In case of fire in a high-rise building fire can be easily spread along the building external walls dramatically if the flame comes out through broken windows. There are a few effective methods to prevent the fire spread at the moment. One is using a fire resistance window, and the other is using a window sprinkler that discharges water to resist flame in case of fire. In this study a window sprinkler which is installed on top of windows and prevents fire by discharging water when its heat-responsive element opens was tested using a large scale furnace in accordance with the standard temperature-time graph. Test result showed that one window sprinkler was able to protect a 2,400 mm wide window from fire for 2 hours and the window backside's temperature locally increased up to $126^{\circ}C$ but kept stable around $100^{\circ}C$ for the test duration.

Recently in Korea, the interest for using window and window-wall in building picks up due to the beauty and utilization of space. But, interior space of the buildings shall be compartmentalized by fire resistance structures in accordance with the Korean building codes to prevent the spread of flame and damage of human life in fire. In case of installing non-insulated glazed window in compartment wall, the flame spread to adjacent space and the damage of human life by radiant heat can occur in fire. On this study, to confirm the risk of radiant heat for non-insulated glazed window in fire, the fire resistance tests were conducted. The temperature rise and heat flux on unexposed space was measured and analyzed.

The full-scale compartment fire tests were carried out to evaluate the characteristics of fire resistance of window material under actual fire conditions. The room size used for full-scale room fire tests was 4 by 3.8 m with 2.4 m high ceiling. The windows with PVC, Aluminum and AL+Wood frame materials were established, sofa and mattress were used as fire sources. The window contained pair glasses with the air between 6 mm glasses. Temperatures at total 32 points in the room were measured to find the temperature distribution in the room fire. It is examined that thermal effects on window frame materials such as charring, distortion, melting, structural collapse, and other effects.
