How many days after applying new car window film can the windows be opened?

[VonAlyssa]

For a newly applied car window film, it is recommended to wait 3 days in summer and 7 days in winter before opening the windows. During this period, avoid rolling the windows up and down arbitrarily, as doing so in a short time may cause the film to shift due to incomplete drying between the film and the glass. After applying the film, park the car in a sunny area to facilitate the evaporation of moisture within the film, and avoid washing the car for three days. Car window film is a thin layer applied to the front and rear windshields, side windows, and sunroof of a vehicle. This layer, also known as solar film or heat insulation film, primarily serves to block ultraviolet rays, reduce heat, prevent injuries from shattered glass, and reduce glare. Additionally, it provides privacy protection through its one-way visibility feature. Furthermore, car window film can minimize damage to interior items and passengers caused by UV exposure, lower the interior temperature through physical reflection, reduce the use of car air conditioning, and consequently decrease fuel consumption.
