Sound Deadening Mat 157mil(4 mm) 18sqft - Car Sound Deadening Material Closed Cell Foam - Heat Insulation PE Foam Sound Deadener Material & Heat Barrier

The material was well packaged and arrived in good condition. The material is easy to work with, and the adhesive is very sticky. The material is very easy to cut and apply. I applied it to a metal cabinet that had a tinny ring to it before the application. After applying the material, tapping the cabinet produced only a dead "thump". I believe the material will work very nicely as a deadener.

Very sticky backing. Once it down ,its down. Good sound barrier, and help the vibration of the gas tank I carry on the truck.

Perfect for applying underneath slot car track to deaden sound. Quick delivery!

This worked perfectly to patch under hood insulation that was shredded by a squirrel. I just needed a small amount and this was a reasonable solution.

I used this to put around my transmission tunnel. Seems to have done the job. Easy to apply and its very sticky. I would buy again

Not bad in terms of noise dampening but once cut and removed from the back the foam starts to shrink and deform. Also if you want to remove it without any traces afterwards good look this stuff is impossible to remove without residue.

Awesome stuff , and very easy to install

Works awesome! Highly recommend this product and brand

Consegna veloce. Materiale perfetto per le mie esigenze, un po' acustiche e un po' isolanti termiche per l'auto Facile applicazione.

Con el rollo de 1,67m², me ha dado para aislar bastante un Peugeot 206. Pude hacerle pasos de rueda, puertas y parte del maletero, y la mejora es muy notable. No lo ha dejado silencioso, pero porque ni he hecho todo el coche, ni soy profesional y porque en general y por construcción del vehiculo va a haber ruido en el habitáculo. Pero realmente es mucho menos, antes en una nacional a 90 ya hablaba casi gritando, y ahora puedo mantener un tono normal. Fácil de instalar, solo hace falta tiempo que dedicarle al asunto en un sitio para hacerlo tranquilamente

I bought this AggSound 4 mm sound-dampening roll specifically to quiet my Bambu Lab P1S 3D printer enclosure, and it exceeded expectations. The material is dense, flexible, and easy to cut, making it simple to line the inside panels. The adhesive backing grips firmly but still allows a bit of repositioning during installation—no messy glue required. Noise reduction is dramatic. After lining the enclosure, I measured roughly a 30–40% drop in operating noise, and the harsh high-frequency vibrations from stepper motors are almost gone. The printer now runs with a deep, muted hum, which is a huge improvement for a home office or shared workspace. The roll size (170 × 33 cm) was ideal—plenty to cover the P1S panels with some left over for small accessories. The 4 mm thickness strikes the right balance: thick enough to absorb vibration but not so thick that it interferes with door seals or airflow. Overall, the quality and performance are outstanding. If you want a quieter, more professional-sounding Bambu Lab P1S (or any 3D printer or enclosure), this AggSound sound-dampening material is a must-buy upgrade.
