Maintaining Timber Windows

A well-maintained timber window is a significant element of the historic fabric of a structure. It illustrates in varying degrees the materials and technologies as well as the craftsmanship and architectural style of the time from which it originates.

If repairs are possible to existing windows are required, they should be made in-situ. Proprietary resin-based repair systems can be used to fix the most deteriorated areas without removing the entire window.

Durability

The timber windows in many old buildings were made to last for centuries. They do require some maintenance to keep them looking good. Maintenance tasks include repairs to sash cables as well as tightening the pulleys on sash, and painting. There is also a rising demand to upgrade timber windows to increase the efficiency of energy. This may mean replacing old glazing units, repairing existing window repair cambridge rebates or putting in new cills that allow for better air sealing.

One of the major issues with traditional windows is damage caused by the corrosion of the paintwork. This is particularly important when sash windows are involved as the gaps between sashes can be extremely wide. In these situations water can get into paint film and cause rotting to the wood or putty beneath. The rotting process can be made worse by weather conditions that are not ideal. To prevent this, windows should be regularly painted with an exterior wood paint that is suitable.

Corroded areas should also be repaired using resin-based products. This will ensure that the greatest amount of the original fabric is preserved. It is crucial to reduce the number of holes made into the frame to allow cable access, since they can let in moisture and cause decay.

Another major issue with older windows is structural movement in the wall that can cause deformation of the frame and the sash. This can result in sash no longer fitting correctly and jamming or sticking to the opening, and damaged glazing. This can often be fixed by the fitting of new sash boxes constructed from slow-growing deal (pine) or oak. The cill needs to be constructed of a strong hardwood such as oak, to avoid differential movement between new and old work.

To reduce the risk to reduce the risk of this happening, there are a variety of companies that produce Boston pattern wooden windows and doors cambridge (Recommended Internet site) sash that will fit into the majority of existing openings. They are available in a variety of sizes and finishes that meet the needs of today's homeowner. The new sash, combined with quadruple draft strip and a better thermal insulation, can make a significant difference to the energy-efficiency of a home.

Aesthetics

A lot of old timber frames have a high aesthetic appeal, as they display, in a certain shape, the materials technology, the construction process, and the architectural taste from the time period they were constructed. They may also have significant historical value in their own right. This is especially true of early windows that were not glazed in timber-framed structures, which were just a collection of openings within the frame that were subdivided horizontally into mullions and vertical iron or wood bars to keep out intruders.

Traditional timber window joinery is a beautiful feature of a building and it is important to keep it looking good. It is vital that any decay caused by moisture penetration should be immediately stopped once it is discovered. It is best to do this through thorough painting, particularly if there is damage or deterioration. It is advisable to use paints that are specifically designed to be used as part of a system (primer as well as undercoat, finish and primer) and follow the manufacturer's guidelines in relation to preparation and the amount of coats required at each stage.

Wet rot is a common problem for older timber windows. The best method to stop it from growing is to eliminate any damaged or rotten parts as soon as possible to stop the spread of the fungus that causes it. Replace the wood that is rotting with slow-growing deal (pine), and when possible, the exact type of timber that is 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 more affordable and plentiful so that glazed openings in timber-framed buildings gradually became elegant with wooden tracery, moulded mullions and deep protruding cills. In the past, more often, the glass was set within rebated frames and secured by 'glazing sprigs' rather than being inserted into lead cames. This method of glazing is not only less prone to leaks but also allows for more expansive and clearer sheets of glass to be used in windows than would be possible without the need for lead lights.

Energy efficiency

Traditional timber windows are energy efficient due to their thickness and multilayer construction as well as focus on particulars. They also feature large glass areas and deep projection cills which reduce air infiltration. With secondary glazing and draughtproofing the windows can be improved to increase their energy efficiency. However, it is important to keep in mind that these measures should be viewed in relation to the overall appearance and integrity of the window in its original form.

So, retaining old windows that require repair instead of replacing them is sensible, particularly when their thermal improvements can be achieved inexpensively with simple repairs and upgrades. Older windows are usually considered to be of historical value because they reflect a variety of technological advancement and changes in the architectural style. Most people think that these windows will have to be replaced in the near future. However, most can still provide service for 150, 200, or even 250 years if they are maintained with proper maintenance.

It is important to recognize that decay issues associated in traditional timber windows are avoidable with timely and thorough repairs. It is also essential to identify damp problems and address them promptly so that you can avoid serious damage. Early deterioration of paint is a major issue, as it allows moisture to penetrate the wood and cause wet rot. It is not uncommon for this damage to go unnoticed until the paintwork starts to crack or turn wavier. However, it can cause structural damage and lead to further decay.

A paint of good quality will block moisture penetration. To avoid condensation and mould it is crucial to keep the paintwork as clean as you can. Modern synthetic paints are problematic because they are water-resistant and can cause mildew to grow in the window repairs near me frame.

The majority of windows from the past were manufactured from timber containing an extensive proportion of sapwood. These timbers are susceptible to deterioration rapidly if exposed to wet weather, but can be protected by a thorough treatment of preservative before they are used. It is important to choose the right type of wood for the site and climate, as these factors can affect the longevity of the joinery. Local window repairs cambridge manufacturers have a wide range of sash made from timber that can be adapted to fit historical openings. They can be made to the standard Boston pattern dimensions, or to custom dimensions that are compatible with historic buildings.

Maintenance

The lifespan of windows made of timber can be extended significantly through regular inspections, careful redecoration and timely repair. The most common reason for decay is moisture infiltration through deteriorated putty and paint. This can be avoided with thorough painting and the use of an excellent wood preservative.

Repairs to old sash windows as well as casement window frames should be done with care and with the least amount of disruption. Many traditional timber window designs can be repaired without dismantling the frame, and this method should be used whenever it is feasible. Remove any peeling or loose paint and lightly sand the area to improve the "key" of the surface. This will enable the new coating to stick better. Be careful to avoid stripping paint layers that could have historical value and if they are present, it is recommended that a paint analysis be carried out.

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

Replacement of windows made of traditional PVC-u can be an appealing option, particularly when the installer provides a "one-stop shop" installation that handles removal and replacement in one day. It is, however, vital that the installer of replacement windows has a full understanding of the construction and history of traditional wooden frames. This will enable them to make appropriate suggestions for energy efficiency improvements and other technological advancements that won't affect the appearance of an historic building. Anyone who installs replacement windows should be registered under a Competent Persons Scheme, such as FENSA. This will ensure that the replacements are deemed as a suitable solution under Building Regulations. A skilled carpenter can install PVC-u windows that conform to original building's character. This is especially applicable when windows are in conservation areas or listed buildings.
