I think only horizontal mullions are considered an obstruction to
wetting the glass. Also, in IBC 2013, the sprinkler equivalent for
Fire Rated is no longer approved.
Quoting Rod DiBona <[email protected]>:
Pretty sure you do. The mullion acts as a barrier. More than likely
if you present the dilemma to the A/E team they change the window.

Subject: Window sprinklers
I have two windows, each 2'-6" wide, separated by a vertical
mullion. Do I need two window sprinklers?
