Auburn Hills, Mich., April 8, 2008 -- Guardian continues to expand its architectural product line with the introduction of Guardian CrystalGray™, an innovative new float glass substrate with a very light gray tint, ideal for a wide range of architectural glass markets.

In addition to an attractive neutral color, Guardian CrystalGray offers an improved light to solar gain ratio compared to standard blue and gray tinted float glass. The technology behind Guardian CrystalGray allows higher light transmission while reflecting infrared energy, thereby reducing the heat gain for many architectural applications. This new float glass in combination with coatings can help buildings achieve LEED (Leadership in Energy and Environmental Design) certification.

“Architects consistently tell us that they want more neutral color options without sacrificing glass performance,” said Chris Dolan, director of Guardian’s commercial glass program. “Our CrystalGray product is an aesthetically pleasing neutral color that still transmits lots of natural light while offering impressive energy efficiency. When combined with high-performance coatings, CrystalGray reduces heat gain to levels achieved in the past only by highly reflective glasses.”

CrystalGray was developed for the high-performance architectural glass market through “voice of the customer” research with Viracon, Inc., Owatonna, MN. Viracon offers Guardian CrystalGray as part of its specialty float glass product line that also includes Guardian UltraWhite™ low-iron float glass. Guardian CrystalGray is available as uncoated glass and with SunGuard® Advanced Architectural Glass coatings, through the independent SunGuard Select™ Fabricator network. Like standard float glass, Guardian CrystalGray float glass can be used monolithically, tempered, laminated and fabricated. It can also be used on the exterior or interior lite of a vision insulated glass unit or in spandrel glass applications. SunGuard CrystalGray offers superior solar performance for insulated glass applications in commercial buildings.
