Timber Casement Windows
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.
Traditional casement flush windows have great aesthetic merit. In addition to that, their careful design pledges to keep your home wonderfully warm, quiet and extra secure.
Our challenge was to make casement windows which look simple but are in fact very sophisticated. Hidden away is modern technology – warp resistant timber, Roto® Secured by Design locks engage in multiple points around the perimeter of every opening, ventilation grooves, drainage channels and glazing units which lose much less of the heat in comparison with ordinary windows.
