uxcell 315mil/8mm 16.36sqft Universal Car Heat Insulation Pad Underlay Foam Self-Adhesive Sound Deadening and Auto Dampening Mat 60"x 40" Black Cotton Blends

The adhesive is impressively tacky. If yours isn’t staying stuck then you didn’t do a decent job cleaning the panel surface beforehand. And you DID use a brayer, right? This is good stuff; don’t malign it if you’ve been sloppy.In spite of all the nonsense in the above description (WTF cotton???), this is just neoprene foam that you can stick on big panels to absorb a little bit of noise. It isn’t a miracle product and it can tear but it sticks like mad and you can NOT reposition it after a few seconds.Stick it everywhere. Don’t try for 100 percent coverage. Use it in your car doors to make your speakers sound better. Don’t use it to dampen panel resonance (that’s for heavy thin tarry butyl sheets) but do use this to quiet down spaces.I’m buying more.

I really dont understand why people are complaining about this product. Its fantastic. Yes, it comes folded, which is less preffered to rolled up, but the paper does peel fine as long as you are slow and careful. Ive worked with far worse materials where no matter how careful you were the paper would tear. The foam is super easy to cut, you can even tear it with your hands, however i recommend using an xacto knife and scissors. Im using it alongside some new speakers i got for my 2016 Toyota Avalon which has some unbearable rattling sounds when listening to music. This product helped eliminate 90% of the rattles.

I have a Jeep wrangler that I recently put a new exhaust on which caused the exhaust sound to increase. Jeeps are not exactly quiet; however, the new exhaust system made it hard to have a conversation inside at highway speeds. Also, the exhaust used a larger pipe (which runs under the left side floorboards) and there was more heat on the floorboards. I tried using a thicker carpet insulation which helped the heat issue, but not the sound issue. I installed the foil backed pad on the left front and rear floorboards as I needed more heat protection there and the non-foil backed pad on the right front and rear floorboards. Both types were relatively the same amount of difficulty for installing, but the non-foil backed pad conforms to the floorboard contours much better. The non-foil back pad is also easier to tear and damage (during install and during use). It seems like both pads do an OK job of reducing the heat, but I was more interested in lowering the noise level. I did notice a small amount of noise reduction on the highway, but not really significant. If you are expecting good noise reduction, this will not be what you want. I may try adding some different noise pads on top of this one to see if that helps. I will also put some in cargo flooring to see if that helps. The jeep also has a removable top which is fairly thin. I was hoping that I could use the non-foil pad on that too for insulation, however, it is way too fragile for this application, so I will keep looking for something for the top. I should mention that other folks said that this material arrive folded which made it a little challenging. Mine also arrived folded which was annoying, but I made it work. Others also mentioned that once this is stuck on something, it won't come unstuck. I had the same experience as well. If this stuff is mis-stuck, you are out of luck with removing it and re-sticking it. I cut mine to shape prior to removing the backing. Then removed a little of the backing at one time, stuck it in place, then removed a little more. This worked fine for me.Pros:- Affordable- Relatively easy to install- Sticks well- Seems to cut down the heat- Non-foil version conforms to contoursCons- Doesn't really cut down the noise much- The non-foil pad is fragile. Not sure how long it will last.- Tough to remove once stuck down

Used this one as sound deadening in the trunk and as a padding material for engine cover. Was a bit afraid when using right above the engine, but it performs really well - stick adhered as initially, still soft and spongy. It s a good choice item.

Product came folded in a small bag. Laid out over night so it would lay flat for the install. Wouldn't lay flat has little memory. Creases would not come out and it kept trying to fold during install.Paper backing rips, will not come off with out tearing. Poor quality paperAfter installing I leaned on it and the foam ripped off the adhesive.I will not recommend this product to use.I guess we'll find out if it holds up.I should have returned it and used Butyl sound deadening instead.

Before I begin you should know that this was used for "off" purposes, sound cancelling was not my intention. However as a sound insulator it is terrible, so look elsewhere.I bought this to repair part of my RV. I bought an all weather RV that was not really all weather, resulting in me needing to cut through the thin water proofing on the sides in order to repair and then protect water pipes that were not insulated. However this plastic is like the bottom of a tent, nothing really sticks to it for long. This meant that normal tape to seal it back up were not going to be effective. In comes this, I used it like a large spread of tape covering the entire section that was cut open. It also further insulates the water line.The foam is cheap, but that means it cuts easily too. The backing is paper and if you get it to come off in one piece it is easy to remove, but if it starts to split up then be ready for a PITA backing removal process. But it does make it lightweight.The glue feels like it will stick very well. So much so that my finger touched a spot that when I removed it the foam just ripped apart, the glue stuck to my finger. Repeatedly as I installed it. It did not rip all the way through and the edge that came part was easily cut off the installation. But it shows the glue is stronger than the foam, BUT the foam is cheap as all get out so that does not say much.
