 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; inner-opening windows are easy to hit children's heads and easily cause rain, sand and dust to invade indoors. Flat-open and top-hanging: By turning the handle to choose whether to flat-open inward or top-hanging inward, this is currently the opening method that the country vigorously promotes. Advantages: good heat preservation and sound insulation performance; when ventilated, fresh air swirls into the room; when it is windy or rainy, windows can also be opened to keep the indoor air fresh; easy to clean the glass surface facing outside. Disadvantages: The technical content is 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, in addition to flat-opening and flat-opening top suspension, each method has its own advantages and disadvantages. Choose according to your needs.
