[China Glass Net] The doors and windows of buildings are the components of the building's peripheral structure. They are sensitive parts of building heat exchange. The energy consumption per unit area is 5-6 times that of the wall. The heat loss of doors and windows accounts for the whole building. More than 40%.
The doors and windows of the building are part of the structure of the building's periphery. It is a sensitive part of the building's heat exchange. The energy consumption per unit area is 5-6 times that of the wall. The heat loss of doors and windows accounts for more than 40% of the entire building. There are three ways to reduce the heat loss of the doors and windows outside the building: the heat transfer loss through the aluminum alloy profile; the second, the radiant heat loss through the glass; and the third, the air convection heat loss through the door and window gap. Therefore, the production of thermal insulation and energy-saving aluminum alloy doors and windows should also be considered from these three aspects.
1. Aluminum alloy profiles Aluminum alloy materials are good conductors of heat, and the thermal conductivity is mostly high. To make the heat-insulating glass, it is necessary to select the profile with the heat-insulated bridge, that is, the passage for the heat conduction of the partition to achieve the purpose of thermal insulation.
2, glass insulation doors and windows need to use insulating glass, because the cavity between the hollow glass is filled with dry, static air, so that the thermal conductivity is greatly reduced, so the insulating glass has excellent heat insulation, sound insulation and frost resistance Condensation performance, commonly used hollow glass glass thickness of 5 ~ 6mm, common cavity thickness of 9mm, 12mm.
3. Sealing materials The sealing glue used for heat insulation and heat insulation doors and windows should be made of weather-resistant rubber. The sealing rubber strips should be made of neoprene products with excellent ozone corrosion resistance and UV aging resistance. Three or more sealing rubbers should be installed for the door and window fan to open the overlapping parts. Article.
