Abstract
A vacuum insulating glazing unit includes a first glass pane having a thickness Z, and a second glass pane made of prestressed glass having a thickness, Z, where Zis greater than Z(Z>Z) The glazing unit also includes a set of discrete spacers positioned between the first and second glass panes and a hermetically bonding seal sealing the distance between the first and second glass panes over a perimeter. A vacuum of pressure less than 0.1 mbar is created in an internal volume V. A thickness ratio, Z/Z, of the thickness of the first glass pane, Z, to the thickness of the second glass pane, Z, is equal to or greater than 1.30 (Z/Z≥1.30).
