THERM 5 files should now have the exterior frame boundary conditions tagged with a U-factor tag of SHGC Exterior, which calculates the exterior wetted length of the frame for the Solar Heat Gain Coefficient calculation in Berkeley Lab WINDOW 5. If that tag is not present in a THERM 5 file imported into the Berkeley Lab WINDOW 5 Frame Library, a message will appear at import time saying:

This means that the program will use the Frame U-factor tag length for this calculation, which is on the interior of the profile. To do the calculation correctly, tag the THERM 5 file with the SHGC Exterior U-factor tag.
