Claim Text:
1. A method of attaching an auxiliary pane to a window assembly having a primary window pane and a perimeter frame about a full perimeter of the primary window pane, the perimeter frame including a frame surface oriented perpendicularly to the primary window pane about the full perimeter of the primary window pane, the method comprising: providing a plurality of mounting members, each comprising a first flange and a second flange joined perpendicularly to one another at an apex so as to be substantially L-shaped along a length of the mounting member; securing the first flange of one of the mounting members to the frame surface of the perimeter frame along each side of the perimeter frame using a curable adhesive material; providing a gauge comprising a first gauge surface and a second gauge surface arranged to be fixed relative to the first gauge surface at a prescribed distance; abutting the first gauge surface of the gauge against the primary window pane; before the curable adhesive material has cured, for each mounting member about the full perimeter of the perimeter frame, adjusting the position of the first flange relative to the frame surface of the perimeter frame until the second flange abuts the second gauge surface while the first gauge surface abuts the primary window pane; and magnetically coupling a perimeter edge of the auxiliary pane to the second flanges of the mounting members.
