Maintaining Timber Windows

A well-maintained wooden sliding doors cambridge window is an essential part of a historic building. It reflects in different degrees, the materials and technologies of the time in which it was constructed, as well as the craftsmanship and architectural taste.

When repairs are feasible to existing windows are required, they should be carried out in situ. Repair systems made of resin can be used to fix the most damaged areas of decay without removing the whole upvc window and door repairs.

Durability

Timber windows were made to last for hundreds of years. They require regular maintenance to ensure they look good. Maintenance tasks include sash cord repairs as well as tightening the pulleys for sash and painting. The demand for enhancing timber windows in order to increase efficiency in energy use is also growing. This could include replacing old glazing units, repairing existing window repairs near me rebates or installing new cills to increase the air seal.

One of the major issues with traditional windows is damage caused by the corrosion of the paintwork. This is particularly important when windows made of sash are involved because the gaps between the sashes can be quite wide. In these instances, water can penetrate paint film and cause rotting of the wood or putty beneath. Poor weather conditions can exacerbate the rotting. To stop this from happening, windows must be painted regularly with an exterior wood paint.

In addition to repainting, areas that have corroded should be repaired with an adhesive-based repair product. This will ensure the maximum amount of original fabric is preserved. It is essential to limit the number of holes that are made into the frame in order to allow cable access, since they can let in moisture and cause decay.

Another major issue with older windows is structural movement in the wall that can cause deformation of the frame and the sash. This could result in the sash not fitting properly and jamming or sticking to the opening and broken glazing. Most often, this is corrected by the fitting of new sash boxes that have been constructed from slow-growing deal (pine) or oak. The cill must be made of a durable hardwood, like oak, to avoid the movement of new and old work.

There are now several companies that produce Boston pattern wooden sash that fit most existing openings. These sash come in various sizes and finishes that suit the needs of modern-day homeowners. The new sash, combined with quadruple draft strips and improved thermal insulation can significantly improve the energy-efficiency of a home.

Aesthetics

Many old timber frames have a great aesthetic appeal, as they reflect, in some form, the quality of the wood technology, the construction process, and the architectural taste from the time period they were made. They could have significant historical value as a set. This is especially true of early windows that were not glazed in timber-framed buildings, which were merely a series of openings within the structural frame sub-divided horizontally into mullions and wood or iron bars to keep out invaders.

It is important to maintain the appearance of traditional timber window sill Repair joinery. As soon as you notice any signs of decay caused by the penetration of moisture, it is important to stop it. This is best accomplished by applying a thorough coat of paint, particularly in areas that have already suffered damage or deterioration. It is advisable to use paints that are specifically designed to be used part of the system (primer undercoat, finish) and to follow the manufacturer's recommendations in relation to preparation and the number of coats needed at each stage.

The fungus that causes wet rot is able to spread quickly in old timber windows. To prevent this from happening, take out any damaged or rotten components as quickly as you can. The replacement of wood that is rotting should be carefully undertaken by using a slow-growing deal (pine) and, wherever feasible it is the same species as that which is being removed to avoid shifting between the new and old timbers.

In the late medieval and 17th century periods glass became cheaper 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. The glazing was increasingly set within rebated frames and pinned in by 'glazing sprigs' rather than being inserted into lead cames. This method of glazing is not only less prone to leaking but it also allows more expansive clearer, more transparent sheets of glass to be used in the windows than would have been possible without the need for lead lights.

Energy efficiency

The traditional timber windows are energy efficient because of their thickness and multilayer construction, as well as their focus on particulars. The large glass surfaces, the deep projection cills and wide glazing areas reduce air infiltration. The windows can be made to increase their energy efficiency by draught-proofing and secondary glazing. It is important to remember that these measures need to be taken into consideration when it comes to the overall integrity and appearance of the original windows.

It is sensible to fix or upgrade historic windows rather than replace them, especially when the improvement in energy efficiency can be made through simple repairs. Historic windows are often of historical significance, since they show a range in technological advancement and changes in architectural style. The pressures to replace these windows are typically based on the assumption that windows of the past will require replacement in the near future, but they are capable of serving for 150, 200 or even 250 years, if properly maintained.

It is essential to realize that decay issues in traditional timber windows are easily prevented with timely and thorough repairs. Additionally it is crucial to recognize damp penetration issues and to remedy them quickly to avoid major damage. The early deterioration of paint is a major problem as it allows moisture to penetrate the wood and cause wet rot. It is not uncommon for this issue to go undetected until the paintwork begins to crack or become wavier. However, it can cause structural damage and further decay.

A good quality paint will prevent this moisture from entering. It is also necessary to keep the paintwork spotless to avoid condensation and the growth of mould. Modern synthetic paints are problematic because they are water-resistant and can cause mildew to grow in the window frame.

Most older windows were made of sapwood-rich timber. These timbers can deteriorate quickly when exposed to rain, however they can be protected by an extensive preservation treatment prior to use. It is important to choose the right kind of wood for your location and climate, as these factors can affect the longevity of the joinery. Local window manufacturers make various types of timber sash that can be customized to fit specific historic openings. They are available in the standard Boston pattern or in custom sizes that can be adapted to the architectural style of historic structures.

Maintenance

The life of timber windows can be extended significantly through regular inspections carefully redecoration, and timely repair. The main cause of decay is moisture penetration through deteriorated paint or putty. This can be prevented by careful painting and using high-quality wood preservative.

Repairs to old sash windows and casement window frames must be done with care and minimal disruption. Repairs can be made to several traditional designs of timber windows without having to remove the frame. This should be done whenever possible. Remove any peeling or loose paint and lightly sand the area to improve the 'key" of the surface. This will enable the new coating to stick better. Be careful to avoid stripping paint layers that might have historical significance, and where these are present, it is recommended that a paint analysis be conducted.

If a piece of wood has rotted the best way to deal with it is to remove it and replace it with timber inserts shaped to match the existing profiles. The timber that is inserted should be treated with wood preservative and the junction between masonry sub-cill and timber cill should be sealed.

It's tempting to replace traditional windows with PVC u, particularly if the installer offers an installation that includes both removal and replacement within a single day. It is, however, crucial that the person who installs cambridge replacement windows windows has a complete knowledge of the construction and history of traditional timber frames. This will enable them to make the right suggestions for improvements to energy efficiency and other technical upgrades that will not harm the historic character of a building. Window replacements should be registered with a Competent Persons Scheme like FENSA. This will ensure that the replacements are approved as a suitable solution under Building Regulations. A skilled carpenter is able to install PVC-u windows that conform to the original character of the building. This is particularly true where windows are installed in listed buildings and conservation areas.
