PERFORMANCE DATA TABLES
Insulating Low-E (Air Filled)
The performance data applies to insulating glass units with two plies (clear inboard) of 1/4" (6mm) glass and a 1/2" (13.2 mm) airspace
or argon space. The coating is applied to the second (#2) surface.
The solar and optical data presented in this guide is center-of-glass data based on the National Fenestration Rating Council
measurement standards. They were calculated using Lawrence Berkeley National Laboratory’s (LBNL) WINDOW 5.2/6.3 software.
In some cases performance data changed in comparison to previous versions of LBNL’s WINDOW program.
