In this study, the relationship between the temperature-rise tendencies and properties of mineral wool was analyzed for cases of mineral wool being used as a filler inside insulated fire doors installed in the evacuation space of apartments. The density and thickness of the mineral wool were separately analyzed; as a result, it was found that the higher the density and the greater the thickness, the more suppressed the temperature rise. However, the difference in the rising temperature between the highest density (150 kg/m 3 ) and lowest density (100 kg/m 3 ) mineral wools was 10 K, which did not appear to be significant. The temperature difference between the highest thickness (60 mm) and lowest thickness (45 mm) mineral wools was 60 K, indicating that the temperature rise was more affected by the thickness than the density of the mineral wool. In addition, it was suggested that the performance tests of fire doors, which are currently performed on both sides of a door in accordance with the fire resistance test method, are performed twice on the side from which the door is pulled, which corresponds with the direction in which insulated fire doors are actually installed.
