An article having a sealed layered edge, e.g. an automotive laminate and a
multiple glazed unit includes a pair of glass sheet in a fixed
relationship with one another. A sputtered coating is deposited on a
major surface of one of the sheets and includes at least one combination
of a metal film, e.g. a silver film and a dielectric film.
Discontinuities in the metal film at the marginal edges of the coated
sheet provide voids in the metal film to impede or stop corrosion of the
metal film. The discontinuities include (1) break lines or segments in
the coating, (2) coating thickness variations provided by abrading the
coating and (3) spaced discrete coating areas on the marginal edges of
the coated sheet. The discontinuities may be made in the metal film using
a laser, an abrasive surface, a coating mask and/or coating deletion
techniques.
