In the sound insulation wall, the choice of sound insulation effect of good materials, can ensure the quality of sound insulation, and improve the safety of fire protection, and sound insulation for a long time and effective. A good quiet environment, can let people live when the body and mind relax, no noise interference to spend. So, the material that does sound insulation wall chooses rock wool or glass wool?

　　The material that makes sound insulation wall chooses to fill glass wool, sound insulation effect is better. The raw materials and production methods of the two materials are different. Slag is the main raw material for rock wool, and dolomite is the raw material for filling glass wool. Made of glass cotton fiber is relatively soft and slender, evenly distributed, not easy to loose. The diameter of the rock wool fiber is coarser, which requires higher bulk density and thicker thickness, and is formed by bonding agent. Generally speaking, the capacity of rock wool is heavy, heavy weight and high thickness. In the case of the same density, glass wool because of the stronger structure, the sound absorption coefficient is higher, so that the sound absorption effect is better.

　　If the partition wall is filled with rock wool, for a long time, the rock wool will appear loose phenomenon, lose the sound insulation effect. And the bulk density of more than 32K glass wool will not appear this phenomenon. The sound insulation effect between rock wool and glass wool is about 1.2 times that of glass wool. The two kinds of materials belong to class A fireproof materials and have good fire performance. But the inorganic material fiber is small, if it touches the human skin, there will be pain and itching phenomenon. Therefore, in the installation, should wear protective tools before the operation.

　　Rock wool and glass wool are high temperature resistant, rock wool can withstand 500 degrees, glass wool 300 degrees to 400 degrees. So rock wool is more used in heat insulation and insulation engineering, glass wool is used in sound absorption and sound insulation engineering. For construction projects with higher environmental requirements, glass wool is generally selected as a friendly sound wall filling material.
