Good cheap sound treatment
For the price especially this stuff is great! when I needed a little extra to finish a project and didnt wanna buy more dynamat, this stuff came thru. Easy to stick, seems to be pretty sticky not coming off. Great Value!

Needs to be layered, Great product
Good product Butt!! It’s best to use this on top of aluminum sound deadening material because it’s does not help with sound but it does help reduce heat off the roof. I used it on my 1969 Volkswagen bug. However I did use this first and had to remove it all and layed down some other sound deadening material and then this.

Works well for lightweight sound deadening.
Not great at reducing road noise or insulating heat but i paired this with boom mat spray since i didnt want to add significant weight to my car and my door panels stopped rattling. Helps stop door panel rattle and body rattle in my opinion. Its good for a lightweight budget insulation but if you want max insulation go with butyl mat, this stuff, and some mass loaded vinyl.

Decent job, could be more sticky.
I added this lightweight foam to the large doors on my coupe. Original soundproofing was small, I added large patches before the original strip, and after. I’ve noticed a big improvement in road noise, as my coupe door is about 3-4 feet long estimating. I also added it to the trunk lid. Closing the lid now sounds better and less “tin like” than before. Overall I’m surprised how much it helped. It may not have made it overall more quiet, but it deff changes the type of sound your hearing which sounds more dampened than before.

Affordable sound barrier
The insulating roll was purchased to cover the interior hood of a car. The factory insulation was sagging and not staying in place, causing a nuissance when servicing the vehicle. The insulation was easy to installvafter cleaning the mating surface. Although thinner than the factory insulation, it foes a better job in reducing the audible engine noise and appears to insulate heat very well. I did not buy enough for my project and required a second roll. Definitely recommend it as it works well at a fraction of what similar insulation rolls cost.

Cumple de sobra
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

Dun maar prima
Snel geleverd, gunstig geprijsd, maar vooral erg fijn product. Het is dun, dus verwacht geen mega effect maar daardoor juist ideaal in beperkte ruimtes. Zacht aan de buitenkant en vlot te knippen en plakt goed. Aanrader.
