Good thermal insulation performance is the basic characteristic of thermal insulation rock wool board products. Their thermal conductivity is usually between 0.03 and 0.047W/(moK) at room temperature (about 25°C).

     Thermal insulation rock wool board has excellent sound insulation and sound absorption performance. Its sound absorption mechanism is that this product has a porous structure. When sound waves pass through, friction occurs due to the flow resistance, so that part of the sound energy is absorbed by the fiber. Hinder the transmission of sound waves. It is widely used in shipbuilding, metallurgy, electric power, construction and other industries.Thermal insulation rock wool board is easy to construct and install, it has remarkable energy-saving performance, and  high performance cost.
     Glass wool board has light bulk density, low thermal conductivity, high absorption coefficient and good flame retardant performance. It can be widely used in thermal insulation and sound insulation of thermal equipment, air-conditioning, cold and hot pipes, cold storage, buildings, etc.
     Glass wool board has lower bulk density, less shot content, lower thermal conductivity, longer service life, and greater fiber toughness than thermal insulation rock wool board. However, the maximum use temperature of thermal insulation rock wool board is about 600 degrees Celsius, and glass wool board is only 260 degrees Celsius.
     Above is the introduction of difference between thermal insulation rock wool board and glass wool board. Hope this can bring you some help.
