Frame providing restriction of thermal deflection of a vig unit edge

A vacuum insulated glass unit comprising at least two glass sheets separated by a gap between said glass sheets,

• wherein a plurality of support structures are distributed in said gap and wherein said gap is sealed and evacuated,
• wherein the vacuum insulated glass unit moreover comprises elongated profiles extending along and parallel to each their edge of the vacuum insulated glass unit,
• wherein a fixation system fixates the vacuum insulated glass unit to said elongated profiles,
• wherein the elongated profiles and/or the fixation system, is configured so as to allow edges of said vacuum insulated glass unit to thermally deflect in a deflection direction perpendicular to a vacuum insulated glass unit due to a temperature difference between the two glass sheets, and to provide a restriction of said thermal deflection of the edges, so as to reduce the magnitude of the thermal deflection compared to an unrestricted thermal deflection of the edges at said temperature difference, and
• wherein a magnitude of the largest total edge deflection due to the restricted thermal deflection of the edges is configured to be at least 10% less than the unrestricted thermal deflection where said temperature difference of is at least 40° C.
