The flexible film is rolled up and down on driving rollers (2). The opaque shading comprises a screen to ensure a vision proportional to 50% of opacity. A doubled part comprises height of the window to be completely opaque to remove rolling shutters. The flexible film is tightened between the rollers provided with servomotors (3). The flexible film is provided as a transparent PTFE film having thickness about 26-56 microns.
