Maintaining Timber Windows A well-maintained wooden window is an essential part of a historic building. It demonstrates in various degrees the materials and technologies design, craftsmanship and aesthetics of the time period that it was built in. When possible, repairs should be made in-situ. Repairing the most deteriorated areas of decay is possible using proprietary resin-based systems. Durability Timber windows were made to last hundreds of years. However, they do need to be maintained to ensure they look good and functioning correctly. The most common maintenance tasks include sash-cord repairs and re-tightening the sash pulleys and painting. The demand for enhancing windows made of timber to improve efficiency and energy efficiency is also increasing. This may include replacing old glazing units, repairing existing window rebates, or installing new cills to increase the air seal. The corrosion of paintwork is a major issue with traditional windows. This is particularly important when windows with sash are involved since the gaps between the sashes can be quite large. In these instances water may get through the paint film and cause rotting of the putty as well as the wood underneath. Weather conditions that are not ideal can accelerate the rotting. To stop this from happening windows from becoming rotten, they must be painted regularly using a suitable exterior wood paint. The areas that are damaged should also be repaired using resin-based products. This will ensure that the maximum possible amount of the original fabric is retained. It is important to minimize the number of holes that are created into the frame to allow cable entry because they could let in moisture and cause decay. The structural movement of the wall could also cause distortions in the frame and sash. This could result in sash no longer fitting correctly or sticking or jamming into the opening, and damaged glazing. Most often, this is corrected by fitting new sash boxes constructed from slow-growing deal (pine) or oak. The cill should be made of a durable hardwood like oak to avoid any movement between the new and existing work. There are several companies that manufacture Boston pattern wooden sash to fit into the majority of existing openings. They are available in a variety of sizes and finishes that will fit the needs of modern-day homeowners. The new sash, combined with quadruple draft strips and improved thermal insulation can make a significant difference to the energy-efficiency of a home. Aesthetics Many old timber windows have a high aesthetic value as they often demonstrate, in a way, the materials and technology and architectural style of the time from when they were built. They may have significant historical value on their own. This is especially true of early unglazed windows in timber-framed buildings, where the majority of them were series of openings within structural frames subdivided horizontally by mullions and vertical iron or wood bars to protect against intrusions. Traditional window joinery made of timber can be a highly decorative element of a structure and is essential to maintain its appearance. It is crucial that any decay resulting from moisture penetration should be removed as soon as it is identified. This is best accomplished by applying a thorough coat of paint, particularly in areas where there has already been damage or degradation. It is recommended to use paints designed to be used in a system (primer undercoat and finish), and to follow the manufacturer's guidelines for preparation and number of coats at each stage. The fungus responsible for wet rot can spread quickly in old timber windows. To stop this from happening, take out any damaged or rotten components as promptly as you are able to. Replace the wood that is rotting with slow-growing deal (pine) and, when possible, the exact type of timber as the one that is being removed to prevent the possibility of differential movement. In the late medieval and 17th century periods glass became more affordable and plentiful so that glazed openings in timber-framed buildings gradually became more sophisticated, with tracery made of wood as well as moulded mullions and protruding cills. In recent times, glass was fixed to rebated frames with glazing sprigs, not lead cames. This method of glazing is not just less susceptible to leaks, but it can allow for more expansive and clearer sheets of glass to be used in windows than would otherwise be possible without the need for leaded lights. Energy efficiency Traditional timber windows provide a good energy performance due to their thickness, multi-layer construction and very meticulous attention to detail. The large glass areas, the deep projecting cills and large glazing areas reduce air infiltration. The windows can be modified to improve their energy efficiency with draught-proofing and secondary glazing. However it is essential to remember that such measures should be evaluated in terms of the overall appearance and integrity of the window in its original form. Therefore, keeping the existing windows from the past that require repair instead of replacing them is logical particularly when thermal enhancements can be made economically through simple repairs and upgrades. Historic windows are often of historical significance, since they demonstrate a variety in technological advancements and changes to architectural taste. The pressures to replace such windows are generally based on the assumption that the old windows will need replacement in the near future, but the majority of them are in a position to last for 150, 200 and even 250 years, if properly maintained. It is essential to realize that decay issues with traditional timber windows are easily prevented with timely and thorough repairs. It is also crucial to recognize damp issues and fix them quickly so that you can avoid serious damage. Early deterioration of paint is a major problem because it allows moisture to penetrate the wood and cause wet rot. This type of damage is typically not apparent until the paintwork becomes cracking or wavy but it can cause severe structural damage and can lead to further decay. A good paint will block moisture penetration. It is also essential to keep the paintwork in good condition to avoid mould and condensation. Modern synthetic paints can be problematic because they are usually made to be water-resistant and this can lead to the formation of mildew in the window frame. Most older windows were made from sapwood-rich timber. These timbers can deteriorate quickly when exposed to rain, however they can be preserved with a thorough preservation treatment before use. It is essential to select the appropriate type of wood for the site and the climate, since these factors will affect the durability of the joinery. Local window manufacturers create a variety of timber sash that can be tailored to fit specific openings in historic buildings. They can be constructed according to the standard Boston pattern dimensions or to custom dimensions that are compatible with historic buildings. Maintenance Regular inspections as well as careful redecoration and timely repairs can prolong the life of timber windows. The main cause of decay is moisture leaking through the deteriorated paint and putty. upvc door handle repairs near me Repair My Windows And Doors can be prevented by thorough painting and using an excellent wood preservative. It is important that repairs to the old sash and casement windows are properly executed, and carried out without causing any disturbance. It is possible to fix several traditional designs of timber windows without having to remove the frame. This is a must whenever it is possible. Paint that is peeling or loose must be removed with care and sanded lightly to improve the 'key' of the surface and facilitate an easier adhesion of the new coating. Care should be taken to avoid stripping old paint layers that might have historical significance If these are present it is recommended that a paint analysis be conducted. If a piece of timber has begun to decay, the best way to proceed is to eliminate the rotten material and replace it with spliced-in timber inserts that are shaped to match the existing profiles. The wood that is inserted should be treated with wood preservative and the connection between the cill for timber and the masonry sub-cill should be sealed. Replacement of traditional windows with PVC-u is a tempting option, especially when the installer provides a “one-stop shop” installation service that can handle removal and replacement in the span of a day. It is important that the installers of replacement windows have a thorough understanding of the history and construction of traditional timber frames. This will allow them to make appropriate recommendations for energy efficiency improvements and other technological upgrades that won't harm the character 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 approved as a suitable solution in accordance with Building Regulations. A skilled carpenter is able to install PVC-u Windows that are sympathetic to the original character of the building. This is especially true when the windows are located in listed buildings and conservation areas.
