This paper simulates the fire prevention performance of external insulation system with curtain wall based on FDS method. The effect to control flame spread of fire-barrier belt and fire separating element with different width is discussed. The characteristics of temperature distribution on the interior, exterior and intermediate cavity of external insulation system are analyzed and the variability of heat release rate is found. The results prove that fire-barrier belt and fire separating element could effectively inhibit flame spread and growth. The fire prevention performance of external insulation system is strengthened with increasing of setting the width. When the width of fire separating element is 100 mm and fire-barrier belt width is 300 mm, the whole external insulation system has good fire prevention performance, which can be set as basic parameters for the design of fire protection construction with consider the applicability and economical efficiency of actual engineering.
