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.
