Bests & Worsts Reviews from Amazon

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.
