    摘要: A vacuum insulating glazing unit includes a first infrared reflecting coating and a second infrared reflecting coating. A first glass pane has a thickness, Z1, and an energetical absorptance EA1, and bears the first infrared reflecting coating on its outer pane face. A second glass pane has a thickness, Z2, and an energetical absorptance, EA2. A set of discrete spacers is positioned between the glass panes and forms an array having a pitch, λ. An internal volume, V, is defined by the first and second glass panes and the set of discrete spacers, and has a vacuum of absolute pressure of less than 0.1 mbar. The second infrared reflecting coating is borne on a glass pane face that faces the internal volume, V. The first glass pane is thicker than the second glass pane (Z1>Z2), and in that ΔEA≤0.0029 ΔZ2/mm2−0.041 ΔZ/mm+0.6375.
