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

Decent for what it is…. Not as thick as 80mil I believe but it does the trick. If you do 2 to 3 layers you will be sold just 1 layer might not do it for a big audio build.

Love the thickness for the price . Way cheaper than the top brands,and in my opinion better sound canceling.

Im never 100% sure how well this stuff works, Ive purchased name brand and off brand and never felt like it was a night and day difference, but then again I rarely do a whole car in one go so its more of an incremental change. Does a great job taking buzzing and rattling out of panels for sure, and seems to somewhat improve bass clarity, but I dont know that it does much for road noise etc.

The sound difference is minimal with only a single layer applied. I chose to add a second layer at every point where the base layer met and created a seam. That gives the rigidity I expect. This product does not reduce all sound. It simply adds rigidity to the sheet metal and stops rattles and tinny sounds. Adding a layer of acoustic foam padding under the carpet is still advised if total sound reduction is your goal. As measured with a caliper, the material is just over 2mm thick. 80mil = 2.2mm, so it is as thick as advertised. I still wish it was significantly thicker... It is about half as thick as the old factory stuff I peeled out of my truck. It is worth noting that I am working on a 97 F350 pickup. A modern car has considerably thinner metal and a single layer may work better on modern cars. There is a slight asphalt smell on the material. However, I have yet to notice it once installed. It just smells like fresh pavement out of the box. A handy tip, buy a cheap wooden spatula and use that for the initial fit before using a roller. It is much easier to manipulate into folds and reduce air bubbles. My advice, add an extra box to your order and plan to add a second layer at strategic points to achieve the result you desire. Otherwise, just pay the extra money and get a thicker product. But, for the price, adding a second layer is still probably the best value.

I applied this to the inside of the thin sheet metal on the top and side panels on my Samsung front-load washer and dryer in an effort to quiet them down and eliminate rattling and vibration. It worked amazingly well! Just wish I took pictures while I had it all apart. Also applied it to the bottom and sides of my custom made 14ga stainless steel bathtub of a kitchen sink. It worked fantastic there too. Great stuff!

My truck is just about as noisey as they come, while I wasnt jumping for joy to do the actual job of installing these, ill tell ya - pretty big difference. After the install i remember my first drive thinking whats wrong with my truck? it sounds... weird - what was weird was that it was quiet! Installing these is a labor of love. Find a nice fair weather day, some shade and put on some tunes and just get it done, if your car is noisy this is your solution. It goes on easy and has so far (1 year+) held up great, I have had to remove my door panels to install new mirrors and took a peek inside and its all held up the same as the day I put it on. I ended up doing nearly my whole SUV, interior, firewall, all 4 doors, the back bed/trunk. Made a huge difference, would do it all over again if I had to. 5/5

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.

This was really great quality insulation - stripped my car to the frame (removed trim and chairs etc) and adhered it to the frame itself. Easy to cut the pieces down to size with a simple box cutter (though will get gunked up over time with the black stuff inside). Put it down, kinda use a flat surface thingy (I used an old name tag from work) and then went over it with my hands (the heat from your hands helps). Now my car is clean, quiet and warm in this cold front were all having. Highly recommend if youre looking to quiet your car from outside or engine noises (Id say a good 20-30% decrease from before I did this). Very happy with how it turned out.

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.

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