Maintaining Timber Windows

A well-maintained wooden window is an important component of a historical building. It reflects in different levels, the materials and technologies of the time in which it was made, the craftsmanship and architectural taste.

If repairs are possible to existing windows are required, they should be made in situ. Repairing the worst areas of decay is possible with the help of specialized resin-based systems.

Durability

Timber windows were built to last for centuries. They require regular maintenance to keep them looking great. The most common maintenance tasks include sash-cord repairs as well as tightening sash pulleys and painting. The demand for upgrading timber windows to improve efficiency and energy efficiency is also increasing. This could include replacing old glazing units, repairing the upvc window lock repair rebates that are in place or installing new cills to improve air seal.

One of the main issues with traditional windows is damage caused by the corrosion of the paintwork. This is especially true when it comes to sash windows because the gaps between sashes may be quite large. In these situations, water can penetrate the paint film and cause rotting of the putty as well as the wood underneath. Weather conditions that are not ideal can accelerate the decay. To stop this from happening, windows need to be painted regularly with an exterior wood paint.

The areas that are damaged should be repaired using a resin-based product. This will ensure that the maximum amount of the original fabric is preserved. It is also important to reduce the number of holes you drill into the frame to allow cable entry since these could allow water in and cause decay.

The wall's structural movement can cause distortions in the frame as well as sash. This could result in sash no longer fitting correctly or sticking or jamming into the opening and cracked double glazing repairs cambridge. This can often be fixed by the fitting of new sash boxes made from slow grown deal (pine) or oak. The cill should be constructed of a durable hardwood, such as oak, to avoid the movement of new and older work.

To reduce the risk to reduce the risk of this happening, there are a number of companies who manufacture Boston pattern sash made of wood that can be fitted into most openings. These sash window repair cambridge are available in a variety of sizes and finishes that meet the needs of the modern homeowner. In conjunction with quadruple draught strip and improved thermal insulation, these new sash can make a substantial difference to the energy efficiency of a house.

Aesthetics

Many old timber frames have a high aesthetic appeal because they display, in a certain shape, the materials technology, the construction process, and the architectural aesthetics of the time they were made. They may also have significant historical value in their own right. This is particularly true for early unglazed windows in timber-framed buildings, where the majority of them were series of openings within structural frames subdivided horizontally by mullions, and vertically by iron or wood bars to protect against invaders.

Traditional window joinery made from timber can be a highly decorative element of a structure and is crucial to maintain its appearance. It is crucial that any decay caused by the penetration of moisture should be removed as soon as it is discovered. It is recommended to do this with thorough painting, especially where there is damage or degradation. It is recommended to choose paints that are intended 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.

The fungus responsible for wet rot can spread quickly in old windows made of wood. To prevent this from happening, take out any damaged or rotten parts as soon as you can. Replace rotting wood with slow-growing deal (pine) and, should it be possible, the same kind of timber as the one being removed, to avoid the possibility of differential movement.

Glass became less expensive and more abundant in the late medieval era and into the 17th century. This led to the openings for double glazed door repairs windows on timber-framed houses became more complex with moulded mullions, tracery made of wood and deep projecting cills. In recent times, glass was pinned into frames that were rebated using glazing sprigs, not lead cames. This method of glazing is not just less susceptible to leaks, but it can allow for much wider, clearer sheets of glass to be used in windows than would otherwise have been possible without the need for lead lights.

Energy efficiency

Traditional timber windows offer a good energy performance due to their thickness and multi-layer construction. They also pay attentive attention to detail. The large glass surfaces, the deep projecting cills and large glazing areas reduce air infiltration. With secondary glazing and draughtproofing, windows can be made more efficient to improve their energy efficiency. However it is crucial to remember that such measures should be evaluated in relation to the overall quality and Sash window repair cambridge appearance of the original window.

Therefore, keeping existing historic windows that require repair rather than replacing them is sensible particularly when thermal enhancements can be achieved inexpensively with simple repairs and improvements. Older windows are usually of historical significance, since they demonstrate a variety in technological advancement and changes in architectural taste. Most people think that these windows will need to be replaced in the near future. However, many of them are still in service for 150, 200, or even 250 years if they are maintained with proper maintenance.

It is crucial to recognize that the decay issues that are associated with traditional timber windows can be prevented through regular maintenance and prompt repairs. It is also important to identify damp problems and correct them swiftly to avoid major damage. Paint deterioration that occurs early can be a problem because it allows moisture to penetrate into the wood, causing wet rot. It is not uncommon for this damage to go unnoticed until the paintwork begins to crack or becomes wavy. However, it can cause structural damage and further decay.

A quality paint will prevent moisture penetration. To avoid condensation and mould it is crucial to keep the paintwork as clean as you can. Modern synthetic paints can be problematic because they are usually formulated to be water-resistant, which can lead to the formation of mildew inside the window frame.

The majority of older windows were constructed from timber with an extensive proportion of sapwood. These timbers deteriorate quickly if exposed to rain, but they can be protected with a thorough preservation treatment before use. It is essential to select the right type of wood for your location and the climate, since these factors can affect the longevity of the joinery. Local window manufacturers provide a wide range of sash timbers that can be made to fit the historic openings. They can be produced in the standard Boston pattern or in custom sizes to fit historical buildings.

Maintenance

The lifespan of windows made of timber can be extended significantly by regular inspection, careful redecoration and prompt upvc door repair. The most common reason for the decay is moisture intrusion through deteriorated putty and paint. This can be avoided by using a good wood preservative and thoroughly painting the wood.

It is important that repairs to old sash or casement windows are well executed and completed with minimal disruption. Many of the traditional designs for timber windows are repairable without removing the frame, and this method should be followed whenever possible. Paint that is peeling or loose should be removed carefully and lightly sanded to improve the 'key' of the surface, allowing for a better adhesion of the new coating. It is essential to not remove old paint layers, as they may have historical value.

When a section of wood has rotted the best way to deal with it is to remove it and replace it with timber inserts designed to match existing profiles. The inserted wood should also 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 is an attractive option, especially when the installer offers an "all-in-one" installation that takes care of removal and replacement in the span of a day. It is crucial that the person who installs replacement windows has a full understanding of the construction and history of traditional timber frames. This will allow them to make the appropriate recommendations for energy-efficiency improvements and other technological improvements that don't harm the character of a historic building. Window replacements should be registered with a Competent Persons Scheme such as FENSA. This will ensure the replacements are approved under Building Regulations as a suitable alternative. A skilled carpenter can put in PVC-u windows that conform to the original building's style. This is especially true where the windows are located in listed buildings or conservation areas.
