DuPont Safety Glass Makes New Grand Canyon Skywalk Possible

WILMINGTON, Del., March 20  /PRNewswire-FirstCall/ -- When visitors step out on the new U-shaped Grand Canyon West Skywalk observation platform, they will be standing on all-glass flooring suspended 4,000 feet above the Colorado River.  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. "

The two-inch thick glass decking, approximately 10 feet wide and 70 feet deep, is made of a multilayer glass construction including three SentryGlas(R) Plus structural interlayers and four layers of Saint-Gobain Diamant(R) glass.

DuPont(TM) SentryGlas(R) has been chosen for a number of innovative and award-winning installations worldwide such as for: ultra-clear viewing panels for the Top of the Rock observation deck at New York City's Rockefeller Center; wind and bomb resistant windows for the Miami, Florida U.S. Federal Courthouse; glass staircase steps and balustrades in a number of Apple Stores worldwide, and; the uniquely designed Shanghai Oriental Arts Center in China, among many others.
