Smart Glass / Switchable Privacy

PDLC technology transitions from opaque (frosted) to fully transparent in under 100 milliseconds. Privacy is the default unpowered state — maintained during power failure. 5-7 W/m² when clear.

Overview

Smart Glass — Instant Privacy

PDLC (Polymer Dispersed Liquid Crystal) film contains billions of microscopic liquid crystal droplets in a polymer matrix. Unpowered: crystals are randomly oriented, scattering light to create a frosted opaque appearance (privacy). Powered: voltage aligns the crystals and light passes through — the glass becomes clear and transparent. Switching takes less than 100 milliseconds. Power consumption is just 5-7 W/m² when clear, and zero when opaque. Can also be used as a rear projection screen in opaque state.

Site Care for Switchable Glass

Everything that applies to ordinary sealed units applies here, plus one rule that outranks the rest: the cable is not a handle. Never lift, drag or hang a switchable unit by its flying lead, and protect the cable-exit corner as carefully as the edges.

  • Store upright, dry and covered — moisture near the cable exit is the enemy. Suckers above 25 kg, mechanical above 60 kg.
  • Fit within 28 days, above 5°C, and let the unit reach room temperature before first power-up. Test switching before final trim-out.

Lead time: 10-15 days — PDLC film is made to order.

FAQ

Common Questions

Maximum panel size is 1500 x 3000mm. Larger glazed areas are split into multiple panels with independent switching.
10-15 working days. PDLC film lamination takes longer than standard glass processing.
Smart Laminated (11.5mm) fits a standard laminated glass rebate. Smart + DGU (31.5mm) matches a standard sealed unit rebate depth, so no frame changes are usually needed.
Privacy is the unpowered default state. If power is lost, the glass returns to its frosted, opaque appearance automatically.
Clean as standard glass with no abrasive products. Keep the control wiring and connections protected from moisture at the frame junction.
