Frame providing restriction of thermal deflection of a VIG unit edge

A vacuum insulated glass unit frame assembly, wherein said vacuum insulated glass unit frame assembly comprises:

• a rectangular vacuum insulated glass unit comprising 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
• a frame arrangement comprising elongated frame profile arrangements which frames said vacuum insulated glass unit in a frame opening extending in a frame opening plane defined between the elongated frame profile arrangements, and wherein said frame arrangement comprises a fixation system fixating the vacuum insulated glass unit at the frame arrangement,
• wherein said frame is arranged so as to allow edges of said vacuum insulated glass unit to thermally deflect in a deflection direction perpendicular to said frame opening plane 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 the largest total edge deflection in said deflection direction of any of the edges of the vacuum insulated glass unit at a temperature difference between the two glass sheets of 65° C. as compared to the vacuum insulated glass unit at a temperature difference of 0° C. is at least 0.3% of the length of the deflecting edge.
