There are many heads listed for exposure window protection, but not window protection for interior or the building. I think TYCO has the only window sprinkler that gives you an equivalent to 1 hour wall rating for glass, at this time.
7.8.8.4 For protection of window and similar openings, listed window sprinklers shall be positioned within 2 in. (50.8 mm) of the top of the window sash in accordance with Table 7.8.8.4. Listed window sprinklers for exposure protection cannot be used for interior windows in a rated wall.
