1. Aesthetics

Timber sash windows, in contrast to PVC-u windows, which are made in imperial sizes and are modular, are able to be restored to their original size. This allows the restoration of timber sash windows to meet the current energy requirements and comply with conservation area regulations. It also gives windows that have a superior appearance than uPVC alternatives.

Sliding sash windows were initially only found in large buildings or public buildings, though this changed when production became less expensive and craftsmen could produce larger frames with more glass. By the end of the 18th century, sash windows had become the most popular wooden design in British homes. As they were easy to open sash windows allowed light into rooms without the need for curtains.

The early windows were made of plain glass However, in the 17th century, sash windows began to become more attractive. They started with coloured glazing bars or mullions. They were expensive at the beginning but as glass production became cheaper and more efficient, they were commonplace in many homes of the period.

In the 19th century, it became possible to create large, strong glasses that did not require support bars. This allowed for the frame to be made larger and, in turn, gave a better view. This was an important innovation.

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

Oak was used for older examples and more prestigious buildings. It is important to maintain the parting bead which divides the sashes. This will prevent rattles and draughts. It is also essential that the idler and sash pulley wheels are in good working order as they assist in operating 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 frames of timber that were rebated, then pinned with glazing sprigs and putty was sprayed on the frame's sides to ensure watertightness. This type of glass gradually replaced the leaded light bulbs.

The introduction of sashes led to an need for a wider range of ironmongery, including the most basic fittings, brass pulleys, lead (and later cast iron) weights, sash stoppers shutter hinges and knobs and a variety of fasteners to hold the sashes in place. These were often decorated in motifs, inscriptions, and patterns engraved to identify the maker.

Sash windows can be extremely energy efficient if they are maintained regularly. Without this maintenance, they can become noisy. Draughts can also result from the degeneration of paint and putty. It is possible to fix this issue by using wood-to-timber solutions.

The replacement window industry relies heavily on the belief that old windows are beyond repair and cannot be maintained economically. However they can be maintained with a bit of attention. However, repairs to these windows are costly and can cause considerable disruption to the home. To avoid this homeowners often prefer to replace their windows with PVC-u windows from one the many "one-stop shop" installation companies. They can replace all windows in a house in one day, saving time and eliminating the need for different tradesmen to coordinate. They can also be fitted with 'energy saving' double-glazing, which can achieve greater energy efficiency than are possible with traditional windows made of sash. These double-glazed windows aren't able to replicate the proportions and sections of the sashes made of timber from the past.

3. Security

It is possible to secure windows that are traditional without compromising on their aesthetics. Ironmongery like mortice bolts, sash chain, and sash lock can be installed. They can be fitted in such a way that the window seal replacement near me can be open for ventilation and cleaning. They are generally not noticeable, since they are designed to match the sash window. They can be utilized in conjunction with traditional sash window catches that should be replaced with more robust models (such ones that have double screws) or spring-loaded levers to minimize the risk of them being opened by hammering.

Sash-window frames were typically constructed from slow grown deal or, in more luxurious homes made of oak. If the glazing bars remain intact and in good condition, they should be kept. If it is possible, the cills of the timber should be replaced with wood that is in line with. Many PVC-U companies offer a one-stop installation service. They can remove and replace windows on a complete house in just one day, without involving any other tradespeople.

4. Ventilation

When sash windows first introduced in the 17th century, they allowed a significant amount of light to flood into buildings. At the end of the 18th century, they were modified to allow more light could be let into rooms. Larger glass panes were also created. The result was a much lighter appearance and windows with a greater degree of elegance than before.

The introduction of sash windows also demanded a new range of ironmongery. Early pulleys were made from wood, whereas later Victorian ones could be made of brass or a mixture of lead and wood and there were various types of shutter hinges and knobs. These ironmongery elements should always be retained and cleaned down so that the quality of their design can be appreciated.

Timber windows require careful maintenance to ensure they remain in good shape. Inattention to maintenance can result in:

Sashes that do not slide smoothly.

holes in the frame that allow water causing damage and decay.

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

In the I920s and I930s steel casement windows grew in popularity because they were strong, slim and cheap and also matched the fashion for healthy living. However, research has revealed that traditional softwood sash windows are as efficient thermally as double-glazed windows made of PVC-u, and may be more appealing than the sleek lines of modern casement windows.

The industry of replacement windows has made a significant effort to persuade house owners that their windows are rotten, draughty and beyond repair. However, many older windows made of wood are in good shape and with minor repairs can easily be repaired for many years to be.

5. Maintenance

If you fail to maintain your sash window and door repair near me, it could cause the sash cords breaking, and the glazing bars wearing out excessively. It could also cause paint and putty to degrade. The removal of sashes can also cause structural movement in the frame, causing the sash to not close properly. It is also possible for the sash to be stuck or slammed into an open position and let water and draughts in the structure.

Moisture penetration is a common cause of damage to windows made of timber. This can be avoided by regular maintenance as well as thorough painting, and then removing the source of dampness. Wet rot is easily identified due to the wavy appearance of the existing paint which can be stripped to reveal rotting, soft timber. Any rotten timber sections should be cut out and the affected area should be carefully scarfed or pieced in using replacements made from the same kind of timber as the ones that remain. This repair method increases the amount original fabric and is among the most non-invasive methods to treat timber-to-timber rot.

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

It is crucial to restore and not replace any historical ironmongery such as the sash latches and stays. These items are difficult to replace without compromising the quality of the original design. It is also recommended that modern fittings made of aluminium like sashlifts, as well as chainstays, should be avoided since they can cause deterioration and corrosion of timber frames and sashes.
