In other words, the window can be opened a little from the top, and the opened part is suspended in the air and connected and fixed to the window frame by hinges, etc., so it is called top-hung type. Its advantages are: it can ventilate and ensure safety. Because of the hinges, the window can only open a gap of ten centimeters, and hands cannot be reached from the outside, which is especially suitable for use when no one is at home. This function is not only limited to casement windows, but also sliding windows can be opened in a top-hung style.

Side hung door

One-way opening means that the door can only be opened in one direction (can only be pushed inward or pulled outward), and two-way opening means that the door leaf can be opened in two directions (such as spring doors). Side hung doors are divided relative to other opening methods, because there are also doors that can be opened by moving, flipping, rolling up and down, vertically lifting, rotating, etc.
