Maintaining Timber Windows

A well-maintained wooden window is an essential component of a historical building. It demonstrates in various degrees the various materials and techniques, craftsmanship and architectural taste of the time period that it was built in.

If repairs are possible to existing windows are required, they should be carried out in situ. The upvc door repair cost system that is based on resin can be used to fix the worst areas of decay without removing the whole window.

Durability

Timber windows were made to last hundreds of years. They require regular maintenance to ensure they look good. Maintenance tasks include repairs to sash cables, retightening of pulleys for sash and painting. The demand for enhancing timber windows in order to improve efficiency in energy use is also growing. This could include replacing old glazing units, fixing existing window rebates or installing new cills to increase the air seal.

One of the major issues with traditional windows is the damage caused by the corrosion of the paintwork. This is particularly important when windows with sash are involved since the gaps between the sashes can be quite large. In these situations, water can penetrate the paint film and cause rotting of the putty as well as the wood underneath. The rotting may be further aggravated by poor weather conditions. To stop this from happening, windows must be painted regularly with an exterior wood paint.

In addition to repainting, areas that have corroded must be repaired using a resin-based repair product. This will ensure that the highest possible amount of the original fabric is retained. It is also essential to reduce the number of holes you drill into the frame to allow cable entry, as they could admit water and lead to decay.

The wall's structural movement can also lead to distortions in the frame and sash. This can result in the sash not fitting properly and jamming or sticking to the opening and cracked double glazing repairs cambridge. This can be corrected often by putting in new sash frames constructed of slow-growing deal (pine), or oak. The cill should be made from durable hardwood such as oak to avoid any movement between the old and new work.

There are several companies that manufacture Boston pattern wooden sash to fit into the majority of existing openings. The sash is available in a variety of sizes and finishes that meet the needs of today's homeowner. Combined with quadruple draught strips and improved thermal insulation, these new sash can make a substantial difference to the energy efficiency of a home.

Aesthetics

Many old timber windows have a great aesthetic value as they often demonstrate, in a way the materials and technologies and architectural style of the time in which they date. They may also have a significant historic value in their own right. This is especially true of early windows that were not glazed in timber-framed buildings, where the majority of them 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 invaders.

Traditional timber window joinery can be a stunning aspect of a building, and it is important to maintain its appearance. As soon as you see any decay caused by the penetration of moisture, it is important to stop it. This is best done by applying a thorough coat of paint, particularly in areas where there has already been 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 stop this from happening, remove any rotten or damaged parts as promptly as you are able to. The replacement of wood that is rotting should be carefully undertaken using slow grown deal (pine) and, if feasible, the same species as which is being removed to prevent shifting between the new and old timbers.

In the late period of the 17th century and the middle of the medieval period, glass became cheaper and more plentiful so that glazed openings in timber-framed structures gradually became more elegant with wooden tracery as well as moulded mullions and projecting cills. In recent times, glass was fixed to frames that were rebated with glazing sprigs rather than lead cames. This method of glazing is not only less susceptible to leaks, but it also allows much wider clearer, more transparent sheets of glass to be used in the windows than would have been possible without the need for leaded lights.

Energy efficiency

Traditional timber windows are energy efficient because of their thickness, multilayer construction and attention to detail. They also feature large glass areas as well as deep projection cills which reduce air infiltration. With secondary double glazing seal repairs and draughtproofing, windows can be made more efficient to increase their energy efficiency. However, it is important to remember that such measures should be evaluated in the context of the overall appearance and integrity of the original Window mechnism repair.

Therefore, keeping old windows that require repair rather than replacing them is logical especially when their thermal improvements can be achieved inexpensively with simple repairs and improvements. Older windows are usually considered to be of historical value because they reflect a variety of technical development and changes to architectural taste. The pressures to replace these windows are usually based on the assumption that windows that are old will need to be replaced in the near future, but they are capable of serving for 150, 200 and even 250 years if they are properly maintained.

It is crucial to understand that decay problems with traditional timber windows are avoidable with prompt and thorough repairs. It is also important to identify damp problems and address them promptly so that you can avoid serious damage. Early paint deterioration is a concern because it allows moisture to get into the wood, causing wet rot. It is not uncommon for this type of damage to go undetected until the paintwork begins to crack or become curly. However, it could cause structural damage and then further decay.

A good paint will block moisture penetration. To prevent condensation and mould it is crucial to keep the paintwork as clean as it can be. The use of modern synthetic paints can pose a problem because they are usually formulated to be water-resistant, and this can lead to the formation of mildew within the window frame.

Most older windows were made from sapwood-rich timber. These timbers are susceptible to deterioration quickly when exposed to moist weather, however they can be protected by a thorough preservative treatment before they are used. It is also crucial to ensure that the kind of timber used is well-suited to the site and climate conditions, since these factors affect the durability of the joinery. Local window manufacturers offer an array of sash made from timber that can be made to fit the historic openings. They can be built to the standard Boston pattern dimensions or to specific dimensions that are compatible with the historic architecture.

Maintenance

The lifespan of windows made of timber can be extended significantly by regular inspection carefully redecoration, and prompt repair. The primary cause of decay is the infiltration of moisture through deteriorated putty and paint. This can be avoided with thorough painting and using a good quality wood preservative.

It is important that repairs to old sash and casement windows are done correctly and done without causing any disturbance. Many of the traditional designs for timber windows can be repaired without dismantling the frame, and this approach should be used whenever it is feasible. Remove any peeling or loose paint and lightly sand the area to improve the 'key" of the surface. This will allow the new coating to adhere better. It is crucial to avoid removing old paint layers that could have historical significance.

When a section of wood has rotted the best way to deal with it is to take it off and replace it with timber inserts designed to match the existing profiles. The inserted wood should also be treated with a wood preserver and the connection between the timber cill and the sub-cill for masonry should be sealed.

It's tempting to replace traditional windows with PVC u, particularly when the installer offers an 'all-in-one' installation which includes removal and replacement in one day. However, it is crucial that the person who installs replacement windows has a complete knowledge of the construction and history of traditional wooden frames. This will enable them to make appropriate suggestions for improvements to energy efficiency and other technical improvements that will not harm the historical character of a building. Those providing replacement windows should be registered with a Competent Persons Scheme like FENSA. This will ensure that the replacements are deemed as a suitable option under Building Regulations. A skilled carpenter is able to install PVC-u Windows that are sympathetic to original building's character. This is particularly true where the windows are located in listed buildings and conservation areas.
