DuPont Expands SentryGlas® Offerings for Hurricane-Resistant Windows and Doors

Wilmington, Del., August 7, 2008 - DuPont is expanding the range of DuPont(TM) SentryGlas® interlayers to meet a broader range of needs for protective windows, doors and safety-glazed building elements.

The newest SentryGlas® is available in thinner sheets that provide protection while replacing thicker traditional interlayers. The new offerings broaden architects' and builders' choices for incorporating impact-resistant glass for more protective buildings. And, engineers can design stronger, more durable, more protective building elements such as skylights, rails, stairs, doors or storefronts.

"DuPont brings a long history of safeguarding people, property and operations around the world by putting its science to work," said William F. Weber, vice president and general manager -- DuPont Packaging & Industrial Polymers. SentryGlas® interlayers are 100 times stiffer and five times tougher than traditional interlayers, delivering strong protection against storm damage, forced entry, accidental injuries and even bomb blasts."

In addition to supplying protective materials, DuPont has done extensive work in providing counsel to Gulf and Atlantic Coast states on stronger building codes and storm proofing, helping to enact hurricane building codes in Florida in 2007, and Mississippi and Louisiana in 2005 following damage in the wake of Hurricanes Katrina and Rita. Hundreds of glazing systems have been tested and approved to meet tough new codes using SentryGlas®.

DuPont manufactures and markets products for residential and commercial construction that provide high-performance weather and climate protection for buildings and their occupants, as well as sustainable energy management systems. In addition to DuPont(TM) SentryGlas®, these products include: the DuPont(TM) StormRoom(TM) with Kevlar®, DuPont(TM) Corian® and Zodiaq® solid surfaces, Granite Certified by DuPont(TM), DuPont(TM) RoofLiner with Elvaloy®, DuPont(TM) Tyvek® Weather Barrier Systems including Tyvek® AtticWrap(TM), the first breathable roofing membrane to create an airtight attic, and Tyvek® ThermaWrap(TM), which helps reduce energy costs and increase comfort by improving the reflection of radiant energy in wall systems.
