The present invention relates to a fireproof roll screen which is installed in an outer wall window of a high-rise building to prevent a fire from spreading to the inside of the entire building due to the time lag until fire extinguishing, thereby protecting life and properties from the fire. The fireproof roll screen comprises: a cover which is fixed to the wall surface of a balcony or a sash; a shaft which winds a screen part treated with a flame retardant on the cover; guide rails which guide the movement of the screen part; and a roll screen bar which is installed in the bottom end of the screen part. |
