Abstract: A hung window is a window that opens along the horizontal axis. According to the position of the hinge and the rotating shaft, it can be divided into a top-hung window and a bottom-hung window. As the name suggests, it is a window that opens upwards or downwards. Top-hung windows have the characteristics of good ventilation, safety and anti-theft, easy to clean, strong practicability, and good sealing and heat preservation performance. They are different from bottom-hung windows in three aspects: opening method, function and application occasions. Top-hung windows and bottom-hung windows have their own advantages and disadvantages. There is no such thing as good or bad. Owners can choose according to their own needs and preferences when decorating. Let's learn about top-hung windows and bottom-hung windows!

1. What is a top hung window

Top-hung windows, commonly known as outward-turning windows, refer to top-hung windows whose hinges (hinges) are installed on the upper side of the window and open to the outside. Top-hung windows that open outwards are a type of hung windows, which belong to the casement window system like other hung windows.

2. What is a bottom-hung window

Bottom-hung windows are generally installed on the lower side of the window and are windows that open toward the interior. The bottom-hung window is usually said to be a bottom-hung window that opens inward.

3. What are the characteristics of top-hung windows?

1. Good ventilation

Because the inverted position is another way to open the casement window, the room can be naturally circulated with the natural air, the indoor air is fresh, and the possibility of rainwater entering the room is eliminated. Clean air undoubtedly creates a comfortable living environment for people.

2. Security and anti-theft

The linkage hardware arranged around the window sash and the various functions of the handle can be operated indoors. When the window sash is closed, the surroundings of the window sash are fixed on the window frame, so the safety and anti-theft performance is excellent.

3. Easy to clean windows

The operation is simple, and the outside of the window sash can be turned indoors. It is convenient and safe to clean the outer surface of the window.

4. Strong practicability

It avoids occupying indoor space when the inward opening window is opened, and it is inconvenient to hang curtains and install lifting clothes rails.

5. Good sealing and heat preservation performance

Multi-point locking around the window sash ensures the sealing and heat preservation effect of doors and windows.

Fourth, the difference between top-hung windows and bottom-hung windows

1. The opening method is different

The top-hung windows are pushed open from the inside out, and the bottom-hung windows are pulled inwards and upwards or pushed outwards and upwards.

2. Different functions

Because the top-hung windows are opened upwards and outwards, if it rains and the rain is not strong, it can form a certain rainproof effect. The top-hung windows that open outward can also play a role in exhausting smoke.

Bottom-hung windows can play a certain role in heat preservation and sound insulation; when opened inward, the indoor ventilation is good, and the wind will change the direction of the wind when it blows to the window, so the wind will not directly blow to the human body, which can improve the indoor air. The role of quality.

3. Different application occasions

Top-hung windows are suitable for high-rise buildings and are often used in public places such as toilets or glass curtain walls.

Bottom-hung windows are mostly used in glass curtain walls, and there are various opening devices for bottom-hung windows, mainly including push rod type, chain type, rack type, etc. When applied to glass curtain walls, the window opening devices are mostly electric.

Fifth, choose the top-hung window or the bottom-hung window

Top-hung windows generally open outwards, because the shaft is on the top, and you can open the window for ventilation at ordinary times. If it rains or snows, you don’t have to worry about water leaking into the room. Good water blocking effect. In addition, because its switch direction is to push up and down, this avoids the accident of bumping yourself because of opening and closing windows and doors. Of course, it also has its own defects, such as not very beautiful, and it is not very convenient to clean the glass, etc.

Bottom-hung windows generally have more inward-opening designs. As long as you are at home, you can easily clean the windows, saving time and effort. In addition, because there are no obstacles from windows, the ventilation effect is also very good. But this has also become its biggest disadvantage. Because there are no windows to cover, the waterproof effect is poor in rainy and snowy weather, and it is easy to stain the window sill and the interior, and because it is indoors, it also takes up more space.

Generally speaking, both have certain advantages and disadvantages. When decorating, you can decide which window to install according to your own needs and preferences.
