Smart Film, PDLC Film & Smart Glass Alternative — Complete UK Reference Guide
A UK technical and project-delivery guide to smart film, PDLC technology, specification, cost, installation and sector applications. Published by PriviFilm, a PriviTechnologies brand, with UK distribution, training and project delivery provided by Forti Nova.
Direct technical answer
What is PDLC smart film?
PDLC stands for polymer-dispersed liquid crystal. PDLC smart film is an electrically switchable film applied to suitable flat glass. With the matched power off, its liquid crystals scatter light and the film appears frosted for visual privacy. When energised, the crystals align and the film changes to its clearer state.
It is designed for controllable visual privacy; it is not automatically a blackout, acoustic, security or solar-control product. Exact clarity, haze, voltage and power use depend on the specified film grade.
Who supplies and installs smart film in the UK?

Smart Film, PDLC Technology & Privacy Film — Complete Glossary
Every term used in the smart film, switchable glass, and electric privacy film industry — defined clearly for architects, specifiers, facilities managers, and homeowners.
How Does Switchable Smart Film Work? PDLC Technology Step by Step
PDLC Film Structure
Polymer Dispersed Liquid Crystal molecules are suspended in a polymer matrix, sandwiched between two ITO (Indium Tin Oxide) conductive layers — the same core technology found in factory-manufactured smart glass.
Off = Opaque (Privacy Mode)
Without electrical current, liquid crystal molecules are randomly oriented — scattering light. The film appears frosted, creating the default privacy state. Exact visible-light transmission and haze depend on the selected grade.
On = Clear (Transparent Mode)
Apply the matched AC supply and the liquid crystals align, changing the film to its clearer state. Optical and switching performance are confirmed against the selected product grade.
Smart Film vs Smart Glass — Same Technology, Different Delivery
Retrofit PDLC film and factory-laminated PDLC smart glass use the same liquid-crystal switching principle, but their construction and optical performance differ. Smart glass has PDLC laminated inside a factory-made glass unit and requires glazing replacement; smart film is applied to suitable existing glass. Compare the selected product specifications, survey requirements and whole-project costs before choosing a system.

Smart Film vs Smart Glass — Cost, Installation & Performance
| Factor | Smart Glass | Switchable Smart Film ✓ |
|---|---|---|
| Technology | Switchable layer built into a new glass unit | PDLC film applied to suitable existing glass |
| Whole-project cost | New glazing plus installation | Retrofit priced to existing panes |
| Installation route | New glazing package | Retrofit to assessed existing glass |
| Glass Replacement Required? | Yes — full glazing removal | No — applies to existing glass |
| Disruption | High — structural glazing work | Minimal — no glass removed |
| Privacy performance | Depends on the selected glass unit | Similar privacy brief; optical appearance varies by grade |
| Retrofit Suitability | Not suitable for retrofit | Designed specifically for retrofit |
| Warranty | Varies by product and supplier | Written terms for the quoted PriviFilm grade |
Smart Film vs Blinds — Why Electric Privacy Film Replaces Traditional Blinds
Traditional Blinds — The Problems
- ✕ Dust accumulation — impossible to fully sanitise (critical in healthcare)
- ✕ Mechanical wear — cords fray, slats break, periodic replacement
- ✕ Visual clutter — even when open, obstruct sightlines
- ✕ Manual inconsistency — staff adjust differently each time
- ✕ Ongoing maintenance & replacement costs
- ✕ Not suitable for glass partitions — add bulk, reduce light
Electric Privacy Film — The Solution
- Smooth film-on-glass surface — cleaning method and edge detail checked for the project
- No blind mechanisms, cords or fabric folds
- Clearer when powered on — sightlines and light preserved
- Instant, consistent privacy — same every time, every switch
- Minimal ongoing cost — no replacement parts or cleaning service
- Designed for glass partitions — flush, architectural finish
How Much Does Smart Film Cost? Smart Film Cost vs Smart Glass Cost
Smart film can be a cost-effective retrofit on suitable existing glass. A fair comparison with factory-made smart glass must include the whole scope: glazing condition, replacement work, access, preparation, controls, electrical work, programme, edge protection and written warranty terms.
Smart film cost factors: total area (m²), glass complexity (flat, curved, or irregular), electrical controller type (wall switch, BMS integration, remote, automation), site accessibility, and regional installer rates. PriviFilm projects range from single meeting rooms to multi-site NHS trust rollouts — contact us for project-specific smart film cost.
Running costs: PDLC film consumes electricity in clear mode and no operating power in its unpowered opaque state. Confirm the quoted system consumption, cleaning method, inspection needs and applicable warranty terms for the actual project.
