PPG introduces SOLARBAN z50 glass design kit

PITTSBURGH, Sept. 19, 2007 – PPG Industries (NYSE:PPG) has introduced a glass design kit for Solarban z50 glass, a new solar control low-emissivity (low-e) glass with a steely blue-gray appearance.

The new glass design kit shows Solarban z50 glass in combination with six clear and tinted glasses from PPG in standard one-inch insulating glass units. The resulting hues, which range from a luminous aqua-blue to soothing light-gray tints, demonstrate the ability of Solarban z50 glass to produce the wide range of aesthetic options architects desire. Solarban z50 glass also demonstrates lower exterior reflectance than other similarly tinted glasses.

Designed to meet architects’ growing demand for a neutral-gray glass, Solarban z50 glass represents a significant advance in the architectural glass industry because it offers higher visible light transmittance and better solar control that competing glasses with similar tints. As a result, it has the potential to help architects and building owners dramatically reduce the amount of energy their buildings consume.

In a recent study conducted by an independent environmental and energy services firm, Solarban z50 glass demonstrated the ability to reduce annual energy costs by 10 percent in an eight-story office building when specified in place of conventional dual-pane tinted glass.

The same study showed that, because of this lower energy demand, architects and building owners could reduce initial investments in heating, ventilation and air conditioning (HVAC) equipment by more than $300,000 while also cutting carbon dioxide emissions by more than 400 tons per year, depending on the city in which the building is located.
