ABSTRACT:
The trim includes a fireproof profiled element (11) of incombustible material, preferably steel, with an L-shaped cross section having a first limb (11a) fixed to a jamb (1, 2) or transom (3) of the door frame and a second limb (11b) located adjacent the corresponding side or face (4-6) of the door opening. In front of the fireproof element (11) is a profiled cover element (14) having a channel-shaped cross section which has a first limb (14a) which bears against the jamb (1, 2) or transom (3) of the door frame and a second limb (14b) force-fitted between the second limb (11b) of the fireproof element (11) and the associated face (4-6) of the door opening. Fixing devices (15) clamp the second limbs (14b) of the cover elements (14) against the associated faces (4-6) of the door opening.
