Abstract
A new and improved system for improving the heat insulating characteristics of an existing wall structure includes apparatus for providing an additional panel in spaced relation with a first or existing panel of an existing wall structure having a surround for supporting the edges of the panel. A sash including the additional panel is mounted in spaced apart relation with the first panel and includes peripheral elongated frame elements, each having a body with a transverse cross-section that is proportioned to extend generally normal to a face of the sash panel and providing a greatest resistance to longitudinal bending forces applied to the element acting in a direction generally normal to the face. Means is provided for structurally interconnecting the sash panel with the elongated elements of the sash frame and the sash is pivotally mounted in the surround outwardly of the first glazing panel. A new and improved method includes measuring the distance between opposite faces of the surround of the existing wall structure in transverse directions and cutting pairs of elongated sash frame elements to a desired length calculated from the measured distance. The elongated sash frame elements are then interconnected at opposite ends to form a generally rectangular sash frame which is mounted in the surround to pivot about an axis extending between one pair of upstanding faces of the surround. An additional insulating panel is then secured in the sash frame around the edges and the sash is pivotally mounted in the surround between a closed position wherein the panels are in substantially parallel, spaced apart, alignment and an outwardly open position pivoted outwardly away from the existing wall panel so that washing of both panels can be readily accomplished when desired.
