Compared with many residential owners who are preparing for decoration, the choice of windows is a very important issue. Some people think that the function of windows is just to keep out the wind and rain, so there is no need to spend too much time and energy on choosing them. However, others believe that the choice of doors and windows is very important because they will be used for many years. If the selection is inappropriate, it may bring some unexpected troubles. For example, the selection of inappropriate windows may lead to inconvenient opening methods or accidents such as windows falling from high-rise buildings, and such news can often be seen in newspapers. Therefore, we should be highly vigilant, especially when choosing and installing windows.

At present, there are still many homeowners who are not familiar with broken bridge aluminum doors and windows. This article will introduce various opening methods of broken bridge aluminum doors and windows, including fixed type, casement type, outward bottom-hung type, inward top-hung type, outward bottom-hung type, and sliding type.

Fixed windows are suitable for places that need to be fully enclosed. When the window sashes are not opened, the room is airtight, which can better insulate heat, but it may make the room stuffy.

Casement windows are divided into two types: inward opening and outward opening. Inward opening casement windows open inward into the room, which can open the window to the maximum extent to obtain a good ventilation effect. At the same time, they have good sealing, sound insulation, heat preservation and waterproof performance. In order to ensure that the opening position of the window is tightly sealed, sealing rubber strips are installed around the window to ensure the sealing performance of the window. Inward opening casement windows are very convenient to clean, but they will occupy some indoor space when opened.

In contrast, outward opening casement windows open outward, not occupying indoor space. However, its disadvantage is that the opening range is small and the view is not wide enough. In addition, it is easily damaged in windy weather. According to national regulations, outward opening casement windows cannot be used on floors above the 6th floor.

In general, casement windows are a relatively practical type of windows, with good sound insulation, heat preservation, waterproof performance and good ventilation effect. However, when choosing between inward opening and outward opening, it is necessary to consider the actual situation comprehensively.

Inward top-hung windows: This is a new form developed on the basis of casement windows. It has two opening methods, either casement opening or opening upward. When the window is closed in the casement mode, a gap of about ten centimeters can be pulled out at the top, and the opened part is suspended in the air and fixed by connecting with the window frame through an oblique pull rod. Therefore, it is called an inward top-hung window. Its advantage is that it can achieve both ventilation and save indoor space, and it is very safe. When the window is opened in the top-hung mode, it is impossible for people outside to reach in, which is especially suitable for use when there is no one at home. If it rains slightly when you go out, opening it in the top-hung mode will prevent rainwater from entering the room.

Bottom-hung windows: Bottom-hung windows are designed with the window handle located below the middle of the window. They can be pushed outward to create a space of about ten-odd centimeters, which is conducive to ventilation and can save indoor space. However, bottom-hung windows are usually suitable for users on lower floors. Since they open outward, it is not recommended to use them on high-rise buildings, and this opening method is relatively rare.

The term "outward bottom-hung" means that the window has two opening methods, either opening horizontally outward or hanging downward outward. Its ventilation effect is the same as that of the "inward top-hung" type, and it can also effectively prevent rainwater from entering the room. However, it is not so convenient to clean this kind of window, and its safety is not as high as that of the "inward opening" type.

Sliding windows have a simple and beautiful opening method, and the opening range is relatively large. They only open within one plane, occupy less space, are easy to operate, and are also convenient for installing window screens. However, the only disadvantage is that the two sashes cannot be fully opened at the same time, and at most only half of them can be opened. In windy and rainy weather, the windows can only be closed, and ventilation cannot be carried out. In addition, it is relatively difficult to clean the outer glass of the window. In terms of the sealing and heat preservation performance of the windows, the sealing effect of sliding windows is not as good as that of casement windows, which makes it easier for humid air and dust to enter the room. The lower sliding track of the window frame needs to slide frequently, and there is a large gap above, and the gap between the pulleys will also lead to greater energy loss.

For different housing types and structural designs, the selected window opening methods will vary. However, currently most users adopt the inward top-hung opening method, which is convenient, simple and safe. However, some window positions may be blocked. For example, for the window position in the kitchen, there may be a faucet and a sink, which will prevent the window from opening inward. In this case, only the outward opening, outward bottom-hung or sliding operation methods can be adopted. However, according to national regulations, windows on floors above the sixth floor are not allowed to open outward, so it is necessary to communicate with the on-site measurement master.
