Is there an exemption for rating Clerestory Windows in IBC 2006?  When I look at Table 715.5 it looks its 90 minutes?  I see an exemption for wire glazing but openings are only 100 sq in.  The existing window panels are much larger.  Building was built in 1971, type 1A, B occupancy.  Clerestory windows face each other and are 16' apart.  

Any info is greatly appreciated!
