Many homes in Cambridge have sash windows that are traditional and homeowners are proud of their appearance. However, sash windows may get stuck and be difficult to open or close. This is often due moisture, which can cause the timber to swell.

Traditionally, upvc window renovation boxes used chains, cotton cords or lead weights to operate. Modern sash windows come with hidden springs to solve this issue.

1. Aesthetics

In contrast to PVC-u windows, which are manufactured according to the modular imperial size 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 comply with conservation regulations for areas. It also gives windows with a superior appearance than upvc Doors Repairs alternatives.

Sliding sash window frames were initially only used for large buildings or public buildings. However, this changed when production became cheaper and artisans could produce larger frames with greater 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 allowed light into rooms without curtains.

Early windows were simple glass, but in the 17th century sash windows began to become more decorative with coloured glazing bars and moulded mullions. These were very expensive at the time but as glass repair cambridge production improved and less expensive, they became a feature of many of the period homes.

In the 19th century, it became possible to create large, sturdy glasses that didn't require support bars. This allowed the frame size to be enlarged more, which in turn meant more of a view from the window. This was an important innovation.

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

The most popular kind of sash is made from slow grown deal (pine) but oak was also used in more expensive buildings as well as in some earlier examples. A split bead divides the two sashes, and it is essential that it is maintained in order to avoid rattles and drafts. The sash pulleys, idler wheels and sash rollers are crucial for the proper operation of the window lock repairs.

2. Energy efficiency

As clearer and larger glass sheets were made available, sash windows started replacing hinged casements. They were glazed with plate glass set in timber frames with rebates and pinned in place using glazing sprigs, with putty on both sides to make them watertight. This form of glazing gradually replaced leaded lights.

The introduction of sashes resulted in the need for a larger variety of ironmongery including the most basic fittings, brass pulleys, lead (and later cast iron) weights, sash stoppers shutter hinges, knobs and shutters and a variety of fasteners used to keep the sashes to their the right place. They were often decorated with motifs, inscriptions, and engravings to identify the maker.

With regular maintenance, sash windows can be very energy efficient. But, if you don't maintain them, they can become draughty and let in cold air. Draughts can also be caused by the deterioration of paint and putty. This can be corrected making use of wood-to-timber repair tools that are proprietary.

The replacement window industry relies on the assumption that old windows are damaged and beyond repair, but they are able to be maintained with a bit of care. However, these repairs are costly and can cause substantial disruption to the home. To prevent this, many homeowners 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 house in a single day, avoiding the need to coordinate different tradesmen, making the whole process much quicker. These windows can be fitted with 'energy-saving' double glazing to achieve higher energy ratings than the traditional windows made of sash. These double-glazed units are not capable of resembling the proportions and sections of the sashes made of timber from the past.

3. Security

It is possible to secure traditional windows without compromising their appearance. Many types of ironmongery are available, including sash chains, mortice bolts and sash locks. These can be installed in such a way that the window is able to be opened to allow ventilation and cleaning. These are typically minimal in appearance, as they are designed to match the sash window. They can be used with traditional sash window catches. They should be replaced with more robust models like those with double screws or sprung levers, to minimize the risk of being struck by hammers.

Sash-window frames are traditionally constructed from oak or slow-grown deal. If the glazing bars are in good condition and in good condition, they should be kept. If it is feasible, the cills made of timber should be replaced with wood that is in line with. Many PVC-U companies offer a one-stop shop installation service. They can take out and replace windows throughout a home in 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 even more light into rooms and bigger glazing panes started to be made. The result was a lighter appearance, and windows that had a higher level of elegance than they had before.

Sash windows were introduced that required a brand new range ironmongery. Early pulleys were made from wood, later Victorian ones could be 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 cleaned and preserved to appreciate their beautiful design.

Timber windows require regular maintenance to keep them in good order. Inattention to maintenance routinely could lead to:

Sashes that do not slide smoothly.

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

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

Steel casement windows became popular in the I920s & I930s because they were strong and slim, and also because they were cheap and matched the trend towards healthy living.

A traditional sash window requires regular maintenance and inspection. If you do not maintain your sash window, it could lead to the sash cords breaking, and the glazing bars deteriorating excessively. It could also cause the paint and putty to degrade. The removal of sashes can also result in structural movements within the frame, causing the sash to not close correctly. The sash can also be stuck in an open position, allowing water and draughts into the building.

Damage to windows made of timber is usually caused by moisture entry. This can be prevented by careful painting, regular repairs, and removing the source of dampness. Wet rot can be identified due to the wavy appearance of the paint, which can be stripped away to reveal soft, rotting timber. The sections of timber that are rotten should be carefully removed, and the affected area should be snared together or glued together with replacements of the exact kind as the timber that remains. This method of repair maximizes the amount of fabric left, and is among the least invasive methods of treating timber-to-timber decay.

A wood condenser made of resin is an alternative to traditional sanding or staining. This is brushed on the surface of the wood to protect it and stabilise it. It is particularly useful to treat sash and pulley cords, which can stop breakage.

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