Johns Manville MinWool® Sound Attenuation Fire Batt (SAFB) insulation is manufactured from inorganic fibers derived from volcanic rock. Noncombustible and moisture-resistant, the lightweight and flexible batts are designed to deliver excellent noise control in metal-stud wall cavities of interior partitions, exterior walls or above suspended ceiling systems. As excellent sound absorbers, these batts improve the wall assembly Sound Transmission Class (STC) ratings by up to 10dB.
Sound Control: Absorbs sound and improves wall assembly STC ratings by up to 10 dB.
Fire-Resistant: Melting point in excess of 2000˚F (1093˚C). Flame Spread of 0 and Smoke Developed of 0.
Durable Inorganic Glass: No growth of fungi. No sustaining of vermin.
