Glazing with ordered opacification, product type SGG PRIVA-LITE® from Saint-Gobain Glass, changing from non-transparent to transparent by the application of an electric voltage of approximately 100 V AC.
SGG PRIVA-LITE® is a laminated glass panel made of 2 extra clear glasses and a liquid crystal interlayer film (LC Film). The film is sandwiched between two interlayer films and assembled between the glass panes. The components are laminated together to form a compact assembly.
When switched OFF, the liquid crystals are randomly positioned, giving the glass a translucent, milky white appearance, and preventing through vision.
When switched ON, the liquid crystals orientate themselves in the same direction; the glass becomes transparent and allows vision through it. Switching between ON and OFF states is almost immediate.
