At present, the opening mode of aluminum alloy windows in our country adopts push-pull type, and there are also flat open type and top hanging type. Each mode has its own advantages and disadvantages. Users should choose according to their own needs. Let's talk about them one by one.
Push pull type: the window along the track to the left and right or up and down. Advantages: it doesn't occupy indoor and outdoor space, and it is easy to operate, especially suitable for balcony. Disadvantages: the maximum opening degree can only reach 1 / 2 of the whole window area; in rainy days, the window can only be closed and cannot be ventilated; it is difficult to clean the glass surface facing outwards; the sealing is poor, and moisture and dust are easy to enter; the sliding rail under the window frame slides back and forth, with large space on the top and the gap between pulleys at the bottom, resulting in large heat loss.
Casement: it is a kind of traditional window type, which can be divided into external casement window and inner casement window. The window sash can be single or double. Advantages: there are rubber sealing strips between the window sash and the window frame, with good sealing performance; the outer side hung window has good waterproof performance, and does not occupy the indoor space when opening; the inner side opening window is easy to be scrubbed frequently to keep the window clean. Disadvantages: the external open window will occupy the outdoor space; the inner open window is easy to hit the children's head, and it is easy to cause rain and dust to invade the interior.
Horizontal opening and overhanging type: turning the handle to select whether to open inward or upward from the top is the opening mode vigorously promoted by the state. Advantages: it has good thermal insulation and sound insulation performance; when ventilation, fresh air whirls into the room; when it is windy and rainy, you can also open the window to keep the indoor air fresh; it is convenient to clean the glass surface facing outside.
