PPG has developed technology for aircraft windows that significantly blocks harmful ultraviolet (UV) radiation and high-energy visible (HEV) light to help protect aircrews, passengers and aircraft interiors from solar radiation.
According to the company, PPG windows with PPG Solaron Blue Protection UV+ blocking technology block 99% of UVA and UVB radiation and more than 50% of HEV (blue) light. The new technology will be showcased at the Paris Air Show.
“UV radiation exposure increases about 11% for every 3,300-foot (1,006-meter) increase in altitude,” said Brent Wright, PPG global director, 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.”
While current aircraft windows already block some solar radiation, windows incorporating PPG Solaron Blue Protection UV+ blocking technology will offer a higher level of protection across a broader range of threats. The new technology is incorporated into PPG’s windows at the time of manufacture and can be applied to cockpit and cabin windows.
“PPG windows with PPG Solaron Blue Protection UV+ blocking technology offer comprehensive protection in the most threatening part of the UV and blue light portions of the light spectrum,” said Wright. “In aircraft equipped with windows featuring the new technology, flight crews and passengers are afforded enhanced protection inside the cockpit and cabin with no sacrifice to their outside view.”
