What is this advanced glass technology that lets you instantly switch glass from transparent to opaque? It’s called switchable glass, and it brings much-needed adaptability, privacy, and energy efficiency to any space.
As building technologies continue pushing the envelope, switchable glass emerges as one of the most exciting and futuristic advances for commercial and residential settings alike. Keep reading to discover everything you need to know about this innovative class of smart glass in 2024.
What is Switchable Glass and Smart Glass Technology?
Switchable glass suits modern design demands thanks to special liquid crystals or suspended particles embedded within glass or film layers. Applying a low-voltage charge triggers these particles to align in a uniform direction.
This polarization process transforms transparent glass into an opaque, frosted, or dimmed state. Cutting electricity returns particles into a random orientation, so the glass looks perfectly clear again.
Such incredible versatility gives users manual control over privacy, sunlight, heat, and even digital displays projected onto switchable glass surfaces. No wonder architects, automakers, and homeowners increasingly specify switchable glass in their designs!
Switchable glass falls into an exciting new category called smart glass technologies encompassing things like:
  • Switchable privacy glass - Provides privacy control via transparency and opacity
  • Switchable smart glass - Changes states with electricity for shading and displays
  • Glasses with switchable frames - Eyewear lenses that transition with ambient light
While photochromic and thermochromic glasses harness passive environmental triggers, active switchable glass requires applied electricity to transform states. This guide focuses specifically on the actively controlled types.
How Does Switchable Glass Work?
Switchable glass relies on ingeniously engineered films layered between glass panels. Applying voltage to these switchable interlayers makes embedded particles shift orientation from scattered to aligned.
This uniform polarization prevents light passage, turning clear materials opaque. Cutting electricity returns particles into random directions, restoring full transparency.
Currently, three types of electrically switchable interlayers exist:
  • PDLC - Polymer-dispersed liquid crystals
  • SPD - Suspended particle devices
  • ECD - Electrochromic devices
Of these options, PDLC and SPD films offer the fastest transitions, capable of shifting glass walls from opaque to clear in seconds. Meanwhile, electrochromic technology changes more gradually, with transitions spanning several minutes.
While these smart glass films share similar polarization principles, their particle ingredients and applications differ:
PDLC Smart Glass
The most common switchable glass interlayer contains liquid crystal formulations dispersed within durable polymer. Applying low voltage to PDLC glass aligns the fluid crystals, blocking visible light transmission.
Benefits:
  • Millisecond transition speeds
  • Widely available
  • Visible light control
  • Privacy capabilities
  • Good clarity (2.5% haze rating)
Applications:
  • Interior partitions
  • Projection surfaces
  • Display cases
  • Conference rooms
SPD Smart Glass
SPD technology suspends microscopic rod-like particles in liquid between conductive coatings. Electricity aligns the suspended particles, blocking or dimming incoming light.
Benefits:
  • Millisecond transitions
  • Dynamic daylight control
  • Up to 99% light blockage
Applications:
  • Skylights
  • Windows
  • Sunroofs
  • Partitions
Electrochromic (EC) Smart Glass
Also known as smart tint, electrochromic glass contains special ions that shift between conductive layers when electrically triggered. As ions relocate, the glass transitions gradually from clear to tinted.
Benefits:
  • UV and infrared light control
  • Preserves some visibility when tinted
Applications:
  • Building windows
  • Skylights
  • Curtain walls
While electrochromic transitions happen slowly compared to PDLC and SPD films, the technology provides superior shading capabilities.
Now that you understand the core switchable glass technologies, let’s explore some amazing benefits they offer.
5 Incredible Benefits of Switchable Glass
Beyond the “wow” effect of instantly transforming transparent glass into an opaque surface, switchable glass technologies yield practical perks spanning aesthetic, functional, and sustainability domains.
1. On-Demand Privacy
Switchable glass allows users to electronically toggle transparent partitions, walls, or windows between open visibility and obscured opacity. This enhances privacy while maintaining inbound daylight when desired.
