Glass wool is a category of glass fiber, a type of artificial inorganic fiber. It is formed by fiberizing molten glass into a fluffy material, with a chemical composition belonging to the glass family and is an inorganic fiber. It boasts good formability, low bulk density, low thermal conductivity, excellent thermal insulation, good sound absorption, corrosion resistance, and stable chemical properties.

Glass wool is a category of glass fiber, an artificial inorganic fiber. It is made primarily from natural ores such as quartz sand, limestone, and dolomite, along with some chemicals like soda ash and borax, melted into glass. In the molten state, it is blown or spun into fluffy fine fibers, with the fibers crossing and intertwining in a three-dimensional pattern, creating many tiny gaps. These gaps can be considered as pores. Thus, glass wool can be regarded as a porous material with excellent insulation and sound absorption properties.


In gymnasiums, workshops, and other large spaces, sound-absorbing bodies, primarily made of centrifugal glass wool for sound absorption, are commonly used for noise reduction. Sound-absorbing bodies can be manufactured in sheet, columnar, conical, or other irregular shapes to meet specific requirements. They are filled with centrifugal glass wool inside and covered with an acoustically permeable surface layer on the outside. Due to the multiple surfaces for sound absorption, they offer high sound-absorption efficiency.
