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.

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 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.

I installed Kilmat in my Toyota Camry SE; which as any Toyota Camry owner can tell you the road noise is quite loud. I did the entire trunk, and all of the doors, including the inside of the skin of the door, and the door panel itself. I will say this product is fantastic at blocking noise and deadening sound vibrations. Installation is easy and definately get the rollers (espeically the small one) as they make a huge difference. My aftermarket stereo really came to life after applying Kilmat generously on the doors; the bass came to life and the nuances in the music could now be heard. The Camry is much quieter now and the doors have that quality thump when you shut them. the outside noise is now at a minimum; and you can tell you are sitting in a quiet car. The nice thing is that you do not have to blast the music to hear the nuances; which is great for my daughters ears. I found most reviews here say that there is no smell; this in my experience is completely untrue. Perhaps there may be an off-gas period that needs to happen, but the inside of my Camry smells like tar or perhaps a glue smell. However, the smell is not repulsive or strong, but definitely present; its like someone farted in the seat and you sat in the seat and got that whif.... opening the windows relieves the strength of the smell for a bit. I left the windows open today to deal with the smell; and I did the trunk a few days ago and it still smells. I have read that Kilmat is not asphalt based, which is great, but beware that after applying you may smell it for a while. To be fair, it has only been a few days since applying, so I will update this review when the smell disappears as I expect that it will. I would and will continue to purchase this product as the value of what this does for the price is great. I plan on doing my 4Runner next.

Ive been aware of products like this, but never personally used any of them... Until now. This in combination with the Noico 315 Red did great things for a 1999 Dodge Ram 1500 4wd SLT. I covered the inside of all four of my doors with a layer of Kilmat 80 plus a layer of the Noico 315 insulation covering that. The interior side of all doors were completely covered with Kilmat 80, then finally the door panel got a layer of Kilmat 50 over about 60% of its surface. The roof and back wall got a layer of Kilmat 80 plus a layer of Noico 315. I live in the desert and highs in the 110s are a given during the summer. I know these products have improved the cabin environment substantially. Nothing but the sun blasting bare metal then various trim panels on that metal was stock fare in my truck. Im guessing a 10 to 15 degree decrease over stock. Right after I finished the doors I was waiting at a stop light. A trash truck was backing up about 100 away from me. Everyone knows the piercing backup warning beeper. That tone was muffled quite a bit. I havent done the firewall or floor yet. That can wait until the weather cools. My Focal Flax 6.5 components have always been enjoyable, but they sound much more lively than before. The sound system performance has been improved on every level. Highs, lows, mids...everything is better. Doors have a solid feel when closing now. These products are a system multiplier when used correctly. I believe its important as upgrading the various components in any system. A couple other things, I had zero issues with adhesion. This stuff sticks on a 100 degree day just fine! As far as odor. Yes there is a mild tar smell during installation. It dissipates after a couple days. A small, temporary price to pay, for the overall benefits.

Easy to apply and I will recommend it to anyone it does the job and no more rattle thank you kilmat mp

I mean you get what your paying for. My car already has almost 36 cubic feet of Ballistic deadener. That’s my last piece , and I want to say that one weighs about the same as 5 sheets of the Kilmat. As you can see the kilmat will take up more space. That might good for some, but I’m pushing my Jetta hard for SPL and I been getting some very annoying rattles still. So there’s a few spots I missed with the Ballistic, but I wasn’t trying to spend $200 on more of that so I got this kilmat. I’m sure it’ll get me there right. However I’m 99 percent sure if I originally got kilmat I’d be very unsatisfied . I didn’t want to wait on shipping or pay too much. There’s only the roof and a few odds and ends left to do so I’ll just double it. If your just trying to remove trunk rattle for a 500 to 1200 watts setup this might be ok for some. Maybe the doors . But if your like me, there’s going to be much more you’ll need to do, this aint gonna work

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)

I just applied this to my 3rd Gen 2018 Toyota Tundra Crewmax, which has a big cab you should know and it sounds better and I can see some noise cancelling coming from this. I used 2 packages total and for my all my door interior panels, back seating and back panels and I need to order another set. There was a smell that lingers for a couple of days but it literally disappears after that! Every review made it seem like it was unbearable but truth is that once you get it applied just apply some air freshening deodorizer and itll go away within a few days. It sounds fuller and quieter. Everything on any new car, except a rolls royce I guess, gets a ton of exterior noise level! The adhesion is good as long as you got a reliable roller too by the way. I have yet to do my firewall, driver side and transmission/center console hump so thats next. If Im doing the headliner, Im going to consider doing a insulator and sound Deadened for that instead of the kilmat. And a note for anyone with open and spacious big cab or interior, please consider ordering more than just what they recommend on their sizing. I followed that suggestion and I really recommend ordering a couple more than expected. For Tundras probably a good 4 packages if you are doing all everything. And if youre on a budget so far this is the best way to do it.

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!
