Performance Data Overview
The bulletin outlines performance characteristics for Cardinal's LoĒ® insulating glass products, including various glass thicknesses and coatings. It provides comparative data on U-values, shading coefficients, and solar heat gain coefficients for different glass combinations, helping users understand the thermal performance of each option.
Product Comparisons
The document compares several insulating glass units with different glass substrates and coatings, such as clear, green, gray, and bronze glass. It highlights how these combinations affect performance metrics like visible light transmittance and UV transmittance, which are crucial for energy efficiency.
Calculation Notes
Performance data is calculated using the Window 6.3 computer program under NFRC 100-2010 environmental conditions. The calculations are based on specific airspace and glass thicknesses, ensuring accuracy in the reported values.
Recommendations
Cardinal recommends specific combinations of glass substrates and coatings to avoid potential issues such as thermal stress and breakage. The bulletin advises against using certain coatings on tinted substrates and provides guidelines for optimal product selection.
Safety and Disclaimer
The bulletin includes disclaimers regarding the use of the data provided, emphasizing that the information is subject to limitations and should be used in conjunction with professional judgment.
Safety notes
- Cardinal does not recommend the use of LoĒ® coatings on tinted substrates due to potential thermal stress issues.

technical SERVICE BULLETIN Bulletin #IG05– 04/13 1 of 6 Performance Data and Comparisons The performance characteristics of Cardinal’s LoĒ® products are shown on the attached “Insulating Glass Performance Comparison” charts. The following products and combination of products are compared: • IG units with nominal 3 mm and 6 mm glass substrates; • IG units with clear, green, gray, and bronze non-coated glass substrates; • IG units with LoĒ²-272®, LoĒ²-270®, LoĒ3- 366®, and LoĒ²-240® on the #2 glass surface; • IG units with LoĒ-180® on the #2 or #3 glass surfaces; • IG units with green, gray, or bronze outdoor glass substrates with LoĒ-180®, LoĒ²-272®, LoĒ²-270®, LoĒ3-366®, LoĒ²-240® or LoĒ- 180® on the #3 Indoor glass surface; • IG units with LoĒ²-272®, LoĒ²-270®, LoĒ3- 366®, LoĒ²-240® or LoĒ-180® on the #2 glass surface with LoĒ-i89 on the #4 glass surface. Although the Winter U-factors are not affected when Cardinal’s LoĒ® coatings are used on the #2 or #3 glass surface, the Shading Coefficient and Solar Heat Gain Coefficient will be higher when the coatings are on the #3 glass surface compared to the #2 glass surface. Cardinal does not recommend the use of LoĒ® coatings on tinted substrates; therefore, there is no performance data listed for these combinations. However, Cardinal will supply IG units with a tinted lite outdoors and clear LoĒ® coated products on (surface #3) indoors. Cardinal also does not recommend solar control LoE® coatings (LoĒ²-272®, LoĒ²-270®, LoĒ3-366®, and LoĒ²-240®) be used on the #3 surface of a dual pane IG unit with a clear outdoor lite. The potential for having inside glass breakage from thermally- induced stress is increased. These coatings are designed as second surface coatings in a dual pane IG unit. The only LoĒ® coating recommended for use on the #3 surface of a dual pane IG unit with a clear outdoor lite is LoĒ-180®. technical SERVICE BULLETIN Bulletin #IG05– 04/13 2 of 6 Cardinal Double-Pane Insulating Glass Performance Data 3 mm / 13.0 mm airspace / 3 mm Exterior Glass Interior Glass Visible Light SC SHGC Center of Glass U-Value (BTU/hr/ft²/°F) Comfort UV Trans.

(2) Calculations based on 13 mm (1/2") airspace, 3 mm (1/8") glass, and 90% Argon gas fill level. (3) Comfort Indoor Glass Temperatures are for the center portion of the glass. (4) Shading Coefficient (SC) can be calculated by dividing SHGC by 0.87. (5) The UV Transmittance is determined as an average for wavelengths 310 -380 nm. (6) UV Damage Weighted Transmittance (Tdw) is the weighted average for wavelengths 300 - 700 nm (based on CIE 89/3).
