Is Tech Making Sash Windows Cambridge Better Or Worse?
How to Restore Timber Sash Windows in Cambridge
Many homes in Cambridge have traditional sash windows and homeowners are proud of how they appear. Sash windows can become stuck and become difficult to open or close. This is usually due moisture that can cause the wood to swell.
Box sash windows were historically operated by chains or cotton cords as well as weights made of lead. Modern sash window springs are hidden to eliminate this issue.
1. Aesthetics
Timber sash windows, in contrast to PVC-u windows, which are made in imperial sizes, which are modular, Windows Cambridge can be reconstructed to original dimensions. This allows the restoration of timber sash windows in order to comply with current energy standards and to comply with conservation area regulations. It also offers windows with a more attractive appearance than upvc door repairs cambridge alternatives.
Sliding sash windows were initially only used in large buildings or public buildings, however this changed when production was less expensive and craftsmen were able to produce larger frames with more 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 allowed light to enter rooms without the need for curtains.
The early windows were made of plain glass however, by the 17th Century the sash windows cambridge [mouse click the following article] began to become more attractive. They were initially made of colored glazing bars, also known as mullions. These windows were quite expensive at the time, but as glass production improved and cost-effective, they became a feature of many of the period homes.
In the 19th century, it became possible to create large, sturdy glasses that didn’t require supporting bars. This allowed the frame size to be enlarged more, which in turn allowed for a wider view from the window. This was a significant improvement.
Another significant improvement was the introduction of the double-hung sliding window at the end of I920s and at the beginning of the I930s. The double-hung sliding sash was another significant improvement that came about at the end of the I920s, and at the beginning of the I930s.
Oak was used in older examples and more prestigious buildings. A parting bead separates the two sashes and it is essential that it is maintained in order to avoid rattles and drafts. The idler wheels, sash pulleys and sash rollers also are essential for the proper operation of the window.
2. Energy efficiency
Sash windows replaced hinged casements as clearer and larger sheets were made available. Glass plates were set in frames made of timber, which were secured with glazing sprigs and putty was then sprayed onto the frame’s two sides for watertightness. This kind of glazing gradually replaced the use of leaded lights.
The introduction of sashes resulted in a need for a much greater variety of ironmongery, including the most basic fittings, brass pulleys as well as lead (and later cast iron) weights, sash stoppers shutter hinges, knobs and shutters and a variety of fasteners used to keep the sashes in the right place. They were often decorated with motifs, inscriptions and engravings that identified the maker.
Sash windows can be very energy efficient when they are maintained regularly. Without this maintenance they can get draughty. Paint and putty may cause draughts. This can be remedied by using wood-to-timber repair products that are specifically designed for this purpose.
The replacement window industry relies heavily on the notion that old windows are beyond repair and are not able to be maintained economically. However, they can easily be maintained with a little attention. However, these repairs can be expensive and involve considerable disruption to the home. Many homeowners choose 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, thereby saving time and avoiding the need for different tradesmen to coordinate. They can also be fitted with energy-saving double-glazing to achieve more energy efficient ratings than are possible with traditional windows with sash. These double glazing in cambridge-glazed units are not capable of resembling the proportions and sections of the sashes made of timber from the past.
3. Security
Traditional windows can be secured without compromising their aesthetics. There are many types of ironmongery that can be installed with sash chains, mortice bolts and sash locks. These can be installed in a way so that the window can still be open for ventilation and cleaning. These products are often discrete since they are made to complement sash windows. They can be used in conjunction with traditional sash-window catches that must be replaced by more robust models (such ones with double screws) or sprung levers to reduce the chance of them being opened by hammering.
Sash-window frames were typically constructed from slow grown deal or, in more prestigious houses, from oak. When glazing bars have survived they should be kept and if it is feasible, the wood of the cill should be replaced by matching wood. PVC-U companies usually provide a one-stop shop installation service, removing and replacing windows across a house in a day without the need to involve 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 significant amount of light to be absorbed into buildings. By the end of the 18th century, they were adapted to allow even more light into rooms, and larger glass panes began to be made. The result was a lighter look and windows with more elegance.
The introduction of sash windows also demanded an entirely new range of ironmongery. Early pulleys were made from wood, later Victorian ones were made from brass or a combination of lead and wood, and there were a variety of shutter hinges and knobs. The ironmongery pieces need to be cleaned and preserved to appreciate their beautiful design.
Timber windows require careful maintenance to keep them in good shape. Lack of regular attention may result in:
Sashes that don’t slide effortlessly.
holes in the frame that allow water that can cause decay and damage.
break down of putty, allowing water penetration that can lead to decay in the frame and cill.
In the I920s and the I930s steel casement windows grew in popularity due to their durability, slim and cheap and also matched the fashion for healthy living. However, research has proven that traditional softwood sash windows are as thermally efficient as PVC-u double-glazed windows, and can be more attractive than the modern sleek design of casement windows.
The window replacement industry has done a lot to persuade house owners that their windows are dirty, noisy and beyond repair. Many old windows made of timber can be repaired and used for a long time with minor repairs.
5. Maintenance
Traditional sash windows require regular maintenance and inspection. If you do not maintain your window’s sash, it could cause the sash cords breaking, and the glazing bars deteriorating 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 move out of alignment and unable to close correctly. The sash can also be stuck in an open position, which allows water and draughts to enter the building.
Damage to windows made of timber is usually caused by moisture entry. This can be prevented by thorough painting, periodic repairs and the elimination of the cause of dampness. Wet rot can be identified due to the wavy appearance of the existing paint which can be stripped to reveal soft, rotting timber. Any rotten timber sections must be removed and the affected area carefully scarfed or pieced in using replacements made from the same type of timber as the ones that remain. This method of repair increases the amount original fabric and is one of least invasive ways to treat the rot that occurs between timber and timber.
The use of a resin-based wood consolidant is another alternative to traditional sanding and staining. It is brushed onto the surface of the wood to protect it and strengthen it. It is particularly useful in the treatment of pulleys and sash cords which help prevent the breakage.
It is essential that any old ironmongery like sash stays and latches are retained and rehabilitated instead of being replacing them. It is difficult to replace these items without compromising their original design. It is also advised that modern aluminium fittings like sashlifts, as well as chainstays, should be avoided since they could cause corrosion and deterioration of timber frames and sashes.
