Buy Decorative Film's Silver 15 Daytime Privacy and Sun Control window film is a very reflective window film that enhances daytime privacy. This window film has oneway mirror properties that make it an excellent choice for providing daytime privacy. The daytime privacy effect greatly depends on the lighting conditions and works only when the sunlight makes the outside much brighter than the inside. The effect will be reversed at night since the inside will most likely be brighter than the outside. The Silver 15 is a little lighter in shade than our Silver 5, which makes it an ideal choice if you want the best combination of privacy, sun control, and heat rejection.
