The differences between sliding window and casement window

Time : 2023-03-17 Hits : 7

The casement window is superior to the sliding window in performance, but the sliding window is superior to the casement window in processing, manufacturing and operation. For this reason, casement windows are widely used in urban commercial and residential buildings, office buildings, high-end residential buildings, villas and other high-end buildings; The sliding window is widely used in industrial buildings, rural houses and other low-grade buildings. Aluminum alloy doors and windows are classified according to their opening methods. The more popular and practical window types in the market are sliding windows and casement windows. Casement window refers to the door and window with hinges (hinges) installed on the side of the door and window to open inward or outward; Sliding doors and windows mainly refer to the doors and windows whose sashes are pushed vertically along the horizontal direction. The push-pull and horizontal opening are compared when the same glass and accessories are used. Each has its own advantages. Next, we will discuss their respective characteristics in detail in terms of the appearance, performance, price and use function of doors and windows.

Do you know the differences between sliding window and casement window?

Specific appearance

In appearance, the difference between casement window and sliding window is mainly in the collocation with the overall style of the building. Because of its flexibility of division, casement window can make any line elevation effect, and for the large division french window, 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 for the overall effect of the building, especially in line with the large division, spacious, bright A building with good transparency and harmonious and smooth appearance. The sliding window can only be opened horizontally, so it is difficult to match with the fixed glass with large divisions. Generally, it is more suitable for open factories or rural family buildings with clear horizontal and vertical lines.

Specific performance

In terms of the three properties of doors and windows (wind pressure resistance, water tightness and air tightness), casement windows are generally better than sliding windows. The anti-wind pressure performance of doors and windows depends on the resistance moment of the main stressed members of the doors and windows. The larger the section of the profile, the greater the resistance moment, but it is not completely proportional. The section of casement window is generally small, but its main load-bearing members are usually made of frame material or medium vertical material. These main load-bearing members will be correspondingly strengthened during the design process, so their wind pressure resistance performance is good. The sectional area of sliding window profile is generally large, and its wind pressure resistance performance should be relatively good, but as long as the stress analysis is a little deeper, it can be seen that its main stress bar is often made of medium fan material, and its upper and lower mullions only rely on the pulley to bear the horizontal wind load, so the wind pressure resistance performance is generally not ideal. The water tightness of doors and windows depends on the sealing effect of the opening part, and the casement windows are generally sealed with rubber strips. In terms of air-tightness, there are many openings of casement windows in the market, which use two-point locks or heaven and earth locks for locking and sealing. Therefore, casement windows are generally better than sliding windows in terms of three sexual functions. This is why most high-end commercial and residential buildings choose to use casement windows.

Than keeping warm

In terms of thermal insulation performance, the flat casement windows in the market are generally sealed with sealant strips, while the sliding windows are generally sealed with wool strips. The sealing effect of the rubber strips is generally better than that of wool strips. If there are many parts of the open leaf of the casement window, the two-point lock or the heaven and earth lock are used for locking and sealing, and the sealing effect is better. However, the sliding window is generally locked by hook lock or latch, and its sealing effect is not ideal.

Specific process

In terms of processing and manufacturing, the sliding window is generally simple in structure and has no special requirements for equipment, so it is processed and manufactured in a small workshop of a small electric saw; Because the casement window is connected by 45 degrees thick aluminum alloy corner pieces, it needs a better "corner striking machine" and "double-head cutting saw king" to make excellent aluminum alloy casement window.
