Maintaining Timber Windows

A well-maintained wooden Window Lock Repairs is a crucial component of a historical building. It reflects, in various levels, the materials and technologies of the time period it was constructed, as well as the craftsmanship and architectural taste.

If repairs are possible to existing windows should be carried out in-situ. Repair systems made of resin can be used to fix the most deteriorated areas without removing the whole window.

Durability

The timber windows in many historical structures were designed to last for hundreds of years. They do require maintenance to keep them looking great. Maintenance tasks include repairs to sash cables, retightening of sash pulleys and painting. The demand for upgrading timber windows in order to improve efficiency in energy use is also growing. This could include replacing old glazing units, repairing the window rebates that are in place or installing new cills for improved air seal.

The deterioration of paintwork is a major problem with traditional windows. This is especially important in the case of sash windows as the gaps between sashes can often be very large. In these situations water can get into paint film and cause rotting of the wood or putty underneath. The rotting may be further aggravated due to weather conditions that are poor. To prevent this windows, they should be regularly painted with a suitable exterior wood paint.

In addition to repainting, areas that have corroded should be repaired with the help of a resin-based repair solution. This will ensure that the greatest amount of the original fabric is retained. It is also essential to minimise the number of holes that are drilled into the frame to allow cable entry since these could admit water and lead to decay.

Another issue with older windows is the structural movement within the wall which could cause deformation of the frame and the sash. This could result in sash no longer fitting correctly or sticking or jamming into the opening, and damaged glazing. This can often be fixed by the fitting of new sash boxes made from slow grown deal (pine) or oak. The cill should be made from a sturdy hardwood such as oak to avoid any movement between the new and existing work.

There are now several companies that produce Boston pattern wooden sash to fit in with the majority of openings. These sash come in a variety of sizes and finishes to fit the needs of modern homeowners. In conjunction with quadruple draught strip and improved thermal insulation, these new sash can make significant improvements to the energy efficiency of a home.

Aesthetics

Many old timber windows have a high aesthetic value since they usually illustrate, in some way, the materials and technology and architectural style of the period from when they were built. They could have significant historical significance as a set. This is particularly true for early unglazed windows in timber-framed buildings, where the majority of them were series of openings in frames of structural construction, which were divided horizontally by mullions and vertical wood or iron bars to keep out intruders.

Traditional window joinery made from timber can be a stunning feature of a building and is essential to keep its appearance. When you spot any decay caused by water penetration it is crucial to stop it. It is best to do this by thorough painting, especially where there has been damage or deterioration. It is recommended to use paints that are specifically designed to be used as part of a system (primer undercoat, finish) and to follow the manufacturer's recommendations in relation to preparation and the amount of coats required at each stage.

Wet rot is a frequent problem in old timber windows. The best way to stop it becoming a problem is to take out any damaged or rotten parts as soon as you can to prevent the spread of the fungus responsible for it. The replacement of rotting timber should be carefully undertaken with a slow-growing deal (pine) and, wherever possible, the same species as that which is being removed to avoid differential movement between the new section and existing 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 tracery made of wood, moulded mullions and deep projecting cills. In the past, more often, the glass was set within rebated frames and pinned in with 'glazing sprigs' rather than into lead cames. This method of glazing not only makes windows less likely to leak and break, but also allows larger sheets of glass to be used than would have been possible without the use of lead lights.

Energy efficiency

The traditional timber windows are energy efficient due to their thickness and multilayer construction, as well as their care for particulars. The large glass surfaces, the deep projecting cills, and the large glazing areas reduce air infiltration. Windows can be designed to improve their energy efficiency with draught-proofing and secondary glazing. However, it is important to keep in mind that these measures should be evaluated in terms of the overall appearance and integrity of the upvc window lock repair in its original form.

As a result, retaining the existing windows from the past that are in need of repair rather than replacing them makes sense particularly when thermal enhancements can be made cost-effectively through simple repairs and upgrades. Older windows typically have a historical value that shows a variety of technological advancement and changes in architectural style. The pressure to replace these windows are typically based on the assumption that the old windows will need replacement in the near future, however the majority of them are capable of providing service for 150, 200 and even 250 years, if properly maintained.

It is crucial to recognize that the decay issues caused by traditional timber windows can be prevented by thorough maintenance and prompt repairs. It is also crucial to identify damp problems and correct them swiftly so that you can avoid serious damage. The early deterioration of paint could be a problem as it allows moisture to penetrate into the wood, leading to wet rot. It is not uncommon for this damage to go unnoticed until paintwork starts to crack or turn curly. However, it can cause structural damage and then further decay.

A quality paint will block moisture penetration. It is also important to keep the paintwork in good condition in order to prevent mould and condensation. Modern synthetic paints can be problematic, as they are often made to be water-resistant and this may result in the formation of mildew in the window frame.

The majority of windows from the past were made from timber that contained an extensive proportion of sapwood. These timbers deteriorate quickly if exposed to rain, however they can be protected with an extensive preservation treatment prior to use. It is important to choose the right type of wood for your location and the climate, since these factors can affect the durability of the joinery. Local window manufacturers create a variety of timber sash that can be adapted to fit specific openings from the past. They are available in the standard Boston pattern or in custom sizes to fit historic structures.

Maintenance

The lifespan of windows made of timber can be extended significantly by regular inspection, careful redecoration and timely repair. The major cause of decay is moisture penetration through deteriorated paint or putty. This can be prevented by using a good wood preservative and thoroughly painting the wood.

It is crucial that repairs to the old sash and casement windows are well executed, and carried out with the minimum disturbance. It is possible to repair many traditional timber window designs without taking the frame off. This should be done as often as is feasible. 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 adhere better. It is crucial to not remove old paint layers, which may have historical significance.

When a piece of wood has become rotten the best way to proceed is to eliminate the rotten material and replace it with spliced-in timber inserts that are shaped to match the existing profiles. The timber that is inserted should be treated with wood preservative and the junction between the masonry sub-cill and the timber cill should be sealed.

It's tempting to replace traditional windows with PVC u, particularly when the installer offers an all-in-one installation that includes both replacement and removal within a single day. It is important that the installers of replacement windows are aware of the history and design of traditional timber frames. This will allow them to make the appropriate recommendations for energy efficiency improvements as well as other technological improvements that don't harm the character of a historic building. Those who provide replacement windows must be registered under a Competent Persons Scheme, such as FENSA. This will ensure that the replacements are deemed acceptable under Building Regulations as a suitable option. A skilled carpenter can install PVC-u windows that conform to the original character of the building. This is especially true when windows are situated in listed buildings or conservation areas.
