All test results have been achieved through independent testing.
NFRC Results are expressed as an overall U-Value and include Powerpane Plus glazing.
Energy rating has been calculated using the NRCanada ENERGY STAR formula for Energy ratings. A higher number indicates better performance.

Glazing Performance Data

Powerpane includes a patented insulated space bar.
Powerpane Plus includes one Low E coating, Argon Gas, patented insulated space bar.
All glazing data is based on NFRC Methodology, using LBNL’s Window 5.2 Software.
U-Value (K-Value) is the overall coefficient of heat transmittance measured in
BTU / hour / ft / °F (watts/meter2 °K) lower U-Values indicate better insulating performance.
Shading coefficient is the ratio of the total amount of solar energy that passes through a glass relative to 3mm (1/8") thick clear glass under the same design conditions. A lower shading coefficient indicates better performance in reducing summer heat gain.
