A rectangular steel frame has a wide peripheral flange integrally connected to a narrow peripheral flange by a web, and a set of spacer bars of predetermined thickness are welded to the narrow flange around the frame. A multiple layer glass unit is positioned within the frame, and a set of trim base strips are secured by peripherally spaced screws to the wide flange and to the spacer bars around the frame for capturing a peripheral portion of the glass unit. Steel reinforcing strips are secured to either or both sets of trim base strips by the screws, and corresponding sets of aluminum trim channels snap-fit onto the base strips around the frame for enclosing the steel reinforcing strips and to provide a neat decorative appearance. The above structure is also used to form a mullion within the window unit or a window frame assembly for a stepped opening in a building wall. Glazing materials extend between each set of trim base strips and the peripheral portion of the window unit.
A bullet resistant window assembly adapted to be installed in an opening of a building wall, comprising a generally rectangular metal frame having a first elongated peripheral flange rigidly connected to a second peripheral flange by a longitudinally extending web, said first flange having a width substantially greater than a width of said second flange in lateral cross-section of said frame, elongated base strips secured to said first and second flanges around said frame, said base strips each having opposite edge portions, a plurality of metal reinforcing strips secured to said base strips around said frame, trim members having portions releasably connected to said edge portions of said base strips around said frame and enclosing said reinforcing strips, a multiple layer glass unit within said frame and surrounded by said frame, said glass unit having a peripheral portion confined between said base strips and laterally overlapping only said first flange of said first and second flanges, and said reinforcing strips laterally overlap said frame and said peripheral portion of said glass unit.
