Grand Canyon Skywalk uses SentryGlas® for strength
 | The Grand Canyon Skywalk glass floor can hold the weight of up to 120 people, and is designed to handle winds up to 100 miles per hour. |
 | U-shaped Grand Canyon West Skywalk in Arizona projects out from the canyon rim, 4,000 feet above the Colorado River. |
When visitors step out on the new U-shaped Grand Canyon West Skywalk observation platform in Arizona, they will be standing on all-glass flooring suspended 4,000 feet above the Colorado River. Visitors get the sensation of floating freely without the intrusion of visible supports, to enjoy a thrilling panoramic view.
What makes this technological marvel possible is ultra-clear DuPont™ SentryGlas® structural interlayer. Its strength, stiffness and optical clarity in the all-glass flooring 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™ SentryGlas® safety glass interlayer 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 glass made with SentryGlas® 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® structural interlayers and four layers of Saint-Gobain Diamant glass.
