Maintaining Timber Windows

A well-maintained wooden Storefront window Repair is an essential part of a historic building. It illustrates in varying degrees the different materials and technologies, craftsmanship and architectural taste of the time from which it originates.

If it is possible, upvc door repairs must be made in-situ. Repair systems made of resin can be used to fix the most deteriorated areas without removing the entire window.

Durability

The windows made of wood in many historic buildings were made to last for a long time. They do require maintenance to ensure they look good. Maintenance tasks include repairs to sash cables, retightening of pulleys for sash and painting. There is also a rising demand to upgrade timber windows to increase energy efficiency. This could include replacing old glazing units, repairing existing window rebates, or installing new cills for improved air seal.

One of the main issues with traditional windows is the damage caused by corrosion of the paintwork. This is particularly important when windows made of sash are involved because the gaps between sashes can be extremely wide. In these instances water can get into the paint film and cause rotting of the putty and the wood beneath. Poor weather conditions can exacerbate the rotting. To avoid this, windows should be painted regularly using an exterior wood paint that is suitable.

The areas that are damaged should also be repaired using a resin-based product. This will ensure that the maximum possible amount of the original fabric remains. It is also important to limit the number of holes that are drilled into the frame to allow cable entry as these can allow water in and cause decay.

The structural movement of the wall can also lead to distortions in the frame and sash. This can result in sash no longer fitting correctly and jamming or sticking to the opening and cracked glazing. This can often be fixed by the fitting of new sash boxes that have been constructed from slow-growing deal (pine) or oak. The cill must be constructed of a durable hardwood like oak to prevent movement between the existing and new work.

To reduce the risk, there are now a variety of companies that make Boston pattern sash made of wood that will 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. In conjunction with quadruple draught strip and better thermal insulation these new sash can make an enormous difference to the energy efficiency of a house.

Aesthetics

Many old timber frames possess a dazzling aesthetic appeal because they display, in a certain form, the quality of the wood, technology, and architectural aesthetics of the time they were built. They may also have a significant historical significance in their own right. This is particularly true of early windows that were not glazed in timber-framed structures, where the majority of them were series of openings in structural frames that were subdivided horizontally by mullions, and vertically by wood or iron bars in order to keep out intruders.

Traditional window mechnism repair joinery made of timber can be a stunning feature of a building and is essential to maintain its appearance. It is vital that any decay that results from the penetration of moisture should be removed as soon as it is discovered. This can be done by a thorough painting process, especially in areas in which there is already damage or degradation. It is recommended to use paints specifically designed to be used as part of the system (primer as well as undercoat, finish and primer) and follow the manufacturer's instructions in terms of preparation and number of coats required at each stage.

Wet rot is a frequent issue in older timber windows. The best way to stop it developing is to remove any damaged or rotten parts as soon as you can to prevent the spread of the fungus that causes it. The replacement of wood that is rotting must be done with care by using a slow-growing deal (pine) and, whenever possible, the same species as which is being removed to prevent differential movement between the new section and existing timbers.

In the late the 17th and early the medieval periods, glass became less expensive and more abundant, and the openings for glazed glass in timber-framed structures gradually became more sophisticated, with tracery made of wood moulded mullions, moulded mullions, and deep projection cills. The glazing was increasingly laid within rebated frames and secured by 'glazing sprigs' rather than into lead cames. This method of glazing is not only less prone to leaking but it also allows much wider, clearer sheets of glass to be used in the windows than would be possible without the need for leaded lights.

Energy efficiency

Traditional timber windows offer excellent energy efficiency due to their thickness and multi-layer construction, as well as meticulous attention to detail. They also have large glass areas and projecting cills that minimise air infiltration. With secondary glazing and draughtproofing, windows can be made more efficient to increase their energy efficiency. However, it is important to remember that such measures should be evaluated in relation to the overall quality and appearance of the upvc window repairs near me in its original form.

It makes sense to fix or upgrade historic windows rather than replace them, particularly when improvement in thermal efficiency can be made through simple fixes. The windows that are historic have a lot of historical value, as they demonstrate a variety in technical development and changes to architectural taste. The pressures to replace such windows are typically based on the assumption that old windows will need replacement in the near future, however most are still capable of serving for 150, 200 and even 250 years, if properly maintained.

It is essential to understand that the decay issues that are typical of windows made of timber can be avoided by thorough maintenance and timely repairs. It is also essential to recognize damp issues and fix them quickly to avoid major damage. Paint deterioration that occurs early could be a problem as it allows moisture to penetrate into the wood, causing wet rot. This type of damage is typically not evident until the paintwork is damaged or wavy but it can cause severe structural damage, and could lead to further decay.

A good paint will block moisture penetration. To prevent condensation and mould it is essential to keep the paintwork as clean as possible. Modern synthetic paints can pose a problem because they are usually designed to be water-resistant which can lead to the formation of mildew inside the window frame.

The majority of windows from the past were constructed from timber with the majority of sapwood. The timbers will deteriorate rapidly if exposed to rain, however they can be protected with a thorough preservation treatment before use. It is also essential to ensure that the kind of wood used is suited to the site and climate conditions, as these factors can affect the longevity of the joinery. Local window manufacturers make various types of timber sash that can be customized to fit specific openings in historic buildings. They can be made to the standard Boston pattern dimensions or to specific dimensions that are compatible with historic buildings.

Maintenance

Regular inspection, careful redecoration, and timely repairs can prolong the lifespan of windows made of timber. The major cause of decay is the penetration of moisture through the deteriorated paint and putty. This can be avoided by thorough painting and the use of a good quality wood preservative.

It is essential that repairs to old sash and casement windows are well executed and completed with minimal disruption. It is possible to repair the majority of traditional wooden window designs without removing the frame. This should be done whenever possible. Remove any peeling or loose paint and then lightly sand the surface to improve the "key" of the surface. This will allow the new coating to adhere better. Care should be taken to avoid stripping old paint layers which may have historic value If these are present, it is recommended that a study of the paint be carried out.

If a piece of wood is rotting the best way to deal with it is to remove it and replace it with timber inserts designed to match existing profiles. The wood that is being inserted should be treated with wood preservative and the joint between the timber cill and sub-cill of the masonry should be sealed.

It can be tempting to replace traditional windows with PVC U, particularly when the installer provides an 'all-in-one' installation which includes both removal and replacement in a single day. It is essential that the person installing replacement windows has a complete knowledge of the structure and history of traditional wooden frames. This will allow them to make the appropriate recommendations for energy efficiency improvements as well as other technological advancements that won't alter the appearance of a historic building. Anyone who installs cambridge replacement windows windows should be registered with a Competent Persons Scheme such as FENSA. This will ensure that the replacement windows are approved as a suitable solution under Building Regulations. 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 installed in listed buildings or conservation areas.
