What's The Reason? Cambridge Window Is Everywhere This Year
Maintaining Timber Windows

A well-maintained wooden window is a crucial element of a building that is historic. It reflects in different degree the technology and materials of the time period it was constructed, the design and craftsmanship.

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

Durability

The windows made of timber in many old buildings were built to last for a long time. However, they need to be maintained to ensure they look good and operating correctly. Maintenance tasks include repairs to sash cables, retightening of sash pulleys and painting. The demand for upgrading timber windows in order to improve energy efficiency is also growing. This could mean replacing old glass units, repairing the window rebates that are in place or putting in new cills to allow for better air sealing.

A key problem with traditional windows is the damage caused by corrosion of the paintwork. This is especially true when sash windows are concerned, as the gaps between sashes can often be very large. In these instances, water can penetrate paint film and cause rotting of the wood or putty underneath. The rotting may be further aggravated by weather conditions that are not ideal. To stop this from happening, windows should be painted regularly with an exterior wood paint.

The areas that are damaged should be repaired using a resin-based product. This will ensure that the greatest amount of original fabric is preserved. It is also necessary to reduce the number of holes that are drilled into the frame for cable entry since these could admit water and lead to decay.

Another major issue with older windows is structural movement in the wall, which can lead to deformation of the frame and sash. This could result in the sash not fitting properly and jamming or sticking to the opening and cracked glazing. Often this can be corrected through the installation of new sash boxes that have been made from slow grown deal (pine) or oak. The cill should be made from a sturdy hardwood such as oak to avoid differential movement between the new and existing work.

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

Aesthetics

Many old timber windows have a great aesthetic value as they often demonstrate, in a way the materials and techniques and architectural taste of the time in which they date. They may have significant historical value on their own. This is especially true of early windows that were not glazed in timber-framed buildings, where the great majority were simply a series of openings in the frame, which were divided horizontally into mullions and wood or iron bars to keep out invaders.

It is important to maintain the appearance of traditional wooden window joinery. As soon as you see any signs of decay due to moisture penetration, it is important to stop it. It is recommended to do this through thorough painting, especially where there is damage or degradation. It is recommended to choose paints that are intended 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 timber. To prevent this from happening, get rid of any rotten or damaged parts as quickly as you can. Replace rotting wood with slow-grown deal (pine), and if possible, the same kind of timber that is being removed, to avoid any differential movement.

Glass became less expensive and more abundant in the late medieval era and into the 17th century. In the process, the openings for glazed windows on timber-framed houses were more elaborate, with moulded mullions and traceries, made of wood and deep cills projecting into the air. In recent times, glass was fixed into frames that were rebated with glazing sprigs, not lead cames. This method of glazing is not only less susceptible to leaks, but it also allows more expansive and clearer sheets of glass to be used in the windows than would have been possible without the need for lead lights.

Energy efficiency

Traditional timber windows are energy efficient because of their thickness and multilayer construction, as well as their focus on detail. They also have large glass areas and deep projection cills which reduce air infiltration. Windows can be designed to increase their energy efficiency with draught-proofing and secondary glazing. It is crucial to keep in mind that these measures need to be taken into consideration in relation to the overall appearance and integrity of the original windows.

Therefore, keeping old windows that are in need of repair instead of replacing them makes sense especially when their thermal enhancements can be made economically through simple repairs and upgrades. The windows of the past often have a historical value that shows a variety of technological advances and changes in architectural taste. Most people think that these windows will need to be replaced in the near future. However, window repair near me will last for 150, 200 or even 250 years with proper maintenance.

It is essential to realize that decay issues associated with traditional timber windows are easily prevented with prompt and thorough repairs. It is also essential to spot damp issues and correct them swiftly in order to avoid major damage. Paint deterioration that occurs early can be a problem because it allows moisture to get into the wood, causing wet rot. It is not uncommon for this damage to go unnoticed until the paintwork begins to crack or become curly. However, it could cause structural damage and lead to further decay.

A good paint will prevent moisture penetration. It is also important to keep the paintwork in good condition to avoid condensation and mould growth. Modern synthetic paints can pose a problem since they are typically formulated to be water-resistant, and this can result in the formation of mildew in the window frame.

The majority of windows from the past were manufactured from timber containing a high proportion of sapwood. These timbers are susceptible to deterioration quickly when exposed to moist weather conditions, but they can be protected with a thorough preservative treatment before they are used. It is important to choose the right kind of wood for your location and climate, as these factors will affect the durability of the joinery. Local window manufacturers have various types of timber sash which can be customized to fit historic openings. They can be produced in the standard Boston pattern or in custom sizes to suit historical buildings.

Maintenance

Regular inspections carefully redecorated, as well as timely repairs can prolong the life of wooden windows. The main cause of decay is moisture leaking through the deteriorated paint and putty. This can be prevented by careful painting and using an excellent wood preservative.

Repairs to old sash windows as well as window frames made of casement must be done with care and with minimal disruption. It is possible to repair many traditional timber window designs without having to remove the frame. This is a must whenever it is possible. Remove peeling or loose paint and lightly sand the surface to improve the "key" of the surface. This will allow the new coating to adhere better. It is important to avoid stripping old paint layers that might have historical significance, and where these are present it is recommended that a study of the paint be conducted.


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

It's tempting to replace traditional windows with PVC u, particularly if the installer offers an all-in-one installation that includes both removal and replacement in one day. It is essential that installers of replacement windows are aware of the history and construction of traditional timber frames. This will enable them to make the appropriate suggestions for improvements to energy efficiency and other technical upgrades that will not harm the historic character of a building. Those who provide replacement windows should be registered under a Competent Persons Scheme like as FENSA. This will ensure the replacements are deemed to be approved in accordance with Building Regulations as a suitable option. It is certainly possible for a skilled and experienced carpenter to install PVC-U windows that fit the the building originally. This is especially true where windows are installed in listed buildings and conservation areas.
