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 shaping, 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, a type of artificial inorganic fiber. It is made primarily from natural ores such as quartz sand, limestone, and dolomite, along with some chemical raw materials like soda ash and borax, which are melted into glass. In the molten state, it is blown or spun into fluffy fine fibers, with the fibers intersecting and intertwining in a three-dimensional manner, creating numerous tiny gaps. These gaps can be considered pores. Therefore, glass wool can be regarded as a porous material with excellent thermal insulation and sound absorption properties.


In gymnasiums, workshops, and other large spaces, sound-absorbing panels are commonly used for noise reduction, primarily made with centrifugal glass wool as the sound-absorbing material. These panels can be manufactured in board, column, cone, or other irregular shapes. The interior of the panels is filled with centrifugal glass wool, while the surface is wrapped with a sound-permeable layer. Due to the multiple sound-absorbing surfaces, the panels offer high sound-absorption efficiency.
