Maintaining Timber Windows A well-maintained and maintained timber window is an important element of the historic fabric of a building. It reflects in varying levels, the materials and technologies of the time period it was constructed, as well as the design and craftsmanship. Whenever possible repairs to windows that are already in use should be made in-situ. The repair system that is based on resin can be used to fix the worst areas of decay without removing the entire window. Durability The windows made of timber in many historical structures were designed to last for hundreds of years. But, they have to be maintained to keep them looking great and working properly. The most common maintenance tasks include sash-cord repairs as well as tightening sash pulleys and painting. The demand for upgrading timber windows to increase energy efficiency is also growing. This can include replacing old glazing units, repairing the window rebates that are in place or installing new cills to increase the air seal. A key problem with traditional windows is damage caused by the corrosion of the paintwork. This is particularly true when sash windows are involved as the gaps between the sashes can be extremely large. In these situations water can get into the paint film and cause rotting of the putty as well as the wood underneath. The rotting can be exacerbated due to weather conditions that are poor. To stop this from happening windows, they should be regularly painted with a suitable exterior wood paint. The areas that are damaged should also be repaired using a resin-based product. This will ensure that the best 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 access, as these can admit moisture and cause decay. The structural movement of the wall could also cause distortions in the frame and the sash. This could result in the sash not fitting properly and jamming or sticking to the opening and cracked glazing. This is often corrected by fitting new sash frames made of slow-growing deal (pine), or oak. The cill must be made from a sturdy hardwood, such as oak, in order to prevent any shifting between the new and older work. To alleviate this issue to reduce the risk of this happening, there are several companies that manufacture Boston pattern sash made of wood that can be fitted into most openings. These sash are available in a range of sizes and finishes to meet the needs of today's homeowner. Combined with quadruple draught strips and improved thermal insulation, these new sash can make significant improvements to the energy efficiency of a home. Aesthetics Many old timber frames possess a dazzling aesthetic appeal, since they reflect, in some form, the materials, technology, and architectural taste from the time period they were built. They may have significant historical significance in their own right. This is especially true of windows that were unglazed in the early days of timber-framed structures, where the majority were series of openings within structural frames subdivided horizontally by mullions, and vertically by iron or wood bars in order to protect against invaders. It is crucial to maintain the appearance of traditional wooden window joinery. When you spot any signs of decay due to water penetration, it is important to stop it. It is best to do this with thorough painting, especially where there has been damage or degradation. It is best to use paints that are designed to be used in a system (primer undercoat and finish) and to follow the manufacturer's guidelines for preparation and number coats at each stage. The fungus responsible for wet rot can spread quickly in old windows made of timber. To prevent this from happening, remove any damaged or rotten parts as quickly as you can. The replacement of rotting wood must be done with care using slow grown deal (pine) and, whenever possible it is the same species as which is being removed in order to prevent any movement differences between the new section and existing timbers. In the late period of the 17th century and the middle of the medieval period, glass became cheaper 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 protruding cills. In recent years, glass was fixed to frames that were rebated with glazing sprigs, not lead cames. This method of glazing is not just less susceptible to leaks, but it also allows more expansive and clearer sheets of glass to be used in windows than would have been possible without the need for leaded lights. Energy efficiency Traditional timber windows have an excellent energy performance due to their thickness and multi-layer construction, as well as careful attention to detailing. They also feature large glass areas as well as deep projecting cills that minimise air infiltration. With secondary glazing and draughtproofing the windows can be improved to improve their energy efficiency. It is crucial to remember that these measures need to be considered when it comes to the overall appearance and integrity of the original windows. It makes sense to fix or upgrade windows, rather than replacing them, especially when the improvement in thermal efficiency can be made by simple repairs. Older windows are usually of historical value, as they show a range in technological advancement and changes in the architectural style. The pressures to replace these windows are typically based on the assumption that the windows that are old will need to be replaced in the near future, however the majority of them are capable of providing service for 150, 200 or even 250 years if they are properly maintained. It is essential to understand that the decay issues that are caused by traditional timber windows can be avoided by regular maintenance and swift repairs. In addition it is vital to spot damp penetration issues and fix them promptly to prevent serious damage. Early deterioration of paint is a major problem as it allows moisture to penetrate the wood and cause wet rot. It is not uncommon for this type of damage to go unnoticed until paintwork starts to crack or turn curly. However, it could cause structural damage and further decay. A good quality paint will stop this moisture penetration. To prevent mould and condensation it is essential to keep the paintwork as clean as possible. Modern synthetic paints pose a problem because they are often water-resistant and may cause mildew growth in the window frame. The majority of windows from the past were constructed of sapwood-rich timber. These timbers can deteriorate quickly when exposed to rain, however they can be protected with an extensive preservation treatment prior to use. It is also essential to ensure that the kind of timber used is well-suited to the location and climate conditions, since these factors will influence the durability of the joinery. Local window manufacturers make a variety of timber sash that can be adapted to fit specific openings in historic buildings. They can be constructed according to the standard Boston pattern dimensions, or to custom sizes that fit with the historic architecture. Maintenance The lifespan of windows made of timber can be extended considerably by regular inspection as well as a careful redecoration and prompt repair. The main reason for decay is moisture intrusion through the deterioration of paint and putty. This can be avoided with thorough painting and using an excellent wood preservative. Repairs to sash windows that are old and casement window frames must be done with care and with minimal disruption. It is possible to fix several traditional designs of timber windows without having to remove the frame. This should be done as often as is feasible. Remove peeling or loose paint and lightly sand the surface to improve the 'key” of the surface. This will allow the new coating to adhere better. It is important to avoid removing old paint layers, as they could have historical significance. If a portion of wood is rotting, the best solution is to remove it and replace it with timber inserts designed to match existing profiles. The timber that is inserted should be treated with wood preservative and the junction between masonry sub-cills and timber cill should be sealed. Replacement of traditional windows using PVC-u can be an attractive option, especially when the installer provides a 'one stop shop' installation that handles removal and replacement within the span of a day. RepairMyWindowsAndDoors is crucial that installers of replacement windows are aware of the history and construction of traditional timber frames. This will enable them to make the appropriate recommendations for energy efficiency improvements as well as other technological upgrades that won't harm the character of a historic building. The windows that are replaced should be registered with a Competent Persons Scheme, such as FENSA. This will ensure that the replacement windows are approved as a suitable option under Building Regulations. A skilled carpenter can put in PVC-u windows that conform to the original building's style. This is especially applicable when windows are situated within conservation areas or listed buildings.
