Sliding frames for windows made of sash were originally only used for large buildings or public buildings. However the production became less expensive and craftsmen could make larger frames using larger glass.

Early windows were simple glass, but in the 17th century, sash windows began to become more attractive with coloured glass bars and moulded mullions. They were expensive initially, but when glass production became less expensive and more efficient, they became an integral feature in many period houses.

In the 19th century, it was possible to make large, sturdy glass that didn't require supporting bars. This allowed the frame to be made larger which, in turn, provided a better view. This was a significant innovation.

Another significant improvement was the introduction of the double-hung sliding windows at the end of the I920s and beginning of the I930s. This allowed both the upper and lower sash to be opened at the same time and also improved the ventilation of a building.

As larger and clearer glass sheets became available, sash windows began to replace hinged casements. They were made of plate glass, set in timber frames with rebates and secured with glazing sprigs, and then putty on both sides to create a watertight seal. This type of glass gradually replaced leaded lights.

Sashes were introduced, which led to increased demand for ironmongery. The most common fittings included brass pulleys (and later cast-iron) weights and stoppers for sashes, shutter hinges and handles as well as a variety of fasteners to secure the sashes. These were often decorated with motifs, inscriptions, and designs that were engraved to identify the maker.

Sash-window frames are usually made of oak or slow-grown deal. When glazing bars have survived they should be kept and, if feasible, the wood of the cill should be replaced with matching wood. PVC-U companies usually offer a one stop shop installation service, which includes removing and replacing windows across a home in a single day without the need to engage other tradespeople, or coordinate visits from a number of different suppliers.

4. Ventilation

When sash windows first introduced in the 17th century, they allowed a significant amount of light to flood into buildings. At the end of the 18th century, they were modified so that more light could be let into rooms. Larger glass panes were also produced. The result was a more light appearance and windows that were more elegant.

Sash windows were introduced and required a new type of ironmongery. Early pulleys could be made out of wood. Later Victorian ones were made of brass or a mixture of wood and lead. There were also different kinds of shutter hinges and knobs. These ironmongery pieces should be kept clean and preserved in order to appreciate their fine design.

Timber windows require careful maintenance to ensure they remain in good shape. A lack of regular attention can result in:

Sashes that don't slide smoothly.

Holes in the frame that allow water to enter and cause decay and damage.

Water can penetrate the putty and cause decay to the frame or cause cill.

Moisture penetration is a common cause of damage to timber windows. This can be avoided with regular repairs by thorough painting and eliminating the source of dampness. Wet rot can be identified due to the wavy appearance of the existing paint which can be stripped away to reveal soft, rotting timber. The sections of timber that are rotten must be removed with care, and the affected area should be snared together or pieced together with replacements of the exact nature as the rest of the timber.
