a second extrusion spaced apart from the first extrusion;
an 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 stiffener extending between the first extrusion and the second extrusion to stiffen the structural member, the stiffener including
a first stiffener end engaged with the first extrusion and spaced apart from the second extrusion,
a second stiffener end engaged with the second extrusion and spaced apart from the first extrusion, and
