How to Restore Timber Sash Windows in cambridge windows and doors

Many homes in Cambridge feature traditional sash window and homeowners are proud of their appearance. However, sash windows may get stuck and be difficult to open or close. This is usually due to moisture that can cause the wood to expand.

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

1. Aesthetics

In contrast to PVC-u windows, which are constructed according to imperial sizes that are modular, timber sash windows can be restored to their original dimensions. This permits the re-installation of timber sash windows to comply with current energy standards and comply with conservation regulations for areas. It also comes with windows that are superior to upvc door repair Cost options.

Sliding sash windows were originally only used in large structures or public buildings, but this changed as production became less expensive and craftsmen could make larger frames with more glass. At the close of the 18th century, sash windows had become the most popular wooden style in British homes. 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 by the 17th century sash windows were becoming more decorative, with coloured glazing bars and moulded mullions. They were expensive at the time but as glass production became more efficient and cost-effective, they became a part of numerous period houses.

In the 19th century it was possible to make large, strong glass that did not need supporting bars. This allowed for the frame to be made larger and, in turn, gave the viewer a better view. This was a significant advancement.

The introduction of the double-hung sliding sash was another important improvement that occurred in the I920s and beginning of the I930s. The double-hung sliding sash was a important improvement that was made at the end of the I920s, and at the beginning of the I930s.

The most commonly used type of sash is constructed of slow-growing deal (pine) but oak was used in the more prestigious buildings and in some earlier examples. It is important to maintain the parting bead that separates the sashes. This will help prevent rattles and draughts. It is also important that sash pulleys and idler wheels are kept in good condition as these aid in operating the window.

2. Energy efficiency

Sash windows replaced hinged casements as larger and clearer sheets became available. They were made of plate glass, set within rebated timber frames and then pinned with glazing sprigs, and then putty on both sides to ensure they were watertight. This kind of glazing gradually replaced the use of leaded lights.

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

With regular maintenance, sash windows can be extremely energy efficient. However, without this maintenance they can become draughty and let in cold air. Draughts can also be caused by the breakdown of putty and paint. It is possible to fix this issue by using wood-to-timber products.

The industry of replacement windows is based on the perception that old windows are damaged and beyond repair, while they are able to be maintained with just a little care. These repairs can be expensive and cause many disruptions in the home. Many homeowners choose to replace their windows using PVC-u from a large ‘one-stop shop’ installation company. They can replace and remove all windows in an entire house in a single day, eliminating the need to coordinate different tradesmen and making the whole process much quicker. They can also be supplied with ‘energy saving’ double-glazing to achieve higher energy efficiency ratings than those offered by traditional windows with sash. These double glazing near me-glazed units are not capable of replicating the proportions and sections of historic timber sashes.

3. Security

Traditional windows can be secured without compromising their style. Ironmongery like mortice bolts, sash chain and sash lock could be used. They can be fitted in such a way that the window is able to be opened to allow ventilation and cleaning. These products are often not noticeable since they are designed to complement sash windows. They can be used in conjunction with traditional sash-window catches, which should be replaced with more robust versions (such as those incorporating double screws) or spring-loaded levers to minimize the possibility of them being opened by hammering.

Sash-upvc window and door repairs frames were constructed from slow-growing deal or, in more luxurious homes they were made from oak. If glazing bars have survived, they should be preserved, and if it is it is possible, the timber of the cill should be replaced with identical wood. Many PVC-U firms offer a one-stop installation service. They can take out and replace windows on a complete house in just one day, without involving any other tradespeople.

4. Ventilation

When sash windows were first introduced in the 17th century they allowed a significant amount of light to flood into the buildings. At the end of the 18th century, they were adapted to allow even more light into rooms, and larger glazing panes began to be made. The result was a lighter appearance and windows that were more elegant.

The introduction of sash windows also required the creation of a new line of ironmongery. The first pulleys were made of wood, while later Victorian ones could be made of brass or a combination of wood and lead, and there were various types of shutter hinges and knobs. These ironmongery pieces must be cleaned and preserved to appreciate their beautiful design.

To ensure they remain in good condition, wooden windows must be maintained. Lack of regular attention may result in:

Sashes that do not slide easily.

holes in the frame allow water, which can cause damage and decay.

break down of the putty and allow water penetration, which could lead to decay of the frame and cill.

In the I920s and I930s, steel casement windows grew in popularity because they were strong slim and inexpensive, and complemented the vogue for healthy living. However, research has proven that traditional softwood sash windows are as thermally efficient as double-glazed windows made of PVC-u, and can be more attractive than the sleek lines of contemporary casement windows.

The industry of replacement windows has done a lot to persuade house owners that their traditional windows are rotten, draughty and beyond economic repair. The reality is that many old windows made of timber are in good shape and with minor repairs could easily be serviceable for many years to come.

5. Maintenance

The traditional sash windows need regular maintenance and inspection. If you fail to maintain your sash window, it could cause the sash cords breaking, and the glazing bars deteriorating excessively. It can also cause paint and putty degrade. The removal of the sashes can also result in structural movement within the frame which causes the sash to move out of alignment and unable to close correctly. It is also possible for the sash be snagged or slammed into an open position and this can let water and draughts into the property.

Damage to timber windows is usually caused by moisture entry. This can be prevented by careful painting, regular repairs and elimination of the source of dampness. The paint can be removed to reveal the soft, decaying wood. Any rotten timber sections should be cut out and the affected part carefully cut or pieced with replacements made from the same kind of timber as the ones that remain. This method of repair maximizes the amount of fabric retained and is among the least invasive methods for treating timber-to-timber decay.

A wood condenser made of resin is an alternative to traditional sanding or staining. The product is brushed on the surface of the wood to protect it and stabilize it. It is particularly beneficial for the treatment of sash cords and pulleys which help prevent the breakage.

It is important to restore and not replace any old ironmongery, like the sash latches and stays. It can be difficult to replace these items without altering their original design. It is also recommended that the use of modern aluminum fittings such as sash lifts and chain stays should be avoided if possible as they can cause corrosion and deterioration to frames and sashes made from timber.
