STRUCTURE OF EXTERNAL WALL OR ROOF HAVING PERMEABLE LAYER FOR REDUCING TRANSMISSION OF RADIATION HEAT AND ACQUISITION OF SOLAR RADIATION HEAT AND EXTERNAL MATERIAL FOR EXTERNAL WALL OR ROOFING MATERIAL

摘要

The present invention, in the outer wall or roof structure of the building, by providing a heat insulating, heat shield performance in the vent layer was a conventional dehumidifying action of the air reflux is expected, without changing the thickness of the insulation, the outer wall or high insulation, heat shield of the roof If good securing performance, do not change the thermal insulation, heat shield performance, as to provide a structure and a packaging material for the outer wall or roof yieumjae of the outer wall or roof that can thin the insulation as compared to the prior art, the outer wall or on the outside of the roof structure in the one with the venting layer (9) between the installing exterior material (11) structures, packaging material 11 and the heat insulating material (7) of one or thermal radiation of both long wavelength components on the surface of the vent layer 9 side of the with respect to it, characterized in that to install the low-radioactive sheet (8, 8a) having a low emission performance. ; Cladding for facades, roofs yieumjae, four nations
