Maintaining Timber Windows

A well-maintained and maintained timber window is a significant element of the historical fabric of a structure. It reflects in different degree the technology and materials of the time it was made, the craftsmanship and architectural taste.

When possible, upvc door handle repairs near me (olderworkers.com.au) should be made on-site. Repairing the most severe areas of decay can be done with the help of specialized resin-based systems.

Durability

Timber windows were built to last for centuries. They require regular maintenance to keep them looking good. Maintenance tasks include repairs to sash cables, retightening of pulleys on sash, and painting. There is also a rising demand for upgrading timber windows to improve energy efficiency. This can involve replacing old glazing units, repairing existing window rebates or putting in new cills to allow the air to seal better.

A key problem with traditional windows is the damage caused by the corrosion of the paintwork. This is particularly true when windows with sash are involved since the gaps between sashes can be quite wide. In these instances water can enter the paint film and cause rotting of the wood or putty beneath. Poor weather conditions can exacerbate the decay. To prevent this from happening, windows must be painted regularly with an exterior wood paint.

In addition to repainting, areas that have corroded should be repaired with a resin-based repair product. This will ensure the maximum amount of the original fabric is preserved. It is crucial to reduce the number of holes that are created in the frame to allow cable entry, 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 the sash. This can lead to the sash not fitting properly and jamming or sticking into the opening, and even broken glass. This is often corrected by putting in new sash frames made of slow-growing deal (pine) or oak. The cill needs to be constructed of a durable hardwood, like oak, in order to prevent any the movement of new and older work.

To help reduce this problem There are a variety of companies that produce Boston pattern sash made of wood that will fit most existing openings. The sash is available in various sizes and finishes to meet the requirements of modern-day homeowners. Combined with quadruple draught strips and better thermal insulation these sashes can make a an enormous difference to the energy efficiency of a house.

Aesthetics

Many old timber frames have a high aesthetic appeal, as they display, in a certain shape, the materials, technology, and architectural aesthetics of the time they were constructed. They could have significant historical significance in their own right. This is particularly true for early windows that were not glazed in timber-framed buildings, where the majority were series of openings in structural frames that were subdivided horizontally by mullions, and vertically by iron or wood bars in order to protect against intrusions.

Traditional timber window joinery can be a stunning element of a structure and it is important to keep its appearance. It is crucial that any decay caused by water penetration is stopped as soon as it is discovered. This is best accomplished by a thorough painting process, especially in areas that have already suffered damage or degradation. It is best 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 coats at each stage.

Wet rot is a typical problem in old timber windows. The best method to stop it from growing is to eliminate any damaged or rotten sections as soon as possible to stop the spread of the fungus that causes it. The replacement of wood that is rotting should be carefully undertaken with a slow-growing deal (pine) and, whenever feasible using the same species as that which is being removed to prevent shifting between the new section and the 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 elegant with wooden tracery moulded mullions, moulded mullions, and deep protruding cills. Increasingly, the glazing was set within rebated frames and then pinned with 'glazing sprigs' rather than being inserted into lead cames. This method of glazing not only makes the windows less likely to leak and also allows more clear glass sheets to be used than would have been possible without the use of led lights.

Energy efficiency

Traditional timber windows provide excellent energy efficiency due to their thickness, multi-layer construction and very attentive attention to detail. They also have large glass areas and deep projecting cills that minimise air infiltration. With secondary glazing and draughtproofing, windows can be upgraded to improve their energy efficiency. It is essential to remember that these measures need to be taken into consideration in relation to the overall appearance and integrity of the original windows.

It is sensible to fix or upgrade historic windows rather than replace them, particularly when improvements in energy efficiency can be made by simple repairs. Older windows typically have historical significance that demonstrates a range of technological advances and changes in architectural taste. Most people think that these windows will need to be replaced in the near future. However, most can still provide service for 150, 200, or even 250 years if you take care of maintenance.

It is important to recognize that decay issues associated with traditional timber windows can be avoidable with prompt and thorough repairs. Additionally it is vital to spot damp penetration issues and to remedy them quickly to avoid serious damage. The early deterioration of paint is a major issue, because it allows moisture to penetrate the wood and cause wet rot. It is not uncommon for this damage to go unnoticed until paintwork starts to crack or turn wavy. However, it could cause structural damage and lead to further decay.

A good quality paint will stop this moisture from entering. To prevent mould and condensation it is essential to keep the paintwork as clean as it can be. Modern synthetic paints could be a problem because they are usually made to be water-resistant and this can cause the growth of mildew inside the window frame.

The majority of older windows were constructed from timber with a high proportion of sapwood. The timbers will deteriorate rapidly if exposed to rain, however they can be protected by an extensive preservation treatment prior to use. It is essential to select the right type of wood for your location and the climate, since these factors can affect the longevity of the joinery. Local window manufacturers produce various types of timber sash that can be adapted to fit specific openings in historic buildings. They can be constructed to the standard Boston pattern dimensions or to custom dimensions that are compatible with the architectural style of historic buildings.

Maintenance

The life span of windows made from timber can be extended by regular inspection as well as a careful redecoration and prompt repair. The primary reason for the decay is the infiltration of moisture through the deterioration of paint and putty. This can be avoided by thorough painting and the use of an excellent wood preservative.

It is essential that repairs to old sash or aluminium casement windows cambridge windows are well executed, and carried out with minimal disruption. Many of the traditional designs for timber windows can be repaired without dismantling the frame, and this approach should be taken whenever possible. Remove peeling or loose paint and lightly sand the surface to improve the 'key" of the surface. This will allow the new coating to adhere better. It is important to avoid stripping old paint layers that could have historical value If these are present, it is recommended that a study of the paint be conducted.

Where a section of timber is rotten, the best way to proceed is to eliminate the rotten material and replace it with spliced-in timber inserts that are shaped to match existing profiles. The inserted timber should also be treated using wood preservative. The junction between the masonry sub-cill and the timber cill should be sealed.

Replacement of windows made of traditional PVC-u may be an attractive option, especially when the installer provides a 'one stop shop' installation that handles removal and replacement in a day. It is important that the installers of replacement windows have a thorough understanding of the history and design of traditional timber frames. This will allow them to make appropriate suggestions for improvements to energy efficiency and other technological upgrades that do not alter the historical character of a building. Anyone who installs replacement windows should be registered with a Competent Persons Scheme such as FENSA. This will ensure that the replacements are deemed to be approved in accordance with Building Regulations as a suitable option. A skilled carpenter can install PVC-u windows that conform to the original building's style. This is particularly true where the windows are located in listed buildings or conservation areas.
