Glass Wool Felt

Glass Wool Felt is a roll material made to meet the needs of large-area laying. In addition to maintaining the characteristics of thermal insulation, it also has excellent shock absorption and sound absorption characteristics, especially for medium and low frequency and various vibration noise. It has a good absorption effect, which is conducive to reducing noise pollution and improving the working environment.

Glass wool consist of fine, long, inorganic fibers bonded together by high temperature binder. These fibers (each of approx. 6 - 7 microns diameter) are distributed to trap millions of tiny pockets of air in it thereby creating it an excellent thermal and acoustic insulation. The light weight of Glass wool also offers significant advantages during transport and installation. In addition, Glass wool is chemically inert and has no impurities such as iron shots, sulphur and chloride. The product is non corrosive to metal and does not support mold grow. It is manufactured from renewable raw materials and is environmental friendly in every stage.

In addition to maintaining the characteristics of thermal insulation, glass wool felt also has excellent shock absorption and sound absorption properties, especially for medium and low frequencies and various vibration noises. It has a good absorption effect, which is conducive to reducing noise pollution and improving the working environment. This material can also be cut arbitrarily according to needs during construction. Glass wool felt with aluminum foil veneer also has strong resistance to thermal radiation. It is an excellent lining material for high-temperature workshops, control rooms, machine room inner walls, compartments and flat roofs.

Characteristics of Glass Wool Felt: 

1. High temperature resistance: Yunsheng industrial high temperature glass wool has advanced production technology, professional production technology of strict quality control, the use of temperature can reach 538℃, fully meet the temperature requirements of high temperature system.  

2. High hydrophobicity: Yunsheng glass wool has high hydrophobicity, which can greatly reduce the possibility of thermal insulation performance and service life reduction caused by water vapor infiltration into glass wool.  

3. Uniform fiber diameter fine toughness: Yunsheng glass wool glass fiber diameter is far less than the national standard, uniform distribution, good thermal insulation performance.  

4. High resilience: glass wool has excellent resilience, the product can be restored to the design thickness.  

5. Good tensile resistance: Yunsheng products have stronger tensile resistance, ensuring that the fiber distribution is even after installation and use, and there will not be insufficient local thickness.  

6. Anti-aging, durability: uniform slender, elastic glass fiber is closely connected with each other, avoiding the sharp decline in deformation accumulation and heat coefficient due to vibration after long-term use, Yunsheng industrial high temperature glass wool has a longer service life than other thermal insulation materials.  

7. Fire resistance: More than 90% of the raw materials of Yunsheng glass wool are natural inorganic minerals, so it has excellent fire resistance and belongs to A1 class non-combustible material.  

8. Non-corrosive: Yunsheng glass wool is weakly alkaline, PH value is 7.5-8.0, non-corrosive and stable and durable product performance.  

9. Environmental performance: Glass wool products have been officially confirmed not to be a possible carcinogen, nor will they pollute the environment.

Glass Wool Felt Advantages:

The centrifugal blown glass wool production process to produce a glass wool roll felt 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.

Glass Wool Felt Application：

Yunsheng Glass Wool Felt goods are made for large laying area. Besides the character of thermal insurance, it also has the performances of shock absorption and acoustical isolation, especially for middle or low frequency sound, which can cancel the noise and improve working and living conditions. This material can be freely cut in construction according the shape required, mainly used in room, noise-canceling system, transportation, refrigerators and household eletric appliances for noise canceling.

• Soundproof and fireproof used for wall and roof

• Heat preservation for steel structure building

• Heat Insulation for wall and roof to save energy.

• For indoor partition wall, and train compartment.

Glass Wool Felt Cautions for Use:

• The glass wool should be placed in a dry and ventilated place to avoid rain during transportation.

• Glass wool should be kept away from open flames, paying special attention to the molten slag at the construction site.
