The performance of the casement window is better than that of the sliding window, but the sliding window is better than the casement window in terms of processing and operation. For this reason, casement windows are widely used in urban commercial and residential buildings, office buildings, high-end residences, villas and other mid-to-high-end buildings; while sliding windows are widely used in industrial plants, rural residences and other mid- and low-end buildings. Aluminum alloy doors and windows are classified according to 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 to open inward or outward; sliding doors and windows mainly refer to doors and windows in which the sashes are vertically pushed and pulled left and right 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.
In appearance, the difference between casement windows and sliding windows is mainly in the matching 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, well-coordinated and smooth 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 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 is better. . The cross section of the sliding window profile is generally larger, and it is reasonable to say 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 withstand the horizontal wind load, the anti-wind pressure 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 sky-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.

In terms of thermal insulation performance, casement windows on the market are generally sealed with sealing tape, 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.
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 degrees. The "corner hitting machine" and "double-head cutting saw king" can produce excellent aluminum alloy casement windows.
In summary, the performance of casement windows is better than that of sliding windows, and casement windows are widely used.
