Advantages:
1, good ventilation effect.
Because the window sash can be opened to the maximum extent, the indoor and outdoor air can be fully circulated, so the room with casement windows is easier to breathe and can maintain a fresh and comfortable indoor environment.
2. Safety and theft prevention
When the casement window is closed, it is fixed around, and the linkage hardware around the sash and various functions of hand-held operation are fixed on the window frame when it is closed, so it has high safety performance and can play the role of anti-theft.
3, flexible and practical
The casement of the casement window is flexible to move and easy to operate, which can make the outside of the casement turn indoors and avoid occupying indoor space when the inner window is opened.
4, sealing and heat preservation
The casement window has good sealing and thermal insulation performance, and the multi-point locking around the sash ensures the sealing and thermal insulation effect of the doors and windows.
Disadvantages:
1. If you choose the casement window that opens inward, it will occupy indoor space, which is not suitable for small-sized apartment, and it is not recommended to use small-sized apartment. The overall window width of casement window is small, and the field of view is not wide.
2. If you choose the open type, it is easy to be damaged when there is a strong wind, for example, it is not fixed properly, the glass is damaged or the window sash falls directly, which is easy to cause accidents and rust and break after a long time.
3. Use screens, curtains, etc. For example, I want to open the window for ventilation in summer night, and the curtains are not tightly drawn. In addition, the security is not very good. Children may bump their heads while playing, and we may bump our heads when cleaning ourselves and bending over.
