LOW EMISSIVITY LAMINATE AND MULTI-LAYER GLASS

摘要

To provide a low emissivity coating stack having a low emissivity for heat rays and having high visible light transmittance and near infrared transmittance. A low emissivity coating stack 1 comprising a transparent substrate 2, and a thin film laminate portion 3 having at least a first titanium oxide-containing layer 31 containing an oxide of titanium, a low emissivity metal layer 33 containing silver as the main component and a second titanium oxide-containing layer 34 containing an oxide of titanium formed in this order on the transparent substrate 2, which has a surface resistivity of at most 3.3 ©/–¡ and has a solar heat gain coefficient of at least 0.60 when formed into double glazing glass.
