Maintaining Timber Windows A well-maintained timber window is a significant element of the historic structure of a building. It reflects, in various degrees, the materials and technologies of the time it was made, the craftsmanship and architectural taste. If repairs are possible to existing windows are required, they should be carried out in-situ. Repairing the most severe areas of decay is possible using proprietary resin-based systems. Durability Timber windows were designed to last for hundreds of years. They require regular maintenance to ensure they look good. Maintenance tasks include repairs to sash cords, retightening of sash pulleys and painting. The need to upgrade timber windows in order to improve energy efficiency is also growing. This may include replacing old glazing units, fixing existing window rebates, or installing new cills to improve air seal. A key problem with traditional windows is damage caused by corrosion of the paintwork. This is especially important where windows with sash are involved since the gaps between sashes can be quite large. In these situations water can enter the paint film and cause rotting of the putty or wood beneath. The rotting process can be made worse by poor weather conditions. To prevent this, windows should be regularly painted with an exterior wood paint that is suitable. Corroded areas should also be repaired using a resin-based product. This will ensure that the maximum possible amount of the original fabric is retained. It is also necessary to limit the number of holes you drill into the frame for cable entry, as they could admit water and lead to decay. Another significant problem with older windows is the structural movement within the wall which can cause deformation of the frame and the sash. This could result in the sash not fitting properly or sticking or jamming into the opening, and damaged glazing. This can be fixed frequently by fitting new sash frames constructed of slow-growing deal (pine), or oak. The cill needs to be constructed of a strong hardwood such as oak, to avoid the movement of new and existing work. To alleviate this issue There are a variety of companies that manufacture Boston pattern wooden sash that will fit most existing openings. These sash come in various sizes and finishes to meet the requirements 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 A lot of old timber frames have a great aesthetic appeal, as they reflect, in some shape, the materials technology, the construction process, and the architectural aesthetics of the time they were constructed. They could have significant historical value on their own. This is especially true for early windows that were not glazed in timber-framed buildings, where the great majority were merely a series of openings within the frame, which were divided horizontally into mullions and vertical iron or wood bars to deter intruders. Traditional window joinery made of timber can be a stunning element of a structure and is crucial to keep its appearance. It is crucial that any decay that results from water penetration is removed as soon as it is identified. This is best done by a thorough painting process, especially in areas where there has already been damage or degradation. It is best to use paints 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. 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 you can to stop the spread of the fungus responsible for it. Replace rotting wood with slow-growing deal (pine), and should it be possible, the same type of timber as the one that is being removed, to avoid differential movement. In the late medieval and 17th century periods glass became more affordable and abundant, so that the glazed openings in timber-framed structures gradually became more sophisticated, with tracery made of wood moulded mullions, moulded mullions, and deep protruding cills. In recent times, glass was fixed to frames that were rebated with glazing sprigs instead of lead cames. This method of glazing is not just less prone to leaks but also allows for larger, clearer sheets of glass to be used in the windows than would be possible without the need for leaded lights. Energy efficiency Traditional timber windows are energy efficient due to their thickness and multilayer construction, as well as their focus on particulars. The large glass surfaces, the deep projecting cills, and the large glazing areas minimize air infiltration. With secondary glazing and draught proofing, the windows can be improved to improve their energy efficiency. However, it is important to remember that such measures should be evaluated in terms of the overall appearance and integrity of the original window. It is sensible to repair or upgrade existing windows that are older rather than replacing them, particularly when improvements in thermal efficiency can be achieved by simple repairs. Older windows typically have an historic value that demonstrates a range of technological advances and changes in architectural style. Many people believe that these windows will have to be replaced in the near future. However, they will last for 150, 200, or even 250 years with proper maintenance. It is important to recognize that decay problems with traditional timber windows can be easily prevented with timely and thorough repairs. In addition it is crucial to recognize damp penetration issues and to remedy them quickly to avoid major damage. Early deterioration of paint is a major issue, because it allows moisture to penetrate the wood and cause wet rot. This damage is often not evident until the paintwork becomes wavy or cracked but it can cause severe structural damage and lead to further decay. A good quality paint will stop this moisture penetration. It is also necessary to keep the paintwork in good condition in order to prevent condensation and the growth of mould. Modern synthetic paints are problematic since they are usually water-resistant and can cause mildew growth in the window frame. The majority of older windows were constructed of sapwood-rich timber. The timbers will deteriorate quickly when exposed to moist weather, however they can be protected by a thorough preservative treatment before they are put to use. It is essential to select the right type of wood for your location and climate, as these factors can affect the longevity of the joinery. Local window manufacturers have various types of sash made from timber that can be made to fit the historic openings. They can be made in the standard Boston pattern or in custom sizes that can be adapted to the architectural style of historic structures. Maintenance Regular inspection, careful redecoration, and prompt repairs can extend the life of timber windows. The main cause of decay is the penetration of moisture through deteriorated paint and putty. This can be prevented by careful painting and using a good quality wood preservative. It is important that repairs to old sash and casement windows are well executed, and carried out with minimal disruption. repairmywindowsanddoors of the traditional designs for timber windows can be repaired without dismantling the frame, and this method should be taken whenever possible. Paint that is peeling or loose must be removed with care and sanded lightly to increase the key of the surface and facilitate a better adhesion of the new coating. It is important to avoid stripping old paint layers which could have historical value and if they are present, it is recommended that a paint analysis be carried out. If a portion of wood is decayed the best option is to remove it and replace it with timber inserts designed to match existing profiles. The wood that is inserted should be treated with a wood preservative, and the junction between the timber cill and the sub-cill of the masonry should be sealed. It is tempting to replace traditional windows with PVC U, particularly when the installer offers an installation that includes both removal and replacement within a single day. It is important that the installers of replacement windows are aware of the history and construction of traditional timber frames. This will allow them to make the appropriate suggestions for energy efficiency improvements and other technological upgrades that won't alter the appearance of a building that is historic. The window installers who provide replacement windows must be registered with a Competent Persons Scheme like FENSA. This will ensure that the replacements are deemed as a suitable solution in accordance with Building Regulations. A skilled carpenter is able to install PVC-u windows that conform to original building's character. This is especially true when windows are installed in listed buildings and conservation areas.
