Abstract
A covering for window or doors includes a plurality of vanes mounted horizontally or vertically, the vanes being light in weight and longitudinally rigid. The vanes may be foam filled or may include a vane shell made from a polymer matrix, and in either case may optionally include a decorative fabric covering. In the hollow vane embodiment, the vane shell preferably includes a polymer matrix at least partially enveloping fibers, and in the most preferred embodiment is prepared from a fibrous batt including two different thermoplastic resin fibers, one having a lower melting point than the other. The vane shell is formed by thermally treating the batt to at least partially melt the lower melt fibers to at least partially envelope the higher melt fibers. Alternative embodiments of the invention described herein include the horizontal or vertical mounting of the foam core or hollow vanes, the attachment of sheer fabrics thereto, the use of ribbon or cord tilt control systems for the vanes, and other features which create door or window coverings providing light control, insulation, stacking to the side or top, and the capability for cordless operation when the vanes are used in a horizontal orientation.
