1. Appearance comparison

In appearance, the difference between casement windows and sliding windows is mainly in the matching with the overall style of the building. Casement windows can be made into any line of facade effect due to the flexibility of their divisions. For large-division French windows, the opening fan only occupies a small part of the whole window, so it is more suitable. For high-end real estate with strict requirements on the overall effect of the building, it is especially in line with the architect's pursuit of a large, spacious, bright, transparent, and well-coordinated building.

Sliding windows can only be horizontally pushed and pulled, so they are difficult to match with the fixed glass of large divisions. They are generally more suitable for open factories or ordinary family buildings with clear horizontal and vertical lines. In terms of usage habits, people are more comfortable. Used to use sliding windows.

2. Performance comparison

In terms of the three performances of doors and windows (wind pressure resistance, water tightness, and air tightness), casement windows are generally better than sliding windows. The wind pressure resistance performance of doors and windows depends on the resistance moment of the main force-bearing members of the doors and windows. The larger the section of the profile, the larger the resistance moment, but it is not completely proportional.

Casement windows generally have small cross-sections, but the main force-bearing members are often made of composite or mid-vertical materials. These main force-bearing members will be strengthened accordingly during the design process, so their wind pressure resistance performance is better. .

The cross section of the sliding window profile is generally larger, and it is reasonable to say that its wind pressure resistance performance should be better, but as long as a little in-depth analysis of the force, the main force member is often the middle fan material, and its upper and lower stiles only rely on pulleys. To withstand the horizontal wind load, its resistance to wind pressure is generally not ideal.

The water tightness of doors and windows depends on the sealing effect of the opening part. Casement windows are generally sealed with rubber strips, while sliding windows are generally sealed with wool strips. The sealing effect of rubber strips is generally better than that of wool strips.

In terms of air-tightness, two-point locks or sky-earth locks are used to lock and seal the opening fan of casement windows on the market at present, and the sealing effect is better. The sliding windows are generally locked by hook locks or latch locks, and the sealing effect is not ideal.

Therefore, casement windows are generally better than sliding windows in three aspects. This is why most high-end commercial and residential buildings choose to use casement windows.

3. Price comparison

There is little difference in price between casement windows and sliding windows of the same grade, and casement windows are slightly higher than sliding windows. The price of ordinary casement aluminum windows is 200-350 yuan/㎡, the price of mid-range windows is 450-600 yuan/㎡, and the price of high-end casement windows is generally above 800 yuan/㎡. Ordinary sliding doors and windows are generally 150-300 yuan/㎡, mid-range aluminum alloy sliding windows are 350-500 yuan/㎡, and high-end sliding doors and windows are above 600 yuan/㎡.

In summary, casement windows and sliding windows are different, each has advantages and disadvantages. Therefore, manufacturers of automotive aluminum alloy sliding windows remind everyone that they should not only look at one aspect when buying, but start from multiple aspects. Choose the most suitable one according to your needs.
