The door, with a metal outer sheet (1) between vertical metal side members (2) fitting inside an angle iron framework (9) in an opening in a wall (10), has an insulating layer 83) and a hf screening panel (16) inside. This panel is parallel to the outer sheet and is moved rearwards to engage pairs of contacts (20) inside the door. The panel is flanged, with side flanges (19) extending rearwards, pushed between the contacts when in the engaged position. The contacts are mounted on resilient contact blades (21) housed inside recesses of shaped parts (12) of the frame (12) connected to the angle irons. The screening panel is moved between its two end positions by pneumatic or hydraulic cylinders (18) supported by the outer sheet.
