China’s Guangzhou TV building utilizes heat-reflective XIR® film to improve energy efficiency, maximize daylighting and increase occupant comfortPALO ALTO, Calif. -- Southwall Technologies Inc. (OTCBB:SWTX), the worldwide innovator of energy-saving films and glass products, today announced one of its largest architectural glass project wins, the Guangzhou TV building in China.

Currently under construction alongside the world-renowned Guangzhou TV and Sightseeing Tower, the landmark building utilizes Southwall’s heat-reflective XIR film to minimize solar heat gain while maximizing visible light and energy efficiency. This is the second largest project win for Southwall in China after the Universiade Center sports complex in Shenzhen.

Southwall’s XIR film was selected for its clear solar control performance which saves energy while providing for optimal daylighting and a clean, architectural design. Laminated between 15 mm clear tempered low-iron glass covering 26,000 square meters (280,000 square feet) of the building envelope, the XIR film blocks over 50 percent of the sun’s heat (shading coefficient of 0.49) with visible light transmission of greater than 60 percent, providing a cool and comfortable environment that lowers HVAC system loads and operating costs. The XIR film maximizes clarity with reflectance of just eight percent and reduces interior fading by blocking 99.5 percent of UV rays. The monolithic nature of the glass also brings additional safety and flexible glazing design benefits.

“With our heat-reflective XIR film, we are proud to equip the Guangzhou TV building with unequaled protection from the sun’s heat while providing superior daylighting and energy-efficiency,” said Dennis Capovilla, president and chief executive officer of Southwall Technologies. “This landmark project represents one of the largest architectural glass projects in our company’s history, signaling our continued growth within the global marketplace.”

The high-performance XIR laminated glass is being specified and supplied by Shenzhen Kaisheng Energy Saving Technology Co. Ltd, Southwall’s Master Distributor of Architectural XIR products in China. Glazed monolithically or combined into sealed insulating glass units, XIR film enables a unique, low-reflectance appearance while blocking approximately 50 percent of invisible heat. Unlike glass coatings, XIR film was developed specifically to support the laminating process and can be laminated with low-iron, annealed, heat-strengthened or tempered clear glass, or combined with tinted PVB and tinted glass for maximum design flexibility.
