Patent ID: 7056586

Claim:
A process for manufacturing a laminated glazing unit having at least two panes forming a composite with an inside and an outside, a first coated pane being provided on a surface facing the inside of the composite with a corrosion protected transparent surface coating and at least one adhesive layer for coupling the panes together, the process comprising: removing the transparent surface coating proximate at least one edge of the coated pane to create an exposed region between about 0.1 mm and about 5 mm from a peripheral edge of the pane along a main surface of the pane; applying an opaque protective layer proximate the peripheral edge of the coated pane after removal of the transparent surface coating therefrom, the protective layer being substantially impermeable to diffusion of water vapor and covering at least a portion of the exposed region of the coated pane and extending across a portion of the transparent surface coating beyond an edge thereof proximate the peripheral edge of the pane; coupling the panes together with an adhesive layer disposed therebetween to form the laminated glazing unit.
