I'm trying to create on the "simple glazing systems window material" a material that have the same U-factor for the skylight with curb,glass,% of roof with the assembly of U-factor of 1.98 Btu/ft2.h.R for a Semiheated Space as specified on ASHRAE 90.1-2007 for Climate Zone 3A but for some reason doesn't let me pass 1.2 for I-P or 6.81 for SI.

Its there a maximum value for the U-Factor to create a simple glazing system or its bug a of my OS? Because every time that I try to change my U-factor it resets.
