Thermal Break Window Fenestration Formed of Steel

A fenestration system with a thermal break comprising:

• a first thermal break system, forming an edge perimeter of the fenestration, formed of a solid block of thermal break material adjoining on one side a length of tube steel and on the other side a structural metal;
• a structural connector, connecting between said structural metal, said solid block of thermal break material and said length of tube steel to form a structurally combined thermal break assembly;
• where the structurally combined thermal break assembly extends all the way around a perimeter of the fenestration, and includes a first inside surface for holding fenestration glass, and a second outside surface for connecting to structural framing,
• where both the inside surface and the outside surface each have a flat area formed by the block of solid block of thermal break material and a surface of the tube steel,
• and where the outside surface adjoins and connects to a framing piece, and where the inside surface forms a flat surface on which the fenestration glass is attached and where the fenestration glass is held between the structural metal and another metal piece attached to the structurally combined thermal break assembly.
