HOW LONG WILL WINDOW FILM LAST?
The effective life of window film will vary by the type of film, type of glass, window construction, compass orientation of glass, and in which part of the world the building is located. There are documented cases of film lasting 12 to 22 years or more in some instances. This should not, however, be assumed to be the normal expected life. All quality window films for residential and commercial use are warranted by the film manufacturers for a minimum of five years (certain products may have extended coverage). The warranty includes an address to contact the manufacturer directly should any questions arise either before or after the installation of the window film.
The life expectancy of GILA window film depends upon the type of film, its exposure to the sun, the climate, and its cleaning and maintenance. With average care, the Heat Control and Privacy films should have an expected life of up to 15 years. The longevity of film is usually the result of direct exposure to UV rays (part of sunlight). The older the film, the less UV it can absorb effectively. If UV protection is an important reason for using film, we recommend replacing the film every five years. By that time, the protection level has gradually decreased from 99% to about 70% UV reduction, depending upon direct sun exposure.
