Window film is a thin laminate film mounted on the interior or exterior of glass surfaces. These thin films are made of vinyl, polyester, plastic, ceramics, and other material that allow the light to pass through it, and are installed on the windows of homes, offices, hospitals, boats, cars, and aircrafts.Glass has low reflectance for room temperature radiations, which causes loss of thermal energy from buildings, whereas it has high transmission of the solar radiations, which increases the energy necessary for cooling buildings. Architectural window film on the glass reduces the emissivity and control solar radiations
