An insulated closure panel for a rolling closure. The panel has a metallic section with an outer wall and side walls, and a thermoplastic section with an inner wall. Both panel sections have male and female hinge sections on their sides. The thermoplastic panel section snaps into the metallic panel section to form a tubular panel with the male hinge sections cooperating to form a male hinge element on one side of the panel and with the female hinge sections cooperating to form a female hinge element on the other side of the panel. The panel can be filled with insulating material. A rolling closure is formed from a plurality of the above panels, the male hinge element of each panel pivotally connected to the female hinge element of an adjacent panel.
