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

It works well

I really like this product, it was super easy to lay out and trim to fit pieces where full sheets wouldnt fit. I could of taken more time and fit it a Bit better but in less than 30 minutes I did the entire floor of a 06 crew cab gmc 2500hd. I have not driven yet for noise test but just tapping on the floor you can instantly tell it will be helpful. My factory mass backing had water damage so I liked this for noise reduction and getting rid of the padding.

My 2016 GMC Yukon XL has over 153K miles and was starting to exhibit a lot of unwanted creaks, rattles, and other unwanted noises. I applied about 10 sheets to the floor pan in the rear cargo area and under the second and third row seats and WOW, what a difference!! It tamed almost all of the rattles and quieted the ride overall. Im going to order another box or two and get to work on my Transit van (350HD,) 2014 Prius, and 2019 Tesla Model 3 next! Absolutely 1000% recommended!!

The best

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.

I went to best buy and got 12SQFT for 100 dollars, then looked on amazon and found 50SQFT for 60 bucks, are you kidding me, this is why brick and mortar stores are going out of business. I didnt have to skimp at all on coverage because i had so much product. It also easily attached where i needed it, but also was able to be shifted around as long as you didnt press it down all the way. I did get a roller set for the professional look. So far I have done all 4 doors of my Jeep Liberty and added 3 sheets to the floor under the driver and passengers feet. AMAZING. it cut down on the road noise and wind noise, also cut out some random vibrations. AND THE SOUND! My stock speakers sound brand new, high highs and low lows. Worth every penny and the hard work to get it in. 10 / 10

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.

Adheres well if you actually do it correctly. I double layered every large hollow hole and it turned out nice and sound. The door no longer shakes at a idle.

This product likely sat in a hot warehouse, and does not work as intentioned. It has an adhesive side, with a covering paper, and then it has a paper that you should be able to peel off the front side of it, but only one sheet out of the entire box worked like that. The rest were all stuck together

I used this in conjunction with egg crate foam material. This inexpensive box went a long way for my Crosstrek project. The car had ridiculous amounts of road noise, could barely hear voices on the stereo. I good roller helps for application. You can cut this stuff to fit anywhere you can reach. I used the egg shell for harder to reach areas. I only applied the mat to metal as it was the sturdiest part of the car. If you ever have to take this stuff off its going to be one hell of a mess. Sticky tar/rubber base but the foil keeps it covered. I also made some non stick pads for the floor mats that work well. While I didnt take measurements with a db meter I did only do my four doors first and kept hearing weird car noises....I didnt do the hatchback. When I did that and added the floor mats my car was as quiet as could be. No ear fatigue from road noise and my stereo sounds great(with some other tweaks). This is subjective but I find that every toyota Ive owned has a pretty quite interior. My Crosstrek is now on the level and maybe a bit better than that. I can listen to the radio at a low volume and still hear.
