−	Casement windows usually open from the inside outwards and, depending on the design, can offer a full opening for maximum ventilation, as well as allowing a person to lean out. This can also free-up space inside (compared to opening inwards) and may better direct air inwards for ventilation.

	The frame of a casement window may be divided vertically (with mullions) or horizontally (with transoms) or feature both. The sash or sashes will fit within the frame and be either top-, side or bottom-hinged. Side-hung sashes are usually fitted on butt hinges or easy-clean hinges which allow access to the outside of the glass from the inside. It is quite common to see a central mullion dividing the window frame in two: one half will feature a side-hung sash while the other will have a transom to create a smaller top-hung sash useful for trickle ventilation (see photo).

Casement is a term that is also applied to doors.

A casement door is similar in concept to a casement window: a hinged single sash (opening door leaf within a frame) or a dual sash to result in what is usually referred to as a ‘French door’. French doors are casement doors which are semi- or fully-glazed and used widely throughout Europe as a means to connect the inside with the outside, often a patio, garden, grounds, deck or balcony.

Casement doors are available in the same materials used for casement windows, i.e wood, PVC, aluminium etc.
