How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge have traditional sash windows and homeowners are proud of the way they look. However, sash windows may become stuck and difficult to open or close. This is usually due to moisture that can cause the timber to expand.

Box sash windows were traditionally operated by chains or cotton cords, as well as lead weights. Modern sash windows feature hidden springs to overcome this problem.

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 dimensions. This allows the restoration of timber sash windows in order to comply with current energy standards and to comply with conservation area regulations. It also provides 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 less expensive and craftsmen could make larger frames with more glass. By the late 18th century sash windows were the dominant design of wood in the majority of British homes. As they were easy to open sash windows allowed light into rooms without the need for curtains.

Early windows were plain glass, but by the 17th century, sash windows started to become more decorative with coloured glazing bars and moulded mullions. These were very expensive at the time, but as glass production improved and less expensive, they became a part of many of the period homes.

In the 19th century it was possible to create large, strong glass that didn't require support bars. This allowed the frame's size to be enlarged further and this in turn meant more of a view from the window. This was an important advancement.

The introduction of the double-hung sliding sash is another significant improvement that came about towards the end of the I920s and at the beginning of the I930s. The double-hung sliding sash is another important improvement that was made at the end of the I920s and at the beginning of the I930s.

The most common type of sash is made from slow-growing deal (pine) however oak was utilized in more prestigious buildings and in earlier examples. It is essential to keep the separation bead that separates the sashes. This will prevent draughts and rattles. It is also crucial that the idler and sash pulley wheels are kept in good working order as they help to operate the window.

2. Energy efficiency





As clearer and larger sheets of glass were made available, sash windows started replacing hinged casements. They were coated with plate glass that was set within rebated timber frames and secured with glazing sprigs, with putty on both sides to create a watertight seal. This form of glazing gradually superseded the leaded light bulbs.

upvc repairs Repair My Windows And Doors were introduced, which led to increased demand for ironmongery. The most common fittings included brass pulleys (and later cast-iron) weights and stoppers for sashes, shutter hinges and handles as well as a variety of fasteners to fix the sashes. These were often decorated with motifs, inscriptions or engraved patterns that identified the maker.

With regular maintenance, sash windows can be extremely energy efficient. However, without this maintenance they may become drafty and let in cold air. Putty and paint can cause draughts. This can be remedied by using proprietary wood-to-timber repair products.

The replacement window industry relies heavily on the belief that old windows are damaged beyond repair and cannot be maintained economically. However, they can easily be maintained with a bit of attention. However, repairs to these windows can be costly and cause considerable disruption to the home. Many homeowners opt to replace their windows using PVC-u from a huge "one-stop shop" installation company. They can replace all windows in a home in a single day, saving time and avoiding the need for multiple tradesmen to coordinate. They can also be supplied with 'energy-saving' double-glazing, which can achieve greater energy efficiency than traditional windows made of sash. These double-glazed units are not able to replicate the proportions and sections of historic timber sashes.

3. Security

It is possible to secure windows that are traditional without compromising on their aesthetics. Many types of ironmongery can be fitted, including sash chains, mortice bolts and locks for sash. They can be positioned in such a way that the window is able to be opened for ventilation and cleaning. These products are often unobtrusive as they are designed to be used in conjunction with sash windows. They can be used in conjunction with traditional sash window catches that should be replaced with more robust models (such ones with double screws) or spring levers to decrease the chance of them being hammered open.

Sash-window frames were made from slow-growing deal or, in more elegant homes they were made from oak. If the glazing bars remain in good condition, they should be retained. If feasible, the cills made of timber should be replaced with wood that is in line with. PVC-u companies often offer a one stop shop installation service, which includes removing and replacing windows across a home in a single day without the need to involve other tradespeople or co-ordinate various visits from a number of different suppliers.

4. Ventilation

When sash windows were first introduced in the 17th century they allowed a large amount of light to flood into structures. By the end of the 18th century, they were adapted to allow even more light into rooms and larger glass panes began to be manufactured. The result was a lighter look and windows that were more elegant.

Sash windows were introduced and required a new type of ironmongery. Early pulleys were of wood, later Victorian ones were made of brass or a combination of lead and wood and there were many kinds of shutter hinges and knobs. The ironmongery components should be retained and cleaned down to ensure that the exquisite quality of their design can be appreciated.

To ensure they remain in good shape, timber windows must be maintained. A lack of regular attention can lead to:

Sashes that do not move easily.

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

break down of putty, allowing water penetration that can lead to decay in the frame and cill.

In the I920s and the I930s steel casement windows gained popularity because they were strong slim and inexpensive, and complemented the vogue for healthy living. Studies have shown that softwood sash windows are just as efficient as PVC-u windows and can even be more attractive.

The industry of replacement windows has done a lot to persuade house owners that their windows are rotten, draughty and beyond economic repair. Many old windows made of timber can be fixed and used for a long time with minor repairs.

5. Maintenance

Traditional sash windows require regular maintenance and inspection. If you don't maintain your sash window, it can cause the sash cords breaking and the glazing bars wearing out excessively. It can also cause paint and putty to degrade. The removal of the sashes can also result in structural movement within the frame which causes the sash to be misaligned and not closing properly. The sash could also get stuck in an open position, allowing water and draughts into the property.

Moisture penetration is a common cause of damage to timber windows. This can be avoided with regular maintenance as well as thorough painting, and then removing the source of dampness. Wet rot can be identified by the wavy look of the paint that can be stripped to reveal rotting, soft timber. The sections of timber that are rotten must be removed with care and the affected part should be scarfed together or pieced together by using replacements of the same type as the remaining timber. This method of repair increases the amount of original fabric left, and is one of the least invasive methods for treating decay caused by timber.

A resin-based wood condenser is a viable alternative to traditional staining or sanding. This is brushed onto the surface of the wood to stabilise and shield it from further damage. It is particularly beneficial for the treatment of pulleys and sash cords which help prevent the breakage.

It is essential to preserve and not replace any old ironmongery such as sash latches and stays. These items can be very difficult to replace without damaging the the original design. It is also advised that fittings made of aluminum, such as sashlifts and chainstays, should be avoided since they can cause deterioration and corrosion of timber frames and sashes.
