Claim 11:
12. A method of forming a thermally broken structural member for a window, comprising:
forming a space separating a first extrusion from a second extrusion by at least 40 mm, the first extrusion at least partially defining a first side of the window, the second extrusion at least partially defining a second side of the window opposing the first side;
after forming the space,
using an insulating coupler to span the space and to rigidly couple the first extrusion to the second extrusion to form a thermally broken structural member separating the opposing sides, and
rigidly coupling a second insulating coupler to the first extrusion and the second extrusion to form a cavity between the first insulating coupler and the second insulating coupler;

engaging frictionally with the first extrusion with a first stiffener structure;
engaging frictionally with the second extrusion with a second stiffener structure; and
coupling the first stiffener structure and the second stiffener structure using an insulating stiffener coupler to provide structural support and to hinder thermal bridging between the first stiffener structure and the second stiffener structure.
