Maintaining Timber Windows

A well-maintained wooden windows cambridge window is an essential component of a historical building. It demonstrates in various degrees the different materials and technologies, craftsmanship and architectural taste of the time from which it originates.

If it is possible, repairs must be made in-situ. Repairing the most severe areas of decay can be done by using specialized resin-based systems.

Durability

The windows made of timber in many historic structures were designed to last for a long time. However, they need to be maintained to ensure they look good and functioning correctly. The most frequent maintenance tasks are repairs to sash-cords as well as tightening sash pulleys and painting. The demand for enhancing timber windows in order to increase efficiency in energy use is also growing. This could mean replacing old glazing units, fixing the window rebates that are in place, or installing new cills to allow for improved air sealing.

The deterioration of paintwork is a major issue with traditional windows. This is especially true in the case of sash windows as the gaps between sashes can be very large. In these circumstances water may get through the paint film and cause rotting of the putty as well as underlying wood. The rotting can be exacerbated by weather conditions that are not ideal. To stop this from happening, windows must be painted regularly with an exterior wood paint.

In addition to repainting, corroded areas must be repaired using the help of a resin-based upvc Door Repair solution. This will ensure the maximum amount of original fabric preserved. It is also important to minimise the number of holes you drill 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 could cause deformation of the frame and the sash. This can result in the sash fitting incorrectly and jamming or sticking into the opening, and even broken glass. This can often be fixed by fitting new sash boxes that have been made from slow grown deal (pine) or oak. The cill must be made of a durable hardwood, like oak, to prevent the movement of new and existing work.

There are several companies that produce Boston pattern wooden sash to fit into the majority of existing openings. The sash is available in various sizes and finishes that will suit the needs of modern-day homeowners. Together with quadruple draught strips and better thermal insulation these new sash options can make a substantial difference to the energy efficiency of a house.

Aesthetics

A lot of old timber frames have a high aesthetic appeal because they show, in some form, the quality of the wood technology, the construction process, and the architectural taste from the time period they were constructed. They could have significant historical significance in their own right. This is particularly true of windows that were unglazed in the early days of timber-framed buildings, where the great majority were just a collection of openings within the structural frame sub-divided horizontally into mullions and vertical iron or wood bars to deter invaders.

Traditional window joinery made from timber can be a stunning feature of a building and it is important to keep it looking good. It is vital that any decay that results from water penetration is removed as soon as it is discovered. This is best done by painting thoroughly, especially in areas in which there is already damage or deterioration. It is recommended to use paints specifically designed to be used part of the system (primer undercoat, finish) and follow the manufacturer's instructions in relation to preparation and number of coats required at each stage.

The fungus responsible for wet rot can spread quickly in old windows made of wood. To stop this from happening, take out any rotten or damaged parts as promptly as you are able to. The replacement of wood that is rotting should be carefully undertaken with a slow-growing deal (pine) and, wherever feasible, the same species as which is being removed to avoid any movement differences between the new and old timbers.

In the late period of the 17th century and the middle of the medieval period, glass became cheaper and more abundant, so that the glazed openings in timber-framed buildings gradually became more elegant with wooden tracery moulded mullions, moulded mullions, and deep protruding cills. The glazing was increasingly set within rebated frames and pinned in with 'glazing sprigs', rather than into lead cames. This method of glazing is not just less susceptible to leaks, but it can allow for much wider and clearer sheets of glass to be used in the windows than would otherwise be possible without the need for leaded lights.

Energy efficiency

Traditional timber windows are energy efficient due to their thickness, multilayer construction and care for particulars. They also have large glass areas as well as deep projecting cills that minimise air infiltration. The windows can be modified to improve their energy efficiency through draughtproofing and secondary glazing. However, it is important to remember that such measures should be evaluated in relation to the overall quality and appearance of the window in its original form.

It is sensible to repair or upgrade existing windows, rather than replacing them, particularly when improvements in thermal efficiency can be achieved through simple fixes. Older windows are usually considered to be of historical value because they demonstrate a variety in technological advancement and changes in the architectural style. The pressure to replace these windows are usually based on the assumption that the windows of the past will require replacement in the near future, but most are still capable of serving for 150, 200 and even 250 years, if properly maintained.

It is important to recognise that the decay issues that are that are typical of timber windows can be avoided by regular maintenance and timely repairs. It is also essential to identify damp problems and fix them quickly so that you can avoid serious damage. Early deterioration of paint is a particular problem, because it allows moisture to penetrate the wood and cause wet rot. It is not uncommon for this type of damage to go undetected until the paintwork begins to crack or become curly. However, it could cause structural damage and further decay.

A good quality paint will stop this moisture penetration. To prevent condensation and mould it is essential to keep the paintwork as clean as it can be. The use of modern synthetic paints can pose a problem, as they are often made to be water-resistant and this may cause the growth of mildew within the window frame.

The majority of windows from the past were made from timber that contained the majority 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 also crucial to ensure that the kind of wood used is suited to the site and climate conditions, as these elements can affect the longevity of the joinery. Local window manufacturers provide various types of timber sash which can be customized to fit historic openings. They are available in the standard Boston pattern or in custom sizes to suit historic structures.

Maintenance

The lifespan of windows made of timber can be extended through regular inspections carefully redecoration, and timely ventilation repair cambridgeshire. The major cause of decay is moisture penetration through deteriorated paint and putty. This can be avoided by using a high-quality wood preservative and painting the wood thoroughly.

Repairs to sash windows that are old and frameless casement windows should be handled with care and with the least amount of disruption. It is possible to repair the majority of traditional wooden plastic window repair designs without removing the frame. This should be done as often as is feasible. Peeling or loose paint should be removed carefully and sanded lightly to improve the "key" of the surface, allowing for an easier adhesion of the new coating. It is essential to not remove old paint layers, as they may have historical value.

If a piece of wood is rotting, the best solution is to remove it and replace it with timber inserts designed to match the existing profiles. The timber that is inserted should be treated with wood preservative. The junction between the masonry sub-cill and the timber cill should be sealed.

Replacement of traditional windows with PVC-u is 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 important that the installers of replacement windows have a deep understanding of the history and construction of traditional timber frames. This will enable them to make the appropriate recommendations for energy efficiency improvements and other technical improvements that do not alter the historic character of a building. upvc window and door repairs replacements 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 quite possible for an experienced and skilled carpenter to install PVC-U windows that are sympathetic to the style of the building originally. This is particularly true when the windows are located within conservation areas or listed buildings.
