How many days should you avoid rolling down windows after car window tinting?

[Val]

How many days you should avoid rolling down windows after car window tinting depends on the season. In summer, refrain from rolling windows up or down for 3 days, and in winter, for 7 days. Car window tinting involves applying a thin film layer to the front and rear windshields, side windows, and sometimes the sunroof. This film is also known as solar film or heat-insulating film. The primary functions of car window film include blocking ultraviolet rays, reducing heat transmission, preventing injuries from shattered glass, minimizing glare, and providing privacy protection through its one-way visibility feature. Additionally, car window film helps protect interior items and occupants from UV damage, lowers the car's interior temperature through physical reflection, reduces the need for air conditioning, and consequently improves fuel efficiency.
