394 Mil Car Sound Deadening Mat, Sound Deadener Material 13 Sq Ft, 12-Piece | 10 mm Thick Automotive Material, Sound Insulation And Vibration Dampening, 9.8 x 15.7-Inch Sheets

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.

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.

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 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.

The 15 of 394 mil was enough to surround both wheel wells in my van, and I had 2 full pieces left over that I used elsewhere. I used 2" aluminum foil tape to seal all cuts/joins. I found the adhesive to be adequate but not excessive. It works best on bare or painted metal, but also adheres to wood. It is flexible enough to adhere to rounded edges, if the curve is significant you may need to cut out a small triangle so it sits flat. The silver material is of good quality and doesn't easily tear. I haven't driven the vehicle yet to know how well it does to reduce road or suspension noise.

Seems to be a pretty good sound deadener for the money. Purchased it to cut the noise from my 1967 Dodge’s roof. Wanted something that wasn’t as heavy as Boom Mat to adhere to the interior roof. Moderately dense, foam-based material. Much thicker than butyl sound deadener (this is close to 1/2” thick). Easy to work with and conform. Had best results cutting with large, sharp scissors and using upholstery adhesive on the roof before peeling and sticking this on. Happy with it for the roof but would I personally not use for the floor. Too thick and spongy for me. Will not cut the sound as much as a butyl material but still cut exterior noise noticeably.

Cheap and falls apart easily the amazon basic is 100x better than this is I had not purchased this would have never worked . I stacked 3 amazon basics side by side ( as i needed 2sq feet for my small electronic drum set ) it came at perfect sized . Then I placed 2 of these on top of that and a final layer of amazon basics because unlike this the aluminum top is not trash . I literally set my drum stand on this sn it tore thru the " aluminum heat shield they call it lol !!! it only weighs 10lbs . Anyway with the amazon basic its together . Is sound proofing well and doing its job .. The main thing is this is a center material nothing can be set on it as it is very flimsy . the amazon basic is like dynomat for cars .. Together they work well

Sticks, for now, dampens the sound very well, hopefully it remains stuck. The adhesive paper and the over all quality is not the best.

Applied this foam sound deadening material over a thin layer of butal based sound deadening. Extremely sticky, but so effective. Front driver area of my Ford E250 is So Much Quieter now.. can hear the stereo now. Highly recommend this.

Excellent insulation material. I used it for my house wall insulation, and it keeps me warm and cozy.

easy to install, simple to use, not as effective as I was hoping. when cutting foam (even with a fresh usility knife blade, the control interface doesn't cut cleanly the whole way. maybe scissors would be better
