Thermally enhanced multi-component glass doors and windows

A building component comprising:

• an insulated glass unit including:
• a first glass pane having an outer surface;
• and
• a second glass pane having an outer surface, wherein the second glass pane is spaced from the first glass pane, the first glass pane and the second glass pane defining a pocket therebetween, wherein a central plane extends through the pocket and is spaced equal distances from the first glass pane and the second glass pane;
• a frame supporting the insulated glass unit, the frame including a first side, a second side, and a middle portion intermediate the first side and the second side, the middle portion of the frame supporting the insulated glass unit, the first glass pane of the insulating glass unit is an outermost pane on the first side of the frame and the second glass pane of the insulating glass unit is an outermost pane on the second side of the frame;
• and
• an insulating material in the middle portion of the frame, the insulating material defining a continuous frame thermal break circumscribing the insulated glass unit and extending through the frame,
• wherein the central plane extends through a center of the frame thermal break and forms a common central plane of the building component with substantially equal portions of the frame thermal break extending on each side of the common central plane when the building component is in a closed position,
• wherein the frame thermal break has a width of at least 1 inch, and wherein the pocket has a width that is less than the width of the frame thermal break,
• wherein the insulated glass unit is connected to the frame such that the position of the insulated glass unit is fixed relative to the frame.
