What's the difference between a casement window and a sliding window?

As the saying goes, "eyes are the windows of the soul", then conversely, the windows of a house are actually equivalent to people's eyes! Windows not only play the role of ventilation and exchange with the external environment, but also play the role of decorating houses and creating indoor environment! With the improvement of people's quality of life, there are more and more kinds of windows, such as casement windows, shutters, sliding windows and skylights. Casement windows and sliding windows are more common. Do you know what a casement window is? What's the difference between a casement window and a sliding window? In order to give you a better understanding, today I will tell you what a casement window is, and what is the difference between a casement window and a sliding window!

1. What is a casement window?

The casement window is the most common window, which is divided into two types: inward opening and outward opening. Casement window, the sash is combined with the window frame through hinges, and the sash can be rotated and opened. This kind of window has the advantages of simple structure, the whole window can be opened 100%, large opening area, good ventilation, good air tightness when closed, and excellent sound insulation, heat preservation and heat resistance. In today's increasingly demanding building energy efficiency, casement windows will become the mainstream of the market. The disadvantage of casement window is that the window width is small and the field of vision is not wide. The outer window occupies the space outside the wall and is easy to be damaged when it is windy; The inner window takes up some indoor space, so it is not convenient to use the screen window. It is also inconvenient to use screens and curtains when opening windows. If the quality is not up to standard, it may leak rain.

Later, aluminum alloy plastic steel windows appeared. It is a new form developed on the basis of casement window. There are two ways to open it, which can be opened horizontally or pushed from the top. When the casement window is closed, the upper part of the window is pushed outward, so that the gap of about 10 cm can be opened, that is, a little window can be opened from above, and the opened part is suspended in the air and connected and fixed with the window frame through hinges, so it is called the upper suspension type. Its advantages are ventilation and safety. Because of the hinge, the window can only open the seam of 10 cm, which can't be reached from the outside, so it is especially suitable for use when no one is at home. Recently, this function has not only been limited to casement windows, but also sliding windows can be opened by hanging.

The advantages of sliding window are simple and beautiful, wide window, large glass block, wide field of vision, high daylighting rate, convenient glass cleaning, flexible use, safety and reliability, long service life, opening in one plane, less occupied space and convenient installation of screen window. At present, the sliding window is the most widely used. The disadvantage is that two windows can't be opened at the same time, only half of them can be opened at most, and the ventilation is poor; Sometimes the sealing is slightly poor.

Second, the conventional size of casement window

There are 60 series of casement windows. Fixed windows, inner casement windows, outer casement windows, inner casement windows, sliding windows, special casement windows, circular-arc casement windows of various specifications can be produced according to the atlas issued by the Ministry.

1 and 60 casement windows: window frame: 2400x2400 sash: 750x 1600.

2.60 casement window: window frame: 2 100x2 100 sash: 1000x 1600.

Third, the difference between casement window and sliding window:

1, the appearance is different.

The difference between casement window and sliding window in appearance mainly lies in the collocation with the overall style of the building. Because of its greater flexibility, casement windows can make any vertical effect of lines, while for floor-to-ceiling windows with large partitions, the opening fan only accounts for a small part of the whole window, so it is more suitable for high-end buildings with strict requirements on the overall effect of the building, especially buildings with large partitions, spaciousness and brightness, good permeability and smooth appearance. Sliding windows can only be pushed and pulled horizontally, which is difficult to match with large divided fixed glass. They are generally suitable for open workshops or rural family buildings with clear horizontal and vertical lines.

2, the price is different

The price difference between casement window and sliding window of the same grade is not big, and casement window is slightly higher than sliding window. The price of ordinary plane aluminum alloy windows is 200 ~ 350 yuan/m2, and the price of middle and high-grade windows is above 460 yuan/m2. Push doors and windows generally 150 ~ 200 yuan /m2.

3, warm effect

In terms of thermal insulation performance, casement windows in the market are generally sealed with sealing strips, while sliding windows are generally sealed with top strips, and the sealing effect of sealing strips is generally better than that of top strips. The opening fan of casement window is usually sealed by two-point lock or heaven-earth lock, and the sealing effect is good. However, the sliding window is usually locked by hook lock or touch lock, and its sealing effect is not ideal.

Step 4 perform

From the three characteristics of doors and windows (wind pressure resistance, water tightness and air tightness), casement windows are generally superior to sliding windows. The wind pressure resistance of doors and windows depends on the resistance moment of the main stress bar of doors and windows. Usually, the larger the cross section, the greater the resistance moment, but it is not completely proportional. Generally, the profile of casement window is small, but its main stress components are assembled or vertical, and these main stress components will be strengthened in the design process, so its wind pressure resistance is good. Generally speaking, the section of sliding window profile is relatively large, so its wind pressure resistance should be better. However, as long as we make a little in-depth stress analysis, we know that its main stress bar is often made of middle fan material, and its upper and lower vertical frames are only supported by pulleys in the horizontal direction, so its wind pressure resistance is generally not ideal. The watertightness of doors and windows depends on the sealing effect of the opening part, and casement windows are generally sealed with adhesive tape. In terms of air tightness, two-point lock or heaven-earth lock is often used in the market to lock the opening fan of casement window. Therefore, casement windows are generally superior to sliding windows in three aspects. This is why most high-grade commercial and residential buildings choose to use casement windows.

5. Production process

In processing and manufacturing, sliding windows are generally simple in structure and have no special requirements for equipment, and are processed and manufactured with small chainsaws in small workshops; Because the casement window is connected by 45-degree thick aluminum alloy corner pieces, it needs a good "punching machine" and "double-head cutting saw king" to make an excellent aluminum alloy casement window.
