Reverse PNLC Film
The logic, reversed. PNLC film is crystal clear when power is off and switches opaque only when energized — fail-clear privacy that stays transparent during a power outage.
Clear by default, private on demand
Standard PDLC film is opaque when off and clear when on. Reverse PNLC (Polymer Network Liquid Crystal) film flips that behavior: it is transparent with no power and turns opaque only while energized.
That makes it ideal anywhere the glass should be clear most of the time — and where you want it to fail to clear during a power interruption, such as escape routes, retail and feature glazing that is private only on demand.
- Clear when OFF, opaque when ON (reverse of standard)
- Fail-clear: defaults to transparent on power loss
- Energy-smart for glass that stays clear most of the day
- Same instant switching and certified construction
Why choose reverse film
Reversed Logic
Transparent at rest, opaque only when you power it on.
Fail-Clear Safe
Defaults to clear on power loss — useful for egress and visibility.
Energy-Smart
Draws no power in its everyday clear state for glass that is rarely private.
Instant Switch
Switches private in under a second when energized.
Made to Measure
Cut to size for windows, partitions and feature glazing.
Certified
ETL Certified and UL compliant, manufactured in the USA.

Reverse PNLC FAQ
What is the difference between PDLC and PNLC?
Standard PDLC film is opaque when off and clear when powered. Reverse PNLC film is the opposite — clear when off and opaque only when powered. Choose PNLC when the glass should be clear by default.
Why would I want fail-clear behavior?
If the power fails, reverse film returns to clear rather than opaque. That is desirable for egress routes, security visibility and any space that should not be blacked out during an outage.
Is it more energy efficient?
For glass that stays clear most of the time, yes — it uses no power in its default clear state and only draws power during the moments you need privacy.
