How to Restore Timber Sash Windows in cambridge windows

Many homes in Cambridge have traditional sash windows and homeowners are proud of the way they appear. Sash windows can get stuck and are difficult to open or close. This is typically due to moisture which can cause the wood to expand.

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

1. Aesthetics

Timber sash windows, in contrast to PVC-u windows which are manufactured in imperial sizes, which are modular, can be restored to their original size. This lets the restoration meet modern day energy requirements while still complying with conservation regulations for the area. It also provides windows with a superior appearance than the upvc locksmith cambridge alternatives.

Sliding sash windows were initially only used in large buildings or public buildings, but this changed as production became cheaper and craftsmen could make larger frames with more glass. At the close of the 18th century, sash windows were the most popular wooden design in British homes. As they were easy to open, sash windows let light into rooms without curtains.

The first windows were made of plain glass, but in the 17th century sash windows started to become more attractive with coloured glass bars and moulded mullions. These windows were quite expensive at the time but as glass production became more efficient and cost-effective, they were a common feature in many of the period homes.

In the 19th century, it was possible to make large, sturdy glass that did not need support bars. This allowed the frame to be enlarged, which in turn gave the viewer a better view. This was a significant innovation.

Another significant improvement was the introduction of the double-hung sliding window at the end of I920s and at the beginning of I930s. The double glazed emergency upvc door repairs seal repairs (My Site)-hung sliding sash is another significant improvement that came about at the end of the I920s and beginning of the I930s.

Oak was used for older examples and for more prestigious buildings. It is important to maintain the separation bead that is used to separate the sashes. This will prevent rattles and draughts. It is also important that sash pulleys and idler wheels are in good working order as they aid in operating the window.

2. Energy efficiency

As larger and clearer sheets of glass were made available, sash windows began to replace hinged casements. Plate glass was set into frames of timber that were rebated, then pinned with glazing sprigs and putty was then sprayed onto the frame's two sides to ensure watertightness. This type of glass gradually replaced leaded lights.

Sashes were introduced, which led to increased demand for ironmongery. The most basic fittings were brass pulleys (and later cast-iron) weights as well as sash stoppers, shutter hinges and handles, and various fasteners used to secure the sashes. These were often decorated in patterns, inscriptions and engraved patterns to identify the maker.

With regular maintenance, sash windows can be extremely energy efficient. Without this maintenance, they can become drafty. Draughts can also result from the degeneration of paint and putty. This can be fixed by making use of wood-to-timber repair tools that are proprietary.

The industry of replacement windows is based on the assumption that old windows are damaged and beyond economical repair, while they can be easily maintained with a little attention. However, repairs to these windows are costly and can cause significant disruption to your home. To prevent this homeowners, many choose to replace their windows with PVC-u windows made by one of the largest "one stop shop" installation companies. They can replace and remove all the windows in a home within a single day, avoiding the need to coordinate multiple tradesmen and making the entire process much faster. They can also be fitted with 'energy-saving' double-glazing, which can achieve more energy efficient ratings than those offered by traditional windows with sash. However double-glazed windows cannot replicate the section and proportions of the sashes made of timber from the past.

3. Security

Traditional windows can be made secure without compromising their style. Ironmongery, such as sash chain, mortice bolts, and sash lock can be used. They can be positioned in a manner that the window can still be open for ventilation and cleaning. These are typically minimal in appearance, as they are designed to complement the sash window. They can be used alongside traditional sash window catches and should be replaced with more robust versions (such ones that have double glazing cambridge screws) or spring levers to decrease the possibility of them being opened by hammering.

Sash-window frames are typically made of oak or slow-grown deal. When glazing bars have survived they should be kept and if it is possible, the timber of the cill should be replaced with the same wood. Many PVC-u firms offer a one-stop shop installation service. They can take out and replace windows on a complete home in one day, without involving any other tradespeople.

4. Ventilation

When sash windows first introduced in the 17th century they allowed a large amount of light into structures. At the end of the 18th century they were altered to allow more light into rooms, and bigger glazing panes started to be made. The result was a lighter look and windows with more elegance.

Sash windows were introduced that required a brand new range ironmongery. Early pulleys were made from wood, whereas later Victorian ones were made from brass or a mixture of lead and wood and there were many kinds of shutter hinges and knobs. The ironmongery pieces need to be maintained and cleaned to appreciate their fine design.

To keep them in good condition, timber windows require regular maintenance. Inattention to maintenance routinely could cause:

Sashes that no longer slide easily.

holes in the frame allow water causing damage and decay.

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

In the I920s and the I930s steel casement windows increased in popularity due to their durability slim and affordable and also matched the fashion for healthy living. Studies have shown that softwood sash window are as efficient as PVC-u windows and can even be more attractive.

The window replacement industry has made a significant effort to persuade house owners that their old windows are dirty, noisy and beyond repair. The truth is that a lot of older windows made of timber are in good condition and, with minor repairs, could easily be repaired for many years to be.

5. Maintenance

The traditional sash windows need regular maintenance and inspection. If you do not maintain your window's sash, it could lead to 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 could also result in structural shifts within the frame, which causes the sash to become misaligned and not closing properly. It is also possible for the sash be stuck or slammed into an open position, which can let water and draughts into the structure.

Moisture penetration is the most common cause of damage to timber windows. This can be prevented by thorough painting, periodic repairs and elimination of the source of dampness. The paint can be removed to expose the soft, rotting wood. Any rotten sections of timber should be cut out and the affected area should be carefully cut or pieced with replacements made from the same type of timber as the ones that remain. This method of repair increases the amount of fabric retained and is among the least invasive methods for treating decay caused by timber.

A wood condenser made of resin is an alternative to the traditional sanding or staining. The product is brushed on the surface of the wood to protect it and stabilise it. It is especially useful to treat sash and pulley cords, where it can prevent breakage.

It is crucial that any historic ironmongery like sash stays and latches are kept and restored rather than replaced. These items are difficult to replace without harming the quality of the original design. It is also recommended that modern fittings made of aluminium, such as sashlifts and chainstays, be avoided as they can cause deterioration and corrosion of timber frames and sashes.
