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.

Do You Know What the Use of Glass Wool Insulation Material Is?

  From the present day, we can see that   Glass Wool   insulation material is used in many aspects of daily life. Its thermal insulation properties make it widely used in daily life or work. The most common is that in colder winters, people can use this product to wrap their own water pipes. This can ensure that their water pipes are not frozen, and then the water between them can be kept flowing for as long as possible.  Glass Wool Because of its shearability, glass wool insulation materials can be trimmed according to their own needs, and products of different sizes can be cut and used in different places. For example, in this relatively cold place in the Northeast, people can wrap this product on their own roofs, make their houses adhere to a certain temperature, and fully play the role of heat insulation of this product, bringing comfort and comfort to their lives. convenient. In addition, glass wool insulation materials are also used more locally. With the extensive use of this in

Neoprene vs EPDM: What's the Difference?

  Both neoprene and   EPDM   are materials used in the manufacture of conveyor belt systems. While neoprene is most commonly used in the industry, many companies are turning to EPDM because using it overcomes many of the challenges associated with using neoprene.   What is neoprene? Neoprene is made through the polymerization of chlorine. Characterised by its chemical stability, flexibility over a wide range of temperatures and resistance to degradation, the material was originally intended as a petroleum-based alternative to natural rubber.   Its durability and flexibility make neoprene suitable for a wide range of everyday products - such as sports and medical equipment, technical coverings and sleeves, diving suits and safety gloves - as well as for a variety of outdoor applications - including as hoses, gaskets, seals, and gaskets. -including as hoses, gaskets, seals, coatings and linings.   Huamei  EPDM rubber foams  include semi-closed cell supersoft and supersoft foams; closed c

What Is the Difference Between Extruded Board and Foam Board?

  Extruded plate  (XPS), based on polystyrene resin as raw material, through a special process of continuous extrusion foaming molding hardboard, its internal structure for independent closed bubbles, is one kind has high pressure, water absorption, moisture, breathable, lightweight, corrosion resistance, long service life, low coefficient of thermal conductivity, excellent environmental protection heat preservation material performance. Extruded polystyrene (XPS) insulation board is widely used in wall insulation, flat concrete roof, and steel structure roof insulation, low-temperature storage ground, parking platform, airport runway, highway and other fields of moisture-proof insulation, and control ground frost heave. 1. Excellent and long-lasting thermal insulation The extruded board has a thermal conductivity of 0.028w/MK, which has the characteristics of high thermal resistance and low linear expansion rate. Its thermal conductivity is far lower than other insulation materials su
