Mineral wool (re)gains some ground

摘要

Although mineral wool-also referred to as rock wool, slag wool, and stone wool-was one of the first insulation materials to be widely produced commercially (starting back in 1871 in Germany), the product lost most of its market share when less-expensive fiberglass insulation came along. But mineral wool's dense batts, with their high percentage of recycled content, inherent fire resistance, and comparatively high sound control and resistance to airflow, have recently reclaimed some of the residential insulation market. Much of this success is the result of the aggressive distribution of Roxul's ComfortBatt mineral-wool insulation over the last few years.
