PROBLEM TO BE SOLVED: To provide a heat shielding sheet capable of preventing a strength shortage by intrusion of radiation heat into the inside of a house from glass and a temperature rise in a sash structure, by surely shielding heat even in a high temperature flame, by enhancing heat insulation performance by adding a heating expansive sheet to a noncombustible sheet for flame heat and the radiation heat when a fire is caused.SOLUTION: A heat shielding sheet 1 is installed so as to cover an opening part of a building 4. This heat shielding sheet 1 is provided by integrally adding a heating expansive sheet 3 to a surface of a noncombustible sheet 2 formed in a sheet shape and having heat resistance of 200°C or more. 【課題】 火災発生時の火炎熱や輻射熱を不燃シートに加熱膨張性シートを付設することにより断熱性能を高め、高温の火炎であっても確実に遮熱し、ガラスから屋内への輻射熱の侵入やサッシ構造体の温度上昇による強度不足を防止することができる遮熱シートを提供する。【解決手段】 遮熱シート１は、建築物４の開口部を覆うように設置される。この遮熱シート１は、シート状に形成された摂氏２００度以上の耐熱性を有する不燃シート２の表面に加熱膨張性シート３を一体に付設する。【選択図】 図１
