Laminated Privacy Glass is Switchable

Liquid Crystal Switchable Privacy Glass from Innovative Glass Corp. is laminated glass that has an electrified film embedded within the glass. It can be switched from clear to frosted white with the flick of a switch. In the unpowered, default state, the glass is completely obscure, providing 100 percent privacy from both sides and,  although private, light still passes through. With electricity, the molecules in the film reorient and the glass instantly becomes clear. The glass has no moving parts, is virtually soundproof and can be tempered, making it almost indestructible. This glass can be installed in fixed walls, partitions and sliding walls, as well as in swinging and sliding/breakaway doors. Retrofit Magazine
