Are rock and slag wool insulation products safe to use?

As with any product capable of producing airborne dust, concerns regarding the health and safety effects of rock and slag wool are understandable. However, few materials have been studied as extensively as mineral wool. The weight of scientific research confirms that these materials are safe to manufacture, install and use when manufacturers' recommended work practices are followed.

Health and safety research on rock and slag wool has been ongoing for nearly 60 years. NAIMA member companies have invested tens of millions of dollars in research projects with leading independent laboratories and universities in the United States and abroad. This research has been designed to investigate the possible human health effects of rock and slag wool as well as other MMVFs.
