Grand Canyon Skywalk uses SentryGlas® for strength

Safety glass with SentryGlas® high strength interlayerThe 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.
Safety glass with SentryGlas® high strength interlayerU-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.
