SGG PRIVA-LITE is a laminated glass containing a liquid crystal (LC) film assembled between at least two plastic interlayers. The liquid crystals align when the electrical current (100 VAC) is switched on, causing the glass to turn transparent instantly. When the power is switched off, the glass has a naturally opaque appearance, blocking vision (total privacy), yet permitting light to pass through (translucent).


Where can it be used?

Any interior area where there is a need for both obscuration or transparency depending on the circumstances, for example, screens, glass doors, partitions, room-dividers, kiosks, security (e.g. banks), conference rooms, cubicles etc.


Partitions to ensure privacy at will, for meeting rooms, bathrooms, kitchens, entrance halls or security checkpoints (banks, hospitals, post offices, police stations, etc)

  • Back-projection screen
  • Swinging or sliding door with the view temporarily obstructed
  • Floor or ceiling tiles (under certain conditions)
  • Advertising or branding on buildings at certain times of the day (dynamic façades or display windows).


  • Partitions, doors and sliding doors, floor panels, counters, display cases, bank screens etc.
