No distracting shutters and drapes that harbour ducts and bacteria

Beauty and functionality combined

How Does it 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 Applications

What happens if there is a power failure?

As Polyvision is turned ON when in transparent mode, 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.
