10 Myths Your Boss Is Spreading About Sash Windows Cambridge
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. Sash windows can become stuck and are difficult to open and close. This is usually due moisture that can cause the wood to expand.
Box sash windows were previously operated by chains or cotton cords as well as lead weights. Modern windows with sash springs are concealed to eliminate this issue.
1. Aesthetics
Contrary to PVC-u windows which are manufactured to modular imperial sizes the timber sash windows are able to be restored to their original size. This lets the restoration meet modern day energy requirements while complying with conservation areas regulations. It also comes with windows that are superior to the uPVC options.
Sliding sash window frames were initially only used in large buildings or public buildings. However the production became more affordable and artisans could produce larger frames with more glass. At the end of the 18th century, sash windows had become the most popular wooden style in British homes. Sash windows were simple to operate and let light in rooms without the need for curtains.
The early windows were made of plain glass However, in the 17th century sash windows started to become more attractive. They were initially made of colored glazing bars or mullions. They were expensive at first, but as glass production became less expensive and more efficient, they were an integral feature in many historic homes.
By the 19th century it was possible to make large, sturdy glass that didn't require support bars. This allowed the frame size to be enlarged further and this in turn meant more of a view out of the window. This was a very important innovation.
The introduction of the double-hung sliding sash was a significant improvement that came about towards the end of the I920s and the beginning of the I930s. This allowed both the lower and upper sash to be opened simultaneously and also improved the ventilation of buildings.
Oak was used for older examples and more prestigious buildings. A split bead divides the two sashes and it is important that this is maintained in order to avoid rattles and drafts. The idler wheels, sash pulleys and sash rollers are also vital for the proper operation of the window.
2. Energy efficiency
Sash windows replaced hinged cases as clearer and larger sheets were made available. Plate glass was placed in frames of timber that were rebated, then pinned with glazing sprigs and putty was applied to both sides of the frame for watertightness. This type of glazing gradually replaced the leaded light bulbs.
The introduction of sashes created an need for a wider range of ironmongery, with the most basic fittings being brass pulleys and lead (and later cast iron) weights, sash stops shutter hinges, knobs and shutters and a variety of fasteners that secured the sashes in the right place. upvc windows cambridge were often decorated with designs, inscriptions, and patterns engraved to identify the maker.
With regular maintenance, sash windows are extremely energy efficient. If they are not maintained they could become noisy. Draughts can also be caused by the breakdown of paint and putty. This can be fixed by making use of wood-to-timber repair tools that are proprietary.
The industry of replacement windows relies heavily on the perception that older windows are beyond repair and therefore 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. Many homeowners choose to replace their windows with PVC-u from a 'one-stop shop' installation company. They can replace all windows in a home in a single day, saving time and eliminating the need for various tradesmen to coordinate. They are also available with 'energy-saving' double-glazing, which can achieve greater energy efficiency than those offered by traditional windows made of sash. However double-glazed windows cannot reproduce the proportions and section of historic timber sashes.
3. Security
Traditional windows can be secured without compromising their style. Many types of ironmongery can be fitted including sash chains mortice bolts, and sash locks. They can be positioned in such a way that the window is able to be opened to allow ventilation and cleaning. They are generally minimal in appearance, as they are designed to match the sash window. They can be used in conjunction with traditional sash window catches. These should be replaced with more robust versions like ones that have double screws or spring levers to decrease the chance of being hit with hammers.
Sash-window frames are traditionally made of oak or slow-grown deal. If the glazing bars remain intact and in good condition, they should be kept. If possible, the timber cills should be replaced with timber that is compatible with. PVC-U companies usually offer a one stop shop installation service, removing and replacing windows across a home in one day, without the need to engage other tradespeople or co-ordinate various visits from different suppliers.
4. Ventilation
Sash windows were first introduced in the 17th century and allowed for a huge amount of light into buildings. In the 18th century, they had been adapted so that even 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.
Sash windows were introduced, which required a new range ironmongery. Early pulleys could be made from wood. Later Victorian ones were made of brass or a mixture of wood and lead. There were also different kinds of shutter hinges and knobs. Ironmongery elements must be maintained and cleaned to ensure that the exquisite quality of their design can be appreciated.
Timber windows require regular maintenance to keep them in good shape. Inattention to maintenance routinely could lead to:
Sashes that do not slide smoothly.
holes in the frame that allow water that can cause decay and damage.
Water can get into the putty and cause decay to the frame or the cill.
In the I920s and I930s, steel casement windows increased in popularity due to their durability slim and inexpensive, and complemented the vogue for healthy living. Research has proven that softwood sash window are just as efficient 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 repair. The reality is that many old timber windows are in good condition and with minor repairs can easily be serviceable for many years to come.
5. Maintenance
A traditional sash window requires regular maintenance and inspection. Inability to keep up with this can result in the sash cords breaking, a lot of 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. It is also possible for the sash be snagged or slammed into an open position and this can let water and draughts into the structure.
Damage to timber windows is often caused by water penetration. This can be avoided by careful painting, regular repairs, and removing the source of dampness. The paint can be removed to reveal the soft, decaying wood. The sections of timber that are rotten should be carefully cut out and the affected part should be snared together or pieced together with replacements of the exact nature as the rest of the timber. This repair method increases the amount original fabric and is one of most non-invasive methods to treat timber-to-timber rot.
A wood condenser that is based on resin is an alternative to the traditional process of sanding or staining. The product is brushed on the surface of the wood to protect it and stabilise it. It is especially useful to treat sash and pulley cords, which can help prevent breakage.
It is important to restore and not replace any old 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 is avoided if at all possible as they can cause corrosion and deterioration of frames and sashes made from timber.
