Abstract
An electromagnetic shielding panel incorporates at least two electroconductive coatings. In two of the panels the coatings are carried on separate sheets of float glass one of the coatings being an anti-abrasive coating is on the outermost surface of the glass in the panel arrangement while the other coating being a relatively soft abrasive-sensitive coating, e.g. silver, is on the innermost of the glass in the panel arrangements. In other panel arrangements the two coatings are located on opposing sides of one glass sheet and in two of the panels a plain sheet of float glass is employed to protect the soft silver coating. In another panel a sheet of glass carrying an anti-abrasive coating is employed. The panels are of the double glazed and the laminated type. This invention utilizes the enhanced capacitive coupling between the two coatings to effectively earth the innermost silver coating by way of the anti-abrasive coating without any direct electrical connection being required to be made to the innermost coating.
