In fact, it is very simple. Glass wool is processed from glass (silicon?dioxide) , while rock wool is made from basalt or diabase through high temperature refining equipment, which are two completely different products. Hope it is helpful.
Glass wool is glass wool roll mat made through fibering of molten glass and then solidification by adding binder, and fibre?diameter of glass wool depends on centrifugation extrusion technology. The difference is the centrifugation techniques, TEL centrifugation technique of Saint-gobain Aesop who is the founder of glass wool, is the most popular technique currently. At present the domestic glass wool market is gradually expanding. Companies such as Quanhe Chemical Co., Ltd. in Dacheng have made significant contributions to promote glass wool. Rock wool board is artificial inorganic fibers made from basalt, and processed through melting in high temperature, with light weight, low heat conductivity coefficient , heat absorption, non-combustible characteristics. The initial development should be consistent with stipulation in Application types and basic requirements of building thermal insulation materials. It is generally used in industrial architectures. Pilot run succeeded in June 198. Rock wool board is new type of thermal insulating, fire retardant and sound absorbing material.
