Standard PDLC Film
Private when unpowered, clearer when powered. The glass holds its private state by default and is switched toward transparent when the room needs to open up, which suits spaces that are private most of the time.
Smart Film
Smart Film & Switchable Privacy Film in Los Angeles
PDLC switchable film that changes between transparent and private modes using electrical power — for offices, conference rooms, clinics and homes across Los Angeles.
Common reasons clients reach out
Smart film projects usually start with glass that needs privacy only part of the time.
Meeting rooms that are open one hour and confidential the next
Consult rooms that need privacy without losing daylight
Glass walls where frosted film would make the change permanent
Interiors where blinds and curtains do not suit the design
Spaces where the privacy requirement changes through the day
The basics
Transparent and Private Modes
Switchable film can change between transparent and private modes using electrical power. The default state and powered state depend on the selected film system: standard PDLC is typically private when unpowered and clearer when powered, while reverse configurations can operate in the opposite way.
- In private mode the glass is translucent — daylight still passes through, but the view through it is obscured.
- In transparent mode the glass returns to a clear or near-clear view, depending on the film system.
- Switching is immediate and can be repeated as often as the room needs.
- The right system depends on which state the glass should hold when nothing is switched on, including if the power is interrupted.

Film types
Standard and Reverse Switchable Systems
Reverse Switchable Film
Transparent when unpowered, private when powered. The glass stays clear by default and is switched to private on demand, which suits spaces that are open most of the day and need privacy only for part of it.
Choosing between them
The practical question is which state the glass should hold when nothing is switched on, including what happens if power is interrupted. Neither sequence suits every project, so we confirm it for the specific system before anything is ordered.
What both have in common
Both change between transparent and private modes electrically, and both need a power supply and a control method at every panel. The default state is what separates them.
Choosing a film
Which operating sequence fits the space
| How the space is used | Usual system |
|---|---|
| Open most of the day, private occasionally | Reverse switchable |
| Private most of the time, opened when needed | Standard PDLC |
| Glass should stay clear if the power is off | Reverse switchable |
| Glass should stay private if the power is off | Standard PDLC |
| Bathroom, ensuite or permanently private glass | Standard PDLC |
| Not sure which state should be the default | Decided from how the room is used |
What this service solves
What smart film solves in each space
Offices
Interior partitions and perimeter offices that need to look open most of the time and close down for part of it. The film goes onto the partition glass, so the layout of the office does not change.
Conference Rooms
The most common request. The glass stays clear in normal use and switches to private for confidential meetings and presentations — no blinds to pull and nothing added to the design.
Clinics and Medical Offices
Consult rooms, reception glazing and interior windows that need privacy at specific moments while keeping daylight and a clean, non-clinical finish.
Residential
Bathrooms, ensuites, street-facing glass and interior glass walls in homes where fixed frosting would be permanent and blinds would not suit the space.
Power
Transformer, Controller and Power Supply
Smart film is an electrical system, not only a film. It requires power, a transformer or power supply unit, and a control method, and that side of the project is planned before installation rather than after.
- Every panel is connected, so the equipment locations are part of the design rather than an afterthought.
- The transformer or power supply and the controller need a position that stays accessible for service and is close enough to the glass for the cable run.
- The control method for the room is agreed at the same time as the equipment locations.
- Equipment positions and cable routing are confirmed before material is ordered.
Electrical
Wiring and Electrical Work
The film has to be connected to power, and that work is planned around the building rather than around the glass. Cable routing, the position of the equipment and the switch, and who carries out the connection are all settled before installation starts.
- Cable routing is simplest when the wall or ceiling is still open, so new builds and remodels are the easiest case.
- On existing partitions the cable has to reach the frame or mullion without becoming visible, and that is usually what decides the layout.
- Electrical connection may need to be completed or coordinated with a qualified electrician, depending on the project.
- Electrical work is estimated separately from the film and its installation.
Limitations
Glass and Installation Limitations
Smart film is more constrained than standard architectural film, and the limits are worth knowing before the design is fixed. Panel size, seams, glass compatibility and installation conditions depend on the selected smart film system and are confirmed before material is ordered.
- Wider glass can require more than one piece, so where a seam would fall is reviewed against the panel layout.
- The glass has to be clean, flat and in sound condition, which is checked before anything is ordered.
- The electrical connection sits at the edge of the film, so the frame or mullion has to be able to conceal it.
- Where a room does not suit a switchable system, a fixed privacy finish is often the better answer.
Cost
What Smart Film Costs
Smart film installation starts from $60 per sq ft. Electrical work is not included. It sits in a different price bracket from standard architectural film because it is an electrical product rather than a film alone.
- The final cost depends on the panel sizes, the system selected, the number of panels, the control method and the electrical work involved.
- Electrical work is estimated separately, because it depends on the building rather than on the glass.
- We confirm the figure for a specific project after seeing photos and panel sizes.

