A covering for an architectural opening with improved insulating properties in one embodiment includes face-to-face cellular insulative components defining a fabric with dual layers of cells with the fabric being retractably mounted in a headrail so as to either be rolled about a roller or gathered adjacent to the bottom of the headrail. A first component of the fabric includes a pair of spaced parallel sheets of material interconnected with horizontally-extending flexible vanes so as to define a plurality of horizontally-extending, vertically adjacent cells of generally rectangular cross-sectional configuration. A second component of the fabric is mounted on one sheet of the first component of the fabric so as to form a plurality of vertically adjacent drooping segments of fabric forming a roman-shade appearance. Single or multiple layers of the components can be used with or without the other type of component.

1. A covering for an architectural opening comprising in combination: a headrail; a rotatable roller operably connected to the headrail; anda fabric suspended from the headrail, said fabric including two cellular insulative components, one of said cellular components comprised of a pair of flexible, vertically-extending, parallel sheets interconnected at vertically-spaced locations by a plurality of horizontally-disposed flexible vanes defining a plurality of cells between said sheets and adjacent vanes, wherein at least one of said sheets is uninterrupted along a length of at least one cell, said vanes having a width defining the maximum spacing between said sheets that is less than the spacing between adjacent vanes, and the second of said components comprised of a plurality of vertically-adjacent, horizontally-disposed cells formed from droops of flexible material attached at a first location and at a second location to one of said sheets, said first location being substantially adjacent a first vertically spaced location of one of said vanes and said second location being substantially adjacent a second vertically spaced location of another one of said vanes, said cells in said second component being defined between said first location, said second location, droops of material and said one of said sheets in said first component, and wherein the fabric is capable of being rolled up on the roller. 2. The covering of claim 1 further including a control system for moving said fabric from an extended position wherein it hangs vertically from said headrail and a retracted position closely adjacent to said headrail. 3. The covering of claim 1 wherein said sheets of the first component are sheer fabric. 4. The covering of claim 1 wherein said sheets of the first component are not sheer fabric. 5. The covering of claim 1 further including a metallic coating on a face of at least one of said sheets of the first component. 6. The covering of claim 1 further including a metallic coating on both sheets of said first component. 7. The covering of claim 6 wherein said sheets of the first component have confronting faces and said metallic coating is on said confronting faces. 8. The covering of claim 6 wherein said second insulative component has an insulating R-value in the range of 1-2. 9. The covering of claim 1 wherein each cell in said first component is substantially four inches high and ⅜ inch wide. 10. The covering of claim 1 wherein said first insulative component has an insulating R-value in the range of 1-3. 11. The covering of claim 1 wherein said droops of material in said second component are formed from one continuous sheet of material. 12. The covering of claim 1 wherein said droops of material in said second component are formed from individual strips of said material. 13. The covering of claim 1 wherein said material in said second component is secured to one of said sheets in the first component along vertically-spaced horizontal lines of attachment. 14. The covering of claim 13 wherein said material of the second component is secured to a sheet of the first component with adhesive. 15. A covering for an architectural opening comprising in combination: a headrail; a rotatable roller operably connected to the headrail; anda fabric suspended from the headrail, said fabric comprisinga pair of flexible, vertically-extending, parallel sheets interconnected at vertically spaced locations by a plurality of flexible vanes having a first component secured to one of said sheets,a second component secured to the other of said sheets, andan intermediate portion extending between said sheets, said intermediate portion extending in the range of ⅜ inch to ¾ inch to establish a maximum spacing in that range between said sheets,a plurality of horizontally-disposed cells formed from droops of flexible material attached to one of said sheets at a first location and a second location; whereinat least one of said sheets is uninterrupted along a length between a first vane of said plurality of flexible vanes and a second vane of said plurality of flexible vanes;said first location is substantially adjacent a first vertically spaced location of one of said vanes and said second location is substantially adjacent a second vertically spaced location of another one of said vanes, and wherein the fabric is capable of being rolled up on the roller. 16. The covering of claim 15 wherein each vane is vertically spaced from an adjacent vane in the range of 3.5 to 4.5 inches. 17. The covering of claim 15 further including a third sheet of flexible, vertically-extending material and a second plurality of flexible vanes interconnecting said third sheet to one of said first-mentioned pair of sheets at vertically spaced locations. 18. The covering of claim 17 wherein said second plurality of vanes extend in the range of ⅜ inch to ¾ inch to establish a maximum spacing between the sheets to which they are connected in that range. 19. The covering of claim 17 wherein said second plurality of vanes is substantially aligned with said first mentioned plurality of vanes. 20. The covering of claim 15 wherein said plurality of vanes are elongated and horizontally oriented. 21. The covering of claim 17 wherein said second plurality of vanes are elongated and horizontally oriented. 22.
