What is UCEF Switchable Privacy Glass and how does it work?

UCEF Switchable Privacy Glass is produced by laminatingpolymer-dispersed liquid crystal film with architectural grade EVA between twolayers of customer-specified glass. The glass can transform from acloudy-white, translucent barrier to an optically clear state with the flick ofa switch.

Is the glass transparent with the power ON or OFF? Can it be reversed?

The glass is transparent when the power is ON. No, themechanism cannot be reversed.

Can the Switchable Privacy Film be ordered separately without the glass?

Yes, with limited warranty.

What is laminated glass?

Laminated glass consists of two panes of glass adheredtogether with by an interlayer, typically EVA, and is considered safety glass.The interlayer holds the entire piece together if the glass ever gets broken sothere will be no holes, large or sharp shards.

What are the various glass types?

Annealed, tempered, heat- and chemical-strengthened.

What is the difference between laminated and toughened glass and whichshould I use?

UCEF privacy glass is considered a laminated glass orsafety glass, which means that the risk of injury is minimal because it breaksinto small, dull shards. Toughened glass that is not laminated has a higherrisk of injury because it has the potential to break into large, sharp shards.What type of glass one would use depends on the application.

 

How is UCEF priced and what is the cost?

It is priced in square-meter (sq. m.). Cost variesdepending on the design and the glass type.

What is the operational voltage?

60VAC, provided with our transformer.

What are the available glass colors?

Clear, gray and dark grey tint.

Is it energy efficient?

Yes, the electric consumption is less than 5W/sq.m.

Can multiple glass panels be connected together?

Yes, glass panels need to be connected in parallel.

Does it come in any other shapes?

Custom shapes and sizing are available at no additionalcost.

What is the percent transmission (%VLT) of the glass?

The transmission in the clear state is approximately 75%when viewed straight on.

Are there any requirements regarding the framing (aluminum ornon-aluminum) ?

No, any frame would be suitable.

What is in a typical order package?

The UCEF privacy glass, 60 VAC transformer, siliconesealant if needed.

What types of professionals are required for the electrical and glassinstallations?

Certified electricians and glaziers are required.

How much shipping time should be allocated domestically andinternationally?

Usually within 1 week domestically. Shipping times tendto vary more internationally.

Where are the busbar and wires used to power the film located?

Busbars are located at the long or short edges of thefilm. Please contact us for configuration options.

Can UCEF glass panels be butt-joint?

Yes, but ONLY with other UCEF panels.

Why is UCEF not as clear as regular glass?

It contains liquid crystal materials that opticallymanipulate light; therefore, it will naturally have some level of haziness toit. This haziness effect is magnified at larger viewing angles and with certainhigh-intensity lighting conditions.

What type of silicone to be used?

Neutral cure silicone ONLY.

Does the UCEF privacy glass have a remote control?

No, but a remote control can be used.

What is the lifetime of the UCEF privacy glass?

Indoor use lasts 10 years or more.

Can logos or patterns be etched into the UCEF privacy glass?

Yes.

Can the wires attached to the glass support the weight of the glass?

The wires are for powering the glass and cannot handlethe stress, which means you cannot pull on the wires to move it or use it tohang the glass. For mounting purposes, you will need to utilize a frame orallow us to drill holes into the glass.

Can the wire leads be connected to only one point of the glass?

No. Typically wire leads are connected at 2 corners ofthe glass.

What is the viewing angle?

Approximately 150o. Which means thetransmission will be reduced to less than half when viewed at a

75 o degree angle.

What is the operating temperature range?

–30oC to 60oC (-20oF to140oF).
