Maintaining Timber Windows

A well-maintained wooden window is a crucial component of a historical building. It reflects, in various levels, the materials and techniques of the time period it was constructed, as well as the architectural style and craftsmanship.

Whenever possible repairs to existing windows are required, they should be made in-situ. Proprietary resin-based ventilation repair cambridgeshire systems can be used to fix the worst areas of decay without removing the entire window.

Durability

The windows made of timber in many old structures were designed to last for a long time. They do require maintenance to keep them looking great. Maintenance tasks include repairs to sash cords, retightening of pulleys on sash, and painting. The need to upgrade timber windows in order to improve efficiency and energy efficiency is also increasing. This can include replacing old glazing units, fixing the window doctor near me rebates that are in place or installing new cills to increase the air seal.

One of the main issues with traditional windows is damage caused by the corrosion of the paintwork. This is particularly important when windows made of sash are involved because the gaps between sashes can be quite wide. In these instances, water can penetrate the paint film and cause rotting of the putty and underlying wood. Weather conditions that are not ideal can accelerate the decay. To prevent this windows, they should be regularly painted with a suitable exterior wood paint.

In addition to repainting, corroded areas must be repaired using a resin-based repair product. This will ensure the maximum amount of the 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 let in water and cause decay.

The wall's structural movement could also cause distortions in the frame as well as the sash. This could result in sash no longer fitting correctly, sticking or jamming in the opening and cracked glazing. Often this can be corrected by fitting new sash boxes made from slow grown deal (pine) or oak. The cill should be made from a sturdy hardwood such as oak to avoid differential movement between the existing and new work.

To help reduce this problem, there are now a number of companies who manufacture Boston pattern sash made of wood that can be fitted into most openings. These sash are available in a variety of sizes and finishes that meet the needs of today's homeowner. Together with quadruple draught strips and a better thermal insulation, these new sash options can make significant improvements to the energy efficiency of a home.

Aesthetics

Many old timber frames have a great aesthetic appeal, as they reflect, in some form, the quality of the wood technology, design, and aesthetics of the time they were made. They also may have a significant historic value in their individual cases. This is particularly true of early windows that were not glazed in timber-framed buildings, in which the majority of them were series of openings within structural frames subdivided horizontally by mullions with vertical iron or wood bars to protect against intrusions.

Traditional timber window joinery can be a stunning element of a structure and is crucial to keep its appearance. It is crucial that any decay that results from the penetration of moisture should be stopped as soon as it is identified. It is best to do this by thorough painting, particularly if there has been damage or deterioration. It is recommended to use paints that are specifically designed to be used part of the system (primer undercoat, finish) and follow the manufacturer's instructions in terms of preparation and the number of coats needed at each stage.

Wet rot is a frequent problem in older timber windows. The best way to stop it growing is to eliminate any damaged or rotten sections immediately to prevent the spread of the fungus responsible for it. The replacement of rotting wood should be done with care and by using a slow-growing deal (pine) and, if possible, the same species as which is being removed in order to prevent any movement differences between the new section and existing timbers.

Glass became less expensive and more abundant in the late medieval period and into the 17th century. This led to the openings for glazed windows on timber-framed houses became more complex with moulded mullions, wooden tracery and cills that protruded deep. The glazing was increasingly placed within frames with rebates and secured with 'Cambridge Double glazing sprigs' rather than 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 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 focus on detail. They also have large glass areas as well as deep projecting cills that reduce air infiltration. With secondary glazing and draughtproofing, windows can be made more efficient to improve their energy efficiency. It is crucial to remember that these measures need to be considered in relation to the overall integrity and look of the original windows.

So, retaining old windows that require upvc door repair cost rather than replacing them is logical especially when their thermal enhancements can be made cost-effectively through simple repairs and improvements. Older windows typically have historical significance that demonstrates a range of technological advances and changes in architectural style. Many people believe that these windows will need to be replaced in the near future. However, many of them will last for 150, 200, or even 250 years if they are maintained with proper maintenance.

It is essential to realize that decay problems in traditional timber double glazed windows cambridge windows are easily prevented with prompt and thorough repairs. In addition it is crucial to recognize damp penetration issues and address them swiftly to avoid serious damage. Early paint deterioration is a major issue, 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 good quality paint will prevent this moisture from entering. It is also essential to keep the paintwork in good condition to avoid condensation and the growth of mould. Modern synthetic paints are problematic since they are usually water-resistant and may cause mildew to develop in the window frame.

The majority of older windows were made from timber that contained the majority of sapwood. These timbers can deteriorate quickly when exposed to rain, but they can be protected with an extensive preservation treatment prior to use. It is also important to ensure that the type of wood used is suitable to the climate and site conditions, since these factors can affect the longevity of the joinery. Local window manufacturers create various types of timber sash that can be tailored to fit specific openings in historic buildings. 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 span of windows made from timber can be extended significantly through regular inspections, careful redecoration and timely repair. The most common cause of decay is moisture intrusion through deteriorated putty and paint. This can be avoided by using a good wood preservative and thoroughly painting the wood.

Repairs to old sash windows and casement window frames should be done with care and minimal disruption. Many traditional timber window designs can be repaired without dismantling the frame, and this option should be used whenever it is possible. Remove loose or peeling paint and lightly sand the area to improve the "key" of the surface. This will enable the new coating to stick better. It is essential to not remove old paint layers that may have historical value.

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

Replacement of traditional windows with PVC-u can be an attractive option, especially when the installer provides an "all-in-one" installation service that can handle both removal and replacement within the span of a day. It is crucial that installers of replacement windows have a thorough understanding of the history and design of traditional timber frames. This will allow them to make appropriate recommendations for energy efficiency improvements as well as other technological improvements that don't harm the character of a building that is historic. Those providing replacement windows should be registered with a Competent Persons Scheme such as FENSA. This will ensure that replacement windows are deemed to be approved by the Building Regulations as a suitable option. It is certainly possible for an experienced and skilled carpenter to install PVC-U windows that match the character of the building originally. This is especially true where windows are installed in listed buildings and conservation areas.
