PPG Aerospace is a leading and experienced manufacturer of original-equipment and replacement windshields and side cockpit windows for Embraer airplanes. PPG Aerospace has been the single source of cockpit windows to Embraer and worldwide operators of the Embraer E170/E175/E190/E195 regional jet fleet since the first aircraft was delivered.
PPG's continuous improvement of the windshields has provided the industry with transparencies that are among the longest performing and most reliable. The all glass design for the windshields features chemically strengthened glass, advanced urethane technology, and ant-ice/anti-fog coatings. The all glass design is based on Herculite® II chemically strengthened glass developed by PPG. The outstanding properties of Herculite® II allow designers to meet the challenging operating envelope for Embraer E170/E175/E190/E195 aircraft.
Herculite® II is used in transparency systems where designs require high strength to weight ratio, high performance, and long service life. Additionally, it offers greater damage tolerance and scratch resistance as a result of its high surface hardness. The unique properties of Herculite® II chemically strengthened glass allow lightweight cockpit windows to be designed for structural, load bearing applications. For these applications, aircraft loads are transferred through the cockpit window, thus allowing for reduced weight in the fuselage structure.
Since its introduction, Herculite® II chemically strengthened glass has been field proven in all cockpit window applications for both structural and nonstructural applications. Herculite® II is used on other commercial, general aviation,
