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.

Advantages

• Dependable Thermal Performance - With high fiber quality and low shot content, JM mineral wool batts deliver consistent thermal insulating performance at the rated R-value. The high-density, non-combustible fiber helps keep homes warm in winter and cool in summer while reducing heating and cooling bills to save money year-round.
• Fire Safety - Mineral wool TempControl 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.
