How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge have sash windows with traditional designs and homeowners are proud of the way they look. Sash windows can become stuck and are difficult to open or close. This is usually due to moisture, which can cause the wood to swell.

Box sash windows were historically operated using chains or cotton cords, as well as lead weights. Modern sash windows have hidden springs to solve this problem.

1. Aesthetics

Unlike PVC-u windows that are manufactured according to the modular imperial size, timber sash windows can be restored to their original size. This allows the restoration to be in line with modern energy requirements while ensuring compliance with conservation area regulations. It also comes with a window that is far superior to upvc doors repairs alternatives.

Sliding frames for windows made of sash were originally only used in large buildings or public buildings. However this changed as production became more affordable and artisans could make larger frames using more glass. In the late 18th century sash windows were the dominant design of wood in the majority of British homes. Sash windows were easy to operate and let light into rooms without the need for curtains.

The first windows were made of glass that was plain however, in the 17th century sash windows started to be more decorative. They were initially made of colored glazing bars, also known as mullions. These windows were quite expensive at the time, but as glass production became more efficient and cheaper they became a feature of many of the period homes.

In the 19th century, it was possible to create large, sturdy glass that did not require supporting bars. This allowed for the frame to be enlarged, which in turn gave a better view. This was a significant advancement.

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

Oak was used in older examples and for more prestigious buildings. It is essential to keep the parting bead which divides the sashes. This will stop draughts and rattles. It is also essential that the idler and sash pulley wheels are in good working order as they assist in operating the Energy-Efficient window repair.

2. Energy efficiency

As larger and clearer sheets of glass became available, sash window started replacing hinged casements. They were glazed with plate glass placed within timber frames with rebates and secured with glazing sprigs, with putty on both sides to create a watertight seal. This kind of glazing gradually replaced leaded lights.

The introduction of sashes resulted in the need for a wider range of ironmongery, with the most 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 used to keep the sashes into place. These were often decorated in motifs, inscriptions, and engravings to identify the maker.

Sash windows can be extremely energy efficient when they are maintained regularly. However, if they are not maintained, they may become drafty and let in cold air. Draughts can also be caused by the breakdown of putty and paint. This can be remedied by using proprietary wood-to-timber repair products.

The industry of replacement windows relies heavily on the perception 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, repairs to these windows can be costly and cause considerable disruption to the home. Many homeowners choose to replace their windows with PVC-u from a huge "one-stop shop" installation company. They can replace all windows in a home in one day, thereby saving time and avoiding the need for various tradesmen to coordinate. These windows can be fitted with 'energy-saving double-glazing to attain higher energy ratings than the traditional windows with sash. These double-glazed units are not capable of replicating the proportions and sections of sashes from old timber.

3. Security

It is possible to secure traditional windows without compromising their style. Ironmongery like sash chain, mortice bolts, and sash lock can be put in place. These can be put in place so that the window is capable of being opened to allow ventilation or for cleaning. These windows are typically discrete since they are made 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 versions (such ones with double screws) or spring-loaded levers to minimize the chance of them being hammered open.

Sash-window frames were typically made from slow-growing deal or, in the more luxurious homes they were made from oak. If the glazing bars are still in good condition and in good condition, they should be kept. If it is possible, the cills of the timber should be replaced with wood that matches. PVC-U companies usually offer a one stop shop installation service, which includes removing and replacing windows on a complete house in a day without the need to engage other tradespeople or coordinate visits from different suppliers.

4. Ventilation

Sash windows were introduced in the 17th century and allowed for a huge amount of light to enter buildings. At the end of the 18th century, they had been adapted so that even more light could be let into rooms. Larger glazing panes were also produced. The result was a lighter appearance and windows that were more elegant.

Sash windows were introduced that required a brand new type of ironmongery. Early pulleys could be made of wood. Later Victorian ones were made of brass or a combination of wood and lead. There were also various types of knobs and shutter hinges. The ironmongery pieces need to be cleaned and preserved to appreciate their exquisite design.

To ensure they remain in good condition, timber windows must be maintained. Inattention to maintenance can lead to:

Sashes that do not move easily.

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

break down of putty, allowing water penetration that could cause decay in the frame and cill.

In the I920s and I930s steel casement windows gained popularity because they were strong slim and affordable and also matched the fashion for healthy living. Research has proven that softwood sash windows are just as effective as PVC-u windows, and may even be more attractive.

The industry of replacement windows was able to convince homeowners that their old windows were decayed drafty, noisy and beyond repair. Many old windows made of timber can be fixed and utilized for a longer period with minor repairs.

5. Maintenance

A traditional sash window requires regular maintenance and inspection. If you don't maintain your window's sash, it could result in the sash cords breaking and the glazing bars wearing out excessively. It can also cause paint and putty to become damaged. The removal of the sashes may also cause structural movement within the frame that causes the sash to move out of alignment and unable to close correctly. It is also possible for the sash to be stuck or fixed in the open position, which can let water and draughts into the property.

The damage to timber windows is usually caused by moisture infiltration. This can be avoided by thorough painting, periodic repairs and the elimination of the cause of dampness. The paint can be removed to expose the soft, decaying wood. Any rotten timber sections must be removed and the affected area carefully scarfed or pieced in using replacements made of the same type of wood as those remaining. This method of upvc door repair increases the amount original fabric and is one of least invasive ways to treat timber-to-timber rot.

The use of a resin-based wood consolidant is an alternative to the traditional method of staining and sanding. It is brushed onto the surface of the wood to protect it and strengthen it. It is especially beneficial for treating pulley cords and sash which can help prevent breakage.

It is important that any ironmongery from the past such as sash stay and latches are retained and restored rather than replaced. These items are difficult to replace without compromising the quality of the original design. It is also advised that modern fittings made of aluminium, such as sashlifts and chainstays, should be avoided since they can cause corrosion and deterioration of timber frames and sashes.
