How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge have traditional sash windows and homeowners are proud of how they look. However, sash windows can get stuck and be difficult to open or close. This is usually due to moisture which can cause the wood to expand.

Traditionally, windows made of box sash used chains or cotton cord and weights made of lead to operate. Modern window springs for sash windows are concealed to eliminate this issue.

1. Aesthetics

In contrast to PVC-u windows, which are manufactured to modular imperial sizes the timber sash windows are able to be restored to their original dimensions. This allows the restoration of timber sash windows to comply with current energy standards and conform to conservation area regulations. It also gives windows with a superior appearance than the uPVC alternatives.

Sliding sash window maintenance frames were initially intended for large structures or public buildings. However this changed as production became more affordable and artisans could create larger frames using more glass. By the end of the 18th century, sash windows were the most popular wooden style 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 clear glass, but in the 17th century the sash windows began to become more ornamental. They were initially made of colored glazing bars or mullions. They were costly initially, but as glass production became cheaper and more efficient, they were an integral feature in many historic homes.

In the 19th century it was possible to create large, sturdy glass that did not require supporting bars. This allowed the frame size to be increased even further and this in turn meant more of a view from the window. This was an important innovation.

The introduction of the double-hung sliding sash is another significant improvement that came about in the I920s and beginning of the I930s. This allowed both the upper and lower sash to be opened at the same time and gave improved ventilation to a building.

The most common type of sash is constructed from slow-growing deal (pine) but oak was also used in more expensive buildings as well as in some earlier examples. A parting bead is used to separate the two sashes. It is important that this is well maintained to prevent rattles and drafts. It is also crucial that the idler and sash pulley wheels are kept in good condition as these aid in operating the window mechnism repair.

2. Energy efficiency

Sash windows replaced hinged cases as clearer and larger sheets were made available. Plate glass was placed in frames of timber that were rebated, then secured with glazing sprigs and putty was applied to the frame's sides to ensure watertightness. This type of glass gradually replaced the leaded light bulbs.

Sashes were introduced, which resulted in an increase in demand for ironmongery. The most common fittings included brass pulleys (and later cast-iron) weights, sash stoppers, shutter hinges and handles as well as various fasteners used to fix the sashes. These were often decorated in designs, inscriptions, and patterns engraved to identify the maker.

With regular maintenance, sash windows can be extremely energy efficient. But, if you don't maintain them, they can become draughty and let in cold air. Draughts can also result from the degeneration of paint and putty. This can be fixed by making use of wood-to-timber repair tools that are proprietary.

The replacement window industry relies heavily on the perception that older windows are beyond repair and cannot be maintained economically. However they can be maintained with a bit of attention. Repairs can be expensive and cause lots of disruption to the home. To prevent this, many homeowners opt for a complete replacement with PVC-u windows made by one of the large "one stop shop" installation companies. They can replace all windows in a home in a single day, saving time and eliminating the need for various tradesmen to coordinate. They are also available with 'energy saving' double-glazing to get more energy efficient ratings than traditional windows made of sash. These double-glazed units are not able to replicate the proportions or section of the sashes made of timber from the past.

3. Security

Traditional windows can be secured without compromising their style. Ironmongery such as sash chain, mortice bolts and sash locks can be put in place. These can be put in place to ensure that the window is capable of being opened to allow ventilation or for cleaning. These are typically not noticeable, since they are designed to match the sash window. They can be used alongside traditional sash-window catches, which should be replaced with more robust models (such ones with double glazing repairs cambridge 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 the more elegant homes they were made from oak. If the glazing bars are still intact and in good condition, they should be kept. If feasible, the cills made of timber should be replaced with wood that matches. PVC-u companies typically provide a one-stop shop installation service that can remove and replacing windows on a complete home in a single day without the need to engage other tradespeople, or coordinate visits from different suppliers.

4. Ventilation

When sash windows were first introduced in the 17th century they allowed a significant amount of light into buildings. At the end of the 18th century, they were modified to let more light into rooms, and bigger glazing panes started to be 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 of wood, whereas later Victorian ones were made from brass or a mixture of lead and wood and there were many kinds of shutter hinges and knobs. The ironmongery components should be kept 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 don't slide easily.

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

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

In the I920s and I930s, steel aluminium casement windows cambridge windows gained popularity due to their durability, slim and cheap and were in line with the trend for healthy living. However, research has revealed that traditional softwood sash windows are just as efficient in thermal efficiency as double-glazed windows made of PVC-u, and can be more attractive than the modern sleek design of casement windows.

The industry of replacement windows has done a lot to persuade house owners that their old windows are dirty, noisy and beyond economic repair. The reality is that many older timber windows are in good shape and with minor repairs can easily be repaired for many years to be.

5. Maintenance

The traditional sash windows require regular maintenance and inspection. If you fail to maintain your sash window, it can cause the sash cords breaking and the glazing bars wearing out excessively. It can also cause the paint and putty to degrade. The removal of sashes can also result in structural shifts within the frame, which causes the sash to become misaligned and in a position that it is not able to close properly. The sash could also get stuck in its open position, which allows the water and drafts to enter the property.

Damage to windows made of timber is often caused by moisture entry. This can be prevented by regular maintenance, thorough painting and removing the cause of dampness. The paint can be removed to reveal the soft, decaying wood. The sections of timber that are rotten should be carefully removed and the affected part should be scarfed together or pieced together with replacements of the exact kind as the timber that remains. This method of repair maximizes the amount of fabric that was originally used and is among the most non-invasive methods to treat timber-to-timber rot.

A resin-based wood condenser is an alternative to the traditional staining or sanding. This is brushed on the surface of the wood to protect it and strengthen it. It is especially useful for the treatment of pulley cords and sash, where it can prevent breakage.

It is crucial to restore and not replace any historic ironmongery, like sash latches and stays. They can be extremely difficult to replace without compromising the the original design. It is also advised that fittings made of aluminum like sashlifts and chainstays, should be avoided since they can cause corrosion and deterioration of timber frames and sashes.
