A door assembly that includes a a frame having an upper portion and a lower portion, an electrical hinge mounted to the upper portion of the frame, a gravity hinge mounted to the lower portion of the frame and a door pivotably mounted to the frame by the electrical hinge and the gravity hinge. The electrical hinge pin has a hinge pin part having a plurality of electrical conductors extending downwardly therefrom. The gravity hinge also includes a hinge pin part. The door includes a laminated package having first, second and third layers adhered to one another. At least one of the layers includes an electro-conductive coating thereon that is in electrical communication with the electrical hinge. The door also includes a rail secured adjacent a hinge side edge of the laminated package. The rail includes a tunnel defined therein that includes a top opening that receives the hinge pin part of the electrical hinge and a bottom opening that receives the hinge pin part of the gravity hinge.
