In this study, we have examined the possibility of fire spread by the extruded polystyrene on the external wall of construction site. Through burn pattern tests, it was confirmed that the polystyrene could be difficult to burn continuously without the adhesives and that the mechanisms of combustion reactions how the adhesives were applied. In Limited Oxygen Index test, the oxygen index of organic adhesive appeared at 19%, and total amount of heat release of the organic adhesive was appeared as 75.29MJ/㎡, which was 16.68MJ/㎡ more than that of the inorganic adhesive, and the persistence of heat release rate of organic adhesive was 162s longer than that of the inorganic adhesive in cone-calorimeter test. As the results of these tests, the potential of fire spread by extruded polystyrene alone or with inorganic adhesive were lower than it with organic adhesive. In addition, there would be high risk of fire spread depending on the method of application of organic adhesive for the extrude polystyrene.
