Is the car front window film applied on the outside or inside?

Car window film is applied on the inside of the car glass. If it were applied on the outside, exposure to wind and rain would cause it to deteriorate quickly. The combination of car window film and glass is like the combination of steel and concrete, merging the advantages of both materials to create an effect far greater than when used separately. Thus, two seemingly fragile materials become incredibly strong when combined. Car window film primarily blocks ultraviolet rays, reduces heat, and prevents injuries from sudden glass shattering. Additionally, it serves to protect personal privacy through the one-way visibility feature of the solar film.
When it comes to the application method of car front window film, I have personal experience—it should be applied on the inside rather than the outside. The reason is that applying it on the outside can cause the film to be scratched by wipers, dust, or tree branches, significantly reducing its durability. You see, applying it on the inside allows it to adhere tightly to the glass, forming a heat barrier that better blocks UV and infrared rays, making summer driving much cooler. During installation, a water-spraying method is used to bond the film to the glass, and bubbles are slowly squeezed out to avoid obstructing the view. There’s also the privacy feature—dark film applied on the inside looks pitch black and mysterious from the outside while remaining clear and visible from the inside. I remember my first visit to a professional shop, where the technician demonstrated the entire process and emphasized that inner application avoids external contamination. Choosing the right type of film, such as heat-insulating or shatterproof, is also crucial, and the correct placement can extend the film’s lifespan by over 5 years. In short, based on performance and aesthetics, applying it on the inside is absolutely the right choice.
