A WALK-THROUGH TYPE FIRE-LIMITING SCREEN ARRANGEMENT IS DESIGNED FOR SEPARATING AN INTERIOR SPACE OF A BUILDING FOR PREVENTING FIRE FROM PROPAGATING AND ASSISTING FOR REFUGEE TO ESCAPE FROM FIRE. THE ARRANGEMENT INCLUDES A NON-COMBUSTIBLE OR FIRE-PROOF SCREEN (1) DROOPING FROM A CEILING OR A BEAM FOR ISOLATION OF AN INTERIOR SPACE OF A BUILDING. AT LEAST ONE SLIT PORTION (3) IS EXTENDED VERTICALLY DOWN TO THE LOWER END OF THE SCREEN (1) FOR DEFINING A REFUGEE PATH. A PREDETERMINED WIDTH OF CLOSURE FLAP PORTION IS ASSOCIATED WITH THE AT LEAST ONE SLIT FOR CLOSING THE SLIT PORTION (3) WITH A PREDETERMINED OVERLAP BETWEEN THE AT LEAST ONE SLIT PORTION (3) AND THE CLOSURE FLAP PORTION. A MAIN WEIGHT BAR (40) IS HORIZONTALLY FIXED ALONG THE LOWER END OF THE SCREEN (1) EXCEPT FOR THE CLOSURE FLAP PORTION, AND A SUB-WEIGHT BAR (5A, 5B) HORIZONTALLY FIXED ALONG THE LOWER END OF THE CLOSURE FLAP PORTION.
