Glass makes view from the top possible

Towering above the Chicago skyline at 1,450 feet, Willis Tower (formerly the Sears Tower) is the tallest building in North America. Its newest feature, the "Skydeck Ledge," features all-glass viewing booths that provide a heart-pounding, but safe, view thanks to DuPont SafetyGlas structural interlayers. The deck construction, laminated with DuPont SentryGlas, is 1½ inches thick, offering five times greater strength and 100 times greater stiffness than conventional laminating interlayer materials. It was constructed to bear five tons.
