What is the warranty period for smart glass/film?
Warranty period is 2 years from date of installation. The life time of the film/glass is up to 10 years depends on varies working environment.
Is smart glass/film a safety glass?
Yes, smart glass/film is a safety glass. Being laminated, it prevents scattering of glass fragments in case of breakage.
Does PDLC smart glass become opaque?
No, the correct term is translucent, since light still gets through, albeit scattered in many directions. The glass would be opaque only if the light was blocked or absorbed.
What Form Factors are PDLC glass available in?
Switchable Toughened Glass
Switchable Laminated Glass
Switchable Double-Glazing
Switchable Window Film
Why does PDLC glass scatter light?
The liquid crystals change their refractive index in relation to the isotropically transparent polymer in which they are immersed, thereby creating multiple step boundaries throughout the PDLC.
It is this change in refractive index at each boundary which causes light to change course. Since the PDLC material contains millions of liquid crystals, each with a boundary facing a slightly different way, the light is scattered in many directions.
The net effect is to hide whatever is behind the PDLC smart glass.
