<p>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.</p> |
