ABSTRACT:
A method of protecting a metal layer of a solar reflecting coating on a heat-shrinkable substrate, which are components of a prelaminate for a laminated window, from atmospheric corrosion. The prelaminate is cut partially through its thickness adjacent the edge and when the region of the cut is later exposed to elevated temperature, preferably during the laminating process forming the window, the substrate shrinks to create a channel into which flows plasticized polyvinyl butyral (PVB) to block the edge wall of the coating inward of the channel from the surrounding atmosphere.
