Multiple glazed insulating unit, especially for an aircraft window, with electromagnetic armor

An insulating multiple glazing unit comprising:

• at least two superposed panes of transparent substrate, between which there is interposed at least one gap filled with gas;
• a seal configured to mount said panes at their periphery by which the glazing unit can be built into a structure configured to enclose a space containing instruments susceptible to being disturbed by an electromagnetic field and which has an electromagnetic shielding function;
• at least one continuous electrically conductive transparent thin layer provided on one of the panes,
• wherein the seal is made conductive at least in part to ensure connection of the at least one continuous electrically conductive transparent thin layer to the structure, conductivities of the electrically conductive transparent thin layer and of the seal chosen to ensure continuity of the electromagnetic shielding of the structure,
• wherein the at least one electrically conductive transparent thin layer is constituted by a layer of doped semiconductor, having a thickness between 100 nm and 1000 nm and a surface resistivity of 2 to 40 Ω/□, the layer of doped semiconductor oxide being disposed to cover at least one face of the panes, and
• wherein the layer of doped semiconductor oxide is deposited on at least one face of a transparent thin body of poly(ethylene or terephthalate) integrated as an additional layer in the glazed section.
