Maintaining Timber Windows

A well-maintained window made of timber is a significant part of the historic fabric of a structure. It demonstrates in various degrees the different materials and technologies design, craftsmanship and aesthetics of the time period that it was built in.

If possible, repairs should be done in-situ. Repairing the worst areas of decay can be done by using specialized resin-based systems.

Durability

Timber windows were built to last hundreds of years. But, they have to be maintained to keep them looking great and working properly. The most frequent maintenance tasks include sash-cord repairs as well as tightening sash pulleys and painting. The need to upgrade timber upvc windows cambridge in order to improve efficiency and energy efficiency is also increasing. This could include replacing old glazing units, repairing 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 particularly true when windows with sash are involved since the gaps between the sashes can be very wide. In these instances water can get into the paint film and cause decay of the putty and the wood underneath. The rotting may be further aggravated by weather conditions that are not ideal. To stop this from happening windows from becoming rotten, they must be regularly painted with an exterior wood paint that is suitable.

In addition to repainting, areas that have corroded must be repaired using the help of a resin-based repair solution. This will ensure that the highest possible amount of the original fabric remains. It is essential to limit the number of holes that are made into the frame in order to allow cable access, because they could let in moisture and cause decay.

Another significant problem with older windows is the structural movement within the wall, which could cause deformation of the frame and sash. This can result in the sash fitting incorrectly, jamming or sticking in the opening, and even broken glass. This can be corrected often by fitting new sash frames constructed of slow-grown deal (pine), or oak. The cill needs to be constructed of a strong hardwood like oak, to avoid shifting between the new and existing work.

There are several companies that manufacture Boston pattern wooden sash that fit most existing openings. These sash are available in a variety of sizes and finishes that meet the needs of the modern homeowner. 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 timber windows have a high aesthetic value since they usually demonstrate, in a way the materials and technologies and architectural taste of the period from which they date. They also may have a significant historical significance in their individual cases. This is especially true for early windows that were not glazed in timber-framed structures, where the great majority were just a collection of openings within the frame that were subdivided horizontally into mullions and iron or wood bars to keep out intrusions.

It is essential to preserve the appearance of traditional timber window seal replacement near me joinery. It is crucial that any decay caused by the penetration of moisture should be removed as soon as it is discovered. This can be done by applying a thorough coat of paint, particularly in areas where there has already been damage or degradation. It is best to choose paints that are intended to be used in a system (primer undercoat and finish) and adhere to the manufacturer's recommendations for preparation and number coats at each stage.

Wet rot is a frequent problem for old timber windows and the best way to stop it becoming a problem is to take out sections that are damaged or rotten as soon as possible to prevent the spread of the fungus responsible for it. Replace rotting wood with slow-grown deal (pine) and, if possible, the same kind of timber as the one that is being removed, to prevent any differential movement.

In the late period of the 17th century and the middle of the medieval period, glass became cheaper and more abundant, and the openings for glazed glass in timber-framed buildings gradually became more sophisticated, with tracery made of wood moulded mullions, moulded mullions, and deep projection cills. In recent years, glazing was fixed into frames that were rebated with glazing sprigs rather than lead cames. This method of double Glazing seal repairs is not just less prone to leaking but it also allows larger, clearer sheets of glass to be used in the windows than would otherwise be possible without the need for lead lights.

Energy efficiency

Traditional timber windows offer an excellent energy performance due to their thickness and multi-layer construction, as well as meticulous attention to detail. The large glass surfaces, the deep projection cills and wide glazing areas minimize air infiltration. The windows can be made to improve their energy efficiency through draughtproofing and secondary glazing. It is essential to remember that these measures must be taken into consideration when it comes to the overall integrity and appearance of the original windows.

So, retaining old windows that are in need of repair rather than replacing them makes sense particularly when thermal enhancements can be made inexpensively with simple repairs and improvements. The windows that are historic have a lot of historical value, as they demonstrate a variety in technical development and changes to architectural style. The pressures to replace these windows are typically based on the assumption that windows of the past will require replacement in the near future, however most are still in a position to last for 150, 200 and even 250 years, if properly maintained.

It is essential to understand that the decay problems associated with traditional timber windows can be avoided by regular maintenance and prompt repairs. Additionally, it is essential to identify damp penetration problems and to remedy them quickly to prevent serious damage. Early deterioration of paint is a major issue, as it allows moisture to penetrate the wood and cause wet rot. It is not uncommon for this damage to go unnoticed until the paintwork starts to crack or turn curly. However, it can cause structural damage and further decay.

A good paint will stop moisture from entering the paint. To avoid condensation and mould it is crucial to keep the paintwork as clean as it can be. Modern synthetic paints pose a problem because they are water-resistant and may cause mildew to grow in the window frame.

The majority of windows from the past were constructed from sapwood-rich wood. These timbers can deteriorate very quickly when exposed to wet weather, however they can be protected with a thorough treatment of preservative before they are put to use. It is also essential to ensure that the kind of timber used is well-suited to the location and climate conditions, since these factors will influence the durability of the joinery. Local window manufacturers create a range of sash made of timber that can be tailored to fit specific openings from the past. They can be built according to the standard Boston pattern dimensions, or to custom dimensions that are compatible with historic buildings.

Maintenance

The life of timber windows can be extended considerably through regular inspections, careful redecoration and prompt repair. The primary cause of wood decay is moisture leaking through the deteriorated paint and putty. This can be avoided by using a quality wood preservative and thoroughly painting the wood.

Repairs to sash windows that are old and window seal repairs frames made of casement must be done with care and with minimal disruption. It is possible to repair the majority of traditional wooden window repairs cambridge designs without having to remove the frame. This is a must whenever it is possible. Remove loose or peeling paint and lightly sand the area to improve the "key" of the surface. This will allow the new coating to adhere better. It is important to avoid stripping old paint layers which might have historical significance and if they are present, it is recommended that a paint analysis be conducted.

When a piece of wood is rotten, the best option is to take out the rotten material and replace it with spliced-in timber inserts that are shaped to match the existing profiles. The inserted timber should also be treated using wood preservative. The junction between masonry sub-cills and timber cill should be sealed.

It is tempting to replace traditional windows with PVC u, especially when the installer provides an 'all-in-one' installation which includes both replacement and removal in one day. It is, however, vital that the installer of replacement windows has a full understanding of the construction and history of traditional timber frames. This will enable them to make the appropriate suggestions for energy efficiency improvements and other technical improvements that do not alter the historic character of a building. Those who provide replacement windows should be registered with a Competent Persons Scheme such as FENSA. This will ensure the replacements are approved in accordance with Building Regulations as a suitable alternative. A skilled carpenter can put in PVC-u Windows that are sympathetic to the original building's style. This is especially true where windows are installed in listed buildings or conservation areas.
