Maintaining Timber Windows

A well-maintained window repairs cambridge made of timber is an important element of the historic structure of a building. It illustrates in varying degrees the different materials and technologies, craftsmanship and architectural taste of the time period that it was built in.

Whenever possible repairs to existing windows are required, they should be done in situ. Repairing the worst areas of decay is possible by using specialized resin-based systems.

Durability

The windows made of wood in many historic buildings were made to last for a long time. They do require some maintenance to keep them looking great. The most frequent maintenance tasks include sash-cord upvc door repairs as well as tightening sash pulleys and painting. The demand for enhancing timber windows to improve efficiency and energy efficiency is also increasing. This may include replacing old glazing units, fixing the window rebates that are in place or installing new cills to improve air seal.

A key problem with traditional windows is the damage caused by the corrosion of the paintwork. This is particularly true when sash windows are involved as the gaps between the sashes can be quite large. In these instances, water can penetrate paint film and cause rotting of the wood or putty beneath. The rotting process can be made worse due to weather conditions that are poor. To prevent this from happening, windows should be painted regularly with an exterior wood paint.

The areas that are damaged should be repaired using resin-based products. This will ensure that the best possible amount of the original fabric is retained. It is also necessary to reduce the number of holes that are drilled into the frame to allow cable entry, as they could allow water in and cause decay.

The wall's structural movement can also lead to distortions in the frame as well as the sash. This can lead to sash no longer fitting correctly and jamming or sticking to the opening and broken glazing. This can be corrected often by fitting new frames for sash made of slow-grown deal (pine), or oak. The cill should be made from durable hardwood such as oak to prevent movement between the existing and new work.

To reduce the risk, there are now a number of companies who manufacture Boston pattern sash made of wood that will fit into the majority of existing openings. They are available in a variety of sizes and finishes to meet the needs of the modern homeowner. The new sash, combined with quadruple draft strips and a better thermal insulation, can significantly improve the efficiency of a home's energy use.

Aesthetics

Many old timber windows have a high aesthetic value as they often illustrate, in some way, the materials and technology and architectural style of the time from which they originate. They may also have a significant historic value in their own right. This is particularly true of early windows that were not glazed in timber-framed structures, where the majority were series of openings within frames of structural construction, which were divided horizontally by mullions and vertical wood or iron bars in order to protect against intruders.

Traditional timber window joinery is a beautiful aspect of a building, and is essential to maintain its appearance. When you spot any signs of decay caused by moisture penetration, it is important to stop it. This can be done by painting thoroughly, especially in areas where there has already been damage or degradation. It is best to choose paints that are intended to be used in a set (primer undercoat and finish) and to follow the manufacturer’s recommendations for preparation and number coats at each stage.

Wet rot is a typical issue in old timber windows. The best method to stop it from growing is to eliminate any damaged or rotten sections immediately to prevent the spread of the fungus responsible for it. The replacement of wood that is rotting should be done with care and using slow grown deal (pine) and, whenever possible it is the same species as that which is being removed in order to prevent differential movement between the new section and the existing timbers.

In the late medieval and 17th century periods glass became cheaper and more plentiful so that glazed openings in timber-framed buildings gradually became sophisticated, with tracery made of wood, moulded mullions and deep protruding cills. The double glazing seal repairs was increasingly laid within rebated frames and then pinned with 'glazing sprigs' rather than being inserted into lead cames. This method of glazing is not only less prone to leaking but it can allow for much wider clearer, more transparent sheets of glass to be used in the windows than would otherwise be possible without the need for leaded lights.

Energy efficiency

Traditional timber windows have a good energy performance due to their thickness and multi-layer construction. They also pay attentive attention to detail. They also have large glass areas and projecting cills that reduce air infiltration. The windows can be modified to improve their energy efficiency by draught-proofing and secondary glazing. However it is crucial to keep in mind that these measures must be considered in terms of the overall quality and appearance of the window maintenance in its original form.

Therefore, keeping existing historic windows that require repair rather than replacing them is sensible, particularly when their thermal enhancements can be achieved economically through simple repairs and upgrades. The windows that are historic have a lot of historical significance, since they reflect a variety of technical development and changes to architectural style. The pressures to replace these windows are usually based on the assumption that the old windows will need replacement in the near future, however the majority of them are capable of serving for 150, 200 or even 250 years if properly maintained.

It is essential to realize that decay issues with traditional timber windows are avoidable with quick and thorough repairs. Additionally it is vital to identify damp penetration problems and to remedy them quickly to prevent serious damage. Paint deterioration that occurs early is a concern because it allows moisture to get into the wood, which can cause wet rot. The damage is usually not evident until the paintwork is wavy or cracked however, it can cause serious structural damage and can lead to further decay.

A good paint will block moisture penetration. To prevent mould and condensation, it is important to keep the paintwork as clean as you can. Modern synthetic paints pose a problem since they are usually water-resistant and may cause mildew growth in the window frame.

The majority of older windows were manufactured from timber containing an extensive proportion of sapwood. These timbers deteriorate quickly if exposed to rain, but they can be protected with a thorough preservation process prior to use. It is crucial to select the right kind of wood for the site and climate, as these variables can affect the durability of the joinery. Local window manufacturers provide a wide range of sash made from timber that can be adapted to fit historical openings. They can be made according to the standard Boston pattern dimensions or to custom sizes that fit with the historic architecture.

Maintenance

The life of timber windows can be extended significantly through regular inspections as well as a careful redecoration and prompt Upvc Door Repair Cost. The main cause of decay is the infiltration of moisture through deteriorated paint and putty. This can be avoided by using a good wood preservative and painting the wood thoroughly.

It is crucial that repairs to old sash or casement windows are done correctly and done without causing any disturbance. Many traditional timber window and door repair near me designs are repairable without removing the frame, and this method should be used whenever it is feasible. Remove loose or peeling paint and lightly sand the area to improve the 'key" of the surface. This will allow the new coating to stick better. Be careful to avoid stripping old paint layers which might have historical significance and if they are present it is recommended that a study of the paint be conducted.

If a piece of wood has rotted the best option is to take it off and replace it with timber inserts shaped to match the existing profiles. The timber that is inserted should be treated with wood preservative, and the joint between masonry sub-cills and timber cill should be sealed.

It can be tempting to replace traditional windows with PVC U, particularly if the installer offers an 'all-in-one' installation which includes removal and replacement within a single day. It is important that the installers of replacement windows have a deep understanding of the history and construction of traditional timber frames. This will enable them to make the right suggestions for energy efficiency improvements and other technological improvements that don't alter the appearance of a historic building. The windows that are replaced should be registered under a Competent Persons Scheme like as FENSA. This will ensure that the replacements are deemed as a suitable option under Building Regulations. It is quite possible for a skilled and experienced carpenter to install PVC-U windows that are sympathetic to the the building originally. This is especially relevant when windows are situated within listed buildings or conservation areas.
