How to Restore Timber Sash Windows in cambridge windows

Many homes in Cambridge have sash windows that are traditional and 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 wood to expand.

Box sash windows were traditionally operated by chains or cotton cords as well as lead weights. Modern sash window springs are hidden to avoid this issue.

1. Aesthetics

Timber sash windows, in contrast to PVC-u windows which are manufactured in imperial sizes, which are modular, can be reconstructed to original dimensions. This allows the restoration to meet the current energy standards while complying with conservation area regulations. It also provides an option that is superior to the upvc windows cambridge options.

Sliding frames for windows made of sash were originally only used for large buildings or public buildings. However, this changed when production became cheaper and artisans could produce larger frames with larger glass. At the close of the 18th century, sash windows had become the most popular wooden design in British homes. Since they were easy to open, sash windows let light into rooms without the need for curtains.

The early windows were made of plain glass, but in the 17th century the sash windows began 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 a common feature in many historic homes.

In the 19th century, it became possible to make large, sturdy glasses that didn't need supporting bars. This allowed the frame size to be enlarged further, which allowed for a wider view from 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 at the beginning of the I930s. The double-hung sliding sash was another important improvement that was made at the end of the I920s and at the beginning of the I930s.

Oak was used in older examples and more prestigious buildings. A split bead divides the two sashes, and it is essential that it is maintained to prevent rattles and draughts. It is also important that sash pulleys and idler wheels are kept in good working order as they assist in operating the window doctor.

2. Energy efficiency

Sash windows replaced hinged cases as clearer and larger sheets were made available. They were coated with plate glass that was placed within timber frames with rebates and then pinned with glazing sprigs, with putty on both sides to create a watertight seal. This type of glazing gradually replaced the use of leaded lights.

Sashes were introduced, which led to a greater demand for ironmongery. The most common fittings included brass pulleys (and later cast-iron) weights, sash stoppers shutter hinges and handles, and various fasteners used to secure the sashes. They were often decorated with designs, inscriptions, and patterns engraved to identify the maker.

With regular maintenance, sash windows can be very energy efficient. But, if you don't maintain them, they can become drafty and let in cold air. Draughts can also result from the degeneration of paint and putty. This can be corrected using wood-to-timber repair products that are specifically designed for this purpose.

The industry of replacement windows is based on the belief that traditional windows are rotten and beyond economical repair, but they can be easily maintained with just a little care. Repairs To Upvc Doors can be expensive and cause a lot of disruption in 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 home within a single day, eliminating the need to co-ordinate different tradesmen, making the whole process much more efficient. They can also be supplied with energy-saving double-glazing to get higher energy efficiency ratings than those offered by traditional sash windows. These double-glazed windows aren't capable of resembling the proportions and sections of sashes from old timber.

3. Security

Traditional windows can be secured without compromising their appearance. A variety of ironmongery types can be installed, including sash chains, mortice bolts and sash locks. These can be installed in a manner that the window can 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 alongside traditional sash window catches and must be replaced by more robust versions (such ones with double screws) or sprung levers to reduce the possibility of them being opened by hammering.

Sash-window frames were traditionally made from slow-growing deal or, in the more prestigious houses they were made from oak. Where glazing bars have survived they should be kept, and, if it is possible, the timber of the cill should be replaced by identical wood. PVC-u companies often offer a one stop shop installation service, which includes removing and replacing windows across a home in a single day without the need to involve other tradespeople, or coordinate visits from a number of different suppliers.

4. Ventilation

Sash windows were introduced in the 17th Century and allowed for a significant amount of light into buildings. In the 18th century, they were modified so that more light could be let into rooms. Larger glass panes were also produced. The result was a much lighter appearance and windows with a higher level of elegance than they had before.

The introduction of sash windows also necessitated the creation of a new line of ironmongery. Early pulleys were made from wood, while later Victorian ones could be made from brass or a mixture of lead and wood and there were many kinds of shutter hinges and knobs. Ironmongery elements must be maintained and cleaned so that the fine quality of their design can be appreciated.

To keep them in good condition, timber windows must be maintained. Inattention to maintenance could lead to:

Sashes that do not slide smoothly.

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

Water can get into the putty and cause decay to the frame or cause cill.

Steel casement windows gained popularity in the I920s and I930s due to their strength and slim, cost-effective and matched the trend of healthy living. However, research has proven that traditional softwood sash windows are just as efficient thermally as double-glazed windows made of PVC-u, 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 old windows are dirty, noisy and beyond repair. However, many old timber windows are in good condition and with minor repairs could easily be maintained for years to come.

5. Maintenance

A traditional sash window requires regular maintenance and inspection. If you don't maintain your sash window, it can cause the sash cords breaking and the glazing bars deteriorating excessively. It can also cause paint and putty to degrade. The removal of sashes may also cause structural movement in the frame, which can cause the sash to not close properly. The sash may also become stuck in the open position, which allows the water and drafts to enter the building.

Damage to windows made of timber is often caused by water infiltration. This can be avoided by regular upvc doors repairs as well as thorough painting, and then removing the cause of dampness. The paint can be removed to expose the soft, rotting wood. Any rotten timber sections must be removed and the affected area carefully cut or pieced with replacements made from the same type of timber as those remaining. This method of repair maximizes the amount of original fabric that is left and is one of the least invasive methods of treating decay caused by timber.

The use of a resin-based wood consolidant is a different option to traditional staining and sanding. The product is brushed on to the surface of the wood to stabilize it and protect it from further damage. It is especially beneficial to treat pulley cords and sash where it can prevent breakage.

It is crucial that any historic ironmongery like sash stays and latches are retained and restored rather than replaced. These items can be very difficult to replace without damaging the the 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.
