How to Restore Timber Sash Windows in Cambridge

Many homes in cambridge windows feature traditional sash window and homeowners are proud of their appearance. Sash windows can become stuck and be difficult to open or close. This is often due moisture, which can cause the timber to swell.

Box sash windows were previously operated using chains, cotton cords and lead weights. Modern sash windows feature hidden springs to overcome 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 dimensions. This permits the re-installation of timber sash windows in order to meet current energy requirements and conform to conservation regulations for areas. It also comes with windows that are superior to upvc windows cambridge alternatives.

Sliding windows with sash were initially only used in large buildings or public buildings, but this changed when production was less expensive and craftsmen were able to make larger frames with more glass. At the end of the 18th century, sash windows were the most popular wooden windows cambridge style in British homes. Since they were easy to open, sash windows let light into rooms without the need for curtains.

Early windows were simple glass but by the 17th century sash windows were becoming more attractive with coloured glass bars and moulded mullions. They were costly at first, but as glass production became cheaper and more efficient, they became a common feature in many homes of the period.

In the 19th century, it became possible to produce large, sturdy glasses that did not require supporting bars. This allowed the frame to be made bigger, which in turn gave a better view. This was an important innovation.

The introduction of the double-hung sliding sash was a significant improvement that came about in the I920s and the beginning of the I930s. The double-hung sliding sash was a significant improvement that came about at the end of the I920s and at the beginning of the I930s.

Oak was used in older and more luxurious buildings. A parting bead separates the two sashes, and it is essential that it is maintained to prevent rattles and draughts. It is also essential that sash pulleys and idler wheels are kept in good shape as they assist in operating the window.

2. Energy efficiency

Sash windows replaced hinged casements as larger and clearer sheets were made available. Glass plates were set in rebated timber frames, pinned with glazing sprigs and putty was sprayed on the frame's two sides to ensure watertightness. This kind of glazing gradually replaced leaded lights.

The introduction of sashes resulted in the need for a larger variety of ironmongery including the most basic fittings, brass pulleys, lead (and later cast iron) weights, sash stoppers shutter hinges and knobs as well as a range of fasteners that secured the sashes into the right place. These were often decorated in motifs, inscriptions, and engravings to identify the maker.

With regular maintenance, sash windows can be extremely energy efficient. If they are not maintained they can get drafty. Putty and paint can cause draughts too. This can be remedied by using proprietary wood-to-timber repair products.

The replacement window industry relies heavily on the notion that older windows are beyond repair and cannot be maintained economically. However, they can easily be maintained with a little attention. However, these repairs can be costly and cause substantial disruption to the home. Many homeowners opt to replace their windows using PVC-u from a "one-stop shop" installation company. They can take down and replace all the windows in a home within a single day, avoiding the need to coordinate multiple tradesmen and making the entire process much faster. These windows can be equipped with energy-saving double glazing to get more energy efficient ratings than a traditional windows with sash. However, these double-glazed units cannot replicate the section and proportions of historic timber sashes.

3. Security

It is possible to secure windows that are traditional without compromising their style. Ironmongery like mortice bolts, sash chain and sash lock could be installed. They can be fitted in a way so that the window can still be opened to allow ventilation and cleaning. These products are often discrete since they are made to complement sash windows. They can be used with traditional sash window catches. These are best replaced with more robust versions, such as ones that have double screws or sprung levers, to minimize the possibility of being hit with hammers.

Sash-window frames are traditionally constructed from oak or slow-grown deal. If the glazing bars are still in good condition and in good condition, they should be kept. Where it is possible, the cills of the timber should be replaced with wood that is in line with. Many PVC-U firms offer a one-stop shop installation service. They can take out and replace windows on a complete house in just one day, without the need to involve other tradespeople.

4. Ventilation

When sash windows were first introduced in the 17th century, they allowed a significant amount of light into buildings. By the end 18th century, they were modified to allow more light could be let into the rooms. Larger glazing panes were also made. The result was a much lighter appearance, and windows with a higher quality of design than before.

The introduction of sash windows also required an entirely new range of ironmongery. Early pulleys were made from 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. The ironmongery pieces need to be cleaned and preserved to appreciate their beautiful design.

To keep them in good condition, wooden windows need to be maintained. Lack of regular attention may cause:

Sashes that do not move smoothly.

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

break down of putty, allowing water to penetrate, which could cause decay in the frame and cill.

In the I920s and I930s, steel casement windows grew in popularity because they were strong slim and affordable and also matched the fashion for healthy living. However, research has shown that traditional softwood sash windows can be just as thermally efficient as double-glazed PVC-u windows and can be more attractive than the sleek lines of contemporary casement windows.

The window replacement industry has made a significant effort to persuade house owners that their old windows are rotten, draughty and beyond economic repair. Many old windows made of timber can be repaired and used for a long time with minor repairs.

5. Maintenance

The traditional sash windows need regular maintenance and inspection. If you don't maintain your window's sash, it could result in the sash cords breaking and the glazing bars deteriorating excessively. It can also cause paint and putty to degrade. The removal of sashes can also result in structural movement within the frame which causes the sash to move out of alignment and in a position that it is not able to close properly. The sash may also become stuck in its open position, which allows water and draughts into the building.

Moisture penetration is a common cause of damage to windows made of timber. This can be avoided by thorough painting, regular repairs, and removing the cause of dampness. Wet rot can be identified by the wavy appearance of the paint, which can be stripped to reveal rotting, soft timber. The rotten timber sections should be carefully removed and the affected part should be scarfed or glued together using replacements of the same nature as the rest of the timber. This method of repair maximizes the amount of fabric retained and is among the least invasive ways of treating decay caused by timber.

The use of a resin-based wood consolidant is another alternative to the traditional method of staining and sanding. This is brushed onto the surface of the wood to stabilise and shield it from further damage. It is especially beneficial to treat pulley cords and sash which can help prevent breakage.

It is essential to preserve and not replace any old ironmongery, like stay latches and sash latches. These items are difficult to replace without compromising the the original design. It is also recommended that the use of modern aluminium casement windows cambridge fittings, such as chain stays and sash lifts is avoided if at all possible since they can cause corrosion and deterioration of frames and sashes made of timber.
