Low-E glass

The coated glass division of Cardinal Glass Industries, Eden Prairie, Minn., introduced a high-performance, energy-efficient coated glass, LoE-i81. The sputter coated low-E is applied on the interior lite of an insulating glass unit, or the No. 4 surface of a double-pane window. When coupled with Cardinal LoE3-366 glass and argon fill in a double-pane IG unit, it gives a center-of-glass U-factor of 0.20. Without argon, and with or without capillary tubes, the unit delivers a U-factor of 0.23. LoE-i81 offer visible transmittance of 81 percent, according to a release.
