Johns Manville MinWool-1200® 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 in high-temperature and fire resistance applications. JM's Mineral Wool board is inorganic, noncombustible and will not mildew or support corrosion. These high temperature boards are easily fabricated, cutting cleanly and easily with a knife. These product attributes make Mineral Wool Board ideal for commercial appliance, hearth, crematorium and fire protection (e.g, fire door) applications.
Made-to-Order (MTO), Mineral Wool Board can be manufactured to be moisture repellent.
