Review: Blocks the heat! - 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.
Review: Great product - It does work, using it on the inside of my car as a sunroof shade. Cuts the sun and it insulates the roof.

### ⭐⭐⭐⭐ Pretty good insulation barrier
*by D***N on February 29, 2024*

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.
