Many homes in cambridge replacement windows have traditional sash windows and homeowners are proud of the way they appear. However, sash windows can get stuck and be difficult to open or close. This is often due to moisture that can cause the timber to swell.

Box sash windows were historically operated using chains, cotton cords and lead weights. Modern sash windows feature hidden springs to overcome this issue.

1. Aesthetics

Timber sash windows, in contrast to PVC-u windows that are made in imperial sizes, which are modular, can be reconstructed to their original size. This permits the re-installation of timber sash windows to meet the current energy requirements and conform to conservation regulations for areas. It also comes with windows that are superior to the upvc door repair options.

Sliding sash windows were initially only found in large buildings or public buildings, however this changed when production became less expensive and craftsmen could produce larger frames with more glass. At the end of the 18th century, sash windows were the most sought-after wooden style in British homes. Sash windows were simple to operate and allowed light to enter rooms without the use of curtains.

The first windows were made of plain glass but by the 17th century sash windows started to become 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 were a common feature in numerous period houses.

In the 19th century, it was possible to make large, strong glasses that did not require supporting bars. This allowed for the frame to be made larger, which in turn gave the viewer a better view. This was a very important advancement.

The introduction of the double-hung sliding sash was another important improvement that occurred at the end of the I920s and at the beginning of the I930s. The double glazing repairs near me-hung sliding sash was a significant improvement that came about at the end of the I920s, and at the beginning of the I930s.

The most commonly used type of sash is constructed from slow-growing deal (pine) however oak was used in the more luxurious buildings and in earlier examples. It is important to maintain the parting bead that separates the sashes. This will help prevent draughts and rattles. It is also crucial that sash pulleys and idler wheels are in good working order as they assist in operating the window doctor.

2. Energy efficiency

Sash windows were replaced by hinged casements as clearer and larger sheets became available. They were glazed with plate glass set in timber double glazed windows cambridge frames with rebates and then pinned with glazing sprigs, and then putty on both sides to make them watertight. This type of glass gradually replaced leaded lights.

Sashes were introduced, which resulted in increased demand for ironmongery. The most basic fittings were brass pulleys (and later cast-iron) weights, sash stoppers shutter hinges and handles and various fasteners used to fix the sashes. These were often decorated with motifs, inscriptions or engravings that identified the maker.

With regular maintenance, sash windows are very energy efficient. However, without this maintenance they may become drafty and let in cold air. Draughts can also be caused by the breakdown of paint and putty. You can fix this problem by using wood-to-timber solutions.

The market for replacement windows is based heavily on the perception that old windows are beyond repair and cannot be maintained economically. However they can be maintained with a bit of attention. However, repairs to these windows can be costly and cause considerable disruption to the home. To prevent this, many homeowners prefer to replace their windows with PVC-u windows made by one of the large "one-stop shop" installation companies. They can replace all windows in a home in one day, thereby saving time and eliminating the need for various tradesmen to coordinate. They can also be supplied with energy-saving double-glazing to get more energy efficient ratings than those offered by traditional windows with sash. However these double-glazed units are unable to duplicate the proportions and section of traditional timber sashes.

3. Security

It is possible to secure windows that are traditional without compromising their style. Ironmongery like sash chain, mortice bolts, and sash lock can be used. They can be positioned in a manner that the window is able to be opened to allow ventilation and cleaning. They are generally not noticeable, since they are designed to match the sash window. They can be used in conjunction with traditional sash window catches. They should be replaced with more robust models, such as those that incorporate double screws, or sprung levers, to minimize the risk of being struck by hammers.

Sash-window frames are usually made of oak or slow-grown deal. If the glazing bars are intact and in good condition, they should be kept. Where it is possible, the cills of the timber should be replaced by wood that matches. Many PVC-u firms offer a one-stop installation service. They can take down and replace windows on an entire home in one day, without involving any other tradespeople.

4. Ventilation

When sash windows were first introduced in the 17th century, they allowed a substantial amount of light into the buildings. By the end 18th century, they were adapted so that even more light could be let into the rooms. Larger glass panes were also made. The result was a lighter appearance and windows with a higher quality of design than before.

The introduction of sash windows also required a new range of ironmongery. The first pulleys were made of wood, whereas later Victorian ones were made from brass or a mixture of wood and lead, and there were various types of shutter hinges and knobs. Ironmongery elements must be maintained and cleaned so that the fine quality of their design can be appreciated.

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

Sashes that do not slide smoothly.

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

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

In the I920s and the I930s steel casement windows increased in popularity because they were strong, slim and cheap and also matched the fashion for healthy living. Studies have shown that softwood sash windows are just as effective as PVC-u windows, and may even be more attractive.

The replacement window industry has done a great job convincing homeowners that their old windows were decayed drafty, noisy and beyond repair. Many old windows made of timber can be repaired and used for many more years with minor repairs.

5. Maintenance

The traditional sash windows require regular maintenance and inspection. If you fail to maintain your sash window, it can cause the sash cords breaking and the glazing bars deteriorating excessively. It could also cause paint and putty deteriorate. The removal of sashes can also result in structural movement within the frame, which can cause the sash to not close properly. The sash could also get stuck in the open position, allowing the water and drafts to enter the property.

Moisture penetration is a common cause of damage to windows made of timber. This can be prevented by careful painting, regular repairs, and removing the source of dampness. Wet rot can be identified by the wavy look of the paint that can be stripped to reveal rotting, soft timber. The sections that are rotting should be carefully cut out, and the affected area should be snared together or glued together by using replacements of the same nature as the rest of the timber. This method of repair maximizes the amount of original fabric that is left and is one of the least invasive ways of treating decay caused by timber.

A wood condenser that is based on resin is a viable alternative to traditional staining or sanding. The product is brushed on to the surface of the timber to stabilise and protect it from further damage. It is especially beneficial for the treatment of pulley cords and sash which can stop breakage.

It is important that any historic ironmongery such as sash stay and latches be kept and restored instead of replacing them. It is difficult to replace these items without altering their original design. It is also recommended that the use of modern aluminum fittings like sash lifts and chain stays is avoided if at all possible as they can cause corrosion and deterioration to timber frames and sashes.
