PPG Aerospace NBAA Display Shows Gold, Silver Solar-reflective Window Coatings
Transparencies with neutral-silver and gold coatings have similar solar-reflective performance, with lower infrared transmittance than uncoated transparencies so interior cockpit and cabin temperatures are easier to keep comfortable, he said.
PPG tests have shown solar transmittance for a stretched-acrylic cabin window with its neutral-silver solar-reflective coating to be about half that of an uncoated window while maintaining high visible light transmittance. Also, the neutral look of the silver coating coordinates well with the neutral appearance of Alteos window systems, enhancing aesthetics when viewed from the interior of the aircraft.
PPG expects to qualify solar-reflective-coated stretched-acrylic passenger-cabin windows this year with a major airframe manufacturer, Stone added. PPG also will develop glass cockpit windows with solar-reflective coatings, he said.
