PPG has developed a technology for aircraft windows that is claimed to “significantly” block harmful ultraviolet (UV) radiation and high-energy visible (HEV) light to help protect aircrews, passengers and aircraft interiors from solar radiation. According to PPG, cockpit and cabin windows treated with its Solaron Blue Protection UV+ blocking technology during manufacture block 99% of UVA and UVB radiation and more than 50% of HEV (blue) light.
“UV radiation exposure increases about 11% for every 3,300ft (1,006m) increase in altitude,” said Brent Wright, PPG’s global director for aerospace transparencies. “At flight altitudes for jet aircraft, the radiation threat is approximately three times the exposure at sea level. PPG windows with PPG Solaron Blue Protection UV+ blocking technology help protect people and interior aircraft components from harmful radiation without the optical, structural and other window properties being affected.”

Paris Air Show visitors can see a flight-deck window for an Airbus A320 Family jetliner with PPG’s UV+ blocking technology at Hall 2b Stand F94 on June 17-23 at Le Bourget.
