Maintaining Timber Windows A well-maintained wooden window is an essential element of a building that is historic. It reflects, in various degree the materials and techniques of the time it was constructed, the design and craftsmanship. If repairs are possible to existing windows are required, they should be carried out in situ. The repair system that is based on resin can be used to repair the most deteriorated areas without removing the entire window. Durability Timber windows were designed to last for hundreds of years. However, they need to be maintained to keep them looking good and operating properly. Maintenance tasks include repairs to sash cords, retightening of sash pulleys and painting. The need to upgrade timber windows in order to increase efficiency in energy use is also growing. This can involve replacing old glazing units, fixing the window rebates that are in place, or installing new cills for improved air sealing. A key problem with traditional windows is the damage caused by the corrosion of the paintwork. This is especially important when it comes to sash windows because the gaps between sashes may be quite large. In these instances, water can penetrate paint film and cause rotting to the putty or wood beneath. The rotting process can be made worse by poor weather conditions. To stop this from happening, windows need to be painted regularly with an exterior wood paint. In addition to repainting, areas that have corroded should be repaired with an adhesive-based repair product. This will ensure that the best possible amount of the original fabric is retained. It is also essential to minimise the number of holes drilled into the frame for cable entry as these can let in water and cause decay. Another issue with older windows is the structural movement within the wall which can cause deformation of the frame and the sash. This can lead to the sash not fitting properly and jamming or sticking into the opening, and broken glass. This can often be fixed by fitting new sash boxes constructed from slow-growing deal (pine) or oak. The cill should be constructed of a durable hardwood like oak to prevent movement between the existing and new work. To reduce the risk to reduce the risk of this happening, there are a variety of companies that make Boston pattern wooden sash that can be fitted into most openings. The sash is available in a variety of sizes and finishes that suit the needs of modern homeowners. Together with quadruple draught strips and improved thermal insulation, these sashes can make a an enormous difference to the energy efficiency of your home. Aesthetics Many old timber windows have a high aesthetic value because they typically show, in a particular way, the materials and technology and architectural taste of the time from which they date. They could have significant historical significance in their own right. upvc repairs near me is especially true of early windows that were not glazed in timber-framed structures, which were just a collection of openings within the frame that were subdivided horizontally into mullions and iron or wood bars to deter intruders. Traditional timber window joinery can be a highly decorative feature of a building and is essential to keep it looking good. It is crucial that any decay resulting from the penetration of moisture should be stopped as soon as it is identified. It is recommended to do this with thorough painting, particularly if there is damage or deterioration. It is recommended to use paints that are specifically designed to be used part of a system (primer undercoat, finish) and to follow the manufacturer's recommendations regarding preparation and the number of coats needed at each stage. Wet rot is a common problem for old timber windows and the best way to stop it becoming a problem is to take out any damaged or rotten sections as soon as possible to stop the spread of the fungus responsible for it. The replacement of rotting wood must be done with care using slow grown deal (pine) and, whenever feasible it is the same species as that which is being removed to prevent differential movement between the new section and existing timbers. In the late medieval and 17th century periods glass became more affordable and abundant, and the openings for glazed glass in timber-framed structures gradually became more sophisticated, with tracery made of wood, moulded mullions and deep projecting cills. In recent times, glass was fixed to rebated frames with glazing sprigs, not lead cames. This method of glazing not only makes windows less likely to leak, but also allows for more clear glass sheets to be used than would have been possible otherwise without the use of lead lights. Energy efficiency The traditional timber windows are energy efficient due to their thickness, multilayer construction and care for particulars. The large glass areas, deep projecting cills and large glazing areas reduce air infiltration. With secondary glazing and draughtproofing, windows can be upgraded to improve their energy efficiency. However, it is important to keep in mind that these measures should be evaluated in relation to the overall integrity and appearance of the window in its original form. It is logical to fix or upgrade windows that are older rather than replacing them, particularly when improvement in thermal efficiency can be achieved through simple repairs. The windows that are historic have a lot of historical value, as they show a range in technological advancement and changes in architectural taste. Most people think that the windows will need to be replaced in the near future. However, they can still provide service for 150, 200, or even 250 years if you take care of maintenance. It is important to recognize that decay issues with traditional timber windows can be preventable by 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 major issue, because it allows moisture to penetrate the wood and cause wet rot. It is not uncommon for this damage to go unnoticed until paintwork starts to crack or turn curly. However, it can cause structural damage and lead to further decay. A high-quality paint will prevent this moisture penetration. It is also important to keep the paintwork in good condition to avoid mould and condensation. Modern synthetic paints can pose a problem because they are usually designed to be water-resistant and this can lead to the formation of mildew in the window frame. The majority of older windows were made from timber that contained the majority of sapwood. These timbers are susceptible to deterioration quickly when exposed to wet weather, however they can be protected with a thorough preservative treatment before they are put to use. It is important to choose the appropriate type of wood for your location and the climate, since these factors can affect the longevity of the joinery. Local window manufacturers have an array of timber sash which can be adapted to fit historical openings. They can be made in the standard Boston pattern or in custom sizes that can be adapted to historical buildings. Maintenance Regular inspection carefully redecorated, as well as prompt repairs can extend the lifespan of windows made of timber. The main reason for the decay is the infiltration of moisture through the deterioration of paint and putty. This can be avoided with careful painting and the use of a good quality wood preservative. Repairs to old sash windows as well as frameless casement windows must be done with care and with minimal disruption. It is possible to repair the majority of traditional wooden window designs without removing the frame. This should be done as often as is feasible. Remove any peeling or loose paint and lightly sand the area to improve the 'key” of the surface. This will allow the new coating to stick better. It is crucial to avoid removing old paint layers, as they may have historical significance. If a piece of wood is rotting the best option is to take it off and replace it with timber inserts designed to match the existing profiles. The inserted timber should also be treated with a wood preservative and the junction between the masonry sub-cill and the timber cill should be sealed. Replacement of traditional windows with PVC-u can be a tempting option, especially when the installer offers a “one-stop shop” installation that handles both removal and replacement within the span of a day. However, it is crucial that the person who installs replacement windows has a full knowledge of the construction and history of traditional timber frames. This will enable them to make appropriate recommendations for energy efficiency improvements and other technological upgrades that do not alter the historic character of a building. Window replacements should be registered with a Competent Persons Scheme such as FENSA. This will ensure the replacements are deemed to be approved under Building Regulations as a suitable option. A skilled carpenter can install PVC-u windows that are suited to the original building's style. This is especially true when windows are situated in listed buildings and conservation areas.
