heat insulation noise reduction fiberglass wool

heat insulation noise reduction fiberglass wool
Huamei energy saving technology group is located in the central zone of Beijing-Tianjin-Hebei Province. It is a large enterprise group integrating r&d, production and sales. It has seven branches and ten production plants in four provinces of China, specializing in the production of rubber foam insulation materials, glass wool products, extrusion polystyrene insulation board (XPS) and other thermal insulation products. HUAMEI rubber foam products pass ISO, ASTM, KS, BS, FM, SGS ROHS and other international standard certificates. Huamei glass wool has passed CE, ASTM and BS international standards test certificates.Perfect production system and quality inspection system to ensure product quality and timely delivery.
Owing to glass wool' good performances,e.g., thin and long inner fiber, low thermal conductivity, it can stop air flowing and heat transforming, Meanwhile, it can quickly reduce the transportation of sound to make effects of insulation and sound-absorption.
Centrifugal glass wool is divided into glass wool boards and blanket. It was the best material used for the insulation and sound absorption of steel structures. It mainly includes bare blanket and blanket with foil-clad covered. They are widely used in industrial plants, warehouses, public facilities, exhibition centers, shopping centers, cold stores and a variety of indoor playgrounds, sports grounds and other buildings.
Product Description
Glass wool board is processed by putting the thermosetting binder into the glass wool, by pressing and heating, and then, by curing.
They are widely used for insulation, ventilation and the adjustment of air-conditioner in commercial industry and residential constructions.
Meanwhile, they have the effect of energy-saving insulating, sound-controlling and improving the indoor air quality.

Demand For Glass Wool In The Market

Glass Wool  has good molding, low thermal conductivity, thermal insulation, and good attraction. It is widely used in building insulation. It is used for thermal insulation, sound absorption and noise reduction of industrial buildings, warehouses, public facilities, exhibition centers, shopping malls, and various indoor playgrounds, sports venues and other buildings. Glass Wool Glass wool insulation materials are also very helpful for building energy saving. With statistics, glass wool can achieve energy saving rate of 55%. Glass wool is based on the principles of vacuum insulation and microporous insulation. Using glass fiber as the core material, the thermal conductivity can reach 0.036W / (mK) or less. The thermal insulation performance is 6 to 10 times that of traditional thermal insulation materials. Products from raw materials collection to the entire production process are combined with environmental protection requirements, non-toxic and harmless; not only can ...

Glass Wool Solves Noise Pollution

  The development of society requires the advancement of many things, and every time something useful is researched, society will make a small step forward. What kind of role a product plays has a great impact on us, and our lives also need their help. Many people literally understand  Glass Wool  as a kind of cotton, in fact, it is an artificial inorganic fiber, which belongs to glass. So which features are more helpful to us? In fact, different functions can play a role in different places. The main thing of glass wool is its sound absorption function. The noise problem is a problem that will occur in many cities now. Therefore, in order to solve these noise pollutions, people have also researched various sound insulation materials, such as glass wool,  Glass Wool Pipe , etc. Especially now that there are more and more cars, no matter whether it is day or night, there are many whistle sounds. At this time, I went to install some sound-absorbing materials on the roa...

Introduction to Glass Wool(Part 2)

  The sound absorption performance of centrifugal   glass wool  is also closely related to the installation conditions. When there is an air layer behind the glass wool board, the sound absorption effect is similar to that of a glass wool board with the same thickness without an air layer. In particular, the sound absorption performance of medium and low frequency will be greatly improved than the material is attached to the hard bottom surface. The sound absorption coefficient will increase with the increase of the thickness of the air layer, but the effect will not be obvious after increasing to a certain value. Using glass wool of different bulk density is stacked together to form a form of gradually increasing bulk density, which can obtain a greater sound absorption effect. For example, stacking a 2.5cm thick 24kg/m3 cotton board with a 2.5cm thick 32kg/m3 cotton board will have better sound absorption than a 5cm thick 32kg/m3 cotton board. The 24kg/m3 glass wool boa...
