How to Restore Timber Sash Windows in Cambridge

Replacement-Windows-150x150.jpgMany homes in Cambridge have traditional sash windows and homeowners are proud of how they look. Sash windows can become stuck and are difficult to open and close. This is often due moisture which can cause the timber to expand.

Traditionally, window boxes utilized chains, cotton cords or weights made of lead to operate. Modern sash windows have hidden springs to address this problem.

1. Aesthetics

Timber sash windows, in contrast to PVC-u windows, which are made in imperial sizes, which are modular, can be restored to their original dimensions. This allows the restoration of timber sash windows in order to meet current energy requirements and to comply with conservation area regulations. It also provides an option that is superior to upvc window renovation options.

Sliding sash window frames were initially only used for large buildings or public buildings. However, this changed when production became less expensive and craftsmen could create larger frames using more glass. In the late 18th century sash windows were the dominant wooden style in a majority of British properties. Since they were easy to open sash windows allowed light into rooms without curtains.

The first windows were made of plain glass, but in the 17th century, sash windows were becoming more decorative, with coloured glazing bars and moulded mullions. They were expensive at the beginning but when glass production became less expensive and more efficient, they became commonplace in many period houses.

By the 19th century it was possible to manufacture large, strong glass that didn't require support bars. This allowed the frame's size to increase more, which in turn meant more of a view from the window. This was a significant innovation.

Another important improvement was the introduction of the double-hung sliding windows at the end of I920s and at the beginning of I930s. This allowed both the upper and lower sash to be opened simultaneously, and gave improved ventilation to the building.

Oak was used for older examples and for more prestigious buildings. It is essential to keep the parting bead which divides the sashes. This will stop rattles and draughts. The sash pulleys, idler wheels and sash rollers are also vital to the functioning of the window.

2. Energy efficiency

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

The introduction of sashes led to a need for a much greater variety of ironmongery, with the basic fittings being brass pulleys and lead (and later cast iron) weights, sash stoppers shutter hinges, knobs and shutters and a variety of fasteners that secured the sashes into place. They were often decorated with designs, inscriptions, and engraved patterns to identify the maker.

With regular maintenance, sash windows are extremely energy efficient. However, without this maintenance they can become drafty and let in cold air. Draughts can also be caused by the deterioration of putty and paint. This can be fixed by using wood-to-timber repair products that are specifically designed for this purpose.

The industry of replacement windows relies heavily on the notion that old windows are damaged beyond repair and are not able to be maintained economically. However, they can easily be maintained with a bit of attention. However, these repairs can be costly and cause substantial disruption to the home. To avoid this, many homeowners opt for a complete replacement with PVC-u windows from one the largest 'one stop shop' installation companies. These can remove and replace all the windows in a house in a single day, avoiding the need to coordinate multiple tradesmen and making the entire process much quicker. They can also be supplied with 'energy-saving' double-glazing to get greater energy efficiency than those offered by traditional windows made of sash. However, these double-glazed units cannot duplicate the proportions and section of historic timber sashes.

3. Security

Traditional windows can be made more secure without compromising their appearance. Ironmongery like mortice bolts, sash chain, and sash lock can be used. These can be put in place to ensure that the Plastic window repair is capable of being opened to allow ventilation or cleaning. They are usually discrete since they are made to work with sash windows. They can be used in conjunction with traditional sash window catch. They should be replaced with more robust versions, such as ones that have double screws, or sprung levers, to minimize the chance of being hit with hammers.

Sash-window frames are typically made of oak or slow-grown deal. If glazing bars have survived, they should be kept and if it is it is possible, the timber of the cill should be replaced with identical wood. PVC-u companies typically provide a one-stop shop installation service that can remove and replacing windows across a home in a single day without the need to involve other tradespeople or coordinate visits from a number of different suppliers.

4. Ventilation

Sash windows were introduced in the 17th Century and allowed for a large amount of light to be absorbed into buildings. In the 18th century, they were adapted so that even more light could be let into the rooms. Larger glazing panes were also produced. The result was a much lighter appearance, and windows that had a higher degree of elegance than before.

Sash windows were introduced and required a new range ironmongery. Early pulleys were made of wood. Later Victorian ones were made of brass or a mix of wood and leaded. There were also a variety of types 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 keep them in good condition, wooden windows need to be maintained. Inattention to maintenance can result in:

Sashes that do not slide easily.

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

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

Steel casement windows became popular in the I920s & I930s because they were sturdy and slim, cost-effective and matched the trend of healthy living. Research has proven that softwood sash window are just as effective as PVC-u windows and can even be more attractive.

The window replacement industry has done a lot to persuade house owners that their old windows are old, dirty, and beyond economic repair. However, many older windows made of timber are in good condition and with minor repairs to upvc doors could easily be serviceable for many years to be.

5. Maintenance

The traditional sash windows need regular maintenance and inspection. Failure to do this can lead to the sash cords breaking, a lot of wear on the glazing bars and the deterioration of putty and paint. The removal of sashes could also result in structural movement within the frame that causes the sash to become misaligned and unable to close correctly. The sash could also get stuck in its open position, which allows water and draughts to enter the property.

Damage to timber windows is usually caused by moisture entry. This can be avoided by careful painting, regular repairs and elimination of the source of dampness. Wet rot is easily identified by the wavy look of the existing paint which can be removed to reveal rotting, soft timber. Any rotten timber sections should be cut off and the affected area should be carefully wrapped or pieced back using replacements made from the same type of wood as those remaining. This method of repair increases the amount of fabric retained and is among the least invasive methods of treating decay of timber to timber.

A wood condenser that is based on resin is an alternative to the traditional process of sanding or staining. The product is brushed on to the surface of the timber to help stabilize it and shield it from further damage. It is particularly useful to treat sash and pulley cords, which can help prevent breakage.

It is essential to preserve and not replace any historic ironmongery, such as sash latches and stays. They can be extremely difficult to replace without compromising the the original design. It is also recommended that modern aluminium fittings like sashlifts, as well as chainstays, are avoided since they could cause corrosion and deterioration of timber frames and sashes.
