A window assembly includes a polymer (e.g., polyvinyl chloride, vinyl) window frame made and a glass unit carried by the window frame. The window frame includes a pair of jambs and an astragal that extends between and interconnects the pair of jambs. The jambs have a channel or slot sized to receive therethrough one or more end walls of the astragal so that at least a portion of said one or more end walls extend into a hollow cavity in the jambs that is in fluid communication with one or more weep holes of the window assembly. The one or more end walls of the astragal and channel or slot of the jambs define a flow path configured to channel water from the astragal, through the channel or slot in the jambs and into the hollow cavity such that said water exits the hollow cavity and the window assembly via the one or more weep holes.
