Press Release

May 23, 2006

Minneapolis, Minnesota. Cardinal CG Company recently introduced a new high-performance, energy-efficient coated glass called LoĒ³-366 (pronounced low E cubed 366). This latest innovation in sputter coating technology produces the ultimate coating for residential applications. Its SHGC (solar heat gain coefficient) of 0.27 is significantly better than that of tinted, ordinary low-e glass. LoĒ³-366 is virtually clear, with a visible light transmittance of 66% - nearly matching Cardinal's most popular glass options today.

"LoĒ³-366 delivers the highest visible light transmittance with the lowest SHGC of any coated glass on the market today," states Bowie Neumayer, National Sales & Marketing Manager. "It significantly reduces heat gain while letting the light stream in." Neumayer adds, "With the cost of energy continuing to make national headlines, we felt the need to press the envelope further by leveraging our technology to make the next product for energy efficiency and comfort. LoĒ³-366 does this and then some."

The technology behind LoĒ³-366 starts with Cardinal's sputter coating process. Using the double silver platform that has proven to be the key to Cardinal's success in the marketplace, Cardinal's R&D group incorporated a third layer of silver to make LoĒ³-366. The result is a coating that works in every geographic location, delivering superior performance, minimal exterior reflectance with high visible light transmittance.

LoĒ³-366 is available now.
