Should Window Film Be Applied on the Inside or Outside?
1 Answers
Window film is always applied on the inside. If applied on the outside, its lifespan would be reduced by at least two-thirds. Therefore, it is recommended to apply the film on the inside of the car windows. Functions of Window Film: Explosion-proof and Heat Insulation: Car window film involves applying a thin layer of material to the front and rear windshields, side windows, and sunroof. This layer is also known as solar film or explosion-proof and heat insulation film. UV Blocking: Its primary functions include blocking ultraviolet rays, reducing heat transmission, and preventing injuries caused by sudden glass shattering. Additionally, the one-way transparency feature of the film helps protect personal privacy. It also minimizes damage to interior items and passengers caused by UV exposure and, to some extent, contributes to fuel savings. Application Precautions: Avoid purchasing low-quality products just to save money, as they offer no reliability. After prolonged sun exposure, such films often emit a pungent odor, posing significant health risks. Moreover, inferior films fail to provide effective sun protection or UV blocking. After applying the film, avoid rolling down the windows for three days, refrain from washing the car during this period, and do not open the sunroof if the vehicle is equipped with one.
