1. Appearance comparison The difference between casement windows and sliding windows in appearance 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 sash only takes up 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, it is especially in line with the architect's pursuit of a large-scale, spacious and bright, transparent effect, and a coordinated and smooth appearance. 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 compartment. Generally, they are more suitable for open factories or rural home buildings with clear horizontal and vertical lines.
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 a small profile section, but their 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 stands to reason 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 bear the horizontal wind load, so its wind pressure resistance performance 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 tops. The sealing effect of rubber strips is generally better than that of tops.
In terms of airtightness, 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. Thermal insulation comparison In terms of thermal insulation performance, the current 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 casement windows, which has better sealing effect. The sliding windows are generally locked by hook locks or latch locks, and the sealing effect is not ideal.
