Viracon's solar and optical performance data is center of glass data based on the National Fenestration Rating Council measurement standards, calculated using Lawrence Berkeley National Laboratory's (LBNL) WINDOW 7 software.

Winter and Summer U-Values are the only performance values available for spandrel glazing. The U-Values for spandrel glazing are the same as the corresponding vision unit. The spandrel color does not impact U-Value.
