A Brief History History Of Sash Windows Cambridge

How to Restore Timber Sash Windows in Cambridge

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

Traditionally, box sash windows utilised chains or cotton cord and lead weights to operate. Modern sash windows feature hidden springs to address this issue.

1. Aesthetics

Unlike PVC-u windows that are manufactured according to imperial sizes that are modular Timber sash windows can be restored to their original sizes. This allows the restoration to meet modern day energy requirements while complying with conservation regulations for the area. It also offers a window seal replacement near me with a far superior appearance than the emergency upvc door repairs window repair renovation (marvelvsdc.faith) alternatives.

Sliding sash window doctor frames were initially only used for large buildings or public buildings. However this changed as production became less expensive and craftsmen could produce larger frames with greater glass. In the late 18th century Sash windows were the most popular design of wood in the majority of British properties. As they were easy to open, sash windows let 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. They were expensive at first, but as glass production became cheaper and more efficient, they became a common feature in many homes of the period.

By the 19th century it was possible to make large, sturdy glass that did not require supporting bars. This allowed for the frame to be enlarged and, in turn, gave the viewer a better view. This was an important advancement.

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

The most popular type of sash is made of slow-growing deal (pine) however oak was also used in more luxurious buildings and in some earlier examples. A split bead divides the two sashes, and it is important that this is well maintained to prevent rattles and draughts. The idler wheels, sash pulleys and sash rollers also are crucial for the proper operation of the window repair.

2. Energy efficiency

Sash windows replaced hinged cases as clearer and larger sheets were made available. They were coated with plate glass that was set within rebated timber frames and secured with glazing sprigs, with putty on both sides to make them watertight. This form of glass gradually replaced the leaded light bulbs.

Sashes were introduced, which resulted in a greater demand for ironmongery. The most common fittings included brass pulleys (and later cast-iron) weights as well as sash stoppers shutter hinges and handles, and a variety of fasteners used to fix the sashes. They were often decorated with motifs, inscriptions, and engraved patterns that identified the maker.

Sash windows are energy-efficient with regular maintenance. If they are not maintained they can get noisy. Draughts can also be caused by the deterioration of paint and putty. This issue can be fixed with wood-to-timber products.

The industry of replacement windows 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 avoid this, many homeowners choose 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 home in a single day, saving time and avoiding the need for different tradesmen to coordinate. They are also available with 'energy-saving' double-glazing, which can achieve higher energy efficiency ratings than those offered by traditional windows with sash. Double-glazed windows aren't capable of resembling the proportions and sections of sashes from old timber.

3. Security

It is possible to secure traditional windows without compromising their appearance. Many types of ironmongery can be installed including sash chains mortice bolts and sash locks. They can be fitted in a manner that the window can be open for ventilation and cleaning. These products are often discrete since they are made to work with sash windows. They can be used alongside traditional sash-window catchers and should be replaced with more robust versions (such ones that have double screws) or spring levers to decrease the chance of them being hammered out.

Sash-window frames were made from slow-growing deal or, in the more elegant homes made of oak. If glazing bars have survived, they should be kept and if it is possible, the timber of the cill should be replaced by identical wood. Many PVC-u firms provide a one-stop shop installation service. They can take down and replace windows throughout a house in just one day, without the need to involve other tradespeople.

4. Ventilation

When sash windows first introduced in the 17th century, they allowed a significant amount of light into structures. 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 lighter appearance and windows that were more elegant.

The introduction of sash windows also demanded the creation of a new line of ironmongery. Early pulleys were made out of wood. Later Victorian ones were made of brass or a combination of wood and lead. There were also a variety of kinds of knobs and shutter hinges. The ironmongery components should be kept and cleaned so that the fine quality of their design can be appreciated.

To ensure they remain in good condition, wooden windows must be maintained. A lack of regular attention can result in:

Sashes that don't slide smoothly.

holes in the frame that admit water, which can cause damage and decay.

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

In the I920s and the I930s steel casement windows increased in popularity due to their strength, slim and cheap and also matched the fashion for healthy living. However, research has proven that traditional softwood sash windows are just as efficient thermally as PVC-u double-glazed windows, and may be more appealing than the modern sleek design of casement windows.

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

5. Maintenance

A traditional sash window requires regular maintenance and inspection. Failure to do this can lead to broken sash cords, excessive wear on the glazing bars, and deterioration of paint and putty. The removal of sashes may also cause structural movement in the frame, causing the sash not to close properly. The sash may also become stuck in its open position, allowing the water and drafts to enter the property.

Damage to windows made of timber is often caused by water penetration. This can be prevented by thorough painting, periodic repairs and elimination of the source of dampness. Wet rot is easily identified due to the wavy appearance of the paint that can be stripped away to reveal soft, rotting timber. Any rotten sections of timber must be removed and the affected area should be carefully cut or pieced with replacements made of the same kind of timber as the ones remaining. This method of repair maximizes the amount of fabric that was originally used and is among the least invasive ways to treat wood-to-timber rot.

A wood condenser that is based on resin is an alternative to traditional sanding or staining. It is brushed onto the surface of the wood to protect it and strengthen it. It is particularly beneficial for the treatment of sash cords and pulleys which can help prevent breakage.

It is important that any ironmongery from the past such as sash stay and latches are retained and restored instead of replacing them. It can be difficult to replace these items without altering their original design. It is also recommended that fittings made of aluminum, such as sashlifts and chainstays, be avoided as they can cause corrosion and deterioration of timber frames and sashes.
