How to Restore Timber Sash Windows in Cambridge
Many homes in Cambridge have sash windows that are traditional and homeowners are proud of the way they appear. However, sash windows can get stuck and be difficult to open or close. This is often due moisture that can cause the timber to swell.
Traditionally, windows made of box sash utilized chains, cotton cords or lead weights to operate. Modern sash windows feature hidden springs to overcome this problem.
1. Aesthetics
Timber sash windows, unlike PVC-u windows that are made in imperial sizes and are modular, can be reconstructed to original dimensions. This allows the restoration of timber sash windows to comply with current energy standards and comply with conservation regulations for areas. It also provides a window with a far more attractive appearance than emergency upvc door repairs (www.i-hire.ca) alternatives.
Sliding windows with sash were initially intended for large structures or public buildings. However this changed as production became cheaper and artisans could create larger frames using greater glass. At the close of the 18th century, sash windows were the most popular wooden style in British homes. Sash windows were easy to operate and let light into rooms without the need for curtains.
The first windows were made of plain glass but by the 17th century, sash windows started to become more attractive with coloured glass bars and moulded mullions. These were very expensive at the time but as glass production became more efficient and less expensive, they were a common feature in numerous period houses.
In the 19th century, it was possible to create large, strong glasses that did not require support bars. This allowed the frame to be made larger, which in turn gave a better view. This was a significant innovation.
The introduction of the double-hung sliding sash was a significant improvement that came about at the end of the I920s and beginning of the I930s. The double glazing repairs-hung sliding sash is another important improvement that was made at the end of the I920s, and at the beginning of the I930s.
The most popular type of sash is made of slow-growing deal (pine) but oak was used in the more luxurious buildings and in earlier examples. A parting bead separates the two sashes and it is essential that it is well maintained to prevent rattles and drafts. It is also essential that sash pulleys and idler wheels are in good working order as they assist in operating the window.
2. Energy efficiency
Sash windows replaced hinged cases as larger and clearer sheets were made available. They were made of plate glass, set in timber frames with rebates and secured with glazing sprigs, and then putty on both sides to make them watertight. This kind of glazing gradually superseded leaded lights.
Sashes were introduced, which resulted in increased demand for ironmongery. The most common fittings included brass pulleys (and later cast-iron) weights, sash stoppers, shutter hinges and handles and a variety of fasteners used to fix the sashes. They were often decorated with motifs, inscriptions and engraved patterns that identified the maker.
Sash windows are energy-efficient with regular maintenance. If they are not maintained they can get draughty. Putty and paint can cause draughts too. This issue can be fixed 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 cannot be maintained economically. However, they can easily be maintained with a bit of attention. These repairs can be expensive and cause a lot of disruption in the home. To avoid this homeowners often opt for a complete replacement with PVC-u windows made by one of the many 'one stop shop' installation companies. They can take down and replace all windows in a house in just one day, avoiding the need to coordinate multiple tradesmen and making the entire process much more efficient. These windows can be fitted with energy-saving double glazing to get more energy efficient ratings than a traditional sash window. However these double-glazed units are unable to duplicate the proportions and section of historic timber sashes.
3. Security
It is possible to secure traditional windows without compromising on their aesthetics. Ironmongery like mortice bolts, sash chain and sash locks can be installed. These can be installed in a manner that the window can be opened for ventilation and cleaning. These windows are typically discrete since they are made to work with sash windows. They can be used in conjunction with traditional sash-window catchers, which must be replaced by more robust models (such ones with double screws) or spring-loaded levers to minimize the chance of them being hammered open.
Sash-window frames were traditionally made from slow-growing deal or, in more elegant homes, from oak. Where glazing bars have survived they should be kept, and if it is possible, the timber of the cill should be replaced with the same wood. Many PVC-U firms provide a one-stop shop installation service. They can remove and replace windows on a complete home in one day, without involving other tradespeople.
4. Ventilation
When sash windows first introduced in the 17th century they allowed a significant amount of light to flood into buildings. In the 18th century, they were modified to allow more light could be let into rooms. Larger glass panes were also produced. The result was a more light appearance and windows with more elegance.
The introduction of sash windows also necessitated an entirely new range of ironmongery. Early pulleys were made out of wood. Later Victorian ones were made of brass or a mix of leaded and wood. There were also a variety of types of knobs and shutter hinges. Ironmongery elements must be maintained and cleaned so that the quality of their design can be appreciated.
Timber windows require careful maintenance to ensure they remain in good condition. A lack of regular attention can result in:
Sashes that do not slide easily.
holes in the frame allow water causing damage and decay.
Water can get into the putty and cause decay to the frame or cause cill.
Steel casement windows became popular in the I920s & I930s due to their strength and slim, cheap and matched the trend towards healthy living. However, research has shown 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 sleek lines of modern casement windows.
The replacement window industry has done a lot to persuade house owners that their traditional windows are rotten, draughty and beyond repair. Many old windows made of timber can be repaired and used for a long time with minor repairs.
5. Maintenance
A traditional sash window needs 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 may also result in structural movements within the frame, which can cause the sash not to close correctly. The sash can also be stuck in an open position, which allows water and draughts into the property.
Moisture penetration is a common cause of damage to windows made of timber. This can be prevented by regular repairs by thorough painting and eliminating the cause of dampness. The paint can be removed to expose the soft, rotting wood. Any rotten sections of timber must be removed and the affected area should be carefully wrapped or pieced back using replacements made of the same type of timber as those remaining. This method of repair maximizes the amount of fabric used in the first place and is one of most non-invasive methods to treat the rot that occurs between timber and timber.
The use of a resin-based wood consolidant is a different option to the traditional method of sanding and staining. This is brushed onto the surface of the timber to stabilize it and shield it from further damage. It is particularly useful for treating pulley cords and sash which can stop breakage.
It is crucial to restore and not replace any historic ironmongery such as the sash latches and stays. It can be difficult to replace these items without altering their original design. It is also recommended that fittings made of aluminum, such as sashlifts and chainstays, be avoided as they can cause deterioration and corrosion of timber frames and sashes.
