5 Things Everyone Gets Wrong About Sash Windows Cambridge

How to Restore Timber Sash Windows in Cambridge

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 usually due to moisture, which can cause the timber to expand.

Traditionally, window boxes utilised chains or cotton cord and weights made of lead to operate. Modern window springs for sash windows are concealed to solve this problem.

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 to meet current energy requirements and comply with conservation regulations for areas. It also provides windows with a superior appearance than the upvc window renovation (www.stes.Tyc.edu.tw) alternatives.

Sliding sash windows were initially only found in large buildings or public buildings, though the production process was less expensive and craftsmen were able to create larger frames using more glass. At the end of the 18th century, sash windows had become the most popular wooden design in British homes. Sash windows were simple to operate and let light into rooms without the use of curtains.

The first windows were made of clear glass However, in the 17th century, sash windows began to become more ornamental. They began with colored glazing bars or mullions. These windows were quite expensive at the time but as glass production improved and cheaper they became a part of many period houses.

In the 19th century, it became possible to create large, sturdy glasses that did not require support bars. This allowed the frame size to increase further, which gave a better view from the window. This was a significant advancement.

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

Oak was used for older and more luxurious buildings. It is important to maintain the parting bead that divides the sashes. This will help prevent rattles and draughts. It is also essential that sash pulleys and idler wheels are kept in good shape as they aid in operating the window.

2. Energy efficiency

Sash windows were replaced by hinged casements as clearer and larger sheets were made available. They were glazed with plate glass set in timber frames with rebates and pinned in place using glazing sprigs, and then putty on both sides to create a watertight seal. This type of glazing gradually replaced leaded lights.

The introduction of sashes resulted in a need for a much wider range of ironmongery, with the basic fittings being brass pulleys and lead (and later cast iron) weights, sash stops, shutter hinges and knobs as well as a range of fasteners used to keep the sashes in the right place. These were often decorated with motifs, inscriptions or designs that were engraved to identify the maker.

With regular maintenance, sash windows are extremely energy efficient. Without this maintenance they could become draughty. Paint and putty may cause draughts. This can be remedied by using wood-to-timber repair products that are specifically designed for this purpose.

The market for replacement windows rests on the perception that old windows are damaged and beyond repair, but they can be maintained with a bit of care. Repairs can be costly and cause a lot of disruption in the home. To prevent this homeowners, many opt for a complete replacement with PVC-u windows from one of the largest 'one stop shop' installation companies. They can replace all windows in a home in one day, thereby saving time and avoiding the need for various tradesmen to coordinate. They are also available with energy-saving double-glazing to achieve higher energy efficiency ratings than those offered by traditional windows with sash. These double-glazed units are not capable of replicating the proportions or section of the sashes made of timber from the past.

3. Security

It is possible to secure traditional windows without compromising on their aesthetics. Many types of ironmongery are available including sash chains mortice bolts, and locks for sash. They can be fitted in such a way that the window can be opened for ventilation and cleaning. These windows are typically not noticeable since they are designed to complement sash windows. They can be used alongside traditional sash-window catchers that are required to be replaced with more robust models (such ones with double screws) or spring levers to decrease the possibility of them being hammered out.

Sash-window frames were typically constructed from slow grown deal or, in the more elegant homes they were made from oak. When glazing bars have survived they should be preserved, and, if possible, the timber of the cill should be replaced by identical wood. Many PVC-U companies offer a one-stop installation service. They can take out and replace windows on a complete house in just one day, without the need to involve other tradespeople.

4. Ventilation

Sash windows were introduced in the 17th Century and allowed for a huge amount of light to enter buildings. By the end 18th century, they were modified so that more light could be let into rooms. Larger glazing panes were also made. The result was a much lighter appearance, and windows with a higher degree of elegance 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 combination of wood and leaded. There were also various kinds of knobs and shutter hinges. These ironmongery elements should always be retained and cleaned down so that the quality of their design can be appreciated.

timber double glazed windows cambridge windows require regular maintenance to keep them in good shape. Inattention to maintenance can result in:

Sashes that don't slide easily.

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

The putty can be soaked by water and cause decay to the frame or cause cill.

Steel casement windows gained popularity in the I920s & I930s because they were strong and slim, and also because they were cheap and complemented the trend for healthy living. However, research has revealed that traditional softwood sash windows can be just as thermally efficient as double-glazed windows made of PVC-u, and are more attractive than the modern sleek design of casement windows.

The industry of replacement windows has made a significant effort to persuade house owners that their traditional windows are rotten, draughty and beyond repair. Many old windows made of timber are repairable and can be used for a long time with minor repairs.

5. Maintenance

A traditional sash window requires regular maintenance and inspection. Inability to keep up with this could result in broken sash cords, excessive wear on the glazing bars and deterioration of paint and putty. The removal of sashes can also result in structural movements within the frame, which can cause the sash not to close correctly. It is also possible for the sash be stuck or slammed into an open position, which can let water and draughts enter the property.

Moisture penetration is a common cause of damage to timber windows. This can be prevented with thorough painting, periodic repairs and the elimination of the cause of dampness. The paint can be removed to expose the soft, rotting wood. The sections that are rotting must be removed with care, and the affected area should be snared together or glued together with replacements of the exact nature as the rest of the timber. This repair method increases the amount of fabric that was originally used and is among the most minimally invasive methods of treating wood-to-timber rot.

The use of a resin-based wood consolidant is another alternative to the traditional method of sanding and staining. The product is brushed on to the surface of the wood to stabilise and protect it from further damage. It is especially beneficial for treating pulley cords and sash, where it can prevent breakage.

It is important that any ironmongery from the past such as sash stays and latches are kept and rehabilitated instead of being replaced. It can be difficult to replace these items without altering their original design. It is also recommended that modern aluminium fittings, such as sashlifts and chainstays, be avoided as they can cause deterioration and corrosion of timber frames and sashes.
