1. What are the famous brands of aluminum alloy doors and windows?
At present, there are ten brands of aluminum alloy doors and windows commonly used in the market: Kangying doors and windows, Ma Baili doors and windows, San Milan doors and windows, red oak doors and windows, Fu Xuan doors and windows, Aowei doors and windows, Jin Yue doors and windows, Xinhaoxuan doors and windows, Odik doors and windows and so on. When you buy aluminum alloy doors and windows, you'd better choose products with high brand awareness and good reputation, so that the quality and after-sales service in the later stage of home installation can be guaranteed.
Second, how to choose aluminum alloy doors and windows?
1. Generally, the glass on the window is made of toughened material, so it must be marked with 3C, otherwise it should not be used. Secondly, the thickness of the glass. If it is double-layer glass, the thickness of a single layer is usually 5 mm, and the size of the gap between the two layers of glass is also particular. Many people know that the bigger the gap in the middle, the better the sound insulation effect of the glass.
2. Measure with a ruler: In addition to thickness, there are international and non-standard points. First of all, the thickness of this piece is usually divided into 1.2 and 1.4MM. It is recommended that you use the thickness of1.4 mm, so that the window will be more fixed after installation. Of course, the national standard should be used. If the budget is limited, the national standard 1.2 is ok, but relatively speaking, it is definitely not as good as 1.4. However, it is not recommended to use non-standard configuration files.
3. Check the heat insulation strip: If the selected window is a profile of broken bridge aluminum, then there must be a heat insulation strip. Although seemingly insignificant, it plays a great role, mainly in heat insulation, especially in summer, which can reduce the heat conducted by doors and windows. As for the material, PVC is the most common material on the market, but here we recommend you to use PA material. As for how to distinguish, this is also very simple. Just burn it. PA material is nonflammable, while PVC material not only burns, but also smells like plastic.
4. Splash water to test the waterproof performance to see if water will invade the opposite side: quickly check whether water will flow into the opposite side through one side. If there is, it proves that its waterproof performance is poor, and it is very likely to enter the water in bad weather.
5. Check the welding process of the working angle with a magnifying glass: check whether the welding is even and flat, and whether there are gaps and welding holes.
3. What are the specifications of aluminum alloy doors and windows?
1, aluminum alloy doors and windows specifications and standards
There are 70 series and 90 series aluminum alloy sliding doors, and 70 series aluminum alloy sliding doors can be used in houses. The serial number indicates the millimeter of the structural dimension of the door frame thickness. There are 55 series, 70 series, 80 series, 90 series, 109 series, 120 series and 130 series of aluminum alloy sliding windows. Series selection should be based on window size and local wind pressure value. Aluminum alloy sliding windows used as closed balconies should not be less than 70 series.
2, aluminum alloy doors and windows thickness standard
At present, the cross-sectional geometric dimensions of aluminum alloy profiles for aluminum alloy doors and windows have been serialized, and the latest national standard GB/T8478-2.0mm for aluminum alloy doors and windows has been released, with the release date of March 3, 20265438 1 day and the formal implementation of February 202654381day.
