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

Automotive front windshield film is applied on the inside. Below is relevant information regarding whether the front windshield film should be applied on the inside or outside: 1. Reason: Because the glass film itself is very thin, applying it on the outside would significantly reduce its lifespan due to exposure to wind and sunlight. Applying it on the inside provides better protection and, in case of an accident, can help hold shattered glass together, preventing injuries from flying glass shards. It does not serve as an explosion-proof measure. Therefore, it should be applied on the inside. 2. Function: Vehicle window tinting involves applying a thin film-like material to the front and rear windshields, side windows, and sunroof. This layer is also known as solar film or explosion-proof heat insulation film. Its main functions include blocking ultraviolet (UV) rays, reducing heat, and preventing injuries from sudden glass breakage. Additionally, the one-way visibility feature of solar film helps protect personal privacy. It also minimizes damage to interior items and passengers caused by UV exposure and, to some extent, can contribute to reducing fuel consumption. Therefore, it should be applied on the inside.
