Document Type and Number:
Japanese Patent JP4944852
Kind Code:
B2
Abstract:
A building material composite sheet with heat-shielding, moisture permeable and water-proof property is provided, the sheet improving on workability and safety by reducing not infrared reflectivity, but only visible light reflection with its moisture permeability, water-proof property and air permeability kept intact so as to restrain the operators from feeling dazzled in the eyes. The present building material composite sheet is provided with a moisture permeable and water-proof inner sheet layer 1 and a heat shielding, outer sheet layer 2 comprising a thermoplastic resin substrate 21, a metallic vapor deposited layer 22 having a lustrous metallic material deposited with a certain thickness and formed on the thermoplastic resin substrate 21; a surface protective layer 23 with heat shielding particles 23b substantially uniformly distributed in a transparent thermoplastic resin base 23a and integrally laminated on a surface of the metallic vapor deposited layer 22; and a number of apertures 24 provided in the heat shielding sheet layer 2 with an interval between them, the moisture permeable and water-proof sheet layer 1 being integrally laminated on the heat shielding sheet layer 2.
