5 Motives Cambridge Window Is Actually A Beneficial Thing

Maintaining Timber Windows

A well-maintained wooden window is a crucial element of a building that is historic. It reflects in different degrees, the materials and technologies of the time period it was constructed, as well as the design and craftsmanship.

When repairs are feasible to existing windows are required, they should be made in-situ. The repair system that is based on resin can be used to fix the most deteriorated areas without removing the whole window.

Durability

Timber windows were built to last for hundreds of years. However, they need to be maintained to ensure that they look good and operating correctly. Maintenance tasks include repairs to sash cords and retightening pulleys on sash, and painting. There is a growing need to upgrade the timber windows to increase the efficiency of energy. This may mean replacing old glazing units, fixing the window rebates that are in place, or installing new cills to allow for better air sealing.

The corrosion of paintwork is a major problem with traditional windows. This is especially important where windows made of sash are involved because the gaps between sashes can be quite wide. In these instances water may get through the paint film and cause rotting of the putty and the wood underneath. Poor weather conditions can exacerbate the decay. To prevent this from happening, windows must be regularly painted with an exterior wood paint.

In addition to repainting, corroded areas must be repaired using an adhesive-based repair product. This will ensure that the best possible amount of the original fabric remains. It is crucial to reduce the number of holes that are drilled into the frame in order to allow cable access, because they could let in moisture 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 could result in sash no longer fitting correctly, sticking or jamming in the opening, and damaged glazing. This can be fixed frequently by putting in new frames for sash made of slow-grown deal (pine) or oak. The cill should be constructed of a durable hardwood, like oak, in order to prevent any shifting between the new and old work.

There are several companies that produce Boston pattern wooden sash that fit into the majority of existing openings. They are available in various sizes and finishes that will suit the needs of modern homeowners. The new sash, combined with quadruple draft strip and a better thermal insulation, can significantly improve the efficiency of a home's energy use.

Aesthetics

Many old timber frames have a great aesthetic appeal because they reflect, in some form, the quality of the wood, technology, and architectural aesthetics of the time they were built. They may also have significant historical significance as a set. This is particularly true for 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 with vertical wood or iron bars in order to protect against intrusions.

It is crucial to maintain the appearance of traditional timber window joinery. When window repairs cambridge spot any signs of decay caused by the penetration of moisture it is essential to stop it. This is best done by applying a thorough coat of paint, particularly in areas that have already suffered damage or deterioration. It is recommended to use paints that are designed to be used as part of a system (primer as well as undercoat, finish and primer) and follow the manufacturer's guidelines regarding preparation and the number of coats required at each stage.

Wet rot is a typical problem for old timber windows. The best way to stop it becoming a problem is to take out any damaged or rotten sections as soon as you can to prevent the spread of the fungus that causes it. Replace the wood that is rotting with slow-growing deal (pine), and if possible, the same kind of timber as the one being removed, to prevent the possibility of differential movement.

In the late period of the 17th century and the middle of the medieval period, glass became cheaper and more abundant, so that the glazed openings in timber-framed buildings gradually became more sophisticated with wooden tracery, moulded mullions and deep projection cills. In recent times, glass was fixed to frames that were rebated with glazing sprigs, not lead cames. This method of glazing not only makes windows less likely to leak and also allows larger sheets of glass to be employed than would be feasible without the use of led lights.

Energy efficiency

Traditional timber windows are energy efficient due to their thickness, multilayer construction and attention to particulars. They also have large glass areas as well as deep projection cills which reduce air infiltration. With secondary glazing and draught proofing, windows can be upgraded to increase their energy efficiency. However it is crucial to keep in mind that these measures must be considered in terms of the overall appearance and integrity of the window in its original form.

It is logical to repair or upgrade existing windows, rather than replacing them, particularly when improvements in thermal efficiency can be made by simple repairs. Historic windows often have historical significance that illustrates a variety of technical development and changes in architectural taste. The pressure to replace these windows are generally based on the assumption that the windows that are old will need to be replaced in the near future, however most are still capable of providing service 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 timber windows can be prevented by regular maintenance and timely repairs. It is also essential to recognize damp issues and correct them swiftly in order to avoid major damage. Paint deterioration that occurs early is a concern because it allows moisture to penetrate into the wood, leading to wet rot. It is not uncommon for this type of damage to go unnoticed until paintwork begins to crack or become wavy. However, it can cause structural damage and further decay.

A high-quality paint will stop this moisture penetration. To prevent condensation and mould it is crucial to keep the paintwork as clean as you can. Modern synthetic paints pose a problem because they are often water-resistant and may cause mildew growth within the window frame.

The majority of older windows were constructed from timber with a high proportion of sapwood. These timbers deteriorate quickly if exposed to rain, however they can be protected with a thorough preservation process prior to use. It is also essential to ensure that the kind of timber used is well-suited to the location and climate conditions, as these elements will influence the durability of the joinery. Local window manufacturers provide a wide range of sash timbers that can be adapted to fit historical openings. They can be constructed according to the standard Boston pattern dimensions or to specific dimensions that are compatible with historic buildings.

Maintenance

The lifespan of windows made of timber can be extended considerably by regular inspection carefully redecoration, and prompt repair. The primary cause of wood decay is the penetration of moisture through deteriorated paint or putty. This can be avoided by careful painting and using high-quality wood preservative.

It is crucial that repairs to old sash or casement windows are well executed, and carried out without causing any disturbance. Many traditional timber window designs can be repaired without removing the frame, and this option should be taken whenever feasible. Remove peeling or loose paint and lightly sand the area to improve the 'key" of the surface. This will enable the new coating to adhere better. It is crucial to not remove old paint layers, as they may have historical significance.

If a piece of timber is rotten, the best way to proceed is to take out the rotten material and replace it with spliced-in timber inserts that are shaped to fit the existing profiles. The wood that is inserted should be treated with a wood preservative and the joint between the cill for timber and the sub-cill for masonry should be sealed.

Replacement of traditional windows with PVC-u is a tempting option, especially when the installer offers a 'one stop shop' installation that takes care of removal and replacement within a day. It is crucial that the person who installs windows replacement has a thorough knowledge of the structure and history of traditional timber frames. This will enable them to make the right recommendations for energy efficiency improvements and other technical upgrades that won't harm the character of a historic building. Those who provide replacement windows should be registered with a Competent Persons Scheme such as FENSA. This will ensure the replacements are deemed acceptable by the Building Regulations as a suitable option. A skilled carpenter can install PVC-u windows that are suited to the original character of the building. This is especially true when windows are installed in listed buildings and conservation areas.
