TRANSPARENT SUBSTRATE PROVIDED WITH STACK OF THIN LAYERS, ITS APPLICATION TO THERMAL INSULATION AND/OR SOLAR CONTROL

摘要

PROBLEM TO BE SOLVED: To provide plate glass suitably used for buildings or vehicles and having excellent appearance with blue reflection light to the eyes in addition to proper characteristics such as the transmittance of solar radiation and thermal insulation.;SOLUTION: In the transparent substrate, more particularly of glass and having multiple thin layers on which a first layer having infrared reflection properties, particularly based on a metal, a second layer having infrared reflection properties, particularly based on metal and a third dielectric material layer are successively deposited, the thickness of the first layer having infrared reflection properties is about 50% to 80%, particularly 55% to 75% and preferably 60 to 70% of that of the second layer having infrared reflection properties. The optical thickness of the second dielectric material layer is above or equal to 110% of the sum of the optical thicknesses of the two other dielectric material layers and preferably about 110 to 120% of said sum.;COPYRIGHT: (C)2006,JPO&NCIPI
