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

Box sash windows were historically operated by chains or cotton cords as well as lead weights. Modern sash windows come with hidden springs to overcome this problem.

1. Aesthetics

Timber sash windows, unlike PVC-u windows that are made in imperial sizes and are modular, are able to be restored to their original size. This allows the restoration to be in line with modern energy requirements while ensuring compliance with conservation areas regulations. It also provides a window that is far superior to the uPVC options.

Sliding windows with sash were initially only used for large buildings or public buildings. However the production became cheaper and artisans could create larger frames using more glass. By the late 18th century Sash windows were the most popular wooden windows and doors cambridge design in most British properties. Sash windows were easy to operate and allowed light to enter rooms without the need for curtains.

Early windows were plain glass, but in the 17th century sash windows began to become more attractive with coloured glass bars and moulded mullions. These were very expensive at the time but as glass production became more efficient and cheaper they were a common feature in numerous period houses.

In the 19th century it was possible to create large, sturdy glass that didn't require support bars. This allowed the frame's size to increase further, which gave a better view out of the window. This was a significant advancement.

The introduction of the double-hung sliding sash was a significant improvement that came about towards the end of the I920s and the beginning of the I930s. This allowed both the lower and upper sash to be opened simultaneously, and gave improved ventilation to buildings.

The most common type of sash is constructed from slow-growing deal (pine) but oak was utilized in more luxurious buildings and in some earlier examples. A split bead divides the two sashes. It is important that this is maintained to prevent rattles and draughts. The sash pulleys, idler wheels and sash rollers also are vital to the functioning of the window.

2. Energy efficiency

Sash windows replaced hinged cases as larger and clearer sheets became available. They were glazed with plate glass placed within timber frames with rebates and pinned in place using glazing sprigs, with putty on both sides to make them watertight. This form of glazing gradually replaced Leaded glass window repair lights.

Sashes were introduced, which led to an increase in demand for ironmongery. The most basic fittings were brass pulleys (and later cast-iron) weights and stoppers for sashes shutter hinges and handles as well as a variety of fasteners used to secure the sashes. They were often decorated with patterns, inscriptions and engravings to identify the maker.

Sash windows can be extremely energy-efficient with regular maintenance. If they are not maintained, they can become noisy. Draughts can also be caused by the deterioration of putty and paint. You can fix this problem by using wood-to-timber products.

The market for replacement windows is based heavily on the notion that older windows are beyond repair and cannot be maintained economically. However they can be maintained with a little attention. However, these repairs can be expensive and involve considerable disruption to the home. To prevent this homeowners, many opt for a complete replacement with PVC-u windows from one of the largest "one-stop shop" installation companies. They can take down and replace all the windows in a home in just one day, eliminating the need to coordinate multiple tradesmen and making the whole process much quicker. They can also be fitted with 'energy-saving' double-glazing, which can achieve greater energy efficiency than traditional windows made of sash. Double-glazed windows aren't able to replicate the proportions and section of sashes from old timber.

3. Security

It is possible to secure traditional windows without compromising on their aesthetics. A variety of ironmongery types can be fitted with sash chains, mortice bolts and locks for sash. They can be fitted in a way so that the window is able to be opened for ventilation and cleaning. They are usually discrete since they are made to complement sash windows. They can be used with traditional sash window catches. They should be replaced with more robust models, such as ones that have double screws or sprung levers, to minimize the possibility of being hammered.

Sash-window frames are traditionally made of oak or slow-grown deal. Where glazing bars have survived they should be kept, and, if possible, the timber of the cill should be replaced with the same wood. PVC-u companies typically provide a one-stop shop installation service, which includes removing and replacing windows on a complete home in a single day without the need to involve other tradespeople or co-ordinate various visits from a number of different suppliers.

4. Ventilation

Sash windows were introduced in the 17th century and allowed for a huge amount of light to enter buildings. At the end of the 18th century they were modified to let more light into rooms and larger glass panes began to be manufactured. The result was a much lighter appearance and windows with a higher level of elegance than they had before.

The introduction of sash windows also demanded the creation of a new line of ironmongery. The first pulleys were made of wood, while later Victorian ones could be made from brass or a combination of lead and wood, and there were various types of shutter hinges and knobs. Ironmongery elements must be retained and cleaned down so that the fine quality of their design can be appreciated.

Timber windows require regular maintenance to keep them in good condition. Lack of attention to them regularly can result in:

Sashes that do not slide easily.

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

break down of putty, allowing water penetration that can lead to decay in the frame and cill.

In the I920s and I930s steel casement windows grew in popularity due to their strength slim and affordable and were in line with the trend for healthy living. Research has shown that softwood sash windows are just as efficient as PVC-u windows, and may even be more attractive.

The window replacement industry has done a lot to persuade house owners that their windows are rotten, draughty and beyond economic repair. Many old windows made of timber can be repaired and utilized for a longer period with minor repairs.

5. Maintenance

A traditional sash window repair needs 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 wearing out excessively. It could also cause paint and putty to deteriorate. The removal of sashes can also result in structural shifts within the frame, which causes the sash to be misaligned and in a position that it is not able to close properly. The sash could also get stuck in its open position, allowing the water and drafts to enter the building.

Damage to timber windows is often caused by water penetration. This can be prevented with thorough painting, regular repairs and the elimination of the source of dampness. Wet rot can be identified due to the wavy appearance of the existing paint which can be removed to reveal soft, rotting wood. Any rotten timber sections must be removed and the affected area carefully cut or pieced with replacements made from the same kind of timber as the ones that remain. This repair method increases the amount original fabric and is one of most minimally invasive methods of treating the rot that occurs between timber and timber.

A wood condenser made of resin is an alternative to the 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 useful to treat pulley cords and sash which can stop breakage.

It is important that any ironmongery from the past such as sash stays and latches be kept and restored rather than replaced. These items can be very difficult to replace without harming the the original design. It is also recommended that the use of modern aluminium fittings like chain stays and sash lifts should be avoided if possible since they can cause corrosion and deterioration to frames and sashes made of timber.