Installing switchable glass means no longer needing traditional curtains, shades, or blinds to achieve privacy. Minimalist contemporary spaces remain clean, neat, and visually uncluttered with switchable glass.
2. User-Controlled Shading
While manual window coverings might inadequately address intense daylight or glare issues, switchable glass technologies like SPD smart windows finely control incoming light levels.
With the ability to select anything from fully blocked to partially tinted states, switchable glass puts personalized shading and daylighting at occupants’ fingertips.
3. Energy Savings
In their transparent setting, switchable glass windows minimize interface reflections, allowing full visible light and solar heat gain entry. However, the switchable particles also reflect or absorb infrared and ultraviolet rays when aligned.
This solar control ability helps minimize heat buildup inside buildings. When opaque, switchable glass acts almost like insulation, further cutting air conditioning demands in warm weather.
Studies by the American Society of Heating, Refrigerating and Air-Conditioning Engineers found switchable glass facades can reduce building cooling loads by 10 to 15%.
4. Interactive Displays
Switchable glass paired with projection technology transforms walls, partitions, and even elevator interiors into dynamic display surfaces.
For example,transparent switchable glass installations become opaque projection screens with the flip of a switch. Power down projection equipment again, and the glass returns to see-through clarity.
Such interactivity creates immersive environments for advertising, entertainment, communications, and educational settings. Projected elements come alive on switchable glass in ways static signs or monitors cannot achieve.
5. Safety and Security
Compared to conventional glass, switchable smart glass enhances safety and security. Instead of breaking into dangerous shards, switchable interlayers help keep glass fragments somewhat adhered even when severely cracked.
Switchable opacity also functions as an electronic security barrier protecting interiors from unwanted viewing. Facilities managers regain control over visibility, unlike traditional glazing allowing unobstructed exterior lines of sight.
These five benefits represent just a sampling of the value switchable glass adds wherever it gets incorporated!
Next, let’s survey some premiere settings taking advantage of switchable technology today.
Top 5 Places Using Switchable Glass
Many forward-thinking buildings highlight switchable glass capabilities, but these five project types truly showcase the technology’s versatility:
1. Partition Walls
Open floorplans keep gaining popularity in office spaces, demanding flexible room dividers. Switchable glass partitions beautifully adapt based on evolving privacy, collaboration, and space needs.
For example, a clear glass conference room readily transforms into an opaque projection theater, then switches back to visibility afterward. No more need for makeshift projector screens or closing blinds!
2. Hospital Rooms
Hospitals increasingly turn to switchable glass instead of curtains around patient beds. Switchable privacy maintains essential patient confidentiality while improving hygiene and aesthetics.
Nurses and doctors electronically switch glass walls or windows between transparent and opaque states as needed for patient care, family visits, and medical procedures.
3. Home Windows
Residences also tap switchable glass technologies, using smart tinting on windows, doors, room dividers, and skylights. This saves energy by blocking solar heat gain in summer without sacrificing views. It also affords privacy control.
Rather than closing drapes or shades on hot sunny days, homeowners simply use controls to switch glass to darker tints. Powering down returns windows to full clarity.
4. Retail Displays
Creative retailers transform entire storefronts into transparent projection screens using switchable glass. Powerful marketing visuals blanket glass exteriors when opaque, then windows seamlessly revert to clear, showcasing merchandise.
Adidas pioneered such techniques in new flagship stores. Their Futurecraft Lab incorporates floor-to-ceiling switchable glass allowing both rear projection shows and inside views.
5. Trains and Automobiles
Switchable glass keeps gaining traction within transportation industries eager to balance privacy needs with daylighting. Auto sunroofs, privacy partitions, elevators, and trains employ smart glass.
For example, Japanese higher-speed rail services feature switchable glass separating passengers from engineers. With the flip of a switch, glass walls shift from transparent to opaque and back again.
