How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge have traditional sash windows and homeowners are proud of the way they look. Sash windows can get stuck and be difficult to open and close. This is usually due to moisture, which can cause the wood to swell.

Box sash windows were historically operated using chains, cotton cords and weights made of lead. Modern sash window springs are hidden to avoid this issue.

1. Aesthetics

Contrary to PVC-u windows which are constructed according to the modular imperial size the timber sash windows are able to be restored to their original dimensions. This permits the re-installation of timber sash windows to comply with current energy standards and to comply with conservation area regulations. It also provides a window that is far superior to the upvc windows cambridge alternatives.

Sliding sash window frames were initially only used for large buildings or public buildings. However, this changed when production became less expensive and craftsmen could make larger frames using greater glass. At the end of the 18th century, sash windows were the most sought-after wooden style in British homes. Since they were easy to open sash windows allowed light into rooms without curtains.

The early windows were made of plain glass, but in the 17th century, sash windows began to become more attractive. They started with coloured glazing bars or mullions. They were expensive initially, but when glass production became less expensive and more efficient, they became commonplace in many historic homes.

In the 19th century, it was possible to make large, sturdy glasses that didn't require support bars. This allowed the frame to be enlarged, which in turn gave a better view. This was a significant improvement.

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

The most common type of sash is made from slow-growing deal (pine) however oak was utilized in more prestigious buildings and in earlier examples. A parting bead is used to separate the two sashes and it is essential that it is maintained to prevent rattles and drafts. The sash pulleys, idler wheels and sash rollers also are essential to the functioning of the Soundproof Window repair.

2. Energy efficiency

Sash windows were replaced by hinged casements as clearer and larger sheets became available. Plate glass was set into rebated timber frames, secured with glazing sprigs and putty was sprayed on both sides of the frame for watertightness. This type of glass gradually replaced the leaded light bulbs.

Sashes were introduced, which led to an increase in demand for ironmongery. The most basic fittings were brass pulleys (and later cast-iron) weights, sash stoppers shutter hinges and handles as well as various fasteners used to fix the sashes. They were often decorated with motifs, inscriptions and engravings that identified the maker.

With regular maintenance, sash windows can be extremely energy efficient. Without this maintenance they can get noisy. Draughts can also result from the degeneration of paint and putty. This can be remedied by using wood-to-timber repair products that are specifically designed for this purpose.

The industry of replacement windows relies heavily on the belief that old windows are damaged beyond repair and cannot be maintained economically. However, they can easily be maintained with a little attention. However, repairs to these windows can be costly and cause significant disruption to your home. To prevent this homeowners, many prefer to replace their windows with PVC-u windows from one of the largest "one stop shop" installation companies. They can replace all windows in a house in one day, thereby saving time and avoiding the need for various tradesmen to coordinate. These windows can be fitted with energy-saving double-glazing to attain higher energy ratings than traditional windows with sash. However double-glazed windows cannot replicate the section and proportions of the sashes made of timber from the past.

3. Security

It is possible to secure traditional windows without compromising their style. Ironmongery like mortice bolts, sash chain and sash locks can be used. They can be fitted so that the window remains capable of being opened for ventilation or cleaning. These products are usually minimal in appearance, as they are designed to complement the sash window seal repairs near me. They can be used in conjunction with traditional sash window catch. They should be replaced by more robust models, such as those with double screws or sprung levers to decrease the chance of being struck by hammers.

Sash-window frames are traditionally made from oak or slow-grown deal. When glazing bars have survived they should be preserved, and, if it is possible, the timber of the cill should be replaced by the same wood. Many PVC-u firms offer a one-stop installation service. They can take out and replace windows throughout a house in just one day, without involving any other tradespeople.

4. Ventilation

When sash windows first introduced in the 17th century they allowed a substantial amount of light into structures. At the end of the 18th century, they were adapted to allow even more light into rooms and larger glazing panes began to be produced. The result was a lighter appearance and windows with a greater quality of design than before.

Sash windows were introduced, which required a new range ironmongery. Early pulleys were constructed out of wood. Later Victorian ones were made of brass or a combination of leaded and wood. There were also different kinds of shutter hinges and knobs. The ironmongery components should be retained and cleaned down to ensure that the exquisite quality of their design can be appreciated.

Timber windows require careful maintenance to ensure they remain in good shape. Lack of attention to them regularly could lead to:

Sashes that no longer slide easily.

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

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

Steel casement windows gained popularity in the I920s and I930s because they were strong and slim, cheap and matched the trend of healthy living. However, research has proven that traditional softwood sash windows can be just as efficient in thermal efficiency as double-glazed windows made of PVC-u, and may be more appealing than the modern sleek design of casement windows.

The industry of replacement windows has done a lot to persuade house owners that their old windows are dirty, noisy and beyond door seal repair near me. The reality is that many older timber windows are in good shape and with minor repairs can easily be repaired for many years to come.

5. Maintenance

A traditional sash window requires regular maintenance and inspection. Failure to do this can result in the sash cords breaking, a lot of 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, causing the sash to not close properly. It is also possible for the sash be snagged or fixed in an open position, which can let water and draughts in the property.

The damage to timber windows is often caused by water infiltration. This can be prevented with careful painting, regular repairs and the elimination of the cause of dampness. Wet rot is recognisable by the wavy look of the existing paint which can be stripped away to reveal soft, rotting timber. The sections that are rotting should be carefully removed and the affected area should be scarfed together or pieced together using replacements of the same nature as the rest of the timber. This method of repair maximizes the amount of original fabric left, and is one of the least invasive methods of treating decay caused by timber.

The use of a resin-based wood consolidant is an alternative to traditional staining and sanding. It is brushed onto the surface of the wood to protect it and strengthen it. It is especially useful for treating pulley cords and sash where it can prevent breakage.

It is important to restore and not replace any historic ironmongery such as sash latches and stays. It is difficult to replace these items without compromising their original design. It is recommended that the use of modern aluminium fittings such as chain stays and sash lifts should be avoided if feasible as they could cause corrosion and damage to timber frames and sashes.
