The production of mineral fiber board begins with the selection of raw materials, such as basalt or recycled glass. These materials are melted in a furnace at temperatures exceeding 1,400 degrees Celsius. Once melted, the molten material is extruded and spun into fine fibers, which are then collected and laid down in mats. The mats are compressed and treated with various additives to enhance their properties, such as fire resistance, thermal insulation, and moisture repellency. Finally, the mats are cured and cut into boards of various dimensions for use in construction.
