1. Thermal insulation performance: The manufacture of glass wool is first made into fiber through a centrifuge, and then a wool felt-like product produced by the process of sedimentation, curing and cutting. The air holes in the middle of the glass fibers form a natural air layer, which enhances the thermal insulation of the glass itself. Is a very good insulation material. 2. Sound insulation performance: When sound passes through glass wool, the sound energy is converted into heat by the small vibrations of the fiber, which weakens the sound transmission. 3. Fire performance: Because the glass itself is like a crystal, it is a relatively high-temperature-resistant material. The highest temperature can reach 250 ° C, which is suitable for residential use. Types and applications of glass wool: 1. Glass wool roll: The product is widely used in factories, warehouses, freezer rooms, gymnasiums, exhibition centers, breeding and thermal insulation sheds; steel structures and various indoor
