Maintaining Timber Windows

A well-maintained wooden window is a crucial element of a building that is historic. It demonstrates in various degrees the materials and technologies as well as the craftsmanship and architectural style of the period from which it originates.

If possible, repairs should be made on-site. Repairing the most deteriorated areas of decay can be accomplished by using specialized resin-based systems.

Durability

The windows made of timber in many historic buildings were made to last for centuries. But, they have to be maintained to keep them looking great and working properly. Maintenance tasks include repairs to sash cords as well as tightening the sash pulleys and painting. The demand for upgrading timber windows to increase efficiency in energy use is also growing. This can involve replacing old glass units, fixing the window seal replacement near me rebates that are in place or putting up new cills that allow for improved air sealing.

The deterioration of paintwork is a major issue with traditional windows. This is especially true when it comes to sash windows, as the gaps between sashes can be extremely large. In these cases water can enter the paint film and cause rotting to the wood or putty beneath. The weather can be a factor in accelerating the rotting. To prevent this from happening, windows must be painted regularly with an exterior wood paint.

In addition to repainting, areas that have corroded must be repaired using an adhesive-based repair product. This will ensure the maximum amount of original fabric preserved. It is crucial to reduce the number of holes that are made into the frame in order to allow cable entry because they could let in moisture and cause decay.

Another issue with older windows is structural movement in the wall that can cause deformation of the frame and the sash. This can result in sash no longer fitting correctly or sticking or jamming into the opening and broken glazing. This can be corrected often by putting in new frames for sash made of slow-growing deal (pine), or oak. The cill must be constructed of a durable hardwood like oak to avoid any movement between the new and existing work.

There are several companies that produce Boston pattern wooden sash window Repair Cambridge that fit into the majority of existing openings. These sash are available in a variety of sizes and finishes to suit the needs of the modern homeowner. In conjunction with quadruple draught strip and improved thermal insulation, these sashes can make a a substantial difference to the energy efficiency of a home.

Aesthetics

A lot of old timber frames have a great aesthetic appeal, as they reflect, in some shape, the materials, technology, and architectural style of the time they were built. They also may have significant historical value in their in their own right. This is especially true of 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 vertical iron or wood bars in order to protect against invaders.

Traditional timber window joinery can be a stunning aspect of a building, and it is important to keep its appearance. As soon as you see any signs of decay caused by the penetration of moisture it is essential to stop it. This can be done by applying a thorough coat of paint, particularly in areas where there has already been damage or degradation. It is best to choose paints that are intended to be used in a set (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 common problem for old timber windows and the best method to stop it from developing is to remove sections that are damaged or rotten as soon as possible to stop the spread of the fungus responsible for it. The replacement of rotting wood must be done with care by using a slow-growing deal (pine) and, wherever possible it is the same species as that which is being removed in order to prevent differential movement between the new section and existing timbers.

Glass became cheaper and more abundant in 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 double glazing cambridge was increasingly 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 it can allow for larger, clearer sheets of glass to be used in windows than would have been possible without the need for leaded lights.

Energy efficiency

Traditional timber windows are energy efficient due to their thickness, multilayer construction and focus on detail. They also feature large glass areas as well as deep projecting cills that reduce air infiltration. With secondary glazing and draught proofing, windows can be upgraded to improve their energy efficiency. However, it is important to keep in mind that any such measures must be considered in the context of the overall integrity and appearance of the original window.

It makes sense to fix or upgrade windows, rather than replacing them, particularly when improvement in energy efficiency can be made through simple fixes. Older windows are usually of historical value, as they reflect a variety of technological advancements and changes to the architectural style. Most people assume that these windows will have to be replaced in the near future. However, they can still provide service for 150, 200 or even 250 years if they are maintained with proper maintenance.

It is essential to realize that decay issues in traditional timber windows are avoidable with quick and thorough repairs. Additionally, it is essential to identify damp penetration problems and to remedy them quickly to avoid major damage. The early deterioration of paint is a particular problem, as it allows moisture to penetrate the wood and cause wet rot. The damage is usually not evident until the paintwork is wavy or cracked, but can cause significant structural damage and lead to further decay.

A high-quality paint will prevent this moisture from entering. To prevent condensation and mould it is crucial to keep the paintwork as clean as you can. Modern synthetic paints are problematic because they are water-resistant and can cause mildew to grow within the window lock repairs frame.

The majority of windows from the past were constructed from sapwood-rich wood. The timbers will deteriorate rapidly if exposed to wet weather, but can be protected with a thorough preservative treatment before they are used. It is crucial to select the right type of wood for your location and the climate, since these factors can affect the durability of the joinery. Local window manufacturers have a wide range of sash made from timber that can be customized to fit historic openings.

Maintenance

Regular inspections carefully redecorated, as well as timely repairs can prolong the life of wooden windows. The major cause of decay is moisture penetration through the deteriorated paint and putty. This can be avoided by thorough painting and the use of high-quality wood preservative.

Repairs to old sash windows as well as frameless casement windows should be done with care and minimal disruption. A lot of traditional wooden window designs are repairable without removing the frame, and this approach should be used whenever it is feasible. Remove peeling or loose paint and then lightly sand the surface to improve the "key" of the surface. This will allow the new coating to adhere better. It is essential to avoid removing old paint layers, which may have historical value.

If a piece of wood is decayed, the best solution is to take it off and replace it with timber inserts designed to match the existing profiles. The timber inserts should be treated with wood preservative. The junction between masonry sub-cills and timber cill should be sealed.

Replacement of traditional windows with PVC-u can be an appealing option, particularly when the installer offers an "all-in-one" installation that handles removal and replacement in a day. It is, however, essential that the person installing replacement windows has a full understanding of the construction and history of traditional timber frames. This will enable them to make the right suggestions for energy efficiency improvements and other technical upgrades that will not harm the character of a historic building.
