An insulating glazing panel including two glass panes held in spaced apart relation by a peripherally extending assembly including a spacer (including profile lengths, corners and at least one connection) and a first sealant. The two glass panes and the assembly define a first, closed interpane space and a second, open interpane space. A second sealant is provided in the second, open interpane space and coats the assembly. The thickness of the second sealant coating the majority of the spacer's outermost points that are not at a corner or connection position is less than or equal to 1 mm; and the thickness of the second sealant adjacent to the glass panes, measured parallel to the glass panes from the spacer's outermost point level at the majority of the positions that are not a corner or a connection, is more than 1 mm.
