A two way, double action insulating door is described having an insulating core to which is mounted a pair of structural panels. An extruded edge rail is mounted to each edge margin of the core and retains a peripherally-projecting rubber leaf gasket. Preferably the gasket is of a T-shaped cross section and is retained within a slotted edging mounted to the periphery of the door. The door is provided with durable panels covering its exterior faces and also overlaying portions of the edge rail at the edge margins of the door. Optional window assemblies and kick panels are also provided.
