Method of producing an insulating window treatment

Abstract

A fabric processing method is provided to enhance the thermal performance of window treatments while maintaining their light and sheer decorating value and aesthetic appearance. The method uses heat and pressure to enhance the ability of the fabric to reduce thermal transfer therethrough while preserving overall hand, feel and appearance of the fabrics allowing even sheer fabric window treatments to provide enhanced energy efficiency. The fabric, preferably containing a polymeric component such as polyester or the like, is subjected to pressure and increased temperature to create a material fusion that resists thermal transfer as compared to the unprocessed fabric itself.
