This paper studies the fire-retardant effect of vertical fire barrier under wind conditions.With extruded polystyrene foam(XPS)used as thermal insulation material of the external wall and rock wool as vertical fire barrier material,a medium-sized wall fire test was carried out to analyze the influence of wind direction,wind speed and barrier width on the wall fire spread characteristics.The results show that vertical fire barriers have good performance under wind conditions.When the wind speed is 1.5 m·s-1,8 cm-wide vertical fire barrier can effectively prevent fire.When the wind speed increases to 2.5 m·s-1,12 cm-wide vertical fire barrier can effectively prevent fire under wind directions of 0,30 and 90 degrees.
