Maintaining Timber Windows

A well-maintained timber window is an important part of the historic fabric of a building. It is a representation of the different materials and technologies, craftsmanship and architectural taste of the time period from which it dates.

When possible, repairs should be done in-situ. Repairing the most deteriorated areas of decay is possible with the help of specialized resin-based systems.

Durability

Timber windows were built to last for centuries. They do require some maintenance to ensure they look good. Maintenance tasks include repairs to sash cables as well as tightening the pulleys on sash, and painting. The need to upgrade timber windows to improve efficiency and energy efficiency is also increasing. This can include replacing old glazing units, repairing the window rebates that are in place or installing new cills to increase the air seal.

One of the main issues with traditional windows is damage caused by corrosion of the paintwork. This is particularly important when it comes to sash windows, as the gaps between sashes can be very large. In these circumstances water can get into the paint film and cause rotting of the putty and underlying wood. Weather conditions that are not ideal can accelerate the rotting. To avoid this windows, they should be painted regularly using a suitable exterior wood paint.

The areas that are damaged should also be repaired using a resin-based product. This will ensure that the greatest amount of the original fabric is retained. It is crucial to reduce the number of holes that are created into the frame in order to allow cable entry as these can admit moisture and cause decay.

The structural movement of the wall can cause deformations in the frame and sash. This could result in sash no longer fitting correctly, sticking or jamming in the opening and cracked glazing. This is often corrected by putting in new frames for sash made of slow-grown deal (pine) or oak. The cill should be made from a sturdy hardwood such as oak to prevent movement between the existing and new work.

To reduce the risk, there are now a variety of companies that make Boston pattern sash made of wood that can be fitted into most openings. The sash is available in a range of sizes and finishes that meet the needs of today's homeowner. These sash are combined with quadruple draft strip and improved thermal insulation can make a significant difference to the efficiency of a home's energy use.

Aesthetics

Many old timber frames have a great aesthetic appeal, since they reflect, in some shape, the materials, technology, and architectural taste from the time period they were constructed. They could also have a significant historical significance in their individual cases. This is especially true of windows that were unglazed in the early days of timber-framed buildings, where the great majority were just a collection of openings within the frame that were subdivided horizontally into mullions and vertical wood or iron bars to deter intruders.

It is crucial to maintain the appearance of traditional timber window joinery. When you spot any signs of decay caused by water penetration, it is important to stop it. This can be done by applying a thorough coat of paint, particularly in areas where there has already been damage or deterioration. It is recommended to choose paints that are intended to be used in a system (primer undercoat and finish) and to follow the manufacturer’s recommendations for preparation and number coats at each stage.

Wet rot is a common issue in older timber windows. The best method to stop it from becoming a problem is to take out any damaged or rotten parts immediately to stop the spread of the fungus responsible for it. The replacement of rotting wood must be done with care by using a slow-growing deal (pine) and, if possible, the same species as which is being removed to avoid any movement differences between the new section and existing timbers.

In the late period of the 17th century and the middle of the medieval period, glass became less expensive and more abundant, so that the glazed openings in timber-framed buildings gradually became more sophisticated with wooden tracery, moulded mullions and deep projection 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 just less prone to leaking but it also allows more expansive, clearer sheets of glass to be used in the windows than would otherwise have been possible without the need for lead lights.

Energy efficiency

Traditional timber windows offer a good energy performance due to their thickness and multi-layer construction. They also pay meticulous attention to detail. They also feature large glass areas and projecting cills that minimise air infiltration. With secondary glazing and draughtproofing the windows can be improved to increase their energy efficiency. However it is crucial to remember that such measures should be viewed in terms of the overall appearance and integrity of the original window lock repairs.

It is logical to fix or upgrade windows that are older rather than replacing them, especially when the improvements in thermal efficiency can be achieved through simple fixes. Historic windows are often considered to be of historical value because they demonstrate a variety in technological advancement and changes in architectural taste. The pressure to replace these windows are generally based on the assumption that old windows cambridge will need replacement in the near future, but most are still in a position to last for 150, 200 and even 250 years if they are properly maintained.

It is essential to realize that decay issues with traditional timber windows are easily prevented with timely and thorough repairs. Additionally it is vital to spot damp penetration issues and to remedy them quickly to prevent serious damage. Paint deterioration that occurs early could be a problem as it allows moisture to penetrate into the wood, leading to wet rot. This damage is often not evident until the paintwork is damaged or wavy but it can cause severe structural damage, and could lead to further decay.

A quality paint will prevent moisture penetration. To avoid condensation and mould it is essential to keep the paintwork as clean as possible. Modern synthetic paints are problematic because they are water-resistant and can cause mildew growth in the window frame.

The majority of windows from the past were made from timber that contained an extensive proportion of sapwood. The timbers will deteriorate quickly when exposed to moist weather, but can be protected by an extensive preservative treatment prior to when they are used. It is also essential to ensure that the type of timber used is well-suited to the climate and site conditions, as these factors can affect the longevity of the joinery. Local window manufacturers create various types of timber sash that can be adapted to fit specific historic openings. They are available in the standard Boston pattern or in custom sizes to suit the architectural style of historic buildings.

Maintenance

Regular inspections carefully redecorated, as well as timely upvc door repair door repairs; inkweapon31.Bravejournal.Net, can prolong the lifespan of windows made of timber. The main cause of decay is moisture infiltration through the deterioration of paint and putty. This can be avoided by using a quality wood preservative and painting the wood thoroughly.

It is essential that repairs to old sash and casement windows are well executed and completed with the minimum disturbance. Many of the traditional designs for timber windows can be repaired without dismantling the frame, and this option should be followed whenever possible. Loose or peeling paint should be removed with care and sanded lightly to improve the "key" of the surface and facilitate an easier adhesion of the new coating. It is important to avoid stripping old paint layers that might have historical significance If these are present it is recommended that a study of the paint be carried out.

If a portion of wood is decayed, the best solution is to remove it and replace it with timber inserts shaped to match the existing profiles. The wood that is inserted should be treated with wood preservative and the connection between the timber cill and sub-cill for masonry should be sealed.

Replacement of traditional windows using PVC-u may 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 essential that the person installing replacement windows has a full knowledge of the construction and history of traditional wooden frames. This will enable them to make the appropriate suggestions for energy efficiency improvements and other technical improvements that won't harm the historic character of a building. Those who provide replacement windows must be registered under a Competent Persons Scheme such as FENSA. This will ensure that replacement windows are approved under Building Regulations as a suitable option. It is, of course, possible for an experienced and skilled carpenter to install PVC-U windows that are sympathetic to the the building originally. This is especially true when windows are situated in listed buildings and conservation areas.
