Mineral Wool Insulation
JM Mineral Wool (SAFB)
JM Mineral Wool (SAFB) fiber insulations are made from basalt rock and slag. This combination results in a non-combustible, sound attenuation product with a melting point of approximately 2150 F, which gives it excellent fire resistance properties. Mineral wool is a water repellent vapor permeable material. Most commonly installed in wood-stud cavities of interior and exterior walls, basements, ceilings, floors and crawl spaces.
