How to Restore Timber Sash Windows in Front Doors Cambridge (Http://Leewhan.Com/Bbs/Board.Php?Bo_Table=Free&Wr_Id=1653667)

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 usually due to moisture that can cause the timber to expand.

Traditionally, window boxes utilised chains, cotton cords or lead weights to operate. Modern sash windows have hidden springs to solve this issue.

1. Aesthetics

Timber sash windows, unlike PVC-u windows which are manufactured in imperial sizes that are modular, are able to be restored to their original dimensions. This allows the restoration to meet modern day energy requirements while complying with conservation areas regulations. It also gives windows that have a superior appearance than upvc windows cambridge alternatives.

Sliding sash windows were originally only used in large structures or public buildings, though the production process was less expensive and craftsmen were able to produce larger frames with more glass. By the end of the 18th century, sash windows were the most sought-after wooden style in British homes. Because they were simple to open, sash windows let light into rooms without curtains.

Early windows were simple glass but by the 17th century, sash windows began to become more decorative, with coloured glazing bars and moulded mullions. They were costly initially, but as glass production became cheaper and more efficient, they became a common feature in many historic homes.

In the 19th century, it was possible to make large, strong glass that did not need supporting bars. This allowed the frame to be made bigger which, in turn, provided the viewer a better view. This was an important innovation.

Another significant improvement was the introduction of the double glazing windows cambridge-hung sliding window at the end of I920s and the beginning of the I930s. This allowed both the upper and lower sash to be opened simultaneously, and allowed for better ventilation to buildings.

Oak was used for older examples and for more prestigious buildings. A parting bead is used to separate the two sashes. It is important that this is well maintained to prevent rattles and draughts. The sash pulleys, idler wheels and sash rollers are vital to the operation of the window.

2. Energy efficiency

As larger and clearer glass sheets became available, sash window began replacing hinged casements. Plate glass was placed in frames of timber that were rebated, then pinned with glazing sprigs and putty was then sprayed onto the frame's two sides to ensure watertightness. This kind of glazing gradually superseded leaded lights.

Sashes were introduced, which resulted in an increase in 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.

With regular maintenance, sash windows are extremely energy efficient. However, if they are not maintained, they may become drafty and let in cold air. Draughts can also be caused by the breakdown of putty and paint. This can be corrected using wood-to-timber repair products that are specifically designed for this purpose.

The replacement window restoration cambridge industry relies heavily on the perception that old windows are damaged beyond repair and are not able to be maintained economically. However they can be maintained with a bit of attention. However, repairs to these windows can be costly and cause considerable disruption to the home. To prevent this homeowners often prefer to replace their windows with PVC-u windows from one of the large "one stop shop" installation companies. These can remove and replace all the windows in a home in a single day, eliminating the need to co-ordinate different tradesmen, making the whole process much quicker. They are also available with energy-saving double-glazing to achieve higher energy efficiency ratings than are possible with traditional windows made of sash. These double-glazed windows aren't capable of replicating the proportions and sections of historic timber sashes.

3. Security

Traditional windows can be made secure without compromising their appearance. Ironmongery, such as mortice bolts, sash chain and sash locks can be put in place. They can be positioned in a way so that the window is able to be opened to allow ventilation and cleaning. These are typically unobtrusive, as they are designed to fit the sash window. They can be utilized in conjunction with traditional sash window catches that should be replaced with more robust versions (such ones that have double screws) or spring levers to decrease the possibility of them being hammered out.

Sash-window frames were typically constructed from slow-growing deal or, in more prestigious houses made of oak. When glazing bars have survived they should be kept, and where it is possible, the timber of the cill should be replaced by the same wood. Many PVC-u firms offer a one-stop shop installation service. They can remove and replace windows on an entire home in a single day, without the need to involve other tradespeople.

4. Ventilation

Sash windows were introduced in the 17th Century and allowed for a huge amount of light to be absorbed into buildings. By the end of the 18th century they were altered to allow even more light into rooms, and larger glass panes began to be produced. The result was a much lighter appearance and windows with a greater level of elegance than they had before.

Sash windows were introduced that required a brand new range ironmongery. Early pulleys were made out of wood. Later Victorian ones were made of brass or a combination of leaded and wood. There were also a variety of types of shutter hinges and knobs. These ironmongery elements should always be maintained and cleaned so that the fine quality of their design can be appreciated.

To keep them in good shape, timber windows must be maintained. Inattention to maintenance could lead to:

Sashes that do not slide easily.

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

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

Steel casement windows gained popularity in the I920s and I930s because they were strong and slim, and also because they were cheap and matched the trend of healthy living. Research has shown that softwood sash window are just as efficient as PVC-u windows, and may even be more attractive.

The replacement window industry has made a significant effort to persuade house owners that their traditional windows are old, dirty, and beyond repair. The reality is that many old windows made of wood are in good condition and, with minor repairs, could easily be serviceable for many years to come.

5. Maintenance

The traditional sash windows need regular maintenance and inspection. Inability to keep up with this can lead to sash cords breaking, front doors cambridge 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, which can cause the sash to not close correctly. The sash can also be stuck in an open position, allowing water and draughts to enter the property.

Damage to windows made of timber is often caused by moisture entry. This can be avoided by careful painting, regular repairs, and removing the source of dampness. The paint can be removed to reveal the soft, rotting wood. Any timber that is rotting should be cut off and the affected area should be carefully scarfed or pieced in using replacements made from the same type of wood as those remaining. This method of repair maximizes the amount of fabric that is left and is among the least invasive methods of treating decay caused by timber.

The use of a resin-based wood consolidant is a different option to traditional sanding and staining. This is brushed onto the surface of the timber to stabilize it and protect it from further damage. It is particularly useful for the treatment of pulley cords and sash which can help prevent breakage.

It is crucial to restore and not replace any historic ironmongery, like stay latches and sash latches. It can be difficult to replace these items without compromising their original design. It is also recommended that modern aluminium fittings like sashlifts, as well as chainstays, be avoided as they can cause deterioration and corrosion of timber frames and sashes.
