5.0 out of 5 stars Affordable Alternative to Dynamat ad a Fraction of the Cost
By T. McFarland on March 5, 2018
I almost went the "poor mans" way and bought Frost King Foam Duct Insulation, but then I saw this Kilmat sound deadening was about the same price as the Duct Insulation. Using prime, I ordered and received the package the same day. I found it was easier to work with this material with my bare hands as using gloves the adhesive stuck to the gloves making it difficult to install - once I took the gloves off it was much easier to work with the material. I also found it to be easier to use a good pair of scissors instead of a straight edge razor - the material is thin enough to use scissors. It was a cold day outside and when the temp dropped below about 42 degrees the kilmat material became much harder, so recommend installing on a day between 50-70 degrees outside. Also, the foil liner wasn't too sharp, I didn't have to worry too much about cutting myself using my bare hands.

As far as it doing it's job as a sound deadening material? I installed these in a 2018 Jeep Grand Cherokee, and I can definitely tell a difference on the road noise, especially on the highway. It's probably a good 25% quieter, if not more. My doors feel heaver, have a nice THUNK when I shut them, and sound solid when I tap the doors with my knuckles. I replaced my speakers in my doors at the same time and I am very happy with the results - no rattles and great sound. I did two layers - one on the outside panel and one on the inside panel - maybe overkill, but I received 50 square feet, which was enough to do all four of my doors doing double layers. This is A+ material.

5.0 out of 5 stars Extremely easy to install with a couple of simple tools
By Dan N. on December 14, 2018
I purchased this to line the bed of a project vehicle...my 1991 Bronco. With a hard wallpaper roller and a pair of decent, not great, shop scissors and a rubber mallet...yes, a mallet. Started with the fender wells, curved surfaces take a little thought, though even an overlap can easily be rolled flat. Made the seams near perfect by tapping them down with the mallet. Flat surfaces were a snap. The bed/floor is not flat, so I rolled the indentations "sideways" to work the material down. Went in way easier than I anticipated. Sound attenuation is "pretty good" for about 3/32 +/- thickness. I'd like to have had larger pieces, although they may have been a PITA to install, the sticky is pretty sticky...but does allow re-positioning. On a difficulty scale 1-5, 5 being hardest, I give it a 2.

5.0 out of 5 stars Good deadener get it while it's cheap
By Raheen T Frasier on October 15, 2017
Awesome I'm running 5k on 1 NSV3-15 tuned low and she is holding up very well some are double layer but 50sqft for $60 is a hella deal especially for butyl. Can't beat it. Amazon have the lowest price right now , stop contemplating and buy it you won't be disappointed.

5.0 out of 5 stars Awesome stuff, just as advertised.
Reviewed in Canada on March 28, 2018
This product is as good or better than the industry standard “mat”. It comes packaged in sheets and is easy to apply. Make sure to get a roller tool so that you can apply the correct pressure to apply the kilmat. I bought the 50 sq ft package, which was enough to cover the entire floor of my GMC Canyon and still had enough left over for the rear wall and at least two doors.

Haven’t had a chance to get the truck on the road, but it made a noticeable difference in both the echo’s in the cab, and the sound coming off the sheet metal.

Overall a great product and would recommend to anyone looking to make their car quieter.

5.0 out of 5 stars Phenomenal product! ** Edit **
Reviewed in Canada on May 25, 2018
This stuff works very very well. I have an old (1995) regular cab truck and this stuff made my slim 12 go from sounding like a 6x9 to a proper 12" sub. Road noise was greatly reduced too. It was incredibly easy to use, first time I had used anything like it. I did both of my doors, the whole back portion of my cab and I still have over 10 sheets left.

*Edit*
I used the remainder to improve the sound quality in my girlfriend's hatch back car. I couldn't do a perfect job but remember that's what I had left over from already doing my truck. So what I have pictured is what I was able to cover with the single box. I'm impressed in every single aspect of this product!

5.0 out of 5 stars Works well, way cheaper than the brand name stuff
Reviewed in Canada on June 21, 2020
Lined the floor, trunk, outer door skin and inner door skin each with one layer. Interior road noise was significantly reduced, sound quality from the speakers was, noticeably improved, and much more solid feeling closing the doors making the car feel far less like a tin can. Took 2 50sqft boxes to completely line my Mazda protege. Would probably be an even bigger improvement had I used 80mil stuff but even with 50 the difference is already night and day.
