Maintaining Timber Windows

A well-maintained wooden windows and doors Cambridge window repair specialists is a crucial element of a building that is historic. It reflects in varying degree the technology and materials of the time period it was made, the craftsmanship and architectural taste.

When possible, repairs should be made on-site. The repair system that is based on resin can be used to fix the worst areas of decay without having to remove the entire window.

Durability

The windows made of wood in many old buildings were built to last for centuries. However, they do need to be maintained to ensure that they look good and operating properly. The most frequently-asked maintenance tasks include sash-cord repairs, re-tightening sash pulleys, and painting. The demand for enhancing windows made of timber to improve efficiency and energy efficiency is also increasing. This may mean replacing old glass units, fixing existing window rebates or putting up new cills that allow for better air sealing.

The deterioration of paintwork is a major problem with traditional windows. This is particularly true when sash windows are involved as the gaps between the sashes can be extremely wide. In these circumstances, water can penetrate the paint film and cause rotting of the putty as well as the wood beneath. Poor weather conditions can exacerbate the decay. To stop this from happening, windows need to be regularly painted with an exterior wood paint.

In addition to repainting, corroded areas should be repaired with the help of a resin-based repair solution. This will ensure that the maximum amount of original fabric is preserved. It is crucial to reduce the number of holes created in the frame to allow cable entry since they can let in moisture and cause decay.

Another issue with older windows is the structural movement within the wall that can cause deformation of the frame and the sash. This can lead to the sash fitting incorrectly and jamming or sticking into the opening, or breaking glass. This can often be fixed through the installation of new sash boxes that have been made from slow grown deal (pine) or oak. The cill must be constructed from durable hardwood such as oak to avoid differential movement between the existing and new work.

There are now several companies that manufacture Boston pattern wooden sash to fit in with the majority of openings. The sash is available in a variety of sizes and finishes to meet the needs of today's homeowner. The new sash, coupled with quadruple draft strips and a more efficient thermal insulation, could make a huge difference to the efficiency of your home's energy usage.

Aesthetics

Many old timber windows have a great aesthetic value because they typically illustrate, in some way the materials and technologies and architectural taste of the time from which they date. They also may have a significant historic value in their own right. This is particularly true for early windows that were not double glazed door seal repairs in timber-framed buildings, in which the majority were simply a series of openings within structural frames that were subdivided horizontally by mullions, and vertically by iron or wood bars to protect against intrusions.

It is crucial to maintain the appearance of traditional wooden window doctor near me joinery. It is crucial that any decay resulting from water penetration is immediately stopped once it is discovered. It is best to do this through thorough painting, especially if there is damage or deterioration. It is recommended to use paints that are designed to be used in a system (primer undercoat and finish) and adhere to the manufacturer's recommendations for preparation and number of coats at each stage.

The fungus that causes wet rot is able to spread quickly in old windows made of timber. To prevent this, remove any rotten or damaged parts as soon as you can. The replacement of wood that is rotting should be done with care and by using a slow-growing deal (pine) and, if possible using the same species as that which is being removed to prevent any movement differences between the new section and existing timbers.

In the late medieval and 17th century periods glass became more affordable and abundant, and the openings for glazed glass in timber-framed buildings gradually became more sophisticated, with tracery made of wood moulded mullions, moulded mullions, and deep protruding cills. The glazing was increasingly laid within rebated frames and pinned in with 'glazing sprigs' rather than into lead cames. This method of glazing is not only less susceptible to leaks, but also allows for much wider clearer, more transparent sheets of glass to be used in windows than would otherwise be possible without the need for leaded lights.

Energy efficiency

The traditional timber windows are energy efficient because of their thickness, multilayer construction and focus on particulars. They also have large glass areas and deep projecting cills that minimise air infiltration. With secondary glazing and draught proofing, windows can be upgraded to improve their energy efficiency. It is essential to remember that these measures must be taken into consideration in relation to the overall integrity and look of the original windows.

So, retaining existing historic windows cambridge that are in need of repair rather than replacing them is sensible especially when their thermal enhancements can be achieved economically through simple repairs and improvements. Historic windows often have a historical value that shows a variety of technical development and changes in architectural tastes. The pressures to replace these upvc windows cambridge are usually based on the assumption that windows of the past will require replacement in the near future, but they are capable of providing service for 150, 200 and even 250 years if they are properly maintained.

It is important to recognize that decay problems with traditional timber windows are avoidable with timely and thorough repairs. It is also important to identify damp problems and correct them swiftly to avoid major damage. Paint deterioration that occurs early is a concern because it allows moisture to get into the wood, which can cause wet rot. The damage is usually not evident until the paintwork becomes wavy or cracked, but can cause significant structural damage and lead to further decay.

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

The majority of windows from the past were constructed 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 important to ensure that the type of timber used is well-suited to the site and climate conditions, since these factors will influence the durability of the joinery. Local window manufacturers provide various types of sash made from timber that can be made to fit the historic openings. They are available in the standard Boston pattern or in custom sizes to fit the architectural style of historic structures.

Maintenance

Regular inspections as well as careful redecoration and quick repairs can prolong the lifespan of windows made of timber. 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 a good quality wood preservative.

Repairs to old sash windows as well as window frames made of casement must be done with care and minimal disruption. Many of the traditional designs for timber windows are repairable without removing the frame, and this method should be taken whenever feasible. Remove loose or peeling paint and then lightly sand the surface to improve the 'key" of the surface. This will enable the new coating to adhere better. Be careful to avoid stripping paint layers that might have historical significance If these are present, it is recommended that a paint analysis be conducted.

If a piece of wood has rotted, the best solution is to remove it and replace it with timber inserts that are shaped to match the existing profiles. The timber inserts should be treated using wood preservative. The junction between masonry sub-cills and timber cill should be sealed.

It is tempting to replace traditional windows with PVC U, particularly when the installer offers an 'all-in-one' installation which includes removal and replacement within a single day. It is, however, crucial that the person who installs windows replacement has a thorough understanding of the construction and history of traditional wooden frames. This will allow them to make appropriate suggestions for energy efficiency improvements and other technological upgrades that do not alter the historic character of a building. The windows that are replaced should be registered under a Competent Persons Scheme such as FENSA. This will ensure that the replacements are approved as a suitable solution under Building Regulations. A skilled carpenter can put in PVC-u windows that are suited to the original character of the building. This is particularly true where windows are situated in listed buildings and conservation areas.
