Abstract
Abstract The disclosure embraces a fibrous product comprising amorphous glass fibers and crystallizable mineral fibers wherein the mineral fibers may be formed of fusible rock, slag, basalt rock or fibers formed of blends or mixtures of these materials or crystallizable ceramic fibers and to a method and apparatus for forming or processing blends, composites or laminations of such fibers to produce several composite fibrous end products having various uses such as fire rated acoustical tile and ceiling board, high temperature block and pipe insulations, roofing insulation, form board, fire rated cores for walls and doors, fire rated hardboard and building, pouring and blowing wool insulation.
