Axis Whiteout film blocks 70% of light and cuts visibility to shadows on both sides of the window. It provides both daytime and nighttime privacy. Whiteout window film makes glass safer if broken, by holding broken glass together, reducing fallout of shards, and is considerably more durable than white paint, which can crack and split in months. This window film is scratch-resistant and uses pressure-sensitive adhesive. Unlike Blackout window film, Whiteout is safe for use on dual-pane windows.
