Abstract
A method of making a vehicle window (e.g., windshield or backlite), wherein the method includes using sandblasting to delete a portion(s) of a coating (one or more layers) in an area which may require high visible light transmission in the resulting window. After a portion of the coating on a first sheet has been removed or deleted via sandblasting, the first sheet is laminated to another sheet via at least a polymer inclusive interlayer. The interlayer may include PVB in certain embodiments. The step of laminating significantly increases the visible transmission of the resulting vehicle window in the area where sandblasting was used to delete the portion of the coating.
