Metal reinforced mullion for windows

摘要

A window assembly includes adjacent first and second windows and a reinforcing mullion connecting the windows. The mullion comprises hollow polymeric first and second lineals and a metal reinforcing bar between the lineals. Interior and exterior face caps attached to the lineals span a gap between them. A securement means is also provided for connecting an end portion of the metal reinforcing bar to a support structure surrounding a window opening in a building. The mullion adds rigidity to the assembly, thereby increasing its design allowable size.
