Introduction:

A style of windows in folk houses. The opening and closing of window sash is moving along a certain horizontal direction, so it is called "casement window".
Casement windows are divided into push-pull type and hanging type. Its advantages are large opening area, good ventilation, good sealing, sound insulation, heat preservation and impermeability. The inside opening window is convenient to clean, and the outside opening window does not occupy space. The disadvantage is that the window is small and the field of vision is not wide.
The opening of external windows takes up a space outside the wall, which is easy to be damaged when the wind blows; while the opening of internal windows takes up part of the indoor space, so it is not convenient to use the screen windows, and it is also not convenient to use the screen windows and curtains when opening the windows. If the quality is not up to standard, it may also seep rain.
