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

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.

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.

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…

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.

I applied this to the inside of the thin sheet metal on the top and side panels on my Samsung front-load washer and dryer in an effort to quiet them down and eliminate rattling and vibration. It worked amazingly well! Just wish I took pictures while I had it all apart. Also applied it to the bottom and sides of my custom made 14ga stainless steel bathtub of a kitchen sink. It worked fantastic there too. Great stuff!

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

I bought this to quiet my Mercedes Sprinter cargo van. it cam with NO sound deadening , just a tiny ineffective mat inside the hood and engine area. Wow this stuff is really easy to use, just cut with scissors peel and stick. it sticks very well it is a warm day. my van was so loud that we could not carry on a normal conversation before adding the killmat , now it is easy. cost is very effective at less then 10 bucks per door for example. 20 buck for my huge ceiling above the driver and passenger in front. now I have zero road noise and want to cut down the diesel engine noise .. going to but more for the firewall and floorboard areas to cut down the engine noise, but that is just a nice to have at this point. Kilmat killed my noise problem

I got it for the doors because I put in a new radio. It helped!

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.

I used this on my wheel wells and part of my roof. I couldnt be happier with those product. It made a tremendous difference in road noise. There is a rubber or tar smell when you first put in on but it dissipates after a day or so. I left the doors open to let it air
