Is the car film applied on the inside or outside?
2 Answers
Car film is applied on the inside. Here is some relevant information about car film: 1. Benefits of applying car film on the inside: From a physics perspective, applying the film on the inside reduces light transmittance and increases the tension of the car glass, which can mitigate external forces. Even if the glass breaks, it won't shatter into small pieces. 2. Car heat insulation film: Car window tinting involves applying a thin film layer to the front and rear windshields, side windows, and sunroof. This film is also known as solar film or heat insulation film.
I once made a funny mistake when applying car film myself—I thought sticking it on the outside would be easier, but the edges all curled up after rain. Now I know the film should be applied to the inside. The outside is exposed to dust, rain, bird droppings, etc., which can quickly damage the film. Applying it inside protects the film from direct exposure, and it’s easier to smooth out bubbles with a squeegee. When cleaning the window, make sure to thoroughly remove grease and wipe it dry with some cleaner. My friend applied film on the outside, and it started bubbling in less than two months—he regretted it so much. I’ve applied heat-insulating film myself, and it made summer driving much cooler, but don’t choose a color that’s too dark—nighttime safety is more important. Professional shops usually recommend applying film to the inside for longer lifespan and easier maintenance. After application, avoid rolling down the windows for a few days to let it adhere properly. Overall, the inside is the right choice—it saves money and hassle.
