CARLISLE, Pa., Nov. 9, 2010 – One inch-thick (25 millimeter) STARPHIRE(R) ultra-clear glass, specially manufactured for One World Trade Center, rolls along the production line at PPG Industries’ (NYSE:PPG) Carlisle Glass Works in central Pennsylvania.

The building, also known as Freedom Tower, is currently under construction at the new World Trade Center complex in lower Manhattan. The glass was selected specifically by the tower’s design and engineering teams for its thickness and clarity. It will be the signature element in a 185 feet-tall podium glass wall that will incorporate more than 2,000 pieces of prismatic glass and welded aluminum screens. When completed in 2013, One World Trade Center will reach 102 stories and 1,776 feet, making it the tallest building in the United States.

PPG Industries is one of few glass companies worldwide that can manufacture ultra-clear glass in thicknesses of up to one inch (25 millimeters), as specified by the building designers. Founded in 1883, the company was the first commercially successful plate glass manufacturer in the United States.
