Are there any differences between casement windows and sliding windows?
The following briefly describes the difference between flat windows and sliding windows.
1. Different appearance
The difference in appearance between casement windows and sliding windows is mainly in the matching with the overall style of the building. The casement window can be made into any line of facade effect because of the flexibility of its division, and for the floor-to-ceiling window with large division, the casement window only occupies a small part of the whole window, so it is more suitable for High-end real estate with stricter requirements on the overall effect of the building, especially in line with the architect's pursuit of large-scale, spacious and bright, transparent effect, and harmonious appearance of the building. Sliding windows can only be horizontally pushed and pulled because they can only be opened horizontally, so they are difficult to match with the fixed glass of the large partitions. They are generally more suitable for open factories or rural home buildings with clear horizontal and vertical lines.
2. The price is different
The price of the same grade is not much different, and the casement window is slightly higher than the sliding window. The price of ordinary casement aluminum windows is 200-350 yuan/square meter, and the price of mid-to-high-end windows is above 460 yuan/square meter. Push doors and windows are generally 150 to 200 yuan/square meter.
3. Warm-keeping effect
In terms of thermal insulation performance, casement windows on the market generally use sealing tapes for sealing, while sliding windows generally use tops for sealing. The sealing effect of rubber strips is generally better than tops sealing. Two-point locks or sky-earth locks are used to lock and seal the opening fan of the casement window, 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.
4. performance
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 resistance performance of doors and windows depends on the resistance moment of the main force-bearing members of the doors and windows. Often the larger the section of the profile, the larger the resistance moment, but it is not completely proportional. The cross section of the general profile of casement windows is small, but the main force-bearing members are usually assembled or mid-vertical. These main force-bearing members will be strengthened accordingly during the design process, so their wind pressure resistance performance is better. it is good. The cross section of the sliding window profile is generally larger, and it stands to reason that its wind pressure resistance performance should be better. However, 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 are used to withstand horizontal wind loads, so wind pressure resistance is generally not ideal. The water tightness of doors and windows depends on the sealing effect of the opening part, and casement windows are generally sealed with rubber strips. It uses two-point lock or heaven and earth lock to lock and seal more parts of its opening fan. 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.
5. Production process
In terms of processing and production, the sliding window has a simple structure and no special requirements for equipment. Therefore, a small workshop with a small electric saw is used for processing and production; and the casement window is connected by thick aluminum alloy angle pieces at 45 degrees, so better Only the "corner hitting machine" and the "double-head cutting saw king" can produce excellent aluminum alloy casement windows.
