How to Restore timber double glazed windows cambridge Sash Windows in Cambridge

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

Box sash windows were historically operated with chains or cotton cords as well as lead weights. Modern windows with sash springs are concealed to eliminate this issue.

1. Aesthetics

Timber sash windows, in contrast to PVC-u windows which are manufactured in imperial sizes and are modular, can be reconstructed to original dimensions. This lets the restoration meet modern day energy requirements while ensuring compliance with conservation area regulations. It also comes with an option that is superior to the uPVC options.

Sliding sash windows were initially only used in large buildings or public buildings, however the production process became cheaper and craftsmen could create larger frames using more glass. At the close of the 18th century, sash windows were the most popular wooden design in British homes. Since 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, but in the 17th century the sash windows began to become more attractive. They began with colored glazing bars or mullions. They were costly at the beginning but as glass production became less expensive and more efficient, they were commonplace in many period houses.

In the 19th century, it became possible to produce large, strong glasses that did not require support bars. This allowed the frame to be made larger and, in turn, gave an improved view. This was a very important innovation.

Another important improvement was the introduction of the double-hung sliding windows at the end of the I920s and beginning of the I930s. The double-hung sliding sash was a important improvement that was made at the end of the I920s, and at the beginning of the I930s.

Oak was used for older examples and more prestigious buildings. A parting bead is used to separate the two sashes and it is important that this is maintained to prevent rattles and drafts. The idler wheels, sash pulleys and sash rollers are also crucial to the functioning of the Window And Door Repair Near Me.

2. Energy efficiency

As clearer and larger sheets of glass were made available, sash windows started replacing hinged casements. They were made of plate glass, set in timber frames with rebates and pinned in place using glazing sprigs, and then putty on both sides to ensure they were watertight. This type of glazing gradually replaced the use of leaded lights.

Sashes were introduced, which resulted in 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 a variety of fasteners used to fix the sashes. These were often decorated with motifs, inscriptions and designs that were engraved to identify the maker.

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

The market for replacement windows rests on the belief that traditional windows are rotten and beyond repair, while they can be maintained with a bit of care. Repairs can be costly and cause a lot of disruption in the home. Many homeowners opt to replace their windows with PVC-u from a large "one-stop shop" company for installation. They can take down and replace all windows in a home in just one day, avoiding the need to coordinate different tradesmen and making the entire process much faster. They can also be fitted with 'energy saving' double-glazing to achieve more energy efficient ratings than are possible with traditional windows made of sash. However, these double-glazed units cannot replicate the section and proportions of the sashes made of timber from the past.

3. Security

Traditional windows can be secured without compromising their appearance. Ironmongery such as mortice bolts, sash chain, and sash lock can be used. These can be installed in such a way that the window doctor is able to be opened for ventilation and cleaning. They are usually unobtrusive as they are designed to be used in conjunction with sash windows. They can be used in conjunction with traditional sash-window doctor cambridge catchers and should be replaced with more robust models (such ones with double screws) or spring levers to decrease the possibility of them being hammered out.

Sash-window frames are usually made of oak or slow-grown deal. If the glazing bars remain intact and are not damaged, they should be left. Where feasible, the cills made of timber should be replaced with timber that is compatible with. Many PVC-U companies offer a one-stop shop installation service. They can take down and replace windows on a complete home in one day, without involving other tradespeople.

4. Ventilation

Sash windows were first introduced in the 17th century and allowed for a huge amount of light to be absorbed into buildings. At the end of the 18th century, they had been modified so that more light could be let into rooms. Larger glass panes were also created. The result was a more light appearance and windows with more elegance.

The introduction of sash windows also required the creation of a new line of ironmongery. Early pulleys were made from wood. Later Victorian ones were made of brass or a mix of wood and lead. There were also a variety of kinds of knobs and shutter hinges. Ironmongery elements must be retained and cleaned down so that the quality of their design can be appreciated.

To keep them in good condition, timber windows must be maintained. Inattention to maintenance routinely could result in:

Sashes that do not move easily.

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

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

In the I920s and I930s steel casement windows gained popularity due to their durability slim and inexpensive and also matched the fashion for healthy living. However, research has proven that traditional softwood sash windows can be just as thermally efficient as PVC-u double-glazed windows, and are more attractive than the sleek lines of modern casement windows.

The replacement window industry has made a significant effort to persuade house owners that their old windows are dirty, noisy and beyond repair. Many old windows made of timber can be repaired and utilized for a longer period with minor repairs to upvc doors.

5. Maintenance

Traditional sash windows require regular maintenance and inspection. Failure to do this can result in broken sash cords, excessive wear on the glazing bars and degradation of the paint and putty. The removal of sashes could also result in structural shifts within the frame, which causes the sash to be misaligned and not closing properly. It is also possible for the sash be snagged or slammed into an open position and let water and draughts into the property.

Moisture penetration is the most common cause of damage to timber windows. This can be prevented by thorough painting, periodic repairs and the elimination of the cause of dampness. Wet rot can be identified due to the wavy appearance of the existing paint which can be removed to reveal soft, rotting timber. Any rotten timber sections must be removed and the affected area carefully wrapped or pieced back using replacements made of the same type of wood as the ones remaining. This method of repair maximises the amount of fabric that is left and is among the least invasive ways of treating decay of timber to timber.

The use of a resin-based wood consolidant is an alternative to the traditional method of staining and sanding. The product is brushed on to the surface of the timber to stabilise and shield it from further damage. It is particularly beneficial for the treatment of sash cords and pulleys which help stop breakage.

It is important to restore and not replace any old ironmongery such as the sash latches and stays. They can be extremely difficult to replace without compromising the quality of the original design. It is also recommended that the use of modern aluminium fittings like 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.
