Product description

Similar to fiberglass in texture and appearance, mineral wool, an inorganic fiber, will not absorb moisture. Rock and slag wool fibers are dimensionally stable, have high tensile strength, and do not support combustion. There is no significant settling with rock and slag wool as long as it is installed properly. Mineral wool will not support the growth of mildew, mold, or bacteria when tested in accordance with the specifications of the ASTM (ASTM C665).
