KILMAT 50 mil 50 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

It removed almost all of the resonances inside my TrailBlazer SS and quieted the ride overall. I did use two boxes to get everything, including the inside of the car roof and inside wheel wells and door banels. Lining the overhead made a huge difference, I definitely recommend doing this. My AC seems to work so much better now and the car just does not get as hot inside, at least not anywhere near as bad as it used to when left sitting in the sun all day.

Great stuff. Easy to apply and was able to cut easily. Be careful when applying with your hands. I forgot how sharp the foil can get and sliced my finger.

It works well

Ive used other products before - Dynamat, second skin, etc. They worked well, but were $$. This product is cheaper, perhaps just slightly less thick - though, not by much. It also sticks well and seems to quiet things down quiet a bit. Frankly, you can almost double it up and stay under the price of the other leading brands. I would suggest wearing gloves. The adhesive doesnt come off, but the material will slice your hands up - like paper cuts. Not a lot of fun. Aside from that minor gripe, the product really is a great value!

I was skeptical about the sound deadning quality, but after i installed it i realized it work. You gotta cover the complete floor and rear wall of a single cab silverado, for it to be effective . Dont try and cut corners, remove everything and clean everything well so it will adhere to what ever your applying it too.

Replacement for 1968 Tornado under carpet. Good adhesive and coverage. Can’t address sound blocking as car is yet to be on the road due to rebuild.

I bought the 50 square foot package and it came in just the right sizes that made it and easy job to piece them together and get great coverage. This is the floor of a 1976 F150. These sheet metal floors are usually quite tinny and transmit road noise. With only a couple of sheets installed I could already tell it was working and it looks great too! I bought a package of three sizes of rollers to facilitate the install.

The road noise and overall tinny sound of closing the doors, trunk, etc. on a 2008 Accord Coupe got me to searching for a solution. Installed this stuff everywhere - on the floor, inside the doors, inside the trunk, on the ceiling, and on the rear-fenders (from inside; theres an opening under the trim). We also added Noico adhesive foam to further control road noise. It made a huge difference and the car is much more pleasant to drive on the highway now. Also, closing the doors now makes a reassuring, solid thump. Note: Handling the headliner to remove it killed the foam under the cloth. :-( 11 years of baking under a black roof, in the Texas sun, had weakened the foam. It crumbled from the handling and the liner started to sag in just a couple of days. Ugh! Pulled out the headliner and had it recovered at a local shop. Had I known this was a possibility, I might have left the ceiling alone! That ended up costing an extra $125 ($250 if the shop also did the remove and install of the headliner).

I have never used sound deadening mats, but I customize my cars A LOT. The price of this product is way lower than the leading brands but the quality is fantastic. I thought I would be getting a lower quality alternative- side by side it looks and feels like the big name brands. You will notice how heavy the stuff is from the box, which wasnt light nor fluffy. I especially liked the grid system for easy and precise cutting on the foil side. Once I measured and cut, install was a breeze. In fact, I had to re position a few pieces, the glue had no problem adhering even with a couple of times off and on. I did the door panels on my Tesla, which was already pretty quiet. It seems quieter but unfortunately that is seat of the pants, not scientific. I didnt take before and after readings. I did put some behind the speaker in my Ram truck and sound DEFINITELY comes out louder than before, with less loss behind the speaker. 50 square feet is more than enough to do a vehicle completely. The instructions recommend using gloves- I didnt and found no ill effects or reduced adhesion.

Have used these on multiple vehicles and am very happy with the quality and price point. They stick very well! I recommend getting a set of rollers to really put some pressure when installing. I lined my trunk/hatch area in my 07 Honda Fit and noticed it was quieter (even with the wind noise Fits are know for:) I follow it up with some sound deadening mat. Very happy with this product! Would and have bought again!
