Rockwool is fabricated from rock but looks and acts like wool, a natural insulator. The most suitable raw materials for Rockwool are limestone and basalt.
The raw material is melted in a furnace, using coke as fuel, at temperatures of around 1300 oC. This molten material is then fiberized by means of water-cooled spinning wheels. These fibers are subsequently coated with a termo-setting binder which, when heat-cured, bonds the fibers into a mat. Finally, the mat is cut into various sizes, either small rigid boards or larger blankets.
Boards and blankets can be produced in arrange of densities and thicknesses. Typical densities vary from 40 to 200 kg/m 3 and thicknesses are usually from 50 to 200 mm. Performed pipe insulation can be made for a range of pipe sizes and, like the boards and blankets, can be given a number of different surface finishes, including aluminium foil and glass closth.
Rockwool products have excellent insulation capabilities at temperatures ranging from -240 oC to +820 oC. Their applications include all types of thermal and acoustic insulation required in power generation, industries, buildings, air management, and fire protection, from roofing to steam piping to walls that reduce sound by 50% and reduce energy costs by up to 70%.
