PPG Aerospace Awarded Boeing Contract For Electrochromic Cabin Window Systems

HUNTSVILLE, Ala., Dec. 15, 2005 – 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’s passenger compartment.

“Bringing innovation to the marketplace is a core strength at PPG, which is why the aerospace industry is so important to our company,” said Charles E. Bunch, chairman and chief executive officer of PPG Industries.

“Aircraft manufacturers and their customers are continually seeking opportunities to improve performance, and we’re delighted to help them meet their technology requirements.”
According to David Morris, PPG Aerospace vice president, the Boeing 787 will be the first commercial aviation application for electrochromic window technology.

“We are excited about providing Boeing the latest innovation in the transparencies world that promises to revolutionize air travel on its new Dreamliner,” Morris said.

“PPG has explored variable-transmittance window technology for aircraft over several years. The culmination of this effort is our involvement in the 787 Dreamliner. Together we are meeting the needs of the public for more enjoyable travel and helping airlines enhance their operating efficiency. We are especially pleased that we will be introducing a new type of window component on such a technologically advanced airplane as the 787.”

Expected revenue is about $50 million over the first five years, according to Morris.

Under a separate related agreement, PPG Aerospace and Gentex Corporation, the Zeeland, Mich.-based manufacturer of automatic-dimming rearview mirrors and commercial fire protection products, will work together to produce the variably dimmable electrochromic cabin window systems for the Boeing 787.

Morris said that the PPG-Gentex relationship capitalizes on the individual strengths of two industry leaders in order to create and commercialize the new technology at a faster pace than either could do alone.

“PPG brings its unmatched aircraft transparency expertise to Boeing as well as the world’s airlines,” Morris said.

“We have the knowledge and systems in place to successfully supply the electrochromic transparencies. Importantly, we understand the requirements for a transparency operating in an aircraft environment in order to be qualified. In addition, we have the infrastructure and experience needed to provide airlines with direct worldwide product support and sales service in the aftermarket.”

Gentex brings its patented electrochromic technology, as well as expertise in electronics and microelectronics, that will be utilized in the window panels and control systems, according to Garth Deur, Gentex executive vice president.

“This is a start for Gentex, in a new industry, and offers us the ability to leverage some of the research and development dollars we have invested over the years in the development of this unique variably dimming technology.”

Electrochromic panel prototypes will be provided to Boeing in early 2006, and first production units for evaluation are due by mid-2006. First articles are expected to be produced for flight evaluation by the fourth quarter of 2006, according to Morris. Volume shipments are expected to begin in mid- to late 2007.

The passenger-cabin windows on the Boeing 787 will be almost 25 percent larger than those on the Boeing 777, Morris noted.

The electrochromic transparencies will allow passengers to adjust the amount of light transmitted to five different levels from dark to clear, with a manual override for use by the flight crew. The dimmable window panels will be inserted between the exterior cabin window and interior plastic dust cover.

Morris noted that the new window systems will not only provide light control, but also enhance the interior appearance and comfort of the aircraft.

“Passengers will be able to control the amount of solar energy that enters the cabin to reduce solar light and heat transmittance for more comfort, and there will be less stress on the heating and air conditioning system,” Morris said. “Because there will be no window shades, interior space will be more attractive.”

Electrochromic technology uses electricity to darken an electrically conductive medium between two layers of glass. Turning off the electricity bleaches, or lightens, the medium.
