Why not just add an option in the window objects to not show the glazing?
Maybe some windows have this option already?
I don't know as I don't use the default Archicad windows.
It could even be set as a Model View Option so you can globally turn all glazing on/off.
Mind you the centre frames of the window would be very fragile in the model and you would need to add a lot of interior detail rather than just the external detail of the building.
