Flush Casement Window

Historically, casement windows (also known as cottage windows) were already in use in the 16th century in Britain. They succeeded the stone mullioned window and pre-dated sash box windows. Subdivided by glazing bars that joined together the small panes of glass, the earlier designs had the opening part of the window - the ‘casement’ - made of iron with lead latticing to the glass. By the beginning of the Victorian period, the frames and opening casements were made entirely of timber. Windows of 6-panes per casement were the most common pattern, but designs were occasionally elaborated by the use of Gothic arches or smaller panes, depending on the fashion in certain parts of the country.

The traditional flush timber casement became the most common window type by the second half of the 18th  century. Casement windows started their career mainly in farmhouses and cottages. However, they abounded in palaces and wealthy households as well. Obviously, like anything else, the features of casement windows have developed over time, too. Initially, in Georgian era, only small glass panes were used. As the technology of producing glass developed and improved, so the panes of glass became bigger. Subsequently, the number of panes per casement was reduced to two with one horizontal glazing bar. However, smaller pane sizes become popular again in the Edwardian era. There are different types of casements and one of the more recognisable is one with leaded lights in different configurations. The panes can be square, rectangle, diamond, round, tipcat and other. It just testifies to the fact that, say what you will, but casement windows simply cannot be boring! They are smart, practical and attractive. They are flexible in a way that would suit every type of house, no matter what its style, periodic or modern.
