Here we answer the most frequently asked questions about switchable smart glass, including how it works and what smart glass can be used for.

What Is Switchable Smart Glass?

Switchable smart glass, often just called smart glass, is a type of glass that switches between see-through (like normal glass) and frosted (which can’t be seen through) at the touch of a button.

The change in smart glass is instantaneous, like flicking a light on and off and adds a dramatic feature to any room. Smart glass allows you to manage light levels and privacy. The frosted glass can even be put to other uses, like serving as a projection screen (more below), making smart glass a versatile update to traditional glass.

How Does Switchable Glass Work?

Switchable smart glass contains a layer of liquid crystals within the glass. When smart glass is turned off, the crystals in this layer are randomly oriented and they scatter light that comes through the window making it opaque. 

When smart glass is activated, an electric current is passed through the liquid crystal layer, the crystals line up and allow light to pass through making the glass appear clear. This is why switchable smart glass is opaque when turned off and transparent when turned on.

What Is Switchable Smart Film?

Switchable smart film works in the same way as switchable smart glass, but it’s an adhesive film that can be applied to existing windows or other transparent surfaces. This allows you to instantly transform your windows, skylights, partitions, acrylic screens, plexiglas, or other transparent areas into smart glass features.

How Is Switchable Smart Glass Controlled?

Smart glass is usually switched between opaque and transparent using a switch or button. However, you have other options – smart glass can be activated with a voice command or controlled via your phone or other mobile devices.  

Is Switchable Smart Glass The Same As Privacy Glass?

Yes. Privacy glass is another name for switchable smart glass. Other names include electric glass, switchable glass, liquid crystal glass, , and electronically controlled windows.

What Can Smart Glass Be Used For In The Home?

Switchable smart glass has a wide range of uses in the home. Smart glass can be used in external windows and skylights to help manage light levels and to balance privacy. 

This is only the start of using smart glass in your home however, as it also creates stylish internal partitions and can be used in walls and doors to bring more light into rooms.

What Can Smart Glass Be Used For In Retail And Business Settings?
