Abstract
An environmental barrier device which fits between an open door of a building and the door jamb in order to enclose the open space therebetween and through which hoses, electrical wires, tubing, piping, etc., may pass. The device allows access to and egress from the building while in use and yet seals the open space against loss of heat or coolant, and also prevents pets, insects, or the like from passing through the open space during the time the door is necessarily open.
