Characteristics of Heat Insulation and Insulation in Steel Structure Buildings

  Centrifugal glass wool felt is a coil made for large area laying. It not only maintains the characteristics of heat preservation and insulation, but also has excellent characteristics of shock absorption and sound absorption, especially for medium and low frequencies and various kinds of vibration and noise. It is conducive to reducing noise pollution and improving working environment. This material can also be tailored arbitrarily according to the need in construction. It is mainly used in building interior, noise elimination system, transportation, refrigeration equipment and household appliances for shock reduction, sound absorption and noise reduction. The effect is very ideal. Glass wool felt with aluminium foil veneer also has strong heat radiation resistance. It is an excellent lining material for high temperature workshop, control room, machine room wall, partition and flat roof.
  The structure is basically a triangular roof truss system made of cold-formed steel members. After sealing the structural slabs and gypsum boards, light steel members form a very strong "slab-rib structure system", which has a stronger ability to resist earthquake and horizontal loads and is suitable for seismic intensity of more than 8 degrees. Area. Wind resistance: steel structure building has light weight, high strength, good overall rigidity and strong deformation capacity. The building's self-weight is only one fifth of that of the brick-concrete structure. It can withstand the hurricane of 70 meters per second, so that life and property can be effectively protected. Durability: All residential structures of light steel structure are composed of cold-formed thin-walled steel members. Steel frames are made of super-anticorrosive and high strength cold-rolled galvanized sheets, which can effectively avoid the influence of corrosion of steel plates during construction and use, and increase the service life of light steel members. The life of the structure can reach 100 years.
  Insulation: The main insulation material is glass fiber cotton, which has good insulation effect. It can effectively avoid the cold bridge phenomenon of the wall and achieve better thermal insulation effect by using the thermal insulation board of the external wall. The thermal resistance value of R15 thermal insulation cotton about 100 mm thick can be equivalent to that of brick wall about 1 m thick. Sound insulation: Sound insulation effect is an important index for eva1uating residential buildings. All the windows installed in light steel system are insulated by hollow glass, which has good sound insulation effect, and the sound insulation effect is over 40 decibels. The wall composed of light steel keel and gypsum board with heat insulation material can achieve sound insulation effect as high as 60 decibels. Health: Dry construction, reduce environmental pollution caused by waste, steel structure materials can be 100% recycled, most other supporting materials can also be recycled, in line with the current environmental awareness; all materials are green building materials, meet the requirements of the ecological environment, conducive to health. Comfort: Light steel wall adopts high efficiency and energy-saving system, which has breathing function and can adjust indoor air dry and humidity; roof has ventilation function, which can form a flowing air room over the interior of the house, and ensure the ventilation and heat dissipation demand of the interior of the roof. Fast: All dry work construction, not affected by the environmental season. A building of about 300 square meters only needs 5 workers and 30 working days to complete the whole process from foundation to decoration.
  Environmental protection: materials can be 100% recycled, truly green and pollution-free. Centrifugal glass cotton mat is a filament material made of melted glass by centrifugal spraying process with fibrosis spraying thermosetting resin, and then formed by thermal curing. Its bulk density is lighter than that of sheet, it has good resilience, low price and convenient construction.
