The present invention provides a double-hung window assembly having at least one sash slideably mounted within a frame. Elongate stops are secured along opposite sides of the slideable sash and are moveable between first positions interengaging a respective side of the frame and second positions free of engagement with the frame. When the stops are in their first positions, the sash is constrained to move in a linear path relative to the frame. When the stops are in their second position, the sash is free to pivot relative to the frame about pins or similar structure extending between the sash and the frame.
