The sandwich panel is commonly used domestically because it's less costly and easier to handle. But fires have frequently occurred in buildings employing sandwich panels, such as the fires in Eecheon cold storage and in Gwangju Pyungdong industrial zone. Sandwich panels with steel plates on their surface prevent fire water from penetrating to the fire source, which makes it difficult to extinguish a fire in a timely manner. Toxic gas generated from some insulation material leads to serious loss of life and property. This study is intended to develop an extinguishing system for sandwich panels, thereby reducing the fire risk. Fire water and volume were determined in the wake of the study on the structure of a sandwich panel extinguishing system, and improvement and testing of the fire characteristics of the sandwich panel. Based on such study and test, a fire model test was conducted. Consequently, the sandwich panel with extinguishing system was proven to have a reduced fire risk, compared to traditional or fire retardant panels.
