PERFORMANCE DATA TABLES<br />
Insulating laminated low-E (Air Filled)<br />
The performance data applies to insulating laminated glass constructed with three plies (clear inboard laminate) of 1/4" (6mm) glass,<br />
a .060 (1.52mm) clear polyvinyl butyral (PVB) interlayer and a 1/2" (13.2 mm) airspace. The coating is applied to the second (#2)<br />
surface.<br />
The solar and optical data presented in this guide is center of glass data based on the National Fenestration Rating Council<br />
measurement standards. They were calculated using Lawrence Berkeley National Laboratory’s (LBNL) WINDOW 5.2/6.3 software.<br />
In some cases performance data changed in comparison to previous versions of LBNL’s WINDOW program.<br />
