TENA 14.5mm switchable glass (also called privacy glass, smart glass, PDLC glass, magic glass, etc.)


& scientific principle

TENA switchable glass is composed of layers of glass sheets & interlayer films, with an electric switcher and a remote cotrol. The core film (PDLC-Polymer Dispersed Liquid Crystal) has the property of “switchable color-changing”, that is, when the power is on, the glass is transparent; but when the power off, it turns to be opaque immediately. (As shown below by the photos).

Wide applications

The property of “switchable color-changing” can be used to protect the privacy of users if necessary, and keep the glass transparent when there is no need to do so. TENA switchable glass has a wide range of applications below:

Residential buildings, such as bathrooms, room partitions/windows, windows in balcony, cinema curtain, etc.

Office buildings, such as room partitions/windows, windows in balcony, project curtain in meeting room, etc.

Hospitals, to act as partitions or curtains, or windows.

Banks, jewelry shops, museums, etc.

Other buildings suitable for such a special feature.


The outer glass sheets can adopt TENA tempered glass instead of common glass. Thus TENA switchable glass can protect both privacy and safety of users as the tempered glass is a kind of very strong safety glass with features below.

Superior safety: In case of being broken, TENA tempered glass sheet will change into thousands of tiny pieces without acute angles. Thus no injuries to the body of human beings can be caused.

High-impact performance: TENA tempered glass can withstand the vertical hit of a 1 Kg steel ball falling freely from 1 meter height, and separately, the side hit by a 45 Kg ball of lead bullets from 1.2 meter height, without broken. Its performance is 5~10 times higher than that of ordinary flat glass sheets.

Better heat-stability: It can stand a heat-shock (sudden change of temperature) of 220~250 °C, while a common glass sheet of the same thickness can only stand 70~100 °C.

Building projects applied

TENA products have been widely used successfully in hundreds of outstanding buildings, such as National Center for the Performing Arts (NCPA) in Beijing, Guangzhou International Finance Centre (IFC), Guangzhou Railway Station, 5-star Sheraton Dameisha Resort Hotel Shenzhen,etc. TENA products are welcomed by more and more clients.
