Abstract
A method for retrofitting a window by combining the window with a switchable or non-switchable window enhancement. The method includes providing a window comprising at least one relatively transparent viewing pane with first and second opposed viewing surfaces, and optionally a frame portion adapted to support and position the viewing pane(s); providing at least one mounting means adapted for securing the enhancement to the window; and securing a window enhancement to the window with at least one mounting means so that the enhancement overlies at least a portion of the viewing pane, and wherein a gap is produced between the window and the enhancement equal in width to the thickness of the mounting means. The enhancement may be mounted on either the viewing pane itself, or alternately upon the frame portion of the window. If desired, the enhancement may be laminated to a relatively rigid substrate prior to application to the window. The invention is further directed to improved, retrofitted windows produced by the method of the invention.
