Engineered Glass Products Earns UL(R) Approval for Thermique(TM) Heated Architectural Windows; Exclusive Technology Transforms Glass into Source of Radiant Heating

April 17, 2006

CHICAGO--(BUSINESS WIRE)--April 13, 2006--Engineered Glass Products (EGP) has earned UL approval for its new line of heated windows with Thermique(TM) technology for residential and commercial buildings. Architectural windows are among the first commercialized products designed with Thermique(TM) heated glass, which was pioneered exclusively by EGP engineers. As the first company to achieve UL approval for heating windows, EGP is the only company approved to provide heated glass technology for architectural use in the United States. Thermique(TM) windows radiate warmth and comfort into a room, no matter how low the temperature drops outside the building. Outdoors it may be well below freezing, but the interior surface of the glass will remain above room temperature--up to 105 degrees Fahrenheit, depending on user settings. This is accomplished with a transparent conductive oxide (TCO) coating and copper buss bars that are applied to the glass during fabrication. The TCO coating can be electrically heated with precise temperature control through the use of a Thermique(TM) Hot Glass controller designed by EGP specifically for the safe heating of Thermique Hot Glass. The glass is always uniformly heated across the entire pane. It is never too hot to touch so it is never a hazard, even with small children. The controller is even able to sense a fault or a crack in the glass, at which point it safely cuts off power. "With UL approval, architects, builders and owners can be confident that Thermique(TM) heated windows are a safe, responsible choice," says Pete Gerhardinger, vice president of technology at EGP. "Every new technology has to prove itself in independent testing, and we're proud to have accomplished this important process so quickly. The UL Listing is a testament to EGP's thorough development and testing process, which ensures a safe and robust product for our customers."
