Abstract
Abstract A supplemental window and blind unit (10) adapted to be installed in a conventional window (13, 15) having a conventional frame (11) and an original window pane (26). A supplemental frame (28) is attached to the conventional frame (11), and a sash (36) is attached to the supplemental frame (28) in hinged relation. A supplemental window pane (34) is mounted in the sash (36) to close the framed window opening (29) defined by the supplemental frame (28). A window blind (46) is attached to a selected part of the sash (36) so that the window blind (46) is between the supplemental window pane (34) and the original window pane (26) when the sash (36) is in its closed position, whereby the conventional window (13, 15) may be modified to be a window having multiple panes with a window blind enclosed between two of the panes.
