The Reasons Cambridge Window Is The Main Focus Of Everyone's Attention In 2023
Maintaining Timber Windows
A well-maintained timber window is an important element of the historic fabric of a structure. It illustrates in varying degrees the different materials and technologies design, craftsmanship and aesthetics of the period from which it dates.
When possible, repairs should be done in-situ. Repairing the most deteriorated areas of decay can be accomplished 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. But, they have to be maintained to keep them looking great and working correctly. Maintenance tasks include sash cord repairs and retightening sash pulleys and painting. There is also a rising demand to upgrade the timber windows to increase energy efficiency. This can include replacing old glazing units, repairing the window rebates that are in place or installing new cills for improved air seal.
The corrosion of paintwork is a major issue with traditional windows. This is particularly important when sash windows are concerned, as the gaps between sashes may be quite large. In these circumstances, water can penetrate the paint film and cause rotting of the putty as well as the wood beneath. Poor weather conditions can exacerbate the rotting. To prevent this, windows should be painted regularly with a suitable exterior wood paint.
Corroded areas should be repaired using a resin-based product. This will ensure that the best possible amount of the original fabric is preserved. It is also necessary to reduce the number of holes you drill into the frame for cable entry since these could allow water in and cause decay.
Another significant problem with older windows is structural movement in the wall that could cause deformation of the frame and the sash. This could result in sash no longer fitting correctly or sticking or jamming into the opening and cracked glazing. Often timber double glazed windows cambridge can be corrected by fitting new sash boxes that have been made from slow grown deal (pine) or oak. The cill should be constructed from durable hardwood such as oak to avoid any movement between the old and new work.
To alleviate this issue There are a variety of companies that make Boston pattern sash made of wood that can be fitted into most openings. They are available in a variety of sizes and finishes that meet the requirements 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 frames have a high aesthetic appeal, since they reflect, in some form, the quality of the wood, technology, and architectural aesthetics of the time they were constructed. They also may have a significant historical significance in their own right. This is particularly true for early unglazed windows in timber-framed buildings, in which the majority of them were series of openings in structural frames subdivided horizontally by mullions with vertical iron or wood bars in order to protect against intrusions.
Traditional window joinery made of timber can be a highly decorative feature of a building and it is important to keep it looking good. As soon as you notice any signs of decay caused by moisture penetration it is crucial to stop it. It is best to do this through thorough painting, particularly if there has been damage or degradation. It is advisable to use paints specifically designed to be used part of the system (primer, undercoat and finish) and follow the manufacturer's guidelines regarding preparation and number of coats needed at each stage.
Wet rot is a typical issue in older timber windows. The best method to stop it from developing is to remove sections that are damaged or rotten as soon as possible to prevent the spread of the fungus responsible for it. The replacement of rotting wood should be carefully undertaken with a slow-growing deal (pine) and, whenever possible, the same species as which is being removed to avoid shifting between the new section and existing timbers.
Glass became less expensive and more abundant in the late medieval period and into the 17th century. In the process, the openings for glazed windows on timber-framed houses became more complex with moulded mullions and traceries, made of wood and deep projecting cills. In recent times, glass was fixed to frames that were rebated with glazing sprigs instead of lead cames. This method of glazing not only makes windows less likely to leak and break, but also allows larger sheets of glass to be employed than would be possible otherwise without the use of lead lights.
Energy efficiency
Traditional timber windows are energy efficient because of their thickness and multilayer construction, as well as their care for detail. The large glass areas, deep projecting cills and large glazing areas minimize air infiltration. With secondary glazing and draught proofing, windows can be upgraded to improve their energy efficiency. However, it is important to keep in mind that any such measures should be viewed in the context of the overall appearance and integrity of the original window.
Therefore, keeping existing historic windows that are in need of repair instead of replacing them makes sense especially when their thermal enhancements can be achieved economically through simple repairs and upgrades. Older windows typically have an historic value that illustrates a variety of technical development and changes in architectural style. Most people think that these windows will have 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 essential to realize that decay problems with traditional timber windows can be preventable by timely and thorough repairs. It is also essential to identify damp problems and address them promptly to avoid major damage. Early paint deterioration is a major problem because it allows moisture to penetrate the wood and cause wet rot. The damage is usually not evident until the paintwork is cracking or wavy however, it can cause serious structural damage, and could lead to further decay.
A high-quality paint will stop this moisture from entering. To prevent mould and condensation it is crucial to keep the paintwork as clean as possible. Modern synthetic paints pose a problem because they are water-resistant and may cause mildew growth in the window frame.
The majority of windows from the past were constructed of sapwood-rich timber. These timbers are susceptible to deterioration rapidly if exposed to wet weather, however they can be protected with an extensive preservative treatment prior to when they are used. It is also essential to ensure that the type of wood used is suited to the climate and site conditions, as these factors affect the durability of the joinery. Local window manufacturers make various types of timber sash that can be customized to fit specific openings from the past. They are available in the standard Boston pattern or in custom sizes to fit historical structures.
Maintenance
The life span of windows made from timber can be extended by regular inspection, careful 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 quality wood preservative and thoroughly painting the wood.
Repairs to sash windows that are old and casement window frames should be handled with care and minimal disruption. Many of the traditional designs for timber windows can be repaired without removing the frame, and this approach should be taken whenever possible. Remove any peeling or loose paint and lightly sand the area to improve the 'key" of the surface. This will allow the new coating to adhere better. Care should be taken to avoid stripping paint layers that could have historical value If these are present, it is recommended that a paint analysis be carried out.
Where a section of timber is rotten, the best course of action is to take out the rotten material and replace it with spliced-in timber inserts that are shaped to match existing profiles. The inserted wood should also be treated with wood preservative and the joint between the timber cill and the sub-cill for masonry should be sealed.
Replacement of windows made of traditional PVC-u may be an attractive option, especially when the installer offers a 'one stop shop' installation that handles both removal and replacement within a day. It is essential that installers of replacement windows have a thorough understanding of the history and construction of traditional timber frames. This will enable them to make the appropriate suggestions for improvements to energy efficiency and other technical improvements that won't harm the historic character of a building. Window replacements should be registered with a Competent Persons Scheme like FENSA. This will ensure that the replacements are approved as a suitable option under Building Regulations. It is certainly possible for an experienced and skilled carpenter to install PVC-u windows that are sympathetic to the character of the original building. This is particularly true where the windows are located in listed buildings and conservation areas.
