How to Restore Timber Sash Windows in cambridge windows and doors

Many homes in Cambridge have traditional sash windows and homeowners are proud of the way they appear. However, sash windows can get stuck and be difficult to open or close. This is usually due to moisture that can cause the wood to swell.

Traditionally, window boxes utilized chains, cotton cords or weights made of lead to operate. Modern sash windows have hidden springs to overcome this issue.

1. Aesthetics

Timber sash windows, in contrast to PVC-u windows that are made in imperial sizes, which are modular, can be reconstructed to their original dimensions. This allows the restoration of timber sash windows to meet the current energy requirements and conform to conservation regulations for areas. It also provides windows that have a superior appearance than the upvc locksmith cambridge doors repairs (Get Source) alternatives.

Sliding frames for windows made of sash were originally intended for large structures or public buildings. However, this changed when production became less expensive and craftsmen could make larger frames using larger glass. By the late 18th century sash windows were the dominant wooden design in most British homes. As they were easy to open, sash windows let light into rooms without the need for curtains.

The first windows were made of clear glass however, in the 17th century, sash windows began to be more decorative. They began with colored glazing bars, also known as mullions. These windows were quite expensive at the time but as glass production became more efficient and less expensive, they became a feature of many period houses.

In the 19th century, it was possible to make large, strong glasses that didn't require support bars. This allowed for the frame to be made bigger which, in turn, provided the viewer a better view. This was a significant advancement.

The introduction of the double-hung sliding sash is another important improvement that was made towards the end of the I920s and the beginning of the 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.

The most popular type of sash is constructed from slow-growing deal (pine) but oak was also used in more prestigious buildings and in some earlier examples. A parting bead is used to separate the two sashes. It is essential that it is well maintained to prevent rattles and drafts. It is also important that the idler and sash pulley wheels are in good condition as these help to operate the window.

2. Energy efficiency

Sash windows replaced hinged casements as clearer and larger sheets became available. They were coated with plate glass that was set in timber frames with rebates and secured with glazing sprigs, with putty on both sides to make them watertight. This type of glazing gradually replaced leaded lights.

The introduction of sashes led to an need for a larger variety of ironmongery with the most basic fittings being brass pulleys, lead (and later cast iron) weights, sash stoppers shutter hinges and knobs and a variety of fasteners to hold the sashes into place. These were often decorated with motifs, inscriptions, and engraved patterns that identified the maker.

Sash windows are energy efficient when they are maintained regularly. However, without this maintenance they can become drafty and let in cold air. Draughts can also be caused by the deterioration of putty and paint. This can be fixed by making use of wood-to-timber repair tools that are proprietary.

The industry of replacement windows cambridge windows is based on the perception that older windows are old and beyond economical repair, while they can be easily maintained with just a little care. However, repairs to these windows can be costly and cause considerable disruption to the home. Many homeowners opt to replace their windows with PVC-u from a "one-stop shop" company for installation. They can replace all windows in a house in one day, saving time and avoiding the need for various 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 historic timber sashes.

3. Security

Traditional windows can be secured without compromising their appearance. There are many types of ironmongery that can be fitted, including sash chains, mortice bolts and sash locks. They can be positioned in a way so that the window can still be opened for ventilation and cleaning. These are typically unobtrusive, as they are designed to fit the sash window. They can be used alongside traditional sash-window catches that should be replaced with more robust versions (such ones with double screws) or spring-loaded levers to minimize the chance of them being opened by hammering.

Sash-window frames were traditionally constructed from slow-growing deal or, in more elegant homes, from oak. Where glazing bars have survived they should be kept, and if it is it is possible, the timber of the cill should be replaced with the same wood. Many PVC-U firms provide a one-stop shop installation service. They can take out and replace windows on a complete home in a single day, without involving any other tradespeople.

4. Ventilation

When sash windows were first introduced in the 17th century, they allowed a substantial amount of light into structures. At the end of the 18th century, they had been modified so that more light could be let into the rooms. Larger glazing panes were also produced. The result was a more light appearance and windows that were more elegant.

The introduction of sash windows also demanded a new range of ironmongery. Early pulleys were made from wood, whereas later Victorian ones could be made of brass or a mixture of wood and lead, and there were various types of shutter hinges and knobs. The ironmongery pieces need to be cleaned and preserved to appreciate their beautiful design.

Timber windows require regular maintenance to keep them in good condition. Inattention to maintenance could lead to:

Sashes that do not move smoothly.

holes in the frame that allow water, which can cause damage and decay.

The putty can be soaked by water and cause decay to the frame or cause cill.

In the I920s and I930s steel casement windows gained popularity due to their strength slim and affordable and also matched the fashion for healthy living. Research has shown that softwood sash windows are as efficient as PVC-u windows and can even be more attractive.

The industry of replacement windows cambridge windows has done a lot to persuade house owners that their traditional windows are rotten, draughty and beyond economic repair. Many older timber windows can be fixed and used for many more years with minor repairs.

5. Maintenance

The traditional sash windows need regular maintenance and inspection. If you do not maintain your sash window, it could cause the sash cords breaking and the glazing bars deteriorating excessively. It could also cause paint and putty to become damaged. The removal of sashes could also result in structural movement within the frame which causes the sash to be misaligned and unable to close correctly. The sash may also become stuck in an open position, allowing the water and drafts to enter the property.

Moisture penetration is a frequent cause of damage to windows made of timber. This can be avoided with regular repairs as well as thorough painting, and then removing the source of dampness. The paint can be removed to reveal the soft, decaying wood. Any rotten sections of timber should be cut off and the affected area should be carefully scarfed or pieced in using replacements made from the same kind of timber as those remaining. This repair method increases the amount original fabric and is among the most minimally invasive methods of treating the rot that occurs between timber and timber.

A wood condenser that is based on resin is an alternative to the traditional process of sanding or staining. The product is brushed on the surface of the wood to protect it and stabilise it. It is particularly useful for the treatment of sash cords and pulleys which can help stop breakage.

It is crucial to restore and not replace any old ironmongery such as sash latches and stays. They can be extremely difficult to replace without compromising the quality of the original design. It is recommended that the use of modern aluminum fittings such as chain stays and sash lifts is avoided if at all possible since they can cause corrosion and deterioration of timber frames and sashes.
