Best CW setting

[yes_and_no]

What is your best curtain wall setting for storefront that has fixed 6'4" module in the center, yet allows maximum 5' mullion modules on both wings ?

This will help a lot. Thx

I would use a curtain without any pre-assigned division and place grids manually. 

Or place the 6'-4" division first, then change the panel on either side to another curtain wall type with maximum 5' grid spacing.
