How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge have sash windows that are traditional and homeowners are proud of how they appear. Sash windows can become stuck and are difficult to open or shut. This is often due to moisture which can cause the timber to expand.

Traditionally, window boxes utilized chains or cotton cord and lead weights to operate. Modern sash window springs are hidden to eliminate this issue.

1. Aesthetics

Contrary to PVC-u windows which are made to modular imperial sizes the timber sash windows are able to be restored to their original size. This lets the restoration meet the current energy standards while ensuring compliance with conservation areas regulations. It also offers windows with a superior appearance than the uPVC alternatives.

Sliding frames for windows made of sash were originally only used in large buildings or public buildings. However the production became cheaper and artisans could produce larger frames with more glass. By the late 18th century sash windows were the dominant wooden style in a majority of British homes. double glazing cambridge were easy 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 began to become more decorative with coloured glazing bars and moulded mullions. They were expensive at the beginning but as glass production became cheaper and more efficient, they became an integral feature in many homes of the period.

In the 19th century, it became possible to produce large, sturdy glasses that did not require supporting bars. This allowed the frame to be made larger which, in turn, provided the viewer a better view. This was a very important advancement.

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

The most common type of sash is constructed of slow-growing deal (pine) however oak was utilized in more luxurious buildings and in earlier examples. A split bead divides the two sashes. It is important that this is maintained in order to avoid rattles and draughts. It is also crucial that the idler and sash pulley wheels are in good working order as they assist in operating the window.


2. Energy efficiency

Sash windows were replaced by hinged casements as clearer and larger sheets were made available. Plate glass was set into frames of timber that were rebated, then pinned with glazing sprigs and putty was then sprayed onto both sides of the frame for watertightness. This kind of glass gradually replaced led lights.

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

With regular maintenance, sash windows can be very energy efficient. If they are not maintained, they can become drafty. Putty and paint can cause draughts too. This can be remedied by making use of wood-to-timber repair tools that are proprietary.

The replacement window industry relies heavily on the notion that older windows are beyond repair and are not able to be maintained economically. However windows can be easily maintained with a little attention. However, these repairs can be costly and cause significant disruption to your home. To avoid this homeowners, many prefer to replace their windows with PVC-u windows from one of the largest 'one stop shop' installation companies. They can replace all windows in a house in a single day, saving time and avoiding the need for different tradesmen to coordinate. They can also be fitted with energy-saving double-glazing to achieve more energy efficient ratings than traditional windows made of sash. Double-glazed windows aren't able to replicate the proportions and section of sashes from old timber.

3. Security

Traditional windows can be secured without compromising their aesthetics. Ironmongery, such as mortice bolts, sash chain and sash locks can be used. They can be positioned in a manner that the window can still be opened for ventilation and cleaning. These windows are typically unobtrusive as they are designed to complement sash windows. They can be used alongside traditional sash-window catches, which must be replaced by more robust models (such ones with double screws) or sprung levers to reduce the chance of them being hammered open.

Sash-window frames are traditionally made from oak or slow-grown deal. If the glazing bars remain intact and are not damaged, they should be left. Where possible, the timber cills should be replaced with wood that is in line with. Many PVC-u firms offer a one-stop shop installation service. They can remove and replace windows on a complete home in one day, without involving any other tradespeople.

4. Ventilation

Sash windows were introduced in the 17th Century and allowed for a large amount of light to enter buildings. At the end of the 18th century they were modified to let more light into rooms and larger glazing panes began to be produced. The result was a much more streamlined appearance, and windows with a greater quality of design than before.

Sash windows were introduced, which required a new range ironmongery. Early pulleys could be made out of wood. Later Victorian ones were made of brass or a combination of leaded and wood. There were also various kinds of shutter hinges and knobs. Ironmongery elements must be maintained and cleaned to ensure that the exquisite quality of their design can be appreciated.

Timber windows require careful maintenance to ensure they remain in good condition. A lack of regular attention can lead to:

Sashes that no longer slide easily.

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

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

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

The replacement window industry was able to convince homeowners that their old windows were rotten and drafty. They were also beyond the budget for repair. The reality is that many old timber windows are in good shape and with minor repairs can easily be maintained for years to come.

5. Maintenance

A traditional sash window requires regular maintenance and inspection. Failure to do this can result in sash cords breaking, excessive wear on the glazing bars, and degradation of the paint and putty. The removal of sashes could also result in structural movement within the frame, which can cause the sash to not close correctly. It is also possible for the sash to be snagged or fixed in an open position, which can let water and draughts into the structure.

Damage to timber windows is often caused by water penetration. This can be avoided by careful painting, regular repairs, and removing the source of dampness. Wet rot can be identified by the wavy appearance of the paint that can be stripped to reveal soft, rotting wood. The rotten timber sections should be carefully cut out and the affected part should be snared together or glued together using replacements of the same type as the remaining timber. This method of repair maximizes the amount original fabric and is one of least invasive ways to treat wood-to-timber rot.

A wood condenser made of resin is a viable alternative to traditional process of sanding or staining. It is brushed onto the surface of the wood to protect it and strengthen it. It is especially beneficial for the treatment of sash and pulley cords, which can help prevent breakage.

It is important to restore and not replace any old ironmongery such as stay latches and sash latches. They can be extremely difficult to replace without compromising the the original design. It is also recommended that modern fittings made of aluminium, such as sashlifts and chainstays, should be avoided since they can cause deterioration and corrosion of timber frames and sashes.
