I ordered the 8ft piece because I wanted to put it across my three panels of sliding doors that go across my living room. The sun comes onto that side of the house after 12:30 and really heats things up. Prior to this I had used mylar sheets clipped to the curtains. They worked some, but I wanted something thicker. This has a really nice thickness and I have just stood it between the curtains and the glass when the sun is shining hot. Great product.

This product works great for the money.. great for windows to reduce heat.

This was one big sheet. I used it to cover the house windows from the cold weather. It did work for heat retention. had to cut it to fit my 3'x3' windows. able to cover 3. The velcro sticky's worked well.

It’s a little annoying at first because it comes folded and there are seams. They do work well though.

It’s not on a roll — it comes folded. I used it in my camper, but I don’t think it reflects the sun well enough. I can still feel the heat coming through. I did find it easy to cut and install.

Excellent, and thick! I used this to make a custom fitted solar heat shield for my sunroof skylight and it works excellent, I used a foam block as the backplate and a section of this that goes up against the window. Its a lot of material that covers a lot of space

Absolute trash. It shows it coming as a roll but it's all folded up in a vacuum sealed package. This makes it nearly impossible to get a nice clean fit on a flat surface. Secondly it's about a 16th of an inch thick but looking at the pictures on the website you think it was firm enough to stand up by itself. I don't know why Amazon allows this trash on their website.
