Abstract An electroconductive multiple glazed unit comprising a plurality of transparent glass panels spaced from one another and sealed around their edges to unite said panels into a substantially rigid structure and provide a hermetically sealed space therebetween. A transparent electroconductive coating on the inner surface of at least one of said glass panels and bus bars bonded to said inner surface of said one of said glass panels and in electrical contact with said electroconductive coating. The bus bars and the electroconductive coating each being composed of material that will break into small particles with breakage of adjacent portions of the coated glass panel and said coated glass panels having a tensile strain in the area occupied by said bus bars in excess of about 2,000 millimicrons per inch.
