ABSTRACT:
Method and apparatus for converting a single glazed wall structure into a double glazed wall structure. The apparatus comprises a spacer element supportable from the wall structure frame on one side of the existing glazing panel and the element includes a stop surface parallel and facing an edge portion of a second glazing panel to be installed parallel of the first glazing panel. A seal is provided around an edge portion of the second glazing panel in position adjacent the spacing element thereby forming a dead air space between the first and second glazing panels to provide a double glazed wall structure having much improved heat insulating characteristics in comparison to the pre-existing single glazed wall structure.
In accordance with the method of the invention, a spacer element is positioned on one side of the existing glazing panel around the frame and a second glazing panel is then installed in spaced parallel relation with the existing panel adjacent the spacer element. A seal is formed between the first and second glazing panels to provide a sealed air space therebetween with a resulting wall structure having excellent heat insulating characteristics.
