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

EXCELLENT PRODUCT AND NO SMELL AT ALL.

there is a asfalt smell in it, is it a butyl rubber or asfalt? i seal it with alimunium tape to stop the smell, and always i keep windows open , about noise concellation, i do the four doors, i didnot see any difference until now, the product is easy to cut, the adhesion is good, but i cant juge adhesion now. it need some time. the product is from russian federation, the manufacturer says that for thickness 80 mil ,the weight is 2.44 Kg/m², the weight of the small sheet 15.7inch x 9.8 inch =0.1 m² is 0.224kg => so the product that i receive is 2.24 kg/m² 200g less.

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 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.

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

Did all 4 doors of my 2020 Taco and had 7 pieces left over out of a 36 ft box. This stuff works great. I didnt realize how much noise I was listening to until I wasnt. Very easy to apply, and it doesnt have to be perfect, and you can cut patches to fit small or irregular spaces. 3 hints: If youre not using rollers on this after you stick it on the door, youre NOT installing it right; smaller pieces are easier to deal with than large sheets; and keep this in the shade before you apply it, it will get difficult if it gets too warm.

This product is very easy to used and performs as advertised

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.

Great Product. I was replacing the headliner in my Monte Carlo SS and replaced the original thin felt with the Kilmer 80 mil Mats.

It’s cut into lots of sheets. It’s easy to install if you lay it in the sun. I don’t have any oil/asphalt smell in the truck. ProjectTwin has great videos on how to install this stuff. I’d recommend watching them and getting MLV sound deadening material to accompany this. It is my next step.
