Buy Decorative Film's One Way Mirror Silver Window Film series are highly reflective window films that enhance daytime privacy. If the One Way Mirror window film is installed on a window, it gives the window a mirror-like, reflective appearance on the outside for the unwanted onlookers while still allowing the people inside to see the outside scenery through the window during the daytime. However, there is an important fact to note about the One Way Mirror film. The film provides a mirror-like appearance only on the side that is silver and when it is considerably brighter on this side. For example, during the daytime, the sun makes the outside much brighter than the inside of a building, so the outside of the window (the side that's exposed to sunlight) will look like a mirror, giving passersby a view of nothing but their own reflection, while people can still see through the window from the inside. In contrast, during nighttime, the interior lighting of your home or office will allow people outside to see inside, and it will be harder for you to see outside because the inside of the building will be much brighter than the outside. The Gray-Silver 10% (10% = Dark) is gray on the inside. From creating a professional, formal setting to simply adding a feeling of calmness to your living arrangements, Buy Decorative Film's Silver-Gray One Way Mirror window film serves as an excellent choice.
