Switchable Glass

Switchable glass is just one of many terms that include privacy glass, electrochromic glass, or simply ‘glass that changes colour’ has become an extremely popular glazing solution. Switchable glass is a glass panel that can ‘switch’ between a crystal clear state and an opaque one at the push of a button.

There are three popular methods for achieving switchable glass:
• light exposure - 'photochromic'
• heat exposure - 'thermochromic'
• application of an electric current - 'electrochromic'

Electrochromic Glass

Electrochromic glass switch quickly from clear to opaque at the push of a button. These glass panels contain several thin layers, or ‘coatings’, which can be charged with a large number of lithium ions. When a current is applied, the lithium ions and electrons are transferred from one layer to another, giving the glass a tinted effect. Once the current is stopped, they return, and the glass becomes totally clear again.

Priva-lite Glass

Priva-lite glass is a laminated glass with a liquid crystal film allowing immediate switching from translucent/opaque(off) to transparent(on). The default thickness of the glass is 12mm, but can be varied between 8mm and 22mm. This glass can be used in double and triple glazing, and for internal and external applications.
