Ultra-fine glass wool insulation is primarily made from materials such as quartz sand, feldspar, sodium silicate, and boric acid. After being melted at high temperatures, it forms fibers with a diameter of less than 2 micrometers. A thermosetting resin adhesive is then added to press the material under high heat, creating 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 material features a low bulk density, minimal thermal conductivity, high sound absorption, and excellent fire resistance. It is widely used in thermal equipment, HVAC systems, hot and cold piping, drying rooms, refrigeration units, and building insulation for thermal, acoustic, and soundproofing applications.
Centrifugal glass wool is a fibrous material produced by spraying molten glass into fine fibers using a centrifugal spinning process, followed by heat curing to create a range of versatile products. It offers numerous benefits, including flame resistance, non-toxicity, corrosion resistance, low density, low thermal conductivity, strong chemical stability, low moisture absorption, and good water repellency. It is currently considered one of the best materials for thermal insulation, heat retention, and sound absorption. Its applications are extensive, ranging from construction and chemicals to electronics, power generation, metallurgy, energy, and transportation. The boards, blankets, and tubes made from this material have proven highly effective in thermal insulation, noise reduction, and sound absorption.
Due to its soft texture and fine fibers, centrifugal glass wool is gentle on the skin during installation, making it a preferred choice among construction professionals. It has become the top option for insulation due to its comfort, efficiency, and reliability. Whether in industrial settings or residential buildings, its performance and safety make it an essential component in modern insulation solutions. With continuous advancements in manufacturing technology, its versatility and effectiveness continue to grow, ensuring its place as a leading insulation material in the industry.
