Here is the Aluminium Profiles Window Factory to answer you about the type of windows that are more suitable for home improvement, and I hope it will be helpful to everyone.
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 sash only takes up 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 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.
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 Aluminium Sliding Window profiles 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-bearing member is often the middle fan material, and its upper and lower stiles only rely on The pulley bears 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 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.
In terms of thermal insulation performance, current casement windows on the market are generally sealed with sealing tapes, while sliding windows are generally sealed with tops. The sealing effect of rubber strips is generally better than that of tops. Two-point locks or sky-earth locks are used to lock and seal the opening fan of the casement window, which has a better sealing effect. The sliding windows are generally locked by hook locks or latch locks, and the sealing effect is not ideal.
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.
In terms of processing and production, sliding windows are generally simple in structure and have no special requirements for equipment, so they are processed in a small workshop with small electric saws; casement windows are better because they are connected by thick aluminum alloy angles at 45°. Only the "corner hitting machine" and "double-head cutting saw king" can produce excellent aluminum alloy casement windows.
In summary, the performance of Casement Window is better than that of sliding windows. It is believed that in the future, casement windows will be widely used and become the main development trend.
