Transparency or privacy.
Windows allow us to see and be seen. Sometimes, however, we may prefer to remain invisible.
PRIVA-LITE®, the “intelligent” glazing system, offers you this privacy in the blink of an eye, by means of a simple electric switch.
Thanks to its revolutionary technology, PRIVA-LITE® can be transparent, like normal glass, or milky white with the appearance of etched glass, creating an atmosphere of intimacy.
And it’s as easy as switching on a light.

| The liquid crystals |
|
 |
SGG PRIVA-LITE® is a laminated glass consisting of two leaves of float glass, colourless or coloured, between which there is a film with liquid crystals. This film (LC) and the panes of glass are assembled with two interleafed PVB butyrals.
|
|
 |
The polymer and the liquid crystals are dispersed in the LC film. The two faces of this film are coated in a transparent layer which is an electrical conductor. Each layer is in turn connected by means of a conductor filament to a flat electrical switch, located on one of the long sides of the glass, a few millimetres from the edge.
|
|
| Just switch it on and it’s ready! |
|
|
|
 |
When there is no current passing through the PRIVA-LITE®, the liquid crystals in the LC film are unaligned and scatter the light in all directions.
In this state, the PRIVA-LITE® is translucent, with a milky-white and practically opaque appearance, giving all the privacy you need.
|
|
 |
When the electrical field is activated (approx 100V AC) the liquid crystals are oriented and aligned, and PRIVA-LITE® becomes just like transparent glass. The glass goes from translucent to transparent almost instantly, and the process can be repeated as often as you want.
