Abstract:
The present disclosure relates to a vacuum insulated glazing unit, to the use thereof and to a method of manufacturing such a unit. The vacuum insulated glazing comprises a first glass pane, having a first interior major surface and a first exterior major surface and a second glass pane having a second interior major surface and second exterior major surface, the glass panes being arranged in parallel with said interior major surfaces facing each other. The VIG unit further comprises a low emissivity coating deposited on at least the first interior major surface, an edge region in proximity to the edge of the first glass pane, defined as where none or a reduced part of the low emissivity coating is present, and a side seal comprising a glassy seal material arranged at a minimum separation distance (d1_min) from said low emissivity coating, so that an intermediate part of said edge region between said glassy sealing material and said low emissivity coating is not bonded to said glassy sealing material, or a side seal arranged at a minimum separation distance (d1_min) of at least 1.5 mm, such as at least 2 mm, or such as at least 3 mm from said low emissivity coating.
