Study on Fire Resistance of Thin Plastered Exterior Wall Building With Combustible Insulation Material
In order to evaluate the fire performance of existing thin plastered exterior walls of combustible insulation materials,the fire perform-ance of molded polystyrene board(EPS)and rigid foam polyurethane board(PUR)thin plastered exterior walls were compared and analyzed.The results show that the temperature of the level line of the external insulation system of PUR thin plastered exterior wall is not much different from that of the external insulation line of EPS thin plastered exterior wall.The temperature outside and inside the level line of the external in-sulation system of PUR thin plastered exterior wall is higher than that of the external and inside temperature of the external insulation system of EPS thin plastered exterior wall.That is,the combustion performance of molded polystyrene board(EPS)exterior wall is better than that of rigid foam polyurethane board(PUR)thin plaster exterior wall.
