From Clear Glass to Blackout at the Flick of a Switch
PriWatt CLC (Colorant Liquid Crystal) is a new type of Smart Glass. In the off-state - it appears as a neutral gray-black, providing functions such as light blocking, shading, and privacy protection. In the on-state - it becomes transparent with clear visibility and a wide viewing angle.
Ideal for outdoor use, these units are perfect for windows, doors, and facades, enhancing design aesthetics while ensuring energy efficiency and effective environmental control.

Film Reverse (PNLC) is clear when the power is off and turns private only while it is switched on, the opposite of Film Original (PDLC).
What happens when the power goes off?
The glass stays clear, so the space keeps its view and daylight during a power outage.
Can it be applied to glass I already have?
Yes. PriWatt™ film is a self-adhesive film applied directly to existing interior glass, windows and doors, so the glass does not have to be replaced.
How fast does it switch?
Under 200 milliseconds from clear to private and under 10 milliseconds back to clear, so the change looks instant.
Does privacy mode block the view completely?
In privacy mode haze reaches 94%, so people and shapes cannot be made out while natural light still comes through. It is a privacy product, not a blackout blind.
What colors are available?
Film Reverse is available in white only.
How is it controlled?
With a wall switch, a remote, a smartphone, or through Alexa and Google Home. Panels can be grouped and scheduled.
Can I install it myself?
We do not recommend it. Our certified installers measure and apply the film, and a certified electrician makes the power connection. Busbar positions and wiring have to be planned before manufacturing.
Can Smart Film be applied to glass I already have?
Yes. PriWatt™ film is a self-adhesive PDLC film applied directly to existing interior or exterior glass, windows and doors, so the glass does not have to be replaced.
What happens when the power goes off?
Film Original turns private when the power is off and still lets about 73% of daylight into the room. Film Reverse does the opposite and stays clear when unpowered.
How fast does it switch?
Under 45 milliseconds from private to clear and under 10 milliseconds from clear to private, so the change looks instant.
Does privacy mode block the view completely?
In privacy mode haze reaches 95%, so people and shapes cannot be made out while natural light still comes through. It is a privacy product, not a blackout blind.
Can I install it myself?
We do not recommend it. Our certified installers inspect the project, take precise measurements and apply the film, and a certified electrician makes the power connection. Busbar positions and wiring have to be planned before manufacturing.
How do I clean it?
Switch the film off, wipe with a soft cloth and 99% isopropyl alcohol, and make sure no liquid is left sitting on the edges.
How is it controlled?
With a wall switch, a remote, a smartphone, or through Alexa and Google Home. Panels can be grouped and scheduled.
How long does it last and what is covered?
The film is rated for 2 million switching cycles and a life cycle over 15 years, and it comes with a 2-year limited warranty.
Both are laminated switchable glass panels that change between clear and private. The difference is what the glass does when the power is off — and that decides which one fits your space.

Reverse Glass uses PNLC technology, so it is clear when power is off and turns opaque when power is on. Standard PDLC glass works in the opposite way.
Is Reverse Glass a good choice for offices?
Yes. It is ideal for meeting rooms and interior partitions where glass normally stays clear and privacy is needed only at selected times.
Does it provide privacy during a power outage?
No. Reverse Glass becomes clear when power is off. For fail-private applications, standard PDLC glass is usually the better choice.
How quickly does it switch?
The glass turns private in under 200 milliseconds and returns to clear in under 10 milliseconds.
Is it energy efficient?
Yes. It runs on 25–80 VAC low voltage and consumes less than 0.5 watts per square foot while powered — and it needs no power at all to stay clear.
Can it be used in doors and partitions?
Yes. The laminated construction makes it suitable for interior doors, office partitions, conference rooms and other architectural glazing applications.
What colors are available?
Reverse Glass is available in white only. Grey and tinted options are offered on standard PDLC glass.
Where can I find installation information?
The technical manual above includes handling, electrical and installation guidance. A qualified glazing professional should complete installation.

It is laminated architectural glass with a PDLC liquid crystal film bonded inside the lamination. It is manufactured as a finished safety glass panel, in low iron, heat strengthened or tempered builds.
What happens when the power goes off?
Glass Original turns private when the power is off and still lets about 73% of daylight into the room. Glass Reverse does the opposite and stays clear when unpowered.
How fast does it switch?

In privacy mode haze reaches 95%, so people and shapes cannot be made out while natural light still comes through. It is a privacy product, not a blackout blind.
How large can a panel be?
Up to 70″ × 144″ at 9/16″ thickness and 70″ × 126″ at 1/2″. Larger areas are built from several panels, and curved shapes, holes and cut-outs are possible.
Can it be used outside and in doors?
Yes. For exterior use the panels are built into insulated glass units, and doors are glazed with the wiring routed through the frame or hinge. The wiring route has to be planned before manufacturing.
Who installs it?
A certified glazier installs the glass and a certified electrician makes the power connection. Our project managers handle measurements, manufacturing and coordination.
How long does it last and what is covered?
The glass is rated for 2 million switching cycles and a life cycle over 15 years, and it comes with a limited warranty. Working temperature range is -22°F to 122°F.
