Electric films for glazing

The film contains a layer of liquid crystals dispersed in a polymer. Without current, the crystals are randomly oriented and scatter light in all directions: the film is opaque, milky white, like frosted glass. When an electric current is applied, the crystals align instantly and allow light to pass through: the film becomes transparent.

The switch takes less than a second. There is no stable intermediate state by default: it is either transparent or opaque. However, with a suitable dimmer, you can adjust the opacity level by varying the voltage, allowing semi-transparent states to control light and privacy.

Consumption is low: about 5 watts per square meter in transparent mode. In opaque mode, the film consumes nothing since it is not powered. This is the opposite of a motorized blind, which consumes power while moving: here, the film only consumes when it is clear.

The adhesive film is applied dry to the inner face of existing, thoroughly cleaned glazing. A qualified professional then connects the electrical contacts built into the film edges to a low-voltage transformer. This allows switchable opacity to be added without replacing the glazing.

The integrated version places the film between two glass panes to form a ready-to-install glazing unit. The finish is cleaner: no visible film edges, no visible cables, with connections integrated into the frame. This is the preferred solution for architects in new builds and high-end renovations. Standard or custom sizes available.

Control level adapts to the project. At the simplest level, a wall switch turns the film on and off. One click, the glazing becomes transparent. One click, it becomes opaque. This is enough for a meeting room or medical office.

A remote control allows you to operate the film from a distance, useful for high or hard-to-reach glazing.

Home automation integration offers advanced possibilities. The film can connect to KNX, Crestron, Loxone, or any standard home automation protocol. You can program scenarios: opaque when the projector turns on, transparent when the meeting ends, semi-transparent at the end of the day to filter low-angle sunlight. The film becomes part of a smart building.

Glass meeting rooms are the main use case. Transparent when available, opaque when a confidential meeting begins. No more Venetian blinds that break or permanent frosted films that close off the space.

Medical offices and healthcare spaces use the film for on-demand privacy. The practitioner makes the glass opaque during consultations and transparent between patients. The switch is instant and silent.

High-end hospitality uses the film for shower walls, bedroom partitions, and spa areas. Guests control bathroom privacy via a wall switch. It adds a premium feature that makes a difference.

Showrooms and exhibition spaces use the film as a scenographic tool. The glass switches from transparent to opaque to create a reveal effect: hide the product, obscure, then reveal it. It also works as a projection screen.

Executive offices, video conferencing rooms, phone booths, and VIP spaces complete the main applications—anywhere privacy needs to be adjustable without compromising aesthetics.

In opaque mode, the film forms a uniform white surface that works as a projection screen. You can project onto it from behind or in front. The image quality is comparable to a standard projection screen. The glazing becomes a window, a privacy wall, and a presentation screen all at once.
