All The Details Of Cambridge Window Dos And Don'ts

Maintaining Timber Windows

A well-maintained wooden window is an essential part of a historic building. It reflects in varying degrees, the materials and techniques of the time it was constructed, as well as the design and craftsmanship.

When repairs are feasible to windows that are already in use should be done in-situ. Repairing the most severe areas of decay can be done by using specialized resin-based systems.

Durability

The timber windows in many historic structures were designed to last for hundreds of years. They do require maintenance to ensure they look good. Maintenance tasks include repairs to sash cables, retightening of pulleys for sash and painting. There is also a rising demand to upgrade the timber windows to improve energy efficiency. This may mean replacing old glass repair cambridge units, repairing the window rebates that are in place, or installing new cills for improved air sealing.

The deterioration of paintwork is a major issue with traditional windows. This is particularly important when it comes to sash windows as the gaps between sashes can be very large. In these instances water can get into the paint film and cause rotting of the putty as well as underlying wood. The rotting can be exacerbated due to weather conditions that are poor. To avoid this, windows should be painted regularly with a suitable exterior wood paint.

In addition to repainting, corroded areas should be repaired with an adhesive-based upvc door repair product. This will ensure that the maximum amount of the original fabric is retained. It is also essential to minimise the number of holes that are drilled into the frame for cable entry since these could allow water in and cause decay.

The structural movement of the wall can cause distortions in the frame and sash. This can result in the sash not fitting properly or sticking or jamming into the opening, and damaged glazing. Often this can be corrected by the fitting of new sash boxes that have been made from slow grown deal (pine) or oak. The cill must be made from a sturdy hardwood, like oak, in order to prevent any differential movement between new and old work.

To reduce the risk, there are now a variety of companies that make Boston pattern sash made of wood that will fit most existing openings. They are available in a variety of sizes and finishes to meet the requirements of the modern homeowner. Together with quadruple draught strips and improved thermal insulation, these new sash can make a substantial difference to the energy efficiency of your home.

Aesthetics

Many old timber frames possess a dazzling aesthetic appeal, as they reflect, in some form, the quality of the wood technology, the construction process, and the architectural aesthetics of the time they were constructed. They may also have significant historical value on their own. This is particularly true of early windows that were not glazed in timber-framed buildings, in which the majority were simply a series of openings in frames of structural construction, which were divided horizontally by mullions with vertical wood or iron bars in order to keep out intrusions.

It is important to maintain the appearance of traditional wooden window joinery. As soon as you see any signs of decay due to water penetration, it is important to stop it. It is best to do this through thorough painting, especially where there has been damage or degradation. It is advisable to use paints specifically designed to be used as part of a system (primer, undercoat and finish) and to follow the manufacturer's recommendations in relation to preparation and number of coats needed at each stage.

The fungus responsible for wet rot can spread quickly in old timber windows. To prevent this from happening, remove any damaged or rotten components as promptly as you are able to. Replace the wood that is rotting with slow-growing deal (pine), and if possible, the same type of wood that is being removed, to prevent differential movement.

Glass became cheaper and more abundant during the late medieval period and into the 17th century. In the process, the glazed openings in timber-framed homes became more complicated with moulded mullions, wooden tracery and cills that protruded deep. The glazing was increasingly set within rebated frames and pinned in with 'glazing sprigs' rather than being inserted into lead cames. This method of cambridge double glazing is not only less prone to leaking but also allows for 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 are energy efficient because of their thickness and multilayer construction as well as focus on the smallest of details. The large glass surfaces, the deep projecting cills, and the large glazing areas minimize air infiltration. With secondary glazing and draught proofing, windows can be made more efficient to improve their energy efficiency. It is essential to keep in mind that these measures must be taken into consideration in relation to the overall integrity and look of the original windows.

It is sensible to fix or upgrade windows that are older rather than replacing them, especially when the improvements in thermal efficiency can be made by simple repairs. Older windows are usually of historical significance, since they demonstrate a variety in technological advancements and changes to architectural taste. Most people think that these windows will need to be replaced in the door seal repair near me future. However, they can still provide service for 150, 200 or even 250 years with proper maintenance.

It is crucial to understand that decay issues in traditional timber windows are preventable by prompt and thorough repairs. Additionally, it is essential to identify damp penetration problems and address them swiftly to avoid serious damage. The early deterioration of paint is a major problem because it allows moisture to penetrate the wood and cause wet rot. This damage is often not evident until the paintwork is cracking or wavy, but can cause significant structural damage and can lead to further decay.

A high-quality paint will stop this moisture from entering. 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 may cause mildew to develop in the window frame.

The majority of windows from the past were manufactured from timber containing an extensive proportion of sapwood. These timbers are susceptible to deterioration quickly when exposed to wet weather conditions, but they can be protected with a thorough treatment of preservative before they are put to use. It is also essential to ensure that the type of timber used is well-suited to the climate and site conditions, as these elements can affect the longevity of the joinery. Local window manufacturers create a range of sash made of timber that can be customized to fit specific historic openings. They can be built according to the standard Boston pattern dimensions or to custom sizes that are in keeping with the historic architecture.

Maintenance

Regular inspections, careful redecoration, and quick repairs can prolong the life of timber double glazed windows cambridge windows. The major cause of decay is moisture penetration through deteriorated paint or putty. This can be prevented by thorough painting and using a good quality wood preservative.
