1. Aesthetics

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

Sliding frames for windows made of sash were originally only used in large buildings or public buildings. However the production became cheaper and artisans could make larger frames using larger glass. At the end of the 18th century, sash windows were the most sought-after wooden style in British homes. Sash windows were simple to operate and let light into rooms without the need for curtains.

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

In the 19th century, it was possible to create large, strong glasses 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 very important improvement.

The introduction of the double-hung sliding sash was another important improvement that occurred towards the end of the I920s and the beginning of the I930s. This allowed both the upper and lower sash to be opened simultaneously, and also improved the ventilation of buildings.

The most common type of sash is constructed of slow-growing deal (pine) however oak was also used in more luxurious buildings and in earlier examples. It is essential to keep the separation bead that divides the sashes. This will prevent draughts and rattles. The sash pulleys, idler wheels and sash rollers also are crucial for the proper operation of the window seal repairs - menwiki.men -.

2. Energy efficiency

Sash windows replaced hinged casements as clearer and larger sheets became available. They were coated with plate glass that was set in timber frames with rebates and then pinned with glazing sprigs, and then putty on both sides to make them watertight. This type of glazing gradually replaced the leaded light bulbs.

The introduction of sashes created the need for a larger variety of ironmongery including the most basic fittings, brass pulleys and lead (and later cast iron) weights, sash stops shutter hinges and knobs, and a range of fasteners used to keep the sashes to their place. They were often decorated with motifs, inscriptions or engravings that identified the maker.

Sash windows are energy efficient when they are maintained regularly. Without this maintenance they can get draughty. Paint and putty can cause draughts too. This issue can be fixed by using wood-to-timber solutions.

The market for replacement windows rests on the assumption that older windows are old and beyond repair, but they can be easily maintained with a little attention. Repairs can be expensive and cause a lot of disruption in the home. To avoid this homeowners, many 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 avoiding the need for various tradesmen to coordinate. They can also be supplied with 'energy saving' double-glazing, which can achieve greater energy efficiency than 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. A variety of ironmongery types can be installed with sash chains, mortice bolts, and sash locks. They can be fitted so that the window is still able to be opened for ventilation or for cleaning. They are generally not noticeable, since they are designed to complement the sash window. They can be utilized in conjunction with traditional sash-window catchers that must be replaced by more robust models (such ones with double screws) or sprung levers to reduce the chance of them being opened by hammering.

Sash-window frames were constructed from slow grown deal or, in the more elegant homes they were made from oak. If the glazing bars remain in good condition and in good condition, they should be kept. Where it is possible, the cills of the timber should be replaced with wood that matches. Many PVC-U firms offer a one-stop installation service. They can remove and replace windows throughout a home in one day, without involving other tradespeople.

4. Ventilation

Sash windows were introduced in the 17th century and allowed for a large amount of light into buildings. At the end of the 18th century, they had been modified so that more light could be let into rooms. Larger glazing panes were also produced. The result was a much more streamlined appearance, and windows with a greater quality of design than before.

The introduction of sash windows also necessitated an entirely new range of ironmongery. Early pulleys could be 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 knobs and shutter hinges. These ironmongery pieces should be kept clean and preserved in order to appreciate their exquisite design.

To ensure they remain in good condition, wooden windows need to be maintained. Inattention to maintenance can lead to:

Sashes that no longer slide easily.

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

break down of the putty and allow water to penetrate, which could lead to decay of the frame and cill.

In the I920s and the I930s steel casement windows increased in popularity because they were strong slim and inexpensive and were in line with the trend for healthy living. Research has proven that softwood sash windows are just as effective as PVC-u windows, and may even be more attractive.

The industry of replacement windows has done a lot to persuade house owners that their old windows are dirty, noisy and beyond repair. Many older timber windows are repairable and can be used for many more years with minor repairs.

5. Maintenance

A traditional sash window needs regular maintenance and inspection. If you do not maintain your sash window, it can cause the sash cords breaking and the glazing bars wearing out excessively. It could also cause paint and putty to deteriorate. The removal of the sashes can also result in structural movement within the frame which causes the sash to become misaligned and in a position that it is not able to close properly. The sash can also be stuck in its open position, which allows water and draughts into the building.

The damage to timber windows is often caused by water entry. This can be prevented by careful painting, regular repairs and elimination of the cause of dampness. Wet rot is recognisable due to the wavy appearance of the paint, which can be removed to reveal soft, rotting wood. Any rotten sections of timber should be cut off and the affected area carefully cut or pieced with replacements made from the same kind of timber as those remaining. This method of repair increases the amount of fabric left, and is one of the least invasive ways of treating decay of timber to timber.

A wood condenser that is based on resin is a viable alternative to traditional sanding or staining. The product is brushed on to the surface of the timber to stabilize it and shield it from further damage. It is particularly useful for the treatment of sash cords and pulleys which can help prevent breakage.

It is essential that any old ironmongery such as sash stays and latches are retained and rehabilitated instead of being replaced. These items can be very difficult to replace without harming the quality of the original design. It is also advised that modern fittings made of aluminium like sashlifts and chainstays, are avoided since they could cause corrosion and deterioration of timber frames and sashes.
