KILMAT 80 mil 36 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

Before purchasing, I researched several manufacturers of Sound Deadening material. I drive a truck with off-road tires and enjoy quality sound from my radio without road noise interference. All of the leading manufacturers of sound deadening material use butyl rubber in various thicknesses. I bought the .80 ml thickness from Kilmat because of the positive reviews and the price. I installed the Kilmat material in all four doors and on the back firewall. While I don’t have a decibel meter to provide firm data, the decrease in road and tire noise after installation was noticeable and, in fact, I would say surprising and significant. I definitely enjoy driving on the highway more in a quiet vehicle. My guess is that it decreased road noise level by 30% or perhaps more. The key is to buy enough material to line the “inside” metal skin of your “outer” door as shown in the photos. In summary, the purchase was well worth the effort and cost.

I installed this in my 1969 Camaro to reduce the noise level while driving. I had already installed new carpet and insulation but it was still loud inside the car while driving. I removed everything and installed the Kilmat on the floor, inside the door panels, and inside the quarter panels. It truly made a huge difference and made me a believer in this product.

I love this product

I bought these for my noisy 79 Trans Am and they are great! Easy to apply and easy to cut. Drastically improved the noise level inside my car. Would definitely recommend.

Excellent product. Easy to install and mold to space. Noticeable reduction in noise. Very pleased with result.

Worked great! No smell! Excellent adhesion! Wear gloves! Bu where is it now? I do not see it available anymore. I want to order more but can’t.

This product is easy to use. Extremely sticky, great adhesion. The bumpy pattern realy helps to let you know where youve rolled it out.

Installed in all four doors of my double cab Toyota Tacoma. I covered as much surface area as I could reasonably reach, so probably 70% of the entire door since there are side impact bars, body lines, window mechanisms, etc. inside the door. I like very much that the back foil has bumps to make it easy to tell when it’s properly rolled down or not. In my case, I installed in the Texas summer so adhesion and flexibility were no issue. I also like that it didn’t leave black goo on my fingers as another brand did. The adhesive seems to be really good, too. The biggest (only?) challenge was getting it rolled into place because there’s not much room inside the doors. My hands were all banged up and bloody from sharp edges and screws and whatever all is hiding in there, but that’s not the mat’s fault. Once all was reassembled I went for a drive. All the way from idle up to 75mph there’s a definite reduction in road, tire and engine noise. It’s not magically silent, but you hear music better and can speak more easily with one another. I’m convinced enough that Im going to sweat my ears off to put this on the back wall of the cab and then put it into my other vehicle as well.

Worked pretty well for quieting my car down. It’s easy to cut to size and to apply, and I didn’t notice any smell. Id say I went for about 60% coverage and ended up using about 1.5 of the 3 boxes I ordered.

I drive a Ford Excursion and the first project was the four doors, second was the barn doors, third was above the headliner, and finally the rear quarter panels and under the cargo area carpet. Each step yielded an improvement and now that its all done I have to say the interior is so much quieter and the truck feels more solid. Of course it is! Another advantage is the truck doesnt get as hot since the Kilmat is a good insulator even though its inside and the sun still beats on the painted steel body. The a/c cools the inside much faster and more effectively. The next thing is to coat the roof with Line-X and there is sure to be a huge temperature improvement. Great product at the right price. If you want to spend the extra for the D brand, think twice before you buy. Calculate the material weight per sq ft and compare!
