Reveal, Guardian

An electric current renders this glass opaque or transparent at the user's command.


Offering daylighting potential and the option for privacy when needed, Guardian’s Reveal is suitable for healthcare, office, hospitality, and retail spaces. The glass changes from transparent to opaque when triggered by a switch, motion detector, or daylight sensor. The glass is laminated with a liquid crystal film and a polyvinyl butyral interlayer that remain opaque until rendered transparent by an electric current. guardianglass.com
