What is Rockwool?
Rockwool is made from rock but its features and use is similar to wool. It is natural insulator. The most suitable raw materials for Rockwool are limestone and basalt. The raw materials are melted in the furnace with coke as the fuel at the temperature of about 1300 ° C. The molten raw materials will be made into fibers using the rotating wheel reducing the temperature with water. These fibers will be coated with thermosetting sealants. When being heated, the fibers will be combined into sheet. Then, they will be cut into different size of pieces both small and solid or larger rolls
The produced Rockwool sheets and rolls are in various density and thickness. Normal density is in the range of 40 to 200 kg / m³ and normal thickness is usually in the range of 50 to 200 mm. The insulator previously formed can be used to produce pipes in various sizes and can be coated in many forms including foil, aluminum and fiberglass. The sheets and the rolls are the same. Rockwool products have excellent insulation properties at temperature from -240 ° C to +820 ° C. The benefits include the heat proof and sound proof for all types of sound necessary for the operations of industrial power generation, buildings, air conditioning and fireproof systems from the roof to the steam pipe as well as the walls. It can also reduce noise by 50% and reduce electricity charge up to 70%.
