Claim 3:
4. A structural member for a window, the structural member being a mullion, the structural member comprising:
a first extrusion;
a second extrusion spaced apart from the first extrusion;
a first insulating coupler assembly defining a first lateral end of the structural member between the first extrusion and the second extrusion, the first insulating coupler assembly including
a first insulating coupler extending between the first extrusion and the second extrusion to couple the first extrusion to the second extrusion to form the structural member and hinder thermal bridging of the first extrusion and the second extrusion, and
a second insulating coupler separate from the first insulating coupler and extending between the first extrusion and the second extrusion to couple the first extrusion to the second extrusion to form a cavity between the first extrusion and the second extrusion for receiving insulation material, each of the first and second extrusions extending between the first and the second insulating couplers to separate the first and second insulating couplers and to structurally couple the first and second insulating couplers to each other, the cavity extending from the first extrusion to the second extrusion and defined between the first insulating coupler and the second insulating coupler; and

a second insulating coupler assembly defining a second lateral end of the structural member between the first extrusion and the second extrusion, the second lateral end opposite the first lateral end.
