MOTUKA 40" x 80" 198mil Reflective Insulation Foam Thermal Panel Heat Shield - Aluminum Foil Finish, 21.53 sqft

It does work, using it on the inside of my car as a sunroof shade. Cuts the sun and it insulates the roof.

The material did what I needed, enough to complete the job, appears to be what I needed to insulate the cabinet against outside cold, all went well, job done

Despues de unos dias de uso se empieza a disolver el reflejante, se empieza a romper y es muy delgado. Compré mas o menos unos 5 y fué dinero tirado a la basura. No lo recomienda NADA, no tiren su dinero.

My house gets a lot of heat from the south wall in the summer. I decided to cover most of it with some kind of insulation. I bought three different kinds and this was one of them. This one worked the best for my purposes. I just taped it near the top of the wall and hung it down lengthwise. I checked using an infrared camera and it was working way better than a similar material that I also tried. So I ordered three more to finish off the wall. I oriented them shiny side in, because there are windows and I didn't want to blind people outside. So they get the white side instead of the mirrored side. A little bit of faint bluish light comes through the material from the windows in the daytime.

Works as a foam barrier should . Lost a star because it comes folded up vs a roll as showed in pic. Reflective material & foam gets creased. Not a deal breaker though since I’m cutting it up. Others wanting the whole sheet flat might be upset.
