DuPont demonstrates hurricane code test during South Florida's Fourth Annual Hurricane Conference

In the first-ever, live demonstration of a hurricane code test using an occupied building, DuPont fired a 4.5 kilogram, 5 x 10 cm wooden plank at the Broward Center during South Florida's Fourth Annual Hurricane Conference in May 1998. The test, covered by leading US journalists that SentryGlas^® Plus interlayer for laminated glass is the new industry standard for security and storm protection.

One of South Florida's crowning architectural and cultural jewels – the Broward Center for the Performing Arts – provided a glorious setting for the first 'live' testing of Dupont SentryGlas^® Plus Ionoplast interlayer during the Fourth Annual South Florida Hurricane Conference (May 1998). At the Conference, the Broward Center announced that it intends to replace 1,580m² of its existing glazing with laminated glass containing the new Ionoplast interlayer.

Cannon-fired 2x4 cracks glass but doesn't break through window.

President of the Broward Center, Mark Nerenhausen, explained: "It is our obligation to keep The Broward Center safe and protected. Hurricane force winds or even a strong storm could do a lot of damage to our windows, which are only tempered glass. We are exploring this new technology which could offer us the protection of our building at a significant saving."

Speaking at the Hurricane Conference, DuPont worldwide Architectural Manager for Glass Laminating Products, Jeff Granato, said: "Over the past four years, we have listened to the needs of architects, builders and homeowners who were searching for an all-glass surface product with greater durability and wind load resistance to protect their businesses and homes."

"DuPont has invested $13 million in research and development to fulfill that need. The end result is that we have delivered a technology for laminated glass that offers a two-sided glass surface with higher design pressure ratings and greater utility for a broader range of applications." Granato also pointed out that SentryGlas^® Plus is cost-effective, priced substantially lower than other products being developed for larger window applications.

SentryGlas^® Plus offers higher wind cycling pressure capabilities, five times the tear strength and 100 times the rigidity of conventional PVB. Because of its added strength and clarity, as well as its fabrication and installation ease, the product can be used in commercial buildings and homes that feature large open glass areas.
