GOSCHE 394mil Sound Deadening Material for Car – 16 Sqft, 10mm Thick Closed-Cell Foam for Noise Reduction, Vibration Dampening, Heat Insulation, Peel-and-Stick DIY Installation (15-Piece)

Great product for a great peice. Very easy to put and stick to the bare metal of the vehicle to greatly reduce road/wind noise and add some insulation (especially in the hot region of the U.S.). Mock up, cut to size, peel and stick.

I decided to rip out the interior of our Ford F250 Super Duty to install sound deadening mat directly to the floor. I am bad at math and thought I could get by with one pack of the 9.8" x 15.7" pieces but should have gotten two packs. The adhesive is super strong and the material is very thick. This sound deadening mat was a great value and it has lots of uses. It's really effective at quieting road noise and I recommend it.

This works very well. I used a roller to smooth it out while putting it in the cab of a truck for sound proofing. It reduces the noise very well. The product is very easy to work with too. I would buy again over more expensive options.

Great product, good price. Use this product around my car doors, and around my speakers. Easy to work with and sticks very well. Great for noise reduction, easy to cut, and help stop the vibration.

This product does excellent. I put it in my F150 and my subwoofers don't rattle at all. All you hear is fantastic music. It is also a huge money saving item. There was enough to cover the back of my cab and then more. I am going to put it the doors of my truck as well. There is no odor at all, it seals well against any surface. I also used it to protect my RCA cables from interference. Great product.

Use these in my van, the whole box. Certainly does the job!

Working on a 51 Ford pickup. I used this to insulate the firewall and rear of the cab. It sticks like crazy, however repositioning is not possible. The glue is stronger than the foam, so trying to remove it results in the foam tearing. I did a test by shining a halogen light at the flat sheet metal at the back of the cab. In 1/2 hour the sheet metal had gotten 45 degrees hotter. The insulated inside temperature on the insulation increased less than 1 degree. I looked for this because I have found that folded self stick insulation tends to delaminate and is hard to get smooth. This is easy to apply and conforms well to contours. I would use it again.

Does the job well for sound deadening and reducing heat. Very sticky. Overall a good product but I am concerned about it being fire resistant.
