Maintaining Timber Windows

A well-maintained wooden window is an essential part of a historic building. It is a representation of the different materials and technologies design, craftsmanship and aesthetics of the period that it was built in.

When repairs are feasible to existing windows are required, they should be made in situ. Repairing the most severe areas of decay can be accomplished with the help of specialized resin-based systems.

Durability

The windows made of timber in many historic buildings were built to last for hundreds of years. But, they have to be maintained to keep them looking great and working correctly. Maintenance tasks include sash cord repairs and retightening sash pulleys and painting. There is also a rising demand for upgrading timber windows to increase the efficiency of energy. This may include replacing old glazing units, repairing the window rebates that are in place or installing new cills to increase the air seal.

A key problem with traditional windows is the damage caused by corrosion of the paintwork. This is particularly important when it comes to sash windows, as the gaps between sashes may be extremely large. In these cases water can get into paint film and cause rotting to the wood or putty underneath. Weather conditions that are not ideal can accelerate the decay. To avoid this windows from becoming rotten, they must be regularly painted with an exterior wood paint that is suitable.

In addition to repainting, areas that have corroded must be repaired using an adhesive-based repair product. This will ensure that the maximum amount of original fabric is retained. It is crucial to reduce the number of holes created into the frame in order to allow cable entry, since they can let in moisture and cause decay.

The wall's structural movement can also lead to deformations in the frame and the sash windows cambridge. This could result in the sash not fitting properly, jamming or sticking in the opening, and Cambridge even broken glass. This can be corrected often by fitting new sash frames made of slow-grown deal (pine), or oak. The cill should be constructed from a sturdy hardwood such as oak to avoid any movement between the existing and new work.

There are several companies that manufacture Boston pattern wooden sash to fit in with the majority of openings. The sash is available in a range of sizes and finishes to meet the needs of today's homeowner. 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

Many old timber windows have a great aesthetic value because they typically show, in a particular way, the materials and technology and architectural style of the period from which they originate. They could have significant historical value on their own. This is especially true of early windows that were not glazed in timber framed buildings which were just a collection of openings in the frame, which were divided horizontally into mullions and iron or wood bars to deter intrusions.

It is important to maintain the appearance of traditional timber window joinery. As soon as you see any signs of decay caused by the penetration of moisture it is crucial to stop it. This is best accomplished by applying a thorough coat of paint, particularly in areas where there has already been damage or degradation. It is advisable to use paints specifically designed to be used as part of a system (primer undercoat, finish) and follow the manufacturer's instructions regarding preparation and the amount of coats needed at each stage.

Wet rot is a common issue in older timber windows. The best method to stop it from developing is to remove sections that are damaged or rotten as soon as possible to prevent the spread of the fungus that causes it. Replace rotting wood with slow-growing deal (pine) and, when possible, the exact kind of timber as the one being removed to prevent any differential movement.

In the late period of the 17th century and the middle of the medieval period, glass became cheaper and more abundant, so that the glazed openings in timber-framed buildings gradually became more sophisticated with wooden tracery as well as moulded mullions and protruding cills. In recent years, double glazing in cambridge was pinned into frames that were rebated with glazing sprigs rather than lead cames. This method of glazing not only makes windows less likely to leak and break, but also allows more clear glass sheets to be employed than would be possible otherwise without the use of lead lights.

Energy efficiency

Traditional timber windows offer a good energy performance due to their thickness and multi-layer construction, as well as careful attention to detailing. The large glass areas, the deep projecting cills, and the large glazing areas help to reduce air infiltration. Windows can be designed to increase their energy efficiency by draught-proofing and secondary glazing. However it is crucial to remember that such measures must be considered in terms of the overall quality and appearance of the window in its original form.

It is logical to fix or upgrade windows that are older rather than replacing them, especially when the improvements in thermal efficiency can be made through simple repairs. Historic windows are often of historical significance, since they reflect a variety of technological advancements and changes to the architectural style. The pressure to replace these windows are typically based on the assumption that the windows that are old will need to be replaced in the near future, however most are still capable of serving for 150, 200 and even 250 years, if properly maintained.

It is essential to realize that decay problems with traditional timber windows are avoidable with timely and glazed thorough repairs. In addition it is crucial to identify damp penetration problems and to remedy them quickly to avoid serious damage. The early deterioration of paint could be a problem as it allows moisture to get into the wood, which can cause wet rot. The damage is usually not apparent until the paintwork becomes cracking or wavy, but can cause significant structural damage, and could lead to further decay.

A high-quality paint will prevent this moisture penetration. 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 grow within the window frame.

The majority of older windows were constructed from sapwood-rich wood. These timbers deteriorate quickly if exposed to rain, however they can be preserved with an extensive preservation treatment prior to use. It is essential to select the appropriate type of wood for the location and the climate, since these factors can affect the durability of the joinery. Local window manufacturers offer various types of sash timbers that can be customized to fit historic openings. They can be made in the standard Boston pattern or in custom sizes to fit the architectural style of historic buildings.

Maintenance

Regular inspection carefully redecorated, as well as prompt repairs can extend the life of wooden windows. The most common reason for decay is moisture intrusion through deteriorated paint and putty. This can be avoided by using a good wood preservative and painting the wood thoroughly.

It is crucial that repairs to old sash and casement windows are properly executed, and carried out with minimal disruption. A lot of traditional wooden window designs are repairable without removing the frame, and this approach should be followed whenever feasible. Paint that is peeling or loose should be removed carefully and sanded lightly to increase the 'key' of the surface and allow for a better adhesion of the new coating. It is crucial to avoid removing old paint layers, which may have historical significance.

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

Replacement of windows made of traditional PVC-u is an appealing option, particularly when the installer provides an "all-in-one" installation service that can handle removal and replacement within one day. However, it is essential that the person installing windows replacement has a thorough knowledge of the construction and history of traditional timber frames. This will enable them to make appropriate suggestions for improvements to energy efficiency and other technical upgrades that do not alter the character of a historic building. The window installers who provide replacement windows must be registered with a Competent Persons Scheme like FENSA. This will ensure that the replacements are approved as a suitable solution under Building Regulations. It is quite possible for an experienced and skilled carpenter to install PVC-u windows that match the the building originally. This is especially relevant when windows are in conservation areas or listed buildings.
