Abstract: A window frame for use with a window assembly with a sash slidably mounted in the window frame, the sash having a top rail, a bottom rail, and a first and a second stile extending therebetween. The window frame includes a head member, a sill member defining a first channel for receiving the bottom rail of the sash when the sash is in a closed position and a trough extending along a bottom of the channel. A pair of jambs extends between opposing ends of the head member and the sill member. The trough is adapted to allow water to pass to a first interior volume of the sill member such that the water is directed to an exterior side of the sill member.
