A window is an opening in a wall, door, roof or vehicle that allows the passage of light, sound, and/or air.

Casement windows are better than sliding windows in performance, but sliding windows are better than casement windows in terms of processing and operation. Because of this reason, casement windows are widely used in urban commercial and residential buildings, office buildings, high-end residential buildings, villas and other medium and high-end buildings; while sliding windows are widely used in industrial plants, rural residences and other medium and low-end buildings. Aluminum alloy doors and windows are classified in terms of their opening methods. The more popular and practical window types on the market are sliding windows and casement windows. Casement windows refer to doors and windows with hinges (hinge) installed on the sides of doors and windows that open inward or outward; sliding doors and windows mainly refer to doors and windows in which the sashes are vertically pushed and pulled in the horizontal direction. Push-pull and flat-opening are compared with the same glass and accessories. Each has its own strengths, the following is a detailed discussion of their respective characteristics in terms of appearance, performance, price and use functions of doors and windows.
1. Than appearance
In appearance, the difference between casement windows and sliding windows is mainly in the combination with the overall style of the building. Because of the flexibility of the division of the casement window, it can be made into any line of facade effect, and it is very important for Oita. For floor-to-ceiling 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, especially in line with the large-scale, spacious, bright, and transparent effect pursued by architects. Good, harmonious and smooth building. Sliding windows can only be pulled horizontally because they can only be opened horizontally, so they are difficult to match with the fixed glass of large divisions. They are generally more suitable for open factories or rural home buildings with clear horizontal and vertical lines.
2. Specific 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. Casement windows generally have small cross-sections, but their main force-bearing members are usually made of assembling materials or vertical materials. These main force-bearing members will be strengthened accordingly during the design process, so their wind pressure resistance performance . 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 only a little in-depth force analysis will show that 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, the wind pressure resistance performance 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. In terms of air tightness, two-point locks or heaven and earth locks are used to lock and seal the opening fans of casement windows on the market. 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. Keep warmer than
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. Than the craft
In terms of processing and manufacturing, 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 degrees. "Corner hitting machine" "Double-head cutting saw king" can produce excellent aluminum alloy casement windows
