Laminated Privacy Glass is Switchable

Electrified film is embedded within the glass

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 transparent to frosted white with the flip of a switch. In the unpowered, default state, the glass is completely obscure, providing 100% privacy from both sides. When in the private state, light still passes through. With electricity, the molecules in the film reorient and the glass instantly becomes transparent. The glass 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 and breakaway doors. Retrofit Magazine
