Maintaining Timber Windows

A well-maintained wooden Window Replacement cambridge is an important component of a historical building. It reflects in different degree the technology and materials of the time in which it was constructed, the craftsmanship and architectural taste.

If it is possible, repairs must be made in-situ. Repair systems made of resin can be used to repair the most damaged areas of decay without having to remove the entire window.

Durability

The windows made of timber in many old buildings were built to last for hundreds of years. But, they have to be maintained to keep them looking great and working properly. Maintenance tasks include repairs to sash cords, retightening of pulleys on sash, and painting. The need to upgrade timber windows to improve efficiency in energy use is also growing. This could mean replacing old glass units, fixing the window rebates that are in place, or installing new cills to allow for better air sealing.

A key problem with traditional windows is damage caused by the corrosion of the paintwork. This is particularly important when windows with sash are involved since the gaps between the sashes can be extremely wide. In these situations, water can penetrate paint film and cause rotting to the putty or wood beneath. The rotting process can be made worse by poor weather conditions. To stop this from happening, windows should be regularly painted with an exterior wood paint.

In addition to repainting, corroded areas need to be repaired with a resin-based repair product. This will ensure the maximum amount of the original fabric is preserved. It is essential to limit the number of holes made into the frame in order to allow cable entry, since they can let in moisture and cause decay.

The wall's structural movement can also lead to distortions in the frame and the sash. This could result in sash no longer fitting correctly and jamming or sticking to the opening and cracked glazing. Most often, this is corrected through the installation of new sash boxes made from slow grown deal (pine) or oak. The cill should be constructed of a durable hardwood, like oak, to avoid shifting between the new and older work.

To reduce the risk, there are now a number of companies who manufacture Boston pattern sash made of wood that can be fitted into most openings. They are available in various sizes and finishes to meet the requirements of modern homeowners. In conjunction with quadruple draught strip and a better thermal insulation, these sashes can make a significant improvements to the energy efficiency of your home.

Aesthetics

A lot of old timber frames have a great aesthetic appeal, as they reflect, in some shape, the materials technology, the construction process, and the architectural style of the time they were made. They also may have significant historical value in their in their own right. This is especially true of windows that were unglazed in the early days of timber-framed structures, where the majority were series of openings within frames of structural construction, which were divided horizontally by mullions with vertical iron or wood bars in order to keep out intrusions.

Traditional window joinery made of timber can be a highly decorative aspect of a building, and is essential to maintain its appearance. It is vital that any decay that results from moisture penetration should be immediately stopped once it is recognised. This is best done by a thorough painting process, especially in areas that have already suffered damage or degradation. It is recommended to use paints that are designed to be used in a set (primer undercoat and finish) and follow the manufacturer’s recommendations for preparation and number of coats at each stage.

Wet rot is a frequent problem in old timber windows. The best way to stop it becoming a problem is to take out sections that are damaged or rotten as soon as you can to stop the spread of the fungus that causes it. Replace the wood that is rotting with slow-growing deal (pine), and if possible, the same kind of timber that is being removed, to avoid the possibility of differential movement.

Glass became more affordable and abundant during the late medieval period and into the 17th century. In the process, cheap double glazed windows cambridge openings on timber-framed houses became more complex with moulded mullions, wooden tracery and deep projecting cills. In recent times, glass was fixed into frames that were rebated with glazing sprigs rather than lead cames. This method of glazing cambridge not only makes the windows less likely to leak and break, but also allows more clear glass sheets to be employed than would be possible without the use of led lights.

Energy efficiency

The traditional timber windows are energy efficient because of their thickness, multilayer construction and care for detail. The large glass areas, deep projecting cills and large glazing areas reduce air infiltration. Windows can be designed to increase their energy efficiency through draughtproofing and secondary glazing. It is crucial to keep in mind that these measures need to be considered in relation to the overall integrity and look of the original windows.

So, retaining old windows that are in need of repair instead of replacing them is sensible especially when their thermal enhancements can be achieved cost-effectively through simple upvc door repairs cambridge and upgrades. Older windows are usually considered to be of historical value because they demonstrate a variety in technical development and changes to architectural taste. Most people think that these windows will have to be replaced in the near future. However, many of them are still in service for 150, 200 or even 250 years if you take care of maintenance.

It is important to recognise that the decay issues caused by traditional timber windows can be avoided by thorough maintenance and swift repairs. It is also essential to spot damp issues and address them promptly to avoid major damage. The early deterioration of paint can be a problem because it allows moisture to penetrate into the wood, leading to wet rot. It is not uncommon for this damage to go unnoticed until paintwork starts to crack or turn curly. However, it could cause structural damage and further decay.

A good quality paint will prevent this moisture penetration. It is also essential to keep the paintwork in good condition to avoid mould and condensation. Modern synthetic paints pose a challenge since they are usually water-resistant and can cause mildew to grow in the window frame.

The majority of windows from the past were constructed from sapwood-rich wood. The timbers will deteriorate rapidly if exposed to rain, however they can be protected with an extensive preservation treatment prior to use. It is crucial to select the right type of wood for window replacement cambridge the site and the climate, since these factors will affect the durability of the joinery. Local window manufacturers offer a wide range of sash made from timber that can be made to fit the historic openings. They can be made in the standard Boston pattern or in custom sizes that can be adapted to historic buildings.

Maintenance

The life span of windows made from timber can be extended considerably through regular inspections carefully redecoration, and timely repair. The major cause of decay is moisture leaking through the deteriorated paint and putty. This can be avoided by using a good wood preservative and thoroughly painting the wood.

It is crucial that door repairs cambridge to the old sash and casement windows are done correctly and done with the minimum disturbance. A lot of traditional wooden window designs are repairable without removing the frame, and this method should be followed whenever feasible. Remove loose or peeling paint and lightly sand the area to improve the "key" of the surface. This will enable the new coating to adhere better. It is crucial to avoid removing old paint layers that may have historical value.

If a piece of wood is rotting the best option is to remove it and replace it with timber inserts shaped to match existing profiles. The inserted timber should also be treated with a wood preservative, and the joint between the masonry sub-cill and the timber cill should be sealed.

It's tempting to replace traditional windows with PVC U, particularly when the installer provides an installation that includes both replacement and removal within a single day. It is crucial that installers of replacement windows have a deep understanding of the history and construction of traditional timber frames. This will enable them to make the appropriate recommendations for energy efficiency improvements as well as other technological improvements that don't affect the appearance of an historic building. The windows that are replaced should be registered with a Competent Persons Scheme such as FENSA. This will ensure that the replacement windows are approved as a suitable option under Building Regulations. It is certainly possible for a skilled and experienced carpenter to install PVC-u windows that are sympathetic to the character of the building originally. This is particularly applicable when windows are situated within listed buildings or conservation areas.
