Back to what this was set up for.

With the heat in Texas spiraling as it usually does in the summer, I have been applying heat film over my french doors and windows.  From the outside in daylight, no one can see in, but you can see out.  At night you will still need shades or drapes.  And it makes a tremendous difference in the amount of heat that come in through the windows and doors.  I found it at Home Depot online as that is the only way I shop now. 

It blocks 72% of sun's heat and it blocks 99% UV rays to help prevent fading.  I am sold and am going to do all my windows.  Do  not remember what I paid for this roll but it was economical.  Next I will show you what accessories you need to put this up.
