How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge feature traditional sash window and the homeowners are proud of their appearance. However, sash windows may become stuck and difficult to open or close. This is usually due moisture which can cause the wood to expand.

Traditionally, window boxes used chains or cotton cords and weights made of lead to operate. Modern sash windows have hidden springs to solve this problem.

1. Aesthetics

Timber sash windows, unlike PVC-u windows that are made in imperial sizes, which are modular, can be restored to their original dimensions. This permits the re-installation of timber sash windows to meet the current energy requirements and comply with conservation regulations for areas. It also gives windows that have a superior appearance than the upvc doors repairs alternatives.

Sliding sash windows were initially only used in large buildings or public buildings, though the production process was less expensive and craftsmen were able to produce larger frames with more glass. At the close of the 18th century, sash windows were the most popular wooden style in British homes. As they were easy to open sash windows allowed light into rooms without curtains.

Early windows were plain glass but by the 17th century sash windows started to become more attractive with coloured glass bars and moulded mullions. They were expensive at the time but as glass production became more efficient and cost-effective, they became a part of many of the period homes.

In the 19th century, it was possible to make large, strong glass that did not need support bars. This allowed the frame size to increase further and this in turn allowed for a wider view out of the window. This was an important innovation.

The introduction of the double-hung sliding sash was another important improvement that was made at the end of the I920s and beginning of the I930s. This allowed both the upper and lower sash to be opened simultaneously, and also improved the ventilation of a building.

It is important to maintain the parting bead that separates the sashes. This will prevent rattles and draughts. It is also essential that the idler and sash pulley wheels are kept in good working order as they assist in operating the window.

2. Energy efficiency

As larger and clearer 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 putty on both sides to make them watertight. This form of glazing gradually replaced the leaded light bulbs.

The introduction of sashes created the need for a wider range of ironmongery, with the basic fittings being brass pulleys and lead (and later cast iron) weights, sash stops, shutter hinges and knobs as well as a range of fasteners to hold the sashes in the right place. They were often decorated with motifs, inscriptions, and patterns engraved to identify the maker.

With regular maintenance, sash windows are extremely energy efficient. However, without this maintenance they may become drafty and let in cold air. Draughts can also be caused by the breakdown of paint and putty. You can fix this problem by using wood-to-timber solutions.

The replacement window industry relies on the assumption that older windows are old and beyond repair, while they are able to be maintained with a little attention. Repairs can be costly and cause lots of disruption to the home. Many homeowners choose to replace their windows using PVC-u from a large 'one-stop shop' installation company. They can replace and remove all windows in a house in just one day, avoiding the need to coordinate different tradesmen and making the whole process much quicker. These windows can be equipped with energy-saving' double glazing to achieve more energy efficient ratings than a traditional windows made of sash. However these double-glazed units are unable to duplicate the proportions and section of historic timber sashes.

It is possible to secure traditional windows without compromising their style. Ironmongery like sash chain, mortice bolts and sash lock could be installed. These can be put in place so that the window is still able to be 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 in conjunction with traditional sash window catches. These are best replaced with more robust models, such as those that incorporate double screws or spring levers to decrease the risk of being hit with hammers.

Sash-window frames were typically made from slow-growing deal or, in more elegant homes, from oak. If the glazing bars are still in good condition and are not damaged, they should be left. Where it is possible, the cills of the timber should be replaced with wood that matches. PVC-u companies often offer a one stop shop installation service that can remove and replacing windows across a house in a day without the need to engage other tradespeople or coordinate visits from a number of different suppliers.

Sash windows were first 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 adapted to allow more light into rooms and larger glass panes began to be produced. The result was a more streamlined appearance, and windows with a higher degree of elegance than before.

Sash windows were introduced and required a new type of ironmongery. Early pulleys were constructed out of wood. Later Victorian ones were made of brass or a mixture of wood and leaded. There were also various kinds of knobs and shutter hinges. These ironmongery pieces should be cleaned and preserved to appreciate their beautiful design.

Sashes that don't slide effortlessly.

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

Moisture penetration is a frequent cause of damage to timber windows. This can be avoided by careful painting, regular repairs and elimination of the cause of dampness. The paint can be removed to reveal the soft, decaying wood. The rotten timber sections must be removed with care and the affected area should be snared together or pieced together by using replacements of the same type as the remaining timber. This method of repair maximizes the amount of fabric left, and is one of the least invasive ways of treating decay caused by timber.

A wood condenser made of resin is a viable alternative to traditional staining or sanding. The product is brushed on the surface of the wood to protect it and stabilise it. It is especially useful for treating pulley cords and sash which can help prevent breakage.

It is essential to preserve and not replace any old ironmongery, such as stay latches and sash latches. It can be difficult to replace these items without compromising their original design.
