More about Mineral Wool Board Insulation

Mineral fibers are manufactured by spinning a molten mixture of rock wool (derived from igneous rocks such as basalt) and slag wool (derived from blast furnace slag from the steel industry) into fine fibers. An atomized binder is sprayed onto the fibers as they settle onto a conveyor belt in layers to form an insulation batt or board which is then conveyed into an oven to cure. Binders are commonly urea phenol-formaldehyde, though some manufacturers offer products that use a formaldehyde-free binder. Manufacturers offer various facers including Kraft paper, foil, glass fiber mat facers, or plastic vapor barriers. Mineral fiber batt and board insulation is a thermal insulation product that has high heat resistance, inherent resistance to fungal, mold, and mildew growth, and is water-repellant. It has a high insulating value and also acts as a good acoustical barrier. Because of its high heat resistance, it is sometimes used as a passive fire barrier.
