Technologies on energy saving and materials used in curtain walls have progressed with increase of high-rise and large buildings. This study is explain fire resistance performance of the curtain walls. And focused on bond strength of light-weight inorganic ceramic board in high temperature for fire resistant curtain-wall system. From the result, curtain-wall system high fire resistant using the light-weight inorganic ceramic board.

This study had the goal of analyzing the economic feasibility and constructability of a fire resistant curtain wall system using Light-weight Inorganic Composite Foam Board(LI-CFB). LI-CFBs, new materials with excellent fire resistance are being developed for use as the back panel of curtain wall and their fire resistance has already been analyzed through actual tests in earlier studies. In this study, a mock-up test involving the installation of the fire resistant curtain wall system on an actual building was conducted, and the system was compared with a common curtain wall system. This system is applied in the same way as a common curtain wall system. But the cutting LI-CFBs, which are brought from a factory, are used in the system and attached on the frame (mullion and transom). Even though the system requires more working time than the existing system, the LI-CFBs back panels are easy to cut and do not produce dust. Also, the panels are able to be assured the quality by checking damaged parts easily. Besides having a high level of fire resistance, the system's economic feasibility and constructability meets or exceeds those of the existing system.

Fireproof structures using concrete, built-up panels and dry walls are usually used in walls inside fire compartments. However, demand for glass walls is emerging due to increase in interest in visibility and external appearance. In this study on steel fire resistance walls using insulation glass, fire resistance tests and performance evaluations were conducted on 60 minute fire resistance walls and exterior walls which could be applied to interior fire compartments and 90 minute fire resistance walls which could be applied to curtain walls. According to the tests, the specimens satisfied the required fire resistance performance. The finite element analysis was conducted after the tests to evaluate the fire resistance performance of the glass walls. The analysis results showed that the preliminary evaluation of fire resistance performance would be feasible.
