cools the inside much faster and more effectively. The next thing is to coat the roof with Line-X and there is sure to be a huge temperature improvement. Great product at the right price. If you want to spend the extra for the D brand, think twice before you buy. Calculate the material weight per sq ft and compare!

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.
