Waterproof design of door and window structure from thermally broken aluminum windows aluminum window factory

⑴The principle of equal pressure is actively adopted in the structural design of aluminum alloy doors and thermally broken aluminum windows aluminum window factory, which is the most effective way to improve the waterproof and sealing performance of doors and windows.

⑵The overlap between the movable fan and the thermally broken aluminum windows aluminum window factory frame should not be too small, and the overlap between the movable fan and the window frame of the casement window should not be less than 6mm.

⑶ High-rise buildings, cold areas and areas with higher energy-saving requirements, try to use side-hung doors and windows structure, and use less or no sliding door and window structure. Because there is a large gap between the sliding door and window movable sash and the upper and lower rails, and the two adjacent sashes are not on the same plane, there is no sealing pressure between the two sashes, and only the tops are used for overlapping and overlapping. There are gaps between the tops, and the sealing effect is very weak, so the waterproof and sealing performance of sliding doors and windows is very poor. However, there are 2 to 3 sealing rubber strips between the window sash and the window frame of the casement door and window. The sealing rubber strip is tightly pressed after the window sash is closed and locked, and the middle cavity can easily form an isobaric cavity, so it can Design doors and windows with excellent sealing performance.
⑷The aluminum alloy glass pressure line of the door and window installation glass should be designed in the indoor direction to avoid water seepage in the fine gap between the glass pressure line and the window frame.
⑸The sliding door and thermally broken aluminum windows aluminum window factory of the sliding type should be designed with a high enough water baffle on the indoor side, otherwise, when the outdoor rain has a certain pressure, the rainwater will cross the baffle and flow into the room.
⑹The upper part of the movable fan of doors and thermally broken aluminum windows aluminum window factory should be provided with a drape, and the lower part should be provided with drainage holes.
⑺ The combined doors and windows minimize the exposed joints, because the small gaps cannot be sealed with sealant and leak. When the exposed joints cannot be avoided due to structural reasons, the two contact surfaces of the profiles at the joints form 90°, which is convenient for sealing with sealant.

1. The sealing problem of aluminum alloy doors and windows: the biggest problem of the sliding system is the poor sealing
In Beijing, the mainstream of doors and windows is still sliding windows, but due to the simplicity and objective restrictions of the doors, most of them are sliding doors. However, simple sliding doors have some problems. Imagine the heat convection inside and outside a door. ?
In many projects, it will be found that due to insufficient heat insulation materials for casement windows, some good heat insulation strips and throttling phenomenon, but sliding windows do not, so the use of simple sliding doors actually affects the entire building energy saving system Said that it has formed one of the biggest weak links. When talking about the lock system of doors and windows, what we often see is the single-point lock system. Generally speaking, it must have a certain degree of wind resistance. In the sliding door system, all the lock walls of the entire door are only a limit system and cannot make the door Free movement, simple push-pull systems are all mobile, and you can’t move if you touch the window frame. The entire sinking window frame does not form a stressful structure. In a sense, this lock point is very fragile to prevent theft. Speaking of the anti-theft function, the applicability has not improved for the whole function.

In Europe, sliding doors are also used a lot, the most common is the inward sliding door system. After a Buick commercial vehicle, it is an inward sliding door system. For a simple sliding door application, it may be calculated that due to the use of a heat-insulating substrate, it can be insulated, but it is not good for the essence of use.

China's door and thermally broken aluminum windows aluminum window factory inspection standards require that all opening seams be completely ignored for air tightness, and the air tightness of the entire frame system or the complete door and window system is not tested. This is essentially different from the European standard. The European testing system sends the complete window directly from the opening to the laboratory for experimentation. If the window leaks, the insulation reaches 40%, and the test cannot be passed. When using China to pass the inspection of doors and thermally broken aluminum windows aluminum window factory, the winter will still feel cold.
