A bank window frame structure wherein bullet-proof glass is installed from the outside of a bank building wall in which the frame is located, and the glass is clamped in the frame in a weather-proof manner with a sealed joint all around by clamping means accessible only at the inside of the building wall. All sill, head and side frame members are composed of cut lengths of formed channel-shaped, sheet metal, base and support members secured together in box-like cross-sectional arrangement. The glass is installed from the outside of the frame, with sealing gasket means around its perimeter, and is retained by a formed sheet metal retaining channel member which compresses the sealing gasket means to provide the weather-proofed joint. The clamping screw means for the retaining channel is accessible only at the inside of the frame. The simple bullet-proof glass window construction with a frame of formed sheet metal members is inexpensive to fabricate and install as a window of any desired size for a banking building.
