Abstract

With the recent strengthening of fire performance standards for building finishing materials, external wall finishing materials for buildings over 3 floors or over 9 m must meet the performance of semi-non-combustible materials and pass the KS F 8414 performance standards. But in the case of buildings under 5 stories or under 22 m, it is stipulated that flammable insulation can be used when the finishing materials satisfy the performance of combustible materials or applies a fire spreading prevention structure. In this study, fire performance was evaluated on two specimens that applied fire spreading prevention structures to combustible and semi-non-combustible materials. And both test specimens satisfied the KS F 8414 performance standards. It is necessary to apply the performance evaluation criteria of KS F 8414 differently depending on the number of floors and height or combustibility of the materials. As the number of floors and heights of some buildings overlapped and applied differently, it is believed that there is a need to subdivide and revise the performance evaluation standards for external wall finishing materials.
