PURPOSE: A curtain wall bar having an exterior insulation structure is provided to improve durability by preventing exterior and insulating members from becoming separated from the curtain wall bar. CONSTITUTION: A curtain wall bar having an exterior insulation structure comprises exterior insulating covers(50,60) and an insulating cover(70) for a knob bar. The exterior insulating covers are assembled in the curtain wall bar having a knob bar(40) and surround the outer surface of the curtain wall bar. The exterior insulating covers prevent internal heat energy from flowing out to the outside. The insulating cover integrally surrounds the front panel(30) of the curtain wall bar and both surfaces of the knob bar.
