Smart Switchable Glass
Electrochromic / PDLC glass that switches from clear to opaque (frosted) at the touch of a button. Instant privacy for boardrooms, bathrooms, hospital wards and luxury residential interiors.
Trent Glass Smart Switchable Glass is laminated glass with an embedded liquid-crystal (PDLC) film that switches from transparent to opaque when power is applied — clear when energised, frosted when off (or the reverse, project-dependent).
