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

I completely covered the floor and cargo area of my c5 corvette. It cuts way down on road noise a fiberglass car will produce. Virtually eliminated rattles and vibration. Greatly reduced the amount of heat from the torque tube in drivers compartment. Definitely improved the sound of the Bose system especially the sub

Absolutely awesome. I used these in my 67 Camaro (350 cid with stock dual exhaust manifolds and exhaust system). Very easy to install (place mat down for fitting), applies easily (use a roller), sticks very well. The noise reduction is incredible. You can hear the engine, but significant reduction in road and exhaust noise. Conversation volume is at normal level. My buddy made a phone call and was able to speak at normal levels and no issues hearing conversation. It’s like riding in a new car. Very happy with purchase. Great product and great price compared to other sound deadening materials.

Good adhesive works better than I expected

You get a lot for what you pay for. Noise is cut down by at least 60%. Highly recommended. Nice product. Will definitely use again.

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.

2001 GMC Yukon XL is like a big noise tube. I had an aftermarket exhaust installed and at certain engine rpms the harmonics that went through the exhaust was amplified inside of the vehicle so much that it was almost painful to the ears. And if anyone was sitting in the third row seating, forget about talking to them. I was skeptical about how well this would work but, on a whim, I decided to try this, as I was pulling the seats and carpet to clean them anyway. There is a 5 piece rolling tool installation kit that is also available, but I dint purchase it and had no problem with installation. In fact, I found that by wearing a pair of mechanics gloves (fabric, NOT NITRLE OR LATEX) it made it easy to really push the matting into small crevasses and around curves. I did have a laminate roller that is about 4 wide, and I did use that on some larger areas, but found myself defaulting to using the gloves instead. No doubt the rolling tools would have helped but I dont think you need them to have a successful installation. On the instructions, it says that you should roll out the matting until all of the waffle pattern is gone; but I pushed and rolled and pushed and rolled and was almost never able to completely eliminate the waffle. At the end of the day though, I feel like I got it installed successfuly. The mat is easy to cut with scissors or a utility knife. The backing is very sticky and once its down, dont even think of trying to pull it up. (NOTE: the day I installed it, it was in the low 90s so Im sure that helped with the adhesion). After installing, I took the vehicle for a test drive and was shocked how much quieter the vehicle was. It is still a little noisy, but soooo much better. At least now I can talk to someone sitting in the third row, while driving. I only have two regrets. 1) I should have bought another box. The 50 sq/ft box I got only covered around 85% of the floor. 2) I should have bought the 80mil matting instead of the 50mil as Im sure that would have made an even bigger difference.

Ive used other products before - Dynamat, second skin, etc. They worked well, but were $$. This product is cheaper, perhaps just slightly less thick - though, not by much. It also sticks well and seems to quiet things down quiet a bit. Frankly, you can almost double it up and stay under the price of the other leading brands. I would suggest wearing gloves. The adhesive doesnt come off, but the material will slice your hands up - like paper cuts. Not a lot of fun. Aside from that minor gripe, the product really is a great value!

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.

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

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