A casing surrounds the longer members and is made of two extruded sections, of synthetic material, which protrude laterally from the metallic frame and are interconnected to each other. The outer casing section carries weather strips for sealingly engaging the outer section of an adjacent panel. The outer casing section also carries retaining strips of J-shaped cross-section, which retain sheathing panes forming the main panel faces. These sheathing panes may be translucent or transparent, or may be opaque to conceal heat-insulating material which fills the panel inner space. Spaced upright mullions are disposed within the door panel and fixed to the horizontal frame members to provide anchors for the hinges which interconnect the panels. | |
