Car Sound Deadening Material Mat - 197 mil 8.7 sqft Auto Audio Deadener Foam, Sound Dampening and Heat Insulation for Truck, Vehicle

Works well, easy install, very sticky

Best quiet for your buck! Easy to cut and apply. The difference in road noise is easily noticeable.

Good material and camein as described. Adhesive is strong and in time see if it last. I used it to cove the ceiling in the truck before installing the headliner.

Awesome!!!!!!!

These were perfect for what I needed them for. I have a Honda Fit that, by the factory, has near no sound insulation and is terribly loud when driving down the road. These were thick enough to be effective but not so thick that it kept my interior trip panels, headliner and console from obstructing them from going back on. The pill-and-stick feature was easy and fast. The paper backing was not only easy to remove but gave a surface to draw on when transferring over a pattern to cut out. Plus, they cut super easy with a good pair of all-purpose scissors, not once clogging up the blades with adhesive residue. The adhesion also seemed super strong even on the underside of my roof sheet metal. After using these over a good portion of the inside of my car, concentrating above the exhaust, the firewall and the roof sheet metal, my car is not only much quieter, but it now also gives the impression of a more solid driving car. I wasn't expecting that and it was a bonus. If you have the knowhow and time to take apart an interior to get to the car's interior sheet metal. I highly recommend these stick-on insulators. But I cant give feedback on engine compartment or outside of the interior use. I have no experience if they'll hold up to direct heat or moisture.,...For what I used them for.... 5-stars all the way

The material is not very dense. The amount of sound deadening is questionable. The foil skin is too thin and tears easily.

I used this stuff to reduce some of the noise while I'm driving. It has helped to reduce the outside noise. Just be careful. The stuff is very sticky. It barely touches the surface, and it sticks to it quickly. Besides that overall really good stuff.

I really have no verifiable proof but man, my JL Sub gain has reduced by 20% for the same interior experience , Exterior sounds, definitely less , heavy and hard to maneuver, even .5 inch, difficult. In the end, total satisfaction
