ABSTRACT:
A door seal for a room shielded against electromagnetic radiation in which the door leaf is mounted on a door frame and will move between open and closed positions. The door seal is formed of coplanar layered flexible metal sheets. A layer of coplanar seal sheets is attached to the door leaf and arranged end to end around the periphery of the door leaf. A subsequent layer or layers of coplanar sheets are also attached to the door and so arranged over the adjacent layer to cover its seams. The layered sheets on the door leaf are pressed into full contact with the door frame by a conventional seal such as a tubular bladder. The layered sheets are flame sprayed to protect against corrosion and assure a highly conductive surface between layers.
