          2020-03-05 06:30:08

          One, the function of door window


          Doors Windows open areas of the building envelope, resist the wind rain of dust, heat, sound, building light environment is extremely important for physical properties of functional components, is indoor environment building facade twofold adornment effect is directly related to the use of construction safety, comfort, energy conservation the improvement of people's living standards.


          It must have the daylighting, ventilated, weather, heat preservation, heat insulation, sound insulation, dust, insects, fire prevention, guard against theft, other functions, can provide a safe comfortable interior living environment for people, at the same time as part of the building exterior interior decoration, its structure, material texture, surface color, such as appearance, the building of the beautiful coordination plays a very important function adornment effect.


          Two, the relevant definition of aluminum alloy doors Windows


          Heat insulation material: a nonmetallic material with low thermal conductivity used to connect aluminum profiles


          Thermal conductivity of the heat insulation strip (W/m2·k) : 0.3


          Thermal conductivity of aluminum alloy (W/m2·k) : 207


          The service life of heat insulation strip aluminum alloy profile is 20 years


          Thermal insulation profiles are divided into perforated poured


          Strip-through: through the opening of teeth, strip-through, rolling process, the strip-type heat insulation material into the aluminum alloy profile into the groove, make it aluminum alloy profile firmly bite the composite way


          Pouring type: the liquid heat insulation material is injected into the aluminum alloy profile casting groove solidified, the temporary connection bridge in the aluminum alloy profile casting groove is cut off to disconnect the metal connection, the two parts of the aluminum alloy profile are combined together by the heat insulation material


          Heat insulation profiles: a composite profile with heat insulation function made by connecting aluminum profiles with heat insulation materials


          Aluminium alloy window: the window that makes frame, fan structure by aluminium alloy building profile


          Aluminium alloy door: the door that makes frame, fan structure by aluminium alloy building profile


          Outer window: a window facing the outside


          Outer door: a door facing the outside


          Flat door: door hinged to the side, inward, outward of a door


          Sliding door: a door with a single, double, multiple sliding doors


          Sash: door hinged to the side, inward, outward of a window


          Overhanging window: a window whose hinges are mounted on the upper side of a window open inward outward


          Underhanging window: a window whose hinges are mounted on the underside of a window open inward outward


          French window: a long window leading to the ground


          Shutter: a window made up of many sheets


          Ribbon window: a continuous horizontal combination of Windows
