Standard glass is insulating LoĒ2
with argon. Variables influencing thermal performance include window size and operating style, the number of panes - single, double or triple, the amount of air space between panes, glass thickness, the dimension and type of spacer bar, LoĒ coatings, grilles and lites, and the addition of argon or krypton. Window products can be specified for high energy efficiency.
Tripane glazing, available with argon or kryton gas, provides excellent energy performance. It's available with LoĒ2
-272 on both panes, with LoĒ-179®
on both panes for high SHGC, or with LoĒ3
on the exterior pane and LoĒ-179 on the interior pane for low SHGC.
