The Reason Cambridge Window Is Fast Increasing To Be The Hottest Trend For 2023
Maintaining Timber Windows

A well-maintained wooden window is a crucial component of a historical building. It illustrates in varying degrees the materials and technologies, craftsmanship and architectural taste of the time period from which it dates.

When repairs are feasible to windows that are already in use should be done in-situ. Repairing the most severe areas of decay is possible with the help of specialized resin-based systems.

Durability

The windows made of wood in many old buildings were built to last for hundreds of years. However, they need to be maintained to ensure they look good and functioning correctly. The most frequently-asked maintenance tasks are repairs to sash-cords and re-tightening the sash pulleys and painting. There is also a rising demand for upgrading timber windows to improve energy efficiency. This could mean replacing old glass units, fixing the window rebates that are in place, or installing new cills that allow for improved air sealing.

A key problem with traditional windows is the damage caused by the corrosion of the paintwork. This is particularly important in the case of sash windows as the gaps between sashes can be extremely large. In these circumstances water can get into the paint film and cause rotting of the putty as well as the wood beneath. The rotting can be exacerbated by weather conditions that are not ideal. To stop this from happening windows from becoming rotten, they must be painted regularly with a suitable exterior wood paint.

Corroded areas should also be repaired using resin-based products. This will ensure that the greatest amount of original fabric is preserved. It is also important to reduce the number of holes that are drilled into the frame for cable entry as these can admit water and lead to decay.

The structural movement of the wall could also cause distortions in the frame and the sash. This could result in the sash not fitting properly, jamming or sticking in the opening, and even broken glass. This can be corrected often by putting in new frames for sash made of slow-growing deal (pine), or oak. The cill must be constructed from durable hardwood such as oak to avoid differential movement between the old and new work.

There are a variety of companies that produce Boston pattern wooden sash to fit into the majority of existing openings. They are available in various sizes and finishes to suit the needs of modern-day homeowners. In conjunction with quadruple draught strip and improved thermal insulation, these sashes can make a an enormous difference to the energy efficiency of a home.

Aesthetics

Many old timber frames possess a dazzling aesthetic appeal, as they display, in a certain form, the materials technology, design, and style of the time they were made. They also may have a significant historic value in their in their own right. This is particularly true of windows that were unglazed in the early days of timber-framed buildings, where the majority were series of openings within structural frames that were subdivided horizontally by mullions and vertical iron or wood bars to protect against invaders.

It is crucial to maintain the appearance of traditional timber window joinery. It is vital that any decay that results from water penetration is stopped as soon as it is recognised. It is best to do this by thorough painting, especially where there has been damage or deterioration. It is best to use paints that are designed to be used in a system (primer undercoat and finish) and to follow the manufacturer's guidelines for preparation and number coats at each stage.

Wet rot is a typical problem for old timber windows. The best way to stop it growing is to eliminate sections that are damaged or rotten immediately to stop the spread of the fungus responsible for it. Replace the wood that is rotting with slow-growing deal (pine) and, should it be possible, the same type of wood as the one 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 sophisticated with wooden tracery, moulded mullions and deep projecting cills. In recent times, glass was fixed to rebated frames with glazing sprigs, not lead cames. This method of glazing not only makes windows less likely to leak, but also allows for more clear glass sheets to be used than would have been possible without the use of led lights.

Energy efficiency

Traditional timber windows provide excellent energy efficiency due to their thickness and multi-layer construction, as well as attentive attention to detail. They also have large glass areas and projection cills which reduce air infiltration. The windows can be modified to increase their energy efficiency through draughtproofing and secondary glazing. double glazing company cambridge is essential to keep in mind that these measures must be considered when it comes to the overall appearance and integrity of the original windows.

It is logical to repair or upgrade existing windows that are older rather than replacing them, especially when the improvement in thermal efficiency can be achieved through simple repairs. Older windows typically have an historic value that illustrates a variety of technological advances and changes in architectural taste. Most people think that these windows will need to be replaced in the near future. However, they can still provide service for 150,200, and even 250 years if they are maintained with proper maintenance.

It is crucial to recognize that the decay problems that are typical of timber windows can be avoided through regular maintenance and prompt repairs. It is also important to spot damp issues and fix them quickly to avoid major damage. Early paint deterioration is a concern because it allows moisture to get into the wood, leading to wet rot. The damage is usually not noticed until the paintwork becomes wavy or cracked, but can cause significant structural damage and lead to further decay.

A quality paint will prevent moisture penetration. To prevent mould and condensation, it is important to keep the paintwork as clean as possible. Modern synthetic paints pose a problem because they are water-resistant and can cause mildew growth within the window frame.

The majority of windows from the past were made from timber that contained an extensive proportion of sapwood. These timbers can deteriorate very rapidly if exposed to wet weather, however they can be protected with a thorough treatment of preservative before they are used. It is also essential to ensure that the type of wood used is suited to the site and climate conditions, since these factors affect the durability of the joinery. Local window manufacturers produce various types of timber sash that can be adapted to fit specific historic openings. They can be made in the standard Boston pattern or in custom sizes that can be adapted to the architectural style of historic buildings.

Maintenance

The lifespan of windows made of timber can be extended significantly through regular inspections carefully redecoration, and timely repair. The most common reason for the decay is moisture infiltration through deteriorated paint and putty. This can be prevented by using a quality wood preservative and thoroughly painting the wood.

It is crucial that repairs to the old sash and casement windows are well executed and completed with the minimum disturbance. It is possible to fix the majority of traditional wooden window designs without taking the frame off. This should be done whenever possible. Remove any peeling or loose paint and then lightly sand the surface to improve the "key" of the surface. This will allow the new coating to stick better. It is crucial to not remove old paint layers, which may have historical value.


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

It can be tempting to replace traditional windows with PVC U, particularly when the installer offers an 'all-in-one' installation which includes removal and replacement in one day. However, it is essential that the person installing windows replacement has a thorough understanding of the construction and history of traditional wooden frames. This will allow them to make the right suggestions for improvements to energy efficiency and other technical improvements that do not alter the historical character of a building. Anyone who installs replacement windows should be registered with a Competent Persons Scheme such as FENSA. This will ensure that the replacements are deemed as a suitable solution in accordance with Building Regulations. It is quite possible for a skilled and experienced carpenter to install PVC-U windows that are sympathetic to the style of the original building. This is especially applicable when windows are situated within conservation areas or listed buildings.
