How to Restore Timber Sash Windows in Cambridge
Many homes in Cambridge have traditional sash windows and the homeowners are proud of their appearance. However, sash windows can get stuck and be difficult to open or close. This is usually due moisture that can cause the wood to expand.
Box sash windows were traditionally operated with chains or cotton cords, as well as weights made of lead. Modern sash window springs are hidden to avoid this issue.
1. Aesthetics
Contrary to PVC-u windows which are manufactured to modular imperial sizes Timber sash windows can be restored to their original sizes. This allows for the restoration of timber sash windows in order to comply with current energy standards and to comply with conservation area regulations. It also comes with windows that are superior to uPVC alternatives.
wooden sliding doors cambridge sash window frames were initially intended for large structures or public buildings. However this changed as production became less expensive and craftsmen could create larger frames using larger glass. By the late 18th century sash windows were the dominant design of wood in the majority of British properties. Sash windows were easy to operate and let light in rooms without the need for curtains.
The first windows were made of plain glass However, by the 17th Century sash windows started to become more ornamental. They began with colored glazing bars, also known as mullions. They were expensive at first, but when
glass repair cambridge production became less expensive and more efficient, they were a common feature in many homes of the period.
In the 19th century, it became possible to produce large, sturdy glasses that didn't require supporting bars. This allowed the frame to be made bigger which, in turn, provided a better view. This was a very important advancement.
Another important improvement was the introduction of the double-hung sliding window at the end of the I920s and beginning of I930s. The double glazed door repairs,

The most commonly used type of sash is made of slow-growing deal (pine) but oak was used in the more luxurious buildings and in earlier examples. It is crucial to maintain the parting bead which is used to separate the sashes. This will prevent draughts and rattles. It is also essential that the idler and sash pulley wheels are in good condition as these aid in operating the

2. Energy efficiency
As larger and clearer sheets of glass were made available, sash windows started replacing hinged casements. Plate glass was placed in frames of timber that were rebated, then pinned with glazing sprigs and putty was applied to the frame's two sides for watertightness. This type of glazing gradually superseded led lights.
The introduction of sashes created the need for a larger variety of ironmongery with the most basic fittings being brass pulleys, lead (and later cast iron) weights, sash stoppers shutter hinges, knobs and shutters and a variety of fasteners used to keep the sashes in place. They were often decorated with motifs, inscriptions or engravings that identified the maker.
Sash windows can be very energy-efficient with regular maintenance. Without this maintenance, they can become drafty. Draughts can also be caused by the deterioration of paint and putty. It is possible to fix this issue by using wood-to-timber solutions.
The market for replacement windows is based heavily on the belief that old windows are damaged beyond repair and are not able to be maintained economically. However, they can easily be maintained with a bit of attention. However, these repairs are costly and can cause considerable disruption to the home. Many homeowners opt to replace their windows using PVC-u from a huge "one-stop shop" company for installation. These can remove and replace all the windows in a home within a single day, eliminating the need to coordinate multiple tradesmen, making the whole process much more efficient. They can also be supplied with 'energy saving' double-glazing to achieve more energy efficient ratings than traditional windows made of sash. These double-glazed windows aren't 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 style. Ironmongery such as mortice bolts, sash chain and sash lock could be put in place. They can be positioned in such a way that the window can still be open for ventilation and cleaning. These products are often not noticeable since they are designed to complement sash windows. They can be used with traditional sash window catch. They should be replaced with more robust models, such as those with double screws, or sprung levers to decrease the risk of being hit with hammers.
Sash-window frames are traditionally made from oak or slow-grown deal. If glazing bars have survived, they should be kept, and, if it is possible, the timber of the cill should be replaced by identical wood. PVC-u companies often offer a one stop shop installation service that can remove and replacing windows on a complete home in a single day without the need to involve other tradespeople or co-ordinate various visits from a number of different suppliers.

By the end of the 18th century they were altered to allow more light into rooms and larger glass panes began to be made. The result was a more streamlined appearance, and windows with a higher quality of design than before.
The introduction of sash windows also necessitated the creation of a new line of ironmongery. Early pulleys could be made out of wood. Later Victorian ones were made of brass or a combination of leaded and wood. There were also different types of shutter hinges and knobs. Ironmongery elements must be kept and cleaned so that the quality of their design can be appreciated.
Timber windows require regular maintenance to keep them in good order. Lack of regular attention may cause:
Sashes that don't slide effortlessly.
holes in the frame that allow 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.
Steel casement windows became popular in the I920s and I930s due to their strength and slim, cost-effective and matched the trend towards healthy living. Research has proven that softwood sash windows are just as effective as PVC-u windows and can even be more attractive.
The replacement window industry was able to convince homeowners that their old windows were decayed, drafty and beyond economical repair. However, many older 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 requires regular maintenance and inspection. Failure to do this can lead to the sash cords breaking, a lot of wear on the glazing bars and the deterioration of putty and paint. The removal of the sashes could also result in structural movement within the frame which causes the sash to be misaligned and not closing properly. It is also possible for the sash to be stuck or slammed into an open position and let water and draughts into the structure.
Moisture penetration is a frequent cause of damage to windows made of timber. This can be avoided by thorough painting, periodic repairs and elimination of the source of dampness. Wet rot is recognisable by the wavy appearance of the paint, which can be stripped away to reveal soft, rotting wood. The sections that are rotting must be removed with care, and the affected area should be scarfed together or glued together with replacements of the exact kind as the timber that remains. This method of repair increases the amount of fabric retained and is one of the least invasive ways of treating decay of timber to timber.
A resin-based wood condenser is an alternative to the traditional process of sanding or staining. It is brushed on the surface of the timber to help stabilize it and shield it from further damage. It is particularly useful to treat sash and pulley cords, which can help prevent breakage.
It is important to restore and not replace any historic ironmongery, like the 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 like chain stays and sash lifts should be avoided if possible since they can cause corrosion and deterioration to frames and sashes made of timber.
