Insulated tracks for use with loading dock doors are disclosed herein. In one embodiment, an insulated door track configured in accordance with the present disclosure includes a first insulator, such as a plastic material, applied to a surface of the door track that extends adjacent to the loading dock door in the closed position. A second insulator, such as a radiant barrier comprised of a thin film of a reflective material, such as aluminum, can be applied to an opposing surface of the first insulator to prevent or at least reduce radiant energy losses through the track. A gap between the first insulator and the door jamb can be sealed with a third insulator, such as a suitable strip of foam.
