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 become difficult to open or shut. This is usually due to moisture, which can cause the wood to expand.

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

1. Aesthetics

Unlike PVC-u windows that are manufactured according to the modular imperial size the timber sash windows are able to be restored to their original size. This allows for the restoration of timber sash windows to meet the current energy requirements and to comply with conservation area regulations. It also gives a window with a far superior appearance than the uPVC alternatives.

Sliding sash window frames were initially only used for large buildings or public buildings. However this changed as production became cheaper and artisans could make larger frames using more glass. At  window repair cambridge  of the 18th century, sash windows were the most popular wooden style in British homes. As they were easy to open sash windows allowed light into rooms without the need for curtains.

The first windows were made of glass that was plain however, in the 17th century sash windows started to become more attractive. They started with coloured glazing bars or mullions. These were very expensive at the time, but as glass production improved and cost-effective, they became a feature of many of the period homes.

In the 19th century, it became possible to create large, sturdy glasses that didn't require supporting bars. This allowed the frame's size to increase further, which allowed for a wider view from the window. This was a significant innovation.

The introduction of the double-hung sliding sash was another important improvement that occurred in the I920s and the beginning of the I930s. This allowed both the upper and lower sash to be opened simultaneously and also improved the ventilation of buildings.

Oak was used for older examples and more prestigious buildings. A parting bead is used to separate the two sashes. It is important that this is maintained in order to avoid rattles and draughts. It is also essential that the idler and sash pulley wheels are in good condition as these assist in operating the window.

2. Energy efficiency

Sash windows replaced hinged cases as larger and clearer sheets became available. They were glazed with plate glass set in timber frames with rebates and secured 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 an increase in demand for ironmongery. The basic fittings included brass pulleys (and later cast-iron) weights as well as sash stoppers, shutter hinges and handles as well as various fasteners used to fix the sashes. These were often decorated with motifs, inscriptions and designs that were engraved to identify the maker.

Sash windows are energy-efficient with regular maintenance. Without this maintenance, they can become drafty. Draughts can also be caused by the deterioration of putty and paint. This can be fixed by making use of wood-to-timber repair tools that are proprietary.

The replacement window industry relies heavily on the notion that older windows are beyond repair and cannot be maintained economically. However windows can be easily maintained with a little attention. These repairs can be costly and cause a lot of disruption in the home. To avoid this, many homeowners choose to replace their windows with PVC-u windows from one the many "one-stop shop" installation companies. They can replace all windows in a house in a single day, saving time and avoiding the need for different tradesmen to coordinate. These windows can be fitted with 'energy-saving double glazing to get more energy efficient ratings than a traditional sash window. However these double-glazed units are unable to replicate the section and proportions of historic timber sashes.

3. Security

Traditional windows can be made secure without compromising their style. There are many types of ironmongery that can be fitted with sash chains, mortice bolts, and sash locks. They can be fitted in such a way that the window is able to be opened for ventilation and cleaning. These are typically not noticeable, since they are designed to fit the sash window. They can be utilized in conjunction with traditional sash-window catchers that must be replaced by more robust versions (such as those incorporating double screws) or spring levers to decrease the chance of them being hammered out.

Sash-window frames were typically made from slow-growing deal or, in the more luxurious homes they were made from oak. Where glazing bars have survived they should be preserved, and if it is it is possible, the timber of the cill should be replaced by the same wood. PVC-u companies often provide a one-stop shop installation service, removing and replacing windows on an entire home in a single day without the need to engage other tradespeople or co-ordinate various visits from different suppliers.

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 had been modified so that more light could be let into the rooms. Larger glass panes were also made. The result was a more light appearance and windows that were more elegant.

Sash windows were introduced that required a brand new type of ironmongery. Early pulleys were made from wood, whereas later Victorian ones could be made of brass or a combination of lead and wood and there were many kinds of shutter hinges and knobs. The ironmongery pieces need to be kept clean and preserved in order to appreciate their exquisite design.

Timber windows require regular maintenance to ensure they remain in good shape. Inattention to maintenance can lead to:

Sashes that do not slide smoothly.

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

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

Steel casement windows gained popularity in the I920s and I930s because they were sturdy and slim, cheap and matched the trend towards healthy living. Studies have shown that softwood sash windows are just as effective as PVC-u windows and can even be more attractive.

The window replacement industry was able to convince homeowners that their old windows were decayed and drafty. They were also beyond the budget for repair. The reality is that many old windows made of wood are in good shape and with minor repairs can easily be serviceable for many years to be.

5. Maintenance

A traditional sash window needs regular maintenance and inspection. Failure to do this can result in sash cords breaking, excessive wear on the glazing bars, and the deterioration of putty and paint. The removal of the sashes may also cause structural movement within the frame which causes the sash to be misaligned and in a position that it is not able to close properly. The sash can also be stuck in an open position, allowing water and draughts into the building.

Moisture penetration is a frequent cause of damage to timber windows. This can be prevented with thorough painting, regular repairs and the elimination of the cause of dampness. Wet rot is easily identified by the wavy appearance of the existing paint which can be stripped to reveal soft, rotting wood. The rotten timber sections must be removed with care and the affected part should be scarfed together or pieced together with replacements of the exact type as the remaining timber. This method of repair maximises the amount of original fabric left, and is one of the least invasive methods of treating timber-to-timber decay.

The use of a wood consolidant made from resin is an alternative to the traditional method of staining and sanding. The product is brushed on the surface of the wood to protect it and strengthen it. It is particularly beneficial for the treatment of pulleys and sash cords which can help stop breakage.

It is essential that any historic ironmongery like sash stays and latches are kept and restored instead of replaced. These items are difficult to replace without harming the the original design. It is also recommended that the use of modern aluminium fittings such as sash lifts and chain stays is avoided if at all feasible as they could cause corrosion and deterioration to frames and sashes made from timber.
