An intermodal container includes a supporting frame having a rectangular base; a first pair of upright posts extending upwardly from the rectangular base; and a first cross-beam coupling the first pair of upright posts. A second pair of upright posts extends upwardly from the rectangular base proximate an opposite end thereof, and a second cross-beam couples the second pair of upright posts. A longitudinally extending connector beam has a first end coupled to the first cross-beam, and a second end coupled to the second cross-beam. The intermodal container further includes a plurality of panels, and each panel is made of fiber reinforced plastic and insulation foam that have been integrally molded together. The panels are coupled to the supporting frame and serve as side walls, end wall, roof, and floor of the container. A method for constructing an intermodal container is also disclosed.
