Maintaining Timber Windows

A well-maintained wooden window is an essential component of a historical building. It is a representation of the various materials and techniques as well as the craftsmanship and architectural style of the time period that it was built in.

Whenever possible repairs to existing windows are required, they should be done in situ. Proprietary resin-based repair systems can be used to repair the most damaged areas of decay without having to remove the entire window.

Durability

Timber windows were designed to last for hundreds of years. But, they have to be maintained to keep them looking good and operating correctly. The most frequent maintenance tasks include sash-cord repairs, re-tightening sash pulleys, and painting. There is also a growing demand for upgrading timber windows to increase energy efficiency. This may include replacing old glazing units, repairing the window rebates that are in place or installing new cills to increase the air seal.

The deterioration of paintwork is a major problem with traditional windows. This is particularly important when sash windows are involved as the gaps between sashes can be extremely wide. In these instances, water can penetrate paint film and cause rotting to the wood or putty beneath. Weather conditions that are not ideal can accelerate the rotting. To prevent this windows from becoming rotten, they must be painted regularly using a suitable exterior wood paint.

In addition to repainting, areas that have corroded should be repaired with a resin-based repair product. This will ensure that the greatest amount of original fabric retained. It is also essential to reduce the number of holes you drill into the frame to allow cable entry since these could let in water and cause decay.

The structural movement of the wall can cause deformations in the frame and the sash. This could result in sash no longer fitting correctly and jamming or sticking to the opening and broken glazing. Most often, this is corrected by the fitting of new sash boxes constructed from slow-growing deal (pine) or oak. The cill should be constructed from a sturdy hardwood such as oak to avoid any movement between the old and new work.

To help reduce this problem There are a number of companies who make Boston pattern sash made of wood that will fit into the majority of existing openings. The sash is available in a range of sizes and finishes that meet the requirements of the modern homeowner. Together 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 windows have a high aesthetic value since they usually show, in a particular way, the materials and technology and architectural taste of the time in which they originate. They also may have significant historical value in their individual cases. This is especially true for early unglazed window openings in timber-framed structures, which were merely a series of openings in the frame, which were divided horizontally into mullions, and vertically into wood or iron bars to keep out intruders.

Traditional Upvc Window Renovation (Www.Cheaperseeker.Com) joinery made from timber can be a stunning element of a structure and is crucial to keep its appearance. It is crucial that any decay resulting from water penetration is removed as soon as it is recognised. This is best accomplished by applying a thorough coat of paint, particularly in areas in which there is already damage or degradation. It is recommended to use paints that are designed to be used in a set (primer undercoat and finish) and to follow the manufacturer's guidelines for preparation and number of coats at each stage.

The fungus responsible for wet rot can quickly spread in old windows made of timber. To prevent this from happening, take out any damaged or rotten parts as quickly as you can. The replacement of wood that is rotting must be done with care with a slow-growing deal (pine) and, if possible it is the same species as that which is being removed to avoid differential movement between the new section and the existing timbers.

Glass became less expensive and more abundant during the late medieval period and into the 17th century. As a result, glazed openings on timber-framed houses became more complex with moulded mullions, tracery made of wood and cills that protruded deep. In recent years, glass was fixed into frames that were rebated using double glazing near me sprigs rather than lead cames. This method of glazing is not only less susceptible to leaks, but it also allows more expansive, clearer sheets of glass to be used in the windows than would otherwise have been possible without the need for leaded lights.

Energy efficiency

Traditional timber windows provide a good energy performance due to their thickness and multi-layer construction. They also pay careful attention to detailing. They also have large glass areas and deep projecting cills that minimise air infiltration. With secondary glazing and draught proofing, windows can be made more efficient to improve their energy efficiency. However, it is important to keep in mind that these measures should be evaluated in the context of the overall integrity and appearance of the original window.

It is logical to repair or upgrade existing historic windows rather than replace them, particularly when improvement in thermal efficiency can be achieved by simple repairs. The windows of the past often have a historical value that illustrates a variety of technological advances and changes in architectural taste. Most people think that the windows will need to be replaced in the near future. However, most are still in service for 150, 200 or even 250 years if you take care of maintenance.

It is important to recognize that decay issues in traditional timber windows are preventable by quick and thorough repairs. Additionally, it is essential to identify damp penetration problems and to remedy them quickly to avoid serious damage. The early deterioration of paint is a concern because it allows moisture to get into the wood, causing wet rot. It is not uncommon for this damage to go undetected until the paintwork starts to crack or turn curly. However, it can cause structural damage and then further decay.

A quality paint will block moisture penetration. To avoid condensation and mould it is essential to keep the paintwork as clean as you can. Modern synthetic paints are problematic since they are usually water-resistant and can cause mildew to develop in the window frame.

The majority of older windows were made from timber that contained a high proportion of sapwood. These timbers deteriorate quickly if exposed to rain, but they can be preserved with a thorough preservation treatment before use. It is also crucial to ensure that the kind of wood used is suitable to the location and climate conditions, since these factors affect the durability of the joinery. Local window manufacturers provide a wide range 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 architectural style of historic buildings.

Maintenance

Regular inspection as well as careful redecoration and quick repairs can prolong the lifespan of windows made of timber.

It's tempting to replace traditional windows with PVC u, particularly when the installer provides an all-in-one installation that includes both replacement and removal in one day. It is, however, crucial that the person who installs replacement windows has a full knowledge of the construction and history of traditional timber frames. This will enable them to make the right recommendations for energy efficiency improvements as well as other technological advancements that won't affect the appearance of a building that is historic. Those providing replacement windows should be registered with a Competent Persons Scheme such as FENSA. This will ensure that the replacement windows are approved as a suitable solution under Building Regulations. A skilled carpenter can install PVC-u Windows that are sympathetic to original building's character. This is especially true where the windows are located in listed buildings or conservation areas.
