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. In alternate embodiments a generally tubular door track is either grasped by a door guide apparatus having a clip, or the guide is slit and a rounded guide rides within the track. A door spring assembly shroud is also provided.
A track assembly for affixing a door to a building structure, which door includes an upright lateral edge and which building structure includes an upright wall, and for reciprocal movement of said door along an upright axis, said track assembly comprising:
