A modular bank window construction having a main window frame and a glass frame within the main frame in which bullet-resistant glass is mounted. Window frames of various widths are assembled with the same vertical window frame components and with horizontal window frame components cut to various lengths depending on a selected window width. Various window widths are assembled using one or a plurality of standard sized bullet-resisting glass panels. The exterior portions of the main window frame may be clad with any one of a number of different thin sheet materials such as bronze, aluminum, stainless steel, and various colors of vinyl material to satisfy architectural specifications. The cladding and primary window frame components are constructed to provide weather-sealed joints at the primary frame corners and also between the main window frame and glass frame. Both the window and glass frames are adjustable to accommodate different wall and glass thicknesses; and the window frame has adjustable means to accommodate variations in the window receiving opening formed in a building wall. The glass frame is constructed to permit a glass panel to be replaced from the building exterior, and interior access is required only for securing bolts for the glass retention means. The main window frame contains a built-in raceway for cable wiring for electrical outlets, switch controls and electrical accessories.
