  • The primary component of rigid mineral wool board is basalt, a natural volcanic material, which gives it its distinct insulating properties. During manufacturing, basalt is melted at high temperatures and then spun into fibers, which are subsequently compressed and formed into rigid boards. This process results in a dense, robust product that exhibits low thermal conductivity, making it an effective insulator.
