A garage door has a multiplicity of transversely extending panels with a preformed core of synthetic resin and integrally formed metallic front and rear skins of the same configuration but reversed. The front skin has its top edge portion configured with an inwardly and then upwardly extending wall portion to define a shelf-like recess adjacent the front face, a generally horizontal top wall portion and a depending lip portion. The bottom edge portion of the outer skin is configured with a generally U-shaped portion extending downwardly from the core and configured and dimensioned to be received within the shelf-like recess of the next lower panel, a generally horizontal portion, and an upwardly extending lip portion. The core has its top edge formed with a shelf-like recess adjacent its front face and a channel-like recess spaced rearwardly therefrom, and the bottom edge has a shelf-like recess adjacent its rear face and a channel-like recess spaced forwardly therefrom. The depending lip portions on the upper edge portions of the skins extend into the channel-like recess in the top edges of the core and the upwardly extending lip portions on the bottom edge portions of the skins extending into the channel-like recess on the bottom edge of the core. Insulating spacer elements may be provided in the channel-like recesses between the lip portions, and hinges hingedly connect the panels.
