This heat-repellent film for car windows is an efficient thermal insulator. It uses XIR PRO technology which reflects infrared waves with a wavelength greater than 1,350 mm, thus preventing a rise in temperature in the car interior. The film, in addition, affords further safety protection. The use of an environmentally friendly PET substrate not only reduces glare and improves visibility but furthermore limits the shattering of glass in case of an accident.
