The origins of the sash window are believed to be in England in the 1670’s. This style of window and method of operation has retained its popularity since that era, both in restoration of historic homes and in new construction.

A sash refers to a panel of glass (or today it could be plastic) that is set as one or more panes of material into a frame which slides up and down, or side to side, to open a room to the outside or shield its interior from the weather.

Robert Hooke, a brilliant man born in England in the 1600s, was both a practical man skilled in clock making and surveying, a skilled architect, a biologist, and a physicist. He studied gravity, the properties of glass, and invented a balance spring that led to the development of the watch. It is easy to see how these studies contributed to his window, moving up and down with a weight to offset the pull of gravity, with muntins (strips of wood holding individual panes of glass in a frame) to relieve stress on the amount of glass needed for large panels, and attractive enough to grace a stately home.

Over time, sash windows made of wood will loosen in their frames, as continual opening and shutting wears the jambs and tracks, and the wood itself expands and contracts with the changing seasonal temperatures and shows the effects of weather. Older windows may rattle in the wind and let air leak in or out around the joints. They also may refuse to open as paint builds up in the seams, or refuse to stay pushed up when the sash cords get brittle and break with age.

Repairing these old windows is an option that many choose, since a handy homeowner with simple tools and a vast amount of patience can do the job. Others wish to retain as much of the original structure as possible when renovating an historic property. Replacement is an option as well, as many reproduction windows are manufactures out of traditional materials, and custom woodworking mills can make exact replicas of old designs.

The sash window has not been changed much over the years, although single glazing has often given way to double and even triple glazing for energy efficiency. Glazing is a term for a transparent panel in a wall; single means one thickness, while double and triple glazing simply fist more than one panel in a frame, with air spaces in between.

The origins of the sash window are fun to trace, as are the changes, not so much in design as in materials. Today’s windows may be made of soft or hard wood, metals such as aluminum and vinyl, and even fiberglass.

Respiratory problems, such as lung cancer, can be blamed on asbestos, a common material used for insulation. Sash windows were at one time, produced with lead based plastic. The lead in the window would break down over time an release into the air. But no more. This is great news.

This lead residue could be inhaled and cause many health problems. Today though, sash window manufacturers are using, instead of lead, calcium organic stabilizers. The calcium based stabilizers still offer the same durability as lead based products, but this compound is much safer. This a great development.

In addition to using non lead based products, many sash window companies are using recycled materials in their window manufacturing. This also insures that a lot of dangerous building material will not end up in the landfills and make it into the ground and into well water systems.

The origins of the sash window are not easy to fathom. There are a variety of theories but no absolute proof for any of them. In the late 1600’s, an English inventor, Robert Hooke used them in Ham House and a painting by Vermeer called ‘The Milkmaid’ shows a sash frame behind the girl. It is believed that they might have come from France, via Holland to Britain around this time but the British certainly made them their own.

Windows with double rows of glass panes that opened by sliding to one side or upwards, were initially known as ‘Yorkshire light’. As the windows became larger and heavier, a rope and sash weight system was developed with the rope connected to the window and a pulley running inside the sealed box frame.

In the late 1600’s, the famous architect Sir Christopher Wrens used these windows for Whitehall Palace. They were also used for Kensington and Hampton Court Palace. Wrens’ reputation and the royal patronage gave wooden sash windows a cachet that soon saw them used right across the British empire. Until the early 1900’s, the windows were used almost exclusively in all new constructions both private and public. Whether open or closed they do not detract from the aesthetics of a building unlike other windows.

The double hung sash window which can be opened at the top and bottom were a feature designed during the Georgian era. European weather can range from very wet and cold to very hot during summers. An opening at the top lets hot air escape, while opening the bottom draws in cool air and prevents rain from getting in.

The Victorians had a tendency to the baroque, overloading their houses with extra details, carvings, mouldings and lattice work. The windows were grouped in a bay surrounded by decorative pillars. The perspective of buildings was enhanced by making windows on the downstairs floor taller than those on the top floors.

The sash window was doomed with the advent of the 20th Century. The rapid industrialisation of production processes caused by the demand for machinery and weapons in the First World War, put an end to expensive hand-crafted methods involving much time and labour.

Many older European buildings and cities would be characterless without these beautiful windows, which remain popular even though they cause problems.
