How to Restore Timber Sash Windows in Cambridge
Many homes in Cambridge have traditional sash windows and homeowners are proud of how they look. Sash windows can get stuck and become difficult to open or shut. This is often due to moisture which can cause the timber to expand.
Traditionally, window boxes utilised chains, cotton cords or weights made of lead to operate. Modern sash windows feature hidden springs to solve this problem.
1. Aesthetics
Timber sash windows, unlike PVC-u windows, which are made in imperial sizes, which are modular, can be restored to their original dimensions. This allows the restoration of timber sash windows to meet the current energy requirements and to comply with conservation regulations for areas. It also offers a window with a far superior appearance than the

Sliding sash windows were originally only used in large buildings or public buildings, but the production process became less expensive and craftsmen could produce larger frames with more glass. In the 18th century, sash windows were the dominant design of wood in the majority of British properties. Sash windows were simple to operate and let light into rooms without the need for curtains.
The early windows were made of glass that was plain however, by the 17th Century sash windows started to become more attractive. They started with coloured glazing bars or mullions. They were expensive at first, but when glass production became less expensive and more efficient, they became an integral feature in many period houses.
In the 19th century, it was possible to make large, sturdy glasses that didn't require support bars. This allowed the frame's size to be enlarged more, which in turn gave a better view from the window. This was a significant advancement.
Another significant improvement was the introduction of the double-hung sliding window at the end of the I920s and beginning of the I930s. The double-hung sliding sash was a important improvement that came into existence at the end of the I920s and beginning of the I930s.
Oak was used for older examples and for more prestigious buildings. It is crucial to maintain the parting bead which is used to separate the sashes. This will help prevent rattles and draughts. The idler wheels, sash pulleys and sash rollers also are vital for the proper operation of the window.
2. Energy efficiency
As larger and clearer sheets of
glass repair cambridge became available, sash window started replacing hinged casements. They were glazed with plate glass placed within timber frames with rebates and secured with glazing sprigs and putty on both sides to create a watertight seal. This type of glass gradually replaced leaded lights.
The introduction of sashes created an need for a wider range of ironmongery, including the most basic fittings, brass pulleys as well as lead (and later cast iron) weights, sash stoppers shutter hinges and knobs, and a range of fasteners to hold the sashes into place. They were often decorated with motifs, inscriptions, and designs that were engraved to identify the maker.
Sash windows are energy efficient if they are maintained regularly. Without this maintenance they could become noisy. Draughts can also result from the degeneration of putty and paint. This can be fixed by making use of wood-to-timber repair tools that are proprietary.
The replacement window industry relies heavily on the belief that old windows are beyond repair and are not able to be maintained economically. However they can be maintained with a little attention. However, repairs to these windows are costly and can cause substantial disruption to the home. Many homeowners opt to replace their windows with PVC-u from a large "one-stop shop" installation company. They can replace all windows in a house in one day, thereby saving time and avoiding the need for various tradesmen to coordinate. They can also be supplied with 'energy saving'
double glazed door repairs-glazing, which can achieve greater energy efficiency than are possible with traditional sash windows. However, these double-glazed units cannot replicate the section and proportions of traditional timber sashes.
3. Security
Traditional windows can be made secure without compromising their appearance. Ironmongery like mortice bolts, sash chain and sash lock could be used. These can be installed in a way that the window remains open to allow ventilation or for cleaning. They are generally unobtrusive, as they are designed to fit the sash window. They can be used in conjunction with traditional sash-window catchers and must be replaced by more robust models (such as those incorporating double screws) or spring levers to decrease the chance of them being hammered out.
Sash-window frames were typically constructed from slow-growing deal or, in more elegant homes they were made from oak. Where glazing bars have survived they should be kept, and where feasible, the wood of the cill should be replaced by identical wood. Many PVC-U firms provide a one-stop shop installation service. They can take down and replace windows on an entire house in just one day, without involving any other tradespeople.
4. Ventilation
Sash windows were introduced in the 17th Century and allowed for a large amount of light into buildings. By the end of the 18th century they were altered to allow even more light into rooms, and bigger glazing panes started to be produced. The result was a much more streamlined appearance, and windows with a higher quality of design than before.
Sash windows were introduced and required a new type of ironmongery. Early pulleys were made from wood, while later Victorian ones could be made of brass or a mixture of lead and wood, and there were a variety of shutter hinges and knobs. These ironmongery pieces should be maintained and cleaned to appreciate their beautiful design.
To ensure they remain in good condition, timber windows require regular maintenance. Lack of attention to them regularly can lead to:
Sashes that do not slide easily.
Holes in the frame which allow water to enter and cause damage and decay.
The putty can be soaked by water and cause decay to the frame or cause cill.
In the I920s and the I930s steel casement windows increased in popularity because they were strong slim and inexpensive, and complemented the vogue for healthy living. However, research has proven that traditional softwood sash windows can be just as efficient in thermal efficiency as double-glazed PVC-u windows and are more attractive than the modern sleek design of casement windows.
The window replacement industry has done a great job convincing homeowners that their old windows were decayed, drafty and beyond economical repair. The truth is that a lot of old windows made of timber are in good shape and with minor repairs can easily be serviceable for many years to be.
5. Maintenance
A traditional sash window needs regular maintenance and inspection. If you fail to maintain your sash window, it can cause the sash cords breaking, and the glazing bars wearing out excessively. It can also cause the paint and putty to deteriorate. The removal of sashes may also cause structural movement in the frame, which can cause the sash not to close properly. The sash can also be stuck in the open position, which allows water and draughts to enter the building.
Moisture penetration is the most common cause of damage to windows made of timber. This can be prevented by regular repairs as well as thorough painting, and then removing the cause of dampness. The paint can be removed to expose the soft, decaying wood. Any rotten sections of timber should be cut off and the affected area should be carefully wrapped or pieced back using replacements made from the same type of timber as those remaining. This method of
upvc door repair increases the amount of original fabric retained and is among the least invasive methods for treating decay of timber to timber.
The use of a wood consolidant made from resin is another alternative to the traditional method of sanding and staining. This is brushed onto the surface of the wood to help stabilize it and shield it from further damage. It is particularly useful for the treatment of pulleys and sash cords which help prevent the breakage.
It is essential to preserve and not replace any historical ironmongery, such as the sash latches and stays. It is difficult to replace these items without altering their original design. It is also recommended that modern Aluminium Casement Windows
cambridge double glazing (
