uxcell Heat Sound Deadening Insulation Mat Deadener Pad Car Auto Exhaust Muffler Hood Door Waterproof 394mil 6.5sqft 40x24inch for Car Hood

This stuff works. I have an old, cheap car that was very loud. I put this under the headliner and it is much quieter. It also doesn't seem to get as hot. The backing is very sticky, just unroll and remove at the same time. Well worth it, need to put some on the door panels next.

Good product

Sticks great...easy to cut and fit.

This has good adhesive, easy to cut shapes. Worked perfect as firewall insulation my John Deere 318 Garden Tractor.

Easy to work with,heat block and sound block

The material is fine. The issues are caused by packaging. Unike the image which shows a roll, my package was folded twice in both directions causing severe rippling. I streched it out flat with tension for over a week but adhesion was still not good. I ended up installing it with limited bonding

Used this to reduce heat and noise from our dryer. It works as expected! For the price, I think it's worth it. Very good noise reduction.

Used on my CLEAN under car armor panels and it quiets better than the original. I used a super weather adhesive to prep the area before I went to apply it. I now believe that was unnecessary as the adhesive back material is very good. Just clean the area with MEK or like solvent cleaner and let dry well. Material glue sticks to scissors and I found a harbor freight razor knife and piece of wood for a cutting board works great. I think surface prep is key to a good install. I got the thick stuff and the sound absorption is really good. I think it would work great on a door or firewall.

It's OK, perhaps a little too thick, it's not very strong either and if you apply it and want to move it, nope. It just tears off. So it's what it costs sort of thing. I'd recommend a thinner more expensive version of this.

Utilisé pour refaire l'insonorisation de la tôle entre moteur et habitacle,côté moteur, d'une clio. Posé il y a quelques mois, le collage n'a pas bougé et l'effet insonorisant est réel. De plus, cet isolant n'a pas l'air d'intéresser les rongeurs qui avaient déchiqueté celui d'origine (genre de laine minérale compressée) sur ce véhicule qui dort dehors en campagne.

I bought this to replace the foam under the engine cover, it's really sticky and did a great job. Also used to sound proof in the boot so a great product.

Excellent. Used in boat hatch firewall

The sourcingmap Heat Sound Deadening Insulation Mat is smaller than advertised, which was disappointing. The material feels cheap and the sound insulation performance is underwhelming. It didn’t make much difference in reducing noise as I hoped. Not great value for the price—would recommend looking for better quality options elsewhere.
