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

I have a 2013 Mercedes C300 4MATIC. The only place on the vehicle where they do not add sound deadening insulation is in the trunk, where the spare tire lies. I decided to give this a shot because it had a 5 star review. Well, it did not let down! There is a noticeable difference in the road noise. I am very OCD about things, and this took care of all my worries. I utilized the 18sqft package, and had one mat left over. I did a full layer covering the entire spare tire well. It took about 2 hours, with the assistance of my wife. I would highly recommend getting the roller to get air bubbles out and to ensure proper adherence. Prior to installation I cleaned all surfaces with rubbing alcohol and ensured that all particles were swept out. I DID NOT utilize gloves, nor would I suggest it because they just get in the way. I took her for a drive down the interstate immediately following install, and all I can say is. WOW! Definitely worth the $50 bucks. Truthfully, it does not look all that bad, either. All of it is hidden under the spare tire carpet covering, so you have to lift that up before you even know that it is there.Thank you KILMAT!!!!

My girlfriend installed this in the doors of her 2019 corolla hatchback. You can hear a difference before and after by knocking on the outside of the doors. She also said the car is quieter while driving since the install. Less road noise, etc.

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.

The sheets make easy work of applying the material in tight spaces and even cutting pieces to fit odd shapes. I used about 4-5 sheets per door for my Ram 3500 Mega cab. Upon opening the door cavity, there was two tiny sheets of OEM soundproofing on the rear doors and NONE on the front doors. I applied the sheets in as large a piece as possible. I used a heat gun to warm the door and the material. Adhesion is excellent and I used a mini roller to push the material flat onto the door panel. I also used a torpedo level that had a rounded plastic tip to push the material flat in hard to get to places. Id say I covered 99 percent of the door with 4-5 sheets. I also put some of it on each interior door panel around the speaker grill and near the molded armrests. the door panels went from a gong like sounds to a confident dead knock. the door also closes with a definitive thud sound. over all the product is excellent and affordable. I wouldnt hesitate to get another package to place more around the car as I build the system.

Used it to cover up the road noise in my 08 tacoma and it worked amazingly! Wasnt expecting that much of an improvement but it makes a world of difference. Not only that but my music is much nicer now!

Worked great! No smell! Excellent adhesion! Wear gloves! Bu where is it now? I do not see it available anymore. I want to order more but can’t.

Car is noticeably quieter

Bought 2 boxes for a total of 72 sq.ft. Used professional installation service to install the material on all four doors, trunk lid, hood. I installed the remaining material in the trunk myself. Very little change observed on my 2013 Toyota Corolla LE. The installation shop mentioned that the material is too thin, and that they would not recommend it to anyone. For floors and firewall, I decided to use Dynamat Extreme/Hushmat/Soundskins Pro. You get what you pay for. If you really want proper sound deadening, use thicker, highly quality materials. Edit : I installed Soundskins Pro on my floor (including wheel wells) + firewall, and that deadened some of the road noise. Its much more expensive than Kilmat, but it also has acoustic foam in addition to butyl rubber. If you are cost conscious, you could do Kilmat + some closed cell foam insulation like Noico Liner or Siless 157 mil foam (I ordered Siless foam and will be adding it to my doors + trunk + trunk lid to supplement the Kilmat) Edit : Changing from 2 to 4 stars. I recently learnt that just adding butyl layer alone will not get rid of road noise, but will help in dealing with rattles. Most new cars dont rattle noticeably when compared with older trucks/pickups/cars. So, if you install just the butyl layer on the new cars, you probably will be very disappointed even with dynamat/hushmat etc. Adding closed cell foam layer will largely reduce road noise and harshness. I added 15 sq. ft of Siless sound deadening foam to 2 front doors and under hood(also look at Noico liner. If your budget is higher you can get the Second Skins Luxury liner Pro). That alone has dramatically changed how the car feels. I plan to add the foam to the other 2 doors, trunk lid and the trunk sides. I am quite confident that the addition should kill off a lot of road noise for me. A more expensive option, but easier to install option is to go for combination sheets like the SoundSkins Pro that includes both the foam and butyl layer on the same sheet (I got those professionally installed on my floor + firewall)

Got this to reduce trunk vibrations from bass. Wasnt expecting it to cancel it completely. I was surprised with how well it actually did though. After reading reviews of other more expensive products like Dmat and 2ndSkin. But this product also had good reciews as well so bit the bullet to save some cash and glad I did. I got enough to do my whole trunk and rear deck lid were my 6x9s are by the rear window and had 3 sheets left over. Thinking of getting another box so I can do all 4 of my door but would have a lot left ober after that. So thats still uo in the air but I am going to use whats left from the 1st box on certain rattle poins on the doors for sure. If Youre up in the air about getting this or the more expensive brands just go for it. I know people that have each if the 2 high end brand I for mentioned and Killmat does just as good of a job for about half the price.

Easy to use
