| 20110159236 | A BUILDING MATERIAL COMPOSITE SHEET - A building material composite sheet with 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. A moisture permeable and water-proof inner sheet layer and a heat shielding outer sheet layer including a thermoplastic resin substrate; a metallic vapor deposited layer having a lustrous metallic material deposited with a certain thickness and formed on the thermoplastic resin substrate; a surface protective layer with heat shielding particles substantially uniformly distributed in a transparent thermoplastic resin base and integrally laminated on a surface of the metallic vapor deposited layer; and a number of apertures provided in the heat shielding sheet layer with an interval between them, the moisture permeable and water-proof sheet layer being integrally laminated on the heat shielding sheet layer. | 06-30-2011 |
