ABSTRACT:
A base member and a fascia are assembled to form a hollow door section which is filled with insulative material. Adjacent sections are coupled along respective longitudinal edges for angular and spatial displacement. The base member is extended from a selected plastic with male and female coupling components extending continuously along respective longitudinal edges. A plurality of mounting members projecting from the lateral edges of the sections matingly and slidably engage the semi-cylindrical guide surface of a tract for reciprocal vertical movement of the door. The door may be partially raised for spatial displacement of the sections whereby flow-through ventilation openings are exposed. In a specific embodiment, a flexible drive screw is rotatably carried within the track for powered operation of the door.
