1. A system for insulating a curtain wall structure connected to a building structure, the curtain wall structure spaced from a floor slab of the building structure to define a perimeter void and the curtain wall structure having framing defined by at least first and second vertically disposed and parallel mullions, and a horizontally disposed transom, the system comprising:
a plurality of insulation hangers, each insulation hanger having a hanger body that includes a vertical leg, a first horizontal leg, a second horizontal leg, and at least one reinforcing member, wherein the vertical leg extends between and connects the first horizontal leg and the second horizontal leg, wherein the first horizontal leg and the second horizontal leg are parallel to one another and extend from the vertical leg in a first direction, and wherein the at least one reinforcing member extends from the vertical leg in a second direction, the first direction and the second direction being opposite of one another;
a curtain wall insulation having opposed outer and inner surfaces and opposed top and bottom surfaces; and
a safing insulation having opposed outer and inner surfaces and opposed top and bottom surfaces;
wherein each insulation hanger engages the curtain wall insulation such that the first horizontal leg abuts the top surface of the curtain wall insulation, the vertical leg abuts the outer surface of the curtain wall insulation, and the second horizontal leg passes through the outer surface of the curtain wall insulation and extends into the curtain wall insulation;
wherein each insulation hanger is attached only to the horizontally disposed transom to secure the curtain wall insulation within the framing;
wherein the at least one reinforcing member of each insulation hanger engages a bottom surface of the horizontally disposed transom; and
wherein the safing insulation is disposed within the perimeter void and compression fit between the curtain wall insulation and the floor slab.
