Patent ID: 7323088

Claim:
A method of manufacturing a glazing panel, comprising the steps of: a) taking a glass glazing panel having on one of its surfaces (i) a substantially transparent coating layer comprising one or more layers of silver, said substantially transparent coating layer extending to the periphery of the glazing panel and having a transformable portion, and (ii) an enamel material associated with the transformable portion of the coating layer, said enamel material being adapted to form an opaque band around the periphery of the glazing panel; and b) causing an interaction between the transformable portion of the coating layer and the enamel material associated therewith by heating the glazing panel to a temperature above about 300° C. which renders the transformable portion of the coating substantially non-conductive to electricity; and c) laminating the glazing panel with another glass sheet to form a laminated glazing with the coating layer sandwiched between the two panes of glass of the laminated glazing.
