1. Centrifugal glass wool (also known as: glass fiber cotton, glass insulation cotton, centrifugal glass wool, etc.) generally uses the centrifugal blown glass wool production process to produce rolls or panels with soft texture, fine fibers, good resilience and fire resistance. It can be used to lay veneers such as reinforced aluminum foil, which provides an ideal thermal insulation material for steel structures. 2. Due to its unique production process, there must be some gaps in the interior of the material, with a large number of tiny fiber pores. Everyone knows that this is an excellent sound absorbing material with good sound absorption characteristics.
