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 can get stuck and be difficult to open or close. This is typically due to moisture which can cause the wood to expand.
Traditionally, windows made of box sash used chains, cotton cords or lead weights to operate. Modern window springs for sash windows are concealed to solve this problem.
1. Aesthetics
Timber sash windows, in contrast to PVC-u windows which are manufactured in imperial sizes that are modular, can be reconstructed to their original dimensions. This allows the restoration of timber sash windows in order to meet the current energy requirements and to comply with conservation regulations for areas. It also offers windows that have a more attractive appearance than upvc window renovation alternatives.
Sliding sash window frames were initially intended for large structures or public buildings. However this changed as production became cheaper and artisans could create larger frames using more glass. At the close of the 18th century, sash windows were the most sought-after wooden style in British homes. Sash windows were easy to operate and let light into rooms without the use of curtains.
Early windows were simple glass but by the 17th century sash windows started to become more decorative with coloured glazing bars and moulded mullions. They were costly at the beginning but as glass production became cheaper and more efficient, they became a common feature in many historic homes.
In the 19th century, it became possible to create large, sturdy glasses that did not require supporting bars. This allowed for the frame to be enlarged which, in turn, provided a better view. This was a significant innovation.
Another important improvement was the introduction of the double-hung sliding window at the end of I920s and at the beginning of I930s. This allowed both the upper and lower sash to be opened simultaneously and also improved the ventilation of buildings.
Oak was used in older examples and more prestigious buildings. It is important to maintain the separation bead that is used to separate the sashes. This will prevent draughts and rattles. The sash pulleys, idler wheels and sash rollers are essential to the operation of the window.
2. Energy efficiency
Sash windows were replaced by hinged casements as larger and clearer sheets became available. They were made of plate glass, set in timber frames with rebates and then pinned with glazing sprigs and putty on both sides to make them watertight. This form of glass gradually replaced the leaded light bulbs.
The introduction of sashes resulted in an need for a larger variety of ironmongery with the most basic fittings being brass pulleys and lead (and later cast iron) weights, sash stoppers shutter hinges and knobs, and a range of fasteners that secured the sashes in the right place. These were often decorated with motifs, inscriptions, and engravings that identified the maker.
With regular maintenance, sash windows are very energy efficient. However, without this maintenance they can become drafty and let in cold air. Draughts can also be caused by the deterioration of putty and paint. This can be corrected using proprietary wood-to-timber repair products.
The market for replacement windows is based heavily on the perception that old windows are beyond repair and therefore cannot be maintained economically. However they can be maintained with a little attention. However, repairs to these windows can be expensive and involve substantial disruption to the home. Many homeowners decide to replace their windows using PVC-u from a huge "one-stop shop" installation company. They can replace and remove all the windows in an entire house within a single day, avoiding the need to co-ordinate different tradesmen and making the whole process much quicker. These windows can be fitted with energy-saving' double glazing to achieve higher energy ratings than the traditional windows with sash. However, these double-glazed units cannot duplicate the proportions and section of the sashes made of timber from the past.
3. Security
It is possible to secure windows that are traditional without compromising their style. Ironmongery like mortice bolts, sash chain, and sash lock can be used. These can be put in place so that the window remains open for ventilation or for cleaning. They are generally minimal in appearance, as they are designed to fit the sash window. They can be used in conjunction with traditional sash-window catches, which should be replaced with more robust models (such as those incorporating double screws) or sprung levers to reduce the risk of them being hammered out.
Sash-window frames are typically made of 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 with identical wood. Many PVC-U firms offer a one-stop shop installation service. They can remove and replace windows throughout a home in a single day, without involving any other tradespeople.
4. Ventilation
When sash windows first introduced in the 17th century they allowed a large amount of light into buildings. At the end of the 18th century, they were modified so that more light could be let into rooms. Larger glazing panes were also created. The result was a lighter appearance and windows with more elegance.
The introduction of sash windows also necessitated an entirely new range of ironmongery. Early pulleys were of wood, whereas later Victorian ones were made of brass or a mixture of wood and lead, and there were various types of shutter hinges and knobs. These ironmongery pieces should be maintained and cleaned to appreciate their beautiful design.
Timber windows require regular maintenance to ensure they remain in good condition. Inattention to maintenance can result in:
Sashes that don't slide effortlessly.
holes in the frame that admit water that can cause decay and damage.
break down of putty allowing water to penetrate, which can lead to decay in the frame and cill.
Steel casement windows became popular in the I920s and I930s because they were strong and slim, cost-effective and complemented the trend for healthy living. Studies have shown that softwood sash window are just as effective as PVC-u windows, and may even be more attractive.
The industry of replacement windows has made a significant effort to convince homeowners that their traditional windows are dirty, noisy and beyond economic repair. Many old windows made of timber are repairable and can be used for many more years with minor repairs.
5. Maintenance
A traditional sash window needs regular maintenance and inspection. If you do not maintain your sash window, it could lead to the sash cords breaking and the glazing bars deteriorating excessively. It could also cause paint and putty degrade. The removal of the sashes could also result in structural movement within the frame that causes the sash to be misaligned and in a position that it is not able to close properly. It is also possible for the sash to be snagged or fixed in the open position, which can let water and draughts into the structure.
Moisture penetration is a frequent cause of damage to windows made of timber. This can be prevented by careful painting, regular upvc door handle repairs near me and the elimination of the cause of dampness. Wet rot is easily identified due to the wavy appearance of the existing paint which can be removed to reveal rotting, soft timber. Any timber that is rotting should be cut out and the affected area should be carefully wrapped or pieced back using replacements made from the same kind of timber as the ones that remain. This method of repair increases the amount of original fabric left, and is one of the least invasive methods for treating decay caused by timber.
The use of a resin-based wood consolidant is an alternative to traditional staining and sanding. This is brushed on the surface of the wood to protect it and stabilise it. It is particularly useful for the treatment of sash cords and pulleys which can help prevent breakage.
It is essential to preserve and not replace any historical ironmongery, such as sash latches and stays. They can be extremely difficult to replace without damaging the the original design. It is also recommended that the use of modern aluminum fittings like sash lifts and chain stays is avoided whenever possible as they can cause corrosion and deterioration of frames and sashes made from timber.
