This invention relates to glazing panels, and in particular to chromogenic glazing panels and to a process for manufacturing such glazing panels. It is disclosed a glazing panel comprising two sheets of glass spaced apart from each other and sealed together along a of their edges, wherein the distance between the two sheets of glass is between 10 and 500 μm and wherein the glazing panel is provided with a plurality of spaced deposits arranged between and in contact with the two sheets of glass and arranged with a distance between the deposits of between 1 and 10 cm, at least some of the deposits being attached to the surface of each glass sheet and each deposit comprising an adhesive. The glazings according to the invention have the advantage of providing a substantially constant distance between the two sheets of glass over substantially the whole surface of the glazing panel.
