A Step-By Step Guide To Sash Windows Cambridge
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 may get stuck and be difficult to open or close. This is usually due to moisture, which can cause the timber to swell.
Traditionally, window boxes utilized chains or cotton cord and lead weights to operate. Modern sash window springs are hidden to solve this problem.
1. Aesthetics
Contrary to PVC-u windows which are constructed according to the modular imperial size, timber sash windows can be restored to their original dimensions. This permits the re-installation of timber sash windows to meet current energy requirements and conform to conservation regulations for areas. It also gives windows with a more attractive appearance than uPVC alternatives.
Sliding windows with sash were initially only used in large structures or public buildings, however this changed as production became less expensive and craftsmen could make larger frames with more glass. At the close of the 18th century, sash windows had become the most sought-after wooden style in British homes. As they were easy to open sash windows allowed light into rooms without the need for curtains.
The first windows were made of plain glass but by the 17th century sash windows began to become more decorative, with coloured glazing bars and moulded mullions. They were costly at first, but as glass production became less expensive and more efficient, they were a common feature in many historic homes.
In the 19th century, it was possible to create large, sturdy glasses that didn't need supporting bars. This allowed the frame's size to be increased even further, which allowed for a wider view from the window. This was a significant innovation.
The introduction of the double-hung sliding sash is another important improvement that was made at the end of the I920s and at the beginning of the I930s. The double-hung sliding sash was a important improvement that was made at the end of the I920s, and at the beginning of the I930s.
The most popular kind of sash is made of slow-growing deal (pine) however 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 help prevent draughts and rattles. It is also crucial that sash pulleys and idler wheels are kept in good condition as these help to operate the window.
2. Energy efficiency
Sash windows were replaced by hinged casements as larger and clearer sheets were made available. They were made of plate glass, placed within timber frames with rebates and pinned in place using glazing sprigs and putty on both sides to make them watertight. This kind of glazing gradually replaced the leaded light bulbs.
Sashes were introduced, which led to an increase in 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 can be extremely energy efficient if they are maintained regularly. If they are not maintained they can get noisy. Draughts can also result from the degeneration of paint and putty. This issue can be fixed with wood-to-timber products.
The replacement window industry relies heavily on the perception that old windows are damaged beyond repair and are not able to be maintained economically. However windows can be easily maintained with a bit of attention. However, these repairs are costly and can cause substantial disruption to the home. Many homeowners decide to replace their windows with PVC-u from a large 'one-stop shop' installation company. They can replace all windows in a house in one day, saving time and eliminating the need for multiple tradesmen to coordinate. They can also be supplied with 'energy saving' double-glazing, which can achieve more energy efficient ratings than traditional windows made of sash. However double-glazed windows cannot duplicate the proportions and section of traditional timber sashes.
3. Security
It is possible to secure traditional windows without compromising their appearance. Ironmongery like sash chain, mortice bolts, and sash lock can be used. These can be installed in a manner that the window can be opened to allow ventilation and cleaning. They are usually unobtrusive as they are designed to work with sash windows. They can be used alongside traditional sash-window catches, which should be replaced with more robust models (such ones with double screws) or spring levers to decrease the risk of them being hammered open.
Sash-window frames are typically made from oak or slow-grown deal. Where glazing bars have survived they should be kept, and where it is possible, the timber of the cill should be replaced with the same wood. Many PVC-U firms offer a one-stop installation service. They can take down and replace windows throughout a house in just one day, without involving other tradespeople.
4. Ventilation
Sash windows were introduced in the 17th century and allowed for a significant amount of light into buildings. By the end of the 18th century, they were adapted to allow even more light into rooms, and larger glazing panes began to be made. The result was a much more streamlined appearance, and windows with a higher degree of elegance than before.
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 combination of wood and leaded. There were also different kinds of knobs and shutter hinges. These ironmongery pieces must be kept clean and preserved in order to appreciate their fine design.
To keep them in good condition, wooden windows need to be maintained. Lack of regular attention may result in:
Sashes that do not slide smoothly.
Holes in the frame which allow water to enter and cause damage and decay.
break down of the putty and allow water to penetrate, which could lead to decay of the frame and cill.
In the I920s and the I930s steel casement windows increased in popularity due to their durability slim and inexpensive and were in line with the trend for healthy living. However, research has shown that traditional softwood sash windows can be just as thermally efficient as double-glazed PVC-u windows and may be more appealing than the sleek lines of contemporary casement windows.
The window replacement industry has made a significant effort to persuade house owners that their old windows are old, dirty, and beyond repair. Many older timber windows can be fixed and used for many more years with minor repairs.
5. Maintenance
Traditional sash windows require regular maintenance and inspection. Failure to do this could 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 movement within the frame, causing the sash to not close correctly. The sash may also become stuck in its open position, allowing water and draughts into the building.
The damage to timber windows is often caused by moisture penetration. This can be prevented by thorough painting, periodic repairs, and removing the source of dampness. Wet rot is recognisable due to the wavy appearance of the paint that can be stripped to reveal soft, rotting wood. turning lock cambridge should be cut out and the affected area should be carefully scarfed or pieced in using replacements made of the same type of wood as the ones that remain. This method of repair increases the amount of fabric that is left and is one of the least invasive methods for treating timber-to-timber decay.
A wood condenser made of resin is a viable alternative to traditional staining or sanding. It is brushed onto the surface of the wood to protect it and stabilise it. It is particularly beneficial in the treatment of sash cords and pulleys which help prevent breakage.
It is crucial that any ironmongery from the past like sash stays and latches are kept and restored instead of replacing them. It is difficult to replace these items without compromising their original design. It is also recommended that modern fittings made of aluminium, such as sashlifts and chainstays, are avoided since they could cause corrosion and deterioration of timber frames and sashes.
