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

Good quality. Easy to cut, easy to apply. Rolls on easy. Good adhesive. Lowered the cabin road noise in my Mustang and lowered the cabin db of the exhaust. Installed with a full custom audio system. Would purchase again.

Use this on my 2026 Tesla model Y juniper for sound deadening inside the doors when I had them apart to install self presenting door handles and soft close door latches. There is essentially no sound deadening in the door other than a pathetic little piece of sticky foam right in the middle of the large expanse of sheet metal on the inner door as it comes from the factory. Despite them upgrading the new model Y with acoustic glass, I feel that internal door sound deadening such as this, is mandatory to prevent "tin canning". It seems to subjectively make a huge difference as my wife states that it is probably 80% less noisy in the car since I did this to all four doors. Highly recommend this as it is both effective and economical.

I used this in my 2rd gen Cummins. I had always heard about the added weight and whatnot (not that it matters in a diesel truck), but it wasn't overly heavy to me. I did a crew cab truck with 1.5 boxes, so the coverage per box is solid. It's easy to work with and adheres very well. I can tell a big difference from the cab drone now vs before, also a lot less rattles and shakes. Very glad I decided to do it.

This is a good product. Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product.

Sticks well. Not as nice as Siless version. If I were buying again I would just buy extras Siless 120 mil, they are around the same price but the value is better with Siless's thicker panels even though you get less total coverage per pack. Can be cut to size easily, we used a box cutter which got a little gummed but but not too bad. we were able to get it in and around everywhere we needed to put it and it held up well as we were mashing it into weird spots. It doesn't smell hardly at all while being applied and once its on there is no smell whatsoever The product is good for what it is. 4 stars only because I think it gets oversold for how much this alone can do. We did notice a slight reduction in noise but nowhere near the multiple decibels we see claimed everywhere. If your vehicle is mostly quiet but just has that little bit getting through this will probably do wonders, If you have a vehicle where there's significant engine noise in the cabin you'll need more than just this to bring that down.

Really good product for the price, I used it on the doors in my 2008 civic SI. It sticks really well and does a good job of deadening vibrations and adding mass. It forms to things and cuts well, but still holds enough of a shape to not seem floppy or cheap. The doors seem a lot more solid and sound good when they close compared to before.

Amazing and high quality that sticks very well. Sound deadening is amazing with this, just make sure you use enough layers by doing the “knock” test. I had to use 4 layers inside the area near the wheel well because it was very hollow and this product solved the issue. Subwoofers in the trunk sound great and much more cleaner instead of ghetto trunk rattle.

So if your buying this, you're either killing road noise in your vehicle, or installing a sound system in a vehicle. Let me start buy saying...is it as good as Dynamat? No. Its not...BUT.....please continue reading. Dynamat, at the time of this review, is 5x the cost of this stuff, and its NOT 5x better. its only VERY slightly better. And honestly, BOTH are Butyl Rubber, so the only thing that makes the dynamat better, is its a hair thicker. I bought 3 boxes of the stuff for around half the price of 1 box of Dynamat, and I would do it again. I am building an older mazda truck, and I put 1 layer on the inside of the door skins and roof, 2 layers on the back wall, and 3 on the floor and firewall, and its SILENT inside the truck. It stopped ALL the vibration, sheetmetal reverberation, and the drum effect from thin sheet metal. Its nice and thick, it cuts easy, and sticks well. A couple of pointers before you install it.... Vacuum out all the dust. you want the best possible contact from the rubber to the surface of the panel. Get the installation roller. You can do it without it, but it makes mashing it down a lot easier. Don't waste time fitting it like a jigsaw puzzle. I was trying to do that because I assumed it would give a better end result, until my audio installer friend came over and just told me overlap it and call it day. Its getting covered with panels, and the more weight from the deadener the better. Ended up taking all the little cut parts and sticking them on the firewall. This stuff doesn't look, feel, or act like a cheap "store brand knock off". Get a box and try it before you spend a fortune on "name brand" stuff that is the exact same material with a different logo. Highly recommended. Will buy more if I need it in the future.

Muy práctico fácil de instalar, fácil de cortar, tiene muy buen peso se aprecia de calidad, el adhesivo pega muy bien ya instalado le da fortaleza y cumple, muy recomendable

I purchased this for insulating both my door panels and the back of the door cards during my audio system install. I'm no expert, but this product was easy to cut, easy to install and had noticeable results. Road noise was reduced vastly, which was the main goal for this project.

Werkt goed & plakt goed. Doet wat het beloofd

Excellent

El producto es bastante bueno y a un costo razonable aunque comparándolo con el mismo producto marca de Amazon es superior y más resistente el de Amazon aunque esté cumple con el objetivo, creo si reune las 3 b de bueno bonito y barato, sin duda lo volveré a comprar
