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

I used a torch to ensure it was sticky because rolling it flat is too much work PLUS I like the pattern! I used it on the floor and on the box and where it is sealed off at the B-pillar, and made a big difference.

I have been in the miserable world of custom cars for over 25 years. i only found a couple honest knowledgeable reviews. I doubt this qualifies as knowledgeable but, I do have some feedback. Does it work? Yes, it does function as sound deadener fairly well. For what you pay this is pretty good. Is it Roadkill or Dynamat ? Nope, that in my opinion is another class of product. I used this on a 77 Toyota land cruiser that has a total budget for upgrades and has a must have list. To cover the same square footage would have been nearly double the money in my preferred brand. I sat down and read the reviews on Amazon and a few other sites. After I hadthe cargo area done I was overall happy with the purchase and continued to finish out the entire vehicle. The first big difference is the adhesion. It is noticeably less than a name brand and requires a bit more surface prep and cleaning to get the maximum sound deadening. That is one of the biggest mistakes you can make with any brand sound deadening product is to not get it stuck to the surface with as few and as small of an air gap as possible. Getting this to stick in all the little cracks without some release takes a bit more work. Is it as dense as a name brand ? Nope again. It is about 80-85% as dense as a name brand . You can hear it after it is applied and feel it when it comes out of the box in weight. The weight is a bonus as it is lighter and i would use it again in a hot rod or go fast project where you were trying to bring down sound while not trying to turn the vehicle into a brick. i did not have a way to compare the heat loss from the application against another brand at the time of this review. I would suspect it to be about the same in that aspect as well in being well sufficient but, not quite as good as a name brand. It does seem like I am hating on the product but, in fact I am not. i would use it again and will for the price. Overall it is a 3.5-4 star product. If value it on price equal to performance it would easily be 5 stars. I gave t the review and rating I did based from use of top tier brands compared to this product. If you are looking for the maximum sound control and heat loss buy a name brand and apply it properly but, have deep pockets. For a budget minded person looking for significant results and still have some money for other parts of your project buy with confidence. I will reiterate This product does take a little more elbow grease to get proper adhesion, buy a good set of rollers and wedges and make sure it is stuck down. No replacement for good prep and proper installation.

Used this to deaden some of the noise in my 2023 Polaris Ranger XP. Easy to use and it deadened some of the sound. I would buy again.

There are other similar products that may (or may not) work better at a greater expense. For my use case, with temperature variations and budget constraints, this was the best option. The only thing I might change would be getting thicker mat, but the sound suppression with this thickness is a dramatic improvement. My old F350 creaks and rattles still, but this sound mat keeps most of the noise from the cab and improves the quality of conversations I hold while driving. I would buy it again, and will, for any future vehicle of mine

8 mil thickness (same as dynamat), super sticky adhesive side, easy to cut and shape. Covered the inside roof of my 56 Chev. I used a short, hard urethane roller and a medium firm long-handled roller to roll it out. Its a bit of work to roll it out over head, but it sure is good when its done. A noticeable difference in cabin temperature and noise. I will be buying more for the floor and doors. Great product and a great price.

I was doing 4 doors and the liftgate, so I only bought 1 box. I didn’t do 100% coverage on the liftgate, but fairly complete single layer coverage on the inside of the door panels (backside of the exterior panel) as well as some of the interior part of the door panel for the 4 doors and had 1/2 a box left over. Used a utility knife and cutting board to cut the material easily. It was a warm FL day so it was easy to roll the material onto the panel with good adhesion. To help cut pieces for odd shapes areas, I put a piece of backing paper in the space and folded or marked it for the right shape like a template. Sound deadening was immediately noticeable, reducing road noise, making the speakers sound much better, and the doors sound more solid when closing them. For even better sound reduction i would suggest pulling the headliner and do the roof too which is thin sheet metal. Maybe I’ll do it in the future. Overall, happy!

I got it for the doors because I put in a new radio. It helped!

Car is noticeably quieter

Excellent product. Easy to install and mold to space. Noticeable reduction in noise. Very pleased with result.

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
