What Is Switchable Glass?

With just the flick of a switch, Polyvision Switchable Privacy Glass is transformed from cloudy opaque to completely transparent glass. The smart glass can be installed as a wall, dividers, windows and pretty much anything else you can think of.

What Are The Benefits Of Switchable Glass?

Privacy and security with architectural integrity

Visual attention to interior and exterior design

No distracting shutters and drapes that harbour dust and bacteria

Beauty and functionality combined

Serves as a projection screen and has glass board capabilities

Infrared radiation and UV ray protection

Can be retrofitted

How Does Switchable Glass Work?

Polyvision PLDC Film is sandwiched between two layers of glass and various adhesive interlayers before being cooked in a high-pressure oven. This binds the two layers of glass together, encapsulating the inner layers.

Electrical wires exit two or more corners of the laminated glass, which are connected to a transformer and a power source.

When electricity is applied, the liquid crystals inside the glass laminate orientate on a molecular level that allows light to shine through. When electricity is turned off, the crystals scatter and the Polyvision Switchable Privacy Glass returns to its dormant, white opaque state (Privacy mode).

Polyvision Switchable Glass Applications

What happens if there is a power failure?

Polyvision is turned ON when in transparent mode, and the product will return to its original state (Opaque – Privacy Mode) in the event of a power supply failure, therefore not compromising the users’ privacy.
