The Often Unknown Benefits Of Cambridge Window
Maintaining Timber Windows
A well-maintained window made of timber is an important element of the historic fabric of a structure. It reflects, in various degree the technology and materials of the time period it was made, the architectural style and craftsmanship.
When repairs are feasible to windows that are already in use should be done in-situ. Repairing the worst areas of decay is possible by using specialized resin-based systems.
Durability
The windows made of wood in many old structures were designed to last for hundreds of years. They require regular maintenance to ensure they look good. Maintenance tasks include repairs to sash cords and retightening sash pulleys and painting. The demand for upgrading windows made of timber to improve efficiency in energy use is also growing. This can involve replacing old glazing units, repairing existing window rebates or putting up new cills that allow for improved air sealing.
The corrosion of paintwork is a major problem with traditional windows. This is especially true when sash windows are concerned, as the gaps between sashes may be extremely large. In these cases water can enter the paint film and cause rotting of the wood or putty underneath. Weather conditions that are not ideal can accelerate the rotting. To avoid this windows from becoming rotten, they must be painted regularly using an exterior wood paint that is suitable.
In addition to repainting, areas that have corroded should be repaired with the help of a resin-based repair solution. This will ensure that the maximum amount of the original fabric is preserved. It is also important to minimise the number of holes drilled into the frame to allow cable entry, as they could let in water and cause decay.
The structural movement of the wall could also cause distortions in the frame and the sash. This can result in the sash not fitting properly and jamming or sticking to the opening and cracked glazing. This can be corrected often by fitting new sash frames made of slow-grown deal (pine) or oak. The cill should be constructed of a durable hardwood, such as oak, in order to prevent any shifting between the new and old work.
To reduce the risk to reduce the risk of this happening, there are a variety of companies that make Boston pattern sash made of wood that will fit most existing openings. These sash are available in a variety of sizes and finishes to suit the needs of today's homeowner. Together with quadruple draught strips and a better thermal insulation, these new sash can make significant improvements to the energy efficiency of a home.
Aesthetics
Many old timber frames possess a dazzling aesthetic appeal, since they display, in a certain shape, the materials technology, design, and aesthetics of the time they were made. They may also have significant historical significance as a set. This is particularly true for windows that were unglazed in the early days of timber-framed structures, where the majority of them were series of openings within structural frames that were subdivided horizontally by mullions with vertical wood or iron bars to keep out intrusions.
It is important to maintain the appearance of traditional wooden window joinery. It is essential that any decay caused by moisture penetration should be immediately stopped once it is recognised. It is best to do this with thorough painting, especially where there has been damage or deterioration. It is best to choose paints that are intended to be used in a system (primer undercoat and finish), and to adhere to the manufacturer's recommendations for preparation and number of coats at each stage.
Wet rot is a frequent problem for old timber windows and the best way to stop it growing is to eliminate any damaged or rotten parts as soon as you can to prevent the spread of the fungus responsible for it. The replacement of wood that is rotting must be done with care by using a slow-growing deal (pine) and, if feasible using the same species as which is being removed in order to prevent any movement differences between the new and old timbers.
Glass became more affordable and abundant in the late medieval era and into the 17th century. In the process, the openings for glazed windows on timber-framed houses became more complex with moulded mullions, tracery made of wood and deep projecting cills. Increasingly, the glazing was placed within frames with rebates and secured by 'glazing sprigs' rather than into lead cames. This method of glazing is not only less susceptible to leaks, but also allows for larger clearer, more transparent 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 due to their thickness and multilayer construction as well as attention to the smallest of details. They also feature large glass areas and projection cills which reduce air infiltration. The windows can be modified to improve their energy efficiency by draught-proofing and secondary glazing. However it is crucial to keep in mind that these measures must be considered in terms of the overall appearance and integrity of the original window.
So, retaining old windows that are in need of repair rather than replacing them is logical, particularly when their thermal enhancements can be made economically through simple repairs and upgrades. The windows that are historic have a lot of historical significance, since they show a range in technical development and changes to the architectural style. The pressures to replace these windows are generally based on the assumption that old windows will need replacement in the near future, however they are capable of serving for 150, 200 or even 250 years, if properly maintained.
It is crucial to recognize that the decay issues caused by traditional timber windows can be avoided by thorough maintenance and swift repairs. It is also important to recognize damp issues 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, leading to wet rot. It is not uncommon for this type of damage to go unnoticed until paintwork starts to crack or turn curly. However, window seal repairs near me could cause structural damage and further decay.
A good quality paint will prevent this moisture penetration. It is also important to keep the paintwork clean to avoid condensation and the growth of mould. Modern synthetic paints are problematic because they are often water-resistant and may cause mildew to develop within the window frame.
The majority of windows from the past were constructed of sapwood-rich timber. These timbers can deteriorate very quickly when exposed to wet weather, however they can be protected by a thorough preservative treatment before they are used. It is important to choose the appropriate type of wood for your location and climate, as these variables can affect the durability of the joinery. Local window manufacturers offer various types of sash timbers that can be adapted to fit historical openings. They can be produced in the standard Boston pattern or in custom sizes to suit historical structures.
Maintenance
Regular inspections carefully redecorated, as well as prompt repairs can extend the life of wooden windows. The primary cause of wood decay is moisture penetration through deteriorated paint and putty. This can be avoided by using a high-quality wood preservative and thoroughly painting the wood.
It is crucial that repairs to old sash or casement windows are properly executed, and carried out without causing any disturbance. Many traditional timber window designs can be repaired without removing the frame, and this method should be followed whenever possible. Paint that is peeling or loose should be removed carefully and sanded lightly to increase the "key" of the surface, allowing for an improved adhesion of the new coating. Be careful to avoid stripping paint layers that might have historical significance, and where these are present, it is recommended that a study of the paint be carried out.
When a section of wood has rotted the best way to deal with it is to remove it and replace it with timber inserts that are shaped to match the existing profiles. The timber inserts should be treated with wood preservative, and the joint between the masonry sub-cill and the timber cill should be sealed.
It can be tempting to replace traditional windows with PVC u, particularly if the installer offers an 'all-in-one' installation which includes both replacement and removal in a single day. However, it is essential that the person installing replacement windows has a complete understanding of the construction and history of traditional wooden frames. This will allow them to make appropriate recommendations for energy-efficiency improvements and other technological advancements that won't alter the appearance of an historic building. Those who provide replacement windows should be registered under a Competent Persons Scheme like as FENSA. This will ensure that the replacements are approved under Building Regulations as a suitable option. A skilled carpenter can install PVC-u windows that conform to original building's character. This is especially relevant when windows are situated within listed buildings or conservation areas.
