Window film is a modern, functional, and fashionable material that is used for a variety of functions at home or work. It is made of polyethylene terephthalate (PET) or thin vinyl and glued directly onto plain, untextured glass. The effective life of the window film is determined by the type of film used, the type of glass used, the construction of the window, the orientation of the glass compass, and the location of the building. Also, window films are a type of window treatment applied to windows and glass surfaces, designed to reduce the amount of solar heat transmitted through the glass. Unlike curtains or blinds that need to be closed to be effective, window films are designed to allow light in, help increase solar reflectivity, reduce heat and glare, and maintain your view, all at the same time.
