HEAT SHIELD MOISTURE-PROOF UNIT, WALL PANEL, AND EXTERIOR WALL STRUCTURE OF BUILDING

摘要

PROBLEM TO BE SOLVED: To constitute a unit provided with heat shielding and moisture-proofing resistance to be applied to an outer wall structure capable of discharging moisture out of a wall body and preventing dew condensation in a wall body.;SOLUTION: The heat shielding and moisture-proof unit 1 comprises a sheet-like heat shielding reflective material 3 having low emissivity and a ventilation member 2 forming a hollow part 20 between the heat shielding reflector 3 and itself. The ventilation member 2 has an outdoor side ventilation member 22 arranged on an outdoor side of the heat shielding reflection material 3, and an indoor side ventilation member 21 provided on an indoor side of the heat shielding reflection material 3 and made of a sheet material or a plate material having moisture permeability. The heat shielding and moisture-proof unit 1 is loaded together with heat insulating material between adjacent column members.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
