Abstract:
A vacuum insulating glazing unit comprising a planar area, first and second glass panes, k discrete spacers distributed over the planar area and positioned between the first and second glass panes, wherein k∈ and k>8, and a peripheral bonding seal hermetically sealing the distance between the first and second glass panes defining an internal volume under vacuum, enclosed between the first and second glass panes and bounded by an inner perimeter of the peripheral bonding seal defining the planar area. The inner perimeter has a substantially rectangular geometry with a length, L, a width, W, with L≥W. The discrete spacers are arranged according to the stress field lines of the combination of atmospheric pressure stresses, σp, applied by the atmospheric pressure on the surface of the vacuum insulating glazing, and of thermal stresses, σt, resulting from a temperature difference between exterior and interior environments.
