Everything on earth (including human beings) has life, and there is the day when life will end. And our daily necessities - doors and windows also have a life span, doors and windows will be aging with the passage of time. Everything on earth (including human beings) has life, and there is the day when life ends. And our daily necessities - doors and windows also have a life span, doors and windows will be aging with the passage of time. Product quality determines the service life of doors and windows, and also determines the happiness index of home life. If the doors and windows are all used as indoor and outdoor viewing windows and decorations, but can not achieve the effect of sound insulation, heat insulation, waterproof, wind and rain - noisy and water leakage, high temperature in summer - indoor very hot, winter cold - north wind howling, what is the use of such doors and windows?
Strong oxidation resistance and corrosion resistance is one of the characteristics of aluminum alloy doors and windows, but the overall effect of doors and windows and the extension of service life need many aspects of cooperation, any link negligence will lead to the reduction of the service life of doors and windows.
Wall thickness of profile
The test results of weatherability, thermal insulation and sound insulation of aluminum alloy door and window frames show that the aluminum profile can be used for 10 years if it reaches the national standard wall thickness of more than 1.4mm and the surface oxidation treatment of profile is more than 10 μ m, and the good service life is as long as 30 years.
Some manufacturers "make huge profits". The use of low-quality aluminum alloy profiles - the material is very thin (less than 1.0), which is easy to cause the overall deformation and sagging of doors and windows, and the service life is very short.
Waterproof and moisture proof
Aluminum alloy doors and windows are made of special materials with water absorption less than 0.1%. Double layer sealing is used between the frames and fans. Excellent sealant strips are installed in the gaps. Drainage holes are set at the appropriate positions of the frame materials. The corners are also formed by mechanical welding. Therefore, the sealing performance of the bridge breaking aluminum doors and windows is excellent, which is impermeable, moisture-proof, sound insulation and heat insulation.
Heat preservation and energy saving
The heat conduction coefficient of the material is 1250 times of that of the aluminum door and window frame.
The heat transfer performance ratio of PVC single glass doors and windows to aluminum single glass doors and windows is 1:2. Therefore, the heat insulation performance of bridge broken aluminum alloy doors and windows with the same area is better than that of ordinary aluminum alloy doors and windows, and energy consumption can be saved by more than 30%.
Sound insulation effect
The sound insulation effect of the broken bridge aluminum doors and windows 6 meters away from the road is equivalent to that of the broken bridge aluminum doors and windows 18 meters away from the road.
Door and window accessories are the heart of doors and windows
The doors and windows in the home will be aging after a long time of use, and the hinge will break, and the relevant hardware accessories (handle, one word lock, etc.) can not be started flexibly, which leads to the door and window not being closed tightly. If you don't use them for a year or two, the quality of the doors and windows will start to get loose. At ordinary times, opening and closing doors and windows are inseparable from accessories. Choosing high-quality aluminum door and window profiles and matching with high-quality door and window accessories can prolong the service life of doors and windows. Therefore, it is better to choose high-quality door and window hardware accessories.
