What is the difference between rock wool and glass wool felt Many people may have this doubt, what is the relationship between rock wool and glass wool felt?  Why the comparison?  These are more people asking questions, then according to these problems, again know rock wool and glass cotton both thermal insulation material, believe that through the interpretation of this time, such as "glass wool blanket is rock wool" is no longer a problem, rock wool, glass wool blanket is not, of course, are two different heat preservation material, although both belong to the heat preservation material,  But there are some differences in the performance and use of the two materials, which requires a deep understanding of rock wool and glass wool felt.  


First of all, rock wool is also felt like products, called rock wool roll felt, referred to as rock wool felt.  Rock wool its main raw materials is basalt inorganic mineral materials, is also belongs to the inorganic fiber materials, relative to the glass wool, rock wool more good high temperature resistance and weatherability, and belongs to the fire a-class non-combustible material, also can be used as heat insulation, but it is mainly used for sound insulation materials, glass wool is more suitable for the sound-absorbing material, this is the difference between the both, and rock wool in the process of using,  It is easy to produce dust.  


Glass cotton blanket is inorganic glass fiber material, raw materials are mainly glass slag and quartz sand, dolomite and other inorganic materials, in accordance with a certain process formula, after high temperature melting, with fiber technology made of felt like products.  It is especially suitable for the laying of the roof and wall of steel structure buildings. It is used for thermal insulation and sound absorption and noise reduction. It is easy to cut, easy to construction, less dust, relatively speaking, relatively moderate, and generally has advantages than rock wool.  


So rock wool and glass wool blanket are two different materials, the main raw material of rock wool is basalt, glass wool is the main raw material of glass slag and quartz sand, dolomite and other inorganic materials.  In particular, glass wool felt is generally used for the insulation and noise reduction of steel structure plant, because rock wool felt is several times heavier than glass wool felt, not suitable for the laying of steel structure plant roof.  Glass wool felt is a light thermal insulation material, which can greatly reduce the bearing capacity of steel structure buildings, effectively improve the safety factor of steel structure buildings, and excellent thermal insulation performance, effectively reduce noise, greatly reduce energy consumption.
