windows

A window includes the frame and one or more sashes which are glazed……..sashes which are made to open like a door are called casements, and window is usually specified as a casement window. W.B.McKay

The word casement is properly used to describe the framing material and glass of a side hung window. The frame material for other opening lights is termed a sash.Barry’s - ‘introduction to construction of buildings’.

Casement windows – these are main or common types of windows usually provided in buildings. The shutters of the window open like shutters of the door.

Sash windows – a sash window is a type of casement window in which the panels are fully glazed.
