The combustion characteristics of roof 'Jucsim' structure was analysed using real scale fire test on wooden structure heritage building. the fire test model was made to consider roof timberling internal structure for a Sunglemun. Structure of test body layed lime, soil, 'Jucsin' and ceiling board excepting roof tile to find heat propagation process by setting thermocouples. The first test to find fire growth and heat propagation process in the part of ceiling. The second test organized to find the efficiency of fire proof paint between ceiling board and inside of Jucsim structure. The third test try to get the performance level of fire proof fabric with the same manner. The result showed from the test proof the heavy smoke exposure with limited effect of fire proof paint however, reliable fire resistance effect showed in case of fire proof fabric.

This study examines the isolation-heat performance of fire proof fabric that is equipped over ceiling board in order to secure the capability of arresting the spread of a fire at roof 'Jucsim' structure of Wooden Cultural Properties. For this examination, I conduct experiments with the model and compare two construction methods of fire proof fabric, or flat-type, folding-type. The experiments show the following results. In case of installing the fire proof fabric in flat-type, when the temperature under the ceiling board is $750^{\circ}C$, the temperatures over the ceiling board is $50^{\circ}C$; the difference is $700^{\circ}C$. Compared with the case of removing fire proof fabric, the temperature over the ceiling board is lower by approximately $580^{\circ}C{\sim}600^{\circ}C$. Therefore it can be said that the construction of fire proof fabric enhances the isolation-heat performance. In case of installing the fire proof fabric in folding-type, when the temperature under the ceiling board is $600^{\circ}C$, the temperatures over the ceiling board is $65^{\circ}C$; the difference is approximately $530^{\circ}C$. Thus its isolation-heat performance is a little inferior to the flat-type equipment.
