Cambridge Window Tips From The Top In The Business

Maintaining Timber Windows

A well-maintained window made of timber is a significant element of the historical structure of a building. It reflects in different degrees, the materials and technologies of the time it was constructed, as well as the architectural style and craftsmanship.

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

Durability

Timber windows were built to last for centuries. They do require maintenance to keep them looking good. The most common maintenance tasks include repairs to sash cords as well as tightening sash pulleys and painting. The demand for enhancing windows made of timber to improve efficiency in energy use is also growing. This could mean replacing old glass units, fixing existing window rebates or putting up new cills for improved air sealing.

The deterioration of paintwork is a major issue with traditional windows. This is particularly important when windows with sash are involved since the gaps between sashes can be quite large. In these cases water can enter the paint film and cause rotting of the putty or wood beneath. The rotting process can be made worse due to weather conditions that are poor. To prevent 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 that the maximum possible amount of the original fabric is preserved. It is also essential to minimise the number of holes drilled into the frame to allow cable entry since these could allow water in and cause decay.

Another issue with older windows is structural movement in the wall which can lead to deformation of the frame and sash. This can result in the sash fitting incorrectly, jamming or sticking in the opening, or breaking glass. This can often be fixed by fitting new sash boxes that have been constructed from slow-growing deal (pine) or oak. The cill should be constructed from durable hardwood such as oak to avoid any movement between the old and new work.

To reduce the risk There are several companies that manufacture Boston pattern sash made of wood that will fit into the majority of existing openings. The sash is available in various sizes and finishes that meet the requirements of modern-day homeowners. These new sash, when combined with quadruple draft strips and a more efficient thermal insulation, could significantly improve the efficiency of your home's energy usage.

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 built. They could also have a significant historical significance in their in their own right. This is particularly true of early unglazed windows in timber-framed buildings, in which the majority were series of openings within structural frames subdivided horizontally by mullions and vertical iron or wood bars in order to keep out invaders.

Traditional timber window joinery can be a highly decorative element of a structure and it is important to keep it looking good. As soon as you see any decay caused by water penetration it is essential to stop it. This is best accomplished by painting thoroughly, especially in areas in which there is already damage or degradation. It is best to choose paints that are intended to be used in a system (primer undercoat and finish) and to adhere to the manufacturer's recommendations for preparation and number of coats at each stage.

The fungus responsible for wet rot can spread quickly in old timber windows. To stop this from happening, take out any damaged or rotten components as promptly as you are able to. Replace the wood that is rotting with slow-growing deal (pine) and, if possible, the same kind of timber as the one that is being removed, to prevent differential movement.

Glass became less expensive and more abundant during the late medieval period and into the 17th century. This led to double glazed door seal repairs openings on timber-framed houses were more elaborate, with moulded mullions, tracery made of wood and deep projecting cills. In the past, more often, the glass was placed within frames with rebates and secured with 'glazing sprigs' rather than into lead cames. This method of Double glazing seal repairs not only makes the windows less likely to leak, but also allows for larger sheets of glass to be employed than would be possible without the use of leaded lights.

Energy efficiency

Traditional timber windows offer an excellent energy performance due to their thickness, multi-layer construction and very attentive attention to detail. They also feature large glass areas and deep projection cills which reduce air infiltration. Windows can be designed to increase 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.

Therefore, keeping old windows that are in need of repair instead of replacing them is sensible particularly when thermal enhancements can be made inexpensively with simple repairs and improvements. The windows that are historic have a lot of historical value, as they show a range in technological advancements and changes to architectural taste. The pressures to replace such windows are generally 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 they are properly maintained.

It is essential to understand that the decay issues that are typical of windows made of timber can be avoided by thorough maintenance and prompt repairs. Additionally it is vital to spot damp penetration issues and to remedy them quickly to avoid major damage. Early deterioration of paint is a major issue, because it allows moisture to penetrate the wood and cause wet rot. This type of damage is typically not apparent until the paintwork is cracking or wavy, but can cause significant structural damage and lead to further decay.

A quality paint will stop moisture from entering the paint. It is also important to keep the paintwork spotless to avoid condensation and the growth of mould. The use of modern synthetic paints can pose a problem, as they are often made to be water-resistant and this can cause the growth of mildew inside the window hinges leeds frame.

Most older windows were made from sapwood-rich wood. The timbers will deteriorate rapidly if exposed to rain, however they can be protected by a thorough preservation process prior to use. It is also crucial to ensure that the kind of wood used is suited to the location and climate conditions, since these factors will influence the durability of the joinery. Local window manufacturers make various types of timber sash that can be tailored to fit specific historic openings. They can be made in the standard Boston pattern or in custom sizes that can be adapted to the architectural style of historic buildings.

Maintenance

Regular inspection, careful redecoration, and quick repairs can prolong the lifespan of windows made of timber. The most common reason for the decay is moisture infiltration through deteriorated paint and putty. This can be prevented by thorough painting and using high-quality wood preservative.

Repairs to old sash windows as well as casement window doctor frames should be done with care and with the least amount of disruption. It is possible to fix several traditional designs of timber windows without removing the frame. This is a must whenever it is possible. Peeling or loose paint should be removed with care and sanded lightly to improve the key of the surface and facilitate a better adhesion of the new coating. It is essential to avoid removing old paint layers, as they may have historical significance.

When a section of wood is decayed, the best solution is to remove it and replace it with timber inserts designed to match existing profiles. The timber inserts should be treated with wood preservative, and the joint between masonry sub-cills and timber cill should be sealed.

Replacement of traditional windows with PVC-u may be an appealing option, particularly when the installer offers an "all-in-one" installation that takes care of removal and replacement within one day. It is crucial that the person who installs replacement windows has a full knowledge of the construction and history of traditional timber frames. This will allow them to make the appropriate recommendations for energy efficiency improvements and other technical upgrades that do not alter the historic character of a building. The window installers who provide replacement windows must be registered with a Competent Persons Scheme like FENSA. This will ensure that the replacements are approved as a suitable option under Building Regulations. A skilled carpenter can install PVC-u windows that conform to the original character of the building. This is particularly applicable when windows are situated within conservation areas or listed buildings.
