How to Restore Timber Sash Windows in Cambridge

Many homes in cambridge windows and doors have sash windows that are traditional and homeowners are proud of their appearance. Sash windows can become stuck and be difficult to open and close. This is usually due to moisture, which can cause the timber to swell.

Box sash windows were traditionally operated by chains or cotton cords as well as lead weights. Modern window springs for sash windows are concealed to avoid this issue.

1. Aesthetics

Timber sash windows, unlike PVC-u windows that are made in imperial sizes, which are modular, are able to be restored to original dimensions. This permits the re-installation of timber sash windows in order to comply with current energy standards and to comply with conservation area regulations. It also gives windows with a superior appearance than the upvc window lock repair upvc door repair handle repairs near me (just click the next post) alternatives.

Sliding sash windows were originally only used in large structures or public buildings, but the production process became cheaper and craftsmen could make larger frames with more glass. In the late 18th century sash windows were the dominant wooden design in most British properties. Sash windows were easy to operate and let light in rooms without the need for curtains.

The first windows were made of plain glass, but by the 17th century, sash windows began to become more decorative with coloured glazing bars and moulded mullions. They were expensive at the time, but as glass production improved and cost-effective, they were a common feature in numerous period houses.

In the 19th century, it became possible to produce large, strong glasses that did not require supporting bars. This allowed for the frame to be made bigger which, in turn, provided a better view. This was a significant innovation.

The introduction of the double-hung sliding sash is another important improvement that was made in the I920s and the beginning of the I930s. This allowed both the lower and upper sash to be opened simultaneously, and allowed for better ventilation to the building.

The most commonly used type of sash is made of slow-growing deal (pine) but oak was also used in more luxurious buildings and in some earlier examples. A parting bead separates the two sashes and it is vital that it is maintained in order to avoid rattles and drafts. The idler wheels, sash pulleys and sash rollers are vital to the operation of the window.

2. Energy efficiency

As larger and clearer glass sheets were made available, sash windows began to replace hinged casements. Plate glass was placed in frames of timber that were rebated, then which were pinned with glazing sprigs, and putty was then sprayed onto both sides of the frame to ensure watertightness. This form of glazing gradually replaced led lights.

The introduction of sashes created the need for a 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 used to keep the sashes to their the right place. These were often decorated in designs, inscriptions, and engraved patterns to identify the maker.

Sash windows can be very energy efficient when they are maintained regularly. But, if you don't maintain them, they can become draughty and let in cold air. Draughts can also result from the degeneration 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 perception that old windows are damaged and beyond repair, but they can be maintained with a bit of care. These repairs can be costly and cause many disruptions in the home. Many homeowners opt to replace their windows with PVC-u from a 'one-stop shop' installation company. They can take down and replace all the windows in a home within a single day, eliminating the need to coordinate different tradesmen and making the whole process much more efficient. They can also be supplied with 'energy saving' double-glazing to get more energy efficient ratings than those offered by traditional sash windows. These double-glazed windows aren't able to replicate the proportions or section of the sashes made of timber from the past.

3. Security

Traditional windows can be secured without compromising their style. Ironmongery like mortice bolts, sash chain, and sash lock can be put in place. They can be positioned in a manner that the window repair can be opened to allow ventilation and cleaning. These windows are typically unobtrusive as they are designed to work with sash windows. They can be utilized in conjunction with traditional sash-window catches and must be replaced by more robust models (such as those incorporating double screws) or sprung levers to reduce the possibility of them being opened by hammering.

Sash-window frames are typically made of oak or slow-grown deal. If glazing bars have survived, they should be kept, and where possible, the timber of the cill should be replaced with identical wood. PVC-U companies usually offer a one stop shop installation service that can remove and replacing windows on an entire house in a day without the need to engage other tradespeople, or coordinate visits from different suppliers.

4. Ventilation

When sash windows were first introduced in the 17th century, they allowed a substantial amount of light to flood into buildings. By the end of the 18th century, they were modified to let even more light into rooms and larger glazing panes began to be made. The result was a lighter look and windows with more elegance.

The introduction of sash windows also required a new range of ironmongery. Early pulleys were of wood, later Victorian ones could be made of brass or a mixture of lead and wood and there were many kinds of shutter hinges and knobs. Ironmongery elements must be maintained and cleaned to ensure that the exquisite quality of their design can be appreciated.

Timber windows require careful maintenance to keep them in good shape. Lack of attention to them regularly can result in:

Sashes that do not slide easily.

Holes in the frame that allow water to get in and cause decay and damage.

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

Steel casement windows became popular in the I920s and I930s because they were sturdy and slim, and also because they were cheap and complemented the trend for healthy living. Research has shown that softwood sash window are just as efficient 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 rotten drafty, noisy and beyond repair. The reality is that many old windows made of wood are in good condition and with minor upvc door repairs can easily be serviceable for many years to come.

5. Maintenance

A traditional sash window needs regular maintenance and inspection. Inability to maintain it properly could result in sash cords breaking, excessive wear on the glazing bars, and degradation of the paint and putty. The removal of sashes could also result in structural movement within the frame, which can cause the sash not to close properly. The sash may also become stuck in the open position, allowing the water and drafts to enter the building.

Moisture penetration is a frequent cause of damage to windows made of timber. This can be prevented by regular maintenance by thorough painting and eliminating the cause of dampness. Wet rot can be identified by the wavy appearance of the existing paint which can be stripped away to reveal soft, rotting wood. The rotten timber sections should be carefully removed and the affected area should be snared together or glued together by using replacements of the same type as the remaining timber. This method of repair increases 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 process of sanding or staining. It is brushed onto the surface of the wood to protect it and stabilise it. It is especially useful for the treatment of sash and pulley cords, where it can prevent breakage.

It is crucial to restore and not replace any historical ironmongery, such as stay latches and sash latches. It is difficult to replace these items without altering their original design. It is also advised that fittings made of aluminum, such as sashlifts and chainstays, be avoided as they could cause corrosion and deterioration of timber frames and sashes.
