SGG Priva-Lite in a Transparent State 

Imagine a glass that lets you decide how private you want it to be? A glass that gives you the freedom to make it transparent? A glass that you choose to be translucent? Sounds too good to be true? With Saint-Gobain Glass, anything is possible!Welcome to the world of SGG Priva-Lite, a world that can switch from public to private – all in the flick of a switch!


Let’s know what this Priva-lite is all about. A smart glass, SGG PRIVA-LITE is a laminated glass comprising two panes of glass, either clear or tinted, and a liquid crystal interlayer film. Its unique technology allows it to be switched from an ordinary-looking clear glass to a whitish translucent glass, ensuring optimal vision control.


When the glass is switched off from its special power supply (transformers provided), the liquid crystals are randomly scattered, preventing both sides from seeing through the glass. By switching the glass on, the crystals line up and reorient themselves, turning the SGG Priva-Lite totally transparent.


SGG Priva-Lite is tested to comply with the CENELEC European Standards and can meet stringent security requirements. The laminated glass ensures a high degree of safety, and combined with the Saint-Gobain Glass' range of bullet-resistant glazing; it can prove to be an efficient, anti-bandit glass. It is ideal for hiding precious items that are intended to be revealed only to a selective audience. Clocking a low electricity consumption, SGG Priva-Lite comes with a 5-year guarantee.
