Can window film be installed on the outside of a window?
The application of window film to the outside surface of some windows may also be considered. Most window film manufacturers make a few products for exterior applications. As these films are subjected to an extreme amount of weathering and may easily be abused because of their location, or as a result of careless window cleaning, they have a somewhat limited life. These products generally have limited warranties for shorter periods of time. Weather conditions need to be considered in the installation of exterior window films. When an exterior application is needed, high winds, cold temperatures (ouside air temperature less than 40 degress F), rain and snow can prevent installations from being scheduled.
