How long after applying window film can the windows be used?

[Evie]

It is best to avoid rolling the car windows up and down for 5 to 7 days. After applying car window film, the heat-insulating film needs time to firmly adhere to the window. During this period, opening and closing the windows can cause the edges of the newly applied film to curl, and the film, which hasn't fully bonded yet, is prone to displacement. Here is some relevant information: 1. Window film can block direct sunlight from the driver's line of sight, especially during midday when external glare significantly affects driving visibility. Strong light can cause temporary blindness, and the film effectively filters out this glare. 2. Additionally, some window films can reduce the amount of ultraviolet rays that enter the car directly. Window film can also prevent the shattering of window glass into fragments, which could injure passengers inside the car. Flying glass shards are undoubtedly a ticking time bomb, and the film acts as a protective layer that holds the glass together, preventing shards from scattering even if the glass breaks.
