Maintaining Timber Windows

A well-maintained wooden window is an essential part of a historic building. It demonstrates in various degrees the different materials and technologies design, craftsmanship and aesthetics of the time from which it originates.

If possible, repairs should be made in-situ. Repairing the most severe areas of decay can be done by using specialized resin-based systems.

Durability

Timber windows were built to last for hundreds of years. They do require maintenance to keep them looking good. Maintenance tasks include sash cord repairs, retightening of sash pulleys and painting. There is also a growing demand to upgrade the timber windows to increase energy efficiency. This may include replacing old glazing units, fixing the window rebates that are in place or installing new cills to improve air seal.

The corrosion of paintwork is a major problem with traditional windows. This is especially true in the case of sash windows as the gaps between sashes can often be quite large. In these cases water can get into paint film and cause rotting of the putty or wood beneath. The rotting may be further aggravated due to weather conditions that are poor. To prevent this windows from becoming rotten, they must be painted regularly with a suitable exterior wood paint.

In addition to repainting, areas that have corroded should be repaired with a resin-based repair product. This will ensure that the maximum amount of original fabric is preserved. It is also essential to limit the number of holes that are drilled into the frame for cable entry, as they could admit water and lead to decay.

The wall's structural movement could also cause deformations in the frame and sash. This could result in the sash fitting incorrectly jamming, sticking or sagging in the opening, and even broken glass. This can often be fixed by the fitting of new sash boxes that have been constructed from slow-growing deal (pine) or oak. The cill needs to be constructed of a durable hardwood, such as oak, to prevent shifting between the new and old work.

To alleviate this issue There are several companies that produce Boston pattern sash made of wood that can be fitted into most openings. The sash is available in a range of sizes and finishes to suit the needs of the modern homeowner. These sash are combined with quadruple draft strip and improved thermal insulation can make a significant difference to the energy-efficiency of a home.

Aesthetics

Many old timber windows have a high aesthetic value as they often illustrate, in some way, the materials and technology and architectural taste of the time in which they originate. They could also have a significant historical significance in their in their own right. This is especially true of early windows that were not glazed in timber-framed buildings, in which the majority were simply a series of openings within structural frames subdivided horizontally by mullions and vertical iron or wood bars to keep out intrusions.

It is important to maintain the appearance of traditional timber upvc window lock repair joinery. As soon as you notice any signs of decay due to moisture penetration it is essential to stop it. It is recommended to do this by thorough painting, particularly if there is damage or degradation. It is recommended to use paints that are specifically designed to be used as part of a system (primer as well as undercoat, finish and primer) and follow the manufacturer's instructions regarding preparation and number of coats required at each stage.

Wet rot is a common problem for old timber windows. The best method to stop it from becoming a problem is to take out sections that are damaged or rotten as soon as possible to prevent the spread of the fungus that causes it. Replace the wood that is rotting with slow-growing deal (pine) and, when possible, the exact type of timber as the one that is being removed, to prevent the possibility of differential movement.

Glass became cheaper and more abundant during the late medieval period and into the 17th century. This led to the openings for double glazed door repairs windows on timber-framed houses were more elaborate, with moulded mullions and traceries, made of wood and deep cills projecting into the air. Increasingly, the glazing was laid within rebated frames and then pinned with 'glazing sprigs', rather than being inserted into 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 employed than would be possible otherwise without the use of led lights.

Energy efficiency

Traditional timber windows offer excellent energy efficiency due to their thickness and multi-layer construction. They also pay careful attention to detailing. They also have large glass areas and upvc window And Door Repairs deep projecting cills that minimise air infiltration. The windows can be modified to increase their energy efficiency through draughtproofing and secondary glazing. However it is crucial to keep in mind that any such measures should be evaluated in the context of the overall integrity and appearance of the original window.

Therefore, keeping existing historic windows that require repair instead of replacing them is sensible particularly when thermal enhancements can be achieved cost-effectively through simple repairs and improvements. The windows that are historic have a lot of historical value, as they demonstrate a variety in technological advancement and changes in the architectural style. The pressures to replace these windows are generally based on the assumption that windows that are old will need to be replaced in the near future, however most are still capable of providing service for 150, 200 or even 250 years if properly maintained.

It is important to recognise that the decay issues that are that are typical of windows made of timber can be avoided through regular maintenance and prompt repairs. Additionally it is vital to identify damp penetration problems and to remedy them quickly to avoid serious damage. Early paint deterioration could be a problem as it allows moisture to penetrate into the wood, which can cause wet rot. It is not uncommon for this issue to go undetected until the paintwork begins to crack or become curly. However, it can cause structural damage and further decay.

A paint of good quality will block moisture penetration. To prevent mould and condensation, it is important to keep the paintwork as clean as it can be. Modern synthetic paints could be a problem, as they are often made to be water-resistant and this can result in the formation of mildew within the window supplier cambridge frame.

The majority of older windows were manufactured from timber containing the majority of sapwood. These timbers can deteriorate very quickly when exposed to wet weather, but can be protected by a thorough treatment of preservative before they are put to use. It is essential to select the right kind of wood for the site and the climate, since these factors can affect the longevity of the joinery. Local window manufacturers make a range of sash made of timber that can be adapted to fit specific openings from the past. They can be produced in the standard Boston pattern or in custom sizes to fit the architectural style of historic buildings.

Maintenance

Regular inspections carefully redecorated, as well as timely Emergency Upvc Door Repairs can prolong the life of timber windows. The primary cause of wood decay is moisture leaking through deteriorated paint or putty. This can be prevented by careful painting and the use of high-quality wood preservative.

It is crucial that repairs to old sash and casement windows are done correctly, and carried out with minimal disruption. It is possible to fix the majority of traditional wooden windows cambridge window designs without removing the frame. This should be done whenever possible. Remove any peeling or loose paint and then lightly sand the surface to improve the 'key" of the surface. This will allow the new coating to stick better. It is important to avoid removing old paint layers, which could have historical significance.

Where a section of timber has become rotten the best option is to remove the rotted material and replace it with spliced-in inserts that are shaped to fit the existing profiles. The wood that is being inserted should be treated with a wood preservative, and the junction between the timber cill and sub-cill of the masonry should be sealed.

Replacement of windows made of traditional PVC-u can be an attractive option, especially when the installer offers an "all-in-one" installation that takes care of removal and replacement within one day. It is essential that installers of replacement windows have a thorough understanding of the history and construction of traditional timber frames. This will allow them to make the right suggestions for energy efficiency improvements and other technical upgrades that won't harm the character of a historic building. Those providing replacement windows should be registered with a Competent Persons Scheme such as FENSA. This will ensure that the replacements are deemed acceptable in accordance with Building Regulations as a suitable option. It is certainly possible for an experienced and skilled carpenter to install PVC-U windows that match the character of the original building. This is especially true when the windows are located in listed buildings or conservation areas.
