Abstract:
A roller assembly includes a frame (16) defining a doorway (14). A rail (32), which includes at least one supporting surface along at least one side of the rail, is secured to the frame (16). At least one roller (38), which is adapted to roll along the supporting surface of the rail (32), has a tire material (68) that contacts the rail (32). A thermal barrier (62, 70, 72, 76, 80) is positioned to inhibit heat transfer from the rail (32) to the tire material (68).
