The 2012 and 2015 IBC limits the size of ceramics and fire protective glazing used in the door vision panel in 60-90 minute exit stairway or passageways to 100 sq. in. regardless if the building is fully sprinklered. The only way to exceed the 100 sq. in. vision panel limitation is by using fire resistive glazing that meets ASTM E-119.
