FIELD: glass.
SUBSTANCE: invention relates to the field of vacuum double-glazed windows. Article in form of vacuum double-glazed unit comprises first glass sheet; second glass sheet located opposite it; a sealing structure arranged between the first glass sheet and the second glass sheet and intended for tight connection of the first glass sheet and the second glass sheet to form a vacuum chamber; spacers located in vacuum chamber and intended for resistance to pressure of first glass sheet and second glass sheet. Sealing structure comprises metal layers, respectively fixed on opposite surfaces of first glass sheet and second glass sheet, and an intermediate solder layer connecting two metal layers. sealing structure contains arched transition elements in the glass sheets angles areas.
EFFECT: technical result is providing more uniform heating of solder strip in angles regions.
