1. Aesthetics
In contrast to PVC-u windows, which are constructed according to imperial sizes that are modular the timber sash windows are able to be restored to their original size. This permits the re-installation of timber sash windows to meet the current energy requirements and conform to conservation area regulations. It also comes with a window installation cambridge that is far superior to upvc repairs options.
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 greater glass. In the 18th century, sash windows were the dominant wooden design in most British homes. Sash windows were simple to operate and allowed light to enter rooms without the need for curtains.
The early windows were made of clear glass, but by the 17th Century sash windows started to be more decorative. They were initially made of colored glazing bars or mullions. They were expensive at the beginning but when glass production became less expensive and more efficient, they were commonplace in many period houses.
By the 19th century it was possible to make large, strong glass that did not require supporting bars. This allowed the frame size to be increased even further, which meant more of a 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 I920s and at the beginning of I930s. The double-hung sliding sash was a significant improvement that came about at the end of the I920s, and at the beginning of the I930s.
Oak was used in older and more luxurious buildings. It is crucial to maintain the parting bead which divides the sashes. This will help prevent draughts and rattles. It is also important that the idler and sash pulley wheels are in good shape as they help to operate the window.
2. Energy efficiency
Sash windows were replaced by hinged casements as clearer and larger 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 create a watertight seal. This type of glass gradually replaced leaded lights.
Sashes were introduced, which resulted in an increase in demand for ironmongery. The basic fittings included brass pulleys (and later cast-iron) weights as well as sash stoppers shutter hinges and handles as well as a variety of fasteners used to fix the sashes. They were often decorated with designs, inscriptions, and patterns engraved to identify the maker.
With regular maintenance, sash windows can be extremely energy efficient. Without this maintenance they could become drafty. Draughts can also be caused by the breakdown of paint and putty. This issue can be fixed by using wood-to-timber products.
The market for replacement windows rests on the perception that older windows are old and beyond economical repair, while they can be easily maintained with just a little care. However, these repairs can be costly and cause considerable disruption to the home. Many homeowners opt to replace their windows using PVC-u from a large “one-stop shop” installation company. They can replace and remove all the windows in a house in a single day, eliminating the need to co-ordinate different tradesmen, making the whole process much faster. They are also available with 'energy saving' double-glazing to achieve greater energy efficiency than traditional windows with sash. However, these double-glazed units cannot duplicate the proportions and section of historic timber sashes.
3. Security
Traditional windows can be made secure without compromising their style. Ironmongery like sash chain, mortice bolts and sash lock could be used. These can be installed in a manner that the window is able to be open for ventilation and cleaning. They are usually discrete since they are made to be used in conjunction with sash windows. They can be used in conjunction with traditional sash window catch. These are best replaced with more robust models, such as those that incorporate double screws, or sprung levers in order to reduce the chance of being hit with hammers.
Sash-window frames are traditionally made of oak or slow-grown deal. If the glazing bars are still in good condition and in good condition, they should be kept. If it is it is possible, the cills of the timber should be replaced by timber that is compatible with. PVC-U companies usually offer a one stop shop installation service, which includes removing and replacing windows on a complete home in a single day without the need to engage other tradespeople or coordinate visits from a number of different suppliers.
4. Ventilation
Sash windows were first introduced in the 17th century and allowed for a huge amount of light to be absorbed into buildings. By the end 18th century, they had been modified to allow more light could be let into rooms. Larger glazing panes were also created. The result was a lighter appearance and windows that were more elegant.
The introduction of sash windows also necessitated an entirely new range of ironmongery. Early pulleys were of wood, later Victorian ones could be made of brass or a combination of lead and wood and there were a variety of shutter hinges and knobs. These ironmongery elements should always be retained and cleaned down so that the quality of their design can be appreciated.
Timber windows require careful maintenance to ensure they remain in good order. Inattention to maintenance could lead to:
Sashes that do not move effortlessly.
Holes in the frame that allow water to enter and cause decay and damage.
The putty can be soaked by water and cause decay to the frame or the cill.
In the I920s and the I930s steel casement windows grew in popularity because they were strong, slim and cheap and also matched the fashion for healthy living. However, research has revealed that traditional softwood sash windows are as efficient thermally as double-glazed PVC-u windows and may be more appealing than the modern sleek design of casement Windows Cambridge.
The replacement window industry has made a significant effort to convince homeowners that their windows are dirty, noisy and beyond economic repair. However, many older windows made of wood are in good condition and, with minor upvc doors repairs, could easily be maintained for years to come.
5. Maintenance
Traditional sash windows require regular maintenance and inspection. If you don't maintain your sash window, it could cause the sash cords breaking, and the glazing bars wearing out excessively. It could also cause paint and putty to deteriorate. The removal of the sashes could also result in structural movement within the frame which 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 and this can let water and draughts into the property.
Damage to timber windows is often caused by moisture infiltration. This can be prevented with careful painting, regular repairs and elimination of the source of dampness. The paint can be removed to expose the soft, rotting wood. The sections of timber that are rotten must be removed with care, and the affected area should be snared together or glued together with replacements of the exact nature as the rest of the timber. This method of repair maximizes the amount of original fabric that is left and is among the least invasive ways of treating decay caused by timber.
The use of a wood consolidant made from resin is another alternative to the traditional method of staining and sanding. It is brushed on the surface of the wood to stabilise and shield it from further damage. It is particularly useful for the treatment of pulley cords and sash, which can help prevent breakage.
It is important to restore and not replace any historic ironmongery, like stay latches and sash latches. These items are difficult to replace without harming the the original design. It is recommended that the use of modern aluminium fittings like sash lifts and chain stays should be avoided if possible since they can cause corrosion and deterioration to frames and sashes made of timber.
