80 mil (2mm) 11 sqft Sound Deading Material for Cars, 10 pcs Butyl Automotive Sound Deadener, Car Sound Deadening Mat for Noise Insulation and Vibration Dampening

works as intended. Must be rolled into place to activate adhesion.

I ordered this expecting a true 80mil sound deadening mat, but it's clear the measurement includes the aluminum foil topper rather than just the butyl rubber. The butyl layer feels closer to 50mil, and they seem to make up the difference with a thicker, more rigid aluminum top. While it might help with surface strength, it doesn't match the damping performance you’d expect from a heavier butyl base.

I ordered two types of these insulation panels to compare, and the first part applies to both: I thought these sheets looked nice and professional, and they're not too hard to install. The hardest part is removing body panels or headliner so the surface can be prepped. Panel removal tools like the nylon set and the metal trim pin puller I ordered here are worth the investment even if only working on one vehicle. Next I use degreaser or an alcohol sprayer to clean the area depending on location. A long handled but narrow roller is helpful especially for installing these in the door cavities.The differences between the two are more than I expected when ordering. The adhesive is stickier on the others while these needed heat to activate the RTV adhesive. The other style covered more square footage and had larger foam panels which were easier to cut. This one seems most heat resistant, provided heat doesn't eventually reactivate and loosen the sealant.

I bought this sound deadening mat mainly to quiet down the cabin noise in an older truck that was starting to sound like a tin can on the highway. Between road noise, engine hum, and a few annoying interior rattles, I figured it was worth a shot. I’m really glad I gave it a try because this stuff actually works.Out of the box, you get 10 individual sheets, each backed with butyl rubber and a top layer of aluminum foil with that honeycomb texture. It’s not super heavy, but it feels dense and solid, definitely thicker and higher quality than some other cheap foam soundproofing options. The 80 mil (2mm) thickness gives it a good weight without being hard to handle. I measured it with calipers and it was a little thicker than 80 mil, as shown in one of the pictures.Install was straightforward. I cleaned the surfaces inside the door panels and rear interior wall, cut the sheets to size with a utility knife, and stuck them in place. It doesn't immediately feel super sticky, but I used a roller which helped hold the panels in place. The adhesive is really strong, which is great once it’s in the right spot. Take your time placing it because repositioning isn’t easy. My roller got it to press down firmly, which got it fully bonded with no bubbles or loose spots.The difference in cabin noise was noticeable immediately. It didn't turn my old truck into a soundproof studio, but it takes the edge off of road noise and rattling panels. It also helps reduce heat a bit from the engine and sun, bonus points for that. I especially noticed the improvement on the highway where everything just feels tighter and quieter now.What I like most is how versatile this stuff is. I still had a few sheets left after doing the doors, so I used them behind the glovebox and under the footwell liner. I’ve even seen people use similar mats for home appliances or metal cabinets to stop vibrations.Bottom line: If you’re doing any kind of vehicle restoration, sound upgrade, or just want a quieter ride, this is a good product to start with. It’s easy enough for weekend DIYers to install, it sticks well when rolled in place, and you can actually hear (or not hear) the results. I’ll definitely be buying more when I tackle the roof next.

The media could not be loaded. Seems like a good, strong insulation for installing in my older Jeep doors when we upgrade the door panels.However the adhesive does not have any stickiness. At. All.Will need to determine what product can be used to apply this and not have it slide off as it is pretty heavy.Feeling a bit frustrated at this time & I can not recommend this product at this time.

This stuff will definitely add mass as it's heavy. However I almost think it ends there. I open this up and peeled back the paper because I wanted to see just how sticky it was. The stickiness was very underwhelming. I compared it to a square-foot scrap of dynamat that I had left when I soundproofed my truck. The dynamat is at least 3 times as sticky. I don't have high hopes for vertical or overhead long-term adhesion. I've used a few products over the years but I've always gone back to dynamat. There's a reason why it's 4 to 5 times more expensive.I understand that in order to get proper adhesion it has to be rolled onto the surface. I am simply stating from an initial stickiness standpoint this product isn't promising.
