Maintaining Timber Windows

A well-maintained wooden window is an important element of a building that is historic. It is a representation of the various materials and techniques, craftsmanship and architectural taste of the time period that it was built in.

If it is possible, repairs must be done in-situ. Repairing the most deteriorated areas of decay can be done using proprietary resin-based systems.

Durability

The windows made of timber in many old buildings were built to last for hundreds of years. They do require maintenance to keep them looking good. Maintenance tasks include repairs to sash cords as well as tightening the pulleys for sash and painting. The demand for upgrading timber windows to improve efficiency and energy efficiency is also increasing. This may 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 sash windows are concerned as the gaps between sashes can be extremely large. In these situations, water can penetrate the paint film and cause rotting of the putty and the wood underneath. The weather can be a factor in accelerating the decay. To avoid this windows from becoming rotten, they must be painted regularly using a suitable exterior wood paint.

Corroded areas should also be repaired using a resin-based product. This will ensure that the maximum amount of the original fabric is preserved. It is essential to limit the number of holes that are made into the frame to allow cable access, as these can admit moisture and cause decay.

Another issue with older windows is structural movement in the wall which can lead to deformation of the frame and the sash. This could result in the sash fitting incorrectly and jamming or sticking into the opening, or breaking glass. This can be fixed frequently by fitting new sash frames made of slow-growing deal (pine) or oak. The cill should be constructed of a strong 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 a number of companies who produce Boston pattern sash made of wood that will fit most existing openings. The sash is available in a range of sizes and finishes to meet the requirements of the modern homeowner. These new sash, when combined with quadruple draft strips and a better thermal insulation, can significantly improve the efficiency of a home's energy use.

Aesthetics

Many old timber windows have a high aesthetic value because they typically show, in a particular way the materials and techniques and architectural style of the period from which they date. They could also have a significant historical significance in their in their own right. This is particularly true for early windows that were not glazed in timber-framed structures, where the majority of them were series of openings within structural frames that were subdivided horizontally by mullions and vertical wood or iron bars in order to keep out intrusions.

Traditional window repairs near me joinery made of timber is a beautiful feature of a building and it is important to maintain its appearance. When you spot any decay caused by the penetration of moisture it is crucial to stop it. It is best to do this through thorough painting, especially if there is damage or deterioration. It is recommended to use paints designed to be used in a system (primer undercoat and finish), and to follow the manufacturer's guidelines for preparation and number coats at each stage.

Wet rot is a frequent issue in older timber windows. The best method to stop it from growing is to eliminate sections that are damaged or rotten as soon as you can to stop the spread of the fungus responsible for it. Replace rotting wood with slow-grown deal (pine), and if possible, the same type of timber as the one being removed, to avoid differential movement.

Glass became less expensive and more abundant during the late medieval period and into the 17th century. This led to the glazed openings in timber-framed homes were more elaborate, with moulded mullions, tracery made of wood and cills that protruded deep. In recent times, glass was fixed into 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 more expansive clearer, more transparent sheets of glass to be used in windows than would otherwise have been possible without the need for lead lights.

Energy efficiency

Traditional timber windows provide a good energy performance due to their thickness and multi-layer construction. They also pay attentive attention to detail. The large glass surfaces, the deep projecting cills and large glazing areas help to reduce air infiltration. The windows can be made to increase their energy efficiency through draughtproofing and secondary glazing. It is important to remember that these measures need to be taken into consideration in relation to the overall appearance and integrity of the original windows.

It makes sense to fix or upgrade windows that are older rather than replacing them, particularly when improvements in thermal efficiency can be made by simple repairs. The windows that are historic have a lot considered to be of historical value because they show a range in technological advancements and changes to architectural taste. The pressure to replace these windows are typically based on the assumption that the old windows will need replacement in the near future, however most are still capable of serving for 150, 200 and even 250 years if they are properly maintained.

It is important to recognize that decay problems with traditional timber windows can be avoidable with quick and thorough repairs. Additionally it is crucial to spot damp penetration issues and address them swiftly to avoid major damage. Early paint deterioration is a major issue, since it allows moisture penetrate the wood and cause wet rot. The damage is usually not evident until the paintwork becomes wavy or cracked however, it can cause serious 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. The use of modern synthetic paints can be problematic, as they are often formulated to be water-resistant, and this can result in the formation of mildew inside the upvc door repair window lock repair (related internet page) frame.

Most older windows were made from sapwood-rich timber. The timbers will deteriorate rapidly if exposed to rain, however they can be preserved with an extensive preservation treatment prior to use. It is important to choose the appropriate type of wood for the site and climate, as these factors will affect the durability of the joinery. Local window repairs cambridge manufacturers provide a wide range of timber sash which can be adapted to fit historical openings. They can be made in the standard Boston pattern or in custom sizes that can be adapted to historical buildings.

Maintenance

Regular inspections, careful redecoration, and prompt repairs can extend the lifespan of windows made of timber. The main reason for the decay is moisture intrusion through deteriorated paint and putty. This can be prevented by using a high-quality wood preservative and thoroughly painting the wood.

Repairs to old sash windows as well as frameless casement windows should be handled with care and minimal disruption. A lot of traditional wooden window designs can be repaired without removing the frame, and this option should be followed whenever possible. Remove peeling or loose paint and lightly sand the area to improve the 'key" of the surface. This will enable the new coating to adhere better. It is important to avoid removing old paint layers, as they may have historical significance.

Where a section of timber has become rotten the best course of action is to take out the rotten material and replace it with spliced-in inserts that are shaped to fit the existing profiles. The timber that is inserted should be treated using wood preservative. The junction between masonry sub-cill and timber cill should be sealed.

It is tempting to replace traditional windows with PVC U, particularly if the installer offers an all-in-one installation that includes removal and replacement within a single day. It is crucial that installers of replacement windows have a deep understanding of the history and design of traditional timber frames. This will allow them to make the right 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 that the replacements are deemed as a suitable option under Building Regulations. A skilled carpenter can put in PVC-u windows that are suited to original building's character. This is particularly true where the windows are located in listed buildings or conservation areas.
