Abstract
A door assembly comprising a non-rigid door panel which is selectively moved to open and close an opening, the opening having a perimeter defined by opposed first and second sides, a top and a bottom. The door panel includes a first frame member positioned proximate and extending along at least a portion of the perimeter of the opening and a second frame member spaced apart from and co-aligned with the first frame member to define a through-way for passage of a margin of the door panel therethrough. At least a portion of at least one of either the first frame member or the second frame member includes a movable member that pushes the door panel toward at least a portion of the other of the first or second frame members when the door panel is in the through-way thereby sealing the margin of the door.
