How smart film works.
Our installers apply a thin, self-adhesive layer of PriWatt™ PDLC film to existing glass. It turns clear with power and frosted white when switched off, providing privacy while letting daylight through. Bay Area offices, clinics, lofts and condos can screen views without replacing windows or partitions, with a protective layer that also helps manage sun glare.

How it works
Privacy in a slim PDLC film.
Smart Film Original (PDLC) holds microscopic liquid crystals in polymer between transparent conductive coatings. Power aligns the crystals to provide a clear view. Without power, the film scatters light, creating a frosted appearance that screens the view while keeping spaces bright.
Tiny crystals, a big change.
PDLC means Polymer Dispersed Liquid Crystal. Instead of moving a blind, an electric field changes how light travels through the film.
Lined up, see-through.
Current aligns the crystals so visible light passes straight through the smart film.
Scattered, frosted.
Without current the crystals fall out of line and diffuse the light — the room stays bright, the view disappears.

San Francisco smart film FAQs
How much does smart film cost in San Francisco?
Most San Francisco smart film installations cost $45 to $95 per square foot installed. Glass size, wiring and building access influence the total. Send your measurements for an exact quote within 24 hours.
Can smart film be applied to my existing glass?
PriWatt™ self-adhesive film applies directly to existing interior or exterior glass, including doors and windows, so there's no need to replace it.
What happens to privacy during a power outage?
When power is lost, Film Original turns frosted and still transmits roughly 73% of daylight. Film Reverse stays clear instead.
How quickly does it switch?
The change appears instant: privacy is reached in under 10 milliseconds and a clear view in under 200 milliseconds.
Does privacy mode prevent people from seeing through?
With 95% haze, privacy mode conceals faces and shapes while allowing daylight through. It blocks views, not all light.
Should I install it myself?
We recommend professional installation. Our San Francisco installers inspect the glass, measure carefully and apply the film; a licensed electrician handles the power connection. Busbar and wiring positions are planned before cutting.
How should I clean the film?
Switch off the power, then clean with a soft cloth and 99% isopropyl alcohol. Don't let liquid collect along the edges.
What control options are available?
Use a wall switch, remote, phone app, Alexa or Google Home. You can group panels into zones and set switching schedules as needed.
How long is it designed to last?
Its designed life cycle is over 15 years, with a 2-year limited warranty.
