Description
Glass wool insulation blanket is an inorganic fiber roll material designed for large-scale installation. It is made from natural minerals such as quartz sand and limestone, which are melted and then fiberized via a centrifugal spraying process. Its surface can also be finished with aluminum foil for enhanced performance.
The porous structure of glass wool roll felt delivers thermal insulation, sound absorption, noise reduction, and vibration damping properties.

Product Advantages and Applications
1. Glass wool felt is a roll material designed for large-scale installation. Besides maintaining its thermal insulation properties, it also offers excellent vibration and sound absorption properties, particularly effective at absorbing mid- and low-frequency vibrations and various types of noise, helping to reduce noise pollution and improve the working environment.
2. This material can be tailored to meet specific needs during construction. It is primarily used for vibration, sound absorption, and noise reduction in building interiors, muffler systems, vehicles, refrigeration equipment, and household appliances, achieving excellent results.
3. Glass wool felt with an aluminum foil coating also offers strong resistance to thermal radiation, making it ideal for lining high-temperature workshops, control rooms, machine rooms, interior walls, compartments, and flat ceilings.
