Glass wool is a product made by using the exclusive patented centrifugal process technology of Owens Corning (abbreviated as OC) to fiberize molten glass and bond it with an environmentally friendly adhesive mainly consisting of thermosetting resin. It is an elastic felt composed of glass fibers with diameters only a few micrometers, and it can be compounded online with different moisture-proof coatings based on application requirements. Its numerous tiny air pores provide insulation, heat preservation, noise absorption, and safety protection, making it suitable for the thermal insulation and noise reduction in steel structure buildings.
Glass wool is a category of glass fiber, an artificial inorganic fiber. It is primarily made 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 a three-dimensional crisscross pattern, intertwining the fibers together and creating many small gaps. These gaps can be considered as pores. Thus, glass wool can be regarded as a porous material with excellent thermal insulation and sound absorption properties.
