Maintaining Timber Windows

A well-maintained wooden windows cambridge window is an important element of a building that is historic. It is a representation of the various materials and techniques, craftsmanship and architectural taste of the time period from which it dates.

Whenever possible repairs to existing windows should be done in situ. The repair system that is based on resin can be used to repair the most damaged areas of decay without having to remove the entire window.

Durability

Timber windows were designed to last hundreds of years. But, they have to be maintained to ensure that they look good and operating properly. Maintenance tasks include repairs to sash cables and retightening pulleys on sash, and painting. There is a growing need to upgrade the timber windows to improve energy efficiency. This may mean replacing old glazing units, fixing existing window rebates or putting in new cills for better air sealing.

The corrosion of paintwork is a major issue with traditional windows. This is particularly important when windows made of sash are involved because the gaps between sashes can be quite large. In these cases water can enter the paint film and cause rotting to the wood or putty underneath. The rotting process can be made worse by poor weather conditions. To prevent this windows from becoming rotten, they must be painted regularly with an exterior wood paint that is suitable.

Corroded areas should be repaired using a resin-based product. This will ensure that the maximum possible amount of the original fabric is preserved. It is also necessary to minimise the number of holes drilled into the frame to allow cable entry, as they could allow water in and cause decay.

Another significant problem with older windows is the structural movement within the wall that can cause deformation of the frame and the sash. This can result in sash no longer fitting correctly or sticking or jamming into the opening and broken double glazing repairs near me. This can often be fixed through the installation of new sash boxes that have been made from slow grown deal (pine) or oak. The cill should be constructed of a strong hardwood such as oak, in order to prevent any differential movement between new and older work.

To reduce the risk, there are now a variety of companies that produce Boston pattern wooden sash that will fit most existing openings. The sash is available in a variety of sizes and finishes to fit the needs of modern-day homeowners. These new sash, when coupled with quadruple draft strips and improved thermal insulation can make a significant difference to the energy-efficiency of a home.

Aesthetics

A lot of old timber frames possess a dazzling aesthetic appeal because they show, in some shape, the materials technology, design, and aesthetics of the time they were constructed. They could have significant historical value in their own right. This is particularly true for windows that were unglazed in the early days of timber-framed buildings, in which the majority were series openings in structural frames subdivided horizontally by mullions, and vertically by wood or iron bars to protect against invaders.

Traditional window joinery made of timber can be a highly decorative element of a structure and it is important to keep its appearance. It is crucial that any decay caused by water penetration is stopped as soon as it is discovered. This can be done by painting thoroughly, especially in areas in which there is already damage or deterioration. It is recommended to use paints that are designed to be used as part of the system (primer, undercoat and finish) and follow the manufacturer's instructions in relation to preparation and number of coats required at each stage.

The fungus responsible for wet rot can spread quickly in old timber windows. To prevent this, take out any damaged or rotten parts as quickly as you can. The replacement of rotting timber must be done with care using slow grown deal (pine) and, wherever possible it is the same species as which is being removed to avoid shifting between the new section and the existing timbers.

Glass became more affordable and abundant in the late medieval era and into the 17th century. This led to double glazed door repairs openings on timber-framed houses were more elaborate, with moulded mullions, tracery made of wood and deep projecting cills. In recent times, glass was fixed to frames that were rebated with glazing sprigs rather than lead cames. This method of glazing is not just less susceptible to leaks, but it can allow for larger clearer, more transparent sheets of glass to be used in windows than would otherwise be possible without the need for leaded lights.

Energy efficiency

Traditional timber windows are energy efficient because of their thickness, multilayer construction and attention to the smallest of details. They also have large glass areas as well as deep projecting cills that reduce air infiltration. The windows can be made to increase their energy efficiency through draughtproofing and secondary glazing. It is important to keep in mind that these measures should be taken into consideration in relation to the overall integrity and look of the original windows.

It is sensible to fix or upgrade windows, rather than replacing them, particularly when improvement in thermal efficiency can be made through simple repairs. Older windows are usually considered to be of historical value because they show a range in technological advancement and changes in the architectural style. Many people believe that the windows will need to be replaced in the near future. However, most are still in service for 150, 200 or even 250 years with proper maintenance.

It is important to recognise that the decay issues caused by traditional timber windows can be prevented by regular maintenance and timely repairs. It is also important to identify damp problems and fix them quickly to avoid major damage. Early paint deterioration could be a problem as it allows moisture to penetrate into the wood, leading to wet rot. It is not uncommon for this issue to go undetected until the paintwork starts to crack or turn wavier. However, it can cause structural damage and lead to further decay.

A high-quality paint will prevent this moisture penetration. To prevent condensation and mould it is essential to keep the paintwork as clean as possible. The use of modern synthetic paints can be problematic because they are usually formulated to be water-resistant, which can cause the growth of mildew in the window Repairs near me frame.

The majority of older windows were constructed from sapwood-rich wood. These timbers are susceptible to deterioration quickly when exposed to wet weather, but can be protected with an extensive preservative treatment prior to when they are put to use. It is important to choose the right type of wood for your location and the climate, since these factors can affect the durability of the joinery. Local window manufacturers offer various types of timber sash which can be adapted to fit historical openings. They can be constructed according to the standard Boston pattern dimensions, or to custom sizes that are in keeping with the architectural style of historic buildings.

Maintenance

The life span of windows made from timber can be extended significantly by regular inspection as well as a careful redecoration and prompt repair. The primary reason for decay is moisture infiltration through deteriorated putty and paint. This can be avoided by using a quality wood preservative and painting the wood thoroughly.

Repairs to sash windows that are old and casement upvc window and door repairs frames should be done with care and minimal disruption. Many of the traditional designs for timber windows are repairable without removing the frame, and this approach should be used whenever it is possible. Peeling or loose paint should be removed carefully and sanded lightly to improve the 'key' of the surface and facilitate a better adhesion of the new coating. Care should be taken to avoid stripping old paint layers which may have historic value If these are present, it is recommended that a study of the paint be carried out.

When a piece of wood has begun to decay, the best option is to eliminate the rotten material and replace it with spliced-in inserts that are shaped to match existing profiles. The wood that is inserted should be treated with a wood preservative and the joint between the timber cill and masonry sub-cill should be sealed.

It can be tempting to replace traditional windows with PVC U, particularly if the installer offers an 'all-in-one' installation which includes both replacement and removal within a single day. It is essential that the person installing replacement windows has a complete knowledge of the structure and history of traditional wooden frames. This will enable them to make the right recommendations for energy efficiency improvements and other technical upgrades that will not harm the historic character of a building. The windows that are replaced should be registered with a Competent Persons Scheme like as FENSA. This will ensure that the replacements are deemed as a suitable option under Building Regulations. A skilled carpenter can install PVC-u windows that conform to original building's character. This is particularly true where the windows are located in listed buildings or conservation areas.
