Insulate and Innovate

Johns Manville Mineral Wool Sound and Fire Block insulation provides a powerful (and yet quiet) 2-in-1. The insulation batts are noncombustible and moisture-resistant. The high-density fibers in mineral wool help delay the spread of fire and reduce noise transfer in interior walls and between ceilings and floors. The insulation improves wall assembly STC ratings by up to 10 dB, has a melting point in excess of 2000˚F and is made of durable inorganic glass, which translates into no growth of fungi and no sustaining of vermin. JM mineral wool is also easily cut, installed and fills the entire cavity for maximum performance. It is best used in wood-stud cavities and interior walls and ceilings between floors to deliver noise control.
