Is the front windshield film applied on the inside or outside of the car?

Front windshield films are always applied on the inside. If applied on the outside, exposure to wind and rain would reduce the lifespan by at least two-thirds. Additionally, if applied externally, shattered glass fragments from impacts could injure people, failing to serve the purpose of explosion-proof film. Below are specific details about car window films: 1. Introduction: Car window films involve applying a thin layer of material (also called solar film or heat-insulating film) to the front and rear windshields, side windows, and sunroof of a vehicle. 2. Functions: They primarily block ultraviolet rays, reduce heat transmission, prevent injuries from glass shards, and minimize glare. The one-way visibility feature also helps protect personal privacy. Moreover, these films can shield interior items and occupants from UV damage, reflect sunlight to lower cabin temperature, reduce air conditioning usage, thereby improving fuel efficiency and saving costs.
I just had window film installed on my new car, and the technician specifically reminded me that the windshield film is applied on the inside! If it were applied on the outside, the wipers would scratch the film surface when it rains, and the sun exposure could easily cause bubbles or peeling. Moreover, installing it on the inside is safer and won’t affect driving visibility. However, during installation, the glass must be thoroughly cleaned, and the air vents should be covered with protective covers to avoid water damage. Make sure to choose a film with high light transmittance—the one I installed provides excellent clarity at night without obstructing the view at all.
The film is definitely applied on the inside! The exterior of the windshield is exposed to wind and rain, and if the film were applied on the outside, it would get scratched within days. The interior provides a stable and undisturbed environment, ensuring privacy protection without compromising heat insulation. However, the application process is quite meticulous. Last time, I watched as the technician used a heat gun to blow and scrape simultaneously, explaining that precise edge trimming is essential to prevent light leakage. Low-quality films emit a pungent odor, posing significant health risks.
