[China Glass Net] (1) According to the different opening methods, it can be divided into fixed window, casement window, horizontal rotation window, vertical rotation window and sliding window.
The fixed window cannot be opened. Generally, there is no window sash, and the glass can only be embedded on the window frame. Sometimes it has the same facade effect as other windows, but also a window sash, but the sash is fixed on the window frame.
The casement window is hinged on one side of the sash and connected to the window frame. Like the swing door, it has a single fan and a double fan. It can be opened inside or outside. The casement window has a simple structure, is convenient to manufacture and install, has good wind and ventilation effects, and is widely used.
The horizontal rotation window has the upper suspension window, the middle suspension window and the lower suspension window according to the position of the rotation axis. When the upper hanging window and the middle hanging window are used for the outer window, the ventilation and rainproof effects are better, but they are also often used as the air window on the door and window; the lower hanging window is used less.
The rotating shaft of the vertical rotating window is located in the middle of the upper and lower heads, and the sash can be rotated vertically. This kind of window has good ventilation and rainproof effect, and is easy to scrub the sash, but the structure is complicated and the rainwater leakage performance is poor, so it is not used much.
The sliding window is divided into two types: up and down sliding and left and right pushing and pulling. The opening of the sliding window does not take up space, but the ventilation area is small (only half of the casement window).
(2) According to the materials used, the windows can be divided into aluminum alloy doors and windows, plastic steel windows, wooden windows, glass steel doors and windows of various composite doors and windows.
At present, the approximate usage ratios of aluminum, plastic and wooden doors and windows on the market are 60%, 30% and 2% respectively.
According to many companies and industry organizations, aluminum windows in the south of the Yangtze River and East China account for almost 80% or more of the market share, while plastic windows are almost extinct. In the future, aluminum alloy doors and windows will still be the dominant door and window. Although the market share in the building door and window market is slightly reduced, it can still remain above 55%.
The energy-saving effect of plastic windows can not be ignored, and the cost performance has been widely recognized.
All kinds of solid wood and wooden composite doors and windows are gradually sought after by consumers due to their beautiful appearance and energy-saving performance. And the lower the K-value requirement of the door and window, the higher the cost performance of the wooden window. Aluminum-clad wood doors and windows are the best choice for high-end projects in important cities in Beijing and surrounding areas. Even many affordable housing projects have begun to use aluminum-wood composite doors and windows.
With the rise of passive houses, various composite doors and windows, such as aluminum-wood composite, FRP-wood composite doors and windows began to develop toward the passive window.
(3) According to the different mosaic materials, the window can be divided into glass windows, screen windows, louver windows, thermal insulation windows and windproof sand windows.
The glass window can meet the requirements of the lighting function; the screen window can prevent the mosquitoes from entering the room while ensuring ventilation; the louver is generally used for rooms that need only ventilation and no need for lighting, and the louver window is divided into fixed louver and movable louver. Two kinds of activities, the louver can be added outside the glass window, which plays the role of shading and ventilation.
(4) According to the different positions of the windows on the building, the windows can be divided into two types: side windows and skylights, which are arranged on the inner and outer walls, called “side windowsâ€; windows placed on the roof are called “ Skylight." The windows described above are all side windows. When the side window can not meet the requirements of lighting and ventilation, skylights can be installed to increase lighting and enhance ventilation. Depending on the construction method, the skylight can be divided into a convex sunroof, a sunroof sunroof, a flat sunroof and a zigzag sunroof.
