Maintaining Timber Windows

A well-maintained timber window is a crucial part of the historic fabric of a building. It reflects, in various degree the materials and techniques of the time period it was constructed, as well as the craftsmanship and architectural taste.

If possible, repairs should be made in-situ. Repair systems made of resin can be used to repair the most deteriorated areas without having to remove the entire window.

Durability

Timber windows were made to last for hundreds of years. They do require some maintenance to keep them looking great. The most frequent maintenance tasks are repairs to sash-cords, re-tightening sash pulleys, and painting. There is also a rising demand to upgrade the timber windows to improve energy efficiency. This could mean replacing old glass units, fixing existing window rebates or putting in new cills for improved air sealing.

The deterioration of paintwork is a major issue with traditional windows. This is particularly important in the case of sash windows, as the gaps between sashes can often be very large. In these circumstances water can get into the paint film and cause rotting of the putty and underlying wood. The rotting can be exacerbated due to weather conditions that are poor. To stop this from happening windows from becoming rotten, they must be regularly painted with an exterior wood paint that is suitable.

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 maximum possible amount of the original fabric is preserved. It is important to minimize the number of holes that are created in the frame to allow cable access, because they could let in moisture and cause decay.

Another issue with older windows is the structural movement within the wall which can cause deformation of the frame and the sash. This could result in the sash fitting incorrectly, jamming or sticking in the opening, and even broken glass. This is often corrected by putting in new sash frames made of slow-grown deal (pine), or oak. The cill must be constructed from a sturdy hardwood such as oak to avoid any movement between the old and new work.

To alleviate this issue, there are now a number of companies who produce Boston pattern sash made of wood that can be fitted into most openings. The sash is available in a variety of sizes and finishes that meet the requirements of modern-day homeowners. Combined with quadruple draught strips and a better thermal insulation, these new sash options can make significant improvements to the energy efficiency of your home.

Aesthetics

Many old wooden windows have an excellent aesthetic value since they usually illustrate, in some way, the materials and technology and architectural style of the time from when they were built. They could also have a significant historic value in their in their own right. This is particularly true for windows that were unglazed in the early days of timber-framed buildings, in which the majority were simply a series of openings within frames of structural construction, which were divided horizontally by mullions with vertical wood or iron bars in order to protect against invaders.

Traditional window joinery made of timber can be a stunning element of a structure and is essential to maintain its appearance. As soon as you notice any signs of decay caused by moisture penetration it is essential to stop it. It is recommended to do this through thorough painting, especially if there has been damage or deterioration. It is best to use paints designed to be used in a set (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 windows made of timber. To prevent this from happening, take out any damaged or rotten components as soon as you can. The replacement of wood that is rotting should be done with care and using slow grown deal (pine) and, whenever feasible using the same species as that which is being removed to avoid differential movement between the new section and existing timbers.

Glass became less expensive and more abundant in the late medieval period and into the 17th century. As a result, the openings for double glazed Door seal repairs (https://emplois.fhpmco.fr) windows on timber-framed houses became more complicated with moulded mullions, tracery made of wood and cills that protruded deep. In recent times, glass repair cambridge was pinned into rebated frames with glazing sprigs, not lead cames. This method of glazing is not only less susceptible to leaks, but it can allow for much wider, clearer sheets of glass to be used in windows than would have been possible without the need for lead lights.

Energy efficiency

Traditional timber windows are energy efficient due to their thickness, multilayer construction and attention to the smallest of details. They also feature large glass areas and projecting cills that minimise air infiltration. The windows can be modified to increase their energy efficiency by draught-proofing and secondary glazing. It is essential to remember that these measures must be taken into consideration in relation to the overall integrity and appearance of the original windows.

As a result, retaining the existing windows from the past that require repair instead of replacing them is logical especially when their thermal improvements can be achieved cost-effectively through simple repairs and improvements. Older windows typically have an historic value that demonstrates a range of technological advances and changes in architectural style. The pressures to replace these windows are typically based on the assumption that the windows that are old will need to be replaced in the near future, but the majority of them are in a position to last for 150, 200 or even 250 years if they are properly maintained.

It is essential to realize that decay issues with traditional timber windows can be preventable by prompt and thorough repairs. It is also crucial to identify damp problems and fix them quickly so that you can avoid serious damage. The early deterioration of paint can be a problem because it allows moisture to penetrate into the wood, causing wet rot. It is not uncommon for this issue to go undetected until the paintwork begins to crack or become wavier. However, it could cause structural damage and then further decay.

A high-quality paint will stop this moisture penetration. It is also important to keep the paintwork spotless to avoid mould and condensation. Modern synthetic paints pose a challenge because they are water-resistant and may cause mildew growth in the window frame.

The majority of windows from the past were manufactured from timber containing an extensive proportion of sapwood. The timbers will deteriorate rapidly if exposed to rain, but they can be protected by a thorough preservation treatment before use. It is also crucial to ensure that the type of wood used is suited to the site and climate conditions, as these factors can affect the longevity of the joinery. Local window manufacturers have various types of sash timbers that can be adapted to fit historical openings. They can be built according to the standard Boston pattern dimensions or to specific dimensions that are compatible with the historic architecture.

Maintenance

The life of timber windows can be extended considerably by regular inspection carefully redecoration, and prompt ventilation repair cambridgeshire. The primary cause of wood decay is moisture leaking through deteriorated paint or putty. This can be avoided with careful painting and the use of an excellent wood preservative.

Be careful to avoid stripping old paint layers that might have historical significance If these are present, it is recommended that a study of the paint be carried out.

If a piece of wood has rotted the best option is to take it off and replace it with timber inserts designed to match existing profiles. The timber inserts should be treated with a wood preservative, and the joint between masonry sub-cill and timber cill should be sealed.

It is tempting to replace traditional windows with PVC U, particularly when the installer provides an 'all-in-one' installation which includes removal and replacement in one day. It is, however, essential that the person installing windows replacement has a thorough knowledge of the structure and history of traditional timber frames. This will allow them to make appropriate recommendations for energy-efficiency improvements and other technological advancements that won't harm the character of an historic building. The window installers who provide replacement windows must be registered with a Competent Persons Scheme like FENSA. This will ensure the replacements are approved by the Building Regulations as a suitable alternative. A skilled carpenter can install PVC-u Windows that are sympathetic to original building's character. This is particularly applicable when windows are situated within listed buildings or conservation areas.
