A storm window includes a frame having side jambs interconnected at their upper and lower ends by a head and sill, respectively. The frame receives an upper stationary window sash and a lower movable window sash. Sealing flanges extend inwardly from the side jambs and top rail along the entire length thereof. The flanges are coplanar one with the other. A midbrace is attached between the side jambs intermediate of the head and sill and includes a flange coplanar with the sealing flanges extending from the side jambs and head. The upper stationary sash window has a planar sealing surface around the periphery thereof for sealing engagement against the sealing flanges of the head, side jambs and midbrace. The lower movable window sash has a planar sealing surface around the periphery thereof for sealing engagement against the surface of the sealing flanges of the midbrace and side jambs opposite the surfaces of these members against which the upper stationary window sash seals. The upper stationary window sash is mountable within the storm window frame and retained therein without requiring any retaining structure in addition to the surround frame.
