Compared with the traditional sliding window type, the opening method of the aluminum profile casement window is more flexible.

The casement window can be fully opened or half opened, which is convenient for adjusting the indoor ventilation rate.

In addition, the door and window frame of the casement window is narrow and the window eye is large, which not only allows more natural light to shine into the room, but also increases the openness of the indoor view and the sense of space.
