ABSTRACT:
A display glazing which is fitted to a refrigerated display case and which prevents moisture condensation thereon, comprising a shaped glazing having at least a portion of one side thereof provided with a low emissivity coating, conductive current input strips placed on the glazing in contact with the low emissivity coating which define coated zones of the glazing which are heated by the Joule effect upon the passage of electrical current between the conductive strips, and a means for determining if atmospheric conditions are such that condensed moisture is likely to form on the exterior surface of the unheated glazing.
