1. thermal insulation Glass wool felt is a commonly used building insulation material, its good thermal insulation performance has been widely used. Glass wool felt can not only block the flow of hot and cold air, but also reduce the heat transfer coefficient of the wall, so that the indoor temperature remains stable. 2. sound insulation and noise reduction The glass wool felt has a good sound insulation and noise reduction function, which can effectively reduce the transmission and reflection of noise. In the fields of industry, transportation and civil construction, glass wool felt has become a very popular sound insulation material. 3. fire insulation Glass wool felt has good fireproof performance, can effectively avoid the harm of fire. The glass wool felt can still maintain good mechanical properties and stable chemical properties at high temperatures, and at the same time has a good thermal insulation effect on the heat in the building. 4. civil buildings The application of glass wool felt in civil buildings can reduce the loss of indoor hot and cold air, reduce energy consumption, and achieve the purpose of energy saving and emission reduction. Glass wool felt can also play a variety of functions such as sound insulation, fire prevention, and shock prevention, and improve the safety and comfort of buildings. 5. steel structure building Steel structure buildings usually need to lay insulation materials in the wall to achieve the purpose of heat insulation. Glass wool felt has been widely used in steel structure buildings because of its good thermal insulation performance and weather resistance. In summary, glass wool felt as a good building insulation material, has been widely used. In addition to heat preservation and heat insulation, it can also have various functions such as sound insulation, fire prevention, shock resistance and weather resistance, which plays a vital role in the construction and transformation of modern buildings.

Glass wool felt is to meet the needs of large-area laying made of coiled material, in addition to maintaining the characteristics of thermal insulation, but also has a very excellent shock absorption. Sound absorption, glass wool felt with aluminum foil veneer, also has strong heat radiation resistance, is a high temperature workshop, control room, room wall, compartment and flat top good lining material. In particular, it has a good absorption effect on medium and low frequency and various vibration noises, which is conducive to reducing noise pollution and improving the working environment. This material can also be cut arbitrarily according to the needs during construction. It is mainly used for indoor buildings, noise reduction systems, vehicles, refrigeration equipment, and household appliances. The effect is very ideal.

With the improvement of people's living standards, the quiet and comfort of the built environment has been paid more and more attention by the masses. In the building materials market, the new material glass wool has good sound absorption performance, why can it absorb sound? Glass wool using ore as the main raw material, with some chemical raw materials for melting, in the melting state of the use of centrifugal blowing process, blowing into flocculent fine fiber and add environmentally friendly formula binder processing. The fibers cross each other and weave together to form a large number of small pores, which is a typical porous sound-absorbing material. It can be applied to wall panels, ceilings, space sound absorbers, etc. to absorb sound energy in the room and reduce reverberation time, thereby reducing indoor noise. Why can glass wool board absorb sound? The reason why glass wool board can absorb sound is because of the small pores and holes in the glass wool. When sound waves enter the glass wool, sound waves can enter the data along the pores, causing air molecules to oscillate. The viscous resistance of the air and the conflict between the air molecules and the pore wall, the sound energy is converted into heat energy and loss. When there is an air layer behind the glass wool, it is similar to the sound absorption effect of the glass wool board with the same thickness without an air layer. In particular, the low-frequency sound absorption performance will be greatly improved compared with the actual hard board, and the sound absorption coefficient will increase with the increase of the thickness of the air layer. Glass wool is used for all kinds of sound-absorbing materials: space sound-absorbing body, composite perforated sound-absorbing board, inorganic fiber spraying, fabric sound-absorbing board (soft bag), anti-collision sound-absorbing cotton (anti-collision soft bag), sound-absorbing glass fiber ceiling, glass fiber sound-absorbing cotton and various sound-absorbing boards. All kinds of sound-absorbing and vibration-absorbing materials: sound-absorbing filling cotton, sound-insulating door, sound-insulating wall, sound-insulating cabinet and other sound-insulating material, sound-insulating structure performance of sound-insulating structure. Glass wool without slag ball, will not destroy the uniform continuity of the fiber structure, so the sound insulation performance is better, for users to create a private, quiet and comfortable space.
