Screen Integrated Aluminum Swing Doors

Swing and Casement Introduction:

Swing and Casement’ is a term usually associated with windows and denotes a window with a glazed 'sash' that is hinged at the sides (side hung), or at the top (top hung) or at the bottom (bottom hung). The parts that open are therefore separate from the frame and are referred to as hinged sashes. This is in contrast to what traditionally would have been called sliding ‘sash windows’, where opening is achieved by a vertically sliding ‘sash’ that moves within the frame.

Casement windows were used before the advent of the sliding sash window which only appeared in the early Georgian period. Before this, casement windows (often with latticed lights) were the predominant window type.

Casement windows usually open from the inside outwards and, depending on the design, can offer 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. Typically, if the hinges are on the right of the sash, the locking mechanism will necessarily be on the left, and vice-versa.

In recent years, casement windows in the UK have become more popular than sliding sash windows because they are less complex (no need for hidden cords, pulleys and weights), more economical, have more compact frames, close more tightly, and are easier to manufacture and assemble. Their popularity has spread in part thanks to the marketing activities of replacement window companies which typically replace sliding sash windows with casements.
