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.

A method of converting an existing single pane window to a double pane evacuated window installation, said method comprising the steps of: applying one surface of a border molding to an existing window pane using an adhesive sealant applying additional sealant to an opposite surface of said border molding; placing a second pane of preselected window material in contact with said additional sealant on said opposite surface of said border molding; applying a retainer molding which interlocks with said border molding to retain said second pane thereby forming an airtight cavity between said window panes; and evacuating the space between said existing window pane and said second pane of window material to form a preselected state of vacuum therebetween.
