Ultra-fine glass wool insulation is primarily made from raw materials such as quartz sand, feldspar, sodium silicate, and boric acid. These components are melted at high temperatures to produce fibers with a diameter of less than 2 micrometers. A thermosetting resin adhesive is then added, and the material is pressed under high temperature to form various shapes like boards, blankets, and pipes. The surface can also be coated with aluminum foil or PVC film for additional protection and performance. This insulation material is lightweight, has low thermal conductivity, high sound absorption, and excellent fire resistance. It is widely used in thermal equipment, HVAC systems, hot and cold piping, ovens, drying rooms, refrigeration units, and building insulation, offering effective heat, sound, and thermal management.
Centrifugal glass wool is a fibrous material created by spinning molten glass using a centrifugal process, combined with a thermosetting resin. After heat curing, it becomes a versatile product suitable for multiple applications. It offers numerous benefits, including flame resistance, non-toxicity, corrosion resistance, low bulk density, minimal thermal conductivity, strong chemical stability, and excellent water repellency. It is considered one of the best materials for thermal insulation, heat retention, and sound absorption. Its versatility has led to widespread use in construction, chemical industries, electronics, power generation, metallurgy, energy, and transportation sectors, providing efficient insulation, noise reduction, and sound control.
Due to its soft texture and fine fibers, centrifugal glass wool does not irritate the skin during installation, making it a preferred choice among construction professionals. Its ease of handling and superior performance have made it a top option for insulation projects across various industries. Whether used in residential or commercial buildings, it delivers reliable results and long-term durability, ensuring comfort and safety in different environments.
