KILMAT 80 Mil (2 mm) 36 Sqft (3.4 Sqm) Car Sound Deadening Mat, Alubutyl Automotive Sound Deadener, Audio Noise Insulation and Dampening

This is a good product. Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product.

A good sound deadener. Very easy to apply and easy to cut. Recommend for anyone who needs to quiet the interior of their classic car.

This polyurethane soundproofing material effectively reduced noise levels in my car, creating a much more pleasant driving experience. Installation was straightforward, and the mat easily conformed to the contours of my vehicle. The build quality is impressive, and it significantly dampened audio noise and vibrations, making my music sound clearer than ever. Moreover, the mats help maintain a comfortable temperature inside the car, even on hot days. I highly recommend KILMAT for anyone looking to enhance their vehicle's interior comfort and sound quality. This product truly exceeded my expectations!

Use this on my 2026 Tesla model Y juniper for sound deadening inside the doors when I had them apart to install self presenting door handles and soft close door latches. There is essentially no sound deadening in the door other than a pathetic little piece of sticky foam right in the middle of the large expanse of sheet metal on the inner door as it comes from the factory. Despite them upgrading the new model Y with acoustic glass, I feel that internal door sound deadening such as this, is mandatory to prevent "tin canning". It seems to subjectively make a huge difference as my wife states that it is probably 80% less noisy in the car since I did this to all four doors. Highly recommend this as it is both effective and economical.

I’ve bought this product twice now and it works as advertised I enjoyed his cheap price point and it’s effectiveness. Not five stars just because I’m a little worried about the smell but last time I installed it did not so I’m pretty confident

I bought these to help sound proof my network rack. They do an amazing job. So easy to install and the glue is really strong. You can cut them down to fit. I also put some in my Nas to help with vibration from the hdd. Excellent price.

Great stuff. Use this in conjunction with the foam. My truck sounds like a luxury car. Buy more than you think you will need. It goes very fast. I have ordered several times and I still need more. It’s ok to cut. Use a razor blade to make it easier. Sticks very well. Overall I’m happy to have used this. The sound in the truck is very quiet. It’s a newer truck but they aren’t made the same as they used to be. Another benefit, the speakers are more clear too. Great purchase!

Easy to apply, sticks well, and makes panels feel more solid. I noticed less vibration and a quieter cabin after installation. A good choice if you want a practical upgrade without much hassle.
