uxcell 21.5sqft Car Sound Deadening Mat Noise Insulation Dampening Shield | 78.7"x39.4", Sound Proofing, Vibration Deadener Panels, Absorbing, Heat Mat, Self Adhesive, Wave Foam Deadening Material

Perfect for keeping your door cards from vibrating against the steel door

Works good. Only wish it came in a roll instead of being folded. It has fold creases.

The material seems fine, the problem is it comes folded up so small and tight, vacuum bagged after folding, that it tears itself on the creases. I set it out in the sun trying to get it to be less smashed down but still just smashed mushy foam. I was able to mist it with water and kinda steam it back to shape like with upholstery foam but it only kinda worked. Definitely would find something else instead of this. Should be rolled and not vacuum bagged.

Excellent sound deadening. Used on the inside of the door card of my GR86 when upgrading the speakers. The material feels very high quality and the adhesion made it very easy to install. The large roll makes it easy to cut the size you need for clean application. High recommendation.

Noticeable improvement over using just Dynamat alone

This isn't stuff you would use in a studio, but I used it to put a border around my door frame to keep out some of the noise from the living room. It works great for that; the back has a sticky adhesive that is easy to take off the wall if needed. So far it is serving the purpose, give it some consideration.

Absolute garbage for 40 bucks couple of feet of material. It comes folded wrinkled with stretches and cuts. Not something you can use in studio or car interior. Not worth it's money and definitely not as neat and good looking as on their ad pictures. Home depot has the same foam for like 20 cents fer feet. Get some $4 glue and save your money. Do not fall for pictures this product is garbage

Perfect size

Lo he instalado para aislar acústica y térmicamente la caja de la persiana del dormitorio principal ya que tenemos ventana con vidrios acústicos pero se notaba algo de ruido por arriba ya que la caja de la persiana viene con un aislante simple en la tapa solamente y he de decir que a nivel acústico ha mejorado bastante, reduciendo algo el ruido ambiental exterior "ojo, no te deja la habitación como un ataúd de silencio...". Viene plegado tal y como veis en las fotos lo cual no es un problema y para la instalación, lo más complicado es el momento de pegarlo ya que la cola que tiene adhiere muchísimo con lo que tienes que tener algo de mañana para no estropear la espuma si te toca despegarla ya que arrancas la parte con cola... Para mí uso se merece las 5 estrellas

Je l'ai utilisé pour ne plus entendre le tic tac d'une alarme et ca a fonctionné

Great soundproofing really does its job

Not as good

Todo correcto tal y como se describe
