A storm window consisting of a rectangular window pane supported in a metallic frame is mounted over a window in a building by means of U-shaped channels mounted on the building and surrounding three sides of the building window. The storm window is slipped into channels and maintained in place by a friction or spring fit. The fourth side is closed by means of a U-shaped channel which is snapped or bonded onto the storm window frame.
