Because the inverted position is another way of opening the casement window, it enables the room to circulate naturally with the natural air, and the indoor air is fresh, and at the same time, it excludes the possibility of rainwater entering the room. Fresh air undoubtedly creates a comfortable living environment for people.
2. Safety. The linkage hardware and handles arranged around the window sashes are operated in the room with various functions, and the sashes are fixed on the window frame all around when they are closed, so the security and anti-theft performance is excellent.

4. Practicality. Avoid taking up indoor space when the inner casement window is opened, which is inconvenient to hang curtains and install lifting hanging rod.
5. Good sealing and heat preservation performance. The sealing and heat preservation effect of the windows and doors is ensured by multi-point locking around the window sash.
