Description

Technical Field

[0002] Fireproof windows need to meet certain requirements of fire resistance stability and integrity. They are used in buildings to isolate and prevent the spread of fire in the event of a fire. Existing fireproof windows are generally composed of steel window frames, steel window sashes, and fireproof glass. In the event of a fire, they rely on their own structure to block the fire and isolate the smoke. Since the window cannot be cooled in time, its fire resistance time is short. In the event of a fire, the heat conduction is faster, the window temperature will rise rapidly, causing deformation and losing the function of isolating and preventing the spread of fire and smoke. Utility Model Content
