Maintaining Timber Windows

A well-maintained wooden window is a crucial part of a historic building. It reflects, in various degrees, the technology and materials of the time period it was constructed, the craftsmanship and architectural taste.

If it is possible, repairs must be done in-situ. Repairing the most severe areas of decay can be done with the help of specialized resin-based systems.

Durability

Timber windows were built to last for centuries. They do require maintenance to keep them looking great. The most frequent maintenance tasks include repairs to sash cords as well as tightening sash pulleys and painting. The demand for upgrading timber windows in order to increase efficiency in energy use is also growing. This could mean replacing old glazing units, repairing existing window rebates or putting up new cills for improved air sealing.

One of the main issues with traditional windows is the damage caused by the corrosion of the paintwork. This is especially true in the case of sash windows, as the gaps between sashes can be quite large. In these circumstances water may get through the paint film and cause rotting of the putty and the wood underneath. Weather conditions that are not ideal can accelerate the decay. To stop this from happening windows from becoming rotten, they must be painted regularly with a suitable exterior wood paint.

In addition to repainting, corroded areas should be repaired with an adhesive-based repair product. This will ensure the maximum amount of original fabric retained. It is essential to limit the number of holes created in the frame to allow cable access, since they can let in moisture and cause decay.

Another major issue with older windows is the structural movement within the wall, which could cause deformation of the frame and the sash. This can result in the sash fitting incorrectly jamming, sticking or sagging in the opening, or breaking glass. This can be corrected often by putting in new frames for sash made of slow-growing deal (pine), or oak. The cill should be constructed of a durable hardwood like oak to avoid differential movement between the old and new work.

To help reduce this problem There are several companies that produce Boston pattern wooden sash that will fit into the majority of existing openings. They are available in a range of sizes and finishes to suit the needs of today's homeowner. In conjunction with quadruple draught strip and better thermal insulation these new sash can make an enormous difference to the energy efficiency of a house.

Aesthetics

Many old wooden cambridge windows and doors have an excellent aesthetic value as they often demonstrate, in a way the materials and technologies and architectural style of the period from which they originate. They may also have a significant historic value in their individual cases. This is particularly true of early windows that were not glazed in timber-framed structures, where the majority were series of openings in structural frames that were subdivided horizontally by mullions, and vertically by iron or wood bars in order to protect against intruders.

Traditional timber window joinery is a beautiful feature of a building and it is important to keep its appearance. As soon as you see any signs of decay caused by moisture penetration it is essential to stop it. It is recommended to do this by thorough painting, especially if there is damage or degradation. It is recommended to use paints specifically designed to be used as part of a system (primer as well as undercoat, finish and primer) and follow the manufacturer's instructions in relation to preparation and the amount of coats required at each stage.

Wet rot is a common issue in old timber windows. The best way to stop it developing is to remove any damaged or rotten parts as soon as you can to prevent the spread of the fungus that causes it. Replace rotting wood with slow-growing deal (pine) and, when possible, the exact type of timber as the one that is being removed to prevent the possibility of differential movement.

Glass became cheaper and more abundant in the late medieval era and into the 17th century. This led to glazed openings on timber-framed houses became more complex with moulded mullions, tracery made of wood and deep cills projecting into the air. In recent years, glazing was fixed into frames that were rebated using glazing sprigs rather than 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 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 attention to the smallest of details. The large glass areas, the deep projecting cills, and the large glazing areas help to reduce air infiltration. With secondary glazing and draughtproofing, windows can be upgraded to improve their energy efficiency. However it is essential to keep in mind that these measures should be viewed in relation to the overall appearance and integrity of the window repair near me in its original form.

It is sensible to fix or upgrade windows, rather than replacing them, particularly when improvements in thermal efficiency can be achieved by simple repairs. Historic windows often have historical significance that demonstrates a range of technological advancement and changes in architectural style. Many people believe that these windows will need to be replaced in the near future. However, most will last for 150, 200 or even 250 years with proper maintenance.

It is important to recognise that the decay issues associated with traditional windows made of timber can be avoided by thorough maintenance and timely repairs. In addition it is crucial to identify damp penetration problems and address them swiftly to prevent serious damage. Early deterioration of paint is a major problem because it allows moisture to penetrate the wood and cause wet rot. This type of damage is typically not noticed until the paintwork is damaged or wavy but it can cause severe structural damage and can lead to further decay.

A quality paint will block moisture penetration. It is also necessary to keep the paintwork clean in order to prevent mould and condensation. The use of modern synthetic paints can pose a problem, as they are often designed to be water-resistant which can lead to the formation of mildew in the Skylight window Replacement frame.

The majority of older windows were manufactured from timber containing the majority of sapwood. These timbers deteriorate quickly if exposed to rain, however they can be preserved with a thorough preservation process prior to use. It is crucial to select the right kind of wood for the location and climate, as these factors can affect the durability of the joinery. Local window lock repairs manufacturers create a range of sash made of timber that can be tailored to fit specific historic openings. They are available in the standard Boston pattern or in custom sizes that can be adapted to the architectural style of 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 infiltration through deteriorated paint and putty. This can be avoided by using a quality wood preservative and painting the wood thoroughly.

It is important that repairs to old sash and casement windows are well executed and done with minimal disruption. Many traditional timber window installation cambridge designs are repairable without removing the frame, and this method should be followed whenever feasible. Loose or peeling paint must be removed with care and sanded lightly to increase the "key" of the surface and facilitate an improved adhesion of the new coating. Be careful to avoid stripping old paint layers that could have historical value and if they are present, it is recommended that a paint analysis be carried out.

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

It's tempting to replace traditional windows with PVC u, particularly if the installer offers an installation that includes removal and replacement within a single day. It is essential that the person installing windows replacement has a thorough knowledge of the structure and history of traditional wooden frames. This will allow them to make the appropriate suggestions for energy efficiency improvements and other technical improvements that do not alter the historical character of a building. Those providing 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. A skilled carpenter can put in PVC-u windows that conform to the original character of the building. This is particularly true where windows are situated in listed buildings and conservation areas.
