GLAZING OPTIONS
A. Dual insulated, both lites Clear, DuraLite® Spacer – Lowest Insulating Value
B. Dual insulated Cardinal 270 LoE² – 2 layers of LoE Coating (surface2) 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, DuraLite® Spacer

The data clearly shows that the overall U-Factor and heat loss significantly reduces 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.
