Maintaining Timber Windows

A well-maintained timber window is a significant element of the historical structure of a building. It illustrates in varying degrees the different materials and technologies design, craftsmanship and aesthetics of the period that it was built in.

Whenever possible repairs to existing windows should be done in-situ. Repairing the worst areas of decay can be done using proprietary resin-based systems.

Durability

The windows made of wood in many historic structures were designed to last for a long time. However, they need to be maintained to keep them looking good and functioning correctly. The most frequently-asked maintenance tasks are repairs to sash-cords as well as tightening sash pulleys and painting. There is a growing need to upgrade 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.

The corrosion of paintwork is a major problem with traditional windows. This is especially true when it comes to sash windows, as the gaps between sashes may be quite large. In these situations water may get through the paint film and cause rotting of the putty as well as underlying wood. The rotting process can be made worse due to weather conditions that are poor. To prevent this from happening, windows should be painted regularly with an exterior wood paint.

Corroded areas should also be repaired using resin-based products. This will ensure that the maximum amount of original fabric is preserved. It is crucial to reduce the number of holes that are drilled into the frame in order to allow cable entry, because they could let in moisture and upvc windows Cambridge cause decay.

The structural movement of the wall can cause distortions in the frame as well as sash. This can result in the sash window repair cambridge not fitting properly and jamming or sticking into the opening, and even broken glass. Often this can be corrected through the installation of new sash boxes constructed from slow-growing deal (pine) or oak. The cill should be constructed of a durable hardwood like oak to avoid differential movement between the existing and new work.

To alleviate this issue, there are now a variety of companies that make Boston pattern wooden sash that will fit most existing openings. They are available in a variety of sizes and finishes that fit the needs of modern homeowners. In conjunction with quadruple draught strip and improved thermal insulation, these new sash can make significant improvements to the energy efficiency of your home.

Aesthetics

Many old timber windows have a high aesthetic value since they usually illustrate, in some way the materials and techniques and architectural taste of the period from which they date. They could also have significant historical value in their in their own right. This is particularly true of early unglazed windows in timber-framed buildings, in which the majority were simply a series of openings in frames of structural construction, which were divided horizontally by mullions with vertical iron or wood bars in order to protect against intruders.

Traditional window joinery made from timber can be a highly decorative feature of a building and is essential to keep its appearance. As soon as you see any signs of decay due to moisture penetration it is crucial to stop it. It is recommended to do this with thorough painting, especially where there has been damage or deterioration. It is recommended to use paints designed to be used in a set (primer undercoat and finish) and to adhere to the manufacturer's recommendations for preparation and number of coats at each stage.

Wet rot is a frequent issue in old timber windows and the best way to stop it becoming a problem is to take out sections that are damaged or rotten immediately to stop the spread of the fungus that causes it. Replace the wood that is rotting with slow-growing deal (pine) and, if possible, the same type of timber that is being removed, to prevent differential movement.

Glass became more affordable and abundant in the late medieval period and into the 17th century. This led to the openings for glazed windows on timber-framed houses became more complicated with moulded mullions, wooden tracery and deep projecting 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 not only makes windows less likely to leak, but also allows for wider sheets of clearer glass to be used than would have been feasible without the use of lead lights.

Energy efficiency

The traditional timber windows are energy efficient due to their thickness and multilayer construction as well as care for the smallest of details. The large glass surfaces, the deep projection cills and wide glazing areas help to reduce air infiltration. The windows can be modified to increase their energy efficiency with draught-proofing and secondary glazing. It is essential to remember that these measures should be taken into consideration in relation to the overall appearance and integrity of the original windows.

Therefore, keeping old windows that are in need of repair instead of replacing them is logical, particularly when their thermal enhancements can be achieved cost-effectively through simple repairs and upgrades. Older windows typically have an historic value that illustrates a variety of technological advances and changes in architectural tastes. The pressure to replace these windows are typically based on the assumption that the windows of the past will require replacement in the near future, but most are still in a position to last for 150, 200 or even 250 years if they are properly maintained.

It is essential to understand that the decay problems caused by traditional windows made of timber can be avoided by thorough maintenance and prompt repairs. In addition, it is essential to identify damp penetration problems and fix them promptly to avoid serious damage. Early paint deterioration could be a problem as it allows moisture to get into the wood, leading to wet rot. It is not uncommon for this damage to go unnoticed until the paintwork begins to crack or becomes curly. However, it can cause structural damage and then further decay.

A good quality paint will stop this moisture penetration. It is also necessary to keep the paintwork clean to avoid condensation and the growth of mould. The use of modern synthetic paints can pose a problem because they are usually made to be water-resistant and this may cause the growth of mildew in the window frame.

The majority of windows from the past were manufactured from timber containing the majority of sapwood. These timbers deteriorate quickly if exposed to rain, but they can be preserved with a thorough preservation process prior to use. It is also essential to ensure that the type of wood used is suited to the site and climate conditions, as these elements will influence the durability of the joinery. Local Window maintenance manufacturers produce a range of sash made of timber that can be tailored to fit specific historic openings. They can be built to the standard Boston pattern dimensions, or to custom sizes that are in keeping with the architectural style of historic buildings.

Maintenance

Regular inspection as well as careful redecoration and prompt repairs can extend the life of timber windows. The main reason for decay is the infiltration of moisture through deteriorated putty and paint. This can be prevented by careful painting and the use of an excellent wood preservative.

Repairs to old sash windows and frameless casement windows should be handled 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 taken whenever feasible. Peeling or loose paint should be removed with care and sanded lightly to increase the 'key' of the surface and facilitate an easier adhesion of the new coating. Be careful to avoid stripping old paint layers which could have historical value If these are present it is recommended that a paint analysis be conducted.

If a piece of timber has begun to decay, the best course of action is to remove the rotted material and replace it with spliced-in inserts that are shaped to match the existing profiles. The timber inserts should be treated with wood preservative, and the joint between masonry sub-cills and timber cill should be sealed.

Replacement-Doors-300x200.jpgIt's tempting to replace traditional windows with PVC u, particularly when the installer provides an all-in-one installation that includes both 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 the appropriate suggestions for energy efficiency improvements and other technological advancements that won't harm the character of a historic building. Those who provide replacement windows should be registered under a Competent Persons Scheme like as FENSA. This will ensure the replacements are deemed to be approved under Building Regulations as a suitable alternative. A skilled carpenter can put in PVC-u windows that are suited to the original character of the building. This is especially true when windows are installed in listed buildings and conservation areas.
