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

Being the first time I have used this I didnt know what to expect. Was it going to be hard to install? Would I hear a sound improvement? I was watching videos of people installing it and they said to let it heat up in the sun. There is a point when it gets a bit to hot and it flops around and is super sticky. I was putting this in the door panels of a 2019 Honda Civic 2dr. Not a lot of room to work with and it wants to stick to every little thing it touches. Not a bad thing but just takes more care to get it in there. I did the bottom 2/3 of the doors. Now when you tap on the doors its just a thud. Overall sound from the stereo was improved. The low notes are now MUCH cleaner! The bass guitar sounds like a bass guitar and not just some humming low note. Same goes for the bass drum. Much more defined and musical. I cant say anything about noise reduction from outside the car yet because I just havent driven the car enough. So for under $50 its worth it in my opinion.

I am in the midst of upgrading the audio system in my (new to me) 2009 Acura RDX. Six of the ten factory installed speakers had seen better days. The voice coils were shot in several of them found in the driver and passenger, front and back doors. There is a lot of great information available on you tube videos on steps to take to improve the sound quality of your auto sound system. Of course, replacing the speakers with some quality aftermarket models is an obvious first choice. I learned that another item to consider is Kilmat Car Sound Deadening Mat, available in 80mil and 50mil thickness. The thicker the better is good to consider installing when possible. Cut out paper templates of the various shapes and sizes of the mat for good fitment. Disposable surgical trauma scissors do a good job of cutting the mat to desired size. Be sure to also purchase the 3-pack of installation rollers. It is important to roll over the mat with the rollers to ensure proper adhesion of the sound deadening sheets to the metal door panels. Kilmats waffled aluminum top sheep product design easy shows where the mats have been rolled. The installed mats do add some weight to the vehicle. However, the marked decrease in sound reasonance is a welcome trade-off. Even installing mat to ~25% of the door panel will result in considerable sound deadening.

I used this on the rear deck of a 2019 acura tlx with a kicker 8 inch sub driven by 200 watts rms. The metal was flexing very badly and the noise from vibration was horrendous. One layer of killmat completely silenced it.

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

Used these to settle down the vibration on my hood, trunk lid, etc. after I changed my OEM engine mounts to less squishy custom mounts. Highly recommend.

First time using this and was very pleased. I made sure to degrease the floor and make sure floor was dry. I liked how the sheets were in manageable sizes and this was so easy to cut when I needed to trim off pieces. I didn’t cover every inch of the floor and figured even if there are small gaps it would be better than before. Very easy to use. One box completely covered the floor of my crew cab.

Awesome product. Installs very easy. Really made my cab quieter in my 99 7.3 Powerstroke. Tech tip leave it inside somewhere cool until install because it gets very mushy and messy when warm.

We ended up buying 6 boxes total of this and used on the inside of a Tahoe that is being restored

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.

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)
