Kilmat Car Sound Deadening Mats
Style: 50 mil 25 SqFt
Easy to install in a vehicle! Helps keep the heat out as well as keeping it quieter inside my car. Self sticking to the inside of the roof without strong smelling adhesives. The quality of these pieces work very well in my vehicle!

Excellent Sound Deadening Material!
Style: 10 SqFt, Style: 10 SqFt
I installed Kilmat Sound Deadening in my truck, and I’m extremely impressed with the results. The material is thick, pliable, and easy to cut to fit doors, floor panels. It sticks very well to metal surfaces and doesn’t peel, even after heating it slightly to make it more flexible. After installation, I immediately noticed a reduction in road noise and vibrations. Worth the money!!

A Must Have For Car Restorations!
Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
I have been installing this matting in my 74 Datsun 260Z restore and very pleased with the ease of application and overall quality. My car has bedliner coating inside and this stuff sticks extremely well and is easy to trim and shape as well. I have just started installing it and using the rollers to work it in place but I can already tell a difference with just the little bit I have added....has reduced the resonance in the metal already. It's not a fast process but know it will be very rewarding once complete.

Material Type: 157mil Closed Cell Foam, Style: 157 mil 36 SqFt
The product at least for me worked exactly the way it should have, The adhesion was far better than shown in comments, it was about 45 degrees in my garage it did not budge...I am going to line my subwoofer box next ....
