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

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.

Work just as advertised and will definitely recommend 2 boxes and still need one more to finish my floor to have the whole truck done

Best bang for your buck. At a fraction of the cost of name-brand sound mat, this is absolutely unbeatable. I appplied liberal coverage (~80%) in my daily driven Nissan Juke, and the difference is definitely noticeable. Drastic improvement in sound quality inside, and a pretty significant reduction in noise heard outside. I also applied some matting to the floorboards, door, and roof skins on my G35 which really only sees track days. I’ve had it in my G35 for several years now, and have seen no signs of decreasing adhesion. Bottom line: don’t spend more for a product that isn’t really all that much better, when you can have a comparable alternative at a fraction of the cost.

Great product! Like the results

Works well, within its limitations. Its not going to turn your 90s tin can car into a modern lexus, but it was a pleasant change in my 2012 Miata, making everything sound more solid, the stereo sounds better, and marginally less road noise. Make sure to get the application roller tool, as its essential for proper application. One note, you dont need to entirely cover panels. One sheet or a large square on a panel will work 90% as well as covering the whole panel. The purpose of this is to dampen vibrations. It is not sound deadening mat, despite being labeled as such. For proper sound deadening you need something to isolate the sound. This is usually closed cell foam, or something like carpet padding.

This stuff worked as good as or even better than the stuff costing 5x this amount..

Seems like it works. Did not check with a meter before or after but I feel as if the difference is somewhat minimal. I decided to buy and install this stuff on a Class C RV cab because of the intense amount of road noise. I realize that an RV is a moving house on wheels and will make all kinds of noise, but I really couldnt have a conversation with my wife when driving without yelling or hear the radio. I found killmat and decided to tear everything out and install these mats on doors and floors. I already had heat/sound resistant material in the doghouse from a previous install and do NOT recommend using this stuff in that heat. Post install drive seems like it reduced noise about 15 to 20 percent. Enough to have a conversation without yelling. My wife and kids say that they can tell the difference but Im a little more critical of my work. I also swapped out the crappy ford speakers with better speakers and can hear the radio fairly clearly. The difference is NOT night and day...it is more like night and early morning. It works but this is still an RV. It may work better in a regular vehicle. Was it worth all of my sweat to install...yeah, I think so.

Excellent product I would buy it again

I prefer this to thicker offerings because it allows for flexibility. I can double up layers in more resonant spots and do single layers in spots that don’t need much help, or where I just want heat isolation. This product is not a noise isolation product, it is a damping material for panel resonance. It will do a little but if you are looking to substantially lower road noise level, this is not the product to use. With that said, it is the best damping material per sqft and price on the market.

I used all but 2 sheets. It forms well and sticks like crazy!
