Maintaining Timber Windows

A well-maintained window made of timber is an important element of the historical fabric of a building. It illustrates in varying degrees the different materials and technologies as well as the craftsmanship and architectural style of the period from which it dates.

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

Durability

The windows made of timber in many old structures were designed to last for a long time. But, they have to be maintained to ensure they look good and operating correctly. The most common maintenance tasks include repairs to sash cords, re-tightening sash pulleys, and painting. There is also a rising demand for upgrading timber windows to increase the efficiency of energy. This may mean replacing old glazing units, repairing existing window rebates, or installing new cills for improved air sealing.

The deterioration of paintwork is a major problem with traditional windows. This is especially important where windows made of sash are involved because the gaps between the sashes can be very wide. In these situations, water can penetrate the paint film and cause rotting of the putty and the wood beneath. The rotting may be further aggravated due to weather conditions that are poor. To avoid this windows from becoming rotten, they must be painted regularly with a suitable exterior wood paint.

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

The structural movement of the wall could also cause distortions in the frame and the sash. This can result in the sash not fitting properly and jamming or sticking into the opening, and even broken glass. This is often corrected by putting in new sash frames made of slow-grown deal (pine), or oak. The cill should be made from a sturdy hardwood such as oak to avoid differential movement between the existing and new work.

There are several companies that make Boston pattern wooden sash that fit most existing openings. The sash is available in various sizes and finishes that will suit the needs of modern homeowners. In conjunction with quadruple draught strip and a better thermal insulation, these new sash options can make a substantial difference to the energy efficiency of a home.

Aesthetics

Many old timber frames have a great aesthetic appeal, since they reflect, in some form, the materials, technology, and architectural aesthetics of the time they were built. They also may have a significant historic value in their individual cases. This is especially true of early unglazed window openings in timber-framed structures, where the great majority were merely a series of openings within the frame, which were divided horizontally into mullions and wood or iron bars to deter intrusions.

It is crucial to maintain the appearance of traditional wooden window joinery. It is vital that any decay resulting from moisture penetration should be immediately stopped once it is identified. It is recommended to do this by thorough painting, especially if there is damage or degradation. It is recommended to use paints that are specifically designed to be used part of a system (primer as well as undercoat, finish and primer) and follow the manufacturer's instructions regarding preparation and the number of coats required at each stage.

Wet rot is a frequent problem for old timber windows and the best way to stop it becoming a problem is to take out sections that are damaged or rotten as soon as possible to stop the spread of the fungus that causes it. Replace rotting wood with slow-growing deal (pine) and, when possible, the exact type of wood that is being removed, to avoid the possibility of differential movement.

Glass became more affordable and abundant in the late medieval era and into the 17th century. This led to glazed openings on timber-framed houses became more complex with moulded mullions and traceries, made of wood and deep cills projecting into the air. In recent years, glazing was fixed to rebated frames with glazing sprigs, not lead cames. This method of glazing is not only less susceptible to leaks, but it also allows larger clearer, upvc Repairs more transparent sheets of glass to be used in the windows than would have been possible without the need for lead lights.

Energy efficiency

Traditional timber windows provide an excellent energy performance due to their thickness and multi-layer construction. They also pay attentive attention to detail. They also feature large glass areas as well as deep projecting cills that reduce air infiltration. With secondary glazing and draughtproofing, windows can be made more efficient to increase their energy efficiency. It is essential to keep in mind that these measures must be considered in relation to the overall integrity and look of the original windows.

As a result, retaining old windows that are in need of repair instead of replacing them is logical, particularly when their thermal enhancements can be made cost-effectively through simple upvc door handle repairs near me and upgrades. Older windows typically have a historical value that demonstrates a range of technological advances and changes in architectural style. Most people think that the windows will need to be replaced in the near future. However, most can still provide service for 150,200, and even 250 years if you take care of maintenance.

It is important to recognize that decay issues associated with traditional timber windows are easily prevented with prompt and thorough repairs. In addition, it is essential to spot damp penetration issues and address them swiftly to avoid major damage. Early deterioration of paint is a particular problem, as it allows moisture to penetrate the wood and cause wet rot. It is not uncommon for this issue to go undetected until the paintwork begins to crack or become wavier. However, it could cause structural damage and then further decay.

A good quality paint will stop this moisture from entering. It is also necessary to keep the paintwork clean in order to prevent condensation and mould growth. The use of modern synthetic paints could be a problem since they are typically made to be water-resistant and this may cause the growth of mildew in the Window lock repairs frame.

Most older windows were made of sapwood-rich timber. The timbers will deteriorate quickly when exposed to moist weather conditions, but they can be protected by an extensive preservative treatment prior to when they are used. It is important to choose the appropriate type of wood for the site and climate, as these factors can affect the durability of the joinery. Local window installation cambridge manufacturers make a range of sash made of timber that can be customized to fit specific openings from the past. They are available in the standard Boston pattern or in custom sizes to fit historic structures.

Maintenance

Regular inspections as well as careful redecoration and timely repairs can prolong the lifespan of windows made of timber. The most common cause of decay is moisture intrusion through deteriorated paint and putty. This can be prevented by using a quality wood preservative and thoroughly painting the wood.

Repairs to old sash windows as well as window frames made of casement should be handled with care and minimal disruption. It is possible to repair several traditional designs of timber windows without removing the frame. This should be done as often as is feasible. Loose or peeling paint should be removed with care and lightly sanded to improve the key of the surface and facilitate a better adhesion of the new coating. It is important to avoid stripping old 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 piece of wood has become rotten the best way to proceed is to remove the rotted material and replace it with spliced-in inserts that are shaped to match existing profiles. The inserted wood should also be treated with a wood preserver and the connection between the cill for timber and the sub-cill of the masonry should be sealed.

It's tempting to replace traditional windows with PVC u, particularly when the installer offers an installation that includes both removal and replacement in a single day. It is crucial that installers of replacement windows have a thorough understanding of the history and design of traditional timber frames. This will allow them to make the appropriate suggestions for energy efficiency improvements and other technical improvements that do not alter the historic character of a building. The windows that are replaced should be registered with a Competent Persons Scheme such as FENSA. This will ensure that replacement windows are deemed acceptable by the Building Regulations as a suitable option. A skilled carpenter can put in PVC-u windows that are suited to the original character of the building. This is particularly true where windows are situated in listed buildings or conservation areas.
