The windows are mainly divided into casement window, sliding window, upper hanging window, lower hanging window, inner horizontal opening and lower hanging window, etc. These are common window opening methods. Each has its own advantages and disadvantages. Which one is better? The following section lists the advantages and disadvantages of various window opening methods
1、 Casement window
It refers to doors and windows with hinges or hinges installed on the side of doors and windows, which are opened inward or outward. Aluminum alloy casement window belongs to high-grade doors and windows, the main series are: 58 series, 60 series, 65 series. The sash of casement window can be opened to indoor or outdoor, which is called inner casement window and outer casement window respectively. Casement windows generally have double seal, three seal, four seal structure, so the sealing performance is very good, can install double-layer, three-layer insulating glass.
Advantages: flexible opening mode, large opening area, good ventilation performance and strong intensity. Large fixed small opening form can be adopted in the window opening design, which has good lighting performance and beautiful atmosphere. The sealing performance, sound insulation performance, thermal insulation performance and impermeability of the casement window are very good. The interior casement window is easy to clean and change, and the outer open window does not occupy extra space.
Disadvantages: the interior window takes up the indoor space when opening the window, which is easy to knock and hurt people. If the curtain is used, it is more inconvenient. Once the quality of the window is not up to standard, it may seep into the rain; the installation and use of the screen window is not convenient for the outer side window, and there are certain safety risks in the use of the window sash. According to the local standard dbj01-79-2004, the middle and high-rise buildings (usually more than 10 floors in actual construction) are strict It is forbidden to use the external casement window, and the opening of the external window needs to occupy a space outside the wall, so it is easy to be damaged or even fall to hurt people in case of strong wind.
2、 Sliding window
Through the external force acting on the window sash to drive the pulley rolling to realize the opening and closing of the window sash. It is a single, double or multi leaf door and window that is pushed and pulled to the left and right. Sliding window is an economic and practical door and window. Aluminum alloy sliding window series mainly include 85 series, 88 Series and 90 series, which are mostly used in balcony, kitchen, toilet, staircase and other indoor environment.
Advantages: the sliding window is simple and beautiful, with large window width, wide field of vision, high lighting rate, easy to use, safe and reliable, long service life, relatively free selection of window position and vent, and no occupation of indoor space when opening. Open in one plane, it is convenient to install and use screen window and curtain.
Disadvantages: compared with casement window, the sealing of sliding window is poor. Two windows can not be opened at the same time, and can only be opened half at most. The ventilation is relatively poor.
3、 Inner side hung window
It refers to a window that can be opened horizontally or suspended downward. It is commonly known as an inward tilting window or an inward inverted window. This is a kind of door and window opening method that is more popular with the owners at present.
Advantages: it has the advantages of both side hung window and bottom hung window, which can be opened flexibly. When a large amount of air exchange is not needed, the open fan takes up less space, and the wind enters from the side and upper part of the window sash to avoid direct blowing to the human body and achieve the effect of ventilation. When a large amount of indoor air needs to be changed, it can be easily changed into a casement window.
Disadvantages: more hardware accessories are used for the inner horizontal opening lower suspended window, so the price of aluminum alloy doors and windows with this opening mode is relatively higher.
