How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge have sash windows that are traditional and the homeowners are proud of their appearance. Sash windows can get stuck and are difficult to open and close. This is usually due to moisture which can cause the wood to swell.

Traditionally, windows made of box sash used chains or cotton cords and lead weights to operate. Modern sash windows come with hidden springs to address this issue.

1. Aesthetics

Unlike PVC-u windows that are made to modular imperial sizes the timber sash windows are able to be restored to their original sizes. This allows the restoration of timber sash windows in order to meet current energy requirements and conform to conservation area regulations. It also provides windows that have a more attractive appearance than upvc window lock repair alternatives.

Sliding sash window installation cambridge (webpage) frames were initially only used in large buildings or public buildings. However the production became more affordable and artisans could create larger frames using greater glass. In the 18th century, sash windows were the dominant wooden style in a majority of British properties. Sash windows were easy to operate and let light in rooms without the use of curtains.

The first windows were made of plain glass, but in the 17th century, sash windows started to become more decorative with coloured glazing bars and moulded mullions. They were expensive at first, but as glass production became less expensive and more efficient, they were a common feature in many homes of the period.

In the 19th century it was possible to create large, strong glass that did not require support bars. This allowed the frame's size to be increased even further, which gave a better view out of the window. This was an important advancement.

Another important improvement was the introduction of the double-hung sliding window at the end of I920s and at the beginning of I930s. This allowed both the lower and upper sash to be opened at the same time and allowed for better ventilation to a building.

The most commonly used kind of sash is made from slow grown deal (pine) but oak was utilized in more luxurious buildings and in some earlier examples. A split bead divides the two sashes and it is essential that it is maintained in order to avoid rattles and draughts. The sash pulleys, idler wheels and sash rollers are also vital to the operation of the window.

2. Energy efficiency

As larger and clearer glass sheets were made available, sash windows began replacing hinged casements. Plate glass was set into rebated timber frames, which were pinned with glazing sprigs, and putty was applied to both sides of the frame for watertightness. This type of glazing gradually replaced the leaded light bulbs.

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

With regular maintenance, sash windows are very energy efficient. Without this maintenance they can get draughty. Putty and paint can cause draughts too. This can be fixed by making use of wood-to-timber repair tools that are proprietary.

The market for replacement windows rests on the belief that traditional windows are rotten and beyond economical repair, whereas they can be easily maintained with a little attention. However, repairs to these windows can be expensive and involve substantial disruption to the home. To avoid this homeowners, many choose to replace their windows with PVC-u windows from one the largest 'one stop shop' installation companies. They can replace all windows in a home in one day, thereby saving time and avoiding the need for various tradesmen to coordinate. These windows can be equipped with energy-saving double glazing to get higher energy ratings than traditional windows made of sash. However these double-glazed units are unable to duplicate the proportions and section of traditional timber sashes.

3. Security

Traditional windows can be made secure without compromising their appearance. There are many types of ironmongery that can be fitted with sash chains, mortice bolts, and sash locks. They can be fitted to ensure that the window is still open to allow ventilation or cleaning. These are typically minimal in appearance, as they are designed to match the sash window. They can be used in conjunction with traditional sash window catches. These are best replaced with more robust models, such as those that incorporate double screws, or sprung levers in order to reduce the possibility of being hammered.

Sash-window frames are usually made from oak or slow-grown deal. If glazing bars have survived, they should be kept, and if it is possible, the timber of the cill should be replaced with the same wood. PVC-U companies usually provide a one-stop shop installation service, which includes removing and replacing windows across a house in a 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 huge amount of light to enter buildings. By the end of the 18th century they were altered to allow even more light into rooms and larger glass panes began to be manufactured. The result was a lighter look and windows that were more elegant.

Sash windows were introduced that required a brand new range ironmongery. The first pulleys were made of wood, while later Victorian ones were made of brass or a combination of lead and wood, and there were various types of shutter hinges and knobs. The ironmongery pieces need to be cleaned and preserved to appreciate their beautiful design.

To ensure they remain in good condition, timber windows need to be maintained. A lack of regular attention can result in:

Sashes that do not slide easily.

holes in the frame that allow water causing damage and decay.

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

Steel casement windows gained popularity in the I920s & I930s because they were sturdy and slim, cheap and matched the trend towards healthy living. However, research has shown that traditional softwood sash windows are just as efficient in thermal efficiency as double-glazed PVC-u windows and can be more attractive than the modern sleek design of casement windows.

The replacement window industry has made a significant effort to convince homeowners that their old windows are dirty, noisy and beyond economic repair. The reality is that many old timber windows are in good condition and, with minor repairs, could easily be repaired for many years to come.

5. Maintenance

A traditional sash window requires regular maintenance and inspection. If you fail to maintain your sash window, it can result in the sash cords breaking, and the glazing bars wearing out excessively. It can also cause paint and putty deteriorate. The removal of sashes could also result in structural movement within the frame that causes the sash to become misaligned and in a position that it is not able to close properly. It is also possible for the sash be snagged or slammed into an open position, which can let water and draughts in the structure.

Damage to timber windows is often caused by water entry. This can be avoided with regular maintenance by thorough painting and eliminating the source of dampness. The paint can be removed to expose the soft, decaying wood. Any timber that is rotting should be cut out and the affected area should be carefully wrapped or pieced back using replacements made of the same type of wood as those remaining. This method of repair increases the amount of original fabric retained and is one of the least invasive methods of treating decay of timber to timber.

A wood condenser made of resin is an alternative to the traditional process of sanding or staining. The product is brushed on the surface of the wood to protect it and strengthen it. It is especially beneficial for the treatment of pulley cords and sash, which can stop breakage.
