Abstract
Abstract Sheet vinyl covering material having a moisture permeable backing layer of material such as asbestos felt which is dimensionally stable under varying moisture conditions and resistant to degradation from water. The backing layer is sealed on one side with a layer of vinyl halide-vinylidene halide copolymer which is overlaid with a layer of open cellular foamed resinous material. The sheet vinyl laminate also has a resinous wear layer overlying the foamed layer.
