Question 1

What is CLiC?

Accepted Answer

CLiC is a powered switchable privacy glass that offers homeowners, window manufacturers, builders, designers, and architects an exciting new technology for creating privacy. CLiC combines the most advanced liquid crystal science with Cardinal’s proven expertise in glass manufacturing and fabrication. When it comes to privacy, clarity, switching speed and durability, CLiC stands alone.

Question 2

Where Can I Install CLiC Glass?

Accepted Answer

CLiC can be installed in virtually any interior glazing application where standard insulating glass is used. Common residential applications include bathroom windows and shower enclosures, bedroom and nursery privacy partitions, home office dividers, and patio doors. Commercial installations include conference rooms and executive offices, healthcare patient rooms and exam areas, storefront displays, and hospitality environments. CLiC is designed for interior use and is available as an insulating glass (IG) unit that fits into standard window and door frames.

Question 3

How Does CLiC Create Privacy?

Accepted Answer

CLiC uses polymer-dispersed liquid crystal (PDLC) technology. When electrical current is applied, the liquid crystals align to allow light to pass through clearly, making the glass transparent. When the power is turned off, the liquid crystals scatter into random orientations, diffusing light and creating a translucent, frosted appearance. This transition happens almost instantly and provides full visual privacy while still transmitting natural daylight into the space.

Question 4

Does the CLiC Unit Reduce Light Transmittance?

Accepted Answer

In the clear (powered-on) state, CLiC allows a high level of visible light transmittance comparable to standard insulating glass. In the private (powered-off) state, CLiC still transmits a significant amount of diffused natural light into the room, maintaining a bright and comfortable environment even when privacy is engaged. The exact transmittance values depend on the glass configuration and coatings selected.

Question 5

What Is the Maximum and Minimum Size?

Accepted Answer

CLiC is available in a wide range of sizes to accommodate most architectural glazing needs. The minimum size is approximately 12 inches by 12 inches (305 mm x 305 mm). The maximum size can reach up to approximately 45 square feet per panel, depending on the specific configuration. Contact CLiC for exact sizing requirements for your project, as custom dimensions are available to fit non-standard openings.

Question 6

What Is the Overall Thickness of CLiC?

Accepted Answer

The overall thickness of a CLiC insulating glass unit is comparable to a standard IG unit. The switchable laminate layer adds minimal thickness to the overall assembly. Typical configurations range from approximately 3/4 inch to 1 inch (19 mm to 25 mm) overall, making CLiC compatible with standard window and door frame systems without requiring special framing modifications.

Question 7

How Fast Does CLiC Switch?

Accepted Answer

CLiC switches between clear and private states in under one second. The transition from private to clear is nearly instantaneous when power is applied. The transition from clear to private when power is removed is equally rapid. This fast switching speed allows for responsive control of privacy in any setting.

Question 8

How Well Does CLiC Provide Acoustical Privacy?

Accepted Answer

CLiC insulating glass units provide sound attenuation comparable to or better than standard insulating glass. The laminated construction of the switchable layer adds mass and damping that can improve acoustical performance. For applications requiring enhanced sound control, CLiC can be specified with additional acoustic interlayers or thicker glass panes to meet specific STC (Sound Transmission Class) requirements.

Question 9

How Is CLiC Controlled?

Accepted Answer

CLiC can be controlled through multiple methods to suit different installation requirements. Options include wall-mounted switches, wireless remote controls, building automation system integration, smart home platforms, and timer-based scheduling. Multiple CLiC panels can be controlled individually or grouped together for zone control. The low-voltage power system makes integration with existing building controls straightforward.

Question 10

What Happens If the CLiC Unit Loses Power?

Accepted Answer

If power is interrupted, CLiC defaults to the private (translucent) state. This fail-safe design ensures that privacy is maintained during power outages. The glass will automatically return to the clear state once power is restored. This default-to-private behavior is a built-in safety feature that is especially valuable in healthcare, hospitality, and residential privacy applications.

Question 11

How Much Power Does CLiC Use?

Accepted Answer

CLiC is extremely energy-efficient, consuming approximately 5 watts per square meter in the clear (powered-on) state. This is comparable to the energy consumption of a small LED light. In the private state, CLiC consumes zero power since it requires no electricity to maintain the translucent condition. The low power consumption makes CLiC a cost-effective privacy solution with negligible impact on energy bills.

Question 12

How Do I Maintain the CLiC Unit?

Accepted Answer

CLiC requires no special maintenance beyond standard glass cleaning. Clean the glass surfaces with a mild, non-abrasive glass cleaner and a soft cloth, just as you would any other window. Avoid using harsh chemicals, abrasive pads, or razor blades on the glass surface. The electrical connections should be inspected periodically by a qualified electrician as part of routine building maintenance.

Question 13

Is the Liquid Crystal Safe?

Accepted Answer

Yes, the liquid crystal material used in CLiC is completely safe. It is permanently sealed between two layers of glass in a laminated construction, so there is no exposure to occupants under normal use. The materials meet all applicable safety standards for building products. In the unlikely event of glass breakage, the laminated construction holds the glass fragments together, similar to automotive safety glass, preventing dangerous shards from separating.

Question 14

Who Is Cardinal Glass Industries?

Accepted Answer

Cardinal Glass Industries is one of the largest glass fabricators in North America, with over 40 years of experience manufacturing high-performance residential and commercial glass products. Cardinal operates multiple manufacturing facilities across the United States and is known for its advanced glass coating technologies, including Low-E glass products. CLiC is developed and manufactured by Cardinal IG Company, leveraging Cardinal's deep expertise in insulating glass fabrication and quality control.
