PROBLEM TO BE SOLVED: To obtain a sound-absorptive thermal insulating material which maintains a certain temperature environment and is excellent in heat insulating property, low in heat radiation, and high in sound absorption. SOLUTION: The sound-absorptive heat insulating material with low thermal emissivity, comprises a porous material and a surface facing material covering the porous material. The surface facing material has a fabric structure and a material with low thermal emissivity adheres to the surface of the fabric structure. It is preferred that the surface facing material is formed of glass cloth, that the material with low thermal emissivity is aluminum, and that aluminum is deposited on the glass cloth by sputtering. If needed, a top coat may be applied on the external surface of the adherent metal to the surface of the fabric structure of the surface facing material. |
