Switchable Glass

*Please note: This product is currently available to UK customers only

Contra Vision® Switchable Glass™ offers instant (less than 1 second) privacy, transitioning from transparent to opaque at a press of a button.

Contra Vision Switchable Glass works by applying a small electric current to a liquid crystal center, which causes the liquid crystals to align in such a way that when switched on, light is able to pass through the glass, and thus gives clear through-vision form both inside and outside.

When the glass is switched off, the liquid crystal layer is no longer aligned, making the glass opaque to provide privacy when you need it, for both inside and outside, without the need for blinds or curtains.

Contra Vision also offers the option of Switchable Film. This film works by the same principles as switchable glass, but it has a self-adhesive cling layer on one side and is dry applied so it can be retrofitted to existing glass, or transparent surfaces with ease.

The Switchable Film is also very easy to maintain and clean by using low pressure compressed air, and a soft bristled cleaning/dusting brush. Soft IPA wipes can also be used.

Our Switchable Film is available in two standard width sizes – 1000mm (38.6”) and 1200mm (47.3”). For larger areas, multiple sheets can be joined together. The films can be cut to any size at the factory, custom shapes and sizes are also available.

Our Switchable Glass is available in a range of sizes, thicknesses, and as single, double or triple glazing.

Contra Vision Switchable Glass, when switched off (opaque), provides a white surface perfect for projecting. This could be used for functional purposes, such as presentations, advertising, or displaying videos and games, or for more decorative purposes.
