Maintaining Timber Windows

A well-maintained wooden window is an essential component of a historical building. It reflects in different levels, the materials and technologies of the time in which it was made, the craftsmanship and architectural taste.

Whenever possible repairs to windows that are already in use should be made in situ. Repairing the worst areas of decay can be accomplished using proprietary resin-based systems.

Durability

Timber windows were made to last for hundreds of years. But, they have to be maintained to keep them looking good and functioning properly. Maintenance tasks include repairs to sash cables, retightening of pulleys for sash and painting. The need to upgrade windows made of timber to increase efficiency in energy use is also growing. This may include replacing old glazing units, fixing existing window rebates, or installing new cills for improved air door seal repair near me.

A key problem with traditional windows is damage caused by corrosion of the paintwork. This is particularly true when windows made of sash are involved because the gaps between the sashes can be quite wide. In these cases water can get into paint film and cause rotting of the wood or putty beneath. The weather can be a factor in accelerating the decay. To avoid this windows, they should be painted regularly using a suitable exterior wood paint.

In addition to repainting, areas that have corroded should be repaired with an adhesive-based repair product. This will ensure that the maximum possible amount of the original fabric is preserved. It is also essential 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 and sash. This can lead to sash not fitting correctly, jamming or sticking in the opening, and broken glass. Most often, this is corrected through the installation of new sash boxes that have been constructed from slow-growing deal (pine) or oak. The cill needs to be constructed of a durable hardwood, like oak, in order to prevent any the movement of new and older work.

To alleviate this issue to reduce the risk of this happening, there are a variety of companies that make Boston pattern wooden sash that will fit most existing openings. They are available in a range of sizes and finishes to suit the needs of the modern homeowner. These new sash, when combined with quadruple draft strip and a better thermal insulation, can make a huge difference to the efficiency of a home's energy use.

Aesthetics

A lot of old timber frames have a high aesthetic appeal because they reflect, in some form, the materials, technology, and architectural taste from the time period they were built. They could have significant historical value in their own right. This is particularly true of early unglazed windows in timber-framed buildings, where the majority were series of openings in frames of structural construction, which were divided horizontally by mullions, and vertically by iron or wood bars in order to keep out intruders.

It is crucial to maintain the appearance of traditional wooden window repair joinery. It is crucial that any decay caused by water penetration is removed as soon as it is discovered. This is best done by a thorough painting process, especially in areas where there has already been damage or degradation. It is recommended to choose paints that are intended to be used in a set (primer undercoat and finish) and follow the manufacturer's guidelines for preparation and number coats at each stage.

Wet rot is a typical problem for old timber windows and the best way to stop it developing is to remove any damaged or rotten sections as soon as possible to stop the spread of the fungus that causes it. The replacement of rotting wood should be done with care and with a slow-growing deal (pine) and, whenever possible using the same species as which is being removed to prevent shifting between the new section and the existing timbers.

In the late period of the 17th century and the middle of the medieval period, glass became less expensive and more plentiful so that glazed openings in timber-framed buildings gradually became sophisticated, with tracery made of wood moulded mullions, moulded mullions, and deep projection cills. Increasingly, the glazing was set within rebated frames and pinned in by 'glazing sprigs' rather than being inserted into lead cames. This method of glazing is not just less prone to leaking but it also allows more expansive and clearer sheets of glass to be used in windows than would be possible without the need for leaded lights.

Energy efficiency

The traditional timber windows are energy efficient due to their thickness, multilayer construction and attention to detail. The large glass surfaces, the deep projection cills and wide glazing areas help to reduce air infiltration. With secondary glazing and draughtproofing, windows can be upgraded to increase their energy efficiency. However it is essential to remember that such measures should be evaluated in terms of the overall appearance and integrity of the window repair cambridge in its original form.

Therefore, keeping existing historic windows that require repair rather than replacing them makes sense, particularly when their thermal improvements can be achieved inexpensively with simple repairs and improvements. Historic windows are often of historical value, as they demonstrate a variety in technological advancements and changes to the architectural style. The pressure to replace these windows are typically based on the assumption that windows that are old will need to be replaced in the near future, but the majority of them are capable of providing service for 150, 200 or even 250 years, if properly maintained.

It is essential to understand that the decay issues that are typical of timber windows can be prevented by thorough maintenance and prompt repairs. It is also crucial to identify damp problems and fix them quickly so that you can avoid serious damage. Early paint deterioration can be a problem because it allows moisture to penetrate into the wood, leading to wet rot. It is not uncommon for this damage to go unnoticed until the paintwork begins to crack or become curly. However, it could cause structural damage and lead to further decay.

A good quality paint will prevent this moisture from entering. It is also important to keep the paintwork spotless in order to prevent mould and condensation. Modern synthetic paints pose a challenge since they are usually water-resistant and can cause mildew to develop in the window repair specialists frame.

Most older windows were made from sapwood-rich timber. These timbers can deteriorate very rapidly if exposed to wet weather conditions, but they can be preserved with a thorough preservative treatment before they are used. It is important to choose the right kind of wood for the site and the climate, since these factors can affect the longevity of the joinery. Local window supplier cambridge manufacturers produce a range of sash made of timber that can be adapted to fit specific openings in historic buildings. They can be made to the standard Boston pattern dimensions or to specific sizes that are in keeping with the architectural style of historic buildings.

Maintenance

Regular inspection as well as careful redecoration and quick repairs can prolong the lifespan of windows made of timber. The most common reason for the decay is the infiltration of moisture through the deterioration of paint and putty. This can be prevented by using a high-quality wood preservative and painting the wood thoroughly.

It is crucial that repairs to the old sash and casement windows are well executed and done with the minimum disturbance. A lot of traditional wooden Window seal repairs designs 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 surface to improve the "key" of the surface. This will allow the new coating to stick better. It is important to avoid removing old paint layers that may have historical significance.

When a section of wood has rotted the best option is to take it off and replace it with timber inserts that are shaped to match the existing profiles. The inserted timber should also be treated using wood preservative, and the joint between masonry sub-cills and timber cill should be sealed.

Replacement of windows made of traditional PVC-u can be a tempting option, especially when the installer offers a "one-stop shop" installation service that can handle removal and replacement within a day. It is important that the installers of replacement windows have a thorough understanding of the history and construction of traditional timber frames. This will enable them to make appropriate recommendations for energy efficiency improvements as well as other technological upgrades that won't alter the appearance of a building that is historic. Those providing replacement windows 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. A skilled carpenter can install PVC-u windows that conform to original building's character. This is particularly relevant when windows are located within conservation areas or listed buildings.
