A steel window structure for modern day double paned insulating glass simulating the narrow, elegant sight lines of older steel window structures which secured monolithic, non-insulating glass windows is described. The window securing structure is made deeper and narrower than is currently available in steel windows. This structure now accommodates a single pane of glass of up to 1'' thick glass, or up to 1'' thick double paned insulating glass. Additionally the new structure inherently provides a thermal break between exterior and interior metal components, the convenient use of two color factory applied finishes for the steel members, and superior air and water resistance over current structures, while at the same time providing the narrow sight lines previously seen only in the older, non-insulating glass steel window structures. Moldings connected to the exterior steel structure provides a "putty slope" shadow effect to complete the simulation of the older steel window structure.
