BuyDecorativeFilm 48 in. x 100 ft. RPRGY Premium One Way Mirror Heat Control and Daytime Privacy Silver/Gray Window Film RPRGY1048100 - The Home Depot

BuyDecorativeFilm's One Way Mirror Silver Window Film series are highly reflective window films that enhance daytime privacy. 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. During 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.
