Maintaining Timber Windows

A well-maintained wooden window is an essential component of a historical building. It reflects in different degree the materials and techniques of the time in which it was constructed, the design and craftsmanship.

Whenever possible repairs to windows that are already in use should be done in-situ. The repair system that is based on resin can be used to fix the most deteriorated areas without having to remove the entire window.

Durability

The timber windows in many old buildings were built to last for a long time. But, they have to be maintained to ensure they look good and functioning correctly. Maintenance tasks include repairs to sash cords, retightening of pulleys for sash and painting. The demand for upgrading timber windows to improve efficiency and energy efficiency is also increasing. This may mean replacing old glass units, fixing the window rebates that are in place, or installing new cills to allow for better air sealing.

The deterioration of paintwork is a major issue with traditional windows. This is particularly important when sash windows are involved as the gaps between sashes can be quite wide. In these instances, water can penetrate paint film and cause rotting to the wood or putty underneath. The rotting may be further aggravated by weather conditions that are not ideal. To avoid this windows, they should be painted regularly using an exterior wood paint that is suitable.

In addition to repainting, areas that have corroded need to be repaired with the help of a resin-based repair solution. This will ensure the maximum amount of the original fabric is preserved. It is crucial to reduce the number of holes drilled in the frame to allow cable access, because they could let in moisture and cause decay.

Another issue with older windows is structural movement in the wall which can lead to deformation of the frame and sash. This could result in sash no longer fitting correctly or sticking or jamming into the opening and cracked glazing. Often this can be corrected by the fitting of new sash boxes constructed from slow-growing deal (pine) or oak. The cill needs to be constructed of a durable hardwood, such as oak, to avoid differential movement between new and older work.

There are several companies that produce Boston pattern wooden sash to fit into the majority of existing openings. The sash is available in a variety of sizes and finishes that will suit the needs of modern homeowners. Together with quadruple draught strips and a better thermal insulation, these sashes can make a a substantial difference to the energy efficiency of a house.

Aesthetics

Many old timber windows have a great aesthetic value as they often illustrate, in some way, the materials and technology and architectural style of the time in which they originate. They could also have a significant historical significance in their own right. This is especially true for early windows that were not glazed in timber-framed structures, which were simply a series of openings within the frame that were subdivided horizontally into mullions and vertical wood or iron bars to keep out intruders.

Traditional window joinery made from timber is a beautiful aspect of a building, and it is important to keep its appearance. When you spot any signs of decay due to moisture penetration it is crucial to stop it. It is best to do this by thorough painting, particularly if there has been damage or degradation. It is advisable to use paints specifically designed to be used as part of a system (primer undercoat, finish) and follow the manufacturer's instructions in terms of preparation and the amount of coats needed at each stage.

The fungus that causes wet rot can quickly spread in old windows made of wood. To prevent this from happening, remove any damaged or rotten components as soon as you can. The replacement of wood that is rotting should be done with care and using slow grown deal (pine) and, whenever possible using the same species as that which is being removed in order to prevent any movement differences between the new and old timbers.

Glass became less expensive and more abundant during the late medieval period and into the 17th century. In the process, the glazed openings in timber-framed homes became more complicated with moulded mullions, tracery made of wood and deep projecting cills. In recent years, glazing was pinned into frames that were rebated using glazing sprigs rather than lead cames. This method of glazing not only makes windows less likely to leak and also allows wider sheets of clearer glass to be used than would have been feasible without the use of led lights.

Energy efficiency

Traditional timber windows offer excellent energy efficiency due to their thickness and multi-layer construction. They also pay careful attention to detailing. The large glass areas, the deep projection cills and wide double glazing repairs near me areas reduce air infiltration. Windows can be designed to increase their energy efficiency by draught-proofing and secondary glazing. It is important to keep in mind that these measures must be considered in relation to the overall integrity and look of the original windows.

It is sensible to repair or upgrade existing historic windows rather than replace them, especially when the improvement in thermal efficiency can be achieved through simple repairs. Historic windows are often of historical value, as they demonstrate a variety in technological advancements and changes to architectural taste. The pressures to replace these windows are generally based on the assumption that windows of the past will require replacement in the near future, but most are still in a position to last for 150, 200 or even 250 years if properly maintained.

It is crucial to understand that decay problems with traditional timber windows can be preventable by prompt and thorough repairs. It is also important to spot damp issues and fix them quickly so that you can avoid serious damage. Early deterioration of paint is a major problem as it allows moisture to penetrate the wood and cause wet rot. The damage is usually not evident until the paintwork becomes cracking or wavy, but can cause significant structural damage and can lead to further decay.

A good paint will block moisture penetration. To prevent condensation and mould, it is important to keep the paintwork as clean as you can. Modern synthetic paints are problematic since they are usually water-resistant and can cause mildew to develop within the window mechnism repair; just click the following article, frame.

The majority of older windows were constructed of sapwood-rich timber. These timbers can deteriorate very rapidly if exposed to wet weather conditions, but they can be preserved with an extensive preservative treatment prior to when they are put to use. It is also important to ensure that the kind of wood used is suited to the climate and site conditions, as these factors can affect the longevity of the joinery. Local window manufacturers make various types of timber sash that can be adapted to fit specific openings in historic buildings. They can be made 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 by regular inspection as well as a careful redecoration and prompt repair. The major cause of decay is moisture leaking through deteriorated paint and putty. This can be prevented by using a quality wood preservative and painting the wood thoroughly.

Repairs to old sash windows as well as window frames made of casement must be done with care and minimal disruption. Many traditional timber window designs can be repaired without dismantling the frame, and this method should be taken whenever possible. Peeling or loose paint must be removed with care and sanded lightly to increase the "key" of the surface and facilitate an improved adhesion of the new coating. Be careful to avoid stripping paint layers that might have historical significance and if they are present it is recommended that a study of the paint be conducted.

When a section of wood is decayed the best way to deal with it is to take it off and replace it with timber inserts shaped to match the existing profiles. The timber inserts should be treated using wood preservative, and the joint between masonry sub-cill and timber cill should be sealed.

It can be tempting to replace traditional windows with PVC u, particularly when the installer provides an installation that includes both 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 technical improvements that do not alter the historic character of a building. The windows that are replaced must be registered under a Competent Persons Scheme such as FENSA. This will ensure that the replacements are deemed as a suitable solution in accordance with Building Regulations. It is quite possible for an experienced and skilled carpenter to install PVC-U windows that are sympathetic to the style of the original building. This is particularly true when the windows are situated within listed buildings or conservation areas.
