How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge have sash windows with traditional designs and homeowners are proud of the way they look. However, sash windows may become stuck and difficult to open or close. This is often due to moisture, which can cause the timber to swell.

Box sash windows were historically operated by chains, cotton cords and weights made of lead. Modern sash windows have hidden springs to address this problem.

1. Aesthetics

Contrary to PVC-u windows which are made according to the modular imperial size, timber sash windows can be restored to their original dimensions. This allows the restoration of timber sash windows to meet current energy requirements and conform to conservation regulations for areas. It also offers windows that are superior to the uPVC alternatives.

Sliding windows with sash were initially only found in large buildings or public buildings, however this changed when production was less expensive and craftsmen were able to create larger frames using more glass. In the late 18th century Sash windows were the most popular design of wood in the majority of British homes. Sash windows were simple to operate and let light in rooms without the need for curtains.

The first windows were made of plain glass, but in the 17th century, sash windows were becoming more attractive with coloured glass bars and moulded mullions. They were expensive at first, but when glass production became less expensive and more efficient, they were commonplace in many homes of the period.

In the 19th century it was possible to manufacture large, strong glass that did not need supporting bars. This allowed the frame size to be increased even more, which in turn gave a better view out of the window. This was a very important innovation.

Another important improvement was the introduction of the double-hung sliding windows at the end of 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.

The most common type of sash is constructed of slow-growing deal (pine) but oak was also used in more expensive buildings as well as in some earlier examples. It is important to maintain the parting bead which separates the sashes. This will help prevent rattles and draughts. It is also important that sash pulleys and idler wheels are in good working order as they help to operate the window.

2. Energy efficiency

Sash windows were replaced by hinged casements as larger and clearer sheets became available. Glass plates were set in frames of timber that were rebated, then pinned with glazing sprigs and putty was sprayed on the frame's sides for watertightness. This kind of glazing gradually replaced the leaded light bulbs.

Sashes were introduced, which led to increased demand for ironmongery. The most common fittings included brass pulleys (and later cast-iron) weights and stoppers for sashes shutter hinges and handles, and various fasteners used to secure the sashes. They were often decorated with motifs, inscriptions and designs that were engraved to identify the maker.

Sash windows are energy efficient when they are maintained regularly. But, if you don't maintain them, they may become drafty and let in cold air. Putty and paint can cause draughts too. This can be fixed by using proprietary wood-to-timber repair products.

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 easily be maintained with a bit of attention. However, repairs to these windows can be expensive and involve considerable disruption to the home. To prevent this, many homeowners choose to replace their windows with PVC-u windows from one the large 'one stop shop' installation companies. They can replace and remove all the windows in a house within a single day, eliminating the need to coordinate different tradesmen, making the whole process much quicker. They can also be supplied with 'energy saving' double-glazing to get more energy efficient ratings than traditional windows with sash. These double-glazed windows aren't able to replicate the proportions or section of the sashes made of timber from the past.


3. Security

It is possible to secure windows that are traditional without compromising their style. Ironmongery like sash chain, mortice bolts and sash lock could be installed. double glazing repair cambridge can be fitted in a way so that the window can be opened for ventilation and cleaning. They are usually not noticeable since they are designed to complement sash windows. They can be used with traditional sash window catches. These should be replaced by more robust models, such as ones that have double screws or sprung levers in order to reduce the possibility of being struck by hammers.

Sash-window frames were typically constructed from slow grown deal or, in the more prestigious houses they were made from oak. Where glazing bars have survived they should be kept and if it is possible, the timber of the cill should be replaced with matching wood. PVC-u companies typically offer a one stop shop installation service, which includes removing and replacing windows on an entire home in a single day without the need to involve other tradespeople, or coordinate visits from different suppliers.

4. Ventilation

Sash windows were introduced in the 17th century and allowed for a huge amount of light into buildings. In the 18th century, they had been adapted so that even more light could be let into rooms. Larger glass panes were also made. The result was a more light appearance and windows that were more elegant.

Sash windows were introduced and required a new type of ironmongery. Early pulleys were made from wood. Later Victorian ones were made of brass or a mixture of wood and leaded. There were also a variety of types of knobs and shutter hinges. The ironmongery components should be maintained and cleaned to ensure that the exquisite quality of their design can be appreciated.

To ensure they remain in good condition, timber windows require regular maintenance. Lack of regular attention may lead to:

Sashes that no longer slide easily.

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

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

In the I920s and I930s steel casement windows gained popularity due to their strength slim and affordable, and complemented the vogue for healthy living. However, research has shown that traditional softwood sash windows are just as efficient thermally as PVC-u double-glazed windows, and can be more attractive than the sleek lines of contemporary casement windows.

The replacement window industry has done a lot to persuade house owners that their old windows are rotten, draughty and beyond repair. However, many old timber windows are in good shape and with minor repairs can easily be maintained for years to come.

5. Maintenance

The traditional sash windows need regular maintenance and inspection. Inability to maintain it properly can lead to the sash cords breaking, a lot of wear on the glazing bars and the deterioration of putty and paint. The removal of sashes could also result in structural movements within the frame, causing the sash not to close properly. It is also possible for the sash to be stuck or fixed in an open position and this can let water and draughts in the structure.

Moisture penetration is a frequent cause of damage to timber windows. This can be prevented by regular maintenance, thorough painting and removing the source of dampness. Wet rot is easily identified by the wavy appearance of the paint that can be stripped away to reveal soft, rotting wood. Any rotten sections of timber must be removed and the affected part carefully cut or pieced with replacements made of the same type of wood as those remaining. This method of repair maximises the amount of original fabric retained and is one of the least invasive methods of treating timber-to-timber decay.

The use of a resin-based wood consolidant is a different option 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 useful for the treatment of sash cords and pulleys which help prevent breakage.

It is crucial to restore and not replace any old ironmongery such as sash latches and stays. It can be difficult to replace these items without altering their original design. It is also recommended that the use of modern aluminium fittings such as sash lifts and chain stays should be avoided if possible since they can cause corrosion and deterioration to frames and sashes made from timber.
