Maintaining Timber Windows

A well-maintained window made of timber is a crucial part of the historic fabric of a building. It is a representation of the various materials and techniques, craftsmanship and architectural taste of the time period that it was built in.

If possible, repairs should be done in-situ. Repair systems made of resin can be used to repair the worst areas of decay without having to remove the entire window.

Durability

The timber windows in many old structures were designed to last for a long time. But, they have to be maintained to ensure they look good and functioning correctly. The most frequent maintenance tasks include upvc door repairs to sash cords and re-tightening the sash pulleys and painting. There is a growing need to upgrade the timber windows to increase the efficiency of energy. This can involve replacing old glass units, repairing the window rebates that are in place, or installing new cills that allow for improved air sealing.

A key problem with traditional windows is damage caused by corrosion of the paintwork. This is particularly true when windows with sash are involved since the gaps between sashes can be very large. In these situations, water can penetrate paint film and cause rotting of the wood or putty underneath. The weather can be a factor in accelerating the rotting. To prevent this windows, they should be painted regularly using an exterior wood paint that is suitable.

Corroded areas should be repaired with a resin-based product. This will ensure that the highest possible amount of the original fabric is preserved. It is also essential to reduce the number of holes that are drilled into the frame to allow cable entry since these could allow water in and cause decay.

Another major issue with older windows is structural movement in the wall which can lead to deformation of the frame and sash. This could result in the sash fitting incorrectly and jamming or sticking into the opening, or breaking glass. This can be corrected often by fitting new frames for sash made of slow-grown deal (pine), or oak. The cill must be constructed of a durable hardwood like oak to prevent movement between the new and existing work.

There are several companies that produce Boston pattern wooden sash to fit in with the majority of openings. They are available in various sizes and finishes to meet the requirements of modern homeowners. Combined with quadruple draught strips and a better thermal insulation, these sashes can make a a substantial difference to the energy efficiency of a home.

Aesthetics

Many old timber windows have a great aesthetic value since they usually illustrate, in some way, the materials and technology and architectural style of the time in which they originate. They could have significant historical significance on their own. This is especially true for early unglazed window openings in timber-framed buildings, where the great majority were just a collection of openings within the frame, which were divided horizontally into mullions and wood or iron bars to keep out intrusions.

It is crucial to maintain the appearance of traditional timber window joinery. As soon as you see any decay caused by water penetration, it is important to stop it. This is best done by applying a thorough coat of paint, particularly in areas that have already suffered damage or deterioration. 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 guidelines for preparation and number of coats at each stage.

Wet rot is a common issue in older timber windows. The best method to stop it from growing is to eliminate any damaged or rotten parts as soon as possible to prevent the spread of the fungus responsible for it. Replace the wood that is rotting with slow-growing deal (pine), and if possible, the same type of wood as the one that is being removed to prevent the possibility of differential movement.

In the late the 17th and early the medieval periods, glass became more affordable and plentiful so that glazed openings in timber-framed structures gradually became more sophisticated, with tracery made of wood, moulded mullions and deep protruding cills. In recent years, glass was fixed to frames that were rebated using glazing sprigs, not lead cames. This method of glazing is not only less prone to leaking but it also allows larger and clearer sheets of glass to be used in the windows than would otherwise have been 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. The large glass areas, the deep projecting cills, and the large double glazing seal repairs [Read the Full Report] areas help to reduce air infiltration. The windows can be modified to increase their energy efficiency through draughtproofing and secondary glazing. However it is crucial to keep in mind that any such measures should be evaluated in terms of the overall integrity and appearance of the original window.

So, retaining the existing windows from the past that require repair instead of replacing them is logical, particularly when their thermal improvements can be achieved cost-effectively through simple repairs and improvements. Older windows are usually of historical value, as they demonstrate a variety in technological advancements and changes to architectural style. Most people assume that the windows will need to be replaced in the near future. However, they can still provide service for 150,200, and even 250 years if you take care of maintenance.

It is crucial to recognize that the decay issues that are associated with traditional windows made of timber can be avoided by thorough maintenance and prompt repairs. Additionally it is crucial to spot damp penetration issues and address them swiftly to prevent serious damage. Early paint deterioration could be a problem as it allows moisture to get into the wood, causing wet rot. It is not uncommon for this issue to go unnoticed until paintwork starts to crack or turn wavier. However, it can cause structural damage and lead to further decay.

A good quality paint will prevent this moisture penetration. To prevent condensation and mould it is crucial to keep the paintwork as clean as it can be. The use of modern synthetic paints could be a problem, as they are often made to be water-resistant which can result in the formation of mildew in the window frame.

Most older windows were made of sapwood-rich timber. The timbers will deteriorate quickly when exposed to wet weather, however they can be protected by a thorough treatment of preservative before they are used. It is important to choose the right kind of wood for your location and climate, as these factors will affect the durability of the joinery.

Maintenance

The life of timber windows can be extended significantly through regular inspections, careful redecoration and timely repair.

Be careful to avoid stripping old paint layers that may have historic value and if they are present, it is recommended that a study of the paint be carried out.

If a piece of wood has rotted the best way to deal with it is to remove it and replace it with timber inserts that are shaped to match existing profiles. The timber inserts should be treated with a wood preservative. The junction between the masonry sub-cill and the timber cill should be sealed.

Replacement of windows made of traditional PVC-u may be an appealing option, particularly when the installer offers a 'one stop shop' installation service that can handle removal and replacement windows cambridge within a day. It is crucial that installers of replacement windows are aware of the history and construction of traditional timber frames.

The window installers who provide replacement windows must be registered with a Competent Persons Scheme such as FENSA. This will ensure that replacement windows are deemed acceptable in accordance with Building Regulations as a suitable option. A skilled carpenter can put in PVC-u windows that are suited to the original building's style. This is especially relevant when windows are situated within listed buildings or conservation areas.
