PERFORMANCE DATA TABLES
Triple Insulating Double Coated Low-E (Air Filled)
The performance data applies to triple insulating glass units with three plies (clear lites unless otherwise specified) of 1/4"
(6mm) glass and two 1/2" (13.2mm) airspaces or argon spaces. The coating is applied to the second (#2) surface. If double coated,
a VE-85 coating is applied to the fourth (#4) 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.
