Johns Manville mineral wool safing insulation is made of inorganic fibers derived from basalt, a volcanic rock. Advanced manufacturing technology ensures consistent product quality, with high-fiber density and low shot content for excellent performance. Mineral wool safing is available plain or faced with a (FSP) scrim reinforced foil-facing vapor retarder on one face. Mineral wool safing is inorganic, noncombustible, moisture resistant, non-deteriorating, and will not mildew or support corrosion.

  • Fire safety - mineral wool safing has a melting point in excess of 2000 deg F
  • Durable and inorganic - JM mineral wool batts do not support growth of fungi, nor do they sustain vermin
