Maintaining Timber Windows

A well-maintained and maintained timber upvc window and door repairs is a crucial part of the historic fabric of a building. It reflects in different degree the materials and technologies of the time it was constructed, as well as the architectural style and craftsmanship.

If possible, repairs should be made on-site. Proprietary resin-based repair systems can be used to fix the worst areas of decay without having to remove the entire window.

Durability

Timber windows were made to last for hundreds of years. They do require some maintenance to ensure they look good. Maintenance tasks include repairs to sash cords and retightening pulleys on sash, and painting. The demand for upgrading timber windows in order to increase efficiency in energy use is also growing. This can include replacing old glazing units, fixing the window doctor cambridge rebates that are in place or installing new cills to increase the air seal.

One of the main issues with traditional windows is the damage caused by corrosion of the paintwork. This is especially important where sash windows are involved as the gaps between the sashes can be quite wide. In these cases water can enter the paint film and cause rotting to the putty or wood beneath. The rotting may be further aggravated by poor weather conditions. To prevent this from happening, windows should be painted regularly with an exterior wood paint.

In addition to repainting, areas that have corroded should be repaired with a resin-based repair product. This will ensure that the maximum amount of original fabric is retained. It is crucial to reduce the number of holes that are made into the frame to allow cable access, since they can let in moisture and cause decay.

The structural movement of the wall can cause deformations in the frame and sash. This can lead to the sash not fitting properly and jamming or sticking into the opening, and broken glass. This can be fixed frequently by fitting new frames for sash made of slow-growing deal (pine) or oak. The cill needs to be constructed from a sturdy hardwood, like oak, to prevent the movement of new and old work.

There are now several companies that manufacture Boston pattern wooden sash window repair Cambridge to fit most existing openings. They are available in various sizes and finishes that will fit the needs of modern homeowners. Together with quadruple draught strips and improved thermal insulation, these sashes can make a an enormous difference to the energy efficiency of a home.

Aesthetics

Many old wooden windows have an excellent aesthetic value as they often illustrate, in some way the materials and technologies and architectural taste of the time from which they date. They could also have a significant historical significance in their own right. This is particularly true of early windows that were not glazed in timber framed buildings where the great majority were merely a series of openings within the frame that were subdivided horizontally into mullions, and vertically into iron or wood bars to keep out intrusions.

It is essential to preserve the appearance of traditional wooden window joinery. It is essential that any decay that results from moisture penetration should be immediately stopped once it is recognised. It is recommended to do this by thorough painting, particularly if there is damage or deterioration. It is best to use paints designed to be used in a set (primer undercoat and finish) and adhere to the manufacturer's recommendations for preparation and number of coats at each stage.

Wet rot is a typical problem in older timber windows. The best method to stop it from becoming a problem is to take out any damaged or rotten sections as soon as possible to prevent the spread of the fungus that causes it. The replacement of wood that is rotting should be done with care and with a slow-growing deal (pine) and, if possible, the same species as which is being removed in order to prevent differential movement between the new section and existing timbers.

glass repair cambridge became more affordable and abundant during the late medieval period and into the 17th century. In the process, the openings for glazed windows on timber-framed houses were more elaborate, with moulded mullions, wooden tracery and deep projecting cills. In recent years, glazing was fixed to frames that were rebated with glazing sprigs rather than lead cames. This method of glazing is not just less prone to leaking but it also allows larger and clearer sheets of glass to be used in the windows than would otherwise be possible without the need for lead lights.

Energy efficiency

The traditional timber windows are energy efficient because of their thickness and multilayer construction, as well as their care for the smallest of details. The large glass areas, deep projecting cills and large glazing areas minimize air infiltration. The windows can be made to increase their energy efficiency with draught-proofing and secondary glazing. However it is essential to remember that such measures should be evaluated in relation to the overall quality and appearance of the original window.

As a result, retaining existing historic windows that require repair instead of replacing them makes sense especially when their thermal improvements can be achieved economically through simple repairs and improvements. The windows that are historic have a lot considered to be of historical value because they demonstrate a variety in technological advancement and changes in architectural taste. The pressures to replace these windows are usually based on the assumption that windows of the past will require replacement in the near future, however the majority of them are capable of serving for 150, 200 or even 250 years, if properly maintained.

It is essential to realize that decay issues associated with traditional timber windows can be preventable by timely and thorough repairs. In addition it is crucial to spot damp penetration issues and fix them promptly to avoid serious damage. Early paint deterioration could be a problem as it allows moisture to penetrate into the wood, leading to wet rot. It is not uncommon for this issue to go unnoticed until paintwork begins to crack or become wavier. However, it could cause structural damage and lead to further decay.

A high-quality paint will prevent this moisture from entering. To avoid condensation and mould it is essential to keep the paintwork as clean as you can. Modern synthetic paints are problematic because they are often water-resistant and may cause mildew to develop in the window frame.

The majority of older windows were constructed of sapwood-rich timber. These timbers are susceptible to deterioration quickly when exposed to wet weather, but can be protected with an extensive preservative treatment prior to when they are put to use. It is essential to select the right kind of wood for the location and climate, as these variables can affect the durability of the joinery. Local window manufacturers produce various types of timber sash that can be customized to fit specific openings from the past. They can be constructed according to the standard Boston pattern dimensions or to specific sizes that fit with the architectural style of historic buildings.

Maintenance

Regular inspections carefully redecorated, as well as prompt repairs can extend the life of timber windows. The primary cause of wood decay is moisture leaking through deteriorated paint or putty. This can be avoided by using a quality wood preservative and thoroughly painting the wood.

Repairs to old sash windows as well as frameless casement windows should be handled with care and with the least amount of disruption. Many traditional timber window replacement cambridge designs are repairable without removing the frame, and this method should be taken whenever feasible. Loose or peeling paint must be removed with care and sanded lightly to improve the key of the surface and facilitate an easier adhesion of the new coating. Be careful to avoid stripping paint layers that might have historical significance, and where these are present it is recommended that a paint analysis be carried out.

If a portion of wood is rotting, the best solution is to take it off and replace it with timber inserts that are shaped to match the existing profiles. The timber that is inserted should be treated using wood preservative, and the joint between masonry sub-cill and timber cill should be sealed.

Replacement of traditional windows with PVC-u can be an attractive option, especially when the installer offers an "all-in-one" installation that handles removal and replacement in one day. It is crucial that the person who installs replacement windows has a complete knowledge of the construction and history of traditional timber frames. This will allow them to make the appropriate recommendations for energy efficiency improvements as well as other technological improvements that don't affect the appearance of a building that is historic. The window installers who provide replacement windows must be registered with a Competent Persons Scheme such as FENSA. This will ensure that replacement windows are approved under Building Regulations as a suitable alternative. It is quite possible for an experienced and skilled carpenter to install PVC-U windows that fit the the original building. This is especially true when the windows are in listed buildings or conservation areas.
