Centrifugal glass wool exhibits good sound absorption properties for high frequencies. The main factors affecting the sound absorption performance of centrifugal glass wool are thickness, density, and air flow resistance, among others. Density refers to the weight of the material per cubic meter. Air flow resistance is the ratio of air pressure and air velocity on both sides of the material per unit thickness. Air flow resistance is the most critical factor affecting the sound absorption performance of centrifugal glass wool. Too low flow resistance indicates the material is sparse, making air vibrations easy to pass through, thus reducing the sound absorption performance; conversely, too high flow resistance suggests the material is dense, making it difficult for air vibrations to penetrate, which also decreases the sound absorption performance. For centrifugal glass wool, there is an optimal flow resistance for sound absorption.

Glass wool is a product manufactured using Owens Corning's (abbreviated as OC) proprietary centrifugal spinning technology, which fiberizes molten glass and binds it with an environmentally friendly formula mainly consisting of thermosetting resin. It is an elastic felt made from glass fibers with diameters of just a few micrometers, and it can be compounded with different moisture-proof coatings online as per the application requirements. Its numerous tiny air pores enable it to provide thermal insulation, noise absorption, and safety protection, making it suitable for the thermal insulation and noise reduction of steel structure buildings.

Glass wool is a category of glass fiber, a type of artificial inorganic fiber. It is produced 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, external force is used to blow or spin it into fluffy fine fibers, with the fibers interlocking in a three-dimensional crisscross pattern, creating numerous tiny gaps. These gaps can be considered pores. Thus, glass wool can be regarded as a porous material with excellent thermal insulation and sound absorption properties.
