Maintaining Timber Windows

A well-maintained wooden window is an essential part of a historic building. It illustrates in varying degrees the different materials and technologies as well as the craftsmanship and architectural style of the time period from which it originates.

When upvc doors repairs are feasible to existing windows should be made in situ. Repairing the most deteriorated areas of decay is possible by using specialized resin-based systems.

Durability

The windows made of wood in many old structures were designed to last for a long time. They do require some maintenance to keep them looking good. The most frequently-asked maintenance tasks include repairs to sash cords, re-tightening sash pulleys, and painting. There is also a rising demand for upgrading timber windows to increase energy efficiency. This may mean replacing old glass units, repairing the window rebates that are in place or putting up new cills for improved air sealing.

One of the major issues with traditional windows is the damage caused by the corrosion of the paintwork. This is especially important when it comes to sash windows, as the gaps between sashes may be very large. In these situations water can get into the paint film and cause rotting of the putty as well as underlying wood. The rotting can be exacerbated due to weather conditions that are poor. To stop this from happening windows from becoming rotten, they must be regularly painted with an exterior wood paint that is suitable.

The areas that are damaged should be repaired with a resin-based product. This will ensure that the best possible amount of the original fabric remains. It is essential to limit the number of holes that are created into the frame to allow cable entry, because they could let in moisture and cause decay.

The structural movement of the wall can cause distortions in the frame and sash. This could result in the sash not fitting properly or sticking or jamming into the opening, and damaged glazing. Often this can be corrected through the installation of new sash boxes made from slow grown deal (pine) or oak. The cill must be made from a sturdy hardwood, such as oak, to prevent the movement of new and older work.

There are now several companies that make Boston pattern wooden sash to fit most existing openings. They are available in a range of sizes and finishes that meet the requirements of the modern homeowner. These sash are combined with quadruple draft strips and a more efficient thermal insulation, could make a significant difference to the energy-efficiency of a home.

Aesthetics

Many old wooden windows have an excellent aesthetic value because they typically show, in a particular way the materials and technologies and architectural style of the time from which they originate. They could also have a significant historic value in their individual cases. This is especially true of early unglazed window openings in timber-framed buildings, where the great majority were merely a series of openings in the structural frame sub-divided horizontally into mullions and vertical iron or wood bars to keep out invaders.

Traditional window joinery made of timber can be a stunning aspect of a building, and it is important to keep it looking good. It is crucial that any decay resulting from water penetration is immediately stopped once it is discovered. This is best accomplished by applying a thorough coat of paint, particularly in areas that have already suffered damage or degradation. It is best to use paints that are designed to be used in a system (primer undercoat and finish) and to follow the manufacturer's guidelines for preparation and number of coats at each stage.

The fungus responsible for wet rot can spread quickly in old timber windows. To prevent this, get rid of any rotten or damaged parts as promptly as you are able to. Replace rotting wood with slow-grown deal (pine) and, when possible, the exact type of wood that is being removed to prevent the possibility of differential movement.

In the late the 17th and early the medieval periods, glass became more affordable and abundant, so that the glazed openings in timber-framed buildings gradually became sophisticated with wooden tracery moulded mullions, moulded mullions, and deep protruding cills. The glazing was increasingly placed within frames with rebates and then pinned with 'cambridge double glazing sprigs' rather than into lead cames. This method of glazing is not only less susceptible to leaks, but also allows for more expansive and clearer sheets of glass to be used in the windows than would be possible without the need for leaded lights.

Energy efficiency

Traditional timber windows offer excellent energy efficiency due to their thickness and multi-layer construction, as well as attentive attention to detail. The large glass areas, the deep projecting cills and large glazing areas help to reduce air infiltration. The windows can be modified to increase their energy efficiency with draught-proofing and secondary double glazing repairs. However it is essential to remember that such measures should be viewed in relation to the overall appearance and integrity of the original window.

It makes sense to fix or upgrade windows that are older rather than replacing them, particularly when improvement in thermal efficiency can be achieved through simple fixes. Older windows typically have an historic value that illustrates a variety of technical development and changes in architectural style. Most people assume that these windows will need to be replaced in the near future. However, many of them will last for 150, 200 or even 250 years if you take care of maintenance.

It is crucial to understand that decay issues associated in traditional timber windows are preventable by quick and thorough repairs. Additionally, it is essential to recognize damp penetration issues and fix them promptly to prevent serious damage. The early deterioration of paint is a concern because it allows moisture to get into the wood, leading to wet rot. The damage is usually not noticed until the paintwork becomes cracking or wavy, but can cause significant structural damage and lead to further decay.

A paint of good quality will block moisture penetration. To avoid condensation and mould it is crucial to keep the paintwork as clean as possible. The use of modern synthetic paints can pose a problem since they are typically designed to be water-resistant and this may cause the growth of mildew within the window frame.

The majority of windows from the past were constructed from sapwood-rich timber. The timbers will deteriorate rapidly if exposed to wet weather conditions, but they can be protected with a thorough preservative treatment before they are used. It is crucial to select the right kind of wood for the location and climate, as these factors can affect the durability of the joinery. Local window manufacturers provide various types of timber sash which can be customized to fit historic openings. They are available in the standard Boston pattern or in custom sizes to fit historical buildings.

Maintenance

Regular inspections as well as careful redecoration and timely repairs can prolong the life of timber windows. The primary reason for decay is the infiltration of moisture through deteriorated paint and putty. This can be prevented by careful painting and the use of high-quality wood preservative.

It is important that repairs to old sash or casement windows are well executed and completed with the minimum disturbance. upvc Doors repairs can be made to many traditional timber window designs without having to remove the frame. This should be done whenever possible. Remove peeling or loose paint and then lightly sand the surface to improve the "key" of the surface. This will enable the new coating to adhere better. It is essential to not remove old paint layers, as they may have historical significance.

When a section of wood is rotting the best option is to remove it and replace it with timber inserts that are shaped to match existing profiles. The wood that is being inserted should be treated with wood preservative, and the junction between the timber cill and the sub-cill of the masonry should be sealed.

It is tempting to replace traditional windows with PVC u, particularly if the installer offers an installation that includes both removal and replacement in a single day. It is, however, essential that the person installing replacement windows has a full knowledge of the structure and history of traditional timber frames. This will allow them to make the right suggestions for improvements to energy efficiency and other technical upgrades that do not alter the character of a historic building. The window installers who provide replacement windows must be registered with a Competent Persons Scheme like FENSA. This will ensure that replacement windows are approved by the Building Regulations as a suitable alternative. A skilled carpenter can put in PVC-u windows that conform to original building's character. This is particularly applicable when windows are located within listed buildings or conservation areas.
