WINDOW FEATURES:
A. Dual insulated, both lites Clear, DuraLite® Spacer-Lowest Insulating Value
B. Dual insulated Cardinal 270 LoE²-2 layers of LoE Coating (surface 2) with argon fill, DuraLite® Spacer -Twice the Insulating Value of Clear
C. Dual Insulated Cardinal 366 LoE³-3 layers of LoE Coating (surface 2) with argon fill, with Neat® glass, DuraLite® Spacer
D. Triple Cardinal 270 LoE² – 4 layers of LoE Coating (surface 2 & 5) with argon fill, XL Edge
E. Triple Cardinal 366 LoE² – 6 layers of LoE Coating (surface 2 & 5) with argon fill, XL Edge
The data shows that the overall U-factor and in turn heat loss are significantly reduced with Cardinal LoE² and LoE³ products over clear IG units.

This table shows how Cardinal LoE coatings and argon filling improve the center of glass U-value.
The above figures are tested center of glass U-values used for comparison between options.
Complete window U-values will vary and include other factors such as air infiltration rates and frame construction.
