11 Ways To Fully Redesign Your Sash Windows Cambridge

How to Restore Timber Sash Windows in Cambridge

Many homes in Cambridge feature traditional sash window and homeowners are proud of their appearance. Sash windows can become stuck and be difficult to open or close. This is typically due to moisture which can cause the wood to swell.

Traditionally, box sash windows used chains or cotton cords and weights made of lead to operate. Modern sash windows come with hidden springs to address this issue.

1. Aesthetics

In contrast to PVC-u windows, which are made to modular imperial sizes the timber sash windows are able to be restored to their original sizes. This allows for the restoration of timber sash windows in order to comply with current energy standards and comply with conservation area regulations. It also offers an option that is superior to the uPVC alternatives.

Sliding sash windows were initially only used in large structures or public buildings, but the production process was less expensive and craftsmen were able to produce 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. Because they were simple to open sash windows allowed light into rooms without the need for curtains.

The early windows were made of glass that was plain, but in the 17th century sash windows started to become more ornamental. They were initially made of colored glazing bars, also known as mullions. They were expensive initially, but when glass production became less expensive and more efficient, they were commonplace in many historic homes.

In the 19th century, it was possible to create large, sturdy glass that didn't require support bars. This allowed the frame's size to be increased even more, which in turn allowed for a wider view out of the window. This was a significant advancement.

The introduction of the double-hung sliding sash is another important improvement that occurred towards the end of the I920s and the beginning of the 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. A parting bead separates the two sashes. It is vital that it is well maintained to prevent rattles and drafts. It is also important that sash pulleys and idler wheels are in good working order as they aid in operating the window.

2. Energy efficiency

As larger and clearer sheets of glass became available, sash window began to replace hinged casements. Plate glass was placed in frames made of timber, which were which were pinned with glazing sprigs, and putty was sprayed on the frame's sides for watertightness. This form of glass gradually replaced the leaded light bulbs.

Sashes were introduced, which led to increased demand for ironmongery.  RepairMyWindowsAndDoors  included brass pulleys (and later cast-iron) weights, sash stoppers shutter hinges, handles and shutter hinges, and a variety of fasteners to fix the sashes. They were often decorated with motifs, inscriptions, and engravings that identified the maker.

Sash windows can be very energy-efficient with regular maintenance. Without this maintenance, they can become drafty. Draughts can also be caused by the deterioration of paint and putty. This can be remedied by using wood-to-timber repair products that are specifically designed for this purpose.

The industry of replacement windows relies heavily on the belief that old windows are damaged beyond repair and are not able to be maintained economically. However they can be maintained with a bit of attention. However, these repairs can be costly and cause significant disruption to your home. To prevent this homeowners often prefer to replace their windows with PVC-u windows from one of the largest "one-stop shop" installation companies. These can remove and replace all windows in an entire house within a single day, avoiding the need to coordinate different tradesmen, making the whole process much quicker. They are also available with 'energy saving' double-glazing to get higher energy efficiency ratings than traditional windows made of sash. Double-glazed windows aren't capable of resembling the proportions and section of historic timber sashes.

3. Security

Traditional windows can be secured without compromising their style. Ironmongery, such as mortice bolts, sash chain and sash lock could be put in place. They can be fitted so that the window is open to allow ventilation or cleaning. These products are usually minimal in appearance, as they are designed to match the sash window. They can be used with traditional sash window catch. These should be replaced by more robust models, such as those with double screws, or sprung levers to decrease the risk of being struck by hammers.

Sash-window frames were made from slow-growing deal or, in more prestigious houses they were made from oak. If the glazing bars remain intact, they should be retained. If it is possible, the timber cills should be replaced with wood that is in line with. PVC-U companies usually offer a one stop shop installation service that can remove and replacing windows on an entire home in one day, without the need to engage other tradespeople, or coordinate visits from different suppliers.

4. Ventilation

Sash windows were introduced in the 17th Century and allowed for a huge amount of light to enter buildings. By the end 18th century, they had been adapted so that even more light could be let into rooms. Larger glazing panes were also made. The result was a lighter look and windows with more elegance.

Sash windows were introduced and required a new type of ironmongery. Early pulleys were made out of wood. Later Victorian ones were made of brass or a mixture of wood and leaded. There were also different kinds of knobs and shutter hinges. These ironmongery pieces must be maintained and cleaned to appreciate their exquisite design.

To ensure they remain in good condition, wooden windows require regular maintenance. Inattention to maintenance can lead to:

Sashes that do not slide smoothly.

Holes in the frame that allow water to get in and cause damage and decay.

break down of the putty and allow water penetration, which could cause decay in the frame and cill.

In the I920s and I930s, steel casement windows gained popularity due to their strength, slim and cheap and were in line with the trend for healthy living. However, research has shown that traditional softwood sash windows can be just as efficient in thermal efficiency as PVC-u double-glazed windows, and are more attractive than the modern sleek design of casement windows.

The replacement window industry has made a significant effort to persuade house owners that their windows are old, dirty, and beyond economic repair. However, many old timber windows are in good shape and with minor repairs could easily be repaired for many years to be.

5. Maintenance

A traditional sash window needs regular maintenance and inspection. Inability to keep up with this can lead to broken sash cords, excessive wear on the glazing bars and degradation of the paint and putty. The removal of sashes can also result in structural movement within the frame, causing the sash to not close properly. It is also possible for the sash to be snagged or slammed into an open position, which can let water and draughts enter the structure.

Moisture penetration is a frequent cause of damage to timber windows. This can be prevented by regular repairs by thorough painting and eliminating the source of dampness. Wet rot is recognisable due to the wavy appearance of the paint, which can be removed to reveal soft, rotting wood. Any rotten sections of timber must be removed and the affected area carefully cut or pieced with replacements made from the same type of timber as the ones that remain. This method of repair maximises the amount of fabric retained and is one of the least invasive ways of treating decay of timber to timber.

The use of a wood consolidant made from resin is another alternative to traditional sanding and staining. This is brushed onto the surface of the timber to help stabilize it and shield it from further damage. It is particularly useful for the treatment of pulleys and sash cords where it can help to prevent breakage.

It is essential to preserve and not replace any historical ironmongery, such as sash latches and stays. It is difficult to replace these items without altering their original design. It is also recommended that fittings made of aluminum like sashlifts, as well as chainstays, are avoided since they can cause corrosion and deterioration of timber frames and sashes.
