PPG Aerospace: Onboard with Boeing's Dreamliner 787

Passengers aboard the new Boeing 787 Dreamliner will be able to darken or lighten their windows at the touch of a button for more comfortable travel. Global aircraft window leader PPG Aerospace has been awarded a contract by the Boeing Company to supply electronically dimmable systems for the windows of the 787 passenger compartment. The passenger-cabin windows on the Boeing 787 will be almost 25 percent larger than those on the Boeing 777 and will allow passengers to adjust the amount of light transmitted to five different levels from dark to clear. The new window systems will not only provide light control, but also enhance the interior appearance and comfort of the aircraft. Electrochromic technology uses electricity to darken an electrically conductive medium between two layers of glass. Turning off the electricity bleaches, or lightens, the medium.
