Window tinting is the phrase usually used to describe the process of applying window film to car windows or flat glass in homes and buildings.
Window tint or film is constructed of one or more layers of polyester film darked or dyed with a variety of components to achieve different results. It is coated with an adhesive and generally applied to the inner surface of windows to reduce heat, light and improve aesthetics. Thicker versions are used as a safety film to help prevent injuries and to slow intruders.
Having glass tinted can generally reduce the need for air conditioning and can pay for itself over time in residential and commercial applications. Many modern window films are able to achieve a great amount of heat reduction without as much visible light reduction compared to the window films of the past.
Installing window film is not a do it yourself job. Window tinting requires acquired skills and should be installed by professionals.
