Maintaining Timber Windows

A well-maintained plastic window repair made of timber is an important element of the historical structure of a building. It reflects in varying degree the materials and techniques of the time in which it was constructed, the craftsmanship and architectural taste.

If it is possible, upvc door repair cost repairs, toptohigh.com, must be made in-situ. Repairing the most severe areas of decay is possible with the help of specialized resin-based systems.

Durability

Timber windows were built to last for hundreds of years. They do require maintenance to keep them looking great. The most frequently-asked maintenance tasks include repairs to sash cords as well as tightening sash pulleys and painting. There is also a growing demand to upgrade timber windows to improve energy efficiency. This could include replacing old glazing units, repairing the window rebates that are in place or installing new cills to improve air seal.

The deterioration of paintwork is a major problem with traditional windows. This is especially important when it comes to sash windows because the gaps between sashes can often be very large. In these situations water can get into paint film and cause rotting to the wood or putty underneath. The rotting process can be made worse by poor weather conditions. To prevent this from happening, windows need to be regularly painted with an exterior wood paint.

Areas that have been damaged must be repaired with a resin-based product. This will ensure that the greatest amount of the original fabric is preserved. It is essential to limit the number of holes that are created into the frame in order to allow cable entry because they could let in moisture and cause decay.

The structural movement of the wall can also lead to deformations in the frame and the sash. This can result in sash not fitting correctly jamming, sticking or sagging in the opening, and even broken glass. This can be corrected often by fitting new sash frames made of slow-growing deal (pine) or oak. The cill needs to be constructed of a durable hardwood, such as oak, to prevent differential movement between new and existing work.

To reduce the risk There are several companies that manufacture Boston pattern sash made of wood that can be fitted into most openings. These sash come in a variety of sizes and finishes to suit the needs of modern homeowners. In conjunction with quadruple draught strip and better thermal insulation these sashes can make a significant improvements to the energy efficiency of your home.

Aesthetics

Many old timber windows have a great aesthetic value because they typically demonstrate, in a way the materials and techniques and architectural taste of the period from when they were built. They also may have a significant historical significance in their own right. This is especially true for windows that were unglazed in the early days of timber-framed structures, where the great majority were just a collection of openings within the frame, which were divided horizontally into mullions and wood or iron bars to deter invaders.

It is essential to preserve the appearance of traditional timber window joinery. As soon as you notice any signs of decay due to moisture penetration it is essential to stop it. This can be done by applying a thorough coat of paint, particularly in areas in which there is already damage or deterioration. It is recommended to use paints that are specifically designed to be used as part of the system (primer as well as undercoat, finish and primer) and to follow the manufacturer's recommendations regarding preparation and the number of coats needed at each stage.

The fungus that causes wet rot can quickly spread in old timber windows. To stop this from happening, remove any damaged or rotten parts as promptly as you are able to. Replace rotting wood with slow-growing deal (pine) and, should it be possible, the same type of timber that is being removed, to prevent differential movement.

In the late period of the 17th century and the middle of the medieval period, glass became less expensive and more abundant, so that the glazed openings in timber-framed buildings gradually became more sophisticated with wooden tracery, moulded mullions and deep projecting cills. Increasingly, the glazing was placed within frames with rebates and secured with 'glazing sprigs' rather than being inserted into lead cames. This method of glazing not only makes the windows less likely to leak, but also allows for more clear glass sheets to be utilized than would have been possible without the use of leaded lights.

Energy efficiency

Traditional timber windows have an excellent energy performance due to their thickness and multi-layer construction, as well as meticulous attention to detail. The large glass areas, the deep projection cills and wide glazing areas minimize air infiltration. The windows can be modified to increase their energy efficiency with draught-proofing and secondary glazing. It is essential to keep in mind that these measures need to be considered when it comes to the overall integrity and look of the original windows.

It is sensible to fix or upgrade historic windows rather than replace them, particularly when improvements in thermal efficiency can be made through simple repairs. The windows that are historic have a lot of historical significance, since they demonstrate a variety in technological advancements and changes to architectural style. Most people think that the windows will need to be replaced in the near future. However, they will last for 150, 200 or even 250 years if they are maintained with proper maintenance.

It is essential to realize that decay issues associated with traditional timber windows are easily prevented with timely and thorough repairs. In addition, it is essential to recognize damp penetration issues and fix them promptly to avoid major damage. The 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 apparent until the paintwork is wavy or cracked, but can cause significant structural damage and can lead to further decay.

A high-quality paint will stop this moisture from entering. To avoid condensation and mould, it is important to keep the paintwork as clean as possible. Modern synthetic paints pose a problem because they are often water-resistant, and can cause mildew to grow in the window frame.

The majority of older windows were constructed from timber with an extensive proportion of sapwood. These timbers are susceptible to deterioration quickly when exposed to wet weather, but can be protected by an extensive preservative treatment prior to when they are used. It is crucial to select the appropriate type of wood for your location and climate, as these factors can affect the longevity of the joinery. Local window manufacturers produce a range of sash made of timber that can be adapted to fit specific historic openings. They can be made in the standard Boston pattern or in custom sizes to fit historic buildings.

Maintenance

Regular inspections as well as careful redecoration and timely repairs can prolong the lifespan of windows made of timber. The primary cause of wood decay is the penetration of moisture through deteriorated paint or putty. This can be avoided by using a good wood preservative and painting the wood thoroughly.

It is important that repairs to old sash and casement windows are properly executed and completed with minimal disruption. Repairs can be made to the majority of traditional wooden window designs without having to remove the frame. This should be done as often as is feasible. Loose or peeling paint should be removed carefully and lightly sanded to improve the "key" of the surface and allow for an improved adhesion of the new coating. It is important to avoid stripping paint layers that may have historic value, and where these are present it is recommended that a paint analysis be conducted.

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

Replacement of windows made of traditional PVC-u can be an appealing option, particularly when the installer offers a "one-stop shop" installation that takes care of removal and replacement in one day. It is important that the installers of replacement windows are aware of the history and design of traditional timber frames. This will enable them to make the right suggestions for improvements to energy efficiency and other technical improvements that will not harm the character of a historic building. Those who provide cambridge replacement windows windows should be registered under a Competent Persons Scheme such as FENSA. This will ensure that the replacements are approved in accordance with Building Regulations as a suitable option. It is, of course, possible for an experienced and skilled carpenter to install PVC-U windows that are sympathetic to the style of the building originally. This is especially true where windows are situated in listed buildings and conservation areas.
