While retail signs and posters hung in windows can be highly effective, they can also block light and obscure merchandise displays placed near the window or entrances. See-through window graphics are a great alternative. They maintain a strong graphic impact from the outside, and from the inside are practically invisible.
Perforated window film has a grid of tiny holes that are imperceptible when viewed from distances. This type of film is also commonly used in car wraps for back and side windows.
The film also helps reduce glare, heat, and UV light. For retail displays, window film or window graphics are amazing for point of purchase (POP) billboards, as they prevent window clutter and are easily interchangeable for a new look or seasonal promotion as needed. At night, when backlit these signs light up for a potentially stunning effect and around the clock exposure.
