Aluminum alloy doors and windows are not only the most basic configuration of general houses, but also the most important factor affecting daylighting, ventilation and comfort. The materials of aluminum alloy doors and windows can be divided into ordinary aluminum alloy profiles and broken bridge aluminum alloy profiles.
Ordinary aluminum alloy profile
Ordinary aluminum alloy profiles are generally sprayed with anti-corrosion treatment on the surface, and there is no air layer inside and outside. The whole is a conductor, which has fast heat transfer and heat dissipation. The thermal insulation strip has low thermal conductivity, forming a cold and hot broken bridge, thermal insulation and diversified colors.
Broken bridge aluminum alloy profile
Bridge breaking aluminum alloy profile is a new type of heat insulation aluminum profile, which uses the heat insulation strip to separate two layers of aluminum alloy, and uses the characteristics of low thermal conductivity of the heat insulation strip to form cold and hot bridge breaking inside and outside the room, so as to achieve the effect of heat insulation and energy saving. The internal and external colors can be selected arbitrarily, and the shape is beautiful.
Wall thickness of aluminum alloy door and window profiles
The wall thickness of the main stressed parts of the window profile shall not be less than 1.4mm. If the high-rise reaches more than 20 floors, you can choose to increase the thickness of the profile; The wall thickness of the main stressed parts of the door profile shall not be less than 1.8mm, which meets the requirements of the national standard for wind pressure resistance. Single doors and windows with an area of more than 3-4 square meters can be thickened, and columns can be added if they are too large.
Maintenance of aluminum alloy doors and windows
Aluminum alloy doors and windows shall be cleaned regularly during use, and the granular and other sundries inside the frame shall be cleaned in time. If the aluminum alloy doors and windows are contaminated with oil stains and other things that are difficult to clean, do not clean them with strong acid or alkali solution to avoid corrosion caused by damage to the protective film and oxide layer on the surface of the profile.
When opening aluminum alloy doors and windows, the force shall be moderate, and the speed of opening and closing shall be uniform as far as possible. Try to avoid hitting aluminum alloy doors and windows with hard objects or scratching the surface of profiles.