What it does
- Switches between transparent and private modes on demand
- Keeps daylight in the room in both modes
- Replaces blinds, curtains and fixed frosted film

- Is not a solar-control or heat-rejection product on its own
- Does not add sound insulation between rooms
- Does not change its default state after the system is selected

Process
How a smart film project works
1. Send photos, sizes and how the room is used
Share the glass or partition, rough width and height per panel, and what the space is used for. How the room is used is what decides the operating sequence.
2. Choose the system and operating sequence
Standard PDLC or a reverse configuration, based on which state the glass should hold by default and what should happen if power is interrupted.
3. Plan power and controls
Equipment locations, cable routing and the control method for the room are agreed before anything is ordered.
4. Arrange the electrical connection
Electrical connection may need to be completed or coordinated with a qualified electrician, depending on the project. It is estimated separately from the film.
5. Order the film
Smart film is made to the panel sizes for the project, so it is ordered for the job rather than taken from stock.
6. Installation and handover
Panels are installed, connected and checked in both modes, and the controls are handed over with care instructions.
FAQ
Smart film questions
How does smart film switch between transparent and private?
Switchable film can change between transparent and private modes using electrical power. The default state and powered state depend on the selected film system: standard PDLC is typically private when unpowered and clearer when powered, while reverse configurations can operate in the opposite way. The switch itself is immediate and can be repeated as often as the room needs.
What is the difference between standard PDLC and reverse switchable film?
The default state. Standard PDLC is typically private when unpowered and clearer when powered, so the glass holds its private state unless it is switched. A reverse configuration works the other way — transparent when unpowered, private when powered. Neither suits every project, so which one is right depends on how the room is used and which state the glass should hold by default.
What happens if the power goes out?
The film returns to its unpowered state, and which state that is depends on the system: standard PDLC goes to its private state, while a reverse configuration goes to its transparent state. That is one of the main reasons the operating sequence is decided before anything is ordered.
Does private mode make the room dark?
No. Private mode is translucent rather than opaque — the view through the glass is obscured while daylight still passes through. If the goal is to block light or black a room out, that is a decorative or blackout film rather than smart film.
Can smart film be installed on existing glass?
In many cases, yes. The final recommendation depends on the glass condition, size, wiring access, controller location, and whether the project is residential, office, clinic, conference room or commercial space. Panel size, seams, glass compatibility and installation conditions depend on the selected smart film system and are confirmed before material is ordered.
Is smart film a heat or glare product?
No. Smart film is a privacy product — it changes what can be seen through the glass, not how much heat comes through it. Where heat and glare are the problem, solar-control film is the right answer, and the two are specified separately.
Where is smart film normally used?
Offices and interior partitions, conference rooms, clinics and medical offices, and residential glass such as bathrooms, ensuites and interior glass walls. The common thread is glass that needs privacy for part of the time rather than all of it.
How much does smart film cost?
Smart film installation starts from $60 per sq ft. Electrical work is not included. The final cost depends on the panel sizes, the system selected, the number of panels, the control method and the electrical work involved, so we confirm the figure after seeing photos and sizes.
Do I need an electrician?
Smart film requires power, a transformer or power supply unit and a control method, so there is an electrical side to every project. Electrical connection may need to be completed or coordinated with a qualified electrician, depending on the project. We confirm what is involved once the equipment locations and cable routing are agreed.
