DuPont(TM) Tyvek(R) Products Specified for City's Key Commercial Construction Projects MOSCOW, Oct. 4 /PRNewswire-FirstCall/ -- DuPont (NYSE:DD) innovations play a critical role in enhancing the energy efficiency of the Elite House in Sokolniki -- a skyscraper currently under construction here that, when complete, will be one of the tallest buildings with DuPont(TM) Tyvek(R) in the world, at 43 floors and 153 meters high. "DuPont is committed to delivering innovative, energy efficient and safe construction solutions that address the extreme climate conditions of Russia," John Shmorhun, regional director, DuPont Eastern Europe, said. "We are pleased to see our products used in an increasing number of Russian building projects as we strive to meet the needs of the country's growing construction industry." Construction is a key industry in Russia with an expected 15 percent growth in 2007, accounting for 7 percent of the total Russian GDP. The construction industry in Russia will continue to experience double-digit growth as it strives to keep up with the demands of the growing Russian economy," Shmorhun said. "DuPont is using its science to help deliver safer, more comfortable and ecologically sound facilities." The Elite House in Sokolniki is equipped with a concrete frame and ventilated facade. DuPont(TM) Tyvek(R) HomeWrap(R) is used as an underlay on top of mineral wool to protect it from wind, dust and water from rain and melting snow. Tyvek(R) helps to reduce energy loss due to uncontrolled air infiltration, helps minimize condensation to protect the building structure, and preserves the integrity of the insulation material. This facade technology has several important advantages over other facade types in harsh environments where the continental climate dominates and great ranges of temperature are typical. The technology, which was developed in Russia with adaptation of some European elements, was recommended by the Russian Construction Ministry.
