  • The purpose of this study is to improve the fire prevention performance using the fire venetian blind louver subjected to burning by fire flame. The investigation is based on testing 2 full scale specimens, which is $3m{\times}3m$ module, $850mm{\times}1,500mm$ open, and $900mm{\times}900mm{\times}175mm$ venetian blind louver. Two louver thickness (1.5 and 2.0mm) were adopted. The specimens were exposed to fire flame temperature levels of ISO834 at the lower surface of the fire venetian blind louver specimens with exposure duration of one hour in Korea Institute of Construction Technology (KICT). It was found from the test results that the values of distributed temperature, decreased for all specimens for protecting to fire flame by venetian blind louver. The results of tests were a good fire prevention performance between in initial to 6 mins. At 60 minutes around ISO 834 fire loading, the percentages of distributed temperature in 500mm and 800mm height ranged between 11 and 10% respectively, regardless of louver thickness. This study, therefore, will improve the fire venetian blind louver for fire protection and prevention performance.
