<P>PROBLEM TO BE SOLVED: To solve the problem that construction properties may be deteriorated by increase of costs, deterioration of workability and increase of weight since a conventional waterproof sheet for outside walls of a construction hardly contributes to heat insulation, or does not play roles of the moisture-permeable waterproof sheet if a moisture-permeable waterproof sheet and an aluminum foil are to be integrated for utilizing infrared reflection actions of the aluminum foil or the like. <P>SOLUTION: In a house wrap material, on one side of a moisture-permeable waterproof film, a metal deposition layer and a protection layer are laminated in order and on the other side of the film, cloth is laminated. An infrared reflection factor at a protection layer side is 30% or more in the wavelength of 10 μm and moisture permeability is 0.06 to 0.19 m<SP POS="POST">2</SP>s Pa/μg. <P>COPYRIGHT: (C)2013,JPO&INPIT |
