Maintaining Timber Windows

A well-maintained wooden window is a crucial element of a building that is historic. It demonstrates in various degrees the materials and technologies design, craftsmanship and aesthetics of the time period from which it dates.

Whenever possible repairs to existing windows are required, they should be done in-situ. Repairing the most deteriorated areas of decay can be done by using specialized resin-based systems.

Durability

The timber windows cambridge in many historic buildings were made to last for hundreds of years. They do require maintenance to ensure they look good. Maintenance tasks include repairs to sash cables and retightening pulleys on sash, and painting. The demand for enhancing timber windows in order to increase energy efficiency is also growing. This could include replacing old glazing units, repairing existing window rebates or installing new cills for improved air seal.

One of the main issues with traditional windows is damage caused by corrosion of the paintwork. This is particularly important in the case of sash windows because the gaps between sashes can often be extremely large. In these cases water can enter the paint film and cause rotting of the putty or wood beneath. Poor weather conditions can exacerbate the rotting. To stop this from happening, windows should be painted regularly with an exterior wood paint.

The areas that are damaged should be repaired with a resin-based product. This will ensure that the maximum amount of original fabric retained. It is also important to minimise the number of holes drilled into the frame to allow cable entry as these can admit water and lead to decay.

Another issue with older windows is structural movement in the wall, which can lead to deformation of the frame and sash. This can lead to sash no longer fitting correctly, sticking or jamming in the opening and broken double glazing repairs. This is often corrected by fitting new sash frames made of slow-grown deal (pine), or oak. The cill should be constructed from durable hardwood such as oak to avoid any movement between the existing and new work.

To help reduce this problem There are a number of companies who produce Boston pattern wooden sash that can be fitted into most openings. These sash are available in a variety of sizes and finishes that meet the needs of the modern homeowner. These new sash, when coupled with quadruple draft strips and improved thermal insulation can make a huge difference to the efficiency of a home's energy use.

Aesthetics

Many old wooden windows have an excellent aesthetic value as they often demonstrate, in a way the materials and techniques and architectural taste of the time in when they were built. They could also have a significant historical significance in their in their own right. This is particularly true of early windows that were not double glazed door seal repairs in timber-framed buildings, which were merely a series of openings within the frame that were subdivided horizontally into mullions and iron or wood bars to deter invaders.

It is important to maintain the appearance of traditional timber Basement Window repair joinery. As soon as you notice any decay caused by the penetration of moisture it is crucial to stop it. It is recommended to do this with thorough painting, especially if there has been damage or deterioration. It is advisable to use paints that are designed to be used as part of the system (primer undercoat, finish) and to follow the manufacturer's recommendations regarding preparation and number of coats needed at each stage.

The fungus responsible for wet rot can spread quickly in old windows made of wood. To prevent this from happening, get rid of any rotten or damaged parts as soon as you can. The replacement of rotting wood should be done with care and using slow grown deal (pine) and, whenever feasible, the same species as that which is being removed to prevent shifting between the new section and the existing timbers.

In the late medieval and 17th century periods glass became less expensive and more plentiful so that glazed openings in timber-framed buildings gradually became more elegant with wooden windows cambridge tracery, moulded mullions and deep projection cills. In recent times, glass was pinned into frames that were rebated with glazing sprigs rather than lead cames. This method of glazing not only makes the windows less likely to leak and also allows wider sheets of clearer glass to be used than would have been feasible without the use of led lights.

Energy efficiency

Traditional timber windows offer an excellent energy performance due to their thickness and multi-layer construction, as well as meticulous attention to detail. They also have large glass areas as well as deep projecting cills that minimise air infiltration. The windows can be made to improve their energy efficiency through draughtproofing and secondary glazing. It is essential to keep in mind that these measures need to be considered when it comes to the overall appearance and integrity of the original windows.

It is logical to repair or upgrade existing windows that are older rather than replacing them, especially when the improvements in thermal efficiency can be made through simple repairs. The windows of the past often have historical significance that shows a variety of technical development and changes in architectural tastes. The pressures to replace these windows are usually based on the assumption that old windows will need replacement in the near future, but most are still capable of serving for 150, 200 and even 250 years if properly maintained.

It is crucial to understand that decay issues associated with traditional timber windows can be easily prevented with prompt and thorough repairs. Additionally it is crucial to spot damp penetration issues and fix them promptly to avoid major damage. The early deterioration of paint is a concern because it allows moisture to penetrate into the wood, which can cause wet rot. It is not uncommon for this type of damage to go unnoticed until paintwork begins to crack or become curly. However, it could cause structural damage and then further decay.

A high-quality paint will prevent this moisture penetration. To prevent condensation and mould it is crucial to keep the paintwork as clean as you can. The use of modern synthetic paints can pose a problem since they are typically designed to be water-resistant and this may result in the formation of mildew in the window repairs cambridge frame.

The majority of windows from the past were constructed from sapwood-rich wood. The timbers will deteriorate quickly when exposed to wet weather, however they can be preserved with an extensive preservative treatment prior to when they are used. It is also important to ensure that the kind of wood used is suitable to the site and climate conditions, as these factors will influence the durability of the joinery. Local window manufacturers provide an array of sash made from timber that can be adapted to fit historical openings. They can be made in the standard Boston pattern or in custom sizes to suit historical structures.

Maintenance

Regular inspections as well as careful redecoration and quick repairs can prolong the life of timber windows. The most common reason for decay is moisture infiltration through deteriorated paint and putty. This can be avoided with thorough painting and the use of high-quality wood preservative.

It is important that repairs to old sash and casement windows are done correctly and done with the minimum disturbance. Many of the traditional designs for timber windows are repairable without removing the frame, and this option should be used whenever it is possible. Remove loose or peeling paint and lightly sand the surface to improve the 'key" of the surface. This will enable the new coating to adhere better. It is important to avoid stripping paint layers that might have historical significance, and where these are present it is recommended that a study of the paint be conducted.

If a portion of wood is decayed, the best solution 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 a wood preserver and the connection between the timber cill and sub-cill of the masonry should be sealed.

It is tempting to replace traditional windows with PVC u, especially when the installer offers an installation that includes both removal and replacement within a single day. However, it is crucial that the person who installs replacement windows has a full knowledge of the structure and history of traditional wooden frames. This will allow them to make appropriate recommendations for energy efficiency improvements as well as other technological improvements that don't alter the appearance of an historic building. Those who provide replacement windows must be registered under a Competent Persons Scheme like as FENSA. This will ensure the replacements are deemed to be approved by the Building Regulations as a suitable option. A skilled carpenter can put in PVC-u windows that are suited to the original character of the building. This is especially true when windows are situated in listed buildings and conservation areas.
