Grenzebach has developed a sustainable stone wool production line in response to rising energy costs and growing demand for insulation materials. This line, which uses basalt and dolomite as its primary raw materials, is a testament to our commitment to environmental sustainability. The process begins with melting these stones in a furnace, followed by fiberization using a spinning machine. The fibers are then formed into a continuous fibrous web, which is processed through a curing oven. Finally, the cured product is cut and handled to produce the final boards at the cold end.
