Traditionally, windows made of box sash utilized chains or cotton cord and weights made of lead to operate. Modern sash windows have hidden springs to overcome this issue.

1. Aesthetics

Timber sash windows, in contrast to PVC-u windows that are made in imperial sizes that are modular, can be restored to their original size.

Sliding windows with sash were initially only found in large buildings or public buildings, though this changed when production became less expensive and craftsmen could make larger frames with more glass. At the close of the 18th century, sash windows were the most popular wooden style in British homes. Since they were easy to open sash window repair cambridge windows allowed light into rooms without the need for curtains.

Early windows were plain glass but by the 17th century, sash windows started to become more decorative, with coloured glazing bars and moulded mullions. These were very expensive at the time but as glass production improved and cheaper they became a feature of many of the period homes.

In the 19th century, it became possible to produce large, strong glasses that did not require supporting bars. This allowed the frame size to increase more, which in turn allowed for a wider view from the window. This was an important innovation.

Another important 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 lower and upper sash to be opened simultaneously, and also improved the ventilation of a building.

Oak was used in older examples and more prestigious buildings. It is important to maintain the parting bead that separates the sashes. This will prevent rattles and draughts. The sash pulleys, idler wheels and sash rollers also are essential to the functioning of the window.

As larger and clearer glass sheets became available, sash window began to replace hinged casements. Plate glass was set into rebated timber frames, pinned with glazing sprigs and putty was then sprayed onto both sides of the frame to ensure watertightness. This form of glazing gradually superseded leaded lights.

The introduction of sashes created the need for a greater variety of ironmongery, including the most basic fittings, brass pulleys as well as lead (and later cast iron) weights, sash stops shutter hinges and knobs, and a range of fasteners to hold the sashes into the right place. These were often decorated with motifs, inscriptions, and engravings that identified the maker.

With regular maintenance, sash windows can be very energy efficient. If they are not maintained, they can become draughty. Draughts can also be caused by the breakdown of putty and paint. This can be fixed by making use of wood-to-timber repair tools that are proprietary.

The market for replacement windows is based heavily on the perception that older windows are beyond repair and are not able to be maintained economically.

These windows can be equipped with energy-saving' double glazing to achieve more energy efficient ratings than a traditional windows with sash. Double-glazed windows aren't able to replicate the proportions and sections of sashes from old timber.

3. Security

Traditional windows can be secured without compromising their appearance. Ironmongery such as sash chain, mortice bolts and sash lock could be put in place. They can be fitted in a manner that the window can be opened to allow ventilation and cleaning. They are usually discrete since they are made to be used in conjunction with sash windows. They can be utilized in conjunction with traditional sash window catches, which must be replaced by more robust versions (such as those incorporating double screws) or spring levers to decrease the possibility of them being opened by hammering.

Sash-window frames are typically constructed from oak or slow-grown deal. If the glazing bars are intact and are not damaged, they should be left. If it is feasible, the cills made of timber should be replaced with wood that is in line with. PVC-U companies usually provide a one-stop shop installation service, removing and replacing windows on an entire home in a single day without the need to involve other tradespeople, or coordinate visits from a number of different suppliers.

4. Ventilation

Sash windows were first introduced in the 17th century and allowed for a significant amount of light to enter buildings. In the 18th century, they were adapted so that even more light could be let into the rooms. Larger glazing panes were also produced. The result was a lighter look and windows with more elegance.

Sash windows were introduced and required a new range ironmongery. Early pulleys could be made from wood. Later Victorian ones were made of brass or a mixture of wood and lead. There were also various types of knobs and shutter hinges. These ironmongery pieces must be kept clean and preserved in order to appreciate their beautiful design.

To keep them in good shape, timber windows must be maintained. Lack of regular attention may cause:

Sashes that do not move easily.

holes in the frame that admit water that can cause decay and damage.

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

Steel casement windows became popular in the I920s & I930s due to their strength and slim, cheap and complemented the trend for healthy living. However, research has proven that traditional softwood sash windows can be just as thermally efficient as PVC-u double-glazed windows, and may be more appealing than the modern sleek design of casement windows.

The reality is that many old timber windows are in good condition and, with minor repairs, could easily be maintained for years to come.

Failure to do this can lead to sash cords breaking, excessive wear on the glazing bars, and degradation of the paint and putty. The removal of sashes can also cause structural movement in the frame, which can cause the sash not to close correctly. The sash may also become stuck in an open position, allowing water and draughts into the building.

Moisture penetration is the most common cause of damage to timber windows. This can be prevented with thorough painting, regular repairs and the elimination of the source of dampness. Wet rot can be identified by the wavy look of the paint, which can be stripped away to reveal soft, rotting timber. Any rotten sections of timber must be removed and the affected part carefully scarfed or pieced in using replacements made from the same type of timber as those remaining. This method of repair maximizes the amount original fabric and is among the most non-invasive methods to treat wood-to-timber rot.

A wood condenser that is based on resin is a viable alternative to traditional sanding or staining. It is brushed onto the surface of the wood to protect it and stabilize it. It is particularly beneficial in the treatment of pulleys and sash cords which help stop breakage.
