Avalon decorative window film creates a stunning look for sidelights and windows. The Avalon etched glass window film significantly improves privacy while allowing for some visibility through the glass. The white parts of the Avalon Film are Lite Frost and and the decorative lines are 1/8" clear. See pattern detail image below. Not a true one way film but it does have a similar effect since it is easier to see out than in during the daytime.
