Abstract: A storm-resistant window includes a mechanism for preventing the blowout of a movable sash when wind pressure pulls the sash outwardly. In a single hung window having a slidable lower sash, the mechanism consists of a first rib projecting downwardly from the bottom rail of the lower sash and a second rib projecting upwardly from the top of the sill member of the window frame. In a closed position of the window, the first rib lies inwardly adjacent the second rib such that, if wind pressure pulls the movable sash outwardly, the first rib will contact the second rib, preventing the bottom rail of the movable sash from moving outwardly. In an alternate embodiment, one of the ribs may be replaced with a channel, so that the remaining rib is received in the channel in the closed position of the window.
