ABSTRACT:
A border molding strip is placed about the perimeter of an existing window pane. A second pane is then placed upon this border material. A retaining border is then placed to retain the window pane firmly against the border material, thus creating an airtight seal between the existing window pane, the border material and the second window pane. Appropriate adhesive and sealing compounds are applied to insure an airtight seal. Thereafter, the space between the existing window pane and the supplemental pane is purged with dry gas and may be evacuated through an opening exposed under a portion of the retaining means. After the window pane is purged and evacuated, a plug is inserted and the opening in the molding material is closed.
