When purchasing aluminum alloy doors and windows, due to the various opening methods of aluminum alloy windows, owners often do not know what opening method to choose. The most popular ones in the market are broken bridge sliding windows and broken bridge casement windows. Broken bridge sliding windows and broken bridge casement windows have their own advantages. As a leader in the field of aluminum doors and windows, Jinyang Aluminum will lead you to discuss their respective characteristics from the appearance, performance, and functional use of doors and windows.
1. Appearance differences
The main difference between a broken bridge casement window and a broken bridge sliding window lies in the style of the building object. Due to its flexible division, the bridge cutoff casement window can produce any line of facade effect. For the large division french window, the opening 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 in line with the architect's pursuit of large area, spacious and bright, transparent effect and harmonious appearance. Broken bridge sliding windows can only be horizontally pushed and pulled, making it difficult to match with fixed glass with larger compartments. Generally speaking, it is more suitable for factories or rural household buildings with clear horizontal and vertical lines.
2. Comparison of wind pressure resistance
The wind pressure resistance performance of doors and windows depends on the resistance torque of the main load-bearing components of the doors and windows. The larger the cross-section of the profile, the greater the resistance torque, but it is not entirely proportional. The cross-section of the broken bridge flat window profile is generally small, but the main load-bearing steel bars are generally made of medium and vertical materials. These main load-bearing bars will be correspondingly strengthened during the design process, thereby improving their wind resistance performance.
The cross-section of the broken bridge sliding window profile is generally large, and its wind resistance performance should be good. But with a slightly deeper stress analysis, it can be known that its main stress reinforcement is often the middle fan material, and its upper and lower keels only rely on pulleys to withstand horizontal wind loads, so the wind pressure performance is generally not ideal.

3. Comparison of water tightness
The water tightness of doors and windows depends on the sealing effect of the opening part. Broken bridge casement windows are generally sealed with rubber strips, while broken bridge sliding windows are generally sealed with wool strips. The sealing effect of rubber strips is generally better than that of wool strips.
4. Air tightness comparison
In terms of airtightness, currently, the opening part of bridge cut flat windows on the market generally uses two-point locks or earth locks, which have a good sealing effect. However, broken bridge sliding windows usually use hooks or latch locks, and their sealing effect is not ideal. Therefore, the three major performance of the broken bridge sliding window is generally better than that of the broken bridge sliding window. That's why most high-end commercial and residential buildings choose to use broken bridge casement windows.
5. Process comparison
In terms of processing and manufacturing, the broken bridge sliding window generally has a simple structure and no special requirements for equipment, making it convenient for small workshop style or on-site processing and manufacturing; Due to the fact that the window sashes of the broken bridge casement windows are generally connected by aluminum codes, a corner collision machine is needed to produce high-performance broken bridge casement windows.
6. Functional comparison
In terms of functionality, the bridge breaking sliding window is favored by a large number of users due to its flexible opening and easy operation; In contrast, broken bridge casement windows are generally connected by hinges and opened by handles, making them less flexible in operation than sliding windows.
The above are the differences between bridge broken sliding windows and bridge broken casement windows. Users can choose the appropriate way to open bridge broken doors and windows according to their actual situation. Jinyang Aluminum hopes that the above sharing can be more helpful to everyone, and welcomes every user to inquire and learn more.
