Maintaining Timber Windows

A well-maintained and maintained timber window is an important element of the historic fabric of a structure. It reflects in varying degrees, the technology and materials of the time period it was made, the design and craftsmanship.

If it is possible, repairs must be made on-site. Proprietary resin-based repair systems can be used to fix the most damaged areas of decay without removing the entire window.

Durability

The windows made of timber in many historic buildings were made to last for hundreds of years. They do require some maintenance to keep them looking great. The most frequently-asked maintenance tasks include sash-cord repairs as well as tightening sash pulleys and painting. The demand for enhancing windows made of timber to increase efficiency in energy use is also growing. This may include replacing old double glazing cambridge units, repairing existing window rebates, or installing new cills to increase the air seal.

The deterioration of paintwork is a major problem with traditional windows. This is especially true when sash windows are concerned, as the gaps between sashes may be very large. In these instances water may get through the paint film and cause decay of the putty and the wood underneath. Poor weather conditions can exacerbate the rotting. To avoid this, windows should be painted regularly using an exterior wood paint that is suitable.

In addition to repainting, corroded areas must be repaired using the help of a resin-based repair solution. This will ensure that the maximum amount of original fabric is preserved. It is also necessary to reduce the number of holes you drill into the frame to allow cable entry as these can allow water in and cause decay.

The wall's structural movement can cause distortions in the frame as well as the sash. This can lead to the sash fitting incorrectly and jamming or sticking into the opening, and even broken glass. 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 strong hardwood like oak, to prevent shifting between the new and old work.

To alleviate this issue There are several companies that make Boston pattern sash made of wood that will fit most existing openings. They are available in a variety of sizes and finishes to suit the requirements of the modern homeowner. Together with quadruple draught strips and a better thermal insulation, these new sash can make a substantial difference to the energy efficiency of a home.

Aesthetics

Many old timber frames have a great aesthetic appeal, as they reflect, in some form, the materials technology, the construction process, and the architectural taste from the time period they were made. They may also have significant historical value as a set. This is particularly true for windows that were unglazed in the early days of timber-framed structures, where the majority were simply a series of openings in frames of structural construction, which were divided horizontally by mullions and vertical wood or iron bars in order to keep out invaders.

Traditional window joinery made from timber is a beautiful element of a structure and is crucial to maintain its appearance. As soon as you see any decay caused by the penetration of moisture it is essential to stop it. This is best accomplished by painting thoroughly, especially in areas where there has already been damage or degradation. It is advisable to use paints designed to be used as part of a system (primer as well as undercoat, finish and primer) and follow the manufacturer's instructions in relation to preparation and the number of coats required at each stage.

The fungus that causes wet rot can quickly spread in old windows made of wood. To prevent this, remove any rotten or damaged parts as soon as you can. Replace rotting wood with slow-grown deal (pine), and if possible, the same kind of timber that is being removed, to prevent any differential movement.

In the late the 17th and early the medieval periods, glass became more affordable and abundant, and the openings for glazed glass in timber-framed buildings gradually became more elegant with wooden tracery as well as moulded mullions and projection cills. The glazing was increasingly set within rebated frames and then pinned with 'glazing sprigs' rather than into lead cames. This method of glazing is not just less susceptible to leaks, but it also allows much wider clearer, more transparent sheets of glass to be used in windows than would otherwise be possible without the need for lead lights.

Energy efficiency

Traditional timber windows provide excellent energy efficiency due to their thickness and multi-layer construction. They also pay meticulous attention to detail. The large glass areas, deep projecting cills, and the large glazing areas minimize air infiltration. The windows can be modified to increase their energy efficiency through draughtproofing and secondary glazing. It is crucial to remember that these measures need to be taken into consideration in relation to the overall integrity and look of the original windows.

It makes sense to repair or upgrade existing windows, rather than replacing them, particularly when improvement in thermal efficiency can be achieved by simple repairs. The windows that are historic have a lot of historical value, as they demonstrate a variety in technical development and changes to architectural taste. Many people believe that the windows will need to be replaced in the near future. However, most will last for 150, 200 or even 250 years if they are maintained with proper maintenance.

It is important to recognise that the decay issues caused by traditional timber windows can be avoided by thorough maintenance and prompt repairs. In addition it is vital to recognize damp penetration issues and address them swiftly to avoid major damage. Early paint deterioration could be a problem as it allows moisture to get into the wood, causing wet rot. This damage is often not apparent until the paintwork becomes damaged or wavy, but can cause significant structural damage, and could lead to further decay.

A paint of good quality will block moisture penetration. It is also necessary to keep the paintwork in good condition in order to prevent condensation and mould growth. Modern synthetic paints pose a problem because they are often water-resistant and can cause mildew to grow in the window frame.

Most older windows were made of sapwood-rich timber. These timbers deteriorate quickly if exposed to rain, but they can be protected by an extensive preservation treatment prior to use. It is also essential to ensure that the kind of wood used is suited to the location and climate conditions, since these factors affect the durability of the joinery. Local window manufacturers offer an array of sash made from timber that can be customized to fit historic openings. They can be made according to the standard Boston pattern dimensions, or to custom sizes that are in keeping with the historic architecture.

Maintenance

The life of timber windows can be extended considerably by regular inspection carefully redecoration, and timely repair. The primary cause of wood decay is the penetration of moisture through the deteriorated paint and putty. This can be prevented by using a quality wood preservative and painting the wood thoroughly.

It is essential that upvc repairs near Me (Http://yerliakor.com/user/grounddiving6) to old sash and casement windows are well executed, and carried out without causing any disturbance. Many traditional timber window designs can be repaired without dismantling the frame, and this method should be taken whenever possible. Remove peeling or loose paint and lightly sand the surface to improve the 'key" of the surface. This will enable the new coating to adhere better. It is important to not remove old paint layers that may have historical value.

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

It can be tempting to replace traditional windows with PVC u, particularly if the installer offers an 'all-in-one' installation which includes both replacement and removal in one day. It is important that the installers of replacement windows have a thorough understanding of the history and construction of traditional timber frames. This will enable them to make appropriate recommendations for energy efficiency improvements as well as other technological improvements that don't harm the character of an historic building. The windows that are replaced must be registered under a Competent Persons Scheme like as FENSA. This will ensure that the replacements are deemed as a suitable solution under Building Regulations. A skilled carpenter can install PVC-u windows that conform to the original character of the building. This is particularly true where windows are situated in listed buildings or conservation areas.
