Maintaining Timber Windows

A well-maintained wooden upvc window renovation is an essential element of a building that is historic. It reflects, in various degrees, the materials and technologies of the time period it was constructed, as well as the architectural style and craftsmanship.

If it is possible, repairs must 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 hundreds of years. They do require maintenance to keep them looking great. Maintenance tasks include upvc doors repairs to sash cords and retightening pulleys for sash and painting. The demand for upgrading timber windows to increase efficiency in energy use is also growing. This may mean replacing old glass units, fixing the window rebates that are in place, or installing new cills to allow for improved air sealing.

The corrosion of paintwork is a major problem with traditional windows. This is particularly important when windows with sash are involved since the gaps between sashes can be extremely wide. In these instances water may get through the paint film and cause rotting of the putty and the wood beneath. The weather can be a factor in accelerating the decay. To prevent this windows, they should be painted regularly using an exterior wood paint that is suitable.

Corroded areas should be repaired with resin-based products. This will ensure that the maximum amount of original fabric is preserved. It is also necessary to minimise the number of holes you drill into the frame for cable entry, as they could allow water in and cause decay.

The wall's structural movement can also lead to distortions in the frame as well as sash. This could result in the sash fitting incorrectly jamming, sticking or sagging in the opening, or breaking glass. This can be corrected often by fitting new sash frames made of slow-grown deal (pine), or oak. The cill should be constructed from durable hardwood such as oak to prevent movement between the existing and new work.

There are a variety of companies that produce Boston pattern wooden sash to fit into the majority of existing openings. The sash is available in a range of sizes and finishes to suit the requirements of the modern homeowner. Combined with quadruple draught strips and a better thermal insulation, these new sash can make a substantial difference to the energy efficiency of a home.

Aesthetics

A lot of old timber frames possess a dazzling aesthetic appeal, as they show, in some shape, the materials, technology, and architectural aesthetics of the time they were built. They also may have a significant historical significance in their own right. This is especially true of early unglazed windows in timber-framed buildings, where the majority were series openings in structural frames subdivided horizontally by mullions with vertical wood or iron bars to keep out invaders.

Traditional timber window joinery is a beautiful element of a structure and is crucial to maintain its appearance. It is crucial that any decay caused by moisture penetration should be stopped as soon as it is identified. It is recommended to do this by thorough painting, especially if there is damage or deterioration. It is recommended to use paints designed to be used in a set (primer undercoat and finish), and to adhere to the manufacturer's recommendations for preparation and number of coats at each stage.

Wet rot is a frequent issue in older timber windows. The best way to stop it becoming a problem is to take out any damaged or rotten parts as soon as possible to stop the spread of the fungus that causes it. Replace rotting wood with slow-growing deal (pine) and, if possible, the same type of timber as the one being removed to prevent the possibility of 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 sophisticated with wooden tracery as well as moulded mullions and protruding cills. In recent years, glazing was fixed to frames that were rebated using double glazing repairs cambridge sprigs rather than lead cames. This method of glazing is not only less prone to leaking but it can allow for more expansive clearer, more transparent sheets of glass to be used in the windows than would have been possible without the need for leaded lights.

Energy efficiency

Traditional timber windows offer an excellent energy performance due to their thickness and multi-layer construction, as well as careful attention to detailing. They also feature large glass areas and projecting cills that reduce air infiltration. The windows can be made to increase their energy efficiency by draught-proofing and secondary glazing. However it is essential to keep in mind that any such measures should be viewed in relation to the overall integrity and appearance of the original upvc window lock repair.

So, retaining existing historic windows that are in need of repair instead of replacing them is logical especially when their thermal enhancements can be achieved cost-effectively through simple repairs and upgrades. Older windows typically have an historic value that illustrates a variety of technological advances and changes in architectural taste. The pressures to replace these windows are typically based on the assumption that the old windows will need replacement in the near future, however most are still in a position to last for 150, 200 or even 250 years if they are properly maintained.

It is important to recognise that the decay problems that are typical of timber windows can be prevented through regular maintenance and prompt repairs. In addition it is vital to identify damp penetration problems and to remedy them quickly to avoid major damage. The early deterioration of paint is a major issue, since it allows moisture penetrate the wood and cause wet rot. This damage is often not apparent until the paintwork is wavy or cracked but it can cause severe structural damage and lead to further decay.

A good quality paint will stop this moisture penetration. It is also necessary to keep the paintwork spotless to avoid mould and condensation. Modern synthetic paints pose a problem because they are water-resistant, and can cause mildew to develop within the window seal replacement near me frame.

The majority of older windows were manufactured from timber containing an extensive proportion of sapwood. These timbers can deteriorate quickly when exposed to rain, however they can be protected by a thorough preservation process prior to use. It is also important to ensure that the type of wood used is suitable to the climate and site conditions, as these factors can affect the longevity of the joinery. Local plastic window repair manufacturers produce a range of sash made of timber that can be customized to fit specific historic openings. They can be constructed according to the standard Boston pattern dimensions or to custom sizes that are in keeping with historic buildings.

Maintenance

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

Repairs to old sash windows as well as frameless casement windows must be done with care and minimal disruption. A lot of traditional wooden window designs are repairable without removing the frame, and this option should be taken whenever possible. Peeling or loose paint should be removed with care and sanded lightly to improve the 'key' of the surface and facilitate an improved adhesion of the new coating. It is essential to avoid removing old paint layers, which could have historical significance.

When a piece of wood has become rotten the best way to proceed is to remove the rotted material and replace it with spliced-in inserts that are shaped to match existing profiles. The wood that is being inserted should be treated with a wood preserver and the connection between the timber cill and masonry sub-cill should be sealed.

It can be tempting to replace traditional windows with PVC u, especially if the installer offers an 'all-in-one' installation which includes removal and replacement within a single day. However, it is essential that the person installing windows replacement has a thorough knowledge of the construction and history of traditional wooden frames. This will allow them to make the appropriate recommendations for energy-efficiency improvements and other technological improvements that don't alter the appearance of a historic building. Anyone who installs replacement windows must be registered under a Competent Persons Scheme such as FENSA. This will ensure the replacements are deemed acceptable in accordance with Building Regulations as a suitable option. It is certainly possible for an experienced and skilled carpenter to install PVC-U windows that are sympathetic to the character of the building originally. This is especially true when windows are installed in listed buildings or conservation areas.
