The process of Rockwool is quite intricate, to ensure its safety and its efficiency. Rockwool is wool that is made of molten rocks. Stones are melted in a cupola furnace at 1500 Degrees Celsius and it is then shaped into the fibre. The artistic factor about Rockwool is that it can be shaped in any possible way needed, enabling it to be used in several different functions. Once the stones are heated and spun into fibre, other chemicals are added to them to enhance their usages, such as thermal conductivity, water repellency, color and softness.
