1. A coated fabric article comprising:

  • a single layer of fabric containing between about 10 and 90 weight percent of glass fiber and between 90 and 10 weight percent of a natural or synthetic fiber other than glass;

    said fabric having a weight of between about 1.5 and 5.5 ounces per square yard; and

    a coating substantially completely covering one side of said fabric, said coating comprising a fire-retardant thermoplastic polyvinyl halide composition in a thickness of between about 10 and 60 mils to impart the desired drapability, tailorability and physical properties to the coated fabric;

    such that, when said coated fabric is placed under tension forces and exposed to fire, said glass fiber provides a structure which provides strength to said article and which does not tear apart due to said tension forces when said coating burns, thus providing a barrier to the penetration of flame through the article.
