Yara rock stone wool products are made from natural rock such as basalt and dolomite. The natural rock is melted into melts in cupola at a high temperature about 1500°C. And the melts lava is then pour to high speed spinners through which the melts get into fibers. After that, fibers are collected together to form the original wool mat. The original wool mats then pass through pendulum, crimping and pressing process, get into the curing oven through which the wool mats are cured and shape up to different kinds of products such as rock stone wool board, rock stone wool blanket, rock stone wool pipe section, hydroponic cube, rock stone wool strip etc with different usage.
