A resilient, insulated door panel for a sliding door includes a resilient core protected by a compliant outer covering with a seal disposed about the perimeter of the panel. The panel has sufficient resilience to recover from an impact that temporarily deforms it, yet has sufficient rigidity to transmit a compressive force needed for effectively setting the seals. Much of the core is filled with air to not only provide effective insulation and resilience, but to also provide an extremely lightweight door panel that can be operated to travel rapidly along an overhead track. Some embodiments include relatively rigid backup plates that provide a solid foundation to which the perimeter seals can be attached. The backup plates are segmented so as not to completely restrict the flexibility of the door panel.

1. A door for at least partially covering a doorway in a wall and being able to recover from an impact, comprising:a resilient core; a flexible covering that at least partially covers the resilient core to comprise a first door panel having a relaxed shape disposed along a plane, wherein the first door panel is able to substantially recover its relaxed shape after the impact causes appreciable distortion in the first door panel, and the first door panel is able to transmit in a direction within the plane a compressive load and do so without appreciable distortion to the first door panel; an actuation system coupled to the first door panel to render the first door panel moveable laterally to the doorway between a doorway blocking position and an unblocking position while inhibiting the first door panel from rotating about a vertical axis; and a plurality of backup plates interposed between the resilient core and the flexible covering, wherein the plurality of backup plates have a rigidity greater than that of the resilient core and the flexible covering.
