Now you can convert your existing glass into Smart Glass. Smart Transparent Glass is a laminated glazing comprising two sheets of glass, either clear or tinted, and a STF.
The STF and the glass panes are assembled by means of two interlayer films. Both faces of the film are covered with a transparent, conductive coating. When the power supply is cut off, the STF is translucent and prevents both sides from seeing through the film and vice versa. Thus, switching from ‘Opaque’ to ‘Transparent’ states is almost instantaneous and can be repeated as often as desired.
