Is the car film applied on the outside or inside of the glass?

[HoldenFitz]

Car window film should be applied to the inside of the car glass. Applying it on the inside avoids exposure to wind and rain, ensuring the film is not subjected to significant external interference during use. If applied on the outside, it could be damaged by wipers or soaked by rainwater, leading to bubbling of the window film. Here are some details about car window film: 1. Car window film is a thin layer applied to the front and rear windshields, side windows, and sunroof of a vehicle. This layer is also known as solar film or heat-insulating film. 2. Its main functions include blocking ultraviolet rays, reducing heat, preventing injuries caused by shattered glass, reducing glare, and, due to the one-way transparency of the film, protecting personal privacy. 3. It can minimize damage to items and passengers inside the car caused by UV exposure. By reflecting sunlight physically, it lowers the interior temperature, reduces the use of air conditioning, thereby decreasing fuel consumption and saving costs.
