Maintaining Timber Windows A well-maintained wooden window is an essential component of a historical building. timber casement windows cost cambridge demonstrates in various degrees the materials and technologies design, craftsmanship and aesthetics of the period that it was built in. If it is possible, repairs must be made in-situ. Proprietary resin-based repair systems can be used to fix the worst areas of decay without removing the entire window. Durability The timber windows in many historic structures were designed to last for centuries. They require regular maintenance to keep them looking good. The most frequently-asked maintenance tasks are repairs to sash-cords, re-tightening sash pulleys, and painting. The demand for enhancing timber windows in order to increase efficiency and energy efficiency is also increasing. This can involve replacing old glass units, repairing existing window rebates or putting up new cills to allow for better air sealing. A key problem with traditional windows is the damage caused by corrosion of the paintwork. This is particularly true when sash windows are involved as the gaps between the sashes can be quite wide. In these instances, water can penetrate the paint film and cause rotting of the putty as well as the wood underneath. The rotting can be exacerbated by poor weather conditions. To stop this from happening, windows must be regularly painted 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 the maximum amount of the original fabric is preserved. It is essential to limit the number of holes made into the frame in order to allow cable entry, since they can let in moisture and cause decay. Another major issue with older windows is structural movement in the wall that can cause deformation of the frame and sash. This could result in sash no longer fitting correctly or sticking or jamming into the opening, and damaged glazing. This is often corrected by fitting new sash frames constructed of slow-growing deal (pine) or oak. The cill must be constructed from durable hardwood such as oak to avoid differential movement between the new and existing work. To help reduce this problem, there are now a variety of companies that make Boston pattern sash made of wood that will fit into the majority of existing openings. They are available in various sizes and finishes to fit the needs of modern homeowners. Together with quadruple draught strips and improved thermal insulation, these new sash options can make significant improvements to the energy efficiency of your home. Aesthetics Many old timber windows have a high aesthetic value since they usually demonstrate, in a way, the materials and technology and architectural style of the time in when they were built. They also may have significant historical value in their own right. This is especially true of early unglazed windows in timber-framed buildings, in which the majority were series of openings in structural frames subdivided horizontally by mullions, and vertically by iron or wood bars to protect against invaders. It is essential to preserve the appearance of traditional timber window joinery. When you spot any decay caused by water penetration it is essential to stop it. This is best accomplished by painting thoroughly, especially in areas in which there is already damage or degradation. It is recommended to use paints that are designed to be used in a set (primer undercoat and finish) and to adhere to the manufacturer's recommendations for preparation and number coats at each stage. The fungus responsible for wet rot is able to spread quickly in old windows made of wood. To prevent this, remove any damaged or rotten parts as quickly as you can. Replace rotting wood with slow-grown deal (pine), and if possible, the same kind of timber that is being removed, to prevent any differential movement. Glass became more affordable and abundant during the late medieval period and into the 17th century. This led to glazed openings on timber-framed houses became more complex with moulded mullions, tracery made of wood and deep projecting cills. In recent times, glass was pinned into frames that were rebated with glazing sprigs rather than lead cames. This method of glazing not only makes the windows less likely to leak and break, but also allows more clear glass sheets to be utilized than would have been possible otherwise without the use of lead lights. Energy efficiency The traditional timber windows are energy efficient because of their thickness and multilayer construction as well as care for the smallest of details. They also feature large glass areas as well as deep projection cills which reduce air infiltration. With secondary glazing and draughtproofing, windows can be made more efficient to improve their energy efficiency. It is essential to remember that these measures must be taken into consideration in relation to the overall integrity and appearance of the original windows. So, retaining existing historic windows that require repair rather than replacing them is sensible especially when their thermal enhancements can be achieved cost-effectively through simple repairs and upgrades. Historic windows often have a historical value that shows a variety of technological advancement and changes in architectural tastes. The pressures to replace these windows are typically based on the assumption that windows that are old will need to be replaced in the near future, but they are in a position to last for 150, 200 and even 250 years if properly maintained. It is important to recognize that decay issues associated in traditional timber windows are easily prevented with timely and thorough repairs. In addition, it is essential to recognize damp penetration issues and fix them promptly to avoid major damage. Early paint deterioration is a particular problem, because it allows moisture to penetrate the wood and cause wet rot. It is not uncommon for this damage to go unnoticed until the paintwork begins to crack or become curly. However, it can cause structural damage and then further decay. A high-quality paint will prevent this moisture penetration. It is also important to keep the paintwork clean to avoid mould and condensation. Modern synthetic paints pose a challenge because they are water-resistant and can cause mildew growth in the window frame. The majority of windows from the past were constructed of sapwood-rich timber. These timbers deteriorate quickly if exposed to rain, however they can be protected with a thorough preservation treatment before use. It is crucial to select the right kind of wood for the site and climate, as these factors will affect the durability of the joinery. Local window manufacturers produce various types of timber sash that can be tailored to fit specific historic openings. They can be made to the standard Boston pattern dimensions or to specific sizes that are in keeping with the historic architecture. Maintenance The lifespan of windows made of timber can be extended significantly through regular inspections as well as a careful redecoration and timely repair. The major cause of decay is moisture leaking through the deteriorated paint and putty. This can be avoided with thorough painting and the use of high-quality wood preservative. It is crucial that repairs to the old sash and casement windows are done correctly, and carried out with the minimum disturbance. It is possible to repair several traditional designs of timber windows without taking the frame off. This should be done whenever possible. Paint that is peeling or loose should be removed with care and lightly sanded to improve the key of the surface, allowing for a better adhesion of the new coating. It is important to avoid removing old paint layers that could have historical significance. When a piece of wood has become rotten the best way to proceed is to take out the rotten material and replace it with spliced-in inserts that are shaped to match existing profiles. The timber inserts should be treated using wood preservative. The junction between the masonry sub-cill and the timber cill should be sealed. It's tempting to replace traditional windows with PVC u, especially when the installer provides an installation that includes both replacement and removal within a single day. It is crucial that installers of replacement windows are aware of the history and construction of traditional timber frames. This will allow them to make the right suggestions for improvements to energy efficiency and other technical improvements that will not harm the historical character of a building. Those providing replacement 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. It is, of course, possible for an experienced and skilled carpenter to install PVC-U windows that fit the character of the building originally. This is particularly true where the windows are located in listed buildings and conservation areas.
