One-way graphic window film is an excellent way to advertise on your car, truck or business windows while at the same time adding privacy and protection against the glaring sun. Perforated window film, or "Window Perf", is very similar to the vehicle wrap and window vinyls that you see on the bodies of cars and trucks or on building windows and walls. The only difference is that this material has just been perforated - small holes have been made throughout the material. The perforated pattern allows the full graphic image that is printed on one side to be easily seen, and still allows viewing through the window from the other side.

Drivers prefer the material because their view remains unobstructed, unlike with decals or lettering. [caption id="attachment_356" align="alignright" width="150" caption="Bank Window Graphics"][/caption] Window Perf is easily removable from glass surfaces, and it is recommended that windows that have received a Window Perf application remain closed throughout the life of the application. Rolling down or opening windows can cause the vinyl to start to lift. For all Window Perf applications on vehicles, we always use an "optically clear" film over-laminate that is applied to the printed sides of the material after printing. This film laminate serves three purposes: 1. The optically clear film laminate protects the prints at the time of installation, and against minor scratches. 2. The optically clear film laminate protects the prints against fading caused by the sun. 3. The optically clear film laminate provides a smooth surface over the perforations. Without this film, rain water would build up in the tiny holes and cause both visual interference as well as damage to the material. Interested in adding a Window Perf billboard to your vehicle?
