Abstract: The present invention comprises an insect screen and a security barrier contained within a removable frame installable to replace a conventional screen or storm window, the assembly functioning both as a barrier to insect penetration, and as a security barrier to deter an intruder from entering the building through the window or door. The main components of the window guard insert comprise a frame assembly, a security barrier, an insect screen, a spline, and a weather strip. The assembled frame includes a security barrier channel to retain the security barrier, a weather strip channel to retain the weather strip and an insect screen channel, partially formed by the security barrier to retain the insect screen. An optional clip retaining channel is used to increase the window guard insert's ability to withstand an unauthorized entry attempt.

Abstract: A window storm shield and guard assembly installable to fit within the jamb of a building window, or to fit onto the face of the building surrounding the jamb, the assembly, functioning both as a storm barrier to protect the window from strong winds and wind-borne debris, and as a security barrier to deter an intruder from entering the building through the window. The main components of the assembly are a main frame defining a rectangular socket, and a barrier frame which is normally nested in the socket and supports a perforated metal barrier panel that reduces but does not block the passage of light and the flow of air through the panel. The barrier frame is hinged at its upper end to the corresponding end of the main frame, and at its lower end, the barrier frame is latched internally to the corresponding end of the main frame. In the closed mode of the assembly in which the barrier frame is nested in the main frame and is latched thereto, the window is then fully protected.
