How to Restore Timber Sash Windows in Cambridge
Many homes in Cambridge have traditional sash windows and homeowners are proud of the way they look. However, sash windows may get stuck and be difficult to open or close. This is often due to moisture which can cause the timber to swell.
Traditionally, window doctor boxes utilised chains or cotton cords and lead weights to operate. Modern sash windows have hidden springs to overcome this problem.
1. Aesthetics
Timber sash windows, unlike PVC-u windows which are manufactured in imperial sizes that are modular, are able to be restored to original dimensions. This allows for the restoration of timber sash windows in order to comply with current energy standards and conform to conservation regulations for areas.

Sliding windows with sash were initially intended for large structures or public buildings. However this changed as production became less expensive and craftsmen could produce larger frames with greater glass. In the 18th century, Sash windows were the most popular design of wood in the majority of British homes. As they were easy to open, sash windows let light into rooms without curtains.
Early windows were simple glass, but by the 17th century sash windows were becoming more decorative with coloured glazing bars and moulded mullions. These were very expensive at the time, but as glass production became more efficient and cost-effective, they were a common feature in many period houses.
In the 19th century, it was possible to make large, sturdy glasses that did not require support bars. This allowed the frame to be enlarged which, in turn, provided the viewer a better view. This was an important innovation.
Another significant improvement was the introduction of the double-hung sliding windows at the end of 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 beginning of the I930s.
Oak was used for older and more luxurious buildings. A parting bead separates the two sashes and it is important that this is well maintained to prevent rattles and draughts. It is also essential that sash pulleys and idler wheels are in good condition as these aid in operating the window.
2. Energy efficiency
As clearer and larger sheets of glass became available, sash window began to replace hinged casements. Plate glass was set into frames of timber that were rebated, then which were pinned with glazing sprigs, and putty was applied to the frame's sides to ensure watertightness. This form of glass gradually replaced 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 engraved patterns that identified the maker.
Sash windows are energy efficient if they are maintained regularly. Without this maintenance they could become noisy. Draughts can also result from the degeneration of paint and putty. This can be fixed by using wood-to-timber repair products that are specifically designed for this purpose.
The replacement window industry relies on the perception that old windows are damaged and beyond economical repair, but they are able to be maintained with a bit of care. 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 of the many 'one stop shop' installation companies. They can replace and remove all windows in an entire house in a single day, avoiding the need to coordinate different tradesmen and making the entire process much faster. They can also be supplied with energy-saving double-glazing, which can achieve greater energy efficiency than traditional windows made of sash. These double-glazed units are not capable of replicating the proportions or section of sashes from old timber.
3. Security
It is possible to secure windows that are traditional without compromising their style. Many types of ironmongery can be fitted with sash chains, mortice bolts and locks for sash. They can be fitted in a way that the window is able to be opened to allow ventilation or cleaning. They are generally not noticeable, since they are designed to match the sash window. They can be used with traditional sash window catches. These are best replaced with more robust versions, such as those that incorporate double screws or sprung levers to decrease the risk of being struck by hammers.
Sash-window frames were traditionally made from slow-growing deal or, in more prestigious houses made of oak. Where glazing bars have survived they should be preserved, and where it is possible, the timber of the cill should be replaced with the same wood. PVC-u companies often offer 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 co-ordinate various visits from a number of different suppliers.
4. Ventilation
When sash windows were first introduced in the 17th century, they allowed a large amount of light into buildings. At the end of the 18th century, they were modified to let even more light into rooms, and bigger glazing panes started to be produced. The result was a lighter look and windows with more elegance.
The introduction of sash windows also necessitated the creation of a new line of ironmongery. The first pulleys were made of wood, whereas later Victorian ones were made of brass or a mixture of lead and wood, and there were many kinds of shutter hinges and knobs. Ironmongery elements must be maintained and cleaned so that the fine quality of their design can be appreciated.
Timber windows require careful maintenance to ensure they remain in good order. Lack of attention to them regularly could lead to:
Sashes that do not slide easily.
holes in the frame allow water causing damage and decay.
Water can get into the putty and cause decay to the frame or cause cill.
Steel casement windows gained popularity in the I920s & I930s because they were sturdy and slim, cost-effective and matched the trend towards 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 lot to persuade house owners that their old windows are dirty, noisy and beyond repair. Many old windows made of timber can be repaired and used for a long time with minor repairs.
5. Maintenance
A traditional sash window needs regular maintenance and inspection. Inability to maintain it properly could result in sash cords breaking, excessive wear on the glazing bars and the deterioration of putty and paint. The removal of sashes could also cause structural movement in the frame, causing the sash to not close correctly. The sash may also become 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 avoided by regular repairs by thorough painting and eliminating the source of dampness. Wet rot is easily identified due to the wavy appearance of the existing paint which can be stripped away to reveal soft, rotting wood. The sections that are rotting must be removed with care, and the affected area should be snared together or glued together by using replacements of the same kind as the timber that remains. This method of repair increases the amount original fabric and is among the least invasive ways to treat wood-to-timber rot.
A wood condenser that is based on resin is a viable alternative to traditional process of sanding or staining. The product is brushed on the surface of the wood to protect it and stabilize it. It is particularly useful for the treatment of pulleys and sash cords where it can help to stop breakage.
It is crucial to restore and not replace any historic ironmongery, like sash latches and stays. It is difficult to replace these items without altering their original design. It is recommended that the use of modern aluminum fittings such as chain stays and sash lifts is avoided if at all feasible as they could cause corrosion and damage to timber frames and sashes.
