Input:
Question: Is this Mylar Reflective Film transparent?  Could I put it over a window to block the sun but still see out?
Document: For the price you can't beat what you get. I covered a whole 5'x3'x8' room and still had plenty left over. Very reflective, very easy to use, great value!
This is by far the best deal for mirror film that I've found. This mylar is durable and the coating is about as reflectant as one could expect.Please note that this film is not 2 millimeters thick, it's 2 mils thick ( .002 Inch ).The only question now is how long will the material and finish last in direct sunlight.If you are searching for solar reflector material for either focusing the sunlight to a target or just reflecting it away from a specific area this film is a good deal.
Answer: yes
