What impact will it have?

1. Why can’t I open the window?

First of all, let’s understand why it is said that the glass cannot be raised or lowered (or the window opened) in a short time after the car film is applied, and what is the reason behind it.

In fact, because the current film application method is wet pasting, when the film is first applied to the car, the adhesion between the film and the glass is not very high due to the presence of moisture. If the glass is frequently raised and lowered at this time, , increasing friction may cause displacement between the film and the glass, resulting in problems such as edge warping, wrinkles, and blistering.

2. How long does it usually take to open the window?

Generally, under normal circumstances, you will be told not to raise or lower the glass or open the window for 3-5 days (or a week).

So, if you open the windows within a short period of time after the car film is applied, will it have any impact on the use or life of the car film? ① Under normal circumstances, 1-2 times will have little impact. Of course, this is under special circumstances such as membrane deflection; ② If the window is opened many times and displacement is caused, and it is ignored because it is not handled in time, it will last for a long time. It will affect and shorten the service life of the membrane.
