The architect's vision is that visitors will have the sensation of floating freely without the intrusion of visible supports and can enjoy a panoramic view.
What makes this technological marvel possible are materials from DuPont Building Innovations. Ultra-clear DuPont(TM) SentryGlas(R) Plus structural interlayers provide strength and stiffness plus optical clarity for the all- glass flooring that enables visitors to have an unprecedented viewing experience while standing safely on the observation platform. Analysis done by DuPont; the glass supplier, Saint-Gobain; and structural engineering consultants show that the laminated glass floor can hold the weight of up to 120 people and maintain a top safety rating even in the face of 100 miles per hour winds.
"DuPont has a long tradition of protecting people, properties and operations around the world by putting its science to work," said Craig Binetti, vice president and general manager -- DuPont Packaging & Industrial Polymers. "SentryGlas(R) safety glass is a high-performance material with structural properties designed to withstand high winds and weight loads and to meet high security standards for blast mitigation. These properties allow SentryGlas(R) to be used in places where glass could never be used before.
