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).
