It's Time To Extend Your Cambridge Window Options
Maintaining Timber Windows A well-maintained and maintained timber window is a crucial element of the historic fabric of a building. It is a representation of the materials and technologies, craftsmanship and architectural taste of the period from which it dates. If repairs are possible to existing windows are required, they should be made in situ. The repair system that is based on resin can be used to repair the most deteriorated areas without removing the whole window. Durability The timber windows in many old buildings were made to last for a long time. They do require some maintenance to keep them looking good. The most frequent maintenance tasks include sash-cord repairs as well as tightening sash pulleys and painting. There is also a rising demand to upgrade the timber windows to improve energy efficiency. This could mean replacing old glazing units, fixing existing window rebates or putting in new cills that allow for improved air sealing. The corrosion of paintwork is a major issue with traditional windows. This is particularly important when it comes to sash windows as the gaps between sashes can be quite large. In these instances water can get into the paint film and cause decay of the putty and underlying wood. The rotting may be further aggravated by poor weather conditions. To stop this from happening, windows need to be regularly painted with an exterior wood paint. In addition to repainting, areas that have corroded must be repaired using an adhesive-based repair product. This will ensure that the maximum possible amount of the original fabric is preserved. It is also necessary to limit the number of holes you drill into the frame to allow cable entry since these could let in water and cause decay. Another major issue with older windows is the structural movement within the wall that can cause deformation of the frame and the sash. This can result in sash no longer fitting correctly or sticking or jamming into the opening, and damaged glazing. Often this can be corrected by fitting new sash boxes constructed from slow-growing deal (pine) or oak. The cill should be made from a sturdy hardwood such as oak to avoid any movement between the old and new work. There are now several companies that manufacture Boston pattern wooden sash that fit in with the majority of openings. These sash are available in a variety of sizes and finishes that meet the needs of today's homeowner. The new sash, combined with quadruple draft strip and a better thermal insulation, can make a huge difference to the efficiency of a home's energy use. Aesthetics Many old wooden windows have an excellent aesthetic value as they often demonstrate, in a way the materials and techniques and architectural style of the time from which they date. They may also have significant historical value in their in their own right. This is especially true of windows that were unglazed in the early days of timber-framed buildings, where the majority of them were series of openings in structural frames that were subdivided horizontally by mullions with vertical iron or wood bars in order to protect against intruders. It is essential to preserve the appearance of traditional wooden window joinery. As soon as you see any signs of decay caused by the penetration of moisture it is essential to stop it. This is best done by painting thoroughly, especially in areas that have already suffered damage or deterioration. It is best to use paints that are designed to be used in a system (primer undercoat and finish) and follow the manufacturer’s recommendations for preparation and number of coats at each stage. Wet rot is a frequent issue in old timber windows. The best way to stop it growing is to eliminate sections that are damaged or rotten immediately to stop the spread of the fungus that causes it. The replacement of wood that is rotting must be done with care with a slow-growing deal (pine) and, if feasible, the same species as which is being removed to prevent differential movement between the new section and existing timbers. Glass became more affordable and abundant in the late medieval period and into the 17th century. As a result, glazed openings on timber-framed houses became more complicated with moulded mullions and traceries, made of wood and deep projecting cills. In recent years, glass was fixed to frames that were rebated using glazing sprigs, not lead cames. This method of glazing is not just less susceptible to leaks, but also allows for more expansive and clearer sheets of glass to be used in the windows than would have been possible without the need for leaded lights. repairmywindowsanddoors.co.uk offer excellent energy efficiency due to their thickness and multi-layer construction, as well as careful attention to detailing. The large glass surfaces, the deep projecting cills, and the large glazing areas minimize air infiltration. With secondary glazing and draughtproofing, the windows can be improved to increase their energy efficiency. However it is essential to keep in mind that any such measures must be considered in terms of the overall integrity and appearance of the original window. It is logical to repair or upgrade existing windows, rather than replacing them, particularly when improvement in energy efficiency can be made through simple repairs. The windows that are historic have a lot of historical value, as they reflect a variety of technological advancement and changes in the architectural style. Many people believe that these windows will need to be replaced in the near future. However, most can still provide service for 150,200, and even 250 years if they are maintained with proper maintenance. It is crucial to recognize that the decay issues that are typical of timber windows can be prevented by thorough maintenance and swift repairs. Additionally it is vital to identify damp penetration problems and to remedy them quickly to avoid serious damage. Early paint deterioration can be a problem because it allows moisture to get into the wood, leading to wet rot. It is not uncommon for this damage to go undetected until the paintwork begins to crack or become wavy. However, it can cause structural damage and then further decay. A good quality paint will stop this moisture from entering. It is also important to keep the paintwork spotless to avoid mould and condensation. Modern synthetic paints pose a problem because they are often water-resistant, and can cause mildew to develop in the window frame. The majority of windows from the past were constructed from timber with a high proportion of sapwood. These timbers deteriorate quickly if exposed to rain, but they can be protected with an extensive preservation treatment prior to use. It is essential to select the right kind of wood for the site and climate, as these factors can affect the longevity of the joinery. Local window manufacturers create a variety of timber sash that can be customized to fit specific openings in historic buildings. They can be made in the standard Boston pattern or in custom sizes to fit historic buildings. Maintenance The life of timber windows can be extended through regular inspections as well as a careful redecoration and timely repair. The most common reason for the decay is the infiltration of moisture through the deterioration of paint and putty. This can be avoided by thorough painting and using a good quality wood preservative. It is important that repairs to old sash or casement windows are done correctly, and carried out with minimal disruption. It is possible to repair several traditional designs of timber windows without removing the frame. This should be done as often as is feasible. Remove peeling or loose paint and then lightly sand the surface 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 value. When a piece of wood is rotten, the best option is to remove the rotted material and replace it with spliced-in inserts that are shaped to match existing profiles. The wood that is being inserted should be treated with wood preservative, and the junction between the timber cill and masonry sub-cill should be sealed. Replacement of windows made of traditional PVC-u may be an appealing option, particularly when the installer provides a 'one stop shop' installation that takes care of both removal and replacement within a day. It is, however, crucial that the person who installs replacement windows has a full knowledge of the construction and history of traditional wooden frames. This will allow them to make the appropriate recommendations for energy efficiency improvements and other technical upgrades that won't harm the historic character of a building. Those who provide replacement windows must be registered under a Competent Persons Scheme such as FENSA. This will ensure the replacements are deemed to be approved in accordance with Building Regulations as a suitable option. A skilled carpenter is able to install PVC-u windows that conform to the original character of the building. This is especially true where windows are installed in listed buildings or conservation areas.
