PROBLEM TO BE SOLVED: To provide a fire protection sash which prevents fire from spreading in a case of fire in a manner that a door roller becomes wrapped while a flow of a melted door roller into an indoor side or an outdoor side becomes suppressed in order to suppress an ignition.SOLUTION: The fire protection sash comprises a frame body installed on a building opening part, and a sliding door which has a resin door roller a on a bottom rail 32 and is openably/closably arranged in the frame body. A thermally expandable material f which expands toward the door roller a of the bottom rail 32 of the sliding door in a case of fire is provided on both side positions of a traveling direction of the door roller a.SELECTED DRAWING: Figure 6
【課題】火災時において、熔融した戸車が室内側もしくは室外側に流れ込むことを抑制しながら、戸車を包み込んで着火を抑制し、延焼を防ぐ。【解決手段】建物開口部に配置される枠体と、下框３２に樹脂製の戸車ａを有し枠体内に開閉自在に配置される障子を備え、障子の下框３２の戸車ａの走行方向両側位置には、火災時に戸車ａに向かって膨張する加熱膨張材ｆが設けられている。【選択図】図６
