Maintaining Timber Windows

A well-maintained wooden window is a crucial component of a historical building. It reflects in varying degree the technology and materials of the time in which it was made, the design and craftsmanship.

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

Durability

Timber windows were built to last for hundreds of years. They require regular maintenance to keep them looking good. The most frequently-asked maintenance tasks include sash-cord repairs as well as tightening sash pulleys and painting. There is a growing need to upgrade timber windows to improve energy efficiency. This can include replacing old glazing units, fixing the window rebates that are in place or installing new cills to improve air seal.

One of the main issues with traditional windows is damage caused by corrosion of the paintwork. This is particularly true when sash windows are involved as the gaps between the sashes can be very wide. In these situations water may get through the paint film and cause rotting of the putty and the wood beneath. The rotting may be further aggravated by poor weather conditions. To stop this from happening, windows must be painted regularly with an exterior wood paint.

In addition to repainting, corroded areas need to be repaired with the help of a resin-based ventilation repair cambridgeshire solution. This will ensure that the best possible amount of the original fabric remains. It is important to minimize the number of holes that are drilled in the frame to allow cable entry, because they could let in moisture and cause decay.

Another significant problem with older windows is the structural movement within the wall that can cause deformation of the frame and sash. This can result in the sash not fitting properly, jamming or sticking in the opening, and broken glass. This is often corrected by fitting new frames for sash made of slow-grown deal (pine) or oak. The cill must be made of a durable hardwood, such as oak, in order to prevent any shifting between the new and older work.

To reduce the risk There are a variety of companies that produce Boston pattern wooden sash that will fit into the majority of existing openings. They are available in a variety of sizes and finishes to meet the requirements of modern-day homeowners. These new sash, when combined with quadruple draft strip and improved thermal insulation can significantly improve the efficiency of a home's energy use.

Aesthetics

Many old wooden windows have an excellent aesthetic value because they typically illustrate, in some way the materials and techniques and architectural taste of the time from which they date. They could have significant historical value on their own. This is particularly true of early windows that were not glazed in timber-framed buildings, 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 to keep out intruders.

Traditional window joinery made from timber is a beautiful aspect of a building, and it is important to keep its appearance. It is vital that any decay caused by moisture penetration should be stopped as soon as it is discovered. It is best to do this through thorough painting, especially where there has been damage or degradation. It is advisable to use paints that are designed to be used as part of a system (primer, undercoat and finish) and follow the manufacturer's instructions in relation to preparation and the amount of coats required at each stage.

Wet rot is a common issue in old timber windows and the best way to stop it becoming a problem is to take out any damaged or rotten parts as soon as you can to stop the spread of the fungus that causes it. The replacement of wood that is rotting should be done with care and by using a slow-growing deal (pine) and, if feasible it is the same species as which is being removed to prevent differential movement between the new section and the existing timbers.

In the late medieval and 17th century periods glass became more affordable and abundant, so that the glazed openings in timber-framed buildings gradually became more sophisticated with wooden tracery moulded mullions, moulded mullions, and deep projecting cills. In recent times, glass was fixed to frames that were rebated using glazing sprigs, not lead cames. This method of glazing is not just less prone to leaking but it also allows larger, clearer sheets of glass to be used in the windows than would be possible without the need for leaded lights.

Energy efficiency

The traditional timber windows are energy efficient due to their thickness and multilayer construction as well as care for detail. The large glass areas, deep projecting cills and large glazing areas minimize air infiltration. With secondary glazing and draught proofing, windows can be made more efficient to increase their energy efficiency. It is essential to remember that these measures must be taken into consideration when it comes to the overall integrity and look of the original windows.

Therefore, keeping existing historic windows that are in need of repair instead of replacing them makes sense particularly when thermal improvements can be achieved inexpensively with simple repairs and improvements. Historic windows often have an historic value that shows a variety of technological advances and changes in architectural tastes. The pressures to replace such windows are typically based on the assumption that old windows will need replacement in the near future, but they are in a position to last for 150, 200 and even 250 years if properly maintained.

It is important to recognize that decay issues with traditional timber windows are easily prevented with timely and thorough repairs. It is also important to identify damp problems and fix them quickly in order to avoid major damage. The early deterioration of paint is a concern because it allows moisture to get into the wood, which can cause wet rot. It is not uncommon for this issue to go unnoticed until paintwork begins to crack or becomes curly. However, it could cause structural damage and further decay.

A good paint 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 challenge because they are water-resistant, and can cause mildew growth within the window repairs near me frame.

The majority of windows from the past were made from timber that contained the majority of sapwood. The timbers will deteriorate quickly when exposed to wet weather conditions, but they can be protected by a thorough preservative treatment before they are used. It is crucial to select the appropriate type of wood for the location and climate, as these variables can affect the durability of the joinery. Local window manufacturers have various types of sash timbers that can be adapted to fit historical openings. They can be constructed according to the standard Boston pattern dimensions, or to custom dimensions that are compatible with the historic architecture.

Maintenance

Regular inspections as well as careful redecoration and quick repairs can prolong the lifespan of windows made of timber. The most common cause of decay is the infiltration of moisture through the deterioration of paint and putty. This can be avoided by using a quality wood preservative and painting the wood thoroughly.

It is essential that repairs to old sash and casement windows are well executed, and carried out with the minimum disturbance. It is possible to ventilation Repair cambridgeshire several traditional designs of timber windows without having to remove the frame. This should be done as often as is feasible. Peeling or loose paint should be removed with care and sanded lightly to increase the "key" of the surface and facilitate a better adhesion of the new coating. It is important to avoid stripping paint layers that might have historical significance, and where these are present, it is recommended that a paint analysis be conducted.

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

It is tempting to replace traditional windows with PVC U, particularly when the installer provides an installation that includes removal and replacement within a single day. However, 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 appropriate suggestions for energy efficiency improvements and other technical upgrades that will not harm the historical character of a building. Anyone who installs replacement windows should be registered with a Competent Persons Scheme like as FENSA. This will ensure that the replacements are approved as a suitable option under Building Regulations. A skilled carpenter is able to install PVC-u Windows that are sympathetic to the original building's style. This is especially true where windows are situated in listed buildings and conservation areas.
