Smart Glass with PDLC: Frequently Asked Questions

Interested in Smart Glass but have some questions? Or, better yet, you don’t even know what to ask?

We’re here to help. 

We’ve compiled a list of the most common questions to help you better understand switchable smart glass, specifically one of the most commonly used technologies used for smart glass and smart film: PDLC (Polymer Dispersed Liquid Crystal). 

What are other names for smart glass?
Switchable glass, switchable film, PDLC film, privacy glass, dimmable glass, electronically controlled windows, LCG® (light control glass), Liquid Crystal Glass, switchable windows.

What is Smart Glass?
Smart glass is the general name for glass or other transparent materials, that change opacity from transparent to translucent or opaque to block different types of light. 

What Are The Different PDLC Glass Applications? 

• Smart glass for Offices: conference rooms, private offices, work pods, confidential areas 
• SPD for Autos: advertising on windows, temperature control, privacy
• Hotel Smart Glass: bathroom enclosures, dynamic lobbies, stores, restaurants 
• Retail Smart Glass: polite advertising on store fronts, dressing rooms, concept spaces
• Healthcare Smart Glass: private patient rooms, operating rooms, ICU areas.
• And more!

Why is PDLC called Privacy Glass?
When switched off, liquid crystal films are opaque, or solid, and can be used to make a space private.

Can you project on PDLC?
Yes! PDLC creates the best projection surface with HD quality visuals and 180° viewing angles, turning switchable glass into a liquid crystal display. The best part? It can turn transparent for full use of windows or glass partitions instantly. 

What is the difference between Laminated and RetroFit PDLC Smart Film?
Laminated films are handled by glass fabricators and laminated between two pieces of glass with interlayers like PVB, EVA, or TPU. RetroFit PDLC films are applied to an existing piece of glass by window film installers.

What frame types does LC Smart Glass require?
LC Smart Glass is compatible with most types of internal partition systems including sliding panels, IGU partitions and windows, and U or T profiles from most materials.

How long does it take PDLC smart glass to switch?
Pretty fast – less than .1 second to be exact! 

Are there different types of PDLC smart films?
Depending on the manufacturer, PDLC can be made in various colors, with patterns or temperature control formulations that increase green points in buildings. 

How do you clean switchable glass?
Just like any other glass — with a soft cloth and window cleaner. 

Is PDLC smart film suitable for indoor or outdoor use?
PDLC glass is typically used for indoor applications, but some companies have outdoor grade technologies. Learn more about outdoor grade PDLC film.

Can switchable smart glass replace blinds and shades?
PDLC can replace blinds or shades used to create privacy in interiors. PDLC Smart Glass with IR reflection capabilities can also help control temperature. SPD is used to block up to 99% of light, creating shade, making it ideal for exterior windows. 

How much power does switchable smart glass consume?
LC smart glass consumes 3 watts per sqm. For perspective: 10sqm of PDLC switchable glass consumes less energy than one LED bulb 

What does smart glass cost?

• Off-the-shelf switches like Lutron or Gauzy’s touch panels
• Smart home or office systems 
• Alexa or other voice activation platforms 
• Sensors 
• Radio remote controllers
