Window with variable transparency

The variable transparency window is a unique product in Bertrand's offer. It is electronically controlled glass with adjustable transparency. A simple click is all it takes for an opaque glass wall to become transparent.

ELECTRONICALLY CONTROLLED GLASS WITH VARIABLE TRANSPARENCY

This glass is a laminated safety glass based on liquid crystal film technology. In the opaque state it has a natural, matte appearance. When the power supply is restored, the crystals are rearranged, as a result of which the glass becomes immediately transparent.
