A. Dual insulated, both lites Clear, DuraLite® Spacer-Lowest Insulating Value
B. Dual insulated Cardinal 270 LoE²-2 layers of LoE Coating (side 2) with argon fill, DuraLite® Spacer -Twice the Insulating Value of Clear
C. Dual Insulated Cardinal 366 LoE³-3 layers of LoE Coating (side 2) with argon fill, with Neat® glass, DuraLite® Spacer
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.
|Center of Glass U-value (Btu/hr/ft²/°F)||0.48||0.25||0.24|
This table shows how Cardinal LoE coatings and argon filling improve center of glass U-value.
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 and frame construction
*Above options can be made with obscure, tempered or tinted glass.
