Privacy Smart Glass Technical Details

  • Privacy glass uses a film of liquid crystals sandwiched between two panes of glass. When a small amount of electricity is applied through this film and the power is on, the liquid crystal molecules align allowing incident light to pass through and the glass appears transparent.

  • When the electrical supply is removed and the power is switched off, theseliquid crystal molecules relax into a random orientation. This diffuses and scattersthe light that is transmitted through the glass and the Privacy Smart Glass appears opaque (private).

  • Sizes:
    Minimum: 200mm x 200mm. Maximum: 1,800mm x 3,500mm.
  • Glass colours:
    Clear, bronze, grey, green, blue tint.

How is Smartglass cleaned?

Cleaning can be carried out in much the same way as normal glass by using a slightly damp cloth or professional glass cleaning product.  Abrasive products should not be used as these may scratch the glass surface.  Excess water should not be used and the Smart Glass should be in the off state when being cleaned.  Any excess water should be removed before switching the Smart Glass panel on.

Yes, special consideration must be given to framing, sealing, location of transformer and type of switching mechanism used.  Please contact us for specific details.
