With only 7% of the total space as clear lines in the Boardwalk design, this geometric window film provides considerable privacy, especially from the outside. The simple frosted square design is perfect for homes and offices where some privacy is desired. Similar to one way films, you'll find it much easier to see out than anyone can see in. It's kind of an optical illusion from the outside. The light reflects back off the white window frosted film and makes it difficult to see through the clear areas. At night, the reverse is true.
