PPG Shows Darker Side of Dimmable Window

Passengers on business jets will be able to block more light coming through electrically dimmable cabin windows with a new dual-panel option from PPG Industries’ aerospace transparencies group. The Alteos Interactive Window Systems brand, based on Gentex electro-chromic technology, allows passengers to
control the amount of light coming through windows, switching from a bright, clear state to an opaque state and intermediate levels. The standard system uses dual electro-chromic panels of gel installed between the inboard dust cover and the outboard structural cabin window. The amount of electrical current passing through the panels determines their level of clarity. The original Alteos system is certified on the Hawker Beechcraft King Air 350i, and Boeing has selected the system for its new 787 Dreamliner.
