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

[MacKyle]

The car film is applied on the inside of the glass, including the front windshield film, rear windshield film, side window film, and sunroof film. Reasons for applying the film on the inside of the glass: It is not exposed to wind and rain, slowing down the aging process and extending its lifespan; the film is less susceptible to external interference during use, avoiding scratches or damage. Functions of the car film: Heat insulation and sun protection to reduce the interior temperature; UV blocking to slow down the aging of car interiors; preventing injuries from accidental glass breakage; creating a private space; reducing air conditioning consumption; enhancing aesthetics; reducing glare. Precautions for film application: Dust is the biggest enemy of film application. If sand particles or fine dust get trapped between the film and the glass during the process, it will affect the quality and effectiveness of the entire film. Therefore, it is essential to choose an automotive service provider with a closed workshop. Additionally, on cloudy days, the air humidity is higher, and suspended particles in the air are significantly reduced, minimizing the risk of impurities between the film and the glass, making it the best time for film application. After the entire car is filmed, sit inside and observe whether the color is uniform, whether there are bubbles, or if there is too much sand. Also, look out from various angles to check if it affects visibility. Methods to test the quality of the car film: Most car decoration shops have a box with a glass side and an internal infrared light source. The film is applied to the glass surface to simulate sunlight exposure inside the car. High-quality films can significantly block heat radiation, and the effectiveness can be judged by hand sensation outside the box.
