JM mineral wool batts are made of inorganic fibers derived from basalt, a volcanic rock, and are enhanced with glass fibers. Advanced manufacturing technology ensures consistent product quality, with high-fiber density and low shot content for excellent performance. JM mineral wool batts are inorganic, noncombustible, moisture resistant, non-deteriorating, and will not mildew or support corrosion.

JM Sound & Fire Block® batts are designed to deliver noise control in wood-stud cavities of interior walls and ceilings between floors.

Advantages

• Excellent Acoustical Performance - Lightweight, flexible insulation batts are excellent sound absorbers, efficiently reducing sound transmission. JM mineral wool batts improve the Sound Transmission Class (STC) ratings of interior partition walls and suspended ceilings. The high-density, non-combustible fiber in mineral wool reduces unwanted noise from traveling from room to room, making homes quieter.
• Fire Safety: Mineral wool Sound & Fire Block has a melting point in excess of 2000°F (1093°C).
• Noncombustible
• Durable & Inorganic - JM mineral wool batts do not support growth of fungi, nor do they sustain vermin.
