A DOUBLE-GLAZED WINDOW STRUCTURE ABSTRACT OF THE DISCLOSURE A structure for constructing a double-glazed window by attaching an add-on outer window frame to the exterior surface of an existing window opening having a ready-built inner window frame is provided, in which an intermediate frame is connected to the inboard periphery of the outer window frame to enter the window opening closely reaching the outboard periphery of the ready-built inner window frame and a gap between the intermediate frame and the ready-built inner window frame is filled by a sealing material to form a joint. The invention is particularly useful in the art of remodelling of single glazed windows into a double glaze window structure in order to increase the insulating property of the window. The improvement is in a substantially increased accuracy of the sealing engagement between the respective window sections.
