klaffuppsättning

Klaffuppsättning refers to a type of window construction. It is a term used to describe the way the movable parts of a window, known as sashes, are configured within the frame. Specifically, it denotes a window where one sash is fixed and the other is operable. This fixed sash remains in place, providing light and insulation, while the movable sash can be opened, typically by sliding vertically or horizontally, to allow for ventilation. The term originates from Swedish and can be translated roughly as "flap setting" or "sash arrangement." This design is often chosen for its simplicity and cost-effectiveness compared to windows with multiple operable sashes. It is a common feature in older buildings and can still be found in modern construction where specific aesthetic or functional requirements are met. The term is primarily used in contexts related to window manufacturing, installation, and historical building analysis.
