Maintaining Timber Windows

A well-maintained and maintained timber window is a significant part of the historic structure of a building. It demonstrates in various degrees the various materials and techniques as well as the craftsmanship and architectural style of the period that it was built in.

Whenever possible repairs to upvc doors (https://tempaste.com/hhruYacaRfp) to existing windows are required, they should be carried out in situ. The repair system that is based on resin can be used to repair the most damaged areas of decay without removing the whole window.

Durability

The timber windows in many old buildings were built to last for hundreds of years. They do require some maintenance to keep them looking good. The most common maintenance tasks include repairs to sash cords as well as tightening sash pulleys and painting. There is also a rising demand to upgrade the timber windows to improve energy efficiency. This can involve replacing old double glazing seal repairs units, repairing existing window rebates or putting in new cills for better air sealing.

The deterioration of paintwork is a major problem with traditional windows. This is especially important where sash windows are involved as the gaps between sashes can be extremely wide. In these circumstances water may get through the paint film and cause rotting of the putty and the wood beneath. The rotting may be further aggravated by weather conditions that are not ideal. To stop this from happening, windows need to be regularly painted with an exterior wood paint.

In addition to repainting, areas that have corroded should be repaired with the help of a resin-based repair solution. This will ensure that the maximum possible amount of the original fabric is retained. It is essential to limit the number of holes made in the frame to allow cable entry because they could let in moisture and cause decay.

The wall's structural movement could also cause distortions in the frame and sash. This can result in the sash not fitting properly and jamming or sticking to the opening, and damaged glazing. This can be corrected often by putting in new sash frames made of slow-growing deal (pine), or oak. The cill must be made of a durable hardwood, like oak, to prevent shifting between the new and older work.

To reduce the risk to reduce the risk of this happening, there are several companies that produce Boston pattern wooden sash that will fit into the majority of existing openings. These sash are available in a variety of sizes and finishes that meet the requirements 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 great aesthetic appeal, since they reflect, in some form, the materials technology, design, and aesthetics of the time they were made. They also may have significant historical value in their individual cases. This is especially true of windows that were unglazed in the early days of timber-framed structures, where the majority of them were series of openings in frames of structural construction, which were divided horizontally by mullions, and vertically by wood or iron bars to keep out intrusions.

Traditional window joinery made from timber can be a highly decorative feature of a building and it is important to keep it looking good. As soon as you see any decay caused by moisture penetration, it is important to stop it. This is best accomplished by a thorough painting process, especially in areas in which there is already damage or deterioration. It is recommended to use paints designed to be used in a set (primer undercoat and finish), and to follow the manufacturer's guidelines for preparation and number coats at each stage.

The fungus responsible for wet rot can quickly spread in old windows made of wood. To prevent this from happening, remove any damaged or rotten parts as soon as you can. The replacement of wood that is rotting should be carefully undertaken by using a slow-growing deal (pine) and, whenever possible it is the same species as which is being removed to prevent differential movement between the new and old timbers.

In the late medieval and 17th century periods glass became cheaper and more abundant, and the openings for double glazed door repairs glass in timber-framed structures gradually became more elegant with wooden tracery as well as moulded mullions and protruding cills. In the past, more often, the glass was laid within rebated frames and pinned in with 'glazing sprigs' rather than into lead cames. This method of glazing is not just less prone to leaking but it can allow for larger, clearer sheets of glass to be used in windows than would have been possible without the need for leaded lights.

Energy efficiency

The traditional timber windows are energy efficient because of their thickness and multilayer construction as well as attention to detail. They also feature large glass areas and projecting cills that minimise air infiltration. With secondary glazing and draughtproofing, windows can be made more efficient to increase their energy efficiency. However it is crucial to remember that such measures should be viewed in relation to the overall appearance and integrity of the original window.

It is sensible to fix or upgrade windows that are older rather than replacing them, particularly when improvement in thermal efficiency can be achieved through simple fixes. Historic windows often have an historic value that illustrates a variety of technological advances and changes in architectural tastes. The pressures to replace such windows are typically based on the assumption that windows of the past will require replacement in the near future, however most are still in a position to last for 150, 200 and even 250 years, if properly maintained.

It is essential to realize that decay issues associated with traditional timber windows are easily prevented with timely and thorough repairs. It is also crucial to recognize damp issues and correct them swiftly to avoid major damage. The early deterioration of paint is a major problem because it allows moisture to penetrate the wood and cause wet rot. It is not uncommon for this damage to go unnoticed until paintwork begins to crack or becomes wavier. However, it could cause structural damage and lead to further decay.

A good paint will block moisture penetration. It is also necessary to keep the paintwork clean in order to prevent condensation and mould growth. Modern synthetic paints can be problematic, as they are often made to be water-resistant which can lead to the formation of mildew in the window frame.

The majority of older windows were constructed from timber with the majority of sapwood. These timbers can deteriorate very quickly when exposed to wet weather, however they can be preserved with a thorough treatment of preservative before they are put to use. It is also important to ensure that the type of timber used is well-suited to the site and climate conditions, as these factors 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 produced in the standard Boston pattern or in custom sizes that can be adapted to historic buildings.

Maintenance

The life span of windows made from timber can be extended considerably through regular inspections as well as a careful redecoration and timely repair. The most common cause of decay is the infiltration of moisture through deteriorated paint and putty. This can be prevented by thorough painting and the use of an excellent wood preservative.

Repairs to old sash windows as well as casement window frames must be done with care and with minimal disruption. It is possible to fix several traditional designs of timber windows without removing the frame. This should be done whenever possible. Remove loose or peeling paint and then lightly sand the surface to improve the "key" of the surface. This will allow the new coating to stick better. Care should be taken to avoid stripping old paint layers which could have historical value If these are present it is recommended that a study of the paint be conducted.

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

Replacement of traditional windows using PVC-u may be a tempting option, especially when the installer provides a 'one stop shop' installation that takes care of both removal and replacement within the span of a day. However, it is essential that the person installing replacement windows has a complete understanding of the construction and history of traditional timber frames. This will allow them to make the appropriate suggestions for energy efficiency improvements and other technological upgrades that won't harm the character of a historic building. Anyone who installs replacement windows must be registered under a Competent Persons Scheme, such as FENSA. This will ensure the replacements are deemed acceptable by the Building Regulations as a suitable option. It is quite possible for an experienced and skilled carpenter to install PVC-U windows that match the the building originally. This is especially true when windows are situated in listed buildings or conservation areas.
