Which should I choose between a sliding window with a broken bridge and a flat window with a broken bridge?
1. Appearance comparison.
From an appearance perspective, the difference between casement windows and sliding windows lies in their compatibility with the overall style of the building. casement windows are more flexible and can create any linear facade effect. For french window, a small part of the whole window is more suitable for more stringent requirements on the overall effect of the building. The real estate that meets the building requirements is spacious, spacious, bright, transparent, coordinated, and smooth in appearance.
The opening position of sliding windows can only slide horizontally and is difficult to match with large fixed glass areas. It is usually suitable for open factories or rural family buildings with clear horizontal and vertical lines.
2. Performance comparison.
In terms of doors and windows (wind pressure, water tightness, air tightness), flat windows are better than sliding doors. The wind pressure performance of doors and windows depends on the resistance moment of the main load-bearing components of the doors and windows. The larger the profile section, the greater the resistance moment, but a proportional relationship cannot be achieved.
The cross-section of the side hung window frame is relatively small, and the pressure bearing components are generally made of composite or vertical materials. These main load-bearing components will be strengthened during the design process, so their wind pressure resistance performance will be better.
The cross-section of sliding window profiles is usually large, which is the reason for improving wind pressure resistance performance. However, with a small amount of in-depth force analysis, it can be determined that the main component is the intermediate fan material, and only the pulleys bear the horizontal direction when going up and down stairs. The wind load and wind pressure resistance performance are not ideal.
The water tightness of doors and windows depends on the sealing effect of the opening. Flat windows are sealed with rubber strips, while sliding windows are sealed with wool strips. The sealing effect of rubber strips is better than that of wool strips.
In terms of airtightness, currently on the market, two-point locks or sky and earth locks are used to lock and seal the opening fans of casement windows, which have better sealing effects. Sliding windows are all locked with hook locks or pins, and the sealing effect is not ideal.
Side hung windows are better than sliding windows in three aspects, so large commercial and residential buildings choose side hung windows.
3. Insulation comparison.
In terms of thermal insulation performance, casement windows on the market are sealed with sealing strips, while sliding windows are sealed at the top. The sealing effect of rubber strips is better than that of the top. Two point locks or sky and earth locks are used to lock and seal the opening of casement windows, which has a better sealing effect. Sliding windows are generally locked with hooks or pins, but the sealing effect is not ideal.
4. Price comparison.
The price difference between casement windows and sliding windows of the same level is relatively small, with casement windows slightly higher than sliding windows. The price of ordinary casement aluminum windows is 200-350 yuan/㎡, mid-range aluminum windows are 450-600 yuan/㎡, high-quality casement windows are generally priced at 800 yuan/㎡ or above, ordinary sliding windows are generally priced at 150-300 yuan/㎡, mid-range aluminum alloy sliding windows are priced at 350-500 yuan/㎡, and high-quality sliding windows are priced at 600 yuan/㎡ or above.
5. Craftsmanship.
In terms of processing and production, sliding windows have a simple structure and no special equipment requirements. Therefore, flat windows processed in small factories are connected by 45 ° thick aluminum angle steel, requiring better angle collision machines. Double headed cutting saws can produce high-quality aluminum alloy flat windows.
The performance of casement windows is superior to sliding windows, and in the future, casement windows will be widely used and become the main development trend.

What are the advantages of choosing insulated aluminum alloy profile windows?
What are the advantages of choosing insulated aluminum alloy profile windows? Compared with the standardized aluminum door and window architecture, insulated aluminum alloy profile windows have many advantages. For example, insulated aluminum alloy profiles will be integrated with reinforced acrylic resin rods for thermal insulation and frost resistance. Insulated aluminum alloy profiles and reinforced acrylic resin rods can generate insulation system software to block outdoor heat, cold, and noise. Ensure warmth in winter and coolness in summer, and provide a very comfortable natural environment for building construction.
