Switchable Smart Film: Your Windows, Now Switchable

Switchable PDLC film retrofits existing interior glass: windows, partitions and doors go clear to private in under a second. No glass replacement, often one day.

Phase Glass provides switchable privacy glass, retrofit PDLC smart film and laminated smart glass for residential and commercial projects.

Switchable PDLC film is applied to existing interior glazing (windows, partitions, doors, enclosures) turning it into switchable privacy glass without replacing a single pane. Installation is often completed in one day.

Most existing interior glass is.

We confirm suitability during planning. Suitability is confirmed by survey.

The same switchable technology, applied to your glass.

Smart film carries the same PDLC liquid-crystal layer used in laminated smart glass. Instead of being sealed inside a new panel, it is professionally applied to the interior surface of glazing that is already in place. Powered, the film is clear. Switched off, it turns private in under a second.

Survey the glass

We confirm suitability: glass condition and type, edge access, frame detail, and a route for low-voltage power.

Plan power and control

A low-voltage power and control plan, with zoning per panel, per room or per elevation.

Apply the film

The film is applied to the interior surface of glazing that stays in place, then connected to a concealed power supply and the controls chosen for the project.

Commission and switch on

The system is tested and prepared for clear-to-private operation before handover.

Glass doors that switch when someone is home.

Because the existing glass stays, retrofit film is the practical route for finished homes and occupied commercial spaces: no demolition, no reglazing, and a fraction of the disruption.

Where switchable privacy film earns its place.

Existing Bathroom Windows

Add on-demand privacy to street-facing glass without losing daylight.

Office Partitions

Turn existing glass-walled rooms private for confidential conversations.

Glass Doors and Sidelites

Privacy at the entry without frosting the glass permanently.

Conference Rooms

Retrofit occupied offices with minimal disruption to the workday.

Healthcare Partitions

Instant patient privacy on existing glazing, easier to clean than curtains.

Storefront Interiors

Switch interior display glass from open to private in a single touch.

Discreet power. Your choice of control.

Nothing demolished, nothing reglazed. The glass stays; the privacy layer, power and controls are added.

Glazing being replaced anyway? Specify laminated smart glass instead.

New construction, remodels, new partitions and enclosures are specified as factory-laminated switchable panels with the layer sealed inside.

Questions and answers

Can switchable film go on my existing windows or glass?

Usually, yes. Switchable PDLC film can be applied to most existing interior glazing: windows, partitions, doors and enclosures. We review the specific glass as part of every project.

How long does smart film installation take?

Installation is often completed in a single day, depending on the number of panels and site conditions. We confirm the timeline during project planning.

How is switchable film controlled?

A wall switch, remote, app, or building control system switches the film from clear to private in under a second, with multi-zone control available. Controls and electrical requirements are reviewed during planning.

Does the private state make the room dark?

No. The PDLC layer scatters light rather than blocking it, so rooms stay bright and daylit while sightlines are cut off.

When is laminated smart glass a better choice than film?

When the project involves new construction, a remodel, or glazing that is being replaced anyway, factory-laminated switchable panels are typically specified instead of applying film to existing glass.

How do I get pricing for switchable film?

Share the application, approximate dimensions and photos of the glass. We review the requirements and return project-specific pricing with our recommended configuration.
