Casement Sash Windows

Windows are an intrinsic part of our built environment. Not only do they admit light to an interior and permit views to the outside world, they also comprise the public face of a building and help shape how a facade expresses itself. A wander along a typical Irish street can be a feast for the eyes, highlighting the way in which windows are arranged in an elevation, their glazing patterns and detailing, and their opening format — such as sash or casement — all contribute to our collective national architecture that makes us part of who we are and makes our buildings look the way they do. This is especially true of Ireland, where most traditional street architecture and vernacular buildings depend upon basic classical rules of proportion and detailing for their architectural effect, rather than applied decoration that is commonplace in other countries. This requires understanding and careful management, as if the subtle balance of proportion and detail of historic windows is upset or discarded, the harmony and integrity of our built heritage can be irreplaceably eroded. We often take the appearance of our buildings for granted, however all structures are shaped by a number of factors — whether environmental, functional, economic, fashion or others — and this is also true of windows. Symmetrically positioned windows, centrally placed doors, tall rectangular window opes, and elegantly designed window glazing that mirrored the proportions of the building, all became commonplace. Likewise, the availability of technology, such as new developments in glass-making, determined how windows were glazed in certain parts of the country compared with others, while local fondness for a particular type of detail resulted in delightful regional variations within the classical canon of window design. Fashion and functionality also went hand-in-hand, ensuring that the reliable sliding sash was the dominant window type in Ireland for years, with casements only making some headway by the late nineteenth-century as picturesque notions and international influences began to encourage change. A large glazed opening in a wall allowing light to an interior is a relatively modern innovation in Ireland, as limited glass-making technology and the practical need for defence militated against such extravagance until the seventeenth century.

Sash window horns are residues from our past that have remained, changed, and evolved into the shapes and sizes we see today. Following them through history is like following many other inventions, a brilliant mind coming up with a great idea, implemented all over the country, superseded by emerging technology, and left as a relic to our all-too-common human story of progress. The Sash window is more than hundred years old, and it has been used throughout the Georgian, Victorian, and modern eras.

The horns were invented around when double-glazed windows were starting to become popular — the glazing bar which was mostly made out of moulded wood had to be removed to make way for the installation of the extra glass panes. This made the extra frames weak and susceptible to damage, so these curious horns were invented in a smart fit of engineering to reinforce the frames and make them withstand the extra weight better. There are probably several factors which helped these little horns overtake virtually every window frame in the UK:.

Progress was also made in producing glass — we have and install triple-glazed windows in our homes.

An important element of the French sash window was the use of glass set in the timber glazing bars.

Before their introduction, the use of leaded lights had been universal. Pane size was based on the Golden Section at a ratio of 5 parts wide to 8 parts high, which was devised in ancient Greece as a harmonious proportion based on the human body. Occasionally the structural opening was also based on the Golden Section but proportions based on the cube were also important, sashes most typically being one and three quarters parts high to one part wide.

Glazing bars gradually reduced in width to less than 15 mm in the 19th century.

The true origin of the sash window is something that is still open to debate but various theories have been put forward. Generally, it was thought that they were invented in Holland in the late 17th Century, but more recently it has been suggested that they could have been invented earlier in the 17th Century in England, most likely in Yorkshire. What is clear is that sash windows were used in some of the finest houses of England with examples including Chatsworth House, Kensington Palace and Hampton Court Palace.

Sir Christopher Wren adopted their use which helped to establish them as fashionable status symbol across Britain. This spread to use in Colonial lands as the British Empire exported the style.

The casements themselves side hinged, outward opening sections of the window , were usually limited in size. The only method of regulating the temperature of an Elizabethan house was by perpetually opening and closing the casement, each time lodging its long handle on the fixed pegs along the window frame.

Then along came the invention of the sash window, comprising one or more movable, glazed panels sashes , usually vertically sliding. First introduced in the mid s, the sash window literally came as a breath of fresh air to the medieval home. With the ability to open the window top and bottom, a home could now be far more efficiently ventilated warm stale air could escape through the top sash, cooler fresh air could enter through the bottom , and the temperature could be regulated by altering the height of each sash opening accordingly, and with little effort.
