Patent ID: 7244325

Claim:
A method of manufacturing an insulating glass unit, the steps comprising: applying a metallized coating to an outer surface of a first polymer film by vacuum deposition or sputter-deposition, the first polymer film being an outer layer of a first and second multilayered film composite comprised of a plurality of layers, an inner surface end an outer surface opposite of the inner surface; adhesively applying a removable masking film over the metallized coating to temporarily protect the metallized coating; laminating the inner surface of the first and second multilayered film composite, to a first surface of a first glass pane and a first surface of a second glass pane, respectively; removing the masking film from the metallized coating on the first glass pane and the second glass pane; removing an outer edge strip of the outer layer of the multilayered film composite such that the outer layer and the metallized coating are removed along the outer edge strip without removing other layers of the multilayered film composite on the first glass pane and the second glass pane; mounting the first glass pane and the second glass pane such that the first surface of the first glass pane and the first surface of the second glass pane are spaced apart and face each other; mounting a spacer between the first glass pane and the second glass pane; and filling a cavity between the first glass plane and the second glass pane with a sealant to form an insulating glass unit.
