Sliding window: divided into left and right, up and down sliding. Sliding windows have the advantages of not occupying indoor space, beautiful appearance, economical price, and good airtightness. It adopts high-grade slide rails, which can be opened flexibly with a light push. With large pieces of glass, it not only increases indoor lighting, but also improves the overall appearance of the building. The window sash has a good stress state and is not easy to be damaged, but the ventilation area is limited. So, today the editor will briefly introduce the characteristics of sliding windows and casement windows.
1. Appearance comparison
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 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.
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.
3. Insulation comparison
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.
4. Price comparison
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. The price of ordinary casement aluminum windows is 200-350 yuan/㎡, the price of mid-range windows is 450-600 yuan/㎡, and the price of high-end casement windows is generally above 800 yuan/㎡. Ordinary sliding doors and windows are generally 150-300 yuan/㎡, mid-range aluminum alloy sliding windows are 350-500 yuan/㎡, and high-end sliding doors and windows are above 600 yuan/㎡.
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 the "double-head cutting saw king" can produce excellent aluminum alloy casement windows.
