Primary Uses or Exposures: The major uses of glass wool are in thermal, electrical, and acoustical insulation, weatherproofing, and filtration media. In 1980, approximately 80% of the glass wool produced for structural insulation was used in houses. Some glass wool fibers (special purpose fibers) are used for high-efficiency air filtration media, and acid battery separators.
