OK, first of all I've been professionally taking cars apart and putting them back together for the last 7 years as an autobody/refinish tech. You see some cars with little to no sound deadner and some higher end cars with lots of it. Eventually you come to see/hear/feel the difference this stuff actually makes for cars that didn't have it at all or have very much of it. We've always used the 3M sound deadner pads that are shiny, black, and come 10 large (19"x19") squares in a box. Did a 2008 Crown Vic with those, they worked well. Those are much thicker than this stuff and weigh a fair amount more. (NO, I'm not complaining about weight) I just always thought that if it was heavier it HAD to be better. Well, I'm working at a different larger shop now, and it would've been harder/more expensive to get the 3M pads, so I gave these a shot. I had to do a 2011 Hyundai Santa Fe for noisy/hollow sounding doors, a couple of which pinged like a drum head when they closed, thanks to the foam/adhesive breaking down on the diagonal support inside the door that the door-skin is bonded to. So, I did a few big strips, (it does not need to be completely covered!!) inside all 4 passenger doors, and rear gate. The stuff cuts good with a sharp box-cutter (watch the foil edges) Also, it sticks very well when pressed or rolled into place. I then added some Noico red foam to help with additional road noise dampening and insulation. I know some people complain about the "smell" but I never noticed it at all in the Hyundai or my 2018 F-150. This stuff worked great! got rid of all of the pinging/hollow sounding doors and it also gives you a pleasant increase in sound quality/bass response even with stock speakers! The Hyundai doors now sound like closing the doors on a car 3x its price tag with by doing that. They sound nice and solid now when they close. I also did all the doors on my 2018 F-150 with the other half of the box of this and the Noico foam, good results there too!! I will still have a small amount leftover that will go somewhere in the F-150 cab. Good price! Definitely recommend to get rid of hollow/cheap sounding doors or added for those looking for better sound!

I installed this in a customer's 2018 Dodge Durango RT. He installed a loud muffler system and had bad drone inside the vehicle. I installed it on the floor of the rear cargo area and on the rear hatch. After installing this product it made a considerable difference inside! My customer was very happy with the difference. I was impressed and I would highly recommend it if you need sound deadening for your vehicle.

I am a big believer in buying once and crying once on certain things. I've been using Kilmat for years in my cars and happy to pay more for a product that I know will deliver the expected results every time. It is easy to cut, apply. I use it inside of doors, trunks, and underneath the carpet. It makes a significant difference in quieting the car as well as reduction in heat transfer from the engine and exhaust.

Installed this in my Porsche Cayman S to help put a sound barrier between me in the engine. Worked perfectly. Super easy to install and overall just a good quality product.

Also, used it underneath my pool pump motor (they get noisy and the vibration travels) and it helped with that as well. Gave 2 sheets to my neighbor and he was happy with it as well with his pool pump.

this mat is very good and much less expensive, used it on my 4 truck doors and could tell the sound difference right away !!!!! road noise is much less and the sound in the cab is very quiet !!! would recommend this product for sure.
