摘要

The door (4) has external and internal faces (16, 18) opposite with each other. An external metal panel (20) comprises a zone that defines the external face and two side opposites rails (22) integrated to the external face. An interior metal panel (24) with a zone defines the interior face, where the interior face comprises two opposed side edges (51) engaged in the side rails of the external panel. A thermal insulating material layer (28) is interposed between the interior and external faces, where the door is made of wood. An independent claim is also included for a method for assembling a fire door.
