Abstract

A system for improving the heat insulating characteristics of existing wall structures, which wall structures include panels and panel edge supporting frames with pockets in a jamb face thereof receiving an edge of the panels. The system includes an elongated stop element having a base adapted to be secured to the jamb face and extended into the pocket after the existing panel has been removed therefrom. The stop element includes a flange extending outwardly of the jamb face to form a supportive side wall of a new glazing pocket adapted to receive an edge portion of a new insulating type panel. An elongated flange element is adapted to be secured on the existing frame in spaced alignment with the flange of the new stop element to form an opposite side wall for the new glazing pocket for securing the new insulating panel in place.
