Push-pull type: The window is pushed and pulled left and right or up and down along the track. Advantages: It does not occupy indoor or outdoor space, and is easy to operate, especially suitable for balconies. Disadvantages: The maximum opening degree can only reach 1/2 of the entire window area; in wind and rain, the window can only be closed without ventilation; it is difficult to clean the outward-facing glass surface; the airtightness is poor, and moisture and dust can easily enter the window; The slide rail of the frame slides back and forth, there is a large space on the top, and a gap between the pulleys below, causing a large heat loss. Casement: It is a traditional window type, divided into two types: outer casement window and inner casement window. The sash can be single or double. Advantages: There are rubber sealing strips between the window sash and the window frame, which has good sealing performance; the outer casement window has good waterproof performance and does not occupy indoor space when it is opened; the inner casement window is convenient for frequent cleaning to keep the window clean. Disadvantages: outward opening windows will take up outdoor space; inward opening windows are easy to hit children's heads and can easily cause rain and sand to invade the room. Flat-open and top-hanging: By turning the handle to choose whether to flat-open inward or top-hanging inward, this is the opening method that the country vigorously promotes. Advantages: It has good heat insulation and sound insulation performance; when ventilated, fresh air swirls into the room; when it is windy or rainy, the windows can also be opened to keep the indoor air fresh; it is easy to clean the outward facing glass surface. Disadvantages: The technical content is relatively high, the hardware is mostly imported from abroad, and the price is relatively high. The opening method is adapted to the needs. At present, most of my country’s plastic steel windows follow the opening method of aluminum alloy windows, using push-pull, and there are also flat-open and flat-open top suspensions. Each method has its own advantages and disadvantages. Choose according to your needs.
